London’s 32 boroughs and the City of London each handle filming permissions independently. When you know where you want to shoot, you’ll apply to the local council’s film office.
So, for example, Westminster City Council notes that certain shoots with small crews (five people or less, handheld only) do not require an application if filming doesn’t block access or equipment on the pavement. This particular borough even offers customers a free 20-minute consultation service for help and advice before you apply, so that you can be sure if you do or don’t need permission.
The City of London, on the other hand, always requires permission for any filming on streets or parks it controls, and issues a Notice of No Objection via its Filmapp system.
In every borough, the process begins by explaining your plans – location, dates, crew size, equipment – so they can advise on permits, risk assessments, insurance and any other requirements. Most councils will have an online form where you upload all of these details, and sometimes additionals like a detailed scale drawing of the activity area or the description of your activity, including the infrastructure used and any activities involving children or VIPs, etc.
In other words, you share as many specific details as possible so that the BFS can determine whether the filming can safely take place in their borough.
