Oil & Off-Grid
Oil Boiler Servicing
Annual oil boiler servicing by OFTEC registered engineers, with a combustion analysis and a written record.

An oil boiler that hasn’t been serviced doesn’t usually stop working. It just quietly gets worse — a sooty nozzle here, a partly blocked filter there — until one cold morning it locks out and you’re without heat and hot water. Nearly every winter lockout we attend was avoidable at the last service.
We are OFTEC registered for commissioning, servicing and repair, and we’ve been looking after heating in Kent for over 30 years. Oil-heated homes across Kent, Essex, East Sussex, Surrey and Berkshire — same family firm, same engineers, one phone call.
What an oil boiler service includes
A service is a proper strip and set-up, not a look and a tick. Pulling the baffles and cleaning the heat exchanger properly takes a couple of hours, not the twenty minutes a quick once-over takes — and you get the readings in writing at the end so you can see what was actually done.
- Combustion analysis with a calibrated analyser, and the burner set to the manufacturer’s figures — not left where it was found
- New fuel filter every time, and a new nozzle whenever it needs one — between them they cause most lockouts
- Baffles and heat exchanger cleaned down, so you’re not paying to heat a layer of soot
- Photocell, electrodes and pump pressure checked and adjusted
- Tank, bund, fuel line and fire valve inspected — splits, corrosion, weeping joints and a fire valve that still works
- Controls, thermostat and timer checked so the system runs when you actually want it to
- A written record of the readings, and a straight answer on anything that needs attention
We price servicing over the phone rather than publishing one figure for everyone, because it depends where you are and what the boiler is. Ring 01622 474008 or request a call back and you’ll have a price before anything is booked in.

What our clients think
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.
