Assure Certification
Windows and glazing · Competent person scheme for replacement glazing
Assure Certification operates a competent person scheme for specified window and door installation work. Its scheme allows approved installers to self-certify eligible work rather than using an individual building control application.
Checked Official sources below.
What it covers and whether it is required
Assure‘s competent person route is for England and Wales. Scheme membership is voluntary, but the relevant Building Regulations requirements and notification duties are not optional.
Joining requirements and costs
Apply for the relevant installation scope and provide the business and competence evidence requested by Assure. Confirm the current assessment, insurance, guarantee and ongoing monitoring requirements before joining. Do not assume a general glazing qualification automatically grants scheme registration.
Check the current fees with Assure Certification 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
Check the installer directly with Assure and confirm that the job is eligible for scheme notification. Obtain the compliance certificate and separate warranty documents. For work outside scope, agree who will arrange the alternative building control process.
How to check a claim
Official member, card or certificate check: Assure Certification.
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
England and Wales for the competent person self-certification route. Confirm separate arrangements before relying on registration for a project elsewhere.
Common questions
Can Assure registration be used instead of every planning or building approval?
No. It covers only eligible work within the scheme. Planning permission and other approvals must be considered separately where required.
How do I check Assure Certification status?
Use the official verification service linked in this guide. Match the person or legal business name, current status and relevant work category. For a guarantee, check the document issued for your contract as well.
