Ok the reply I have received from salford council
Dear Sir
The City of Salford took the decision a few years ago to charge an administration fee for processing all certificate applications made by post or by telephone/online with payment being made with a credit/debit card. This is in line with neighbouring authorities who also charge administration fees.
As the turn around for issuing certificates at Salford is very high, usually within 24 hours, we often receive praise for the service we provide and therefore the administration fee is set to cover all costs including postage.
You can however, apply in person for a 2 day service, and just pay the statutory fee of £9.00, and therefore, as it is made clear that the additional £1.00 is an administration fee, and not the statutory fee for a certificate, it is not in breach of any law.
