Just one in four homes priced above £2m sold in Q3 2026, according to research from property intelligence firm TwentyCi.

TwentyCi also discovered that fewer than half of flats were likely to find a buyer this year.

The findings, published in TwentyCi’s Property & Homemover Report – Q3 2026, highlight significant differences in the likelihood and speed of property sales across the UK housing market.

The report found that 25% of £2m-plus homes reaching an outcome in Q3 sold, compared with 53.1% of properties priced below £2m.

High-value homes also took more than twice as long to sell, with a median time to sale of 86 days, against 41 days for properties below the £2m threshold.

Flats are also experiencing mounting challenges. Nationally, just 41.2% were likely to sell in 2026, down from 44.2% in 2025 and 54.2% in 2022.

The outlook was particularly challenging in London, where the likelihood of a sale stood at just 27.2% for flats in inner London and 30.7% in outer London.

Colin Bradshaw, chief executive of TwentyCi, said: “The housing market cannot be understood through headline transaction volumes or average property prices alone. Our latest research highlights how sharply the likelihood and speed of a sale can vary, with flats facing increasing challenges and properties at the top end of the market taking considerably longer to find buyers.

“For mortgage lenders, this reinforces the importance of understanding the dynamics of the individual property and its local market when assessing security. A valuation provides an essential benchmark, but insight into current supply, demand and selling times can add another valuable dimension to understanding the risks associated with a property.”

The report also found that £2m-plus homes that sold achieved 90.5% of their initial asking price, compared with 96.3% for properties priced below £2m.

However, TwentyCi cautioned that the figure for high-value properties was based on just 27 completions during the quarter and should be viewed as an early indication rather than a definitive market-wide trend.

The findings form part of TwentyCi’s quarterly Property & Homemover Report, which analyses the UK residential property market using factual property change data covering 99.6% of sale and rental property transactions.

Almost one in 10 homes currently listed for sale in London would have fallen within the scope of the government’s mansion tax had the threshold been reduced from £2m to £1.5m, Yopa research revealed this week.
