A FENSA certificate is an important document that confirms your windows or doors were installed by a registered FENSA installer and comply with building regulations in England and Wales. It’s especially useful when selling a home, getting insurance, or proving energy efficiency compliance.
If you’ve lost it or never received one, here’s how to get a replacement or check if one exists.
✅ What Is a FENSA Certificate?
- Issued when windows, doors, or roof lights are replaced in residential properties
- Confirms the work meets building regulations
- Shows the installer was FENSA registered
- Typically issued within a few weeks after installation
📄 How to Obtain a FENSA Certificate
1. Order a Replacement Certificate Online
If your installation was registered with FENSA:
🔗 Go to the official site:
www.fensa.org.uk/consumer/your-certificate
You’ll need:
- House number/name
- Postcode
The system will search for matching FENSA-registered installations at your address.
Cost:
- £25 for a replacement certificate (as of current FENSA rates)
2. Check With Your Installer
If you know the company that did the installation:
- Contact them and ask for your FENSA registration number
- They may be able to resend the certificate or confirm the work was registered
✅ Only FENSA-approved installers can issue these certificates.
3. Contact FENSA Support
If you’re having trouble online, contact FENSA directly:
📧 Email: enquiries@fensa.org.uk
📞 Phone: 020 7645 3700
🕒 Mon–Fri, 9am–5pm
Provide your address, date of installation, and installer name (if known).
🏠 What If There Is No FENSA Certificate?
If the work wasn’t carried out by a FENSA-registered company, or if it was DIY:
- You may need to apply for retrospective building approval through your local council
- This is called a Regularisation Certificate
This can be more costly and time-consuming than using a registered installer.
🧠 When Do You Need a FENSA Certificate?
- Selling your home
- Remortgaging or home valuation
- Proving compliance with building regulations
- Home insurance checks
