Because of the limited range of the drone, I believe it should only be necessary for you to contact your LOCAL air traffic control, and then only if you are operating within 5 miles of the restricted air space.

I am currently towards the end of qualifying and am just trying to complete the OE stage.
My examiner, who is operating as my observer, is requesting the telephone details of my local ATC at Manchester, Liverpool, Blackpool civil airports and Warton, a local military airport operated by BAe.
I am finding it difficult to obtain these telephone numbers. It's ok to find the airport general numbers but I thought that in the event of a real emergency access to direct ATC control at these would be more useful.
The same would be true for other pilots throughout the UK, hence the query.
