Client Testimonials

“Got in touch again with Carol at RJ Consultants as just finished a project with building control wanting some documents ready for the following week… The service from Carol was absolutely fantastic! She went above and beyond to ensure the documents were ready before the deadline, squeezing us into a hectic work schedule. I am very grateful for the hard work and help. I would highly recommend RJ Consultants .”
“Carol at RJ Energy has been fantastic at helping me deliver my first Selfbuild. She has a wealth of knowledge and experience but is also happy and willing to give down to earth guidance and tell you when your getting carried away! I would recommend RJ Energy Consultants to anyone!”
“RJ Energy Consultants - really do that job! They are excellent at their work in calculating all the SAP ratings etc and do it at a very competitive rate!.”
This is the first time we have used RJ Energy Consultants and all I can say is it won't be the last....by far the best company for SAP's and EPC's that we have come across.
