A link for one popular type, Kiwi SDR is as follows:-
This should present you with a map of the world, zoom into the UK and then you can select a map point and go to a receiver. Once on a users Kiwi site simply use the control box to enter a frequency of your choosing and enjoy a listen

All the best,
