We are gas safe and carry out boiler replacements, new installations and conversions. We also carry out servicing and landlord safety certificates.
A malfunctioning boiler is more than just an inconvenience. It can compromise your household's safety and lead to costly emergency bills. At A Clarke Plumbing & Heating LTD, I provide comprehensive annual boiler servicing and rapid emergency diagnostic repairs. I am fully Gas Safe registered and specialise in resolving boiler faults for homeowners and landlords in Basingstoke and Hampshire.
My focus is on preventative maintenance: keeping your heating system running at maximum fuel efficiency, ensuring your family is safe from carbon monoxide hazards, and addressing minor parts wear before it leads to a complete system shutdown.
If your boiler is leaking, losing pressure constantly, showing an error code, or has completely failed, call our direct line.
A boiler is a complex gas appliance that experiences high temperatures and pressures daily. Neglecting annual servicing can lead to reduced fuel efficiency (increasing gas bills), sudden winter breakdowns, and potential carbon monoxide safety risks.
Additionally, nearly all leading boiler brands (Worcester Bosch, Vaillant, Ideal) require an annual service record stamped by a Gas Safe engineer to keep your parts and labor warranty active. Failing to schedule a check can void your entire coverage.
Most brands require an annual service record to keep your parts and labor warranty fully valid.
Checking casing seals and flue integrity ensures no combustion gas leaks into your living spaces.
Burner optimisation and gas pressure calibration improve energy efficiency, reducing gas waste.
Replacing weak seals or gaskets during a routine check prevents severe water damage later.
I carry out professional repairs on all major combi, system, and conventional boiler designs.
Replacing faulty expansion vessels, leaky automatic air vents (AAVs), or broken pressure relief valves to stop leaks and restore pressure.
Swapping out failed central heating circulation pumps, stuck diverter valves (which switch water between radiators and hot water taps), or gas valves.
Diagnosing boiler ignition lockouts, sensor faults (NTC thermistors), fan blower breakdowns, and electronic controller board (PCB) failures.
Addressing cold spots in radiators caused by trapped air or sludge, replacing faulty TRV valves, and clearing blockages with localised flushing.
