The constituency covers the eastern half of the London Borough of Hounslow, containing ten wards thereof: Chiswick Homefields, Chiswick Riverside, Turnham Green, Brentford, Isleworth, Syon, Osterley & Spring Grove, Hounslow Central, Hounslow South, and Hounslow Heath.
The Hounslow side of the constituency is strong for Labour, in sharp contrast to neighbouring wards which fall in the Twickenham or Richmond Park constituencies and which return large Lib Dem majorities. It is in the east of the constituency, the three Chiswick wards in particular, that the Conservatives are strongest. Chiswick has a higher number of professionals and much desirable housing. The wards of Osterley & Spring Grove and Hounslow South are more marginal.
