I’m NOT an expert but just trying to help.
I would say to get a regulator at a camping store and any other parts you might need to make the hook up ( new hose, clamps.. )
Use a regulator that closely matches the specs on the grill as far as pressure and Flow rate.
Make sure it matches the tank you plan on using!
If all else fails you could go to a Weber dealer in U.K. and just get a replacement regulator / hose set.. but this might cost more than at the camping shop.
If that fails.. just get a Master Touch and enjoy!
