Gas Services
Landlord Gas Safety Certificates (CP12) in Kent & London
Annual landlord gas safety checks and CP12 certificates for rented property across Kent and London.
If you let a property with gas in it, the annual gas safety check is your responsibility and not your tenant’s. Every gas appliance, flue and length of pipework you provide has to be checked once a year by a Gas Safe registered engineer, and your tenant has to be given a copy of the record.
Plumbusters has been doing them for landlords and letting agents across Kent and London for over 30 years. We check boilers, warm air heaters, cookers and gas fires, and we also work on oil and LPG. The record is emailed to you the same day.

What the check covers
Every gas appliance you provide gets checked, including the cooker, the gas fire and any warm air heater, along with the pipework and flues that serve them:
- A gas tightness test on the installation, with the meter and emergency control valve checked
- Every gas appliance you provide checked in turn: boiler, warm air heater, cooker, hob, gas fire and gas water heater
- Flues and chimneys tested, to confirm the products of combustion go where they should
- Ventilation checked. Blocked or boxed-in air vents are one of the commonest faults we find
- Burner pressure and gas rate against the manufacturer’s figures, where the appliance allows it
- Safety devices tested, including flame supervision on older fires and cookers
- Anything unsafe made safe on the spot, with the reason set out in writing
- The record emailed to you the same day, ready to pass to your tenant
- The annual boiler or warm air service done at the same visit if you want it
We price by where the property is and how many appliances are in it, so ring 01622 474008 or request a call back and you’ll have a figure before anything is booked. If you have more than one property, ask about a service plan and we’ll keep track of the renewal dates for you.

Our Testimonials
Reviews from homeowners, landlords and businesses we’ve worked for.
I have used Plumbusters for years for servicing my boiler and some great small jobs. This time it was a new boiler moved up two flights of stairs. All work was neat and tidy, with some fantastic pipe work, like a work of art. Considering the effort to take up carpet and floorboards, there are no corners cut and the best job done, not the quickest job just to move on to the next customer. Even the outside plastering of the old outlet pipe was made to look like bricks! At the end there was a full walk through to make sure everything was working and 2 follow up checks. Great job.

Having only just moved into a new home, we were reliant upon recommendation by the previous owners. Plumbusters have been remarkably responsive and did an amazing job that turned out to be far more than first anticipated. We now have a swanky streamline vertical radiator in our family room along with two extra radiators on two upstairs bedrooms. Faultlessly clean, Grant gets our vote today. Thanks to you all. Now have you down as our preferred company for all things plumbing related. Best wishes. Mike & Joanne

We found the engineer sent from Plumbusters to be very helpful and knowledgeable and clean and tidy in his work. They were quick to respond and reliable and professional while in our house. We would be happy to recommend them to anyone who is looking for a plumber.
