I've had the same when listening to LBC News. They'll play an ID into the break, but the end will be cut off by a localised ad being inserted. Not long after noticing it, I switched to listening via RadioFeeds instead because it would subtly wind me up every time!

It's the same with some podcasts, even those that aren't from a big UK producer. I think they're done by aCast, there's a distinctive 2 note jingle before and after the breaks. I remember hearing adverts for a University near me on the American podcast Skeptoid. The clever thing is it seems to do it even if it is downloaded, the ad is inserted into the file on the fly

Global use it a lot for podcasts in Global Player and via third party apps. I was listening to one at work and got ads for TfL despite not being in London as the company Internet connection is there. Rewound the podcast and listened via 4G and advert for a local car showroom. It's all very clever stuff
