FENSA Certificate: What Is It, How To Get Yours or Replace a Lost Certificate

29 February 2024

Let’s demystify what a FENSA certificate is all about. It’s essentially your proof that the new windows and doors in your house comply with the latest UK building regulations, particularly around energy efficiency and security.

If you own a home and have been looking at replacing windows and doors, you’ve likely heard of FENSA certificates and FENSA-approved installers.

Understanding FENSA

FENSA – short for Fenestration Self-Assessment Scheme – was set up by the government to streamline the process of certifying window and door installations.

Before this, every new installation needed a thumbs up from the local building control, which could be quite a drawn-out affair.

Now, if you use a FENSA-approved installer, they can self-certify the work, making life a lot easier.

Why You Need a FENSA Certificate

Having a FENSA certificate is pretty important for a number of reasons:

  1. Compliance: It’s your evidence that your windows and doors meet legal standards.
  2. Selling your home: It’s likely to come up when you sell your home, as buyers will want to see proof that any work done is up to code.
  3. Energy efficiency: It confirms your installations are designed to keep the heat in, potentially lowering your energy bills.
  4. Insurance: Sometimes, insurers ask to see compliance certificates like these.

This can make a FENSA certificate an invaluable piece of paperwork to keep safe, especially if you don’t want to have to order a replacement later on.

How to Get One

When you get new windows or doors fitted, choose a FENSA-approved installer. They handle the installation and then register the work with FENSA.

Once that’s done, you’ll get your certificate either by email or through the post.

It’s pretty straightforward – the key is using an approved installer from the start.

Lost Your Certificate?

If you’ve lost your certificate and need a new one, it’s not a huge problem.

You can order a replacement FENSA certificate directly from the FENSA website for a small fee. You’ll need some details about your property and the installation, and then they’ll send out a new one.

A FENSA certificate is more than just a piece of paper; it’s your reassurance that your window and door installations are up to standard, saving you energy and keeping your property safe and sound. Whether you’re updating your property, preparing to sell, or just keeping your paperwork in order, it’s an important document to have in your possession.
