- Kensa embraces the Committee for Climate Change’s (CCC) recommendation that gas boiler installations should be outlawed in new homes by 2025.
- The report recommends mass deployment of heat pump infrastructure to replace new gas grid connections if we are to meet our legally-binding climate change targets to reduce greenhouse gas emissions by 80% by 2050 (on 1990 levels).
- Kensa claim ‘London is leading the way’ with its adoption of SAP 10 carbon intensity factors impacting heating specification.
- The emergence of entities to fund, own and maintain the ground arrays in return for an annual connection fee will remove developers of cost burdens beyond the current subsidy.

Kensa’s CEO Simon Lomax says:
We wholly embrace the CCC’s call for urgent action and would hope the Government would look to introduce this requirement before 2025. The report identified a skills gap, but the knowledge and technology is already here and is deploying at scale in more challenging retrofit applications.
Kensa recently installed England’s largest residential ground source heat pump installation at eight high-rise tower blocks owned by the London Borough of Enfield. This project featured the shared ground loop array infrastructure which effectively takes the place of the gas network and serves an individual heat pump and hot water cylinder installed inside each dwelling.
Government has delayed the introduction of any effective regulations that will encourage the deployment of heat pumps in new build housing. Thankfully, the Greater London Authority (GLA) has lost its patience and now requires planning applicants to base their energy strategies on the forthcoming carbon intensity factors proposed for the next generation of SAP, the software that demonstrates compliance with building regulations. As a result, London will lead the way.
The expected increase in heat pump deployment prompted the GLA to commission a 2018 report, ‘Low Carbon Heat: Heat Pumps In London’. Kensa’s shared ground loop infrastructure is described in the report as ‘the most efficient, lowest carbon, and lowest cost solution when utilised in new build houses compared to various air source, direct electric, gas and CHP configurations’.
