What our customers say

Nine solar panels fitted to a slate residential roof in south London

"Total professionalism from start to finish. I was concerned about having the panels fitted to a slate roof I had fitted seven years ago, but any fears were unfounded. Care and attention to detail should be NextGen's official motto. Tidy, efficient and very pleasant workers. Would certainly use again and happy to recommend to others."

Installation of solar thermal system

"Chris was very helpful in explaining how panels would be installed, was flexible about fitting in with our building works. Very neat and tidy - absolutely no mess or redecoration needed. All seems to be working very well. Always very nice to deal with."

Customer in Richmond, 9 January 2012
Repair to Solar Heating

"The original supplier of our Solar Heating system (Smart Energy) went bust some time ago. The system was producing no hot water and there was an error message on the control unit. Chris came to look at it very quickly. He researched the system and diagnosed a fault in the control and a burnt out pump, phoned for the replacement pump (fortunately they are still available!) and it was delivered to our home the following day. He came and fitted it the next day (Saturday), flushed out the system, replaced the fuse in the control unit and gave everything a very thorough check over. The final bill was very reasonable. Very pleasant chap and he explained it all clearly. Definitely recommended!"

Solar domestic hot water installation

"Very good company to deal with from beginning to end. Price was way below other quotes we obtained, but we now have a high quality solar hot water system.

Complications arising from our antiquated heating system were overcome with no fuss and no extra charge."
