Certass (Certification & Self Assessment) is a Competent Persons Scheme, licensed by the Department for Communities and Local Government. Certass Glazing is a scheme in respect of the installation of replacement windows, doors and associated glazing products in domestic properties. Approval by Certass Glazing will allow member contractors to Self-Certify work, therefore Certass Glazing will be in a position to issue Building Regulation Completion Certificates to homeowners.
The Certass Glazing Membership year runs from the date of initial approval therefore each contractor’s annual period will be unique.
