Boiler Service & Repairs, Gas Safety Check Services in Darlington, Stapleton, Mowden and beyond.


It’s a legal requirement for landlords to have all gas appliances, pipework, chimneys and flues checked every 12 months to make sure the property they’re renting out is safe for theitenants. Once this check has been completed, you will get your CP12. You’ll need to provide a copy to your tenants within 28 days and you’ll need to give one to new renters when they move in. Make sure you keep hold of old certificates as CP12s need to be kept for at least two years.

It’s really important that the check is only carried out by a Gas Safe registered engineer, or you won’t receive the proper legal certification.
If your tenants have brought any gas appliances with them, you are only responsible for the pipework that supplies them, but it’s worth including them in your annual check.


Gas Appliance Service is Crucial for: SAFETY Boiler service safety is of utmost importance when it comes to any gas appliance in your home, like doing a boiler check. The only way to ensure your boiler or appliance is functioning efficiently and safely is through proper maintenance and professional servicing every year with a boiler service. WARRANTY An annual boiler service is a requirement in order to maintain your gas appliance’s warranty. From £65
