To be honest V1GO, I'd take your Cozy somewhere other than Biggin Hill.
The service at Biggin Hill is excellent providing you have at least 2 jet engines.
To be perfectly honest, the staff at the Regional Airports like Biggin Hill, Southend, Manston etc really hate to have things like COZY's, VEZE's etc etc operate from the airport, light aircraft like these cause far too much trouble, especially when the flimsy nose wheels fail, (which let's face it is very often) causing the quality traffic ie. BAe146's, B727's etc etc to go around and hold off until the runway is cleared and inspected (if it's prangs on the main RWY).
I'd recommend you use Fairoaks or somewhere like that who speicalise in VFR light aircraft stuff.
