The National Pensioners Convention said the Government and local authorities need to do more to improve standards of care.
Dot Gibson, general secretary of the pensioner organisation, said:
Around 80% of home care is now provided by the private sector, yet a significant number of them are failing to treat older people with the dignity and respect they deserve.
Local authorities have a responsibility to start commissioning services on the grounds of quality - rather than for the lowest price.
Contracts should only be awarded to those who can guarantee that staff are properly trained and qualified to do the job - and the idea that services can be provided in blocks of 15 minutes at a time has got to stop.
