FENSA Approved Installers

FENSA is a government-authorised scheme that monitors building regulation compliance for home improvement products, including windows and doors. Each FENSA Approved Installer is assessed regularly to ensure it remains compliant with Building Regulations.

As FENSA registered installers, we can self-certify compliance with Building Regulations to prove window, door and rooflight replacements have undergone strict quality procedures. This is to protect the health and safety of those living near and inside the property. When we have completed your home improvement project, you will be issued a FENSA certificate. This certificate is essential when selling your home.

GGFi Membership

GGFi membership allows us to provide comprehensive insurance-backed guarantees on all of our products. In the highly unlikely event that we ceased to trade, your installation would be still covered for any legitimate faults for the duration of the guarantee period. GGFi membership also offers deposit protection insurance, if required.

Thanks to this partnership, you can enjoy complete peace of mind, knowing that any issue that arises with your project can be resolved.
