MP Norman Baker MP cut the ribbon to officially open the new look Chyngton Eastate post office on Wednesday.
He was joined by residents, postmaster Nik Patel and his wife, branch manager Aeri Patel.
Post Office services are provided at two combination counters in the refurbished store, where the Post Office terminal sits alongside the till.
The retail has also had a major refurbishment and it has become Walmer Convenience Store under the Premier store brand.
The store also offers longer opening hours.
Mr Patel, who has been postmaster for two-and-a-half years, said, “Customers really like the appearance of new-look Post Office and convenience store.
“It is light, bright and modern.
“They love the longer hours, The open-plan Post Office tills now make it far easier for staff and customers to have conversations and to be friendlier and helpful.
“Customers also now like the bargains available in the convenience store.”
Mr Baker said, “Longer opening hours at the weekend, early in the morning and in the evening will make it more convenient for customers.
“I am delighted to be here today to congratulate postmaster Nik Patel on his vital community role. The Post Office and the whole store look great.”
Chyngton Estate is open Monday – Saturday: 8am to 8pm; Sunday: 8am – 5pm. This is an extra 35 hours a week, including all day Sunday and Saturday afternoon. The branch will also open earlier and close later. This will give customers more choice when it is convenient to visit.
Martine Munby, Post Office Senior Stakeholder Manager, said, “We understand how important having a Post Office is to residents in this area of Seaford.
“I am confident this new modern Post Office will meet the needs of the local community and secure services for the future. This modernisation is part of a major investment programme, the largest in the history of the Post Office. It marks a commitment to no more branch closure programmes.”
Under the current Parliament the Government has committed £1.34bn for the Post Office network to make sure there is no programme of Post Office closures and to update branches.
