If you have more than �16,000 in capital, you will not get any Housing Benefit, unless you are getting the guarantee part of Pension Credit. If you have capital of over �6,000, you will be assumed to have some income from that capital.
You will not be able to get any Council Tax Benefit if you have capital (savings or property) worth over �16,000. If you have capital over �6,000, you will be assumed to have some income from that capital, and this will reduce the amount of Council Tax Benefit you can get.
