Your Guide to CERTASS Certification

Welcome to our simple guide to CERTASS certification, designed to help you make informed decision about choosing windows and doors for your home.

Understanding certifications like CERTASS is key to ensuring your home improvements are not only beautiful but also safe, compliant with building regulations, and add lasting value.

What is CERTASS?

CERTASS is a 'Competent Person Scheme' approved by the UK government.

For homeowners in Bristol and across the UK, this means installers accredited by CERTASS are assessed to ensure they meet standards of quality and competence. They are qualified to self-certify that their work complies with the relevant Building Regulations, saving you the hassle and extra cost of going through your local authority directly.

Why CERTASS Matters for Your Home

Enhanced Safety & Compliance

CERTASS installers are rigorously assessed and must adhere to strict building regulations. This ensures your new windows and / or doors are installed safely and correctly, meeting all legal requirements for energy efficiency, security, and structural integrity.

Protecting Your Investment

Choosing a CERTASS-registered installer provides peace of mind. It also adds tangible value to your property. Buyers recognise CERTASS as a mark of quality, making your home more attractive on the market and safeguarding your investment.

How to Check if an Installer is CERTASS Approved

When you’re investing in new windows or doors, it’s important to know that your installer is properly accredited. The good news is, checking CERTASS approval is simple and gives you instant peace of mind.

1. Ask for Their CERTASS Registration Details

A reputable company will always be happy to confirm their certification. You can ask for their CERTASS registration number or proof of membership before agreeing to any work.

2. Check the Official CERTASS Register

CERTASS provides an online search tool where you can verify if a company is registered. This allows you to confirm that your installer is approved to carry out work that meets Building Regulations, without relying on guesswork.

3. Look for Certification After Installation

Once your installation is complete, you should receive a CERTASS certificate. This document confirms that the work complies with Building Regulations and is an important record to keep safe, especially if you ever decide to sell your home.

If you don’t receive your certificate within a few weeks of installation, it’s always worth following up with your installer.
