Amber Valley MP Nigel Mills officially opened a revamped post office in Heanor last Friday.
The newly modernised office now has four serving positions - a mixture of two screened counter positions and two open plan.
Customers are also set to benefit from opening hours being extended on Saturday afternoon until 5.30pm.
Mr Mills MP cut the ribbon at an event hosted by the owner Joanne Taylor on Friday morning which was attended by staff, customers and friends and a large cartoon hound.
Later on the same day the MP also experienced what’s involved in delivering the post when he joined Ripley postman Geoff Clarke on his delivery round.
Mr Mills said: “Accompanying Geoff as he posted mail in the constituency meant I was able to see for myself the various challenges he and others come across in their daily rounds.
“Our postmen and women provide an incredibly important service for the city’s residents – and for me as local MP, in making sure that crucial constituency correspondence gets where it needs to go.”
The post office was closed for refurbishment works from March 12 to March 30 and re-opened on Thursday March 21 at 9am.
Post Office regional network manager for Central England, Adrian Wales said of the revamped post office in Heanor: “This modernisation is part of a three-year investment programme, the largest in the history of the Post Office, that will see around 6000 branches - about half the Post Office network - converting to new-style branches.
“This investment makes a commitment to no more branch closure programmes.”
