To help achieve the government’s target for net-zero carbon emissions, UK Prime Minister Boris Johnson wants 600,000 heat pumps installed in UK homes by 2028. However, in 2020, just 38,000 were installed – to combat this, he wants to lower the cost of heating homes.
The Prime Minister recognises that the reason for the low installation rate is due to the high cost of heat pumps. In Parliament, he said that:
“Let’s be frank, these things cost about 10 grand a pop, this is a lot of money for ordinary people.”
One of the most energy-efficient heating systems for residential properties is water underfloor heating, which uses water heated by heat pumps. These use either heat from the air or underground.
The government’s Climate Change Committee wants the sale of gas boilers to cease from 2033. Installing underfloor heating is not expensive, but replacing gas boilers with heat pumps is.
The Green Homes Grant helped with the costs of making homes more energy efficient, but this scheme has ended. Johnson says that he wants the cost of heating homes to be lowered for consumers. UK utilities may move green levies on electricity to gas, which will make electric-powered underfloor heating cheaper to run. The government has not announced a replacement for the Green Homes Grant to help with the cost of installing heat pumps, however.
If a heat pump is too expensive for households, they can install underfloor heating that is powered by gas or electricity. The heating system can be upgraded if the price of heat pumps falls or grants become available.
