Stretton can still be used with the landowners permission although you dont land on the old runway, its a 400m length of taxi way running along side the old runway. I landed there sometime last year but my passenger knew the land owner. Cant be much more helpfull than that im afraid.
There is also a strip next to the M6 motorway that is only a couple of miles away from Warrington. It looks to be 700m+ but dont know anything more about it.
