What Is a Gas Safety Certificate CP12 in London?
A Gas Safety Certificate CP12 is a legal document that confirms all gas appliances, flues and pipework in a property have been inspected and meet current gas safety standards. In the UK, landlords are legally required to obtain a valid CP12 every 12 months for any property with gas appliances before renting it out.
During a CP12 gas safety check in London, a Gas Safe registered engineer visits your property and carries out tests on your boiler, cooker, hob and any other gas appliances. They check for leaks, correct operation, adequate ventilation, flue performance and carbon monoxide risks. Once the inspection is complete, you receive a digital CP12 with full test results, appliance details and the engineer’s credentials.

Why a Gas Safety Certificate CP12 Is Important
Gas appliances that are poorly installed, unmaintained or faulty can lead to gas leaks, fires and carbon monoxide poisoning. A Gas Safety Certificate CP12 ensures that your boiler, hob, cooker and gas fire are operating safely and in line with current UK regulations.
For landlords, a valid CP12 is not optional – it is a legal requirement every 12 months. Without it, you could face fines, prosecution or invalidated insurance in the event of an incident. Tenants are also becoming more aware of their rights and often request proof of gas safety before signing a tenancy agreement.
A current CP12 certificate demonstrates that you have met your gas safety duties as a landlord under UK law and protects you from penalties.
Regular inspections significantly reduce the risk of carbon monoxide leaks, explosions and dangerous faults in gas appliances.
Identifying issues early prevents costly breakdowns and damage to boilers, pipework and property, saving you money in the long term.
