Boiler Servicing in Sussex
An annual service keeps your boiler safe, efficient, and your manufacturer warranty valid. Carried out by Gas Safe registered engineers (No. 966527) at a time that suits you.
Why Your Boiler Needs an Annual Service
A boiler is the hardest-working appliance in your home, and like any piece of machinery it performs best with regular care. An annual service keeps it running safely and efficiently - and crucially, almost every manufacturer warranty requires one. Miss a yearly service and a 10 or 12-year warranty can become void overnight.
Our Gas Safe registered engineers service all major boiler brands across Sussex, including Worcester Bosch, Vaillant, Ideal, Alpha, and Glow-worm. Each service follows the manufacturer's own checklist, and we update your service record so your warranty stays watertight.
A well-serviced boiler also runs more efficiently, which means lower gas bills - and small issues get caught before they become winter breakdowns.
What's Included in Every Service
Flue Gas Analysis
We test the combustion gases to confirm your boiler is burning safely and efficiently.
Visual & Component Inspection
Burner, heat exchanger, seals, and ignition checked against the manufacturer's schedule.
Pressure & Expansion Vessel Check
System pressure verified and the expansion vessel recharged if needed.
Controls & Safety Device Test
Thermostats, timers, and safety cut-outs tested to make sure everything responds as it should.
Condensate & Flue Check
Condensate trap and pipework inspected, flue checked for secure fittings and correct operation.
Service Record Updated
Your benchmark service record completed and logged - the proof your warranty provider needs.
When Is the Best Time to Book?
Most people only think about their boiler when it stops working - usually in the coldest week of the year. The smartest time to book a service is late spring or summer, when engineers have more availability and any parts that need ordering won't leave you without heating.
If your boiler was installed by us, we'll remind you when your annual service is due so your warranty never lapses.
Servicing for Landlords
If you let a property, an annual boiler service pairs naturally with your legal gas safety inspection. We can carry out both in a single visit and issue your CP12 certificate on the same day - one appointment, one invoice, full compliance. See our gas safety certificate service for details.

Boiler Servicing FAQs
How long does a boiler service take?
A full service typically takes 45 minutes to an hour. If we find anything that needs attention, we'll explain it clearly and quote before doing any additional work.
Will skipping a service really void my warranty?
In most cases, yes. Nearly all manufacturers - including Worcester Bosch, Vaillant, and Ideal - require an annual service by a Gas Safe registered engineer as a condition of their warranty. The service record is your proof.
Do you service all boiler brands?
Yes. Our engineers service all major brands, whether or not we installed the boiler. We follow each manufacturer's own service schedule.
What happens if you find a fault during the service?
We'll show you the issue, explain what it means in plain English, and give you a clear price for the repair. There's never any pressure - the decision is always yours.
How much does a boiler service cost in Sussex?
We keep our servicing competitively priced and confirm the cost clearly when you book, so there are no surprises. If you combine it with a landlord gas safety certificate, we offer a reduced combined rate - just ask when booking.
