Don’t put up with fines, problems with getting things done, or anything dangerous happening. KCS Electrics offers dependable Gas Safety inspections throughout London, done by engineers officially registered with the Gas Safe Register.

It’s official proof that gas appliances, connections, and flues are safe for use, and it’s given to you after a qualified engineer has checked them.
During the inspection, the engineer tests things like boilers, cookers, and gas fires to make sure they work safely and properly. They also check the ventilation, the flue flow, and the overall installation.
Afterward, you’ll get a Gas Safety Certificate (for landlords) saying if everything’s okay or if anything needs fixing. This certificate is vital for demonstrating you’re following the rules and protecting your tenants.

Yes. Under the Gas Safety (Installation and Use) Regulations 1998, landlords in the UK are legally required to have a current landlord gas safety certificate.
Every rental property with gas appliances needs a yearly gas safety inspection, performed by someone on the Gas Safe Register. This certificate needs renewing every twelve months, and a copy must be given to your tenants within 28 days of the inspection, with a minimum of two years’ record-keeping.
Ignoring these rules could lead to serious trouble: fines, legal proceedings, and your insurance being declared invalid.

This includes:
We use professional equipment to find faults you wouldn’t usually spot during a normal check. Each inspection is conducted by a Gas Safe-registered engineer, guaranteeing that everything is done by the book.
You’ll then get your Gas Safety Certificate (CP12), which confirms whether the property is safe or if repairs are needed.
The price of a Gas Safety Certificate depends on how many appliances you have and how complex their installations are. Larger properties, or having more appliances, will take longer to inspect and influence the price.
We give you a clear price tailored to your property, so you only pay for what you need.
Once the inspection is finished, we issue the certificate promptly. Most CP12 certificates are emailed to you within 24 to 48 hours – helping you stay compliant without waiting around.
