The contractor criticised for closing a path which served as a Hampstead school’s fire escape route with just three days notice has apologised.

Willmott Dixon, which is carrying out work on the Royal Free Charity’s new Pears Building in Rosslyn Hill, shut an alley so it could be used by lorries and trucks as an access road.

The contractor has accepted not enough notice was given to Hampstead Hill School and the construction working group (CWG) set up to scrutinise the project.

CWG member and Hampstead Town councillor Maria Higson (Con) had criticised the firm and the Royal Free Charity over the “complete lack of transparency”.

A spokesperson said: “We provided three days of notice before the closure of the footpath, which we accept is too short and apologise for the inconvenience.”

They added they hoped to be a “a good neighbour” and ran “social value projects” to help locals.
