The DWP has a plan to consolidate its job centres on one site. Brent Council is quoted in criticism in the story despite the fact that the Council followed a similar logic in relation to its own revenue and benefit department. When that body temporarily housed an office at Harlesden Job Centre, it found it much under used. The planned facility at Willesden Library was abandoned for a similar reason.
The argument is that as more and more people are active online for all sorts of reasons, they no longer need the (more expensive) face to face access.
If Brent Council really feels this logic does not hold, it would be better advised to offer some of its buildings to offer temporary "pop up" access.
