I love the technology – the idea of harnessing free heat from the ground is so simple and Kensa’s kit is top of the range. I often show visitors our heat pump unit and they are blown away by the efficiency and simplicity of our heating system. I’m really pleased with how it’s working.

Richard Waterstone, Homeowner

The money we get back from the RHI more than offsets the capital costs. If it makes economic sense then it would be lunacy not to do it!

Alistair Mackintosh, Homeowner

I loved the service I received from Kensa; they gave me lots of information and constant support. They went above and beyond in terms of the customer service.

If I was to offer advice to anyone thinking of installing a ground source heat pump, I would say don’t hesitate, but definitely talk to Kensa – they are experts and know what they’re doing.
