I am confused - the live chat corner says you posted some info for me - does this mean you are researching the answer & will reply to me later as I am worried because your system did not want to accept my email address initially - in other words please update me & advise if I can do other things on my computer.
Have you complained to the Council at all please?
Complain to the Council as they appear to be in breach of the Equality Act 2010.
This states that they must take account of your disability and make reasonable adjustments.
You should also complain to the Equality Commission. They deal with discrimination where it has taken place and can prosecute for you.
Their website is: http://www.equalityhumanrights.com/
But try the Council first and then Equalities Commissiob
Can I clarify anything for you about this today please?
Surely this is an issue with the tradesmen who undertook the work & have not considered disabled access.
