The Santander branch at the Diamond - wrecked in a bomb blast in May - is to re-open for business next week.
The new-look premises will open at 9 am on Tuesday.
The bank was extensively damaged when two masked men threw a bomb into the building in May. No one was injured in the blast.
In a call to the ‘Derry Journal’, dissident republicans said they carried out the attack.
The Diamond branch, which has 10 staff, was a former Alliance & Leicester outlet and has occupied the site for more than 30 years. It was rebranded to Santander in November 2010.
Since its closure, Santander has used the opportunity to undertake a complete state-of-the-art refurbishment of the branch. This includes the provision of additional customer interview rooms plus the repositioning of its customer counter which has created an extra customer service counter position.
There is now also increased accessibility for customers, making the branch more user-friendly for mothers with babies/young children and customers with disabilities.
During its closure, Santander customers were able to use the Santander branch on Shipquay Street.
John Feeney, Branch Manager, said: “We very much looking forward to seeing our customers walk through the doors again and wish to thank them for their patience. Our thanks also to the staff at Shipquay Street for supporting us and our customers during this time.”
