Edgware is a suburban town in northern Greater London, mostly in the London Borough of Barnet but with some parts falling in the London Borough of Harrow and in the London Borough of Brent. Edgware is centred 9.5 miles (15.3 km) north-northwest of Charing Cross and has its own commercial centre. Edgware has a generally suburban character, typical of the rural-urban fringe. It was an ancient parish in the county of Middlesex directly east of the ancient Watling Street, and gives its name to the present day Edgware Road that runs from central London towards the town. The community benefits from some elevated woodland on a high ridge marking the Hertfordshire border of gravel and sand.

Greater London is the administrative area of London, England, which is coterminous with the London region. It contains 33 local government districts: the 32 London boroughs, which form a ceremonial county also called Greater London, and the City of London. The Greater London Authority is responsible for strategic local government across the region, and regular local government is the responsibility of the borough councils and the City of London Corporation. Greater London is bordered by the ceremonial counties of Hertfordshire to the north, Essex to the north-east, Kent to the south-east, Surrey to the south, and Berkshire and Buckinghamshire to the west.
