Jason and his team @ GreenRock Energy come highly recommended,  they offer a wealth of experience and are very reactive in organising EPCs for our Business within such a short amount time, turnaround within a week with certificates produced the following week,  also excellent service from the team in accounts.  I cannot fault the service, five-star ratings.

I’ve worked with Greenrock for many years and their professionalism, reliability, and attention to detail has always been excellent. They deliver on their surveys quickly and accurately every time, and they’re always available to help explain the results in great detail.

The team at GreenRock Energy have provided excellent support in delivering EPCs and improvement modelling reports on several projects over the past few years.
GreenRock Energy perform in a timely and efficient manner, for those seeking reliability and value for money, I can highly recommend this company.

I have used the EPC and improvement modelling services provided by GreenRock Energy on several projects over the past 4 years, I have always found them to be professional, reliable and a pleasure to work with; I would highly recommend.

We recently used Green Rock Energy to renew EPCs across 97 residential properties. Jason and Lorna were extremely helpful in coordinating the assessments, and Mark, the assessor, was flexible and accommodating around tenant access. Great communication throughout and a friendly, reliable service.
