I very rarely leave reviews which is poor really as I rely on them. It's the extremes of service that spur me to do so and in this case I have to say that Andy Perkins and his team at EZ solar deserve every credit. Andy heads a thorough company who are well versed in renewable energy and who clearly have a deep knowledge of the field. A lot of cowboy companies sprang up as there was fairly hefty government subsidiary that could be abused but I can hand on heart tell you these guys are not that. At all. They serviced and repaired a poorly maintained solar thermal system on a house we bought and then installed with solar PV and a biomass boiler. There have been a couple of teething problems but to be fair they did basically gut a coal fired central heating system and rebuild from scratch and every (small) issue has been addressed immediately with, as a bare minimum, a next day fix. I am happy to put my name to a recommendation of EZ solar and of Andy. I genuinely believe you can't go wrong with them.
