Care Circle Ltd and Slemish Homes Ltd, part of the Care Circle Group in Northern Ireland, have gone into administration.
The two businesses own the Braefield in Connor, Slemish in Ballymena and Kingsway in Dunmurry care homes. They also operate the Fairfields home in Cookstown, employing 310 permanent and agency staff, The Irish News reports.
Appointed administrator Deloitte said the homes would continue to operate as normal and no job losses were planned.
Peter Allen, of Deloitte, said: “All necessary steps have been taken to ensure the existing standard of care remains in place at the homes.
“We are operating closely with the regulator and the trusts, and we will be meeting residents and their families to explain the purpose of the administration and to provide comfort that there will be no material difference in how the homes operate.”
Mr Allen said a buyer was being sought for the homes, which would be sold as a going concern.
Care Circle Group provides residential, nursing and dementia care at homes in five locations in Northern Ireland.
Four Seasons announced the closure of seven loss-making homes in Northern Ireland last year (see Four Seasons shutters care homes in Northern Ireland).
