Campaign Launched to Champion British-Grown C16 Timber

INDEPENDENT builders’ merchant MKM Building Supplies has joined forces with supplier James Jones & Sons to launch a UK-wide campaign championing the use of British-grown C16 timber.

Each year MKM supplies more than 150,000 tonnes of timber to tradespeople, developers, and the general public across the UK – that’s the equivalent weight of more than 12,000 double-decker buses.

The “Great British Timber” push puts the spotlight on C16’s strength, value, and sustainability -busting myths and giving branch teams and customers the know-how to make informed choices.

Combining in-branch education, staff training, digital content and promotional activity across MKM’s 135-strong branch network, a roadshow will also tour 20 key MKM locations this autumn, giving customers the chance to learn more about C16 and take part in interactive activities.

James Jones will be hosting drop-in training sessions for branch teams, offering the chance to sharpen skills and stay up to date with the latest information. Covering areas like conversion and span tables, storage best practice, and customer guidance, the sessions are all about strengthening the knowledge teams already have and ensuring confidence when talking about C16.

Gareth Nicholls, Head of Timber Category for MKM, said: “At MKM, we’re all about doing what’s right—for our customers and for the trade. This focus is about cutting through the noise and giving people clear, practical info on C16, so they can pick the right timber for the job.

“We’re determined to do our bit to back British-grown timber — not just by talking about it, but by giving our branch teams the tools to have those conversations with customers. James Jones is a partner we’ve worked with for almost 30 years — we’re proud to shine a light on the benefits of British timber.”

Championing C16 Timber

Traditionally, assumptions have been that imported C24 timber is always the stronger or more suitable choice. For most projects — from loft extensions and floor joists to walls, decking, fencing and garden structures — C16 performs just as well.

Emma Loftus, James Jones & Sons, added: “Too often, C24 is specified by default — but C16 is suitable for most everyday projects. By choosing C16, tradespeople and homeowners can support British forestry, protect jobs, and cut down on timber miles. Our fully sustainable approach also means customers know they’re choosing the best option that makes the most of every tree.

“This is a brilliant campaign with MKM — a merchant determined to do their bit for British timber. We can’t wait to get out on the road, have conversations that keep branches informed or even change perceptions about C16. Ensuring MKM remains the most knowledgeable partner for its customers.”

The British forestry industry contributes £3bn to the economy and supports more than 34,000 jobs. All C16 timber supplied by James Jones is grown in the UK, with a manufacturing process that ensures every single part of the tree is used — whether for construction timber, engineered timber products, OSB, or even animal bedding.

The campaign also ties into wider industry efforts to promote British-grown timber, with James Jones working alongside other UK suppliers and trade bodies. Together the industry are raising awareness among architects and specifiers and highlighting the benefits of choosing British timber.
