Lloyd George's "nationalisation of club medicine and local insurance in 1912 was the progenitor of the NHS in 1948". The panel doctors were subject to “terms of service” which were later lifted directly into the NHS GP contract.

The scheme was administered by local insurance committees covering counties and conurbations which held a panel of doctors prepared to work under the scheme. National contracting of general medical (general practitioner) services can be traced to the National Insurance Act 1911 which introduced a pool (similar to today's "global sum") to pay GPs on a capitation system building on the traditions of the friendly society. Normal working hours of 8 am to 6.30 pm Monday to Friday are specified in the contract. Alternative Provider Medical Services contracts, unlike the other contracts, can be awarded to anyone, not just GPs, don't specify standard essential services, and are time limited. They are designed to encourage practices to offer services over and above the standard contract. The other forms of contract are the Personal Medical Services or Alternative Provider Medical Services contracts. The contract has sub-sections and not all are compulsory. In 2013 60% of practices had a GMS contract as their principle contract. Today, the GMS contract is a UK-wide arrangement with minor differences negotiated by each of the four UK health departments. The NHS specifies what GPs, as independent contractors, are expected to do and provides funding for this work through arrangements known as the General Medical Services Contract. General medical services ( GMS) is the range of healthcare that is provided by general practitioners (GPs or family doctors) as part of the National Health Service in the United Kingdom.
