Being a landlord in UK, you need to be responsible for the gas safety of your tenants. So if your rented property has got gas appliances like a boiler, cooker, water heater, radiators, etc, it requires a Gas Safety Certificate. Now, this gas safety certificate can only be issued by a Gas Safe Registered engineer.

If you are found using any gas appliances in your rented property without a gas safety check, then it's a great offense. Moreover, to ensure that your gas appliances are all functioning absolutely fine without any flaws, these Landlord Gas Safety Checks should be carried out every year by a gas safe registered engineer. While doing the Safety Check, if the engineers inspect any minor or major defects in the gas appliances, they get that fixed, ensuring the complete safety of their tenants.
