What is a CP12 Certificate?
A CP12 (also known as a Landlord Gas Safety Record or Gas Safety Certificate) is a legal document that confirms all gas appliances in a rental property have been checked and are safe to use.
We provide CP12 gas safety certificates for landlords and letting agents across Harrow, Stanmore, Watford, St Albans, Hemel Hempstead, Luton, Dunstable, Berkhamsted and surrounding areas. Annual gas safety inspections are a legal requirement for all rental properties. We issue certificates on completion and can schedule recurring annual visits across multiple properties so you never miss a deadline.
