The care minister Norman Lamb has said it is "unrealistic" to think 15 minutes is enough time to provide adequate care to the elderly and disabled.
Data obtained from 63 local authorities in England by a care charity found that three-fifths now commission 15-minute visits, despite concerns that short visits "deprive" people of essential care.
Norman Lamb said there were too many examples of councils buying "rushed care visits": "It's unrealistic to think that 15 minutes is enough time to help people who are older or who have a disability to do everyday things like wash, dress and get out of bed.
"It's not fair on those who need support and it's not fair on care workers."
The minister insisted the Government needed to help provide "better care for the 300,000 people currently getting home care" and for those likely to need it in the future.
Health Minister Norman Lambhas told The Daily Telegraph it is not acceptable that there are no “clear standards of the training that must happen in a care home”.
He told the newspaper:
I would not want a loved one of mine - or indeed myself - to be cared for by someone who has no training.
Criminal prosecutions must follow in the "most outrageous" cases of abuse but reforms are needed to improve the quality of care more widely in nursing homes and in pensioners' own homes, he said.
The Liberal Democrat minister said the new regime must not create “a tick box” culture, adding: “But the bottom line is, I don’t want a loved one being looked after by someone who has really no idea what they are doing.”
