[3] The seat is a mixture of very suburban London and urban district centres with many differing heights and types of homes.

The seat is affluent nearest the Thames and Osterley Park, yet it has a few tall tower blocks and other council housing set back from it in parts of Isleworth and Brentford.

Locally, 21st century development includes a large proportion of shared ownership and housing authority homes.

[4] About three wards make up Hounslow in the west, and two for Brentford in the centre, which, excluding its expensive Quay and North Quarter parts, have an above-average rank in the Index of Multiple Deprivation; many of these homes are affordable for workers on lower incomes, and are generally strong for the Labour Party.

Chiswick's large public sector economic component, and relatively young profile for a wealthy area sees a three-way or broader split in its general election votes.

The districts have tube or rail services to the east and west of London (to Heathrow Airport, Ealing and/or Weybridge), which are major centres of employment.

In 2015, Labour gained the seat, despite the Conservatives winning a majority nationally, thus ending its streak as a bellwether constituency.
