Ground Source Heat Pump Costs

How much does a ground source heat pump cost?

The cost of a ground source heat pump starts at £3,510 for the Kensa Shoebox. Project costs vary depending on factors such as the scale of the installation, available land area and how energy efficient the property is. As well as the unit itself, there is also the cost of groundwork and installation.

An income from the government’s Renewable Heat Incentive (RHI) soon makes it worth it. Not to mention the money you save from the low-running-cost and low-maintenance heat pump, which requires no annual servicing.
