How is timber priced in the UK?

Softwood from timber merchants is usually priced per linear metre at a given cross-section size (e.g. £3.50/m for 47×100mm C16). Hardwood is often priced per board foot or per cubic metre. Sheet goods are priced per sheet. Prices vary significantly between merchants.

Is VAT charged on timber?

Yes, timber in the UK is subject to 20% VAT. Trade merchants usually display prices ex-VAT while retail shops often include VAT. This calculator lets you toggle VAT on or off depending on how your merchant quotes.

What does C16 and C24 mean for timber?

C16 and C24 are strength grades for structural softwood under BS EN 338. C24 is stronger and more expensive. For non-structural woodworking projects, the grading matters less than the wood quality (straightness, knots, moisture content).

How can I get the best timber prices?

Buy in bulk for discounts, compare at least 3 timber merchants, consider rough-sawn over planed if you have a thicknesser, and look for pack deals on common sizes. Online timber merchants can sometimes offer better prices than local yards.
