Cornwall: the market in figures

Midway down the table, Cornwall holds 57th place nationally, with 12th place of 13 in the South West. At £274,570 it is 0.6% above the UK's £273,037 and 9.7% below the regional £304,139, so it lands almost on the national line.

The recent trend points down. Over twelve months the average fell 2.9%, while the South West stood at 0%. The high came earlier, in 2022, at £294,537, and today's price is below it. The low was in 2016, at £202,236. Even so, the period as a whole shows growth of 35.8%, or £72,334. The strongest year was 2022 with 14.7%, followed by 2021 with 10.5%. Falls arrived in 2024, at 4.8%, and now at 2.9%, with 2023 sitting at 0%.

Detached houses top the list at £419,340, followed by semi-detached homes at £275,595, then terraced at £227,474; flats are lowest at £144,637. Between the lowest and highest types lies £274,703, or 189.9%. First-time buyers average £226,508, 17.5% lower than the all-buyer figure, and owe £0 in Stamp Duty Land Tax. The usual bill comes to £3,729 (1.4%), while an additional property owes £17,457. HM Land Registry takes £150.

The neighbours give a mixed picture. City of Plymouth (£223,229) is 18.7% lower and rose 3.2% over twelve months. West Devon (£286,921) is 4.5% higher, Exeter (£289,403) 5.4% higher, Teignbridge (£298,159) 8.6% higher and South Hams (£360,616) 31.3% higher. South Hams gained 0.8%, while West Devon, Exeter and Teignbridge slipped by 1.5%, 0.7% and 0.5%. Cornwall's fall of 2.9% is therefore the sharpest of the group.

Sales reached 8,004 during the year ending May 2026, a large count that makes the fall of 2.9% hard to put down to a few unusual deals. Cornwall therefore combines a price level close to the UK average with a falling trend and a busy market, a mix that the neighbour table above shows is not shared by Plymouth.
