London prime real estate market fluctuations

The London prime property market has experienced significant shifts in both the rental and sales sectors. In the first half of 2026, luxury house rents in Prime Central London surged by approximately 67%, reaching an average of £4,177 per week. This spike was driven by a 44% year-on-year contraction in rental volumes for properties exceeding £1,000 a week, which Beauchamp Estates attributed to landlords exiting the market due to regulatory and taxation concerns.

By the third quarter of 2025, the sales market also showed signs of contraction, with prime property listings declining by 3.4%. This decline was linked to market uncertainty regarding potential changes to the Mansion Tax, despite the proposal to lower the tax threshold being dropped. While some areas like Fitzrovia and Marylebone saw sharp decreases in listings, others like Kensington and Chelsea saw increases. Experts noted a slowdown in transactions caused by “buyer paralysis” as potential purchasers hesitated due to economic concerns and Stamp Duty costs.
