How do I get a VT 2400 over ten years old start switch repaired ?

i have been informed by the service center that my serial number is over 10 years old on my polio vaperet to 2400 & polio do not produce parts for this machine.
the problem with my machine is it will not switch the heating element on - the other switch to release the steam lights up ok. is there any local repair center to leeds that could repair my machine
