Excellent standard of work
Customer Service
We used Sussex Solar to install both thermal and photovoltaic panels some years ago. High standard of workmanship and very happy with both installations. Andy is reliable, trustworthy and knowledgeable in his field. Recently has both panels serviced with usual excellent customer service, explaining what he had done, state of the panels etc.

Air Source Heat Pump Service and Maintenance
Customer Service
Andy took over servicing our two air source heat pumps and underfloor heating system this year and has been knowledgable, efficient, courteous and good value for money. What is more, when we had a problem (caused by a power cut) one evening, Andy called straight back, reassured us that he could come the following day but in the meantime gave sufficient help over the phone for me to fix it myself, with no charge and a follow up email! Great customer service.

Experts in their field
Customer Service
Our Solar panels weren't working. Sussex Solar diagnosed the problem. Replaced the pump (which had broken), fixed a leak, replaced the fluid and serviced the system. They were knowledgeable, helpful and friendly throughout and completed all the work in one visit.

Great Customer Service
Customer Service
We had PV panels fitted over 5 years ago. About 5 years before this, we had a solar panel installed to provide hot water. Subsequently we have had services carried out, and repairs undertaken. All dealings with Andy have been carried out to a good standard, in an efficient and timely manner. Andy and Amanda are very helpful and personable.
