The Federation of Master Builders


TrustMark is the only Government endorsed standards scheme for trades that operate in and around the home.

As a Member, TrustMark is a badge you can be proud of and, displayed alongside the FMB logo, offers a high level of reassurance to clients that you are amongst the best builders in the country.

What is TrustMark?

TrustMark is a not-for-profit social enterprise, developed in 2005 with Government, industry and consumer protection bodies. Its aim is to give consumers confidence in firms to undertake work that is of high quality, is protected and delivered at agreed costs.

The Scheme’s Operators and Registered Firms commit to meeting a set of Core Criteria, which are reviewed and updated annually.

Why join TrustMark?

The FMB is dedicated to ensuring our Members are able to provide consumers with a high quality service and the peace of mind that they are hiring an independently vetted and inspected builder.

By becoming a TrustMark member you can prove to clients that your business delivers Trustmark’s 3 Cornerstones of Quality:

TrustMark membership provides an additional shop window for FMB Members, with the TrustMark website getting over 750,000 consumer visits per month. You will also receive logos for your van, website and business materials that, together with the FMB logo, offer additional reassurance for clients.

Joining TrustMark

Builders and other trades can only join TrustMark through a registered Scheme Operator relevant to their trade. It is not possible to join TrustMark directly. The FMB is the largest of all the Scheme Operators and the only one that is specifically for builders, meaning we can provide a wide range of unique benefits and services to builders.

It’s the Member’s choice whether to take TrustMark registration in addition to their existing FMB membership.

TrustMark membership costs £78 (including VAT) in addition to the annual FMB Membership.

You can also access an even higher level of reassurance for clients through TrustMark’s National Trading Standards Approval Scheme. This entails additional checks and costs an additional £150 +VAT per annum.
