Summary
The W1B market in September 2026
Sold prices in W1B are +1.0% over the twelve months to December 2025 on the house price index. Over five years it is +17.6%.
W1B has too few repeat sales for an index of its own, so the published series is the national one. Its turns are national, not local.
16 sales were registered in W1B in the twelve months to January 2026, −48% on the twelve months before, at a median of £2,450,000. Counts are from HM Land Registry directly; months from February 2026 are still filling and are left out of the total.
On the portals, asking prices moved +1.4% and asking rents +6.0% over twelve months. Asking leads sold by months and includes what never sells. The pipeline publishes these quarterly for this area because the monthly move is too noisy to resolve.
In April 2026, 2 homes came to market in W1B and 67% of listings were reduced. The median asking price was £3,775,000, £30,063 per square metre. New builds were 0% of listings.
5 agents listed a home for sale that month; the three busiest held 67% of listings.
14 homes were live for sale in W1B on 7 September 2026, at a median asking price of £1,412,500, with a median listing age of 152 days. The stock count is observed daily from 5 September 2026 and settles as the portal sweep completes.
5 residential lots went to auction in W1B over the last 5 quarters with results; in Q2 2026, 1 was offered and 0 sold. Guide and hammer averages are computed on different lots, so the table shows both with their counts rather than a difference.
382 homes in W1B hold an energy certificate. 22% are rated A or B and 19.9% D or worse. 66.8% heat with mains gas, 6% with a heat pump. Certificates are lodged on sale or let, so long-held and social housing are under-represented.
