* The Post Office in Castle Street.
* The Post Office could move to nearby Stan's store.
The service, subject to a successful public consultation, will open as a new-style main Post Office branch.
The move is part of major three-year modernisation programme across the Post Office network designed to make it easier for customers to do business, through longer opening hours and modern open plan environments.
The investment programme, the largest in the history of Post Office Ltd, will see around 6,000 branches (about half the Post Office network) converting to new-style branches.
The Post Office, now independent of Royal Mail, is the largest retail network in the UK, with over 11,500 branches. It is also one of the fastest growing financial services companies and is developing its online and telephony services.
Post Office Regional Network Manager for Wales, Tony Jones said: “I am delighted to announce news of an important investment in our service in Llangollen.
"We know how important the Post Office service is to the community and we feel sure that our customers old and new will welcome the longer opening hours and modern open plan format. This move will help secure Post Office services in the town for the future.”
Mr Jones added: “Post Office Main is a new concept for delivering Post Office services, operated from a combination of screened and open plan counters in an established shop, with key Post Office products and services available alongside retail transactions during extended opening hours.”
Post Office customers will benefit from extended opening hours provided by the new retailer with the introduction of late night and all-day Saturday and Sunday opening.
The opening hours will be 8am-9pm, Monday to Sunday, offering customers an extra 45 hours a week in which to access Post Office products and services.
During the public consultation Post Office Ltd says it welcomes feedback on any issues customers would like considered before a final decision is taken on this proposal. The consultation will close on January 18, 2013.
