I've got a lock up with an office attached to it which costs me £300 a month,
The broadband is £10 a month and we haven't spent £20 in electric since we moved in 3 months, electric is paid for by the means of an electric card.
The office came fully furnished with office furniture and has heating/air conditioning,
We have no contract on the office and can leave whenever we wish, like wise they could move us on I suppose.
The massive plus point to this is we've got our home life back as the business had taken over our house.
