Our clients love us…

Our dedicated service has earned us a 5-star rating on Google reviews from 20+ clients.

With Natalie’s guidance and expertise on design issues and material choice we have achieved a 100% reduction on TER. An unparalleled superb service. RS Energy provided an efficient and professional service. Natalie was very pleasant to deal with and helpful throughout. I wouldn’t hesitate to recommend RS Energy.

Mark Washer

For a mere property developer, Part L of the Building Regulations can be rather overwhelming, however, when you have Natalie of RS Energy to guide you through it, what seems an enormous hurdle, disappears. To anyone and everyone who encounters the complexity, to what many of us would consider the irrelevance of outdated Part L, I cannot recommend Natalie high enough to help navigate you through its complexities. In a word, she is phenomenal.
