Side passage
You have about 32–36 cm of depth and you will drill the inlet. The Pluto 100 litre kit states that footprint, a stand, a diverter and a tap, with 4.5 from 283 reviews at about £33.69.
Water butt comparison 2026
The best water butts, compared.
Top pick: VeftBltrem 200 litre collapsible Best value: Bowers 100 litre kit – A 100 litre slimline kit at about £39.99, with 4.3 from 72 reviews, if the diverter is in the carton. Updated October 2026.
A water butt stores roof rain so you can water plants without using that volume from the mains. These 11 amazon.co.uk listings are rigid slimline kits of about 100 litres, rigid tanks of 210–250 litres, or collapsible PVC tanks titled from 200 litres to a conflicting 350/380 litre pair. Judge a listing by the box contents, a capacity line that matches the size, and how often UK reviews repeat one fault. The water is not for drinking, and a temporary use ban still binds the company's own supply. A raised tap is for filling a [watering can](/hub/garden-watering/watering-can), not for hose pressure. The 11 amazon.co.uk listings fall into three groups.

Where will the butt stand?
The best water butts in detail
Our view
The VeftBltrem listing is a green 840D PVC barrel at £43.99 and 2.1 kg, and the title names a stand, a tap, a downspout kit and an overflow. amazon.co.uk shows 5.0 from 5 reviews, and three texts are stored. The title and bullets say 200 litres, while technical details say 52.8 gallons and do not state the gallon unit. The listing says setup takes about 2 minutes with no tools, and that folding saves about 80 percent of the storage space. Two reviews call it sturdy and easy, one likes the tap halfway down and moving it to a greenhouse, and the third buyer had not assembled it. Those three texts do not describe a leak, a collapse, or a missing part, and they do not test the puncture or UV claims. Five reviews are not the same evidence as 4.5 from 283 on the Pluto kit. You open it for a fold-flat barrel with a named stand only if you can wait for a larger review pool.
Pros
- Title names a stand, tap, downspout kit and overflow, at £43.99 and 2.1 kg
- Listing says about 2 minutes, no tools, and about 80 percent less storage space when folded
- Two stored reviews call it sturdy and easy to move
- Tap is described halfway down
Cons
- Only five reviews, and one of the three stored texts is from a buyer who had not assembled it
- Title says 200 litres and technical details say 52.8 gallons with the unit unstated
- No dimensions are printed
- Puncture and UV claims are not tested in the stored reviews
Best for: A fold-flat barrel with a named stand, if five reviews are enough for you to try it.
Less suitable: Anyone treating 5.0 as a rank, or a buyer who needs a printed footprint before ordering.

Common questions
Which capacity is printed?
The title and bullets say 200 litres. Technical details say 52.8 gallons. The unit on that gallon figure is not stated in the technical details.
Does it fold away?
Yes. The listing says it folds flat and claims about 80 percent less storage space. Setup is described as about 2 minutes with no tools.
Do the captured reviews name a fault?
Three captured reviews do not describe a leak, collapse or missing part. One buyer had not assembled it. The star line is 5.0 from 5 reviews.

The Original Organics STA-GN355BLK is a 250 litre black kit at £79.99 and 6.5 kg, and the title names a tap, a lid, a stand and a diverter. amazon.co.uk shows 4.8 from 10 reviews, and only four texts are stored. The bullets call the shape square and compact for a wall or a tight gap, while technical details print the shape as round and the width as 540 centimetres, which is the raw string and not a usable measurement. The four texts praise easy fitting, clear instructions, and a threaded tap boss so you do not reach inside for a nut. One buyer already has three of this type and says they seem to last. The only stated snag is the stand: it has to face the right way before a watering can fits under the tap. Those four texts do not describe a leak, a crack, or a missing part, and they do not confirm whether a length of downpipe is in the box. Ten reviews cannot carry the same weight as 4.2 from 1,149 on the Whitefurze kit at the same £79.99.
Pros
- Title names tap, lid, stand and diverter with the 250 litre butt
- Threaded tap boss, so the nut does not have to be reached from inside
- Four stored texts praise the fit against a wall
- 6.5 kg empty, lighter than the Whitefurze kit at the same £79.99
Cons
- Only 10 reviews and four stored texts
- Width printed as 540 centimetres, and shape is round in technical details but square in the bullets
- Stand must be turned the right way before a watering can fits
- A downpipe length is asked on the listing and not confirmed
Best for: A 250 litre kit with a named stand, if you will measure the butt yourself and can accept ten reviews.
Less suitable: Anyone sorting by the 4.8 stars, or a gap you size from the printed 540 centimetre width.

Common questions
What does the Original Organics kit include?
The title and bullets name a tap, lid, stand and diverter with the 250 litre butt. Whether a length of downpipe is included is asked on the listing and not confirmed.
Is the shape square or round?
The bullets describe a square, compact shape for walls and tight gaps. Technical details print the shape as round, and the width as 540 centimetres.
Does a watering can fit under the tap?
One buyer says the stand has to be turned the right way before a watering can fits underneath. The tap boss is threaded, so the nut does not have to be reached from inside.
Our view
The Pluto 5625 is a 100 litre black slimline kit at £33.69, with a stand, diverter, tap, T-piece and flexible hose, and the item highlight also names a lid. amazon.co.uk shows 4.5 from 283 reviews, and 50 texts are stored. Bullets and technical details both give 32 × 36 × 95 cm, and the stand is 40.5 × 40.5 × 30.5 cm, which is the footprint buyers cite for a corner or a side passage. The stand lifts the tap enough for a watering can, and many reviewers found the kit straightforward once the parts came out of the tank. You still drill the inlet: the holes are not open on arrival. The four-part stand unclips if you move the butt, the tap can drip once the tank is heavy and no washer is supplied, and one full butt buckled under the water. A few units arrived with a hole already in the side, a damaged base, or a tap the seller replaced the next day. You buy it for a narrow gap when you will drill the inlet and you will not treat the thin plastic as a heavy-duty tank.
Pros
- 100 litres at 32 × 36 × 95 cm, on a stand about 30.5 cm high
- Stand, diverter, tap, T-piece and hose are named, and the highlight names a lid
- 4.5 from 283 amazon.co.uk reviews at £33.69
- Buyers use it in corners where a round 250 litre butt will not fit
Cons
- Inlet is closed on arrival and has to be drilled
- Four-part stand unclips when the butt is moved
- Tap can drip once the tank is heavy, and no washer is supplied
- One full butt buckled, and some units arrived damaged
Best for: A side passage or small patio, if you will drill the inlet and fill a watering can.
Less suitable: A buyer who wants the holes open on arrival, or a tank you will drag while it is full.

What comes in the Pluto kit?
The listing includes a stand, diverter, tap, T-piece and a flexible hose. The item highlight also names a lid. A washer for the tap is not included, according to one buyer.
How large is the footprint?
Bullets and technical details both give 32 cm by 36 cm by 95 cm for the butt. The stand is given as 40.5 cm by 40.5 cm by 30.5 cm.

The Bowers Bb210wb is a 210 litre black cylinder at £48.95 and 5 kg, about 57 × 57 × 97 cm, with a built-in tap and a lockable lid. amazon.co.uk shows 4.5 from 39 reviews, and 19 texts are stored. Reviewers call the barrel sturdy and well finished, and one reported no issues after four months. A stand is not listed, and one buyer raised the butt on an old car wheel so a can could still reach the tap. A diverter kit is not in the box either. One supplied tap leaked from day one and was called cheap, so that buyer fitted a tap kept from an older butt, and one lid was a bit loose although it still locked. Several buyers had not had enough rain to judge the seal. You buy the extra litres at £48.95 only if you already have a firm plinth and a way to get water in from the downpipe.
Pros
- 210 litres at about 57 × 57 × 97 cm and 5 kg, for £48.95
- Built-in tap and a lockable lid
- 4.5 from 39 reviews, with buyers calling the body sturdy
- Markings on the barrel for different setups
Cons
- No stand, so the tap is too low unless you raise the butt
- No diverter kit in the stated box
- One tap leaked from day one and was replaced with an older tap
- One lid was loose, and several buyers had not had enough rain to judge the seal
Best for: A 210 litre store when you already have a plinth and a separate diverter.
Less suitable: A first kit, or a watering can that must sit under a tap at ground level.

Common questions

Is a diverter included?
A diverter kit is not listed. The stated scope is the butt with a tap and a lockable lid.
Does the lid lock?
The listing calls the lid lockable. One buyer found it a bit loose, but said it does lock.

The BeGrit ge1883Z1 is a green collapsible PVC barrel at £59.99 and 3.37 kg, with support poles, ground stakes, straps, taps and an overflow, and amazon.co.uk shows 4.4 from 25 reviews with 19 texts stored. The title and bullets say 380 litres, and technical details say 350 litres. The listing says it can sit under an existing downpipe with no cutting and no diverter, and it folds flat for winter. Reviewers call the PVC thick once it holds water, and several state about 380 litres. The middle tap is repeatedly too weak for a hose, and slow even for a can, so some buyers dip through the zip mesh instead. Support struts bent after filling for one buyer, the tap area leaked after fitting, four ground anchors arrived for five struts, and the lower tap is open when it looks straight. Empty, it is light enough to blow across the garden unless you peg it. You buy the folding volume if a can dipped from the top is enough, and you skip it if you need hose pressure.
Pros
- Folds flat, and the listing says it sits under a downpipe with no cut and no diverter
- 4.4 from 25 reviews; buyers call the PVC thick once it holds water
- Overflow pipes can link a second barrel
- Stakes and straps are in the description for wind
Cons
- Title says 380 litres and technical details say 350 litres
- Middle tap is too weak for a hose and slow for a can
- Support struts bent for one buyer, and four anchors arrived for five struts
- Lower tap is open when it looks straight, and the empty barrel blows away unless pegged
Best for: Winter storage of an empty tank, if you will dip a can through the mesh rather than run a hose.
Less suitable: Hose pressure, a side passage, or a buyer who needs one capacity figure.

Common questions
Is the capacity 380 litres or 350 litres?
The title and bullets say 380 litres. Technical details say 350 litres. Both figures are in the listing.
Do you need a downpipe diverter?
The listing says it can sit under an existing downpipe with no cutting and no diverter. A supplied diverter kit is not stated.
Can you empty it through a hose?
Reviews repeatedly say the middle tap has low pressure, so a hose is a poor way to empty it. Some buyers dip a can through the top.

The Mekturm K-RB-02 is a collapsible PVC barrel at £41.99 and 2.12 kg, and the title names a stand, a tap, a filter, a spigot and an overflow kit. amazon.co.uk shows 4.4 from 3 reviews, and no review text is stored. The bullets say 53 gallons as 200 litres, while technical details say 53 gallons, and the colour is black in technical details and classic green in one bullet. The listing says you screw the tap in with no tools, place the barrel under a downpipe, and fill it to about 20 percent first so it stays put. It folds flat for a shed or garage. A separate diverter is not described, dimensions are not stated, and the title's stand is described in the bullets as circular footpads rather than a raised plinth for a watering can. Three stars with no stored text cannot show whether the tap drips or the frame sags. You buy the fold-flat claim only if you can accept a rating line with nothing behind it.
Pros
- Folds flat, at 2.12 kg and £41.99
- Title names a filter, spigot, tap and overflow kit
- Listing says no tools, and to fill about 20 percent first so it stays put
- Zipped mesh lid is described against leaves and wildlife
Cons
- Only three reviews, and no review text is stored
- Bullets say 200 litres and technical details say 53 gallons; colour is black and also classic green
- No dimensions, and no separate diverter is described
- The named stand reads as footpads, not a raised plinth for a can
Best for: A fold-flat barrel you will place under a downpipe, if three reviews with no text are enough.
Less suitable: Anyone who needs a measured footprint, a raised tap, or a fault list from buyers.

Which capacity and colour are printed?
The bullets say 53 gallons / 200 litres. Technical details say 53 gallons. Colour is black in technical details and classic green in one bullet.

The Pluto sml12 listing is two 100 litre black slimline tanks at £66.99, each with a stand and a filler kit. amazon.co.uk shows 4.3 from 231 reviews, and 50 texts are stored. Each butt is about 32 × 36 × 95 cm, with a stand about 30.5 cm high, and reviewers use the pair in a side passage. Instructions ask for a 27 mm hole; reviewers used 25 mm or 26 mm bits. The photos show the tanks joined, but a butt-to-butt connector is not in the box, so linking needs an extra connector and often a third spigot, and the link outlet angles upward so the second tank fills only after the water rises. Push-fit joints seep unless you add a jubilee clip, the four-part base stays loose until the tank is heavy, and empty butts were blown over. One diverter did not fit a square downpipe. You buy the pair for two separate downpipes, and you do not buy it if the picture of a linked pair is the job you need on day one.
Pros
- Two 100 litre slimline tanks, each with a stand and a filler kit, at £66.99
- 4.3 from 231 amazon.co.uk reviews
- Footprint about 32 × 36 × 95 cm suits a side passage
- Stable once they hold water, and one buyer left four full through a freezing winter without a split
Cons
- Butt-to-butt connector is not in the box, despite photos of a joined pair
- You drill a 27 mm hole, and push-fit joints seep without a jubilee clip
- Link outlet points upward, so the second butt fills late
- Empty tanks blow over, and one diverter missed a square downpipe
Best for: Two separate downpipes in a narrow garden, if you will drill each inlet.
Less suitable: A linked pair on day one, or a square downpipe the diverter does not match.

Common questions
Can the two butts be linked as the photos show?
Buyers say a butt-to-butt connector is not in the box. Linking needs an extra connector and often a third spigot.
Do you have to drill a hole?
Yes. Instructions state a 27 mm hole. Reviewers used 25 mm or 26 mm bits.
Will they stand up when empty?
Empty butts are light and were blown over in wind. Reviews suggest keeping some water in them, or standing them on level paving.

The Bowers Bb100sl is a 100 litre black slimline set at £39.99 and 5 kg, and the listing says the tank, a four-part stand and a downpipe diverter kit are included, with a tap and a lid. amazon.co.uk shows 4.3 from 72 reviews, and 31 texts are stored. Bullets give about 32 × 36 × 95 cm and a stand about 30.5 cm high; technical details print 36 × 32 × 96 cm. Country of origin is printed as United Kingdom. Many boxes included drainpipe fittings and parts to link a second butt, and at least one buyer filled a watering can with no tap leak. You still need a 27 mm hole cutter, the base falls apart if you lift the empty butt, and one box arrived with no diverter, no connecting pipe and no instructions. One tap only partly opened until it was reassembled, and one butt had a hole about 4 inches from the bottom that was sealed with mastic. You take it as the nearby slimline kit when Pluto's larger review pool is not the priority, and you check the diverter is actually in the carton.
Pros
- 100 litre slimline at about 32 × 36 × 95 cm with a stand about 30.5 cm high
- Listing names tank, stand, diverter kit, tap and lid, at £39.99
- 4.3 from 72 reviews, and country of origin is printed as United Kingdom
- Many boxes include fittings to link a second butt
Cons
- A 27 mm hole has to be drilled
- Four-part base falls apart if you lift the empty butt
- One box had no diverter, no connecting pipe and no instructions
- One tap only partly opened, and one butt had a hole about 4 inches from the bottom
Best for: A narrow gap when you want a stated British-made kit and will check the carton for the diverter.
Less suitable: A buyer who will not drill, or a layout that depends on a diverter the box might omit.

Common questions
Is the downpipe kit in the box?
The listing says the set includes the tank, a stand and a downpipe diverter kit, and that it suits standard round downpipes. One buyer reports no diverter, no connecting pipe and no instructions.
Do you need a drill?
Yes. A 27 mm drill or hole cutter is required. The four-part stand is assembled on site.
Where does the listing say it is made?
Country of origin is printed as United Kingdom, and the listing says manufactured in Britain.

The Whitefurze G29WB25G is a 250 litre forest-green kit at £79.99, listed at 8.52 kg, with a three-part stand, diverter, T-piece, tap and flexible hose. amazon.co.uk shows 4.2 from 1,149 reviews, and 50 texts are stored. Technical details print 112 × 54 × 112 cm, and one buyer says the stated height of 1.11 m leaves the stand out. Many buyers assemble it quickly when the bosses are already open, and several call the lid secure. The repeated fault is the tap: it drips around the thread until it is reseated, taped, given an extra turn, or replaced, and it will not take a hosepipe connector. The listing says internally threaded bosses so you need no drill, yet several butts arrived with the tap hole and the fill hole still sealed. The T-piece pipe is about 15 mm, which one buyer could not match to other brands, there is no overflow, and the diverter will not work with a 36 mm downpipe. A few stands arrived with a broken lug or a cracked section, and one side melted after about three months in hot weather.
Pros
- 250 litre kit at £79.99 with stand, diverter, T-piece, tap and hose named
- 4.2 from 1,149 amazon.co.uk reviews, with 50 texts stored
- Buyers who found the bosses already open report a quick fit and a secure lid
- T-piece is in the box for a second Whitefurze butt
Cons
- Tap drip is the repeated complaint, and the tap will not take a hosepipe connector
- Several butts arrived with sealed tap and fill holes despite the no-drill line
- No overflow, the T-piece is about 15 mm, and the diverter misses a 36 mm downpipe
- Broken stand lugs, a cracked base, and one side that melted after about three months
Best for: A 250 litre store beside a round downpipe, if you will check the bosses and reseat the tap.
Less suitable: A 36 mm downpipe, a hosepipe on the supplied tap, or a buyer who needs an overflow in the box.

Common questions
What is in the Whitefurze kit?
The listing includes a stand, diverter, T-piece, tap and flexible hose with the 250 litre butt. Extra tap washers are not included.
Do you have to drill the tap hole?
The listing says internally threaded bosses so no drilling is required. Several buyers found the tap hole and fill hole still sealed and had to drill or hammer them out.
Will the tap take a hosepipe?
Buyers say the supplied tap is not made to take a hosepipe connector. Some added PTFE tape, an extra washer, or a separate butt connector.

The Strata Sl100uk is a 100 litre black kit at £33.89 and 3.5 kg, and the title calls it a UK-made slimline tank with a stand and a filler kit. amazon.co.uk shows 4.0 from 46 reviews, and 18 texts are stored. Technical details print 60 × 60 × 90 cm, and no second measurement set is given, so the slimline claim and the footprint do not agree. One buyer followed the instructions in about 20 to 30 minutes, and another added a second butt. The filler kit does not fit square downpipes, according to one buyer, and another fitted the hose from the drainpipe and the tank still did not fill. A tap is not named in the feature bullets, yet reviews discuss a leak from the seam under the tap and a tap that does not feel as if it will last. The base is called flimsy, it does not click together well, and an empty kit was blown over until a brick went in the bottom. You only buy the lowest price in this set after you have measured a 60 cm square and checked the downpipe shape.
Pros
- £33.89 for a 100 litre kit that names a stand and a filler kit
- 4.0 from 46 reviews, and one setup took about 20 to 30 minutes
- One buyer linked a second butt
- Bullets say the tank is manufactured in the UK
Cons
- Technical details print 60 × 60 × 90 cm while the title says slimline
- Filler kit missed square downpipes, and one fitted hose did not fill the tank
- Leak from the seam under the tap, and the tap is not named in the bullets
- Flimsy base, and an empty kit blew over
Best for: A 60 cm square you have already measured, on a round downpipe, if the price is the reason you are here.
Less suitable: A 32 cm side passage, or a square downpipe.

One buyer says it does not fit square downpipes. Another fitted the hose from the drainpipe and the butt still did not fill.
Is a tap named in the bullets?
A tap is not named in the feature bullets. Reviews discuss a tap, including a leak from the seam under the tap.
Our view
The FZYY Rwc-fpt-001 is a green collapsible collector at £51.99, stated as 250 litres, 40 × 40 × 100 cm and 1.5 kg. The listing names a side tap, a lower drain, an upper overflow, a mesh inlet, a zip-up top and a clear water-level tube. amazon.co.uk has no review line and no stored review text, so there is no star rating to read. A stand is not stated, and a downpipe diverter is not stated. The material line names polyethylene and PVC, and the specification field cites a food-grade claim, ISO 9001 and RoHS. Food-grade plastic on a listing is not a statement that the collected water is for drinking. Setup time is asked on the page and not answered. You can compare the outlets and the 40 cm footprint on paper, and you cannot judge leaks, tap flow, or winter folding from buyers, because none are recorded here.
Pros
- 250 litres stated at 40 × 40 × 100 cm and 1.5 kg, for £51.99
- Side tap, lower drain, upper overflow, mesh inlet and a water-level tube are named
- Collapsible, so the empty shell is meant to pack away
- Footprint is printed, unlike several other PVC listings in this set
Cons
- No review line and no stored review text
- Stand and downpipe diverter are not stated
- Setup time is asked on the listing and not answered
- A food-grade line is not a claim that the water is for drinking
Best for: A 40 cm square footprint you can compare on the listing, if you do not need buyer reports.
Less suitable: Anyone choosing by stars, or a raised stand and a diverter you expect in the box.

Common questions
Is there a star rating on this listing?
No. The amazon.co.uk listing has no review line and no review text, so a star rating is not available.
What outlets does the listing name?
A side tap, a lower drain valve and an upper overflow outlet, plus a mesh inlet and a zip-up top.
Does it include a stand or a diverter?
A stand is not stated, and a downpipe diverter is not stated. Dimensions are given as 40 cm by 40 cm by 100 cm, and the weight as 1.5 kg.
How we compared
For this comparison we read 11 amazon.co.uk water butt listings, priced on 15 October 2026, and the public UK sources below. The stored score is the star rating times 20. A 5.0 from five reviews is not treated as equal to a larger pool, and a listing with no review line scores 0. We did not run a laboratory fill test, a frost test, or a measured tap-flow test.
1
Space and footprint
25%Measure the gap first. Slimline kits here are often 32–36 cm deep and about 95 cm tall, on a stand about 30.5 cm high. A printed 60 cm square is a different job.
2
Kit in the box
25%Look for a tank, stand, tap, lid and diverter, or a clear plan to sit under the downpipe. A photo of two linked butts is not a connector in the carton.
3
Material and empty weight
15%PVC empty weights here are about 1.5–3.4 kg. The larger rigid butts are about 5 kg and 8.52 kg. Fold-flat needs an empty, dry tank. No listing includes a pump.

Capacity that matches
15%Keep a title and a technical-details line that disagree, including 380 against 350 litres and a width printed as 540 centimetres. Waterwise's typical range is 100–300 litres.

Reviews and shelf price
20%Prices on these listings run from about £33.69 to £79.99. A 4.5 from 283 reviews outweighs a 5.0 from five, or a listing with no review line.

Water butt buying guide
Measure the gap, then read what is actually in the box. A capacity line that disagrees with itself, and a star line with only a handful of reviews, should change the shortlist.
What is a water butt?
A water butt in this comparison stores roof rain so you can water plants without using that volume from the mains. The 11 amazon.co.uk listings fall into three groups. Rigid slimline kits of about 100 litres name a stand and a diverter or filler: the Pluto single, the Pluto pair, the Bowers 100 litre kit and the Strata Sl100uk. Rigid tanks of 210–250 litres are the Bowers 210 litre butt, the Original Organics kit and the Whitefurze kit.
Best for
- A side passage with a 100 litre slimline kit, a stand and a diverter
- A 210–250 litre store when the bullets name a stand
Not ideal for
- Drinking water, or a mains top-up without an air gap
- Hose pressure from a collapsible tap
Mistakes to avoid
- 1
No stand under the tap
Without a stand, the tap is too low for a watering can. The Bowers 210 litre listing does not include a stand. One buyer raised that butt on an old car wheel.
- 2
Trusting the linked-pair photo
Pluto twin reviewers say a butt-to-butt connector is not in the box, even where the photos show the tanks joined. Linking needs an extra connector.
- 3
Leaving a full butt out in frost
Drain the butt, disconnect the diverter and leave the tap open before a hard frost. A no-drill line is also unsafe to trust when reviews describe sealed bosses.
What to weigh up
Space and the kit in the box
HighSpace is the first cut because a 100 litre slimline that will not fit the passage is the wrong tank, however complete the kit. Pluto and Bowers quote about 32 × 36 × 95 cm and a stand about 30.5 cm high. Strata prints 60 × 60 × 90 cm while the title says slimline, so measure before you treat that title as a side-passage butt. The kit you want is a tank, a stand, a tap, a lid and a diverter, or a stated plan to sit under the downpipe with no cut.
Capacity conflicts and review evidence
HighA capacity line is only useful when the title and the technical details agree. BeGrit says 380 litres in the title and 350 litres in technical details. Mekturm says 200 litres in the bullets and 53 gallons in technical details. VeftBltrem says 200 litres in the title and 52.8 gallons in technical details, with the gallon unit unstated. Waterwise's typical range is 100–300 litres, and the RHS treats about 240 litres as a standard butt. Then read the review pool.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Larger downpipe
You want 210–250 litres and a stand named in the bullets. The Whitefurze 250 litre kit states a stand, diverter, T-piece, tap and hose, with 4.2 from 1,149 reviews at about £79.99. Check the bosses and reseat the tap.
Winter storage
You will empty the tank and fold it away. Collapsible PVC in this set is about 1.5–3.4 kg empty, and the taps are slow. The BeGrit barrel has 4.4 from 25 reviews. Dip a can rather than expect hose pressure.
Common questions about water butts
Which water butt is the top pick for a narrow gap?
The top pick is the Pluto 100 litre kit, model 5625, for a side passage. It is listed at about 32 × 36 × 95 cm, with a stand about 30.5 cm high, a diverter, a tap, a T-piece and a hose, at about £33.69. amazon.co.uk shows 4.5 from 283 reviews. You still drill the inlet, the tap can drip once the tank is heavy, and one full butt buckled. That is the top pick for a narrow gap if you accept those faults.
Which water butt is the best value?
The best value is the Bowers 100 litre kit, model Bb100sl, at about £39.99, with 4.3 from 72 reviews. The footprint is about 32 × 36 × 95 cm, on a stand about 30.5 cm high. The listing names a tank, stand, diverter kit, tap and lid, and country of origin is printed as United Kingdom. You still drill a 27 mm hole. One buyer found no diverter, no connecting pipe and no instructions, so check the carton. Strata is cheaper, but it prints 60 × 60 × 90 cm.
How much does a water butt cost on amazon.co.uk?
On these 11 listings on 15 October 2026, entry prices are about £34–£40: Pluto at £33.69, Strata at £33.89 and the Bowers 100 litre kit at £39.99. The middle band is about £42–£67, from the Mekturm collapsible at £41.99 to the Pluto pair at £66.99. Both 250 litre rigid kits, Original Organics and Whitefurze, are £79.99. These are shelf prices on that date, not a promise of the lowest price.
What should you check before you buy a water butt?
Measure the gap first. Slimline kits here are often 32–36 cm deep and about 95 cm tall, on a stand about 30.5 cm high. Then read the box for a tank, stand, tap, lid and diverter, or a plan to sit under the downpipe. The Bowers 210 litre states a lid and a tap, not a stand. Pluto twin reviewers say the joining piece is not in the box. A 5.0 from five reviews is weaker evidence than 4.5 from 283.
Is collecting rainwater in a water butt legal in the UK?
The RHS says collecting roof rain is legal if you use a firm, level base, a filter and a lid. The water is for the garden, not for drinking. BS EN 16941-1:2024 covers designed non-potable systems and excludes drinking water, and no listing here claims that standard. A mains top-up needs an air gap under the Water Supply (Water Fittings) Regulations 1999. Toilets or a pump are installer work. A food-grade line does not make the water safe to drink.
Can you use a water butt during a hosepipe ban?
Section 76 of the Water Industry Act 1991 lets a company ban specified uses of water it supplies. Ofwat describes the maximum fine as up to £1,000 and says a watering can is still allowed. Thames Water's notice of 15 October 2026 still allows stored rain and a can. Other notices differ, so read yours. Do not refill from the mains to dodge a ban. What a hosepipe ban still allows depends on that notice.
Do you have to drill a water butt before it will fill?
It depends on the listing. The Pluto 100 litre kit arrives with the inlet closed, and buyers drill it. The Pluto pair and the Bowers 100 litre kit state a 27 mm hole. Whitefurze says internally threaded bosses so no drilling is required, yet several buyers found the tap hole and the fill hole still sealed. BeGrit says it can sit under a downpipe with no cutting and no diverter. Check the bosses before you trust a no-drill line.
How do you prepare a water butt for frost?
Before a hard frost, drain the butt, disconnect the diverter and leave the tap open. Screwfix describes that for a diverter: excess rain returns down the pipe in normal use, and the butt should be emptied before frost. Fold-flat PVC should be empty and dry before you pack it away. None of these listings is treated here as frost-proof. RoSPA warns that young children can drown in very small amounts of water, so fit a lid or fence the butt.
Our verdict
For a narrow gap, the top pick is the Pluto 100 litre kit, model 5625: about 32 × 36 × 95 cm, a stand, diverter, tap, T-piece and hose, and 4.5 from 283 reviews at about £33.69. You still drill the inlet, the tap can drip once the tank is heavy, and one full butt buckled. If you want a second slimline kit in that footprint, the best value is the Bowers Bb100sl at about £39.99, with 4.3 from 72 reviews, if the diverter is actually in the carton. One review says the diverter, the connecting pipe and the instructions were missing.
