I have what I consider to be a generic English accent, though not RP/BBC. I live in the middle of the country and so I have random features from different accents, so it's sort of hybrid in a way. As examples, I mostly (but sometimes switch!) use the short "a" sound (think jam) in words like grass and bath which is very much a northern feature. But then I also use the glottal stop and drop the t at the end of words like "what" and "not" which is a southern Estuary English London accent feature - think David Tennant's Doctor Who. People have a great deal of difficulty in placing what part of the country I'm from, which is amusing to me
