Where to Buy Lumber & Sheet Materials in the UK: Top Suppliers, Tips & Smart Buying Advice

Why choosing the right lumber matters for your UK projects

Picking the right timber or sheet material can make or break a build. Whether you’re decking a garden, rehabbing a kitchen, or building a shed, lumber choices affect strength, durability, and how happy you’ll be with the finished job. Think of timber like the bones of a project — pick them wisely and the rest is easier.

Top UK timber suppliers you should know

There’s no single best supplier for everyone. Some retailers suit weekend DIYers, while others cater to builders and trade accounts. Below I highlight trusted chains and specialist suppliers across the UK so you can match the shop to your needs.

B&Q — convenience and DIY-friendly range

B&Q is a go-to for hobbyists who want a straightforward shopping trip. Expect sheets like plywood and MDF in common sizes, softwood boards in 6 ft and 8 ft lengths, and treated options for basic outdoor jobs. Prices are competitive and the range is easy to navigate if you’re planning smaller renovations.

Wickes — trade-ready stock with retail access

Wickes hits a sweet spot between DIY and trade. They stock structural timber, construction timber, and sheet goods such as 3/4" plywood and 1/2" MDF, plus pressure-treated boards for exterior use. Wickes often offers cutting services in-store, convenient if you need a few lengths trimmed to size.

Screwfix — fast, reliable, and good for smaller quantities

Screwfix is ideal when you want to grab specific timber or sheet materials quickly. It’s not the place to order truckloads, but it’s brilliant for screws, fixings, and small packs of timber in standard sizes. If you value speed and convenience, it’s worth a look.

Travis Perkins and Jewson — builders’ merchants for professionals

If you’re a tradesperson or tackling a large project, Travis Perkins and Jewson are the big names to consider. Both offer a wide choice of structural timber, treated joists, OSB, plywood in various thicknesses, and bespoke cutting on request. They also cater to bulk orders and can arrange palletised deliveries when you’re buying by the dozen.

Selco Builders Warehouse — trade-focused, wide selection

Selco is a favourite with professionals who need volume and variety. You’ll find timber in longer lengths, sheet sizes for different uses, and specialist items like CLS studwork and laminated beams. The trade accounts and bulk discounts make it attractive for larger jobs.

Howdens — kitchens and fitted joinery specialists

Howdens is a specialist in kitchens and fitted joinery. Their timber and sheet products are tuned to cabinetry and interior fit-outs. If you’re building units or need pre-finished carcasses and MDF kitchen-grade boards, Howdens offers trade-standard products with a professional finish.

Arnold Laver and Huws Gray — timber specialists

For a more timber-focused supplier, Arnold Laver and Huws Gray carry a deeper range of hardwoods, softwoods, decking-grade boards, and specialist sheet materials. They're great when you need higher-grade planks, bespoke cuts, or advice on species selection for furniture or visible joinery.

Different types of lumber and sheet materials — what’s best for your job?

It helps to know the key differences between common materials so you pick the right one first time. Here’s a run-down of what each product does best and when to use it.

Softwood boards (e.g., pine, spruce)

Softwoods are lightweight and inexpensive, making them perfect for structural framing, studwork, and general carpentry. Standard board lengths come in 6 ft and 8 ft, with thicknesses of 1" or 3/4" common depending on the use.

Hardwood boards (e.g., oak, ash)

Hardwoods are denser, more durable, and better for floors, stair treads, or visible furniture. Expect to pay more, but you get grain and longevity that softwood doesn’t match. Joiners often choose hardwood for cabinet doors and visible trim.

Plywood — strong, layered sheet material

Plywood is cross-laminated, which gives it strength across large panels. Typical thicknesses are 1/4", 1/2", and 3/4". Use it for subfloors, sheathing, and furniture where rigidity is key. Exterior-grade or marine plywood is available for damp conditions.

MDF — smooth finish for interiors

MDF is dense and smooth, so it’s perfect for painted joinery, skirting, and cabinet boxes. It doesn’t tolerate moisture well, so keep it indoors or opt for moisture-resistant MDF for high-humidity areas like bathrooms. Typical thicknesses include 1/4", 1/2", and 3/4".

OSB — structural, budget-friendly sheathing

OSB is cost-effective for roofing, subflooring, and wall sheathing. It’s engineered to take loads and often comes in sheets that cover a lot of area — useful when you want strength without the higher cost of plywood.

Decking boards and treated timber

For outdoor floors and gardens, choose pressure-treated softwood or composite decking. Treated boards resist rot and insect attack, and are usually sold in standard lengths like 8 ft. Composite decking lasts longer but costs more initially.

How to choose the right grade and treatment

Grades and treatments matter. Structural timber must meet strength grades; fence posts and decking need preservative treatment. Here’s a quick checklist so you don’t guess.

Strength and appearance grades

Strength grades tell you whether a board is suited to loadbearing use — look for graded softwood for joists and rafters. Appearance grades affect knots and visual defects, important for visible furniture or finish work.

Pressure treatment and preservative options

Pressure-treated timber is impregnated with preservatives to resist rot. For outdoor posts and decking choose treated wood; for indoor trim it’s usually unnecessary. If you plan to bury timber in the ground, always pick a treatment rated for ground contact.

Buying practicalities: sizing, cutting, and transport

Size and transport influence costs and effort. Buying smart can save you repeated trips and awkward handling on site.

Standard sizes and how to measure

Sheets commonly come as 4 ft by 8 ft. Boards often arrive in 6 ft or 8 ft lengths. When planning, measure twice and add a small waste allowance — usually 10% is a sensible buffer for cuts and mistakes. Remember to think about thickness: 3/4" plywood is standard for subfloors, while 1/2" is often fine for cabinet backs.

In-store cutting vs. home cutting

Many suppliers offer cutting services — an absolute lifesaver if you don’t own a table saw. Get a few cuts done at the store to avoid trying to haul giant sheets through narrow doors. If you cut at home, always clamp the work and use a guide to get clean edges.

Transport and handling tips

Timber is bulky — check whether your supplier offers drop-off delivery or pallet options for heavier orders. If you’re collecting, bring straps and a helper and protect the panels from sagging. For long lengths, support at intervals so boards don’t bend or warp in transport.

Where to find reclaimed and specialty timber

Want character or sustainability? Reclaimed timber delivers both. It’s great for furniture, mantels, and rustic finishes. Here’s where to look and what to expect.

Salvage yards and reclamation dealers

Reclamation yards and specialist dealers often carry old beams, floorboards, and architectural timber. They’re perfect if you want aged patina or eco-credentials. Expect to inspect each piece for rot and structural soundness; reclaimed timber can be a mixed bag, but the results are unique.

Online marketplaces and small merchants

Smaller timber merchants and online marketplaces sell specialty species and custom-cut boards. If you need a rare hardwood or a custom-width plank, a specialist supplier or online trade shop is often the best route.

Sustainability: certifications and responsible sourcing

Timber buying is increasingly about more than price. Certifications ensure forests are managed sustainably and that the wood is legally sourced.

FSC and PEFC explained

Look for FSC (Forest Stewardship Council) or PEFC (Programme for the Endorsement of Forest Certification) labels. These badges mean the wood comes from responsibly managed forests. If sustainability matters to you, insist on certified timber when ordering.

Reclaimed timber as a green option

Reclaimed wood sidesteps new harvests entirely. Using reclaimed materials reduces waste and gives your project a story. Just be mindful of hidden nails and prior treatments — always check before cutting or planing.

How to compare prices and avoid unexpected costs

Price-per-sheet or price-per-foot can hide differences in quality, treatment, and service. Here’s how to get a fair comparison so you don’t pay for what you don’t need.

Compare like-for-like — size, grade, and treatment

Always compare the same thickness, grade, and treated vs untreated options. A treated 1" board will cost more than an untreated 1" board, so make sure you’re not comparing apples and oranges. Also factor in cutting charges if you need pre-cut pieces.

Look for bulk discounts and trade accounts

If you’re buying a lot, ask about trade accounts and volume discounts. Builders’ merchants like Travis Perkins and Selco often offer better rates for palletised orders. For a one-off small job, a DIY chain could be more cost-effective despite higher per-item prices because there’s less minimum order hassle.

Handling, storage, and on-site care

How you store timber affects how it behaves. Warped or damp boards make life difficult; good storage saves time and money.

Storing flat and off the ground

Keep sheets flat, supported at 16" to 24" intervals, and off the ground on batten supports. Cover them to keep rain and dew off, but allow ventilation so condensation doesn’t build up. For long-term storage, keep lumber stacked and weighed to prevent bowing.

Acclimatisation before fitting

Let timber and sheet materials sit in their intended environment for a few days before final fitting. Wood expands and contracts with humidity; acclimatising reduces gaps and twisting after installation.

Final thoughts — plan, buy, build

Buying lumber is part strategy and part a feel for what works in your project. Match the supplier to the job: DIY chains for small runs, builders’ merchants for volume, and specialists for hardwoods or reclaimed pieces. Measure, compare, and don’t be shy about asking suppliers for advice — experience goes a long way in timber selection.

Whether you pick B&Q for convenience, Travis Perkins for trade support, or Arnold Laver for specialist hardwood, the right choices will save time and keep your build looking professional. Treat the process like choosing ingredients for a recipe: quality at the start makes the final dish taste better.

Conclusion

Finding the right lumber and sheet materials in the UK comes down to knowing what you need and matching it to the right supplier. From big-name DIY chains to specialist timber merchants, there’s a perfect option for every scale of project. Prioritise proper grading, suitable treatment, and correct storage to keep your build solid and long-lasting. With the right prep and supplier, you’ll be cutting, fixing, and finishing faster than you think.
