With plans announced to raise the council tax surcharge on higher-value homes, this snapshot looks at how many £2m-plus properties have actually sold across the UK this year. The data shows a highly concentrated market, dominated by London, and reveals just how small this sector is nationally despite the noise around a “mansion tax.”

An impressive individual 4-bedroom detached family home, situated in a non estate position on a plot of approx. a quarter of an acre plot and ideal for the centre of town, with a super south-facing rear garden, generous parking, a double garage and great potential to create the home of your dreams.

UK home sales agreed in 2025 tell a story of steady progress rather than drama. Many regions are seeing uplift thanks to realistic pricing and strong demand, while others are adjusting to affordability and expectations. The market is functioning, confident, and increasingly shaped by local conditions.

This map highlights the average size of homes sold across the UK since 2020, measured in square feet from completed sales. What stands out is how little the averages vary between regions, despite very different housing types. Northern Ireland is the clear exception, with noticeably larger homes on average.
