A smarter way to heat your property
Heat pump installations can make a real difference if your current system is costly to run or starting to show its age. Terra Therma Renewables Limited installs both air source and ground source systems across the South East, East Anglia and beyond, helping you choose the right solution for your home or business. We also provide heat pump servicing to keep your system operating efficiently long after installation, alongside air conditioning solutions for reliable year-round comfort.
Instead of burning fuel to create warmth, heat pumps move existing heat, helping to reduce running costs, lower carbon emissions, and improve EPC ratings. We guide you through every stage of the process, explaining what to expect, how long installation typically takes, and how to get the best long-term performance from your new system.
Why renewable heating makes sense in the long term
Lower running costs are only part of the picture, because a well-chosen heat pump can also give you steadier comfort through the year. We can pair efficient heating with the sort of ongoing aftercare that helps protect performance over time. European-manufactured systems bring proven reliability, and regular servicing helps keep everything working as it should. For many properties, switching now also means being better prepared for changing energy costs and future efficiency standards.

New heat pump and full pipework renewal.
I looked long and hard before finding the right company to do this work for us. When we found TT, we knew we'd found the right place.
Mark, Evan and the team were beyond helpful and always took the time and trouble to explain everything to us, especially as it was our first heat pump.
Everything was done, exactly as they'd promised and the work on site was carried out to a very high standard by the team, led by Brad. The paperwork side of things (grant, certification etc.) was all taken care of for us and it all arrived when it should. Since then, if we've needed any support, they've continued to be there for us, including answering our daft, non technical questions! Can't rate them high enough.
