Cormac, Cornwall Council's cleaning company, has been awarded a contract by Cornwall Partnership NHS Foundation Trust to carry out maintenance works at 28 sites across the county.
From this month, it will provide "a full suite of facility, property and maintenance management services, adding cleaning to the work already undertaken".
Cormac will retain the previous contractor's skilled workforce of 23 and, as with its existing team, will pay all staff the living wage. Transferring staff will also undertake a comprehensive learning and development programme.
The contract will see Cormac providing services across 28 trust health sites and offices in Cornwall.
Works cover all foundation trust freehold properties in Cornwall and the contract will run for three years, with the option to extend it by a further two years. Cormac said this would bring "long- term security for both staff and the business".
