The company won the accolade, which was awarded by independent environmental group The Green Organisation, at an awards ceremony at the House of Commons last week (17 November).

Roger Wolens, national organiser of the awards, said: "To show continued interest in environmental issues during the current financial climate shows great foresight and they deserve the recognition of being Green Apple Award winners."

Cloc environmental champion Oliver Thomas said receiving the award was "a proud day for the company".

He said: "It is fantastic to know the great efforts that we are making every day are being recognised in this manner and that the confidence we have shown in our policies and procedures is being justified."
