Minimum fare £36.00 and £2.20 per mile thereafter, Chauffeur prices.
The longer the distance the lower the price per mile becomes.
I do loads of long distance mainly wait & returns.
We caharge a premium for into Central London also because of the traffic.
For standard PH though I believe it is driven by the Metered fare, good job this does not apply in London though, no metered cars you see only Black cabs are HC
Average PH mileage here is min fare £6 and around £1.60 per mile.
That assumes of course the driver speaks English and knows where he is going, for the other lot they quote £1 per mile and get lost and charge a fortune accordingly, even though everything is supposed to be fixed.
