Ground Source Heat Pump Installation Cost & Prices 2023

Heat pumps provide an innovative, efficient, green and sustainable way to heat homes and they’re rapidly growing in popularity. 

Heat pumps are incentivised under the government’s Renewable Heat Incentive (RHI) – the government is actively encouraging more homeowners and developers to use heat pumps. 

By fitting a ground source heat pump to your home, you can enjoy reliable, low-maintenance, low-carbon and low-cost heating all year round. They are some of the most efficient heating technologies around today. 

This article will cover the costs involved in installing a ground source heat pump, factors affecting the cost and other common questions around installing a ground source heat pump.
