Natasha Ginks,

if you’re considering a ground source heat pump, consider it further because so far it’s brilliant. I couldn’t recommend Iso Energy more highly – they delivered an excellent system on time and on budget. Read more about our experience in green renovation on our website

Charles Linney, Linney Group

When contemplating a major investment on our site, the board needed to find a company we could work with and trust. From understanding our thoughts and requirements, delivering a system within a tight deadline, to attaining the necessary accreditation, isoenergy proved to be a competent and reliable partner.

Graham, CHET Centre

It became clear from my very first meeting with the Iso Energy representative that he knew exactly what he was talking about. His knowledge and expertise in this field was clearly evident throughout the meeting. This immediately instilled my confidence in the company’s ability to deliver exactly what our business required. I was further impressed by their professionalism, competence and general work ethic. They were always on site when they said they were going to be there, the work was completed to a very high standard and on schedule and their after sales service is without fault. I would definitely recommend Iso Energy to any business or home owner who not only demand but appreciate a professional service throughout.

Thank you, can we join the list of very satisfied and happy customers please?

Whitehouse Farm
A very professional, efficient and courteous service. One could ask for nothing more.
Stephen Israel
ISO Energy installed a Ground Source Heat Pump system in our house in the Summer of 2013. They are a company that dot every i and cross every t. They have polite, professional and efficient workmen, use the best quality hardware available for the job, and we were very happy with the installation. Any problems or queries were dealt with immediately, and I would without doubt recommend them as an installer of GSHP. And the house is warm!
Sabrina Wisely
A big thanks to your engineer who not only did a fantastic job, but was also very good at explaining the work involved.
Rick Englert
Thank you for our wonderful water source heat exchange system which is now keeping the whole of our rather large house very warm and cozy 24 hours a day, heating our indoor pool and giving us plenty of hot water for our showers, baths and sinks. A miracle of modern technology! And the fact that it should use 60% less energy than our previous oil fired system is extremely gratifying for our pocketbook as well as our carbon footprint. Thank you for making it all possible.
Peter Hills
I am pleased with the way the system has been installed and the helpful attitude and skill of your technicians on site.
Peter Costain
I would like to congratulate you on the way your team has performed here at my house. I have been extremely impressed and believe they are very professional. I have already recommended you to one Estate Agent who covers a number of properties in this general area.
Peter Bosson
ISO were good and professional with a very good standard of on site installation.
Nicole Smyth
We continue to be amazed and thrilled by the installation.
Nick Shaftesbury
I think everything was explained really well and I am particularly happy with how the heat pumps are performing.
Mike and Lesley Dickinson

Isoenergy demonstrated to us that they are truly customer focussed, intent on doing the best they could for us. We never felt pressured into doing anything we weren’t completely happy with. They were always open to feedback. We felt totally confident about their technical ability. They were prepared and able to offer alternatives that would better suit our needs.

Martin Holland
Thank you so much for a successful installation at my property. Thank you to the whole team, who designed, installed and commissioned the system so successfully. I will certainly recommend you to anyone who asks for a good renewable energy firm.
Mark Gidney
Please tell your service engineer that we were very pleased with the way he went about looking for the problem and hopefully solving it. He showed good initiative and did much better than our plumber or the underfloor heating person!
John Sinclair
Nice and cosy at the barn, this ground source has been one of the best things I ever had installed.
Jo Parrilla
The gentleman who serviced our system is a first rate engineer and did a very thorough check. Isoenergy should hang on to him!
Jason Smith
We were very happy with the efficient and professional service which we received from the team at isoenergy and we would like to thank you all.
James Doran

I would like to thank the engineer who attended site last week, he did a great job and is a credit to your business.

Graham Still-Blundell
Just wanted to say thank you very much for your perseverance regarding our application for non-domestic RHI. You probably know but have just had confirmation of our acceptance onto the scheme. It was a long haul to say the least but I couldn't have done it without you so thanks a million, you're a star!
Francheska Pattisson

Many thanks for a fantastic, efficient and friendly service. We are really pleased with the new plant room layout – and the heat generated by it! I never thought I could be so excited by heating plan and its beauty. We particularly appreciate the efforts isoenergy went to fit us in at such short notice, and how hard the engineers worked each day to get the job done; they were also thoroughly professional, courteous and sensitive to family life going on around them.

Eileen Jamieson

Whilst it's still fresh in my mind I thought I should drop you both a note to thank you and your teams for the professional service we have received. Both Jamie and I have commented on how thorough, reliable, polite and knowledgeable your staff have been. Congratulations to you guys for putting such good teams together and please pass on our thanks to them.

Charlotte Wood

I had my first bath in the cottage this morning - beautifully hot as you confidently predicted. The advice and care we have received from all the iso team has been wonderful and I'm sure the excellent service will continue. Thank you all so much.

Bob Nunton

Everyone on the team was friendly and enthusiastic throughout and a credit to you.
