Quick Summary

A new report from property data firm TwentyCi claims that homes valued at more than £2 million are less than half as likely to reach exchange stage compared to cheaper properties, suggesting the impending mansion tax is already impacting sales. The analysis covers June to September and shows a significant disparity: 53.1% of homes under £2 million reached this stage, while only 25% of those over £2 million did so. This finding adds to concerns about London's prime property market, which has been struggling due to increased mortgage costs and other taxes.

Story summary

As of October 16, 2026, homes worth more than £2 million are now less than half as likely to sell compared to cheaper properties, according to an analysis by property data firm TwentyCi. This finding raises concerns about the impact of the Government's upcoming mansion tax, which was announced in last year’s Budget and is set to come into force in April 2028. The levy will apply to properties valued at £2 million or more. According to TwentyCi's analysis covering June to September 2026, while 53.1% of homes listed below £2 million reached the exchange stage, only 25% of those above the threshold did so. Over this period, 966 homes worth over £2 million were sold, but another 2,898 either failed to find a buyer or were withdrawn from the market. This trend adds to existing pressures on London's prime property sector due to higher mortgage costs and increased stamp duty.
