Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 39 years on the register also points to an established business rather than a brand-new one.

Highlights

Serviced my solar hot water system which had developed a fault. Arrived on time and completed the work as requested. Very tidy workman who fully cleared up afterwards and clearly knew what he was about. I had to wait a while for the service as they were booked up but the wait was worth it. I will use them again for the next service

They are a family firm that really cares about their customers. They fully understand that word of mouth is the best marketing tool any company has. They are attentive and efficient and I would not hesitate to recommend them to other customers.

The old 'inherited' Solar Hot Water System was malfunctioning. There was excessive heat build-up in the loft and a 'kettling'cylinder. The old cylinder and pipework needed replacing due to age and leakage' The loft/heat problems were dealt with speedy efficienty. The new copper work and cylinder replacement were also accomplished to a very high standard. Definitely a work of art. Rayotec kept me fully informed with every step of the work, costings, etc. A stream of communication so rarely encountered nowadays and I felt reassured throughout.

Bi-Annual Service of Solar Thermal Installation

Rayotec is one of the few local organisations with the knowledge and skill to carry out maintenance and regular servicing of Solar Thermal Heating installations and this they do reliably and professionally.

Still going strong

Rayotec installed solar tubes for us over 13 years ago. A recent problem, unconnected with that installation which was still working well, required specialist attention which local plumbers were unable to do. It was reassuring to discover Rayotec were still in business - unlike many early start-ups - and able to rectify the situation. They turned up on time, were within quote, clean, and additionally re-fixed a sensor in position that was not requested as part of the job. Well done and thank you.

Great service

Didn't know who to call as had a fault on the inverter. Luckily chose Rayotec. David Merchant their man in the office understood my problem and arranged for an engineer to either repair or replace. I was told the cost and the invert was replaced. Excellent job done, well done. Would definitely recommend the company.

Helpful and efficient

We were alerted to the fact our solar panels were not working when we sent off our FIT reading to the energy company. Looked up companies who may help and found Rayotec. Gave them a call and spoke to David who was extremely helpful and after liasing with him via a few emails and some photos of our system in the loft, he sent out an engineer to check and consequently replace our faulty inverter. All sorted start to finish in 20 days. Very good service and trustworthy firm. Thank you.

Installation of new Inverter fro solar panels.

A company to be recommended. From David in the office, who was endlessly helpful and patient, to the two young men who did the installation, we were delighted with both the customer service and the work done.

Installation of new solar inverter

David Merchant at Rayotec was professional throughout resulting in the replacement of two existing inverters with a single new inverter on time and on budget. In comparison with other installers Rayotec insisted on a site visit to ensure the new inverter was compatible with my PV array. Rayotec were totally transparent about the whole process and the timetable for caring out the work providing regular updates in a timely manner. When the new inverter would not connect wirelessly to my router, Rayotec promptly returned to install an ethernet cable at no extra cost. I could not praise Rayotec more for a professional job well done and great customer service.

Servicing Solar Panel Installation

I found Rayotec on the Internet in 2021 when I needed a new Inverter for the Solar Panel System. They were extremely efficient in arranging a visit of their engineers who diagnosed the faulty inverter and replaced it with a new unit there and then. A few months later they installed a Solar Boost unit which enabled the use of energy from the panels to heat the hot water. unfortunately, the Solar Boot unit failed after15 months. Mr Marchant at Rayotec subsequently arranged a replacement unit under warranty from the manufacturer and it was fitted by their engineer. Throughout my association with Rayotec personnel and their engineers, I have been treated with absolute respect and they have been so efficient.

Great work, quick and tidy

I reached out to Rayotec for help with a failed inverter unit which typically was just months out of its 10 year warranty (not with them). After supplying details of the current system, they advised replacing it with a smaller capacity one, as the existing unit was over-sized. Within a week we had their team around, very prompt and quick to replace the current unit, and test everything was working. Very polite and helpful chaps!

Replaced inverter

Rayotech were very professional in identifying and replacing the inverter in the loft which had caused the solar panels to stop recording.

Very impressed from start to finish.

I was very impressed with Rayotec which I found on Google. I suspected I needed a new inverter for my solar panels. First contact suggested a call out to assess the problem. Their engineer came out on time and was very polite and friendly. It was established that the invert was in fact faulty . Inverter ordered and fitted in quick time 4 days later at a good price. I was able to pay for my purchase over the phone to yet again a polite friendly young lady. Paperwork and photos came back to me in quick time. I would certainly recommend Rayotec and would have no problem using the again.

Disappointing.

Moved into a house with two systems already installed. Called regarding systems was told it needed to be serviced. The first engineer arrived and could not fit into the crawl space. I had to take another day off work as a different engineer had to come out. Then asked for remote monitoring on the pv system, told the engineer had to visit. The engineer on site a few minutes said a cable had been unplugged and I had to contact solax, the manufacturer to access remotely. Wish I was told this on the phone and not charged a large amount for a call out.

Excellent service

My generation meter on the solar panels stopped working but I managed to contact Rayotec during 'lockdown' They made an appointment for an engineer to call and a week before the date he rang to say he had had a cancellation and could he come round in an hour. Two hours later he had found the (expensive) answer to the problem and fitted a new invertor. He was very careful and well aware of distancing and wore a mask. I would definitely recommend this firm to anyone needing this sort of help.

Went above and beyond

I panicked when I thought my inverter on my FIT system had failed. Reza was extremely helpful and gave me much confidence. The quote was reasonable and he was on hand to explain a few questions I had. Although the inverter rectified itself I have no reservation in dealing with this company again as they left a very impressive customer experience
