From 1974 to 1996 the NHS in England was administered by regional health authorities. The regions closely followed the areas of the previous regional hospital boards established in 1947, but in many cases they were renamed.
Each Region was subdivided into area and district health authorities, whose disposition as at 1991 is listed below.
In 1996 the regional health authorities were reorganised as NHS health authorities.
- Northern and Yorkshire – Cleveland, north Cumbria, Durham, Humberside, Northumberland, North Yorkshire, Tyne and Wear and West Yorkshire
- Trent – most of Derbyshire, Leicestershire, Lincolnshire, Nottinghamshire, South Yorkshire
- Anglia and Oxford – Bedfordshire, Berkshire, Buckinghamshire, Cambridgeshire, Norfolk, Northamptonshire, Oxfordshire, Suffolk
- North Thames – Essex, Hertfordshire, North London
- South Thames (South East Thames & South West Thames) – East Sussex, Kent, Surrey, West Sussex, South London
- South and West (Wessex and South Western) – Avon, Cornwall, Devon, Dorset, Gloucestershire, Hampshire, Isle of Wight, Isles of Scilly, Somerset, Wiltshire
- West Midlands – Hereford and Worcester, Shropshire, Staffordshire, Warwickshire, West Midlands
