London house prices are under pressure while mortgage costs stay high. See what a 3.75% Bank Rate means for buyers, renters and the buy-or-wait decision.
London’s housing market is giving buyers a strange message in 2026: home prices are falling, rents are still rising, and mortgage rates have become more expensive again. That means a lower asking price does not automatically mean a cheaper monthly housing cost.
Quick answer: London house prices were down 3.3% year over year in July 2026, while the average London rent reached £2,332 a month in August. The Bank of England kept Bank Rate at 3.75% on September 17, but three of nine policymakers wanted a rise to 4%, and fixed mortgage rates have moved higher. For buyers, the decision is less about whether prices are “cheap” and more about whether the mortgage, deposit and time horizon make sense together.
Updated September 21: Rightmove says only 42% of homes for sale in London are currently finding a buyer, while the average two-year fixed mortgage rate has risen to about 5.29%. That combination gives buyers more negotiating leverage on price, but financing remains the bigger affordability constraint. Rightmove House Price Index, September 2026.
What is happening to London house prices in 2026?
The latest official UK House Price Index data from the Office for National Statistics show that London was the weakest UK region for annual house-price growth. Average London prices fell 3.3% in the 12 months to July 2026. It was the eleventh consecutive month of annual price declines in the capital, and the average London home stood at about £569,000 — roughly £19,000 below the recent July 2025 peak.
That headline hides a highly uneven city. Some boroughs are falling much faster than the London average. Camden, for example, was down 10.1% year over year in July, while Westminster was down 20.7%. Other areas were much more stable, and some outer-London boroughs still posted small gains. The point: “London house prices” is not one market.

What is the Bank of England interest rate now?
The Bank of England held Bank Rate at 3.75% at its September meeting. The vote was 6–3, with three Monetary Policy Committee members preferring an increase to 4%.
The Bank also said UK CPI inflation had risen to 3.1% in August and warned that inflation risks were tilted to the upside. That matters to homebuyers because mortgage pricing is influenced not just by today’s Bank Rate but also by expectations for future rates and by money-market conditions.
The Bank specifically noted that quoted two-year fixed mortgage rates were around 95 basis points higher than before the recent energy shock.

Why are London mortgage rates still expensive?
Mortgage rates can rise even when the Bank of England does not change Bank Rate. Lenders price fixed mortgages partly from swap rates — financial-market expectations for future interest rates — as well as funding costs, competition and borrower risk.
As of September 19, Rightmove reported average two-year fixed rates for homebuyers at approximately:
- 4.97% at 60% loan-to-value
- 5.30% at 75% loan-to-value
- 5.35% at 85% loan-to-value
- 5.55% at 90% loan-to-value
- 5.98% at 95% loan-to-value
Those averages are not guaranteed offers, and actual pricing depends on income, deposit, credit profile, fees and lender criteria. But they show why falling house prices have not automatically translated into easier affordability.

What does a London mortgage look like in pounds per month?
Take the latest official average London house price of £569,000. With a 25% deposit, the mortgage would be £426,750. At an illustrative 5.30% repayment rate over 25 years, the monthly payment is about £2,570.
If a comparable rate were 4.37% — roughly 0.93 percentage points lower — the same loan would cost about £2,341 a month. That is a difference of roughly £229 every month, or about £2,750 a year, before fees, insurance, maintenance or service charges.
With only a 10% deposit, the loan would be £512,100. At an illustrative 5.55%, the repayment is about £3,160 a month over 25 years.
These are examples, not mortgage quotes. They show why the interest rate can matter as much as the property price.
Are London rents falling too?
No. The latest ONS data show the average London private rent at £2,332 per month in August 2026, up 3.5% from a year earlier. Across the UK, average rent was £1,400.
That creates the central tension in the London housing market: purchase prices are falling, but renting is not becoming cheaper.
Using the simplified example above, an average London rent of £2,332 is below the roughly £2,570 monthly mortgage payment on a £569,000 home with a 25% deposit at 5.30%. But that comparison is incomplete. A homeowner builds equity, while a renter keeps the deposit available. Owners also face transaction costs, repairs, insurance, possible leasehold service charges and the risk of price changes.
Is it cheaper to rent or buy in London in 2026?
There is no single answer because the most important variables are personal: deposit size, mortgage rate, expected length of stay, rent on a comparable property and the cost of owning that specific home.
A useful way to frame the decision is:
- Buying becomes more defensible when you expect to stay for many years, have a strong emergency fund after the deposit, can comfortably afford the payment even if other costs rise, and are buying a property you would still be willing to own if prices fall further.
- Waiting or renting becomes more defensible when buying would consume nearly all your liquid savings, the monthly payment is much higher than rent, your job or location may change, or you are relying on near-term house-price appreciation to make the numbers work.
The wrong question is simply: “Are London prices down?” The better question is: “What is the total cost of owning this specific property for the number of years I expect to keep it?”
Should first-time buyers buy now or wait?
First-time buyers face two separate problems: the price of the home and the price of financing it.
Lower property prices help the deposit calculation. But a higher mortgage rate can erase much of that benefit in the monthly payment. A buyer who waits for rates to fall also takes the risk that prices, competition or rents move against them before that happens.
Rather than trying to predict the exact bottom in prices or rates, first-time buyers can test three scenarios:
- Buy now: current property price and current mortgage rate.
- Rates rise: same property with a mortgage rate 0.5–1.0 percentage point higher.
- Wait: continue paying rent while keeping the deposit invested or in cash and reassess later.
If only one of those scenarios is financially survivable, the decision may be too fragile.
What happens if mortgage rates rise again?
Using the same £426,750 mortgage over 25 years, a payment around £2,570 at 5.30% would rise to roughly £2,763 if the rate were 6.05%. That is almost £200 more each month.
That is why affordability should be stress-tested rather than calculated only at today’s advertised rate.
What could make London housing cheaper from here?
Three developments could improve affordability:
- mortgage rates falling;
- home prices falling further;
- household incomes rising faster than housing costs.
But those forces do not always move together. A weak economy can push house prices down while also making jobs less secure. Higher inflation can push wages up while also keeping interest rates higher.
The MNS decision framework: buy, wait or keep renting?
Buy when the home fits a long-term plan, the payment leaves room for saving, and the deposit does not destroy your emergency buffer.
Wait when affordability depends on optimistic assumptions about future rates, future salary growth or future house-price gains.
Keep renting when flexibility has real value and the ownership premium is large — but treat rent as part of a financial plan rather than a reason to stop saving.
If you are considering a major purchase, use the MNS Buy or Wait tool to structure the decision, or explore Smart Spending for more decision frameworks.
Bottom line
London homes are getting cheaper on official transaction data, but borrowing has become more expensive and rents are still rising. That combination makes 2026 less a “buyers’ market” than a decision-quality market.
The best opportunity may not be the lowest headline property price. It may be the property where price, deposit, mortgage rate and time horizon finally line up.
