FENSA is a government authorised Competent Persons Scheme for the replacement of windows and doors in England and Wales. You should always use a FENSA registered double glazing company. We cannot stress enough the importance of ensuring that your new windows and doors are fitted by an ethical company who take a pride and responsibility in their work. By choosing a FENSA registered installer you are ensuring that the work is completed to a high standard and meets all the relevant building regulations.

Why choose a FENSA member?

FENSA stands for the Fenestration Self-Assessment Scheme; the scheme was set up on request of the Government so that companies are able to certify an installation while following the correct building regulations. This means that the project can still be completed to the highest standard but it will be much quicker because you don't have to go through the long procedures of your towns planning department.

FENSA members are vetted thoroughly before they are able to join and members are continually inspected to make sure they are following the correct procedures. Using a FENSA member for your window and door installation is much easier and faster and it's likely to save you quite a bit of money as you won't have to register the work with your local authority.

When will I receive my FENSA certificate?

We issue a FENSA certificate for every installation, it's important to keep your certificate safe as it shows that the correct building regulations have been followed. You will often need proof of a FENSA certificate before selling your home if the windows were installed after 2002.

We're committed to delivering the highest quality products to our customers which is why we have our own team of quality controllers to make sure you're completely satisfied, because of this it can take around 6-8 weeks for you to receive the FENSA certificate . We would advise to wait until 10 weeks after signing your satisfaction to the work completed before contacting us or FENSA. If you have not received the certificate in this time or you need it desperately then you can contact FENSA on 0207 6453 700 to look into it for you.
