Annual Boiler Servicing
An annual boiler service is not an optional extra — it is part of responsible home ownership. It protects your warranty, may be required by your home insurance, and ensures your boiler is operating safely and efficiently.
What Our Service Includes
- Visual inspection of the boiler, flue, and pipework connections
- Checking gas pressure and combustion quality
- Cleaning of burner, heat exchanger, and accessible components
- Testing safety devices (pressure relief valve, thermostat, controls)
- Checking the flue for safe and correct operation
- Testing the system for leaks
- Issuing a signed service record upon satisfactory completion
Why Annual Servicing Matters
Most manufacturer warranties — including Worcester Bosch, Vaillant, Ideal, and Baxi — require annual servicing to remain valid. Skip a service and you may lose cover when you need it most.
Many home insurance policies require gas appliances to be maintained in good working order. An unserviced boiler can invalidate a claim. We provide a service record on completion.
A boiler service includes a safety check covering the heat exchanger (for cracks that could allow combustion gases inside) and the flue. These are safety-critical checks only Gas Safe engineers can perform.
Scale and debris accumulation reduces boiler efficiency over time. A serviced boiler burns less gas to produce the same heat output — reducing your bills.

What Our Customers Say
50+ five-star reviews from homeowners and landlords across Kent.
"Absolutely professional from start to finish. The engineer arrived on time, explained everything clearly, and left no mess behind. Our new Worcester Bosch is running perfectly. Would recommend without hesitation."
"Called about a boiler fault on a Wednesday and they were with me by Thursday. Diagnosed the problem in under an hour, fixed it the same day, and gave me a fixed price before touching anything. Exactly what you want."
"Booked a Gas Safety Certificate for my rental property — same week appointment, certificate emailed before the engineer left the driveway. Efficient and professional. Will use again next year."
"Used them for CP12 inspections across three properties now. Always on time, always professional, certificates issued same day. Exactly what a busy landlord needs."
"Had the whole central heating system replaced after moving into an older house. Brilliant job — finished on time, no mess, and the Nest thermostat they installed is brilliant. Very pleased."
"Power flush made a huge difference — radiators that were barely warm are now fully heating. Should have done it years ago. Fair price and good communication throughout."
Frequently Asked Questions
How much does a boiler service cost?
A standard annual boiler service in the Tonbridge area typically costs £80–£120. This covers a safety check, efficiency assessment, and cleaning of key components. We issue a service record upon completion.
How much does a boiler repair cost?
Repair costs vary depending on the fault. Minor repairs such as replacing a pressure relief valve typically cost £100–£200 including parts. More significant repairs — heat exchanger, pump, PCB — can cost £250–£600. We diagnose the fault first and provide a fixed-price quote before any repair work begins.
Is it cheaper to repair or replace a boiler?
A useful rule of thumb is the "50% rule": if repair costs exceed 50% of the cost of a new boiler, replacement is likely the better investment. We give honest advice — we have no incentive to recommend a repair when replacement makes more financial sense.
What are the warning signs that my boiler needs attention?
Warning signs include: unusual banging or whistling noises; pressure gauge below 1 bar or above 3 bar; pilot light going out repeatedly; boiler cycling on and off frequently; radiators not heating evenly; increased gas bills; and visible corrosion or water around the boiler casing.
Will my home insurance be affected if I do not service my boiler?
Many home insurance policies require gas appliances to be maintained in good working order. Failure to service your boiler annually can invalidate a claim. We issue a signed service record after each service, which can be provided to your insurer if required.
