Switching from a boiler to a heat pump is a bigger job than simply replacing one heating appliance with another. Before installation begins, an installer needs to work out how much heat your home loses, whether your existing radiators are suitable and where components such as the heat pump and hot water cylinder will go.
The good news is that the work itself may be relatively quick. According to Phil Steele, future technologies evangelist at Octopus Energy, a typical heat pump installation takes between two and five days. However, the exact timeframe depends on the property and how much work is required.
