“FENSA’s mission is to improve window and door replacements across the UK, by professionalising installers and protecting homeowners.” It’s a governing body that is for homeowners and is there to protect them against any type of fraud or mishap that happens on a job. Therefore FENSA carries out continual checks for building improvement companies and double glazing installers to make sure they meet the standards set out by FENSA’s requirements.

How does this affect you?

It’s always good to make sure the double glazing installer you’re considering is FENSA certified. It gives homeowners the peace of mind that they’re a fully qualified company that have essentially been given the thumbs up to carry out work for homeowners and fall within FENSA standards and requirements. If a company is not FENSA certified, you may want to look elsewhere for a double glazing quote and work.
