An annual boiler service costs £100 to £150 and keeps your boiler safe, efficient and within its manufacturer warranty. During a service a Gas Safe engineer checks the safety-critical parts, cleans the burner, tests the boiler and gives it a full check over. Regular servicing lowers running costs and catches small faults before they become expensive.
A boiler service is one of those jobs that is easy to put off, especially when the boiler seems to be working fine. But an annual service is one of the best-value things you can do for your heating. It keeps your boiler safe, keeps it running efficiently, and keeps your warranty valid, all for £100 to £150. In this guide we explain what a service actually involves and why it is worth booking every year, for homes across Portsmouth and the wider Hampshire area.
What an Annual Service Is
An annual boiler service is a thorough check of your boiler by a Gas Safe registered engineer, carried out once a year. The idea is simple: catch any small issues before they turn into breakdowns, make sure the boiler is safe, and keep it running as efficiently as it did when it was new.
It is not the same as a repair. A service is planned, routine maintenance. Most services take under an hour, and you come away knowing your boiler has been properly checked over and is in good order for the year ahead. For most homes, £100 to £150 covers it.
What a Service Includes
A proper service is more than a quick glance at the boiler. Here is what our Gas Safe engineers check during a PHG service.
- Safety checks: we inspect the safety-critical components to make sure the boiler is operating safely, with no risk of a gas leak or carbon monoxide.
- Burner and internal clean: we clean the burner and other key parts so the boiler burns cleanly and efficiently.
- Gas pressure and flue: we test the gas pressure and check the flue is clear and venting correctly.
- Controls and performance: we test that the boiler fires up and runs correctly, and that the controls are working as they should.
- Full check over: we look over the wider system and flag anything that needs attention, explaining it clearly before doing any further work.
If we find something that needs putting right, we tell you straight and talk through the options. There is never any pressure, just honest advice.

Book a ServiceKeeping Your Warranty Valid
This is the one that catches a lot of homeowners out. Most boiler manufacturers only keep your warranty valid if the boiler is serviced every year by a Gas Safe registered engineer, and the service is logged. Miss a service and you risk voiding the warranty, which can leave you paying for repairs that would otherwise have been covered.
On a boiler with a long warranty, that annual service is what keeps years of cover in place. Weighed against the cost of a major repair or a new part out of your own pocket, a service is a small price to protect a lot of value. We log every service so your records are always in order.
Safety and Savings
Beyond the warranty, an annual service earns its keep in two ways that matter to every household.
- Safety: a faulty boiler can produce carbon monoxide, which is colourless and odourless. A service checks the boiler is burning cleanly and venting safely, which protects your household. We always recommend a working carbon monoxide alarm alongside regular servicing.
- Efficiency and savings: a clean, well-tuned boiler uses less gas to heat your home. Over a year that keeps your energy bills down, so the service can pay for part of itself in lower running costs.
- Fewer breakdowns: catching a worn part early is far cheaper and less stressful than an emergency call out on a cold morning, especially in the middle of winter.
A serviced boiler is a safer, cheaper and more reliable boiler, which is why we recommend it to every customer.
When to Book
The best time to book a service is before you really need the heating, which for most homes means late summer or autumn. That way any issues are sorted before the cold sets in, and you are not waiting for a repair during the busiest part of the year.
- Autumn is popular: a service before winter means your boiler is ready when you start using it every day.
- Keep it yearly: aim for roughly the same time each year so you never let a service lapse and never risk your warranty.
- Any time works: we service boilers all year round, so if yours is overdue, there is no need to wait.
We can set up a yearly reminder so your service never slips, keeping your boiler safe, efficient and within warranty year after year.
