In the FOI request, the Department for Work and Pensions (DWP) said that, as at February 2019 (which is the latest date for which data is available), there were 11,000 persons in receipt of Adult Dependency Increases (ADIs) to their state pensions.

The estimated cost of the ADIs paid with state pensions in 2019/20 is £33million.

A DWP spokesperson told Express.co.uk: "The ending of ADIs was part of a package of reforms introduced in 2010, which meant that overall more women received the full basic State Pension and more generous National Insurance credits for carers were introduced.

“After 6 April 2020, current ADI recipients may be eligible for a means tested benefit such as Universal Credit or Pension Credit.

"Those already in receipt of a means tested benefit should see no change to their income as the loss of the ADI will be offset by an increase in their means tested benefit.”

According to the DWP, since 2010, each year’s annual uprating notifications sent to people in the UK has included information about this change, and more recently these details have been included in uprating notifications sent to those living overseas.

The new and basic state pension will rise by 3.9 percent in April 2020, under the triple lock.
