What a gas boiler service in Sunderland actually checks
A proper service is more than a visual glance. We work through the boiler and the installation so there is a record of how it is operating on the day.
- flue gas readings with an analyser
- burner, electrodes and heat exchanger inspected and cleaned where required
- combustion chamber seals checked
- gas pressure and flow checked against manufacturer information
- condensate trap and pipe checked
- flue route and terminal inspected
- safety devices and heating controls tested
If your hot water has become slow to warm up, the boiler is noisy or pressure keeps falling, mention it when you book. We can then look for the underlying cause rather than treating the visit as a box-ticking exercise.
Why every year
Annual servicing helps identify developing faults and is commonly required by boiler manufacturers to maintain warranty cover. Keep the written record with your boiler paperwork in case you need it later.
Book a check sooner if you spot any of these
These symptoms can point to a developing fault rather than routine servicing alone.
Pressure falling
If you are topping up the pressure every few weeks, water may be escaping somewhere or an internal component may need attention.

Boiler noise can point to poor circulation, scale or sludge and is worth checking rather than ignoring.
Read moreUnexpected lockouts
If the boiler regularly needs resetting, the service visit should include finding the reason rather than simply clearing the code.
Error code helpCold patches on radiators
Radiators cold at the bottom often point to sludge in the heating system rather than a boiler fault.
Read moreWhere we service boilers in Sunderland
We work across Sunderland from our base in Houghton le Spring, including the city centre and areas such as Hendon, Ashbrooke, Ryhope, Silksworth, Doxford Park, Farringdon, Grindon, Pallion, Millfield, Southwick, Castletown, Hylton Castle, Redhouse, Roker, Fulwell and Seaburn.
Older terraces can have longer flue runs and older system pipework, while newer properties often have boilers that are still under manufacturer warranty. Near the coast, external flue terminals and fittings are worth checking carefully because of exposure.
If the boiler is already broken down, this is not the routine service page you need: go directly to a repair or out of hours cover for no heating or hot water.
