Can I claim disability benefit if I have substantial personal savings?

P.S. Anyone who wants to rant is quite welcome but I've worked all my life and never claimed a penny. Anyway, it's a hypothetical question.

if it's disability living allowance then yes you can

Karen is wrong!!!! - yes you may claim Disability Living Allowance as a benefit which is NOT means tested. Furthermore, as you indicate in your question, since you have 'worked' for many years then you should also consider making a claim for Incapacity Benefit too. This is also NOT means tested, but is based on your National Insurance contribution record. If you have 52 x the lower earnings limit National Insurance (paid) contributions in the two full tax years prior to the year of claim (which is a calendar year) then you ARE entitled to Incapacity Benefit now. You will need the assistance and support of your GP as your will need a MED4 certificate to 'prove' your incapacity for work.

Look on the Citizens Advice website (as below) to see the conditions of entitlement to disability benefits.

Should that not be sufficient information, go into your local CAB with details of your income and savings and they will calculate your entitlement, provided you have medical evidence of the disability, and of the bad effects it has on your everyday life.

I don't think you will be eligble, if you have savings over 拢7K.
