Don't forget that there are various BENEFITS available, which have no stigma attached to them. In fact, the government wants you to have them if you are eligible.
I used to be an expert when I worked for the CAB, but I'm not any more, nor up to date, so I will only talk in generalities.
The first is PENSION CREDIT. This is for pensioners on a low income, and with savings below a certain threshold.
The details are here:
Pension Credit is extra money for pensioners to bring your weekly income up to a minimum amount - what you'll get, apply, eligibility.
www.gov.uk
As well as giving you about £14 per week extra (for a single person, more for a couple), it has lots of valuable fringe benefits such as free dental care, subsidised specs, and a free TV licence if over 75.
If you meet the criteria, you get it, "simples".
A bit more complicated are the benefits for disabilities, namely DLA (Disability Living Allowance) if below pension age, and AA (Attendance Allowance) if above pension age.
These have long complicated forms, with lots of questions that can be misinterpreted when you fill it in. And whether or not you get it is judged by a non-medical person on the basis of your answers.
I once helped someone to appeal whose DLA claim was turned down. It was obvious she had great difficulty walking. When I went through the form she'd filled in, one of the questions was "Do you have any difficulty going up and down stairs at home" to which she'd replied NO.
When I asked her about this, she explained that she lived in a bungalow and therefore had no difficulty going up and down stairs at home!
So I suggest getting help from the CAB, Age Concern, or various other disability organisations for these benefits. It is much easier to get the benefit in the first instance then to appeal it afterwards. And don't hold anything back in your answers out of pride, for example., say it like it is.
