Rightmove Reveals Britain’s 2026 Seaside Property Hotspots

Britain’s coastal property market is actively defying the national real estate cooldown, with targeted regional pockets outpacing the wider UK index.

According to new market data from Rightmove, which tracked over 100 coastal towns, average asking prices across the country fell slightly by 0.3% year-on-year. However, specific seaside locations are experiencing significant double-digit capital appreciation, driven by a resilient wave of buyer demand. The data highlights a major regional shift, with North West England and Wales entirely dominating the growth charts.

The North West and Wales lead the charge

The undisputed winner of Rightmove’s summer league table is Bootle in Merseyside, where average asking prices surged by 11% over the last 12 months. Interestingly, despite this rapid capital growth, Bootle remains one of the most accessible coastal locations in the country, with average house prices sitting at a modest £141,680—well below the current UK national average of £378,304. Just ten minutes up the coast, Crosby locked in the second-place spot with a 9% annual increase, lifting its average property value to £330,900.

Meanwhile, Wales secured five of the top ten positions on the leaderboard. The glamour pocket of Penarth in South Glamorgan saw prices climb 8% to an average of £433,081. This makes Penarth the highest-value location on the fast-growth list and the only hotspot to trend completely above the baseline national average.

While affordable growth locations are stealing the headlines, the ultra-prime coastal market remains firmly anchored along the southern coastline. Every single one of the top ten most expensive seaside towns in Great Britain is located exclusively in either the South West or South East. The glamorous enclave of Sandbanks in Poole, Dorset, comfortably retains its crown as Britain's most expensive seaside hotspot. Average entry prices here hover at £1,119,945.

It is closely followed by its neighbouring enclave, Canford Cliffs, where premium waterfront real estate commands an average price tag of £1,045,533.

For property portfolios, the overarching takeaway from the data is clear: while luxury hubs hold their multi-million-pound baselines, the fastest-moving capital growth is currently being generated by liquid investors targeting high-yield, undervalued coastal developments further north.
