Depends if the bumper needs replacing or not. If it is just removal,
repainting and replacement the ?300 ought to be enough. However, if a new
bumper is needed, it could be rather more. Is it a black cab type taxi or a
saloon car? If it is a standard car, what is it? I can look at our panel
supplier for a bumper price.

Hi Rocky
depending on what make of car/taxi you hit, I would say  ?100-00 was about
right to repair and paint most coded bumpers, considering we are in the
north west,,, furthe south can be a bit more expensive,
My mate has just had a quote for a small dent and a deep scratch on a
Chrysler PT cruiser n/s/ rear door , done by some kid on a bike ,
Metalic blue , so the rear wing and n/s/ front door will need to be partly
painted and laquered to lose the colour , if you know what I meen,
total cost = ?100-00,   thats ?50-00 paint and materials and ?50-00 labour
