Q We received pension Credit briefly in February and did not have to pay council tax. Now we have been asked for £817 council tax.

My husband has a State Pension of £159.61 a week and Industrial Injuries Benefit of £24.76 a week. I have Incapacity Benefit of £74.15 a week.

We cannot understand why we have to pay all this money.

A If you are entitled to Guarantee Pension Credit, you are entitled to a full council tax rebate. Once you cease to receive Guarantee Pension Credit, you will only have a maximum council tax rebate if your income is less than £188.60 a week.

Otherwise, you must pay 20p a week for every £1 that your income is above £188.60.

With an income of £258.52 a week, you will have to pay council tax of about £727 a year.

Q I have been receiving Pension Credit of £30.68 a week in addition to my State Pension and Attendance Allowance.

Now that I need more care, I am going to share with my daughter and her husband who have moved into a bigger house.

However, I am told I will lose my Pension Credit. Can you clarify this?

A When you lived alone, your Pension Credit included the Severe Disability Premium (SDP). However, if you go to live in someone else's house, you will lose the SDP if you are no longer treated as living alone.

You can still be treated as living alone, even if you live under someone else's roof, if you have entirely separate living accommodation. If you lose the SDP, another person may claim Carer's Allowance of £45.70 a week for looking after you.

Q My State Pension is £51.89 a week and my partner's is £139. I have a private pension of £209.57 a month and he has Attendance Allowance. Our savings are just over £15,000. Can we claim anything?

A You should claim underlying entitlement to Carer's Allowance and reduce your council tax to £462 a year.
