Since I haven't work with British customer for the past few years .( mainly because I was out of hotel furniture business during those few years. I am not aware about their new regulations. )

Below comments are based on my previous experience , Most of British commercial furniture customer would require furniture with fire-resistant certificates, usually there are :

British Standard BS7176

According to my experience with my customers,  BS7176 is available to guide the responsible person (who is often the owner of a commercial project like hotel building,restaurant or business offices etc ). 

Usually it can be tested by authorities like SGS or Intertek etc, 

There are three different types of test procedure:

• Smouldering cigarette test (BS EN 1021-1:2006)

• Match flame test (BS EN 1021-2: 2006)

• Smouldering and flaming ignition sources test (BS 5852: 2006)

It is recommended for customer from UK to check with your local authorities if they require paticular fire-resistant certificate for furniture materials. So that china hotel furniture manufacturer will ensure they provide furniture made from material with proper fire-resistant treatment.
