Twenty-two. That is the net balance of surveyors across the UK who told RICS that buyer enquiries fell in September rather than rose, the sharpest reading since March and a clear sign that the autumn market has lost momentum. For anyone buying, selling or holding a leasehold flat in W11, W2 or W10, the RICS September 2026 survey London weaker Notting Hill October 2026 story matters because it describes exactly the conditions now facing prime central London: more stock coming to market, fewer buyers chasing it, and prices under renewed pressure.
This article, written on 14 October 2026, sets out what the RICS data actually says, why London is underperforming the rest of the UK, and what it means practically for anyone negotiating on a period stucco house or a converted flat near Holland Park, Kensington or Ladbroke Grove this month.
Key Takeaways
- National buyer enquiries fell to a net balance of -22% in September 2026, the first weakening since March, according to the RICS UK Residential Market Survey published 8 October 2026.
- New instructions to sell turned positive (+6%) for the first time since mid-2025, meaning more stock is reaching the market just as demand softens.
- House prices nationally fell further (-32% net balance), with London notably weaker than the UK average; Lloyds data shows London prices down 1.5% year-on-year to September while the North West rose 3.1%.
- RICS's Tarrant Parsons says a renewed rise in interest rate expectations has created "a fresh headwind", relevant with Bank Rate at 3.75%, mortgage rates at a three-year high, and the Autumn Budget due on 28 October 2026.
- For Notting Hill sellers, more competition and cautious buyers increase the risk of down-valuations and post-survey price-chipping, making pre-sale condition checks more valuable than ever.
What the RICS September 2026 Survey Actually Shows
RICS publishes a monthly net balance survey of chartered surveyors and agents across the UK. A net balance is simply the percentage of respondents reporting a rise in an indicator (such as enquiries or prices) minus the percentage reporting a fall. It is not a measure of the size of the change, a net balance of -32% means far more surveyors saw prices falling than rising, not that prices fell by 32%.
The key national figures from the September 2026 survey, published 8 October 2026, were:
| Indicator | September 2026 | Previous month | Direction |
|---|---|---|---|
| New buyer enquiries | -22% | -18% | Weaker |
| New instructions to sell | +6% | 0% | First positive since mid-2025 |
| Agreed sales | -18% | -16% | Weaker |
| House prices (net balance) | -32% | -28% | Weaker |
| Three-month sales expectations | -6% | , | Negative |
| Three-month price expectations | -24% | , | Negative |
| Twelve-month price expectations | 0% | , | Flat |
| Tenant demand (lettings) | +23% | , | Positive |
| Three-month rent expectations | +37% | , | Strongly positive |
Tarrant Parsons, RICS head of market research and analysis, attributed the shift to interest rate pressure, saying "a renewed rise in interest rate expectations has created a fresh headwind." That headwind is consistent with the macro backdrop: Bank of England base rate sits at 3.75%, mortgage rates are at a three-year high, and markets are watching closely ahead of the Autumn Budget on 28 October 2026.
Why London Is the Weak Spot in the RICS September 2026 Survey
The RICS data is explicit that London underperformed the national average on prices in September. That regional divergence is echoed in the Lloyds house price index, also published 8 October 2026, which shows London prices down 1.5% in the year to September 2026, while the North West posted growth of 3.1% over the same period. Northern Ireland and Scotland also bucked the national price trend, still recording rises.
This is important context for the RICS September 2026 survey London weaker Notting Hill October 2026 picture: prime central London is not tracking the UK average. It is softer. We are not citing a specific price movement for Notting Hill itself, no verified figures exist for the immediate micro-market, but the qualitative direction for prime central London is unambiguous: demand is cooling faster than supply is adjusting, and that combination tends to put downward pressure on achievable prices and upward pressure on time-to-sell.
What Rising Supply and Weaker Demand Mean for Negotiating in Notting Hill
Put the two headline RICS figures together, instructions to sell up for the first time in over a year, buyer enquiries down for the first time since March, and the implication for W11, W2 and W10 is straightforward: buyers have more choice, and less urgency.
Practical consequences likely to show up in Notting Hill transactions over the coming weeks include:
- Longer marketing times. With agreed sales down and sales expectations slipping to -6%, vendors should expect viewings to convert more slowly than during the stronger spring market.
- Increased down-valuation risk. Lenders' valuers are likely to be more conservative when comparable evidence shows a softening trend, particularly on stucco houses and larger conversions where comparables are thinner.
- More price-chipping after survey. In a buyer's market, a building survey that flags render defects, damp or timber decay becomes genuine negotiating leverage rather than a formality, buyers are increasingly using findings to renegotiate rather than walk away.
- Stronger lettings backdrop. Tenant demand (+23%) and rent expectations (+37%) suggest landlords and leaseholders considering letting rather than selling have a comparatively firmer market to fall back on.
Common Defects Surveyors Find in Notting Hill's Period Stock
Notting Hill's stucco-fronted Victorian terraces and their basement conversions are architecturally prized but structurally demanding. In a market where buyers are more willing to negotiate on condition, the defects that regularly surface in building surveys carry more financial weight than in a seller's market. The most common issues we encounter include:
- Render and stucco failure, cracking, hollow sections and water ingress behind painted render, often masking deeper masonry problems.
- Parapet gutter defects, concealed gutters behind parapet walls are prone to blockage and overflow, leading to hidden water damage in roof voids and top-floor ceilings.
- Timber decay, rot and insect damage in floor joists and roof timbers, particularly where Victorian ventilation has been compromised by later refurbishment.
- Damp in lower-ground floors, basement and lower-ground conversions are especially vulnerable to rising and penetrating damp, exacerbated by inadequate tanking or drainage.
A full structural survey or a Level 3 RICS building survey will typically identify these issues before they become negotiating flashpoints. For buyers unsure which level of inspection suits a period conversion versus a straightforward flat, our guide on the difference between Level 2 and Level 3 surveys explains the distinction clearly. Where damp is suspected, a dedicated damp survey or structural crack assessment can pinpoint the cause before exchange.
Why Sellers Should Fix or Disclose Issues Before Listing
In the current climate, more instructions competing for fewer active buyers, a property that reaches market with unresolved defects is at a structural disadvantage. Buyers conducting surveys in a cautious market are more likely to use findings to chip the price, delay exchange, or withdraw entirely. Commissioning a condition survey report before listing allows sellers to either fix problems in advance or disclose them transparently with costed estimates, which tends to preserve negotiating position far better than a defect discovered mid-transaction.
What This Means for You
Whether buying, selling or holding a lease in Notting Hill, Holland Park, Kensington or Bayswater, the softer conditions described in the RICS September 2026 survey make professional advice more valuable, not less.
- Buyers should commission an independent RICS home survey before making an offer, giving leverage to negotiate on genuine defects rather than guesswork.
- Sellers should consider a pre-listing condition survey to identify and address issues like stucco failure or lower-ground damp before buyers find them first.
- Leaseholders weighing up lease extensions in a softer sales market should review our guide to valuing freehold versus leasehold under the 2026 reforms.
- Anyone facing a mortgage down-valuation can request an independent valuation report in Notting Hill to challenge or support a lender's figure.

Frequently Asked Questions
What is a RICS net balance figure?
It is the percentage of surveyors reporting a rise in an indicator minus the percentage reporting a fall. A negative net balance means more surveyors saw declines than increases; it does not measure the size of the change.
Does the RICS September 2026 survey give an actual Notting Hill house price figure?
No. The survey reports national and regional net balances, not street-level prices. London overall was weaker than the UK average, and prime central London is reasonably assumed to be following that softer trend, but no specific Notting Hill figures exist in the data.
Why did buyer enquiries fall in September 2026?
RICS's Tarrant Parsons attributed the weakening to a renewed rise in interest rate expectations, consistent with mortgage rates sitting at a three-year high and Bank Rate at 3.75%.
Is now a good time to sell in Notting Hill?
With instructions to sell rising and buyer enquiries falling, sellers face more competition. A well-presented property with issues disclosed or fixed upfront, supported by a professional condition survey, is better placed to hold its price.
What should buyers watch for in a stucco-fronted terrace?
Common issues include render and stucco cracking, parapet gutter defects, timber decay, and damp in lower-ground floors, all of which a Level 3 building survey is designed to identify.
How does the lettings market compare to sales right now?
Lettings are notably stronger: tenant demand rose to +23% and three-month rent expectations hit +37%, a marked contrast with the weakening sales market.
