Our people

isoenergy team 2022

isoenergy has specific teams that work on various stages of a project.

isoenergy employs over 60 full-time members of staff and that is currently increasing.

Our Consultant Engineers will meet with you at your property to discuss your requirements and produce an initial design and estimate. Once an order has been placed the case file will be handed to the Technical Team who will contact you to undertake preliminary surveys, where required, and will advise on installation dates.

The Technical Team comprises our key designers for the technologies we install from solar panels and battery storage, to air source heat pumps and ground source heat pumps. In addition, we normally assign a dedicated Project Manager, depending on the scale of an installation.

The Project Managers oversee ordering, design, delivery and installation helping to ensure your project runs without delay from start to finish, liaising with other trades on site as necessary.

Our Engineers and Installers are all employed directly by isoenergy to ensure quality of installation. They work together with our Service Department to provide maintenance where required. We currently have four plumbing teams and two electrical teams. We also have two teams dedicated to building heat pump collector arrays in the field. This makes our operation one of the largest in the market enabling us to be more adaptive to your needs.

We have a dedicated Accounts Department, and when working on Listed Buildings, new builds and renovations we can provide guidance on the relevant VAT rates, available grants and subsidies.


Here is a selection of our key, client facing team members.
