Patio pots
You are filling large pots, where a 60 litre multi-purpose bag matches the use the RHS gives potting compost. Growmoor 60 litres has the longest review file here, and the title and the spec both say 60 litres. It does not say peat-free.
Raised bed compost comparison 2026
The best raised bed compost bags, compared.
Top pick: Munnie multi-purpose compost 60 L Best value: Munnie multi-purpose compost 60 L – Lowest shelf price at about £9.34, about £0.16 a litre, with 4.6 from 2,045 reviews. The peat bullet is a reduction sentence, and the pack count is 2. Updated October 2026.
Raised bed compost is the bag many UK gardeners look for when a bed looks short of organic matter. The Royal Horticultural Society still wants most of a new bed to be topsoil, with compost as the smaller share, because potting compost slumps if it is the whole fill. None of the titles says raised bed compost or peat-free. You tell them apart by litres, price per litre, and whether the bullets name a bed. A 1.2 × 0.6 × 0.30 m bed is about 216 litres. At three parts in twelve, the compost share is about 54 litres, so one 60 litre bag covers that share and little more. Read [how compost sits on a raised bed](/hub/raised-beds-greenhouses-and-compost/blog/compost-on-raised-beds) before you treat any bag as a full bed mix. Raised bed compost, as UK shoppers search for it, is the bag you hope will fill or top up a raised bed. The Royal Horticultural Society tells you to fill most beds with seven parts topsoil, three parts organic matter and two parts horticultural sharp sand. Organic matter here means garden compost, leafmould, or well-rotted manure. On paving, the sand share rises to four parts.

The best raised bed compost bags in detail
Our view
Munnie's listing is a 60 litre multi-purpose compost at £9.34, about £0.16 a litre, the lowest shelf price in this set. amazon.co.uk shows 4.6 from 2,045 reviews. The bullets name vermiculite, plant nutrients, and wetting agents, and they cover seed sowing plus indoor and outdoor crops. They also say the blend helps by enabling the reduction of the use of peat, which is not the same as peat-free. The title and the volume field say 60 litres, while the number of packs is 2, and the unit count of 60,000.0 gram does not match the 14.9 kg weight. No bullet names a raised bed. It is the best value when you want a cheap 60 litre bag for pots or a small top-up and you will read that peat sentence as a reduction claim only.
Pros
- £9.34, about £0.16 a litre, the lowest shelf price here
- 4.6 from 2,045 reviews
- Vermiculite, nutrients, and wetting agents named
- Seeds, indoor plants, and outdoor crops named
Cons
- Peat wording is a reduction claim, not peat-free
- Pack count is 2 on a 60 litre title
- 14.9 kg against a unit count of 60,000.0 gram
- Raised beds are not named
Best for: Pots, seed sowing, and a small top-up when the price per litre is the reason to buy.
Less suitable: A bag that must say peat-free, or a listing that names raised beds.

Common questions
Does Munnie say this bag is peat-free?
No. The bullet says the blend benefits the environment by enabling the reduction of the use of peat. It does not say peat-free.
Is the pack count the same as the title volume?
The title and the volume field say 60 litres. The number of packs is 2. The item weight is 14.9 kg and the unit count is 60000.0 gram.
What does the listing say it can be used for?
Indoor and outdoor plants, vegetables, fruit, flowers, herbs, shrubs, trees, seed starting, and potting indoor plants.

TerraGrade is a 60 litre multipurpose compost at £10.99, and it is the only listing here whose bullets name raised beds. amazon.co.uk shows 4.6 from 493 reviews. The title volume and the spec both say 60 litres, and the 14.9 kg weight matches the unit count of 14,900.0 gram. The bullets say to blend it with quality topsoil for delicate seeds, and they do not say peat-free, even though one review calls it peat-free. The brand field is ecoblaze while the title says TerraGrade, and the manufacturer line is Zebra Renewables Ltd in Perivale. It suits a 60 litre top-up where the bullet actually says raised beds, and it is a weaker match if you need a peat-free mark or a review file the size of Growmoor's.
Pros
- Bullets name raised beds, borders, and garden beds
- 60 litre title and spec agree; 14.9 kg matches 14,900.0 gram
- 4.6 from 493 reviews
- Seeds and seedlings named, with a topsoil blend for delicate seeds
Cons
- Does not say peat-free
- Brand field is ecoblaze, not TerraGrade
- 493 reviews, the smallest count in this set
Best for: A single 60 litre top-up when the listing must mention raised beds.
Less suitable: A peat-free purchase, or delicate seeds used straight from the bag.

Common questions
Does the listing mention raised beds?
Yes. One bullet names raised beds, borders, and garden beds, and another names beds and borders with containers and hanging baskets.
What brand name is on the listing?
The title uses TerraGrade. The brand name field is ecoblaze. The manufacturer is Zebra Renewables Ltd, Europa House, Perivale, London UB6 7JD.
Does this listing say the compost is peat-free?
No. The bullets do not say peat-free. For delicate seeds they say to blend it with quality topsoil.
Our view
The Growmoor 60 litre bag is a single multi-purpose compost at £13.98, with the title and the volume field both saying 60 litres. amazon.co.uk shows 4.5 from 7,425 reviews, the largest count in this set. The bullets name seeds, cuttings, containers, and garden beds and borders, and they say the mix supplies nutrients for roots. The listing does not say peat-free, and one review thinks the bag contains peat, which is a comment rather than a label. The item weight is 14 kg while the unit count is printed as 60,000.0 gram, so those two figures do not agree. At about £0.23 a litre it is the dearest bag here. It is the top pick when you want one 60 litre bag with a long review history for pots or a bed top-up, not a peat-free raised-bed mix.
Pros
- Title and spec both say 60 litres
- 4.5 from 7,425 reviews, the largest count in this set
- Bullets name seeds, cuttings, containers, and garden beds and borders
- Country of origin field says United Kingdom
Cons
- Does not say peat-free
- 14 kg against a unit count of 60,000.0 gram
- About £0.23 a litre, the highest in this set
Best for: Containers, seeds, and a bed-and-border top-up when you want the longest review history in this set.
Less suitable: A whole raised bed, a peat-free label, or the lowest price per litre.

Our view
The Growmoor twin listing is titled 2 × 60 L at £21.71, with two packs and a weight of 22 kg, while the volume field says 60 litres. amazon.co.uk shows 4.4 from 3,611 reviews. The bullets name flowering, potted plants, flower beds, and added nutrients. They do not say peat-free, and they do not name seeds. If you price the title as 120 litres, the bag is about £0.18 a litre; the 60 litre spec field would change that sum. Reviews include a missing second bag, split bags, and a different brand arriving in place of Growmoor. It is a flower-bed order only when both bags match the Growmoor volume on the title.
Pros
- Title says 2 × 60 L, two packs, 22 kg
- 4.4 from 3,611 reviews
- Bullets name flower beds, pots, and added nutrients
- About £0.18 a litre if the title volume is 120 litres
Cons
- Spec volume says 60 litres on a 2 × 60 L title
- Does not say peat-free, and does not name seeds
- Reviews include a missing second bag, split bags, and a different brand
Best for: Flower beds and pots when you can check that both bags are the Growmoor volume the title names.
Less suitable: A peat-free label, seed sowing, or an order you cannot inspect on arrival.

Our view
The Growmoor 180 litre listing is titled as 3 × 60 L bags at £30.00, and the spec volume also says 180 litres, so the two volume lines agree. amazon.co.uk shows 4.4 from 767 reviews. Three packs are listed and no item weight is shown. The form field says granules, and the best-sellers line also sits in Compost & Yard Waste Containers, which does not make this a compost bin. The bullets name added nutrients, flower beds, potted plants, and all gardens, and they do not say peat-free. Reviews include missing bags, bags arriving on different days, split packaging, and compost that stays dry so water sits on top. At about £0.17 a litre it is a larger flower-bed and pot order only when all three bags arrive intact.
Pros
- Title and spec both say 180 litres, as 3 × 60 L
- 4.4 from 767 reviews
- Bullets name flower beds, potted plants, and added nutrients
- About £0.17 a litre on the title volume
Cons
- No item weight is shown
- Does not say peat-free
- Reviews include missing bags, split packaging, and compost that stays dry so water sits on top
- Form field says granules; the rank also sits in Compost & Yard Waste Containers
Best for: Flower beds and pots when you want three 60 litre bags and can check that all three arrive.
Less suitable: A peat-free bed mix, or an order where a short or split delivery would leave the bed short.

Our view
Laeto is the largest title in this set, 240 litres at £41.63, with the spec volume also saying 240 litres. amazon.co.uk shows 4.3 from 1,858 reviews, the lowest star line here. The bullets describe a blend of topsoil and soil improver, enriched with nutrients, for house plants, vegetables, herbs, flowers, and seed sowing, and they name rose beds. They do not answer the page question about whether it is peat-free. No item weight is shown, and the unit count is 240,000.0 gram. Several reviews report a strong farmyard or manure smell, and one review reports mildew, a glass shard, plastic, and a lot of wood, which is one report rather than a fault of the brand. At about £0.17 a litre it is a large multi-purpose bag for pots and rose beds, not a BS 3882 topsoil.
Pros
- Title and spec both say 240 litres, the largest volume here
- 4.3 from 1,858 reviews
- Bullets name rose beds, house plants, vegetables, and seed sowing
- Described as topsoil plus soil improver, still a compost listing
Cons
- Peat-free is asked on the page and not answered in the bullets
- No item weight; unit count is 240,000.0 gram
- Several reviews report a farmyard or manure smell
- One review reports mildew, a glass shard, plastic, and wood
Best for: House plants, pots, and rose beds when you want one 240 litre multi-purpose bag.
Less suitable: A peat-free label, a BS 3882 topsoil order, or a bag you would use without tipping it out to look first.

Raised bed compost buying guide
You are choosing a bag of multi-purpose compost, not a tested raised-bed soil. Start with the job: pots, a top-up, or the organic share of a new bed. Then match litres to a measurement, read whether the listing names a bed, and reject a peat-free hope that the bag does not print. Price per litre uses the title volume. Where the spec field disagrees, treat the order as unchecked until the bags arrive. The six listings below are the whole set on this page. No score here is a laboratory result.
What is raised bed compost?
Raised bed compost, as UK shoppers search for it, is the bag you hope will fill or top up a raised bed. The Royal Horticultural Society tells you to fill most beds with seven parts topsoil, three parts organic matter and two parts horticultural sharp sand. Organic matter here means garden compost, leafmould, or well-rotted manure. Keep potting compost for pots, because it slumps if you use it as the whole bed. On paving, the sand share rises to four parts.
Best for
- Patio growers filling large pots with a 60 litre multi-purpose bag
- Gardeners using compost as the smaller share of a new bed
Not ideal for
- Anyone who needs the words peat-free printed on the bag
- Filling the full depth of a vegetable bed with multi-purpose compost
Mistakes to avoid
- 1
Filling the whole depth with multi-purpose compost
A new bed wants mostly soil. The RHS keeps potting compost for pots because it slumps. Compost is the organic share, a top-up, or a container fill.
- 2
Reading a peat-reduction sentence as peat-free
Munnie's bullet says the blend helps by enabling the reduction of the use of peat. That is not peat-free. If the bag does not say peat-free, the RHS says it likely is not.
- 3
Ignoring a 60 litre field on a 2 × 60 litre title
Growmoor's twin listing is titled 2 × 60 litres and prints a volume field of 60 litres, with two packs and 22 kg. Check the bags on arrival. Goods must match the description.
What to weigh up
Material job and litres
HighA new bed wants mostly soil. Compost is the smaller organic share, a top-up, or the fill of a pot. Do not buy multi-purpose compost as if it were a soil-based raised bed mix. The RHS fill is seven parts topsoil, three parts organic matter and two parts horticultural sharp sand. On a hard surface the sand share rises to four parts. Organic matter means garden compost, leafmould, or well-rotted manure. The bags here are multi-purpose compost.
Label, peat wording and price
HighThe words on the bag decide the peat question. Peat-free must be explicit. A sentence about enabling the reduction of the use of peat is not peat-free. If the bag does not say peat-free, the RHS says it likely is not. None of these six titles says peat-free, and none is scored as PAS 100 or BS 3882. TerraGrade is the only listing whose bullets name raised beds. Growmoor names garden beds, flower beds, or borders. Laeto names rose beds. Munnie does not name a bed.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Bed top-up
You want a 60 litre top-up and the listing should actually name raised beds. TerraGrade is the only bag here whose bullets do that, and it tells you to blend it with topsoil for delicate seeds. It does not say peat-free.
Lowest price per litre
You want the cheapest 60 litre bag in this set for pots or a small top-up. Munnie is about £9.34, about £0.16 a litre. Read the peat bullet as a reduction claim, and note that the pack count is 2.
Common questions about raised bed compost bags
What is the top pick for raised bed compost in 2026?
The top pick on this page is Growmoor multi-purpose compost 60 L, about £13.98. On 16 October 2026 amazon.co.uk showed 4.5 from 7,425 reviews, the largest count here, and the title and the volume field both say 60 litres. The bullets name seeds, containers, and garden beds. It does not say peat-free, and at about £0.23 a litre it is the dearest bag here. Use it for pots or a bed top-up, not to fill a whole raised bed.
How much does raised bed compost cost?
On 16 October 2026 the six amazon.co.uk prices ran from about £9.34 to about £41.63. Munnie's 60 litre bag was about £0.16 a litre. TerraGrade was about £10.99, about £0.18 a litre. Growmoor 60 litres was about £13.98, about £0.23 a litre. Growmoor 180 litres was about £30.00 and Laeto 240 litres was about £41.63, both about £0.17 a litre. These are shelf prices from that date.
What should you check before you buy raised bed compost?
Measure the bed and treat compost as the smaller share, not the whole fill. Litres are length times width times depth in metres, times 1,000. Check that the title volume matches the spec, that peat-free is actually printed, and what the bag weighs if you must carry it. The frame is a separate buy: see the raised bed comparison. None of these six listings is a BS 3882 topsoil.
Is any bag in this comparison peat-free?
No bag in this set says peat-free. Munnie's bullet says the blend helps by enabling the reduction of the use of peat. That is a reduction sentence, not a peat-free label. The RHS says that if a bag does not say peat-free, it likely is not. A retail ban was announced on 27 August 2022 for 2024 and has not been enacted. A Defra answer of 19 March 2026 says legislation waits on parliamentary time.
How many litres of compost does a raised bed need?
A 1.2 × 0.6 × 0.30 m bed holds about 216 litres. The RHS mix is seven parts topsoil, three parts organic matter and two parts horticultural sharp sand, so the compost share is about 54 litres. On paving the sand share rises to four parts. One 60 litre bag can cover that compost share. It does not fill the bed. Work the sum for your own length, width and depth before you order a 180 or 240 litre pack.
Can you fill a whole raised bed with multi-purpose compost?
Do not fill the whole depth with multi-purpose compost. The RHS says soil should be the main fill because potting compost slumps, and it tells you to keep potting compost for pots. Compost is the organic share, a top-up, or the fill of a container. A raised bed mix of screened topsoil plus compost is a different product and is not in this set. If you need a bulk load, ask for a BS 3882:2015 declaration of analysis.
What if the title volume and the spec disagree?
Growmoor's 2 × 60 litre listing, about £21.71, prints a volume field of 60 litres, a weight of 22 kg, and two packs. Priced as 120 litres it is about £0.18 a litre. The 60 litre field would change that. Consumer Rights Act 2015 section 11 says goods must match the description, so check the bags on arrival. Reviews include a missing second bag, split bags, and a different brand. That does not mean every Growmoor order is substituted.
Should one bad review rule out a compost brand?
Several Laeto reviews report a farmyard or manure smell, and one review reports mildew, a glass shard, plastic and wood. That is one debris report, not a reason to call the brand unsafe. Tip a bag out and look before you use it around hands or food crops. Use a specialist when you need a BS 3882 declaration on bulk topsoil, when the offer is waste-derived soil under RPS 190, or when the ground may be contaminated.
Our verdict
These six bags are multi-purpose compost, not a peat-free raised-bed mix and not a BS 3882 topsoil. For one 60 litre bag with a long review history, for pots or a bed top-up, the top pick is Growmoor 60 litres at about £13.98. It is also the dearest per litre. If the shelf price matters more, the best value is Munnie at about £9.34, and you should read its peat sentence as a reduction claim. If the bullets must name raised beds, that is TerraGrade, which has no award on this page.
