Story summary

Properties worth more than £2 million in London have seen their values drop by an average of £284,583 since the beginning of this year due to concerns over Labour's upcoming mansion tax, according to new figures from property experts TwentyCi. Under the controversial plan announced last year by former Chancellor Rachel Reeves, homes valued at or above £2 million will face an additional annual tax bill ranging from £2,500 to £7,500 starting in April 2028. This has led to a significant decrease in demand for high-value properties; during the period from April to June 2026 alone, homes sold at discounts of up to £315,119 on average. Additionally, TwentyCi reports that houses above the mansion tax threshold are now taking an average of 86 days to sell compared to just 41 days for those below it. Chris Sykes, a property finance specialist, noted a noticeable drop in activity within the £2 million to £2.5 million price range as potential buyers reconsider their decisions.
