The plans were revealed to Hammersmith MP Andy Slaughter , who said the move was “very concerning”, while long-term branch user and stand-up comedian Richard Herring said he was sad to learn the news from staff.
The Post Office announced on Wednesday (October 26) said the relocated branch within WHSmith - some 450 metres away - would offer the same range of services, and not result in job losses.
However, Mr Slaughter says the move is a further blow to Shepherd’s Bush following the announcements that Morrisons and HSBC were closing branches , and comes after he was assured the Post Office’s future was safe.
He said there has been too many post office closures in the surrounding area.
The MP said: “I’m very concerned about the announcement to relocate Shepherds Bush Post Office, especially as I was told three weeks ago that there were no plans to do this.
“The current branch is well-used and in a good location.
"The new site is not in the town centre and it is less accessible, making it more difficult for local people to use the services provided by the Post Office.”
And on his blog he wrote: “It follows on from main Post Office closures in Hammersmith and West Kensington, and "temporary" closures of the sub offices in St Ann’s Road and on the BBC Media Village site.
“This is the last Post Office in the area in a dedicated building.
"It is in an accessible town centre location, and in my experience is always busy.
“This would also be a further service gone from the Shepherd’s Bush Green area, as both Morrisons and HSBC have said that they are to close their local branches.”
He suggested the branch could remain close to its current location by taking over either of the sites being vacated by Morrisons and HSBC.
The Post Office is inviting customers and interested parties to give their comments on the proposed move in a six-week public consultation which runs until December 7.
Mr Herring said the branch had undergone a huge improvement under new management, and that the “brilliant and extremely busy staff” were concerned with the developments.
Staff are 'understandably nervous about it'
Writing on his blog he said: “I was sad to be informed today that the Post Office is planning to shut down this important main branch and move the store to inside WHSmiths in the Westfield.
“After all that this team has done for them they are going to shift them (and at least, for now,there are no job losses, though I wonder if that will come too) and they are understandable nervous about it.
“And it does seem a big shame to move this centrally located main post office to the back of a shop, which is much less conveniently located.
"Especially given how many of the smaller post offices have also gone.”
