Checking accreditations and building regulations

Replacement windows and external doors are covered by Building Regulations in England, and most installers self-certify their work through a competent person scheme rather than using council building control. Look for membership of FENSA or CERTASS, which allows the installer to issue a certificate confirming the work meets thermal and safety standards, a document you will need when selling the property. Many firms also register with the Glass and Glazing Federation (GGF) or hold TrustMark accreditation, and it is worth confirming that any deposit protection or insurance-backed guarantee is in place before work starts.

Comparing quotes and materials

Energy efficiency is shown by the window energy rating, a scale similar to appliance labels where A is the most efficient, and by the glass U-value, where a lower figure means better heat retention. When comparing quotes, check whether the price covers making good the plaster and reveals, the disposal of old frames and the type of profile and glazing used, as uPVC, aluminium and timber differ in cost and lifespan. A written quotation, a clear guarantee period and evidence of past work in Milton Keynes will help you compare installers on a like for like basis.

Do I need building control approval for new windows or doors?

Replacement windows and external doors must meet Building Regulations, but you usually do not need to contact building control if you use an installer registered with a competent person scheme such as FENSA or CERTASS. They will self-certify the work and issue a compliance certificate. If your installer is not registered, you will need to arrange building control yourself.

What guarantees should I expect from a windows and doors installer?

Most reputable installers offer a workmanship and product guarantee, often ten years, and many provide an insurance-backed guarantee so the cover continues if the company ceases trading. Ask for the guarantee terms in writing, check what is included, and keep your FENSA or CERTASS certificate with your property documents.
