pound coin house

After speaking to four independent companies (including a biomass consultant), we decided to place our trust in ESI Scotland. This decision was based on their knowledge, approachability and a competitive cost. Since we have had our system installed 3 Months ago it has been working extremely well. We have already seen a difference in our heating bills.

We have found all the team at ESI Scotland to be very helpful with all our queries. The installer could not have done more to make sure the interruption to our home was carried out with minimum disruption.

Thank you to the service engineer, who we have had to call upon a couple of times regarding the simplest of troubles and thanks also to the fantastic office staff for quick response to our RHI queries.

We would strongly recommended ESI Scotland for your biomass heating system.

ESI Scotland Ltd provided a great service; from the initial visit right through to commissioning.
Mark was able to answer all of my questions about the technical and economic aspects of a PV installation and made it completely intelligible!
Everything was efficient and smooth, beginning with the quote, then on to the delivery of the system and the installation.
His team were extremely professional, and I  am very happy that I decided to go ahead with this project with ESI Scotland Ltd.

We had a new boiler installed by ESI Scotland Ltd last year and My! What a difference!

The house heats up so much faster than before & my gas bill is much lower than in previous winters.

There was a quick turn around from my initial home report to my install and the surveyor was very knowledgeable and friendly

Highly recommended!
