Top pick: URASISTO 3-piece spirit level set – Top pick for shelves and short fittings: 12 in, 20 in and 40 in at £35.99, with 4.8 from 391 reviews, once you have flip-tested a thin UK review sample. Best value: TOUGH MASTER magnetic 3-piece set – Best value at £45.99 if you want 0.5 mm/m stated and a magnet on every piece, with 4.4 from 170 reviews, and you will still flip-test the vials. Updated October 2026.
A spirit level set is two or more bubble levels sold together, so you can check a short fitting and a longer run without pretending one length does both. In the UK that usually means a short level for a socket or a bracket, a mid length for a door or a shelf, and a longer level for a stud or a wall.
Tell a useful set from a loose bundle by the lengths, then by a stated accuracy you can check. A torpedo near 250 mm, a 600 mm level and a 1,200 mm level cover most second-fix work. Add about 1,800 mm only for long walls, screeds and full-height frames. Which span does which job is set out in the [spirit level set lengths](/hub/measuring-and-marking-tools/spirit-level-set/sub/spirit-level-set-which-lengths) guide.
Prefer a listing that prints 0.5 mm/m in the normal position, about half a millimetre over one metre, then flip the level so the bubble agrees both ways. A closed box you cannot bend is the stiffer frame, and a magnetic title does not mean every piece has a magnet.

At £35.99, the URASISTO three-piece set gives you 12 in, 20 in and 40 in aluminium levels for a short fitting rather than a full-height wall. The title states magnetic torpedo levels, and the bullets add 45°, 90° and 180° vials with plastic shock-absorbing ends. The UK listing shows 4.8 from 391 reviews, the highest star rating in this table, but the file contains only four short United Kingdom reviews, so that average is a thin UK sample. The listing claims 0.0005 inch/ft. That figure is not a measured result here, and you should flip-test the vials before you trust a shelf or a door. The bullets describe a carry bag, while Included Components prints no, so check the parcel before you assume the bag arrived. There is no 48 in or 72 in piece, and at 1.87 kg this is a light set you would not want knocked about on a slab.
Pros
12 in, 20 in and 40 in in one set
4.8 from 391 reviews, the highest star rating here
Magnetic torpedo wording and 45°, 90° and 180° vials
£35.99, with a carry bag stated in the bullets
Cons
Only four short UK reviews in the file
0.0005 inch/ft is a listing claim, not a measured result
Included Components prints no bag
No 48 in or 72 in length
Best for: Shelves and short fittings where 40 in is the longest run you need.
Less suitable: Site work that needs a stiff 1,200 mm box, or a buyer who wants a large body of UK review text.
The OX Pro set is a 600 mm and a 1,200 mm box-section level, 66 mm by 30 mm, listed at £82.99. You get a stated 0.5 mm/m, a fine-milled top and bottom, horizontal and vertical vials, silicone handles, shock-proof end caps and a lifetime vial warranty. The UK listing shows 4.6 from 2,286 reviews. Many of the UK reviews in the file describe a torpedo, a boat level or a single OX level, so magnet and holster complaints are mixed-listing noise unless the review names this set. The bullets do not call the set magnetic and do not include a bag, although one review that names the set likes a carry case. At 2.89 kg it is a heavy pair for doors and studs. You get no torpedo, no 45° vial and no 1,800 mm level.
Pros
66 mm by 30 mm box section, fine-milled top and bottom
Stated 0.5 mm/m and a lifetime vial warranty
Silicone handles and shock-proof end caps
4.6 from 2,286 reviews
Cons
Many reviews on the listing describe other OX levels
Not stated as magnetic, and no bag in the bullets
No torpedo, no 45° vial and no 1,800 mm length
£82.99 for two lengths
Best for: Site work on doors and studs if you want a stiff milled 600 mm and 1,200 mm pair.
Less suitable: Jobs that need magnets, a bag, a torpedo or an 1,800 mm level.
The listing states 600 mm and 1200 mm. The profile is a 66 mm x 30 mm box-section aluminium extrusion.
Is this set magnetic?
The product bullets do not say magnetic. Horizontal and vertical readings are stated. A 45° vial is not stated.
What accuracy and warranty are stated?
0.5 mm/m is stated, with vials described as UV-resistant and individually calibrated. A lifetime vial warranty is stated. A bag is not stated in the bullets.
The Milwaukee listing asks £95.00 for a three-piece slim set, the highest price in this comparison. The title prints 180 cm, 120 cm and 6 cm, while the bullets print 180 cm, 120 cm and 60 cm, and the file does not resolve that clash. Stated accuracy is 0.029° (0.5 mm/m) in the normal position. The phrase "Accuracy certified by VPA" is printed and not explained. The rating is 4.6 from 221 reviews, and the saved listing has no United Kingdom review text, so you cannot read those stars as British opinion. Magnets, a case and the frame material beyond acrylic vials are not stated, and Included Components prints 1. Confirm the shortest length before you mark a full-height frame.
Pros
States 0.029° (0.5 mm/m) in the normal position
Bullets name 180 cm, 120 cm and 60 cm slim levels
4.6 from 221 reviews
25 mm width listed
Cons
Title says 6 cm where the bullets say 60 cm
No UK review text in the file
Magnets, a case and the frame material are not stated
"Accuracy certified by VPA" is unexplained
Best for: A buyer who wants a slim Milwaukee set and will confirm the shortest length before setting out.
Less suitable: Anyone who needs a settled contents list, magnets or UK review text before paying £95.
The TOUGH MASTER set puts a 250 mm, a 600 mm and a 1,200 mm magnetic level in your hand for £45.99, which covers a fitting, a door and a stud run. Every included length is named as magnetic, and the listing states 0.5 mm/m with vials for 45°, 90° and 180°. Across 170 reviews on the UK listing it sits at 4.4. Reviewers praise the magnets, and some also say the level and plumb vials do not agree, so you still flip-test on arrival. The Number of Items field prints 1 even though three lengths are listed, and neither a bag nor end caps are stated. At 2.3 kg you have no 1,800 mm level for a long wall or a screed. It is the best value here if you want a stated 0.5 mm/m, a magnet on every piece, and more than a handful of reviews, without paying the OX Pro price.
Pros
250 mm, 600 mm and 1,200 mm, each named magnetic
Stated accuracy 0.5 mm/m
Vials for 45°, 90° and 180°
4.4 from 170 reviews at £45.99
Cons
Some UK reviews say the level and plumb vials disagree
Number of Items prints 1
No bag or end caps stated
No 1,800 mm length
Best for: Steel, scaffold and general site jobs where you want a magnetic 250/600/1,200 mm set.
Less suitable: A long wall that needs about 1,800 mm, or work on a non-ferrous surface where the magnets do nothing.
The AB Tools set gives you 10 in, 24 in, 48 in and 72 in aluminium levels plus a storage bag for £40.99. The 72 in piece is about 1,829 mm, the longest span in this comparison, and the listing states 0.5 mm/m. All pieces except the 10 in level are stated to have three vials. Across 296 reviews on the UK listing it sits at 4.3, and UK reviews include bent long levels, so you should sight the 48 in and 72 in soles before you mark a wall. Magnetism is not on the listing. One UK review says the small level is magnetic, which does not make the long pieces magnetic. A bent 72 in sole cannot set out a long run until you return it.
Pros
10 in, 24 in, 48 in and 72 in, the longest piece here
Stated accuracy 0.5 mm/m
Storage bag included
4.3 from 296 reviews at £40.99
Cons
UK reviews include bent long levels
Magnetism is not stated on the listing
The 10 in level is left out of the three-vial line
Best for: A long wall or a full-height frame if the 72 in level arrives straight.
Less suitable: Anyone who cannot return a bent level, or steel work that needs magnets on every length.
The URASISTO five-piece set lists 10 in, 16 in, 24 in, 32 in and 48 in aluminium levels at £56.99, so you can move from a short fitting up to about 1,219 mm. The title states a magnetic torpedo, and it does not say the other four lengths are magnetic. The bullets state 45°, 90° and 180° vials, plastic shock-absorbing ends and a carry bag. The UK listing shows 4.3 from 181 reviews. The accuracy line claims 0.0005 inch/ft, which is not a result measured for this comparison, so you should check the bubble both ways. You do not get a 72 in piece for a long wall. You also pay more than the three-piece URASISTO listing for the extra 16 in and 32 in lengths.
Pros
Five lengths from 10 in to 48 in
Magnetic torpedo stated, with 45°, 90° and 180° vials
Carry bag and shock-absorbing ends stated
4.3 from 181 reviews
Cons
The other four lengths are not stated as magnetic
0.0005 inch/ft is not a measured result here
No 72 in length
£56.99, above the three-piece URASISTO set
Best for: Home jobs that need several inch lengths up to 48 in and a magnetic torpedo.
Less suitable: Steel work that needs every piece magnetic, or a run longer than about 1,200 mm.
The Firecore set is four box-beam levels at 25 cm, 30 cm, 60 cm and 120 cm, with a nylon bag, at £69.99. You can check a short fitting and a door-height run, and the listing states ±0.5 mm/m with horizontal, vertical and 45° vials. Rubberised shockproof end caps and handles are stated. Across 58 reviews on the UK listing it sits at 4.3. The bullets put a magnetic base on the torpedo only, and reviews disagree on whether every length is magnetic, so you should not treat it as a fully magnetic set. At 2.11 kg the box section is the stiffer frame shape named here. You still have no 1,800 mm level, and £69.99 sits in the premium band for a magnet story that is clear only on the 25 cm piece.
Pros
Box-beam lengths at 25 cm, 30 cm, 60 cm and 120 cm
Stated accuracy ±0.5 mm/m
Nylon bag, rubberised caps and handles
Horizontal, vertical and 45° vials
Cons
Magnet stated on the torpedo only
Reviews disagree on whether every length is magnetic
58 reviews, and no 180 cm piece
£69.99 for that magnet limit
Best for: DIY and carpentry where you want a boxed 120 cm set, a short torpedo and a bag.
Less suitable: Steel work that needs every piece magnetic, or a long wall that needs about 1,800 mm.
The listing states 120 cm, 60 cm, 30 cm and 25 cm, four box-beam pieces, with a nylon bag.
Are all four levels magnetic?
The bullets state a magnetic base on the torpedo level. The title says magnetic bubble level tools. Whether every length is magnetic is not stated on the listing.
What accuracy is stated?
±0.5 mm/m is stated. Horizontal, vertical and 45° vials are stated, with rubberised shockproof end caps.
The Silverline set is three aluminium builders levels at 400 mm, 600 mm and 1,000 mm, model 119688, for £25.40. That is the lowest price here, and the UK listing shows 4.2 from 2,930 reviews. An accuracy figure in mm/m is not on this listing, and magnets and a bag are not stated, so you cannot treat it as a 0.5 mm/m magnetic set. Item weight is printed as 0.76 g, which the file leaves as printed and which cannot be the real mass of three levels. The lengths stop at 1,000 mm, a different ladder from a 600 mm and 1,200 mm pair, and you have nothing near 1,800 mm. A one-year warranty is stated. Use this set for light home marking only after you flip-test it, and return it if a sole is bent.
Pros
£25.40 for 400 mm, 600 mm and 1,000 mm
4.2 from 2,930 reviews
One-year warranty stated
Metric lengths on the listing
Cons
Accuracy in mm/m is not on the UK listing
Magnets and a bag are not stated
Printed weight of 0.76 g is not a credible mass
No 1,200 mm or 1,800 mm piece
Best for: Light DIY, such as shelves or a shed base, if the levels pass a flip test.
Less suitable: Site work that needs a stated 0.5 mm/m, magnets or a 1,200 mm level.
The OX Trade twin pack is a 600 mm and a 1,200 mm aluminium pair at £39.99, the two lengths most second-fix work actually uses. The listing states 0.5 mm/m, a fine milled base, dual easy-view vials, shock-absorbing rubber end caps and a lifetime warranty on the vials. It weighs 1.5 kg. The UK listing shows 4.2 from four reviews, which is too small a sample to treat as a quality verdict, including a Spirit Levels rank of 1. The bullets say OX Pro Tuff while the item type name says Trade, so you should match model OX-T439704-E before you assume which level is in the box. Magnetism, a carry bag and the profile size are not stated. You also get no torpedo and no 1,800 mm level.
Pros
600 mm and 1,200 mm at a stated 0.5 mm/m
Fine milled base and dual easy-view vials
Lifetime vial warranty stated
£39.99 and 1.5 kg
Cons
Only four reviews
Bullets say OX Pro Tuff while the item type name says Trade
Magnet, bag and profile size are not stated
No torpedo and no 1,800 mm length
Best for: A 600 mm and 1,200 mm pair if you will flip-test and you do not need a large review sample.
Less suitable: Anyone who wants review volume before trusting a level, or who needs magnets, a bag or a third length.
The listing states a twin pack of 600 mm and 1200 mm. Stated accuracy is 0.5 mm/m (0.005 in/in).
Is the set magnetic?
Magnetism is not stated. A fine milled base and shock-absorbing rubber end caps are stated.
What warranty is stated?
The bullets state a lifetime warranty on the vials. A carry bag is not stated.
How we compared
Nine amazon.co.uk listings are on this page. Length, stated accuracy and frame were checked across a wider set of listings before this shortlist. There is no separate score sheet and no laboratory test. The top pick and the best value follow the awards already stored on the URASISTO three-piece and Tough Master listings. A higher star line is not treated as a truer vial when the UK review text is thin.
1
Lengths you will use
25%
A torpedo near 250 mm, a 600 mm level and a 1,200 mm level cover most second-fix work. About 1,800 mm is for a long wall, a screed or a full-height frame. A 400 mm or 1,000 mm set is a different ladder.
2
Stated accuracy
25%
Prefer a listing that prints 0.5 mm/m in the normal position, then flip the level on the same marks. A tighter printed line is still only a sentence until the bubble agrees both ways.
3
Frame
20%
A closed box section is the stiffer trade shape. If you can bend the extrusion in your hands, it is a poor bet on site. A milled sole is useful and secondary.
4
Vials
15%
You need vials you can see, including plumb. Read from above the vial so parallax does not fake a centre. Level and plumb should agree when you turn the level 180°.
5
Magnet and extras
15%
A magnet is for ferrous steel only, and the sole must still sit flat. A magnetic title does not prove every piece has a magnet. A bag and shock caps are useful, and they come after the lengths.

Spirit level set buying guide
Length decides the set before price does. A torpedo near 250 mm, a 600 mm level and a 1,200 mm level cover most second-fix work. About 1,800 mm is for a long wall, a screed or a full-height frame. After length, read the stated tolerance and plan to flip-test it. A closed box is the stiffer frame. A magnet is for ferrous steel only, and a magnetic title does not cover every piece. A bag, shock caps and a milled sole are useful and secondary.
What is a spirit level set?
A spirit level set is two or more bubble levels in one buy. You use it so a short fitting and a longer run are not forced onto one sole. In the United Kingdom the useful trade figure printed on better listings is 0.5 mm/m in the normal position: up to about half a millimetre of error over one metre, if the level is actually at that tolerance. Nothing on this page is a laboratory test. Shelf prices are the figures stored from amazon.co.uk, in GBP.
Lengths come first.
Best for
Home shelves and short fittings if you will flip-test a light set
Site work that needs a stiff 600 mm and 1,200 mm level at a stated 0.5 mm/m
Not ideal for
Steel work if the listing does not put a magnet on every length
Scaffold inspection, a drain fall, or setting-out you cannot check yourself
Mistakes to avoid
1
Buying lengths you will not use
A 400 mm or 1,000 mm trio is a different ladder from 600 mm and 1,200 mm. A 72 in level is for a long wall or a full-height frame. If you will not use it, you are paying for a sole that stays in the bag.
2
Trusting a printed accuracy with no flip test
0.5 mm/m is a listing claim until you turn the level 180° on the same marks and the bubble agrees. A tighter inch-per-foot line is still only a sentence. Stars do not replace that check.
3
Assuming every piece is magnetic
A magnetic title, or a magnetic torpedo line, does not put a magnet on every length. The sole still has to sit flat. Magnets do nothing on timber, copper, plastic or most stainless steel.
What to weigh up
Lengths you will use
High
Match the lengths to the jobs you actually do. A torpedo near 250 mm, a 600 mm level and a 1,200 mm level cover most second-fix work. About 1,800 mm is for a long wall or a full-height frame. A 400 mm or 1,000 mm set is a different ladder from a 600 mm and 1,200 mm pair.
Tough Master is 250 mm, 600 mm and 1,200 mm. OX Trade and OX Pro are 600 mm and 1,200 mm only. Firecore is 25 cm, 30 cm, 60 cm and 120 cm. Silverline stops at 400 mm, 600 mm and 1,000 mm.
Stated accuracy and frame
High
Prefer a listing that prints 0.5 mm/m in the normal position, then flip-test on arrival. That figure is about half a millimetre over one metre, and only if the level is actually at that tolerance. Tough Master, AB Tools, OX Trade, Firecore, OX Pro and Milwaukee print a 0.5 mm/m claim. Milwaukee also prints 0.029°, and the phrase “Accuracy certified by VPA” is not explained. The Silverline amazon.co.uk listing does not print mm/m.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
🏠
Home shelves and short fittings
You want a light set for shelves, a kitchen or a shed base, and you will flip-test it. The URASISTO three-piece set is the top pick: 12 in, 20 in and 40 in at £35.99, with 4.8 from 391 reviews. The stored file has only four short UK reviews, and there is no 48 in piece.
You want a stiff 600 mm and 1,200 mm pair at a stated 0.5 mm/m, and you will sight the sole before you mark. The OX Pro set is a 66 mm by 30 mm box with a fine-milled top and bottom, at £82.99. The bullets do not call it magnetic, and there is no torpedo.
You want a magnet on every length, not only in the title, and a stated 0.5 mm/m. The Tough Master set is the best value: 250 mm, 600 mm and 1,200 mm, each named magnetic, at £45.99, with 4.4 from 170 reviews. Some UK reviews say the vials disagree, so flip-test it. There is no 1,800 mm piece.
The top pick is the URASISTO three-piece set: 12 in, 20 in and 40 in, listed at £35.99. amazon.co.uk shows 4.8 from 391 reviews, the highest star line in this table. The stored file has only four short UK reviews, so that average is a thin UK sample, not a laboratory result. The title states magnetic torpedo levels. The listing claims 0.0005 inch/ft, which was not measured here. There is no 48 in or 72 in piece. Flip-test the vials before you fit a shelf or a door.
How much does a spirit level set cost on amazon.co.uk?
Stored amazon.co.uk shelf prices, not a live basket, put entry sets at about £25 to £36. That band is the Silverline 400/600/1,000 mm set at £25.40 and the URASISTO 12/20/40 in set at £35.99. Mid-price sets run from about £40 to £57: OX Trade at £39.99, AB Tools at £40.99, Tough Master at £45.99 and the URASISTO five-piece at £56.99. Premium sets run from about £70 to £95: Firecore at £69.99, OX Pro at £82.99 and Milwaukee at £95.00. A higher price is not a measured accuracy.
What should I check before I buy a spirit level set?
Choose lengths you will use before you compare stars. A torpedo near 250 mm, a 600 mm level and a 1,200 mm level cover most second-fix work. Add about 1,800 mm only for a long wall, a screed or a full-height frame. Then look for a stated 0.5 mm/m and plan a flip test on the same marks. Prefer a closed box you cannot bend in your hands. Read the vials from above. Buy magnets only for ferrous steel, and do not assume every piece in the box has one.
How do I check a spirit level set is true?
Mark both ends on a flat surface and note where the bubble sits when you look square on. Turn the level 180° on the same marks. The bubble should agree. Do the same for the plumb vial. A printed 0.5 mm/m, or a tighter inch-per-foot line, is still only a sentence until that check passes. If a new level is bent, or the bubble does not agree, reject or return it under the Consumer Rights Act 2015. Do not fit a kitchen with it.
Is 0.5 mm/m a British Standard for a spirit level?
No. No British Standard in the sources used here makes 0.5 mm/m a legal limit for a consumer spirit level. The figure means up to about half a millimetre of error over one metre, and only if the level is actually at that tolerance. Stabila prints ±0.50 mm/m in the normal position and ±0.75 mm/m overhead for the Type 96-2, with 0.029° as the degree form of 0.5 mm/m. Do not copy the overhead figure onto other brands. The 1986 linear-measure regulations are not a bubble-level specification.
Does magnetic mean every level in the set is magnetic?
No. A magnetic title, or a magnetic torpedo line, does not prove every length has a magnet. On the listings here, Tough Master names all three included levels as magnetic. URASISTO states a magnetic torpedo, and the other lengths are not stated as magnetic. Firecore’s bullets put a magnetic base on the torpedo only, and reviews disagree on the other lengths. OX Pro’s bullets do not say magnetic. The sole still has to sit flat. Magnets do nothing on timber, copper, plastic or most stainless steel.
When is one spirit level enough instead of a set?
Buy a set when you need more than one length in the same job, such as a short fitting and a door or a stud. One spirit level is enough when every mark you make is the same span. A 600 mm level cannot check a long wall, and a torpedo cannot plumb a door. If you only need a single length, use the spirit level comparison. For steel, a magnet belongs on the length you will actually stick to the work, not only in the product title.
When should I call a professional instead of trusting the set?
Call a professional for structural setting-out you cannot check, for scaffold inspection, for drainage falls you are not equipped to prove, and for work at height that needs protection rather than a longer vial. A scaffold magnet is not a scaffold inspection. Do not stand on a level. A bubble does not make an installation compliant, and this comparison did not test falls or structures. If a new level arrives bent, return it rather than working around the sole.
Our verdict
The top pick is the URASISTO three-piece set at £35.99, with 12 in, 20 in and 40 in levels and 4.8 from 391 reviews. The stored file has only four short UK reviews, the accuracy line claims 0.0005 inch/ft, and there is no 48 in or 72 in piece. Best value is the Tough Master 250 mm, 600 mm and 1,200 mm set at £45.99, with 0.5 mm/m stated, a magnet named on every piece, and 4.4 from 170 reviews. Some UK reviews say those vials disagree, and there is no 1,800 mm level. For a stiff milled pair, the OX Pro 600 mm and 1,200 mm set is £82.99 and is not stated as magnetic.
Best overall
URASISTO 3-piece spirit level set
Top pick for shelves and short fittings: 12 in, 20 in and 40 in at £35.99, with 4.8 from 391 reviews, once you have flip-tested a thin UK review sample.
