We just wanted to commend your staff for the excellent work they did on our PV installation this week.

Two weeks ago when we sent a request for a survey by e mail, we were called back within five minutes and the survey was booked that afternoon!

- Sue and Graham, Camborne

Great service, extremely professional team, would recommend to anyone

- Mrs Burgess, Wadebridge

Customer service at every stop was excellent, from speaking to customer service on the phone, the person who visited to assess the suitability (who was extremely knowledgeable and helpful), to the person who visited to complete the finance application and the installers themselves were fantastic.

- Stephanie, Illogan

Happy with the service, the guys were really professional and made sure we were happy with everything they did
