Consumer Protection

We work with our Scheme Providers and Registered Businesses to improve consumer protection and standards across all sectors

Quality Assurance

Tradesperson shaking hands

All Registered Businesses are vetted and monitored by our Scheme Providers to ensure they meet high standards of technical competence, customer service and trading practices. Our Scheme Providers carry out these checks so you don’t have to.

TrustMark undertakes ongoing monitoring of Scheme Providers and for works lodged in our Data Warehouse we carry out both desktop monitoring and risk-based inspections on works carried out by Registered Businesses to give even greater assurance that you’re making the right choice.

Dispute Resolution Process

Quality assurance and effective consumer protection is at the heart of everything TrustMark aims to deliver.


However, we recognise that occasionally things don’t go as planned and it is important that if this happens consumers can access a clear, user-friendly process. This process ensures that complaints are resolved efficiently and fairly, which is why we’ve made this a requirement for Registered Businesses and Scheme Providers. Most problems can be resolved quickly and easily by contacting the business directly, but if that does not resolve the problem, further help is on hand.


To give consumers an additional layer of protection and to reinforce our commitment to quality and consumer protection, we are members of the Dispute Resolution Ombudsman (DRO).

In the unlikely event that the complaints process of the Registered Business and Scheme Provider is exhausted and the dispute remains unresolved, consumers have the option to raise a dispute with the DRO who independently investigates the complaint to help reach and fair and reasonable outcome.

Our ‘If Things Go Wrong’ page gives more information on what to do in the event of a problem.

Trading Standards Approved

TrustMark offers a national ‘Trading Standards Approved’ option of a membership for its Registered Businesses as an additional level of customer confidence delivered through its primary authority partner, Buckinghamshire & Surrey Trading Standards.

TrustMark actively works with Buckinghamshire and Surrey Trading Standards to ensure that our vetting criteria for businesses through our Scheme Providers and the operation of the TrustMark Quality scheme meets and exceeds their minimum standards.

Our Escrow Service for Homeowners & Registered Businesses

Registered Businesses trading records and financial positions are checked by Scheme Providers when they are first registered under the TrustMark Scheme. They are also subject to monitoring and audit to ensure they continue to meet TrustMark’s high standards. However, such checks cannot guarantee that a business will never encounter financial difficulties whilst works are being undertaken.

Escrow is a legal arrangement in which a third party temporarily holds sums of money until a particular condition has been met, for example, completion of an agreed percentage of the works. TrustMark has partnered with Transpact (Europe’s leading escrow service) to provide this optional service for homeowners and businesses as an added level of protection.

It is a very low-cost, straightforward process. A contract is negotiated between the Registered Business and their customer, covering the works to be carried out, associated costings and what would trigger payments back to the consumer. These details and a schedule of payments and dates are agreed by both parties. Once the escrow proposal has been agreed upon and the monies transferred, both parties are .

The customer knows their money is completely safe, right up to the point that they are totally satisfied with the completed work, at which point it is released to the tradesperson. You can be sure you will only pay what was agreed, at the appropriate time and only when you are happy with the work that has been carried out.
