GTC has partnered with the Kensa Group to deliver a low-cost renewable heating and cooling solution for tens of thousands of new build homes a year, introducing the Networked Ground Source Heat Pump solution.

This solution offers a clean alternative to gas, which is planned to be banned in new build developments from next year under the Future Homes Standard, requiring all new homes to have low-carbon heating. The Networked Ground Source Heat Pump solution provides reliable home heating and hot water through a ground source heat pump installed in each property, connected to a shared network of hidden underground pipework, similar to what is installed for other utilities.

Kensa's compact 'Shoebox' heat pump will fit neatly under the water cylinder inside the home, saving valuable space and eliminating the need for any external kit, so there’s no visual impact on the property. With up to five times the efficiency of gas and a 30% increased efficiency than an equivalent air source heat pump, these ground source heat pumps require no extra electricity capacity, easing developer concerns about site grid capacity.


The GTC and Kensa partnership, the largest to be agreed between a utility infrastructure provider and a UK ground source heat pump manufacturer, will bring significant scale, funding, and technical skill to the deployment of networked ground source heat pumps for the new build market – delivering a complete end-to-end heating, hot water, and cooling solution for housebuilders.

Through this groundbreaking agreement, GTC will provide the funded solution to housing developers, along with the design, borehole drilling, and network installation, which can be implemented alongside the other utility networks as part of a one-stop shop.

Kensa, which has pioneered networked ground source heat pumps in the UK for more than a decade, will add its expertise in infrastructure and design capabilities and supply its highly efficient, UK-manufactured ground source heat pumps to fit each property.

By joining forces, GTC and Kensa will help UK housebuilders and developers transition to a proven, sustainable, low-carbon heating solution in line with the planned phase-out of gas. It will offer home buyers a lower-carbon, more efficient alternative to individual air source heat pumps. The Networked Ground Source Heat Pump solution can also be used to heat and cool any non-domestic buildings within a development.

GTC Executive Chairman, Clive Linsdell, said: "A big challenge housebuilders face is additional grid capacity for low carbon technologies. This partnership brings an end-to-end heat, hot water, and cooling solution with the same power requirements as gas-heated homes. Our working with Kensa provides housebuilders and developers reassurance around the quality of installation and equipment, and homeowners 100% peace of mind in relation to its ongoing operation and maintenance."
