Oil & Off-Grid
Oil Heating
OFTEC registered oil boiler servicing, repairs and replacements for off-grid homes.
If your home is off the gas grid you already know the problem: most heating firms only do gas, and the ones that will look at an oil boiler are often a single van booked up until spring. Plumbusters is OFTEC registered for oil-fired appliance installation and for commissioning, servicing and repair — so the same family firm that has looked after Kent’s boilers for over 30 years can look after your oil system too.
We cover oil-heated homes across Kent and into Essex, East Sussex, Surrey and Berkshire — from the Weald villages around Sevenoaks, Tunbridge Wells and Ashford to the rural stretches of Braintree, Uttlesford and Maldon. Servicing, breakdowns, new boilers, tank and fuel line checks: one engineer, one phone call.
Oil heating services offered
Oil boilers are simple, reliable machines when they’re set up properly — and expensive to run when they aren’t. A burner that’s out of adjustment quietly wastes kerosene, which matters more than ever after the price swings of the last year. Most of what we do starts with getting those basics right.
- Annual oil boiler service with a combustion analysis and proper burner set-up — not just a quick look
- Breakdowns and lockouts — fault finding and repairs to burners, pumps, photocells and controls
- Pre-winter “lockout-proof” check: new nozzle and filter, tank and fuel line inspection, so the boiler doesn’t fail on the first cold morning
- Like-for-like oil boiler replacements — internal, external and kitchen models from Grant, Worcester Bosch and other leading makes
- Oil tank and fuel line condition checks, including the things your oil supplier and insurer look for
- Honest advice on HVO renewable fuel and heat pumps, without pushing you towards either
- Landlord servicing and safety checks for oil-heated rental properties
We quote oil work over the phone rather than publishing set prices, because every property is different and we’d rather give you an accurate figure than a headline one. Ring 01622 474008 or request a call back and we’ll price the job properly before anyone comes out.

Our Testimonials
We love our clients and they love our work. Our team is very experienced in both residential and commercial projects.
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.
