Boiler packed up on a freezing Tuesday night. Swift Heat had an engineer at my door by 10am next morning. Fixed in an hour, fair price. Will absolutely use again.

Got our heat pump installed through the government grant. Swift Heat handled every bit of paperwork and saved us £7,500. Brilliant from start to finish.

Third year in a row using these guys for our annual boiler service. Always on time, always tidy, always honest. Wouldn't go elsewhere.
