This seat is one of three that lie in the borough of Hillingdon, situated on the north western edge of London.
The seat, which borders the South West Hertfordshire constituency, shares more characteristics with its neighbouring seat, than with other Greater London seats. The only real variation in this constituency is between the comfortable middle classes and more wealthy neighbourhoods and private estates especially in Eastcote, Ruislip and Northwood wards. There is some local authority housing - just over 11% - but unemployment is very low, at 1.3% and falling.
An issue of present contention here is the government’s plans to close down Harefield Hospital which lies in the seat. A campaign has been set up to block this- MATCH (Movement against the closure of Harefield Hospital).
