www.disabledliving.co.ukThey are a charity. Try asking them by email whether they can give you the 0161 number.
I've just Googled and found 0161 834 2001 as being given for DL, but it's shown on the
contact page as being for "PromoCon" at the same address. Thus, maybe they are in the same office - although they do have a separate fax, so maybe not.
Another number I found is
0161 214 5959. This, along with 0161 839 1066 is listed on
BT Directory Enquiries.
Assist UK also reside at the Redbank House, so it may use one or more of those 0161 numbers.
