Most other airfields that I know of charge £5 per T&G and £10-£15 per landing!
(for info, "most" for instance - Stapleford £5TG & £17LD; Elstree £5TG & £15LD; North Weald - Donation for both; Damyns Hall - always free; Thurrock £10LD; Fairoaks £18LD; Blackbushe £15LD; Oxford £16LD... Even Lydd is cheaper at £23LD & £8TG)
I agree with the rough summary of prices at those airfields, however I just think that, for the sort of establishment you seem to desire to continue to operate from - within the south-east, and at a reasonable distance from central London - you will have to pay similar rates to those you have been paying at Biggin for the privilege. it is just market forces. The airfields you list with low prices do not have all of the following:
hard runways are important due to wet weather, lights are important because some of us land at night, and IAPs are important because some of us fly approaches regularly...
Anyway, good luck with being able to continue at Biggin Hill.
