Services
Ground Source Heat Pumps
We design and install ground source heat pump systems that extract underground thermal energy for commercial and residential properties. Our monovalent systems provide both space heating and domestic hot water using underground collector loops or boreholes. The technology delivers 4kW of heat for every 1kW of electricity consumed, maintaining consistent performance across seasonal temperature variations.
Air Source Heat Pumps
Our air source heat pump installations extract ambient heat from outdoor air to provide renewable heating for domestic and commercial buildings. These systems operate efficiently even in low temperatures, reducing heating bills by 3952,000 annually compared to conventional oil or LPG systems while maintaining minimal visual impact.
Heat Recovery Systems
We integrate heat recovery ventilation systems that maintain indoor air quality while reducing energy consumption. The technology captures waste heat from exhaust air to pre-warm incoming fresh air, delivering energy savings while meeting building compliance standards.
District Heating Projects
Our district heating solutions centralise renewable heat generation for multiple properties using interconnected pipe networks. These systems combine ground source heat pumps with thermal stores to provide consistent low-carbon heating across housing estates, commercial parks, and public infrastructure.
Consultancy
We provide technical consultancy for renewable heating projects including feasibility assessments, DNO applications, and funding strategy development. Our experts guide clients through planning requirements and compliance protocols while optimising system design for specific property characteristics.

Great sales Nice Installation engineers who came to install the system very helpful & willing, With a few teething problems which needed adjustments (to be expected) Sadly the main Heat Pump failed after 130 days not that cold outside either, no heating no hot water, the main pump insdie the outside unit had failed (bearing), not a part they hold in stock , plus they clam the warranted is with the manufacture ,(this is wrong) due to this they can only act on manufacturer instructions, no pumps are held in the UK, (I wonder why, are they failing) these have to come from Europe, taking a week to

Finn Geotherm installed our air source heat pump, and we wouldn't hesitate to recommend their services. Everyone we dealt with was friendly, professional and efficient. They went to great lengths to ensure that everything was done to the highest standard. At one point, they decided the electricity cable could be better located, to make it as unobtrusive as possible, so went out of their way to reroute it. The office staff are equally helpful and friendly, and their advice has been invaluable in helping us gain our RHI payments.

From the first phone call to the last, I can't fault Finn Geotherm. The office staff were amazing and nothing seemed too much trouble, no matter how many questions I asked. They always got back to me promptly with any information I was after. The survey was undertaken promptly and was very informative and well detailed. A great pack was sent shortly afterwards and was very helpful. I had a 14kw electric boiler and replaced it for the air source. I am already feeling the benefits from it. When I was told the unit would be quiet, it was still a pleasant surprise to realise they weren't joking

Absolutely a fantastic company!! From start to finish very professional, always there to help and give advice. The people are all very lovely and friendly. The team are like a family! Great products, I love my air source heat pump. I also like the fact that I'm doing my bit for the environment and for myself as I will save money. Having home improvements can be stressful but having Finn Geotherm was actually a pleasure, they made the whole experience easy. Thank you all.

Critical:Responsiveness
Finally gave up waiting for the quotation 2 1/2 months after getting an estimate. We were ready to sign but they seemed completely disinterested.
Went with another supplier.
