British Board of Agrément
Standards and certification · Product assessment and certification body
The British Board of Agrément assesses construction products, systems and related processes. Its Agrément certificates describe the scope, performance and conditions of use of the named product or system.

What it covers and whether it is required
BBA certification is not a statutory licence for a tradesperson. A product certificate can provide technical evidence, but the design and installation must still meet current rules and the certificate’s conditions.
Joining requirements and costs
Manufacturers and other applicants choose the relevant product, process or installer service and provide the evidence needed for assessment. Testing, manufacturing controls and ongoing requirements depend on the certification service. Do not assume a product certificate is an installer qualification.
Check the current fees with British Board of Agrément before applying. Ask whether the quotation includes application, assessment, renewal and any per-job charges. Use published fees or ask for a written quotation.
What it means for homeowners
Find the exact certificate through BBA’s search service and read the intended use, limitations and installation requirements. BBA warns that regulatory references in certificates may need checking against current rules. Product performance evidence does not remove the designer’s or installer’s responsibilities.
How to check a claim
Official member, card or certificate check: British Board of Agrément.
Match the record to the named person or contracting business. Check the current scope, not just a logo on a van or an old certificate. If the public record does not show the detail you need, ask the body to confirm it before appointing the business.
Where the scheme applies
UK construction assessment with products also used elsewhere. Check the certificate’s stated regulatory context and suitability for the particular nation and application.
Common questions
Does a BBA certificate approve any installer using the product?
No. Product certification and installer approval are different services. Check the certificate conditions and any installer scheme separately.
How do I check British Board of Agrément status?
Use the official service linked in this guide, or ask the organisation to confirm the exact status or document. Membership, a training award, a product certificate and a project guarantee are different things.
