Rayotec ltd is frequently praised for professional, knowledgeable and friendly service, particularly for electric underfloor heating and solar installations. Customers value clear advice, tidy and efficient workmanship, responsive communication and heating that performs well, while product support and delivery also receive positive mentions. A few reviews raise concerns about app or thermostat guidance, connectivity and some solar maintenance call-outs, with occasional criticism of pricing and follow-up.

I have used the electric underfloor heating mats on all my Garden Rooms over the past 3 years and have not had a single issue with the product or delivery. Excellent all round company.

Does it work? yes. Was it installed as I would expect, yes! The Team was professional etc The only issue was setting up the "App" yes there is an app. It is a Free open source app which means that instruction and guidance is awful and is still showing some things in Spanish "periodo". I love our underfloor heating and having a radiator free house. So for that I thank you

The engineer came and inspected my inverter, checked that it was OK and reported that there was nothing wrong with it and no further action required. All done within 1 hour.

Rayotec were prompt, efficient, friendly and at a sensible price. They replaced my faulty solar inverter with a compact modern unit which has worked well ever since. Can't fault them.

Useless firm - they don’t actually do any software repairs or reboots. And they don’t stock dataloggers or replace them. Waste of space
