Call out charges are very expensive, they came to check my solar heating system, it's just 1 person spent for 10 to 20 minutes quick check and he charged me 120.

It was through reading the reviews on this company that made me contact them to service my solar hot water system. Friendly receptionist, gave me a price and booked me an engineer for following week! Engineer was friendly and cleared up any mess. Will certainly use this company again.

Our 6 year-old south-facing Sunuser panels provide very hot water, yes, but only in full sun. In Winter we might get 55 degrees if it's sunny. In Summer we can get 85 degrees. This brings its own perils - touch a hot tap or pipe momentarily and you will get scalded. So not suitable if you have children. Whatever the season, if it's at all cloudy, we have to put the gas on to get hot water. There's a heatwave just now but the system isn't giving us any hot water and nothing on the control panel says why it's not working. We bought the house with the panels already installed. We would never in a

We had our panels (4 of) installed fifteen years ago. During the warm months the hot water controller from the central heating is off. As a former efficiency engineer what impresses me most is that during the cold months our panels lift the base water temperature in the tank quite a lot - saving on gas usage. Best investment we have ever made.

My wife and I chose Sunuser over 20 years ago to install solar collectors on the roof of our Chichester home. It has proved to be possibly the best home product that we have ever purchased. It has never gone wrong, works as well now (and looks as good) as the day it was installed, and gives us between 1,800 and 2,200 hours of free solar power every year. The more hot water we use, the more we get. The system has more than paid for itself.

We've had Sunuser solar panels since 2003 heating our water in the sunny months so were delighted to discover that Sunuser now do the PV generating system as well and had that installed in 2013. We've really noticed the difference in both our gas and electricity bills which we pay by direct debit. This year we've had a refund from our gas account as we had paid much more than we need to each month, and our electricity account, which was on the debit side, has now become extremely healthy without any additional payment from us. What's more we get a cheque very few months in payment for the electricity
