Hi,
I don't know of any specific podcasts or radio shows although I'm sure, somewhere there's going to be something along these sorts of lines. Perhaps join up at moneysavingexpert.com where there's everything and more 'finance' related in one website. Perhaps there's some podcasts etc there too, or hopefully, in the forums, someone will know more about where to find them etc.
Another good online resource is 'the fool.co.uk' which again has lots of information etc to read up on and a lively forum with many many subjects/focus areas.
These are good reputable websites to begin researching the various finance aspects in the UK and of course, from there, there's plenty of other good resources too.
Cheers, DtM! West London & Slough UK!
