A lifeline extended to the Shepherd's Bush Job Centre will last at least until the next election.
The Ealing Gazette obtained the assurance from Tony McNulty, the Employment minister following a recently announced moratorium on 25 branches across the country.
The impetus came from continued fears surrounding rising unemployment and recession.
The threat of closure had loomed over the Uxbridge Road site and scores of other sites since February as the Government looked to make savings.
On a visit to the centre today Mr McNulty said: "I don't think we'll be looking at it for a couple of years. This is not a decision to reverse in the next three-to-six-months, I want to make it very clear that the review process has been suspended.
"I genuinely believe that of the 25 that were earmarked for closure there is a more compelling case to keep this one open, especially because you have got to give it time to see Westfield bedded in."
Mr McNulty refused to be drawn on the level of unemployment that it was bracing for amid the economic downturn, but economists have predicted three million at the height of the downturn.
The minister said a £1.8 billion investment in employment services as announced in the Government's pre-budget report, would provide "robust and flexible support and guidance."
Joe Reilly, a Job Centre advisor and PSU representative, said: "Whether we have a Labour or a Tory Government, we are certain Job Centre will be line for closures again and we will challenge any attempt with vigour.
"With the government wanting lone parents and disabled people to be looking for work now, the need for them to stay open is even more imperative."
Shepherd's Bush MP Andy Slaughter, who Mr McNulty said was constantly in his ear about the merits of the Shepherd's Bush centre, said: "Even before the downturn it was a daft idea to close a facility that is sited literally between a major new employer - Westfield - and areas of high and long-term unemployment."
