Yes, it's 0344 5532321. To help anyone else in the future, if you go to the Fujifilm UK website and click on Support, at the bottom right hand side you will see a panel Contact Us, that gives both their telephone number and email address.
After this post and my earlier one regarding my X-H1 I think I should say that I have no connection with Fujifilm except that of a very satisfied customer.
There is one negative which to me is a big one. They have not implemented the one thing I have asked every Fuji rep that I ever met for and posted on various forums. Why have they never provided a 5 x 4 ratio crop in the viewfinder, it's the most pleasing ratio for portraits and the standard size of event photography prints, which is why Nikon have always provided it in their professional cameras.
