Cherry Blossom View is a new 75-home neighbourhood in Midsomer Norton, Somerset, that developer Wain Homes designed to prioritise sustainability and energy efficiency. It comprises a variety of traditionally built family homes, each equipped with solar panels and electric vehicle charge points and leads the way for the local area as the first development to use ground source heat pumps over gas.
This project was completed by UKPS, which was fully integrated into the existing Last Mile group in March 2026. While the company name has been rebranded to Last Mile, the team, expertise, safety and commitment to quality service remain the same.
The project required High Voltage (HV) and Low Voltage (LV) electrical infrastructure with the installation of a 315kVA substation and the piping, 39 boreholes and manifolds forming the shared ambient heat network. This created challenges both in constructing the new assets and in coordinating the various stakeholders involved in the build programme.
Our team worked closely with the developer to design and coordinate all onsite utilities with multiple incumbent utility providers including: National Grid, South West, Bristol Water and Wessex Water. The construction programme was complex, particularly with the added challenge of securing a New Appointment and Variation (NAV) licence for clean water and wastewater. To ensure timely connections could be completed, construction of the assets continued whilst the NAV process continued in parallel and once the licence was granted services could be quickly connected.
To meet Future Homes Standard and reduce emissions from homes by 75-80%, Wain Homes sought a cost-effective alternative to gas heating and chose to pioneer its first ambient heat network using ground source heat pumps.
To help the developer overcome the capital costs of the ambient heat network and encourage the adoption of the low-emission heating technology, we provided a unique forward-funding model to Wain Homes, through Last Mile Asset Management. This asset value agreement enabled the heat network to be delivered at zero cost to the developer, removing upfront costs and supporting early adoption of this sustainable heating infrastructure.
By value-engineering the utilities routing, UKPS minimised trenching and installation time, saving the developer time and resources.
In line with the developer’s aims, our heat network substantially reduces emissions at the site while saving residents money. The network extracts four times more energy from the ground than the electricity it uses, offering an 80% emissions reduction compared to gas heating, and a 54% reduction compared to air source heat pumps (ASHP). Homeowners benefit from a fixed rate tariff with low running costs and long-term energy efficiency.
Once we completed and energised the utilities infrastructure, Last Mile Asset Management adopted the connections and infrastructure, managing long-term performance. Last Mile Heat, the heat network management arm of the Last Mile group, now operates and maintains the heat network, providing 24/7 monitoring and maintenance, customer service support for residents, and billing management. Delivering this ambient heat network has enabled the developer to build energy efficient, Future Homes Standard dwellings ahead of it’s implementation.
