Why Choose CQ-Assured
Workmanship Warranty Certification?

With CQ-Assured, installers can prove to homeowners that their workmanship meets appropriate industry standards, to give them more confidence to choose your business. CQ-Assured is available for a full range of trades, where a competent persons scheme isn’t required for certifying an installation.

Instead, installers can reassure homeowners with the knowledge that your work is inspected by an authorised certification scheme, as well as offering an insurance backed workmanship warranty from a leading insurance provider. Members can also be automatically registered with the TrustMark Government Endorsed Quality Scheme, proving that you are a contractor who has been vetted and meets the required standards, along with having a commitment to good customer service, good trading practices and technical competence. You’re a business that consumers can trust.

The CQ-Assured scheme is a workmanship standards scheme only and does not cover Building Regulations notification. Where Building Regulations notification is required, you will need to provide details either to an Approved Inspector or Local Authority Building Control. However, many of the scopes covered by the CQ-Assured scheme do not require Building Regulations notification. If you need advice on a project, feel free to contact our technical support team.

Joining the Certass CQ-Assured scheme is easy. All you need to do is fill in our simple application form. If you are an existing Certass member, you can add CQ-Assured certification scopes in your members area.
