Why Book a Boiler Service?

Reduce your energy usage & bills
A well-tuned boiler burns less gas to heat your home.

Be assured your boiler is safe to use
Safety devices, flue and combustion checked by a Gas Safe engineer.

Avoid breakdowns & costly repairs
We spot small problems early, before they leave you without heat.

Keep your boiler guarantee valid
Most manufacturers require an annual service to honour the warranty.
Boiler servicing in Southampton: what to know
Southampton has hard water, which leaves limescale in boilers over time — especially the plate heat exchanger in combi boilers. An annual service picks up the early signs before they turn into a breakdown.
We cover SO14–SO19, SO30, SO31, SO40, including Shirley, Woolston, Bitterne, Portswood, Millbrook, Sholing and the surrounding area.
What's included in every service
Combustion analysis
Flue gas readings taken with a calibrated analyser to confirm safe, efficient burning.
Burner & seals
Burner, heat exchanger, seals and gaskets inspected and cleaned where needed.
Safety devices
Flame supervision, pressure relief and other safety devices tested.
Pressure & expansion
System pressure checked and adjusted, expansion vessel inspected.
Controls
Programmer, thermostat and smart controls checked for correct operation.
Written record
A written record of what we checked, readings taken and any recommendations.

All major brands serviced
Combi, system or regular boiler — if it runs on gas, we can service it.
Landlords: gas safety certificates (CP12)
UK landlords must have every gas appliance checked by a Gas Safe registered engineer every 12 months. We carry out Landlord Gas Safety Records for single properties and portfolios, and work with letting agents across Southampton.
When should I book?
Late summer or early autumn is ideal — before you rely on your heating for winter, giving time to order any parts. We service boilers all year round, so book whenever suits you.
