Does anyone know of anywhere in Scotland where we can get our seatbelts replaced or shortened?
After weeks of research, wrapping and unwrapping the seatbelt from the bar under the seat we have come to the conclusion that the only safe option open to us is to get the belts replaced.

Our son is 5 and in a high backed booster held in by the adult belt. I was under the impression that buckle crunch wasn't an issue for this stage of seat but after several long phone calls to Britax have been told that it is still a problem.
I sent photos of our Britax evolva 123 seat in place and have had it confirmed by Britax that the buckle position is unacceptable. They have also told me that it is not safe to wrap the belt around the seat bar as this could put stress on the belt at the wrong angle or cause fraying.
I have found companies in London that can shorten/replace the belts but haven't been able to find any up here in Scotland.
Does anyone know of anywhere?
