Gas Safety Certificates

There are many different types of gas safety certificate that can be issued. Many of them are done when a gas appliance is installed. When most people enquire about a “gas safety certificate” it relates to annual safety checks.

Having a gas safety certificate issued annually for gas appliances is a legal requirement for landlords of residential rented properties. This certificate is referred to as a Gas Safety Record (CP12). Annual safety checks must be carried out by a qualified Gas Safe registered engineer.

An annual Gas Safety Record (CP12) ensures gas appliances at a property comply with UK gas safety regulations. We believe customers should be provided with a more detailed assessment of their boiler beyond standard safety checks to highlight any possible problems.

Annual servicing

Boiler manufacturers each have their own warranty conditions. An annual Gas Safety Record (CP12) is not always enough to satisfy these conditions. Instead they stipulate how the boiler must be serviced.

We can service your boiler in accordance with manufacturer guidelines. We offer a combined Gas Safety Record (CP12) and service visit package.

Symptoms of carbon monoxide poisoning

Although it’s not a legal requirement, if you’re a homeowner, you should have an annual gas safety certificate done. Gas appliances that aren’t checked regularly can leave you and your family at risk of carbon monoxide poisoning.

We strongly recommend for everyone to be aware of the symptoms of carbon monoxide poisoning.
