Loyalty card scheme aims to boost take up of energy saving measures

Loyalty cards have been around for ages. Most airlines and supermarkets have them. But so far, they haven't played much of a part in the energy market.

Conservation officer asks home owner to remove solar panels

Solar PV is a permitted development, however that doesn't stop problems with planning cropping up. Individual councils are left to interpret the rules as they see fit.  We have just heard of a recent example in Dacorum Borough Council in Hertfordshire. A YouGen reader had a 3kw system instal…

Solar panels are one of the most desirable 'deal-sealers' for people buying a new house according to new research.
