To answer your question the conditions, pay, roster, lifestyle etc...vary a great deal depending on the company you work for.
Primarily looking for a UK Base and a DEC if possible.
LEA, TAG uk, International Jet Club, Twinjet, Manhattan Jet Charter, Bookajet, 247 Jet, AV8, Hangar 8, GAMA, Titan, to name a few, all have bases in the UK.
Some companies will operate a 2 week on 2 week off roster, some a 28 on 28 off. You could be required to 'airline out' to the aircraft and 'airline back', not neccessarily having a base and not getting home for that period.
My advice would be to fire out a few cv's, try and get some interviews and see what they offer.
Good luck
