Seems the link doesn't work, unless is sold. I've seen Profession 2200S for £360, otherwise would buy it from there.
do you have the link? I think I found and the item from Robert Dyas is Professional, not Platinum: https://www.robertdyas.co.uk/char-broil-professional-2200s-2-burner-gas-grill-stainless-steel-w The difference is in the material quality.
Really hope the OP didn't buy at that price, currently available at Robert Dyas for £360!
Thanks for sharing. Being in your place I think I would do the same.
