An annual boiler service costs between £90 and £200 and keeps your boiler safe, efficient and within its manufacturer warranty. During a service a Gas Safe engineer replaces the burner seals and gaskets, flushes the burners, cleans the traps, recharges the expansion vessels and runs safety checks. Regular servicing lowers running costs and catches small faults before they become expensive breakdowns.
A boiler service is one of those jobs that is easy to skip when everything seems fine, right up until the morning it is not. Servicing your boiler once a year is a small, predictable cost that keeps your heating safe, holds your warranty in place and catches little faults long before they turn into expensive breakdowns. Here at H.M.D Plumbing & Heating we service boilers across Canvey Island and south Essex, so here is exactly what happens during a service and why it is worth booking in.
What a Service Includes
A proper boiler service is thorough. It is far more than a quick look and a tick in a box. When Harry services your boiler, the work includes:
- Replacing burner seals and gaskets: These wear over time and are key to the boiler burning cleanly and safely. Fresh seals keep everything sealed as it should be.
- Flushing through the burners: Clearing out the burners keeps combustion clean and efficient, which helps the boiler run smoothly and use less gas.
- Cleaning out the traps: The condensate traps get cleaned so waste water drains away properly and does not cause blockages or faults.
- Recharging the expansion vessels: The expansion vessel keeps system pressure steady. Recharging it protects the boiler and avoids pressure problems down the line.
- Full safety checks: The gas safety checks confirm the boiler is burning correctly and operating safely, with no risk to your home.
If anything needs attention beyond the service, Harry explains it clearly and honestly before doing any further work, so there are never any surprises.
Why Do It Every Year
A yearly service is not just a formality. It pays for itself in several ways.
- Safety: A serviced boiler burns cleanly and safely. Regular checks catch issues like poor combustion early, protecting your household from carbon monoxide risk.
- Efficiency: A clean, well-tuned boiler uses less gas to heat your home, which shows up as lower running costs over the year.
- Warranty: Most manufacturers require an annual service to keep the warranty valid. Skip it and you could lose cover on an expensive part.
- Catch faults early: Small problems spotted during a service are cheap to fix. Left alone, they are the faults that turn into a breakdown on the coldest night of the year.
Put simply, a service is the difference between a boiler that is looked after and one that is left to fend for itself until it fails.

Book a ServiceWhat a Service Costs
An annual boiler service costs between £90 and £200 depending on the make and model of your boiler. We confirm the exact price when you book, with no hidden extras.
- Standard service: Most common combi and system boilers sit at the lower end of that range.
- More involved boilers: Some makes and models take longer to strip down and service properly, which is reflected in the price.
- Landlord certificates: If you are a landlord and need a Gas Safety Certificate for a rental, let us know when you book and we can arrange that alongside the service.
Set against the cost of a mid-winter breakdown, or losing your manufacturer warranty, a yearly service is one of the cheaper ways to look after your home.
The Best Time to Book
You can service a boiler at any time of year, but autumn is the popular choice, and for good reason. Booking in before the cold weather arrives means your boiler is checked and ready just as you start relying on it every day. It also means any small fault is put right before the heating is under real load.
Autumn does get busy, so booking a little ahead avoids the rush. That said, if your boiler is overdue a service now, do not wait for a particular season. Whenever the last service was more than a year ago, it is worth getting booked in.
