Dorset: the market in figures

Dorset sits above its own region. Its £328,589 average runs 8% above the South West (£304,139) and 20.3% above the UK (£273,037), which gives it 4th place among the 13 covered South West areas and 36th of the 135 nationally. The latest twelve-month change is a fall of 0.4%, while the South West overall was flat at 0%. Its 4th place within the South West means only the areas ranked above it cost more. The peak was reached in 2022. The series starts at £256,086 in 2016, and gains of 6.3% in 2017, 9.1% in 2021, with 14.3% following in 2022 took it to £344,688. Since then the line has been soft: down 3.3% in 2023, down 1.2% in 2024, up 0.2% in 2025 and down 0.4% in 2026. Even so the full period shows a rise of 28.3%, worth £72,503, and 2016 remains the lowest year.

The type table starts at £169,474 for flats and climbs through £267,978 (terraced) and £333,127 (semi-detached) to £519,998 for detached homes. The first-time buyer average is £257,241, 21.7% below the figure for everyone. SDLT is £6,429 for a home mover here (2%), £1,429 on a first purchase, and £22,859 on an additional property, with £150 payable to HM Land Registry.
