We had a 5K solar panel roof system installed, along with a battery and an Eddi diverter. EVR were very helpful and informative during the quote stage, and talked us through the various options, explaining how things worked. The installers then turned up on the date agreed and on time, were very helpful and polite, and cleaned up well at the end. Clear information was provided when the installation was complete, and all the necessary documentation, certificates etc. then followed shortly afterwards. We had a few queries afterwards, which is only to be expected, and these were answered very swiftly and helpfully. Even when asking for general advice on things 4-5 months afterwards, a swift and informative reply was given. EVR know what they are talking about, and have been extremely helpful all the way through the process, and with good customer care afterwards. We would definitely recommend using them.
