Minus 32. That is the number driving conversations in estate agents' offices across Kingston upon Thames this week, and it is worse than almost every economist predicted. The RICS September 2026 survey London house prices Kingston upon Thames data landed on 9 October, and within a day Reuters had flagged it as a clear signal that the brief summer recovery in the housing market has stalled.
For anyone buying, selling, or letting property near the Thames in Kingston, this is not an abstract national statistic. It shapes how quickly a riverside flat sells, how hard a buyer can push on price, and whether a landlord's listing attracts three viewings or none.
Key Takeaways
- The RICS house price balance fell sharply to -32 in September 2026, down from a five-month high of -28 in August, a bigger drop than economists polled by Reuters had forecast.
- London recorded the most negative price balance of any UK region, while Scotland and Northern Ireland bucked the trend with rising prices.
- New buyer enquiries weakened for the first time since March 2026, even though new seller listings rose for the first time since mid-2025.
- Surveyors expect further price falls over the next three months, with prices stabilising over a 12-month horizon.
- Renewed interest rate expectations, with markets pricing a Bank Rate rise at the 5 November meeting, are the main headwind cited by RICS.
What the RICS September 2026 Survey Actually Found
The RICS UK Residential Market Survey is one of the most closely watched barometers of the property market because it asks chartered surveyors and estate agents directly what they are seeing on the ground, rather than relying solely on completed sales data. The headline figure is the "net balance", a measure of the difference between surveyors reporting rising prices and those reporting falling prices.
In September 2026, that balance dropped to -32, a sharp reversal from August's five-month high of -28. According to Reuters' reporting on 10 October, this decline was larger than City economists had expected, which matters because it suggests the slowdown is not simply a seasonal blip.
A few other details stood out in the survey:
- Downward pressure on prices increased for the first time in four months, ending a brief period of relative stability.
- New listings rose for the first time since mid-2025, meaning more property is coming onto the market even as demand softens.
- New buyer enquiries weakened for the first time since March 2026, a sign that the appetite to view and offer on property has cooled.
- Surveyors collectively expect prices to fall further over the next three months, before settling into a more stable pattern over a 12-month horizon.
Tarrant Parsons, RICS head of market research, summed up the shift plainly: "A renewed rise in interest rate expectations has created a fresh headwind for the housing market."
Why London, and by Extension Kingston, Is Feeling It Most
Regionally, the picture is uneven. London posted the most negative price balance of any part of the UK in September, while Scotland and Northern Ireland reported rising prices. This north-south, or more accurately capital-versus-regions, divide has been building for some time, but the September figures sharpen it.
For Kingston upon Thames, sitting within Greater London's south-west commuter belt, this regional context is directly relevant. Kingston's market has traditionally been underpinned by:
- Family houses in sought-after pockets near good schools, which tend to hold value better in slow markets but are not immune to weaker buyer enquiry numbers.
- Riverside and town centre flats, a segment more exposed to affordability pressure and mortgage rate sentiment, given it often appeals to first-time buyers and buy-to-let investors.
- Commuter demand, driven by fast rail links into central London, which supports underlying interest even when national sentiment is soft.
None of the RICS data is Kingston-specific, and it would be misleading to claim otherwise. But a London-wide price balance this negative, combined with rising listings and softer enquiries, points to a local market where sellers need to be more realistic and buyers have more room to negotiate than they did even two months ago.

Interest Rates: The Real Story Behind the Numbers
The single biggest factor behind September's weaker survey results is interest rate expectations. Bank Rate currently stands at 3.75%, but financial markets are now pricing in a rise at the Bank of England's 5 November 2026 meeting. That shift, which has happened relatively quickly, has fed straight through into mortgage pricing and buyer confidence.
This matters because the housing market since 2024 has been unusually sensitive to even small rate moves. A rise, or even the strong expectation of one, raises the cost of borrowing, squeezes affordability calculations, and makes buyers hesitate before committing to an offer.
Supporting evidence from other sources points in the same direction:
| Data source | Metric | Latest figure |
|---|---|---|
| RICS | September price balance | -32 (from -28 in August) |
| Lloyds | Average house price, September | £298,441 (unchanged on month) |
| Nationwide | Monthly change | -0.2% |
| Nationwide | Annual growth | +0.8% |
| ONS | Private rental growth, August | +3.8% annually |
| Bank of England / Garrington | Mortgage approvals, August | 16% lower year-on-year |
Lloyds' figure of unchanged prices at £298,441 suggests a market that is flat rather than collapsing. Nationwide's small monthly dip alongside modest annual growth tells a similar story: subdued, not dramatic, but clearly losing momentum. Mortgage approvals falling 16% year-on-year, as reported by Garrington using Bank of England data, reinforces that fewer people are getting to the point of agreeing a mortgage in the first place.
The Lettings Side: Rising Rents, Thinner Supply
The RICS survey also captured a parallel story in the rental market. Tenant demand is rising while landlord instructions, the number of new properties coming onto the rental market, are falling. This imbalance helps explain why the ONS recorded private rents up 3.8% annually in August.
For Kingston landlords, this combination of rising demand and shrinking supply is, on paper, good news for rental income. However, it also reflects a wider trend of landlords exiting the market or holding back from relisting, often due to higher mortgage costs, tax changes, or uncertainty about future regulation. Anyone considering selling a rental property in Kingston should weigh this against the softer sales market described above.
What This Means for Kingston Buyers
If you are searching for a home in Kingston upon Thames right now, the September data gives you some genuine leverage.
- More choice is appearing. Rising new listings mean fewer bidding wars and more room to compare properties before committing.
- Enquiries have softened, so sellers who were testing high asking prices over the summer may now be more open to negotiation.
- Expect prices to drift lower over the next three months, according to surveyor expectations, which supports a patient, unhurried approach to offers.
- Mortgage costs could rise again if the Bank of England moves on 5 November, so get a rate held or locked in sooner rather than later if you are close to exchanging.
What This Means for Kingston Sellers
Sellers face a tougher environment than the one suggested by August's brief uptick.
- Price realistically from day one. Overpricing in a market with rising stock levels and weaker enquiries risks a stale listing, which almost always sells for less eventually.
- Expect more negotiation. Buyers have more choice and more caution, so be prepared for offers below asking price, particularly on flats.
- Highlight what's resilient. Family houses in good school catchments and well-presented riverside properties still attract interest; lean into these strengths in marketing.
- Review pricing against recent comparable sales, not against what similar properties achieved earlier in the year.
Why an Independent Valuation and RICS Survey Matter More Than Ever
In a market this uncertain, guesswork is expensive. A professional, independent valuation, carried out by a RICS-qualified chartered surveyor, gives buyers and sellers a clear, evidence-based figure rather than relying on estate agent estimates designed to win instructions.
Equally important is commissioning a proper building survey before exchange. A RICS Level 2 Homebuyer Report is suitable for conventional homes in reasonable condition, covering structural issues, damp, and overall condition in plain language. A RICS Level 3 Building Survey is more thorough and better suited to older, larger, or period properties, including many of the characterful houses found around Kingston's riverside and conservation areas.
With prices under pressure and lenders applying closer scrutiny to valuations, a proper survey is not an optional extra. It protects buyers from overpaying for hidden defects and gives sellers a stronger negotiating position if they commission one proactively.
FAQ: RICS September 2026 Survey and the Kingston Market
What is the RICS house price balance and why did it fall to -32?
It is a net measure of surveyors reporting rising versus falling prices. A reading of -32 means significantly more surveyors reported falling prices than rising ones in September, a sharper fall than August's -28 and worse than economists expected.
Does this mean Kingston upon Thames house prices are definitely falling?
The RICS survey is national and regional, not Kingston-specific. London as a region recorded the most negative balance in the UK, which suggests softer conditions locally, but individual Kingston property prices depend on type, condition, and location.
Why are interest rate expectations affecting the market now?
Markets are pricing in a Bank Rate rise at the Bank of England's 5 November 2026 meeting, up from the current 3.75%. Higher expected borrowing costs typically reduce buyer affordability and confidence, which is exactly what RICS reported.
Is it a good time to sell a flat or house in Kingston?
It depends on your circumstances. Rising listings and softer buyer enquiries mean more competition for sellers, so realistic pricing and a strong, well-presented listing matter more than usual.
Should landlords sell now given rising rents?
Rental demand is strong and rents are rising, which may favour holding rental property for income. Selling into a softer sales market with lower mortgage approval volumes could mean a lower sale price, so landlords should weigh income potential against capital value carefully.
Why should I commission a RICS survey if I'm buying in Kingston?
A RICS Level 2 or Level 3 survey identifies structural or condition issues before you commit financially, and an independent valuation ensures you are not overpaying in a market where price direction is uncertain.
Conclusion
The RICS September 2026 survey London house prices Kingston upon Thames data confirms what many local agents and surveyors have sensed for weeks: the brief summer stabilisation has given way to renewed caution, driven largely by interest rate expectations ahead of the 5 November Bank of England decision. London's price balance is the weakest in the UK, buyer enquiries have softened, and surveyors expect further falls before conditions settle over the coming year.
For Kingston upon Thames buyers, sellers, and landlords, the practical response is the same regardless of which way the market tips next: price property based on solid evidence, negotiate with the knowledge that stock levels are rising, and never skip an independent valuation or RICS Level 2 or Level 3 survey before committing to a transaction. Speak to a local chartered surveyor before you list, offer, or exchange, so your next move in Kingston's market is based on facts rather than headlines.
