I moved to Bridport eight years ago, since when I have fitted 119 (and counting) solar hot water systems. I also upgrade, repair and service existing systems, as well as help and advise DIY-ers to fit their own.
I operate under Dorset County Council's 'Buy with Confidence' scheme. All my customers are given a (postage-paid) feedback card to send to the Trading Standards Service, where my approval rating is monitored. Visit www.buywithconfidence.gov.uk for my listing (search for 'solar' or 'green services') or www.dorsetforyou.com for details of the scheme.
