TrustMark is a not-for-profit social enterprise and the only Government Endorsed Quality Scheme in the UK covering home improvements in or around the home.


The whole ethos of TrustMark is our passion for quality - it underpins what TrustMark stands for - continual improvement, best practice, excellent customer service and protection.

TrustMark operates within a Master Licence Agreement issued by the Government’s Department for Business, Energy and Industrial Strategy (BEIS).

TrustMark is overseen by an independent Board, working with an independent Financial Protection Panel; both of whom were appointed in 2018. We are further supported by our close working relationship with the National Consumer Federation.

What We Do - For Homeowners

We provide a high level of assurance, certainty and protection to homeowners looking to have work done in and around their homes. TrustMark Registered Businesses are thoroughly vetted and continually monitored to ensure they meet required standards in technical competence, customer service and trading practices, so homeowners can be sure they’re making the right choice.

And, if anything should go wrong, TrustMark has that covered too as registered businesses must provide guarantees on their work and have a clear and simple disputes resolution process in place.

What We Do - For Tradespeople

We work closely with our Scheme Providers and Registered Businesses to advance and improve these work standards and help promote these accredited tradespeople to homeowners. By becoming TrustMark registered, businesses can demonstrate their ongoing commitment to customer service, high standards and continual improvement.

How We Work


TrustMark is a not-for-profit social enterprise established in 2005 in conjunction with Government, industry bodies and consumer protection groups.

We continually re-invest in the scheme, working with Scheme Providers and Registered Businesses to improve consumer protection and standards across all sectors.

The Each Home Counts review, published in 2016, identified that greater consistency and quality in standards of workmanship, technical ability and customer protection was needed across the industry.

New regulations (ECO3: improving consumer protection), which were developed based on the recommendations from the Each Home Counts review, include TrustMark.

This means that all tradespeople carrying out energy improvements must be TrustMark registered and adhere to the TrustMark Framework Operating Requirement (FOR), providing greater levels of assurance and protection to homeowners.

The responsibility for the administration of the Energy Company Obligations (ECO) technical monitoring moved from Ofgem to TrustMark on 1st July 2021.

TrustMark licences and audits over 35 Scheme Providers with over 15,000 Registered Businesses. These encompass 156 different service types and include everything you might expect: plumbers, electricians and builders to a few you might not: carpet cleaners, landscape gardeners and leadwork specialists, plus most trades in-between.
