Thanks all you have been very helpful 8-)

Hi all I was just wondering if anyone could help? We have prepayment meters for both gas and electric and both with British Gas. They were in the property when we first started renting it so have carried on with them. Does a person have to come out and read them? I am sure I read on their website that we don't need them to as it is done automatically via the card and stick thing (this was september 2009). I am sick and tired of people knocking on my door - I won't let them in as I don't trust them and on pay as you go phone with minimal credit to ring and check their ID. Thanks for reading and I look forward to your response
