Kensa Contracting Ltd provides a flexible contractual solution to deliver large scale retrofit and new build projects featuring Kensa ground source heat pumps.
With unrivalled experience and expertise, and a UK wide network of expert consultants and contractors, Kensa Contracting offers a complete turnkey delivery service.
With a dedicated supply chain from the UK's No.1 manufacturer of ground source heat pumps, Kensa Contracting offers a unique and robust holistic service.
Kensa Contracting specialises in the design and delivery of scalable, low cost and low carbon Fifth Generation District Heating and Cooling (5GDHC) networks featuring ambient Shared Ground Loop Arrays and decentralised ground source heat pumps.
Kensa’s Shared Ground Loop Arrays (SGLAs) are an award-winning and pioneering approach to District and Communal Heating without the drawbacks of traditional Heat Network systems.
Kensa's funded arrays are an innovative funding offer that enables house builders and developers to install ground source heat pumps for the price of air source heat pumps.
Government is keen to support deployment of ground source heat pumps via grants such as the Energy Company Obligation. Explore the funding available for heat pump projects.
The impact of changing carbon factors means the cost to comply with emissions reduction targets increases for developers who traditionally specify gas, whilst it is cheaper for those specifying, and using, shared ground loop array ground source heat pumps.
The Public Sector Decarbonisation Scheme is a fund dedicated to heat decarbonisation & capital energy efficiency projects in non-domestic public sector buildings across England.
With an enviable award-winning heritage delivering ground source heat pump projects of all shapes and sizes, explore some of the most popular market sectors to feature Kensa's ground source heat pump solutions.
Kensa’s ground source heat pumps bring social housing communities together to help eradicate fuel poverty using cost effective Shared Ground Loop Arrays, reducing tenant fuel bills and combatting emissions.
Kensa’s Shared Ground Loop Array ground source heat pumps in new-build social housing provide an exceptionally efficient, low-cost and low-carbon heating and hot water system, offering long-term low-maintenance solutions, whilst fully funded mechanisms remove any financial barriers.
Delivering retrofit ground source heat pump installations at scale is key to achieving our carbon reduction targets. By adopting Kensa's street-by-street, area-by-area approach, Kensa is future-proofing our buildings of yesteryear.
Kensa's commercial Plant Room models offer long-term, low-cost and low-carbon heating & cooling solutions on a big scale, with the assurances of a guaranteed source of heat all year round; a great solution for public buildings with a duty of care, from fire stations, to schools, to depots and council buildings.
Kensa works closely with social housing providers to deliver a sympathetic programme of retrofit ground source heat pump installations with minimal disruption and major benefits, reducing tenant bills and making a dramatic impact on fuel poverty reduction.
Approach
By pairing Kensa’s Shoebox heat pumps with Shared Ground Loop Arrays, developments featuring multiple dwellings, including flats, can attract external funders to own and operate the ground source heat pump infrastructure, removing the cost of the shared ground loop array from the housing association. In return, the external funder can charge connection fees if they wish.
System Architecture
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.
Ground source heat pump installations are eligible for ECO funding in retrofit social housing schemes.
ECO places legal obligations and targets on the larger energy suppliers to fund energy efficiency measures in British households.
It is in place to support retrofit efficiency works in the domestic sector, with a particular focus on vulnerable consumer groups and hard-to-treat homes.
Under the rules of ECO, energy suppliers are obliged to fund energy efficiency improvements of their domestic customers’ buildings in three distinct areas; Carbon Emissions Reduction Obligation (CERO), Community Obligation (CSCO), and Home Heating Cost Reduction Obligation (HHRCO).
Subsidies
Split Ownership model
By allowing ‘split ownership’, Government has created a significant catalyst for energy-efficient new build developments featuring Shared Ground Loop Arrays, with costs no longer borne by the housing provider.
This eliminates the key barrier to deployment – the expense of the ground array – and allows Kensa to mimic long-standing ‘split ownership’ arrangements in the gas sector with the underground infrastructure owned and maintained separately from the heat pump installed inside the properties. Kensa’s model sees the housing provider fund the heat pump (which is sold with the property and maintained by the purchaser) whilst the ground array is fully funded.

Kensa Contracting offers a comprehensive information and training programme to support residents, Housing Association staff, project and scheme managers, ensuring all stakeholders are engaged and well-prepared and understand the stages of work involved.
Tenant liaison
This support is absolutely key, both to ensure the quality and sustainability of the installations, but also to ensure that delivery is well-managed and hassle-free. Kensa introduces schemes to tenants to make sure they’re aware of what’s involved in a heat pump installation, what to expect, and how the project will benefit them in the long term.
After Care & End Users
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.
Lower emissions
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.
Minimal maintenance
GSHPs don’t require annual servicing or maintenance, and have an expected lifetime of 20 years.
Energy independence
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.
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.
