Mayfair Property Market: House Prices, Sold Data & Development Finance, Q3 2026 Review

Mayfair: Westminster super-prime market with lateral flat amalgamations and heritage refurbishment at the top end of UK values.

The Mayfair property market recorded 2,539 residential sales in the 12 months to 30 June 2026, with a median sale price of £800,000. This places Mayfair £320k above the Greater London county median of £480,000, and £515k above the approximate UK median of £285,000.

Prices in Mayfair have recorded a notable decline, a year-on-year change of -12.6%. Within Greater London, Mayfair ranks 5th by price out of 51 principal towns, and 28th by transaction volume.

On a quarterly view, Mayfair median prices moved from £820,000 in Q1 2025 to £750,000 in Q2 2026, a change of -8.5% over 5 quarters.

Mayfair shares a HM Land Registry reporting district with neighbouring towns, and the source data does not distinguish Mayfair-specific sales from the wider district. The figures above reflect the whole shared district rather than Mayfair alone.

City of Westminster, the local planning authority covering Mayfair, approved 24 residential planning applications and refused 5 in Q3 2026 (1 July to 30 September 2026), with 43 still awaiting a decision. That is an approval rate of 83%. Planning figures come from local planning authority records compiled by Landstack, retrieved on 3 October 2026. Councils and Landstack can take several days to publish decisions, so decisions made in the final days of Q3 2026 may not all be included yet.

Schemes approved in Q3 2026, together with those still awaiting a decision, propose around 173 homes, an estimated £147.3m of development value at local sale prices. Treat the unit total as an upper bound, since an outline permission and its reserved-matters application both count.

City of Westminster covers more than one town in Greater London, so these figures are authority-wide rather than specific to Mayfair alone.

Property prices in Mayfair vary significantly by type. The table below compares Mayfair prices with Greater London county averages and UK national figures.

Semi-detached homes in Mayfair command £4.49m, while flat properties are most accessible at £705,000. The £3.8m spread between the most and least expensive types indicates a diverse market with opportunities across the development spectrum.

HM Land Registry has so far registered 41 new-build sales in Mayfair for the past 12 months, 1.6% of registered transactions. New-build sales are typically registered 6 to 18 months after completion, so this understates current delivery and is not a completions figure.

New-build and existing sales in Mayfair differ too much in property mix to quote a like-for-like new-build premium: the gap between their median prices mostly reflects what is being built (for example, a small number of high-value schemes) rather than what a comparable new home commands.

Across the wider Greater London market, 1,006 new-build sales have registered so far. See our Greater London property market report for the full county picture.

For developers considering Mayfair, the local market data translates directly into finance structuring. With a median value of £800,000 and detached homes at £3.05m, lenders can assess scheme viability with confidence.

A typical development finance facility for a scheme in Mayfair with a GDV of £3.05m would attract senior debt of approximately £1.98m at 65% LTGDV. Mezzanine finance can stretch total borrowing to 85-90% of costs, while bridging loans enable rapid site acquisitions completing in as little as 5 working days.

While prices have softened 12.6% year-on-year, experienced developers can still generate strong returns in Mayfair by targeting well-located sites with clear demand drivers.
