London’s property market is not moving in one direction.
The latest official figures show that the average London property price fell by 2.2% in the year to August 2026, reaching approximately £554,000. Yet the headline figure hides a significant divide: average flat prices fell by 5%, while average house prices increased over the same period.
For buyers, sellers and investors, that difference matters. A realistic strategy for a London flat may now look very different from the right approach for a family house—even when the properties are located in the same borough.
London prices remain below their 2025 peak
According to the Office for National Statistics and UK House Price Index, London’s average price was £554,430 in August 2026. This was around £15,000 below the recent peak of £569,000 recorded in July 2025, although it was £8,000 higher than the recent low of £546,000 in March 2026.
The annual fall also eased from 3.2% in July to 2.2% in August. On a monthly, non-seasonally adjusted basis, London prices rose by 0.7% between July and August.
These figures suggest a market that has softened, but not one that is simply collapsing month after month. Prices are moving unevenly, and the type of property has become especially important.
Why the flat market deserves separate attention
Flats account for approximately half of property sales in London, compared with around one-fifth across Great Britain. That means weakness in the flat market has a much larger effect on London’s overall figures than it would elsewhere.
The official data shows average London flat prices falling by 5% over the year to August, while houses rose. Buyers considering flats are often assessing more than the purchase price: lease length, service charges, reserve funds, planned major works, ground-rent provisions and building-safety documentation can all affect affordability and confidence.
These issues do not make flats poor investments. In the right building, location and price range, they can offer an accessible entry point into London ownership and attractive rental demand. However, buyers are increasingly likely to compare the total cost of ownership rather than focusing only on the asking price.
Mortgage demand has also cooled
Bank of England figures published on 29 October show that net mortgage approvals for house purchases fell to 53,400 in September, down from 54,800 in August and below the previous six-month average of approximately 58,800.
The effective interest rate on newly drawn mortgages increased slightly to 4.63%, from 4.60% in August. Even small movements can affect monthly payments when London purchase prices and loan balances are high.
Lower approval numbers do not mean that buyers have disappeared. They indicate a more restricted pool of financed purchasers, making sensible pricing and mortgage-ready properties increasingly important.
Transactions remain subdued
HMRC’s latest data recorded an estimated 94,800 seasonally adjusted UK residential transactions in September 2026. This was 4% lower than September 2025 and marginally below August 2026.
It is worth remembering that completed-transaction statistics typically reflect offers agreed two to four months earlier. They are useful for confirming the broader direction of the market, but they do not show today’s buyer response in real time.
For individual properties, current viewing levels, competing listings and recent comparable sales remain essential.
What this means for flat sellers
The biggest risk for a flat seller is relying on an old valuation or comparing the property with a sale agreed during a stronger market.
A flat launched above current evidence may lose its most valuable period of online exposure. Buyers who see similar properties reduced several weeks later may wait rather than make an offer.
Before marketing, sellers should prepare the leasehold information that buyers are likely to request. Confirming the remaining lease term, current service charge, planned works, reserve-fund position and management arrangements can reduce uncertainty and make a well-priced flat easier to progress.
Where the building has strong management, a long lease, sensible costs or useful features such as parking, outdoor space or direct garden access, those advantages should be made clear from the start.
What this means for house sellers
The relative strength of London houses is encouraging, particularly where family supply is limited. However, it does not mean every house has increased in value.
Condition, road position, school catchment, parking, extension potential and local demand can create large differences between apparently similar homes. Sellers should use recent evidence from the immediate area and adjust for size and condition rather than applying London-wide growth to their property.
A correctly priced family house can still attract serious demand, but buyers remain conscious of mortgage costs and refurbishment budgets.
An opportunity for buyers and investors
For buyers, softer flat prices may create opportunities that were unavailable a year ago. There may be greater negotiating room where a property has been listed for some time, needs modernisation or has a motivated seller.
That opportunity should be assessed carefully. A reduced purchase price can be outweighed by a short lease, high service charges or major works. Buyers should review the legal pack, management information and building condition before treating a discount as genuine value.
Investors should calculate returns using realistic rent, void, management, finance and maintenance assumptions. The strongest investment is not necessarily the property with the largest headline reduction; it is the one where the total cost, rental demand and long-term resale position work together.
A market for evidence, not assumptions
The latest figures underline one central point: there is no single “London property market.” Flats and houses are behaving differently, and results vary substantially by borough, street, condition and tenure.
