I searched for quite some time without success and I am Pretty good at finding things.
Contact Hoover using this link:

I could not even come up with the part number for the door. I did find the following:
1. Door Seal
2. Door Glass
3. Door Handle
4. Door Hinges
No luck on finding the complete door assembly.
Another alternative... if the Yorkshire area has an appliance recycling venter you may be able to find one there or in the classified ads "for parts only" But then your faced with disposing of the "junk."
I recommend you contact Hoover using the number or Lonk above and see what they can do for you.
I wish I could have done more for you but the whole door assembly just does not seem to be readily available.
Thanks for choosing FixYa,
