"Coastal properties may be attractive for rental yields and lifestyle appeal, but with extreme weather events expected to intensify, long-term sustainability must be a key consideration"
- Cliff Ward - Pikl

Demand for UK coastal properties continues to grow. As such, investors are weighing not only potential returns but also the rising risks posed by climate change. And as property prices remain high and affordability is squeezed, understanding the balance between investment viability and long-term resilience is more crucial than ever.

To help, Insurance experts at Pikl have analysed publicly available property market data to identify the UK’s top 10 coastal investment hotspots. Their assessment considers key factors such as Price-to-Income (PTI) ratios and flood risk levels, offering a comprehensive view of where investors can find the best opportunities while mitigating potential climate-related challenges. The findings also highlight how PTI ratios have evolved in recent years, reflecting broader trends in the property market.
