Is it possible to get a gas safe certificate for an already installed boiler?

There are many reasons why you might want to get hold of a gas safe certificate after your boiler has already been installed.

Perhaps you’re planning on renting out a property, in which case you’re legally required to provide tenants with a gas safe certificate confirming all gas appliances are safe and functional.

Or, maybe you’re looking to sell and want to assure prospective buyers that your gas installations and appliances are safe and up to standard.

Whatever the reason, getting a safety certificate retrospectively is certainly doable. Below, we answer the question in a bit more detail.

Can I get a gas safe certificate for an already installed boiler?

In short, yes. 

Ideally, you should try to track down the original installer, as some gas safe engineers don’t like to sign off on another’s work.

If you can’t find the original gas engineer, don’t worry. Most will be happy to issue a certificate, but they will likely want to carry out a full inspection first.

This may involve removing and refitting the boiler and flue, visually inspecting or refitting the gas pipe, checking the pressure release discharge, and anything else they need to do to ensure compliance with building regulations.

The best thing to do is book a gas safety inspection as soon as possible, both for your own peace of mind and to obtain a certificate.
