Cheers guys, thanks for the replies.
Unfortunately Kent is a bit far - We are in Northants!
I'm just kicking myself for not putting the website that I found the information on (about this company in Luton) in my Favorites.
I travel through Luton once a week and I've been told by a Vauxhall dealer here in Northants that thay supplied a van to another window cleaning company and they had it fitted out by this company in Luton. But they don't have any further details.
Apparantly the company is located near the B&Q depot near Dallow Road. I'll have to have a drive around. If anyone from Luton knows any more info, it would be a great help.
Thanks again.
Steve
