I started jumping at Headcorn after doing my AFF abroad, they were quite welcoming and quickly got my to my A licence as my AFF was uspa.
Has all the facilities to get jumping but a big criticism sadly is some of the staff attitude, rude and obnoxious. I get the impression I should be honoured to jump with them as opposed to being treated with respect as a paying customer. Majority of staff are friendly and helpful, its just a few bad apples that spoil it.
All that said, Headcorn isn't that bad, good equipment, manifest works well with a 10 min notice, canteen is ok but don't expect a gourmet meal! 2 planes (1 goes to 12k the other to 10k)Lots of air displays from aerodrome whilst your waiting. Good landing zone as well.
