SOLAR SENSE UK in Brockley, Bristol

I engaged SolarSense-UK to perform a service of my solar thermal panels, in October 2021. The engineer was very polite, tidy, and completed the job - within thirty minutes and charged £230 (not cheap). The system didn't function over the winter months, and on the first sunny few days in March 2022, the system flashed up with an error. SolarSense didn't return calls or emails, and I engaged a different engineer, who analysed the system and determined that during the service, the flow valve had been left closed. When I contacted SolarSense, they refused to help, stating that too much time had passed, and quoted me a minimum of what they charged for the service to even VISIT.
