The Labour leader will highlight findings in a report, commissioned by the party, which found that elderly people in nearly two-thirds of areas surveyed in England are visited for no more than 15 minutes and that many care workers are not paid if they choose to extend a visit. Between 150, 000 and 220, 000 care workers receive less than the minimum wage often because they are not paid as they travel between appointments.
Miliband will say that the report by Labour's Lady Kingsmill shows short visits and the treatment of care workers has reduced the quality of care for millions of elderly, vulnerable and disabled people who need help preparing meals, bathing and taking medication to allow them to remain at home.
One of Kingsmill's central recommendations is for a new care charter to be developed by the Care Quality Commission (CQC) to raise standards. This would end time-limited visits and introduce an inspection regime.
The CQC would also get new powers to tackle the exploitation of care workers whose treatment has an impact on the people they care for. It would have a duty to refer cases where it believes minimum wage laws have been breached to HM Revenue & Customs.
Miliband said: "Denise Kingsmill … shows that the army of care workers, who carry out some of the most important work anyone can do looking after parents, grandparents and the most vulnerable in our society, are often exploited with real consequences for those they care for.
"I know that councils are under enormous pressure from reductions in central government funding But I am also determined that a Labour government will call time on clock-watch care. We will work with councils and care providers to end this practice."
Liz Kendall, the shadow social care minister, is releasing figures alongside the report which shows half of care providers inspected by HMRC have failed to pay the minimum wage. In response to a freedom of information request, HMRC reported "non-compliance" with minimum wage requirements in 101 out of 201 enquiries, while arrears of £1m have been identified.
Kendall said: "Care workers do an incredibly important job, looking after our loved ones when they are at their most vulnerable. Yet thousands are not even paid the minimum wage, let alone a living wage.
"The news that half of all providers inspected by HMRC have failed to pay the minimum wage is shocking. Over £1m is now owed to care workers...It is totally unacceptable that companies are failing to meet their legal duties."
Kingsmill said: "Care for elderly and disabled people is a major issue for the mid-21st century. We are likely to live longer and a large number of is will require care in our final years. Improving conditions for care workers and care recipients is a journey: we need to act now."
