Hi nattrass. Welcome to the site.
I'm in Reading too. On the ChipsAway web-site they mention a partnership with Halfords so I phoned the Oxford Road branch as I've picked up some damage. (Bad parker hit rear right corner, motorbike scrapped front left corner weaving between traffic, car in-front threw up metal rod from road which bounced up the bonnet of my car ) Halfords said the partnership never happened and gave me the number of the local franchise guy - 0118 9664729. I've not tried them yet as I can't afford it and I'm waiting to see how the claim goes with the motorbike's insurance.
