On a day-to-day basis a wonderful source of information is the charity Disabled Living Foundation or DLF for short. They have several great websites when it comes to finding a piece of kit or equipment that you may need, from handrails to hoists.
Other good sources of information include several trade shows which take place most years, such as Naidex and the Mobility Roadshow.
Make a space in your diary, as these are excellent places to track down the items you might need, to find information, and to talk to the experts. Best of all, in these hard-pressed times, entry is free-of-charge, but don't tell them that I told you :-)
