How to get a replacement boiler certificate
A boiler installation certificate is issued when a new or replacement boiler is installed. This important document will be needed if you plan on selling your house in the future. If you've lost yours, don't worry, we share how to get a replacement certificate.
What is a boiler installation certificate?
A boiler installation certificate is a document issued to prove a new boiler was installed by a Gas Safe registered engineer. This document is also known as a Building Regulations Compliance Certificate.
Current building regulations in the UK state that local authorities must be informed whenever a gas boiler is installed into a property. As well as homeowners receiving this important documentation, a copy of the certificate will also be sent to the local authority.
A boiler installation certificate is only issued once. It does not need to be renewed annually, but a new certificate will be needed following a boiler replacement.
Difference between Gas Safety and boiler certificate
Boiler installation certificates and Gas Safety certificates are two different documents.
Gas Safe certificates - also known as CP12 documents - are legally required for all UK landlords. This document is issued annually and is only provided once all of a rental property's gas appliances have been checked by a registered engineer.
A Gas Safe certificate proves that all of the property's gas appliances are non-hazardous and leak free.
In comparison, boiler installation certificates are only issued once. This document confirms that the boiler was installed by a registered professional and is required for all properties, not just rentals.
It is recommended for all boilers to be serviced annually by a registered engineer. Unlike landlords, homeowners do not legally need to acquire a Gas Safety certificate following a service.
A boiler installation certificate is only issued following a new or replacement boiler installation, not after an annual service.

It is not uncommon for household documents to get lost from time to time. If you can't find your boiler certificate, don't panic.
Follow these steps to get a replacement boiler installation certificate:
Request a replacement from the Gas Safe Register - It is possible to order a replacement boiler certificate online. All you need to do is visit the Gas Safe Register website and request a replacement
Provide your details - You will need to provide the Gas Safe Register with your home address and contact email information
Pay a fee - You will need to pay a small fee for a replacement boiler certificate. This will need to be paid when you submit your request via the Gas Safe Register website
Receive certificate - A replacement boiler certificate will be sent to your email, providing your installation details, which can be found on the Gas Safe Register system. If no boiler is matched to your address, you will need to contact your installing engineer to make sure the Gas Safe Register were notified of the installation

Is it illegal to sell a house without a boiler installation certificate?
If you are selling your property, you will need a boiler installation certificate. Unlike gas safety certificates, the boiler installation document is legally required for all homeowners.
Issues can arise when trying to sell a house without a boiler installation certificate. This documentation confirms that a registered engineer installed your boiler and complies with building regulations.
It is unlikely that your buyers will be happy to go ahead with the purchase without this legal certification.
Selling up and can't find your boiler installation certificate? Don't worry, you have options:
1. Request a replacement from Corgi or the Gas Safe Register
You can replace your boiler installation certificate by contacting the Gas Safe Register. Simply follow the steps we shared earlier.
Alternatively, contact Corgi for a replacement if your boiler was installed before 2009.
2. Get a retrospective boiler installation certificate
Engineers can occasionally fail to notify the Gas Safe Register of a new boiler installation.
If you are unable to get a replacement certificate, it may be because your boiler was never registered. In this situation, you will need to hire a Gas Safe registered engineer to issue a retrospective boiler installation certificate.
A registered engineer will inspect your boiler and issue a retrospective certificate, providing the installation meets the necessary safety standards.
The gas engineer may need to make repairs or alterations to your boiler to make sure it is compliant with current building regulations.
3. Provide boiler indemnity insurance and an up to date Gas Safety certificate
Your final option is to offer your buyers boiler indemnity insurance for added peace of mind. This insurance will protect your buyer of any financial losses should the Local Authority decide to remove the 'unregistered' or 'non-compliant' boiler.
If indemnity insurance doesn't provide your buyers with enough reassurance, you can also provide them with an up to date Gas Safety certificate. This document will prove that your boiler and other gas appliances meet the necessary safety standards.
Replacement gas safe certificate costs
Replacing a boiler installation certificate comes with a small fee. A new certificate from the Gas Safe Register costs £7.92 (including VAT), while replacement boiler certificates from Corgi are more expensive, at £40 + VAT.
Prices have been taken from the Gas Safe Register and Corgi websites and may be subject to change (information accurate at time of writing, September 2024).
