@almorton Vertigo were the only riggers I worked with in England and they were EXCELLENT! Can you come to the aid of @WCLJT22 ?
Toodleoo!

Not really my area, I'm afraid. Could be worth asking again on a UK based forum suxh as Blue Room - there are UK based theatre, circus and other live event riggers and designers on there for sure who will probably have an opinion. Blue Room.
Have not heard of them or worked with them, but my days of exciting international sorties are long over. Strictly domestic now.
However, looking into their accreditations and overall industry involvement in standards, I can't imagine you're looking at a bunch of neophytes by any stretch. @WCLJT22, have you spoken with them by phone yet? I'm sure they'd be more than willing to answer your questions and that will give you a better feel about hiring them. What's the nature and scale of your production?
