There is undoubtedly some discount for basing your aircraft at Redhill, but the website suggests £8/night for a single as a starting point, so probably around £2500/year. As for hangarage, there isn't a huge amount of space, and pricing depends largely upon the size (wingspan) of the aircraft. Around £5000/year sounds about right for most typical singles.
