Jag Singh, who runs a Nisa Local in Great Barr, Birmingham, wants to know if anyone has ever had an energy efficiency interest-free loan from the Carbon Trust. He knows the theory - that air conditioning, heating, lighting and refrigeration may qualify for the loan - because he has the info pack, but before he goes ahead with two new remote dairy cabinets he would like to know how it worked out for others. I'd like to hear, too. Contact me at the usual telephone number, fax or email.
