The Autumn Budget brought predictable housing and tax shifts, headlined by a 2028 levy on £2m+ homes that affects under 1% of properties but will shape behaviour for years. Landlords face tighter margins as taxes rise, while Attleborough’s market absorbs uncertainty. The measures add clarity rather than comfort as pressures build.

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.”

A new £2m-plus home surcharge is billed as progressive, but its impact falls mainly on London and the South East, where many owners now face an annual bill from 2028. Critics warn it punishes long-term residents, cools the prime market and deepens regional divides, even as households weigh downsizing. Many fear a new cliff edge at £2m too.

If you’re planning to sell in early 2026, now is the time to understand the timeline, the preparation and the steps that will help you move smoothly from listing to completion.
