I would like to know if not having the funds would be looked on by the authorities as mitigating circumstances.
Also should I write back to this man (he is a barrister according to his profile) and what do I say to him.
Well that depends. If you are large chain like Hilton you would expect to have reasonable adjustments
If you are single 10 room b&b then you would not be expected to.
You only need to do what is reasonable.
You should write back and say it is reasonable to have an adapted bath.
You are a small hotel and this is reasonable
Does that clarify?
