Book before the cold
Late summer or early autumn, before the first cold week fills every engineer’s diary.
Heating · Servicing
An annual service that actually looks inside.
A proper service means taking the case off. We check the burner, heat exchanger, seals and condensate trap, test the safety devices and analyse the flue gases, then give you a written record and a plain account of anything we found.
- Gas Safe registered
- MCS heat pumps
- F-Gas certified
What’s included
The work, done properly.
- Flue gas analysis and combustion check
- Burner, heat exchanger and electrodes inspected and cleaned where needed
- Condensate trap and pipe cleared and checked
- Gas pressure, seals and flue integrity tested
- System pressure and expansion vessel checked
- Controls, safety devices and pressure relief valve tested
- Service record completed for your warranty
Signs you need this
- It has been more than a year since the last service
- Your boiler warranty depends on an annual service
- Gas bills creeping up for the same warmth
- Sooty marks or staining around the boiler or flue (stop using it and call us)
- You are a landlord and the gas safety check is due too
Most of the breakdowns we see in January were visible in September: a condensate trap half full of sludge, a worn electrode, a seal starting to perish, an expansion vessel that has lost its charge. A service is the cheapest point to catch them.
Manufacturer warranties usually require a service every year by a Gas Safe registered engineer, recorded in the Benchmark checklist at the back of the manual. Miss one and a warranty claim can be refused, so we complete the record every time.
A service is not the same as a landlord’s gas safety check. The safety check confirms an appliance is safe to use; the service keeps it working well. Landlords often have both done on the same visit.

Questions
Boiler servicing, answered.
How long does a boiler service take?
Usually around an hour for a domestic boiler, longer if it needs a deeper clean or a part replaced.
My boiler works fine. Does it still need a service?
Ideally, yes. The faults behind winter breakdowns build up slowly, and many warranties need the annual record. Servicing a working boiler is the point.
Is a service the same as a gas safety certificate?
No. A gas safety check is what landlords need each year to show an appliance is safe. A service goes further and cleans and adjusts the boiler. We can do both at once.
