Private Housing New Build
Profitably balancing build costs with carbon compliance, conscience, and end-user running cost considerations can be a complex juggling act.
Thankfully, Kensa’s Funded Shared Ground Loop Arrays offer developers renewable heating solutions that meet increasingly stringent carbon compliance building regulations, with the added benefits of exceptional efficiencies, sustainable merit, and the lowest running costs and carbon emissions.
Ground source for the price of air source
Our innovative model sees the ground array infrastructure fully funded, owned and maintained by Kensa Utilities in return for a modest connection fee. This leaves the housing provider to just fund the heat pumps (which are sold with the property and maintained by the purchaser).
This eliminates what is often the key barrier to installing ground source heat pumps – the expense of the ground array. It also mimics long-standing and familiar arrangements in the gas sector, with the underground infrastructure owned and maintained separately from the heat pump installed inside the properties.
This arrangement allows new build developments to access the unique benefits of low carbon, energy-efficient ground source heat pumps and Shared Ground Loop Arrays for the same price as air source heat pumps.
We fund the infrastructure, you pay for the heat pumps
The below outlines the mechanism for developers and property owners wishing to utilise Kensa’s fully-funded Shared Ground Loop Arrays:
Green Heat Network Fund (GHNF)
This scheme intends to help new and existing heat networks to move to low and zero-carbon technologies. The fund is anticipated to run from April 2022 to November 2024.
Aimed at developers and investors in low-carbon heat networks, such as Shared Ground Loop Arrays, the objectives are to achieve carbon savings, increase the amount of low-carbon heat utilisation in heat networks and help prepare the market for low-carbon regulation.
DISCOVER THE GHNF
Kensa’s innovative Shared Ground Loop Arrays link a series of boreholes to multiple properties, including flats, via an ambient temperature distribution system.
Each property then has an individual Kensa heat pump wired to their own electricity supply, which upgrades the low temperature ground heat for heating and hot water within their dwelling.
The advantages of Shared Ground Loop Arrays in new builds:
- Exempt from Heat Network Metering & Billing Regulations.
- Extremely low CO2 emissions;
- Easy carbon & building regulations compliance.
- No NOx, SOx or particulates emissions.
- Lowest energy bills – slightly lower than mains gas, significantly lower than air source heat pumps, LPG & oil.
- Householders able to switch energy suppliers.
- No district heat losses.
- Potential for free summer cooling.
- Scalable and flexible district size can be deployed in sections as the development progresses.
- Ultra-efficient and reliable.
Compared to various air source, direct electric, gas and CHP configurations in new build houses, shared ground loop arrays are the most efficient, lowest carbon, and lowest cost solution.

Properties featuring Kensa’s Shared Ground Loop Arrays will provide end users with numerous unique benefits over traditional Heat Networks with minimal after care requirements:
Lower fuel bills
GSHP’s produce 3-4kWh of heat energy for every 1kWh of electrical energy used, making them 300-400% efficient. Compare this to a typical boiler, which is just 90% efficient. Kensa’s ground source heat pump systems offer the lowest fuel costs.
Because a GSHP extracts so much “free” energy from the environment, this enables CO2 emissions to be lower than any other type of heating system.
GSHPs don’t require annual servicing or maintenance, and have an expected lifetime of 20 years.
With an individual ground source heat pump in each property, homeowners are in complete control of their own heating and energy bills, enabling easy energy tariff switching and payment only for their own heat consumption.

Free cooling & no overheating
With heat being generated at the point of use (inside each dwelling) the ‘heat’ circulating the property is low temperature, therefore there are no heat losses from the system to contribute to overheating in risers and corridors. The low temperature system also allows for free passive cooling to be introduced, creating a comfortable living environment all year round.
Year round supply
1m below the surface the ground temperature remains a fairly constant 8-10°C all year round, ensuring your heat supply is constant and reliable; unlike air source heat pumps, which are impacted by external fluctuating air temperatures causing higher bills when heat is most needed.
