Reasons for joining

Powerful Brand Affiliation

The TDCA logo is a recognised mark of professionalism, quality and best practice across the timber decking and cladding sector.

Displaying the TDCA member badge instantly strengthens your credibility, helping potential customers trust your business before the first conversation even starts. It signals that you are part of a respected trade body where standards matter, providing your clients with confidence to move forward and helping you stand out from unverified competitors.

Independent Third-Party Accreditation

DeckMark® and CladMark® are independent quality assurance schemes operated by TDCA and recognised across the industry by specifiers, designers and clients.

These accreditations provide vital third-party validation that products, suppliers and installers meet established performance and best-practice standards — reducing risk and increasing confidence at specification stage.

TDCA supports members on their journey towards accreditation, offering guidance and expertise to help raise quality and consistency. Many members find this process invaluable in improving internal standards, winning work and strengthening long-term reputation.

Expert Technical Support (When It Really Matters)

TDCA members gain access to a highly experienced technical team and independent auditors with deep commercial and industry knowledge.

Support is available by phone, email or in person, alongside free access to a growing library of downloadable technical guidance covering materials, design, installation and current building regulations. TDCA publications help define UK good practice and are referenced by organisations including the NHBC and Timber Development UK.

Where issues arise, TDCA can also assist in dispute resolution under the DeckMark® and CladMark® schemes - providing impartial expertise to help protect your business, reputation and client relationships.
