5/5

Good service and very flexible on timing of visit. A bit expensive for the time the service engineer was on-site, but if you average the cost out over the 5 years since the last service (and the next service will be in 5 years), it then becomes reasonable. Peace of mind is worth paying for.

Just completed our five year service on the solar water system. Refreshing to have pleasant service engineer that actually turns up on time and completes his job in a friendly and efficient manner. Thank Kevin and we'll done Sunuser.

The engineer apologised for arriving early for our five year service. He was courteous, friendly and respectful to us and our property. The whole service was completed in an efficient and professional manner with a full explanation of all the procedure and the results. Very satisfied with all the work.

Seamless, professional and friendly from start to finish. I made my payment electronically, but I was so pleased to see that they offer an option over the telephone as well, a service which is often lacking from other companies.

The company has been extremely helpful with regards to assisting me with 2 different solar systems installed at my late Aunt's home whilst I have been selling the property. They are always prompt for appointments and keep you well informed.

Had the system 21 year's now

Had the system 21 year's now. Hard sales pitch, to be expected installation fine, although a couple of months later realised a number of items Has been stolen from my loft. Has worked well until 18 months ago when it stopped working. Every part via the tank had to be replaced! A few months later realised there was a.leak and system had stopped working again. Phoned Sunuser and was told a prv needed to be fitted, suggested that it had been fine for 20 years and if one was needed why didn't they fit one on installation.

This company sent a buffoon to do a simple job of changing fluid. He ended up going into a part of the loft where he didn’t need to be and ended up breaking water pipes. It flooded down into the kitchen of my bungalow, ruining insulation, blowing the electricity, covering the hob in slime and soaking towels I used to mop up the water. The place looked like a disaster zone and he left everything trying to blame me in 3 different versions. On said buffon leaving I noticed he had also spilt fluid all up the hallway. They had the nerve to send 2 demands for bill saying not their fault as all automatic. I sent pictures of the devastation left behind and a full report, they said they would look into it. I waited until the forecast of getting colder and emailed to say I would employ someone to do the work, I have never heard a word from them. Avoid this company like the plague

Our predecessor here had roof solar panels installed bt this firm. They were inefficient and broke down several times. It was uneconomic to maintain them. When we had our roof replaced Sunuser charged us £1800 to have the panels removed along with the pipework and wiring. The latter was not done and we had to employ another firm to get this done. Sunuser have not replied to our request for reimbursement. Please do not use this company especially if you live in the south.
