I hate to be a smartarse

but I can't resist it - I pay £0 for hangarage of my R44 - that is zero, zilch, nada, nothing.
Cornish cowshed within curtilage which came with house helps.
Conversion to hangar cost £4000, Helimover £2000, Pilot Controlled Lighting £700, Pre-loved Industrial Dehumidifier £250. Flying from home to work almost every day between March and October - priceless.
I have space for an R22 if anybody is interested and would charge considerably less that Xavier Dosh feels reasonable.
Only problem - it's in Cornwall!
Hangarage for my Mooney costs me £280 inc vat per month. I do the moving and valeting (suits you sir!

) whatever that is.
If you are looking in the London area why not try Redhill - they very kindly stuck my R44 in a hangar for 1 week in Nov 2004 whilst I flew out of LGW to the US and back. Cost £50 - and they even helped me with the moving/valeting - big empty hangar and really great guys

.
Every time I venture within the M25 my wallet gets liposucked.
Xavier Dosh mate, you ain't 'avin any of mine sunshine
