New windows need to comply with building regulations.

You should bear in mind that, unless you are just replacing the glass or something small, a new or complete replacement window should meet with current building regulations (with regard to energy efficiency) in your area.

If you use a FENSA or CERTASS registered installer, they can certify the window as compliant and save you the trouble & cost of doing it yourself.

This becomes more important the more windows & doors you are seeking to replace.

Always get at least 4 or 5 written quotes for the full cost of installing your new double glazed windows & doors from different fully accredited installers who can ‘self-certify’ for building regulations compliance.
