How can ATC tell you the pilot that the runway that you intend to land on is not long enough? ATC (the controllers) are not crunching the numbers to determine what length that you need or don't need to land or takeoff.
Now if there is a maximum weight limit established for a particular runway then ATC can deny a landing or takeoff clearance for your particular aircraft, but in the example that you gave, NO, unless the rules in the UK are vastly different than the USA.
