The CAA are the regulator for this: see Articles 94
Below is a copy and paste from the CAA website;
The CAA regularly receives queries regarding who may impose restrictions on unmanned aircraft use and the land from which they are piloted. The CAA can only provide information on its own regulations and permissions process and not those imposed by other bodies.
As set out in CAP 722, a CAA permission only addresses the flight safety aspects of the flight operation and does not constitute permission to disregard the legitimate interests of other statutory bodies such as the Police and Emergency Services, Highways England, Data Commission, Transport for London or local authorities. It may also be the case that more than one body has an interest in a proposed flight.
The CAA cannot provide advice on what is, or is not, a legitimate interest or whether restrictions or fees are being lawfully imposed by other authorities. However, any authority or regulatory body should be able to identify the specific laws, regulations or bye-laws that empower it to regulate the use of UAS, or more usually, the land from which they are operated, much as the CAA has set out the regulations that it applies, above. We therefore recommend that if you are unsure of whether a restriction imposed by a body legitimately applies to your flight, you request that information from the relevant authority or regulatory body.
UAS operators and remote pilots are also reminded that ANO Article 241 provides that a person must not recklessly or negligently cause or permit an aircraft to endanger any person or property.
I'm sure that the Laindon strip operator's concerns will be respected. As a CAA permission is required for out of sight commercial drone operations any potential conflicts will need to be addressed
