I got this emai today from the C of L
"I write regarding the contractors that completed the fencing at the rear of your property this week. We were contacted by residents in Old Fox Close asking us to investigate a white van that was accessing the strip of land to the rear of these properties.
This strip of land is owned by the City of London as a public open space and is part of Coulsdon Common; therefore driving on it is in breach of our byelaws. It is your responsibility as the person who appoints the contractor to make sure they are compliant with our regulations and also to seek our approval, via a licence, for any such work that impacts on our land.
We visited the site on Tuesday afternoon (2nd August) and all rubble and associated rubbish has been removed with the area left clean and tidy, so we would not need to issue a licence as the works have now finished.
If you have any further work done in the future that needs vehicle access to the rear of the property, please contact us before any work begins."
