The Hemel Hempstead Constituency covers not only the whole of the town of Hemel Hempstead, but also the villages of Kings Langley to the south and Markyate, Flamstead, Potten End and the Gaddesdens to the north.
Hemel Hempstead is a thriving "new" town, so designated after World War II. It has excellent transport connections being on both the M1 and M25 and also on the main rail line serving London (Euston) with the Midlands, North West and Scotland.
The town is centred on Marlowes - the main shopping area - and the High Street in the Old Town. The residential area of the town is made up of neighbourhoods; five of which date from the New Town in the 1950s with others having been built later. The town also includes pre-New Town residential areas - Boxmoor, Apsley, Leverstock Green and Nash Mills.
The industrial area - Maylands - is at the edge of the town and includes the Buncefield Oil Terminal.
Some of the National Trust woodland at Ashridge also falls within the constituency.
