Kensa pioneered the adoption of heat pump technology in the UK. Combining quality components, precision engineering, talented production staff and a state-of-the-art test facility, Kensa‘s heat pumps provide market-leading performance. Beyond manufacturing heat pumps, we work with many installers, specifiers and housing providers to deliver exceptionally well-designed systems which out-perform the market.

We pride ourselves on the quality of our installation support. As an MCS-accredited manufacturer and installer, Kensa is intimate with every project, providing a ground array design, guidance on appropriate heat distribution and hot water systems, and complete technical support.

Kensa heat pumps are compact, durable, easy-to-install and supplied with an exceptional warranty and after-sales support. We also supply all of the accessories including manifolds, slinkies, anti-freeze, buffer tanks and cylinder.

Working with Kensa & its product range


Did you know?

Our heat pump factory and offices in Cornwall are heated using Kensa ground source heat pumps. Being based on a former mine site, our factory utilises water in a disused mine shaft as the heat source for our heat pump!

What does 'Kensa' mean?

The name “Kensa” (KEN-zah) comes from a Cornish word meaning “first”. Kensa has lived up to its name in many ways:

  • The first and only dedicated ground source heat pump manufacturer in the UK, established in 1999.
  • The first to create a ground source heat pump small and quiet enough to be installed inside flats and apartments, the Shoebox range.
  • The first to install shared ground loop array systems with individual heat pumps inside properties, providing ultra-low-cost and low carbon communal heating to communities.
  • The first to develop a dedicated system manager unique to ground source heat pumps, Genesis.

What is Kensa's history?

Kensa was founded in 1999 by two former marine engineers – Richard Freeborn and Guy Cashmore – who, having spent years working on heat pump installations for luxury yachts in the Mediterranean, recognised the opportunity to transfer the technology to applications closer to home. From early on, they also recognised that the key to success was to come up with a simplified and less costly alternative to what they considered to be often over-designed and unnecessarily complicated imported products.

Privately-owned and headquartered in Truro, Cornwall, the Kensa Group is now a fast-growing collection of award-winning businesses involved in the manufacture and installation of ground source heat pumps and the ownership of associated underground infrastructure.

The Kensa Group is well-placed to help to meet the UK’s 2050 net-zero carbon targets.

Kensa were realistic and honest in their sales pitch. Numerous sales persons I met from other companies were clearly not as well informed!"
