How to Get a Boiler Installation Certificate

To get a boiler installation certificate, visit the Gas Safe Register website and order a replacement online. You’ll need your property details and must pay a replacement fee. If you’ve had a new gas boiler installed, your installer should register the work. You’ll then receive a Building Regulations Compliance Certificate.

What Is a Boiler Installation Certificate?

A boiler installation certificate confirms your new or replacement gas boiler was registered under Building Regulations.

The official name is a Building Regulations Compliance Certificate. The document confirms you reported the installation to your local authority.

You may need the certificate when:

• Selling your home.
• Remortgaging your property.
• Checking when your boiler was installed.
• Providing proof of Building Regulations compliance.

The certificate is not proof that your boiler remains safe today. It records compliance at the time of installation.

Keep your certificate with your boiler manual, warranty and service records. Having the paperwork ready will save time if you ever need to produce it.

How to Get a Replacement Boiler Installation Certificate

Lost your certificate? You don’t need another boiler inspection if the original installation was registered.

You can order a replacement through Gas Safe Register without contacting your original installer.

Follow these steps:

1. Visit the Gas Safe Register replacement certificate page.
2. Enter your property address and the details requested.
3. Follow the instructions to locate your installation record.
4. Pay the replacement certificate fee.
5. Follow the delivery instructions.

Replacement certificates are only available for installations recorded through the relevant registration system.

If your installation cannot be found, don’t assume your boiler was never registered. The original notification may contain an incorrect address or other details.

Contact your installer to check the registration before taking further action.

How Do You Get a Certificate for a New Boiler?

When you have a new gas boiler installed in England or Wales, the Gas Safe registered business must notify the work.

The installer must report the installation within 30 days. Once the notification is processed, your Building Regulations Compliance Certificate is issued.

Certificates are usually sent within 10–15 working days after notification.

Your installer should also provide:

• A completed Benchmark commissioning checklist.
• Your boiler’s user instructions.
• Details of the manufacturer’s warranty.
• Information about future servicing.

The Benchmark checklist records the checks completed during your new boiler’s installation.

Your manufacturer’s warranty or guarantee may depend on registering the boiler with the manufacturer—often within a set period after installation—and having it serviced annually by a suitably qualified engineer. Service records should be kept in the Benchmark logbook.

Keep all your documents together. This will give you a record of the installation if questions arise later.

What If Your Boiler Was Never Registered?

You’ve contacted Gas Safe Register, but there’s no record of your boiler.

Now you need to establish whether the installation was reported.

Start with the engineer or company that fitted your boiler.

• Ask if the installation was registered.
• Request the notification date and reference number.
• Check whether your property address was recorded correctly.
• Ask the installer to resolve any missing notification.
• Contact Gas Safe Register if the installer refuses to help.

If the original installer has closed, another suitably qualified Gas Safe registered business may be able to inspect, commission and notify the installation.

This is not the same as ordering a replacement certificate. The engineer must follow the correct notification process.

If the problem remains unresolved, contact your local authority Building Control department.

A Gas Safety Certificate cannot replace missing Building Regulations approval.

Do You Need a Boiler Installation Certificate When Selling Your House?

You’re selling your home. Your solicitor asks for the boiler installation certificate.

You search through the paperwork, but find nothing.

Now your buyer’s solicitor wants answers. Was the boiler registered? Who installed it? Does the work meet Building Regulations?

Missing paperwork can trigger extra enquiries and delay your sale.

Before your property goes on the market:

• Find your boiler installation documents.
• Check whether you have the original compliance certificate.
• Order a replacement if you’re missing it.
• Ask your installer to investigate any missing registration.
• Speak to your solicitor if you cannot obtain the document.

Your solicitor may discuss indemnity insurance if the certificate cannot be found.

This insurance can protect a buyer and lender against certain losses arising from local authority enforcement action. Still, it does not confirm that the boiler was installed safely or make the installation compliant.

Don’t leave the paperwork until your buyer asks for it. Finding the certificate early can help avoid problems during the sale.
