Apologies Neil. I was going to ask you about your water meter Factor did you go ahead with it. It has halved my previous bills. Should have done it years ago.
Sorry for deviating neil2 but I think your clue has been answered now.
Yes emeritus. Even though mrs factor wouldn't give up her daily bath and waters the hanging baskets and tubs with tap water in summer (while I try to get away with dirty washing up water when she's not looking) our bill has halved. Excellent result
