Ambition 24hours was launched in 1996 as a temporary staffing agency to meet for the first time the need for a 24-hour staffing service in the nursing sector. Following rapid growth, over the next decade the company expanded the service to cover locum doctors, allied health professionals, carers, social workers and teachers & lecturers, and we established a national network of UK branch offices.

In 2004, the A24 Group expanded into South Africa, opening back-office facilities for the UK and SA markets. We also launched an £11 million ($17.25 million), three year investment plan in South Africa, based at 130,000 sq ft (12,000 m²) freehold premises acquired in Cape Town. We also initialised locum and nursing agency services in South Africa: 2004 marked the launch of domiciliary home care services, to provide private nursing and care giver directly to people at home for post-operative, geriatric, paediatric and other care.

In 2006, the company made its first major acquisition: that of South African agency NSSA (Nursing Services of South Africa), the largest provider of temporary nursing personnel in the country, supplying over 3,000 staff each month. A second office opened at 50 on Long Street, Cape Town.

In 2009, Nursing Services of the UK and Locum Services of the UK, the UK divisions of The Nursing Services of South Africa which operates through its UK branch NS Health Staffing, was launched.

Today the A24 Group is a multi-million dollar medical staff recruitment and management organisation operating with multiple brands in the United Kingdom and South Africa. The A24 Group has interviewers based nationally throughout the two countries and employs over 300 office staff across the world, with 27,500 personnel on its books - locum doctors, nurses, allied health professionals, care givers, teachers and social workers for major institutional service providers in two continents.

Arabella Health Staffing Ltd - a wholly-owned subsidiary of the A24 Group – acquired BNA, The British Nursing Association, and its associated nursing agency brands Grosvenor Nursing and Mayfair Nurses. Pinnacle Staffing Group Plc, the owner of BNA, accepted an offer for a consideration in cash of £2,750,000.
