The coastal town of Lyme Regis saw the second-largest increase, with prices rising 52.6% over the 10-year period.
Typical property values climbed from £308,000 in 2015 to £470,000 in 2025.
Year-on-year, transactions fell by 30% from 2024 to 2025, contrary to expectations of a recovery.
George Abouzolof, senior mortgage adviser at Clifton Private Finance, said: “While Land Registry data highlights a significant rise in property values across many UK towns, the figures also reveal how uncertainty in 2025 caused noticeable hesitation among buyers and sellers.
“Our analysis shows a 37% decline in property sales between 2015 and 2025. Similarly, while many predicted a rebound in sales from 2024 to 2025, our findings tell a different story, with sales falling by 30% year-on-year, marking a sharp and unexpected dip.”
Although average property values across the towns analysed fell by 2% between 2024 and 2025, several locations recorded strong annual growth.
Beaumaris saw prices rise 12.12% year-on-year, from £260,000 in 2024 to £291,500 in 2025.
Wilmslow followed with an 11.64% increase, with prices climbing from £396,330 to £442,475 over the same period.
Over the full decade, Wilmslow recorded total growth of 48.36%.
Abouzolof added: “While the South West of England remains the most prominent region for property value surges, we’re now seeing encouraging signs of growth in towns across the North West and Wales.
“This shift highlights emerging opportunities for property investment in areas that may not have traditionally been seen as offering the best value or return, but are quickly proving otherwise.”
