What our clients say

“My 12 year old solar system stopped working. DCR predicted from the symptoms that the inverter had probably failed and quoted to replace it with a choice of brands at very competitive costs. The engineer arrived with a new inverter already on the van which had been ordered in advance should it be required. His test of the system confirmed the old one was indeed faulty, but the rest of the system was operating as it should. The inverter was replaced and commissioned on the spot with the installation being a very neat, tidy and professional job. The whole team from DCR were really courteous, helpful and knowledgeable from initial enquiry to fitting. This is a good, honest, competent and reputable company that I would strongly recommended.”

Peter Brunger

“An excellent company with expert staff who provide a first class professional service.”

Mike Kirton

 

“everyone was helpful and polite, involving and informing us at every step, respectful of our property and those of our neighbours and were totally professional throughout”

Tony Watts

“Initial enquiry about the installation of a battery to supplement the long installed solar PV led to a swift home appointment with advice & very helpful explanation of options but with NO hard sell. Fitting date exactly when we wanted, carried out with explanations when sought & cleaned up afterwards. Certainly can recommend the team.”

Keith Marklew

 

“Excellent Service! We are very pleased with how proficient Becky, Dan & the team were with our solar installation. They are a credit to DCR!”

Becca Holdings Ltd

“Solar panels and battery fitted in November. Very professional from initial fault finding visit to completion of the installation. It was good to be able to discuss our needs and be given various options. Communication with office staff was excellent. All the workforce on site were courteous and polite. The work was completed in under 3 days and everything left clean and tidy. Would have no hesitation in recommending the company for this sort of work.”

Kath Hirst

“VERY HAPPY with DCR. Following a careful assessment of local solar providers, I went to DCR for a single project to cover everything (solar panels/batteries/car chargers & extra electrical outlets across the property, such as in the garden) and their work has been exemplary – prompt, courteous and very tidy. The resulting SolarEdge system works well and there were no unexpected additional costs. Snags were dealt with quickly and well. Highly recommended.”

Jonathon Berg

“Had a full solar installation done by DCR found them first class right from quotation to completion very informative and courteous guys, can’t recommend them enough, far more professional than others I had quotes off”

Brian John

 

“One big advantage of DCR is that they have a large enough team to do all the installations of equipment, the electrics and the building work”

Tony Watts

“By the end of week two everything was as good as or better than new and we were very cosy with our new heating, and endless hot water, amazed at how well our panels were generating and delighted with the clearing up process which even included hosing and scrubbing our driveway. As well an excellent installation team the backroom staff at DCR were also very helpful, kind, patient, reassuring and professional on every occasion. In summary we could not be happier with the way everything went and would certainly recommend DCR”

Tony Watts

“DCR have installed us a fantastic Solar edge system. With the rising costs of energy and running costs of our business the investment made will ensure we are able to comfortably trade in the future. From start to finish DCR were 100% responsive at all times and even put a plan in place for us that is yielding us up to 50% savings already. All of the DCR team were on time, polite and respectful at all times. As a business, we couldn’t recommend them highly enough. Thank you.”
