National Girobank was a British public sector financial institution run by the General Post Office that opened for business in October 1968.

[6] The Post Office bought land on the site of sidings of the North Mersey Branch railway.

[6] The National Giro was the first financial institution in Europe, and probably the world, to be established from the outset to be fully computerised.

[1] The Alliance & Leicester won a bidding process for the Girobank operation in 1989 after the Conservative government privatised the bank, as part of a programme of sales of state-owned businesses.

The Girobank wording continued in use on some credit slips intended for paying bills, along with the Alliance & Leicester "plus" logo.
