Why Use an STA Member?

As the largest UK trade association within the structural timber sector, there are a host of reasons why construction professionals and self builders should choose one of our members. The STA's mission is to enhance quality and drive product innovation through technical guidance and research, underpinned by a members' quality standard assessment – the STA Assure Membership and Quality Standards Scheme.

STA Assure
is designed to benefit both clients and members by promoting the differing accreditations and quality standards held by individual STA member companies. This scheme offers reassurances to the construction community that our members meet or even exceed current legislation and regulatory requirements.

We have established three levels of membership accreditation - Gold, Silver and Bronze. Offering complete transparency to new and existing clients, the accreditation highlights the differing levels of quality procedures, management systems and product performance standards, together with external accreditations held by STA members.

It is important to note that it is not always feasible, possible or necessary for a member to achieve a Gold level membership. Specific quality requirements differ for each type of member and customer activity depending on the nature of a company's business; therefore, a Bronze or Silver member may be the most appropriate company for your project requirement. 

The STA has reached a formal agreement with the NHBC, from January 2019 the NHBC will accept STA Assure Gold members as compliant with Chapter 6.2 of NHBC's assessment processes for timber structures without the need for further review or completing a HB2445 form.

STA Assure has also received formal recognition from six other the industry leading structural warranty and building control bodies including; LABC Warranty, Premier Guarantee, Protek Warranty, Build-Zone Warranty, Self-Build Zone Warranty and ABC+ Warranty for STA Assure Gold and Silver members.
