An annual Gas Safety Certificate (CP12) confirms that every gas appliance in your home has been checked by a Gas Safe registered engineer and is safe to use. Whether you need one as a landlord, before selling a property, or simply for peace of mind, we carry out the full check and issue your certificate the same day.

Gas Safety Certificates Expert
Landlords in St Albans are legally required to have a valid Gas Safety Certificate for every rental property, renewed every 12 months. Homeowners often ask for one too, whether that’s for a house sale, a mortgage requirement, or simply to know their boiler, hob and gas fire are safe. We check every gas appliance and flue in the property, test for leaks and correct ventilation, and issue your CP12 certificate on the day, provided everything passes.

Gas Safety Certificates Guide
Faulty gas appliances can leak carbon monoxide, a gas you cannot see or smell, which makes regular checks essential rather than optional. An annual safety check catches worn seals, blocked flues and poor ventilation before they become dangerous. For landlords, it’s also a legal duty under the Gas Safety (Installation and Use) Regulations, with certificates that must be given to tenants and renewed every year without exception.

COMMON WARNING SIGNS
A few reasons homeowners and landlords book a check sooner rather than later.
Every gas appliance, flue and pipe connection in the property is inspected and tested.
You'll receive a signed CP12 certificate the same day, provided all appliances pass.
Required by law for rental properties in St Albans, renewed every 12 months.

ThanksPosted on Google Deepak M.BTrustindex verifies that the original source of the review is Google. I recently had my boiler serviced by Heatgap( 99 Byron Road,Luton) and I couldn’t be happier with the experience. The Technician arrived on time, was professional, and explained everything clearly. The service was thorough, and they made sure the boiler was running safely and efficiently before leaving. What really stood out was their friendly attitude and attention to detail. They took the time to answer my questions and gave helpful advice on maintaining the boiler. Overall, excellent service from start to finish. I would definitely recommend Heatgap to anyone looking for reliable and professional boiler servicing.
