Income from savings
[ch 4: page 35]The amount of Universal Credit you receive may also be affected by the amount of savings or capital you (and your partner) have. As well as cash savings and money in the bank or building society, it also includes assets like Individual Savings Accounts (ISAs), Premium Bonds and property if you do not live there. It does not include your pension pot if you have not started to draw it down.
If you have less than £6,000 your savings are ignored in the calculation, and if you have more than £16,000 you will not be entitled to any Universal Credit. For savings of between £6,000 and £16,000, the government ignores the first £6,000 and assumes that you get £4.35 for every £250 or part of £250 that you own above £6,000. This is irrespective of the interest you actually earn.
