Soldato
I work for big national sub contractor and we don't bother with london either anymore. It's not even congestion charge but the often lack of parking at the sites and then traffic is so bad the operatives hate going there as they spending hours traveling to site and not actually working.Yep, I know a few tradesman who now just don't offer their services in London anymore. It's not worth it as they get plenty of work elsewhere. The result is you'll find it harder to get work done inside London at a sensible price.
