Hamble Valley.

Hamble Valley is a South East seat of small and mid-sized towns clustered around the lower reaches of its namesake river, with no single dominant centre. Locks Heath, the largest built-up area at roughly 35,750 people, accounts for about a third of the seat; Hedge End follows at some 23,281, and the remainder is spread across Whiteley, Netley, Bursledon and a scatter of villages and rural ground. The population of around 101,061 is older than the national norm at a median age of 43, overwhelmingly White at 95 per cent, and modestly graduate at a degree-educated third. Three district councils run local services across the constituency: Fareham, which holds six of its wards, Eastleigh with five, and Winchester with a single ward, so a seat that straddles three authorities is a defining administrative fact about the place.

That cross-council geography shows in the ward map. Across the twelve most recent contests, held in May 2026, the Conservatives and the Liberal Democrats each took six, the Conservatives stronger in the Fareham wards around Locks Heath, Park Gate and Sarisbury, the Liberal Democrats ahead in the Eastleigh wards around Hedge End and Botley. Turnouts clustered consistently around the high 2,000s to 3,000s, with little of the unevenness that flags a contest swinging hard one way. At Westminster the picture is narrower: in 2024, the first General Election fought on these 2023 boundaries, the Conservatives won on 36.4 per cent against the Liberal Democrats on 27.5, a margin of under ten points. The sitting member, Paul Holmes, has held the seat since the boundary change and shown no whipped dissent in the past 90 days.

On the figures available the seat reads as genuinely contested rather than settled, a sub-ten-point parliamentary margin sitting atop an evenly split local map. Recent local coverage has had a markedly administrative character, dominated less by partisan drama than by the mechanics of local-government reorganisation and the routine business of council elections. None of the recorded crime categories runs materially above the local average. The standing implication is of a seat in flux: a Conservative hold won on a little over a third of the vote, a Liberal Democrat challenge that already wins half the wards, and a council landscape itself in transition.
