Field Fisher Waterhouse (FFW) has won out against 47 other law firms to become sole legal adviser to the General Social Care Council (GSCC), the regulator of the social care workforce.
FFW has secured a three-year contract with the GSCC, which could be extended by a further two years.
It is understood that a total of 48 firms applied for the role, with just four short-listed to take part in a beauty parade.
The GSCC was established in 2001, under the Care Standards Act 2000, and has responsibility for social care workers across the public, private and voluntary sectors. FFW assisted with the register of the 1.2m people working in social care and advised on the new regulatory framework for social care.
The legal team, led by Matthew Lohn, a former doctor who is now head of public and regulatory law at FFW, will act on professional regulation, employment and equality, property and service contracts, data protection, freedom of information, intellectual property and technology, among other areas.
