Quick answer
A Potterton boiler service is an annual safety and performance check carried out by a Gas Safe registered engineer. It covers a visual inspection, checks on gas pressure and flue integrity, combustion analysis with a flue gas analyser, inspection and cleaning of key components where required, and checks on safety devices and the condensate system. Potterton is part of the same group as Baxi, so many parts and controls are shared. Annual servicing is usually a condition of the manufacturer’s warranty.
Key takeaways
- Potterton is a long-established UK brand within the Baxi group, with combi, system and regular boilers.
- A service includes combustion analysis, flue checks, safety device checks and condensate inspection.
- Annual servicing by a Gas Safe engineer is typically required to keep the warranty valid.
- Many Potterton faults mirror Baxi faults because of shared components.
- Older Potterton boilers, including some non-condensing models, can still be serviced safely.
Potterton boilers you are likely to have
Potterton has made boilers in the UK for decades. Current and recent models include combi and system boilers in the Assure and Titanium ranges, alongside older Promax, Performa and Gold models still running in many homes. Some older Potterton regular boilers with permanent pilot lights also remain in service in older properties.
What a Potterton service includes
- Visual inspection of the boiler, flue, pipework and surrounding area for signs of leaks, corrosion or heat damage.
- Gas checks, including working gas pressure and gas rate.
- Flue checks to confirm the flue is intact, correctly sealed and terminating safely. See what flue gas analysis is.
- Combustion analysis with a calibrated analyser to check carbon monoxide and carbon dioxide levels.
- Burner, electrodes and heat exchanger inspection and cleaning where the manufacturer’s instructions require it.
- Condensate trap and pipe inspection and clearing. See condensate pipe checks.
- Safety devices, including pressure relief valve and overheat protection.
- Expansion vessel charge check on sealed systems.
- Benchmark record completed. See benchmark service record explained.
Common Potterton fault patterns
Because Potterton shares much of its engineering with Baxi, you may see similar issues: ignition lockouts linked to gas supply or condensate (see Baxi E133), pressure loss from expansion vessels, and diverter valve wear on combis (see diverter valve problems). Older models may suffer from worn pumps and PCB failures.
Warranty and servicing
Potterton warranties generally require the boiler to have been registered after installation and serviced every year by a Gas Safe engineer, with the service recorded. A missed service can mean a warranty claim is declined. Our article on boiler warranties and annual servicing explains why.
Older Potterton boilers
An older Potterton that is still passing its service can keep running safely, but parts for discontinued models become harder to find. If yours is a non-condensing model or has needed repeated repairs, it is worth reading boiler service for older boilers.
