Avoid Glow Green in Bournemouth. They have an office in Bournemouth but offer their services Nationwide. They use Sub Contractors that they know nothing about and some of these fitters know nothing about Solar Panels etc. I used Glow Green because they promised that they could complete my Solar Panel fitting within a 2 month timescale. Plus they are covered by an independent body called HIES. They let me down, time after time. Telling one lie after another. Promising timescales that they could not keep. Our experience was a weekly torture which lasted a whole year when it should have only taken 2 days to fit. They are not the cheapest but they came across as the most competent... That was a very costly assumption of mine. It cost me over £2,000 on top of their already high estimate. Don't trust them and definitely don't let any of your friends and family go anywhere near them.
