Build a Raised Bed for Under £10 UK

The cheapest raised bed for sale in a UK garden centre in 2026 is around £85 for a 1m by 1.2m kit in untreated softwood. The same bed in pressure-treated planks at the same size costs £125 to £140. Most UK gardeners building five raised beds for a new allotment plot would face a £600 to £700 bill before a single seed went in.

This guide shows how to build the same 1m by 2m bed for under £10 in materials. We have done it 28 times across 11 years in Staffordshire. The reclaimed wood is free or near-free. The screws and corner stakes cost under £4. The build takes 35 to 50 minutes per bed with a cordless drill.

Materials list (£8.40 - £9.80)

For a single 1m by 2m raised bed at 200mm depth.

The screws are the only item you must buy new. A box of 200 80mm exterior screws costs £3.40 to £4.50 from Screwfix or Toolstation, enough to build 12 to 13 beds. Cordless drill and screwdriver bits required but assumed already owned.

Reclaimed scaffold boards from a local scaffolder. Look for 38mm thick boards (UK standard), 225mm wide, lengths of 3.9m or 2.4m. One 3.9m board cuts into two 2m bed lengths.

Where to get free wood

Five reliable sources for free or near-free reclaimed wood in the UK.

1. Local scaffolding companies (best source)

UK scaffold boards are graded for safety. Boards with splits, knots over 25mm, or end-cracks are condemned and removed from circulation. The scaffolder typically pays a disposal cost to remove them. Many will give them to you free if you collect.

Ring three local scaffolders. Ask for “rejected boards” or “Grade-1 condemned.” Typical board is 3.9m long, 38mm thick, 225mm wide, in untreated softwood. One board cuts into the four sides of a 1m by 1m bed, or two long sides of a 1m by 2m bed.

2. Construction skips

Always ask the property owner first. Builders regularly throw out short offcuts, broken pallets, and unwanted decking that is structurally fine but visually rejected. A polite question yields wood about 60% of the time in our experience.

3. Pallet wood

Pallets are 25mm thick (compared to 38mm scaffold). They are shorter (1.2m typical) and weaker. They last 3 to 5 years vs 6 to 8 for scaffold. But they are everywhere - any industrial estate has a daily surplus.

Warning: Only use pallets stamped “HT” (heat-treated). Pallets stamped “MB” (methyl bromide) have been chemically fumigated and are unsuitable for vegetable beds. Most modern UK pallets are HT.

Check every pallet for the IPPC stamp. HT (heat-treated) and KD (kiln-dried) are safe for vegetable beds. MB (methyl bromide) is not safe and is illegal to use.

4. Freecycle and local Facebook groups

The “Freecycle Network” and local “Free Stuff” Facebook groups regularly list raised bed materials. Filter by “wood” or “timber” weekly. Most listings are collection only and require a car or van.

5. Olio app

A community surplus app increasingly popular in UK suburbs. Search the “Stuff” listings for wood, timber, or planks. Pickups are usually within 2 to 5 miles.

The build (35-50 minutes)

The whole build assumes you have already collected the wood and have a cordless drill. Allow 35 minutes for the first build and 25 minutes once you have done a few.

Step 1: cut the wood (5 minutes)

Cut the boards to two 2m lengths (long sides) and two 1m lengths (short sides). Cut the corner stakes to 400mm each, with one end pointed for easier driving into soil.

A handsaw works fine. A circular saw or jigsaw is faster. The cuts do not need to be precise to the millimetre - the boards bed in to the soil and the corner posts hide rough ends.

Step 2: mark the site and clear (5 minutes)

Mark a 1m by 2m rectangle on the ground with string and four bamboo canes. Pull up any couch grass or perennial weeds within the footprint. Skim the surface but do not dig deeper than 50mm.

Step 3: lay the cardboard (5 minutes, optional)

Flatten two large cardboard boxes and lay them inside the marked rectangle. Wet the cardboard with a watering can. This suppresses weeds for 6 to 8 months while the bed establishes, then breaks down into the soil.

Step 4: drive the corner stakes (5 minutes)

Drive each 400mm stake into the ground at each corner of the rectangle. The pointed end goes down. Leave 250mm of stake above ground. Use a club hammer or the back of a hammer. Aim for vertical (use a spirit level on the side if you have one, eyeball if not).

Step 5: screw the boards to the stakes (15 minutes)

Stand one of the 2m boards against the two corner stakes on the long side. Hold the board flush with the top of the stake. Drill two 80mm screws through the board into each stake, near the top and bottom.

Repeat for the other long side. Then the two short sides. Each side uses 4 screws (2 per stake). Total 16 screws.

Step 6: check and fill (10 minutes)

Check the bed is roughly square (measure the diagonals - they should be within 30mm of each other). Fill with topsoil, compost, leaf mould, or a 50:30:20 mix.

Driving 80mm exterior screws through the board into a corner stake. Four screws per stake, 16 in total for a 1m x 2m bed. Total build time 35-50 minutes.

Filling the bed

A 1m by 2m bed at 200mm depth holds 0.4 cubic metres of soil. The cheapest sourcing options for UK gardeners.

The no-dig method works particularly well in a budget raised bed. Lay cardboard, then 100mm of well-rotted horse manure (often £0-£10 from local stables on Facebook Marketplace), then 100mm of leaf mould or council compost. The bed is ready to plant within 4 weeks.

Tip: Most local councils sell composted green waste at £30-£50 per cubic metre. Search “[your council] green waste compost” or “Pro Grow” online. Bulk pickup beats bagged compost from garden centres by 70% on cost.

Durability test: 6 years of UK weather

Across 28 builds since 2014 in Staffordshire, the durability data is consistent.

The single biggest extension to bed life is to raise the boards 25mm off the soil on brick offcuts or roofing slates. This stops the prolonged ground contact that rots untreated softwood. The trick adds two to three years to the life of scaffold boards at no cost.

Lining: cardboard yes, plastic no

The most over-engineered part of any “how to build a raised bed” advice is the lining.

Use cardboard or newspaper. Lay 2-3 layers under the bed before filling. Suppresses weeds. Breaks down in 6-9 months into the soil. Costs nothing.

Do not use plastic weed membrane. Restricts drainage. Stops worm and beneficial insect movement. Decays into microplastic within 5 years. Adds £8-£15 per bed for no benefit.

Do not use plastic sheeting along bed sides. Some builds add plastic between board and soil “to protect the wood.” This holds moisture against the wood and rots it faster, not slower. Skip it.

Comparison: budget vs shop-bought raised beds

The DIY scaffold board bed is the lowest cost per year of all. The hardwood bed lasts longest but costs 20 times more to install.

The completed 1m x 2m bed filled with a no-dig lasagne mix of cardboard, manure and leaf mould. Total cost £8.40 in materials, ready to plant within four weeks.

A typical UK allotment plot with five scaffold-board beds built over a single weekend. Total materials cost across all five beds: £42.

What to grow in a 1m x 2m raised bed

A bed this size suits one of the following first-year plans.

Plan 1: salad and herb bed

• 8 lettuce (curly oak leaf, lollo rosso)
• 6 spring onions
• 4 radish patches sown weekly through summer
• 4 dwarf French beans
• 2 climbing French beans on canes
• Border of basil and parsley

Plan 2: root vegetable bed

• 2 rows carrots
• 1 row beetroot
• 1 row spring onions
• 1 row turnips
• 1 row parsnips (slow but high value)

Plan 3: brassica bed

• 4 broccoli
• 4 cabbages
• 2 cauliflower
• 6 kale plants

Plan 4: mixed kitchen garden

• 2 tomato plants (south end)
• 4 lettuce
• 1 row carrots
• 6 spring onions
• 4 dwarf French beans
• Basil and parsley around edges

Yield in year one runs to 25-50kg of produce depending on the plan. The £8.40 raised bed pays for itself in produce within the first growing season.

Common mistakes when building a budget raised bed

Mistake 1: choosing thin pallet wood for a long bed

A 3m bed built from 25mm pallet wood bows outward within two years from soil pressure. Either use scaffold boards (38mm), or add a centre brace to a long pallet bed at 1.5m spacing.

Mistake 2: not raising the boards off soil

Continuous ground contact rots untreated softwood twice as fast as raised boards. Always sit the bed on a row of brick offcuts, slate, or even half-buried roofing tiles. Adds zero cost for two to three years of extra life.

Mistake 3: using methyl bromide pallets (MB stamp)

Methyl bromide-treated pallets are illegal to use for food growing in the UK. Check every pallet for the stamp. HT (heat-treated) is safe. KD (kiln dried) is safe. MB is not. Look on the side of the pallet for the IPPC mark.

Mistake 4: building the bed too wide

A 1.2m wide bed forces you to either walk on the soil (compacting it) or strain to reach the centre. Stay at 1m maximum. The reach from each side becomes 50cm, which everyone can manage comfortably.

Why we recommend ringing the scaffolder first

Why we recommend the scaffolder phone call: A 90-second phone call to a local scaffolder converts a £140 garden centre purchase into a £4 screw bill. We made 14 such calls across 11 years. Twelve resulted in free or sub-£5 board collections. The boards delivered are exactly the right thickness for raised beds, exactly long enough to cut into multiple sides, and exactly the kind of wood that lasts 6 to 8 years in UK weather. The phrase to use: “Hi, I am building raised beds for my allotment. Do you have any condemned or downgraded boards I could collect this week?” Twelve out of fourteen scaffolders said yes. Plan ahead, collect, store in a dry shed, build at leisure.

Frequently asked questions

Can you really build a raised bed for under £10?

Yes, using reclaimed scaffold boards or pallet wood plus £4 of screws and four corner stakes. The materials cost £8.40 to £9.80 if you source the wood through a local scaffolder, skip-find, or Freecycle. Building takes 35 to 50 minutes with a cordless drill.

Where do I get free wood for a raised bed UK?

Ring local scaffolding companies for condemned boards. Check local Freecycle, Facebook Marketplace ‘free’ listings, and Olio for builder leftovers. Construction skips are a good source if you ask the property owner first. Most scaffolders charge nothing for boards graded down from sale.

How long does a raised bed from scaffold boards last?

Six to eight years untreated in UK weather. Lift the boards 25mm off the soil on brick offcuts to extend life to 10+ years. Treated softwood from a garden centre lasts 10 to 15 years but costs ten times as much. Untreated reclaimed scaffold is the best value.

Is pressure-treated wood safe for vegetable growing?

Modern UK pressure-treatment uses copper-based preservatives (Tanalith E or similar) approved for kitchen garden use. Older CCA-treated wood from before 2006 contained arsenic and should not be used. Reclaimed scaffold boards are untreated and always safe for food growing.

What size raised bed is best for vegetables?

1m wide, 1.5 to 3m long, 200 to 300mm deep. The 1m width lets you reach the centre from either side without standing in the bed. Depths under 200mm restrict root vegetables. Depths over 300mm need 0.6 cubic metres of soil and cost more to fill.

Do I need to line a raised bed?

Only if grass or weeds underneath are a problem. Lay flattened cardboard or newspaper directly under the bed to suppress couch grass and bindweed before filling. Avoid plastic weed membrane, which restricts drainage and worm movement.

How much soil does a 1m x 2m raised bed need?

0.4 cubic metres at 200mm depth. Mix 50% topsoil, 30% well-rotted compost, 20% leaf mould or coir. A bulk delivery costs £35-£55 from local soil suppliers, or use your own compost mixed with bought topsoil at half the cost.

Now you have a £10 bed

A £10 raised bed beats a £140 garden centre bed on cost per year, on durability per pound, and on the satisfaction of building something useful from rejected materials. Make the scaffolder call this week.
