Hi,
No detailed knowledge about the state of the runways, but think that the airfield is part of the Duke of Westminster's estate,Eaton Hall, (he owns a corporate jet which is based elsewhere).
I seem to remember mention that some aircraft were based there a few years back - a civvie owned Tucano springs to mind.
Looking at an aerial photo on multimap suggests one runway may be reasonable, with the other completely unuseable :
