Having spent plenty of time, money and resource on the style, design & configuration of your doors & windows, sadly, the less glamorous part of the overall process, the installation, can often be overlooked. The first crucial decision is who to employ to fit your new items. There are a number of different options including your retailer’s own installers, a family friend or one further option definitely worth exploring, is using a FENSA approved Individual Professional Installer.


FENSA is a government-authorised scheme that monitors building regulation compliance for replacement windows and doors. Every FENSA Approved Installer, from large national brands to small local companies, is assessed regularly by us to ensure its standards are continually maintained.

FENSA’s mission is to improve window and door replacements across the UK, by professionalising installers and protecting homeowners. They make sure the work complies with building regulations, is energy efficient, and registered with the local council. And verify that every FENSA Approved Installer’s guarantee is insured.

Since 2002, FENSA has been authorised by the government to issue the renowned FENSA certificate: proof that your window and door installations are compliant, energy efficient, and registered. This proof is vital when selling your home. When you use a FENSA Approved Installer, rather than having to arrange an inspection from your Local Building Control Officer, the team at FENSA notify them for you – and you get a certificate to prove it.
