Annabelle Perry

PUIG UK Limited

SECR and ESOS Phase 2:Efficient, fast and reliable. Pierre Olivier was engaged as our ESOS Compliance lead assessor and fulfilled the audit to the timescales required. He managed to review the data and compile the report in a relatively short amount of time, to produce a clear set of actions to take away and meet our obligations. Would recommend.

Nicola Newson

Smart GreenTech Solutions assisted with our ESOS compliance. Pierre was professional and thorough throughout the process. I would use Smart GreenTech Solutions again in the future and highly recommend to others.

Pierre is knowledgeable in the field of energy management and provided practical advice in a concise manner during the ESOS Director debrief. Working with Smart GreenTech Solutions was easy throughout the process from initial contract setup, through to planning site visits and invoicing.

Duncan Morris

I contacted Smart GreenTech for advice to determine whether our business fell under the scope of the ESOS Regulations. They reviewed our individual situation and responded promptly with expert knowledge to advise accordingly. I wouldn't hesitate to recommend Pierre and his team.

Smart GreenTech have been absolutely outstanding when assisting with ESOS Phase 1 and Phase 2. Constantly providing assistance, explanations and professionalism, in an area that can be quite complex, Smart GreenTech made being compliant with ESOS look easy! Would definitely recommend!

Mark Gage

Brend Hotel Group

Smart GreenTech provided us with consultancy and design services for a major boiler replacement project at one of our hotels. Their services were very high quality and were invaluable in helping us decide on how we approached our project.


Dan Scotchmer

Pareto Facilities Management Ltd

We have used Smart GreenTech Solutions to carry out various works on our client sites, including lighting surveys, TM44 reports and indoor air quality reports. Pierre is always professional and responsive and provides quality information in a format that is easy to understand. He acts as an extension of our own organisation, to the point where we are happy for him to carry out the surveys and interact with the client directly, and without supervision from us. Smart GreenTech Solutions are a company we will continue to go back to, and would highly recommend to any other organisations looking for the type of services they offer.
