Upgrade to a high-efficiency combi or system boiler. Gas Safe registered, fully insured, and backed by up to 10-year warranties.
A new boiler is one of the most significant investments you will make in your home's comfort and energy efficiency. At A Clarke Plumbing & Heating LTD, I specialize in professional, clean, and reliable gas boiler replacements tailored to your property. I am fully Gas Safe registered and help you choose the best system configuration for your household.
Whether your boiler has suffered a major breakdown, is costing too much in repairs, or you want to lower your carbon footprint and save on monthly energy bills, I provide expert guidance, neat copper pipework, and clean handovers.
Heats water instantly direct from the mains. Highly compact, removing the need for storage tanks. Best for apartments and 1-2 bathroom homes.
Requires a hot water cylinder to store heated water but no loft tanks. Ideal for homes with multiple bathrooms and high simultaneous hot water demands.
Works alongside a separate cylinder and header tanks in the loft. Typically chosen to directly replace traditional layouts without changing pipe dynamics.
Boiler heat output is measured in kilowatts (kW). Sizing your boiler correctly ensures high efficiency and adequate heating.
Best suited for apartments, flats, and smaller terrace homes. Ideal for setups with 1 bathroom and up to 10 radiators.
Best suited for 3-4 bedroom semi-detached and detached family homes. Designed for configurations with 1-2 bathrooms and up to 15 radiators.
Best suited for large detached properties. Perfect for properties with multiple bathrooms, high simultaneous hot water demand, and 15+ radiators.
Boiler replacements depend heavily on cold water mains flow rates, the number of active radiators, and hot water cylinder setups. Speak with me, your local Gas Safe registered engineer, to arrange a free, comprehensive on-site survey.
I perform a chemical flush of existing radiators to clear black sludge before connecting your new boiler.
Installed on return pipes to trap ongoing metallic debris, protecting the boiler heat exchanger.

I register your parts and labor warranty directly with the manufacturer to ensure it is immediately active.
I do not believe in cutting corners. To comply with Building Regulations and ensure manufacturer warranties remain fully valid, every replacement boiler I install includes essential protective accessories.

I provide clean, structured installations with minimal disruption to your household.
