London Buyer Demand Slumps as RICS Flags Southern Weakness

The week of 11 to 18 May 2026 has delivered some of the most telling data points the London property market has seen this year. The Royal Institution of Chartered Surveyors (RICS) published its April 2026 UK Residential Market Survey on Wednesday, and the message from agents on the ground was unambiguous: buyers are sitting on their hands, sellers are growing impatient, and southern England is bearing the brunt of the slowdown.

For those of us tracking South West London property day in and day out, the headline numbers will not feel like a surprise, but the regional divergence within them is worth unpacking carefully.

RICS April 2026: the headline numbers

The April survey, released on 14 May, showed a market still losing momentum rather than finding a floor. Key net balances from the survey included:

New buyer enquiries: -34% (improved marginally from -40% in March)
Newly agreed sales: -36%
Headline house price balance: -34% (worsened from -25%)
Short-term sales expectations: -32%
12-month price expectations: marginally positive, but the weakest reading since late 2023

Crucially, RICS flagged London, the South East, East Anglia and the South West as the regions showing the sharpest weakness, while the North West, North of England, Scotland and Northern Ireland proved markedly more resilient. Affordability, still tethered to elevated mortgage costs and a cautious lending environment, is doing the heavy lifting in explaining that north-south split.

“The April survey suggests that the recovery many had pencilled in for spring has been pushed back again. Buyers want clarity on rates and the wider economy before committing, and in higher-value southern markets that hesitation has the biggest price impact.” – paraphrased reflection from RICS contributors

What the Land Registry says about London prices

Rightmove’s London sold-prices page, refreshed on 15 May using HM Land Registry data through 31 March 2026, fleshes out the picture. The average sold price across the capital over the last 12 months sat at £678,331, broken down as follows:

Property type	Average sold price (12 months to March 2026)
Flats	£522,164
Terraced	£784,370
Semi-detached	£789,356
Overall London average	£678,331

That average is roughly 3% down year-on-year and 8% below the 2023 peak of £736,447. In other words, London is now firmly into its third consecutive year of trading below the post-pandemic high, a sustained correction that has barely featured in mainstream coverage but which is reshaping buyer psychology across the capital.

South West London: the affordability squeeze in microcosm

If London is the epicentre of the slowdown, South West London is its most expensive, and therefore most rate-sensitive fault line. Wandsworth, Putney, Clapham, Battersea, Fulham, Chelsea, Wimbledon, Richmond and Kingston all sit firmly in the price bracket where a 50 basis point shift in mortgage rates translates into hundreds of pounds a month on a typical mortgage.

What we are observing on the ground in mid-May tracks closely with the RICS data:

Family houses £1.5m–£3m: longer days on market, more multi-stage negotiations, and successful offers landing 5–8% below the original asking price.
One- and two-bed flats: a sturdier picture, especially around transport hubs in Clapham, Earlsfield and Putney, where first-time buyers are pricing in eventual rate relief.
Prime Chelsea and Belgravia: still relatively insulated from rate sensitivity but suffering from thin transaction volumes and increasingly cautious international buyers.

For buyers willing to engage now, the combination of softer prices and more motivated vendors is creating genuine windows of opportunity. Our team has seen a meaningful uptick in enquiries from clients exploring buying in South West London precisely because they sense the negotiating leverage has shifted.

The lettings market: a very different story

While sales activity drags, the rental side of the RICS report told an almost diametrically opposed story. Tenant demand continues to outstrip new instructions, and surveyors once again signalled that rents are expected to rise over the next 12 months.

This supply-demand imbalance has been a feature of the London market for so long it almost feels structural, but the data is worth restating: fewer landlords are coming to market, partly because of regulation, partly because of mortgage costs, and partly because some are reassessing their portfolios in the wake of the Renters’ Rights Act 2025.

For private landlords still committed to the sector, the case for professional support has rarely been stronger. Compliance, tenant vetting and void minimisation are now genuine differentiators between profitable and marginal portfolios — which is one reason we have seen growing interest in our landlord services in South West London, particularly from accidental landlords trying to decide whether to sell or hold.

What South London tenants are facing

The flip side, of course, is that tenants in Clapham, Tooting, Balham, Brixton and Streatham are continuing to compete for a shrinking pool of quality stock. Open houses in the £2,000–£3,500 per month bracket are routinely producing multiple offers within 48 hours, and well-presented family lets are letting before they hit portals. Anyone searching for a home should consider engaging a proactive London property rental search service rather than relying on portals alone.

Mortgages, the Bank of England and what comes next

The RICS contributors were unanimous that elevated mortgage costs remain the single biggest brake on the sales market. With the Bank of England holding base rate steady at recent meetings and inflation proving stickier than hoped, swap rates have not moved decisively in either direction over the past month. Fixed-rate mortgages around the 4.3%–4.8% range have become the new normal for residential borrowers with reasonable deposits.

The market is essentially pricing in a slow, patient unwind rather than a dramatic cut. For prospective buyers and investors, that has two implications:

Waiting for a rate cliff is unlikely to pay off. Any easing will be gradual, and once sentiment turns, competition will return quickly.
Yield-focused strategies are increasingly attractive. With prices off their peak and rents still rising, gross yields in pockets of South London have improved meaningfully versus 2022–23.

That second point is why investor enquiries — particularly around buy-to-let, HMOs and BRRR strategies, have held up far better than residential sales activity. Investors with cash or low loan-to-value requirements are quietly taking advantage of motivated sellers in zones 2 and 3.

Policy backdrop: regulation continues to shape behaviour

Behind the RICS data sits an evolving regulatory framework. The Renters’ Rights Act 2025 continues to filter through landlord decision-making, EPC requirements remain a topic of active consultation, and stamp duty thresholds, adjusted last year, still influence buying behaviour at the £250,000–£500,000 and £925,000+ bands that capture so much of South West London stock.

None of these factors caused the slowdown on their own, but together they help explain why so many landlords and homeowners are choosing patience over action. For those weighing up whether to sell, our perspective remains that pricing realistically and presenting impeccably are now non-negotiable — a theme echoed across this week’s commentary in PropertyWire and Property Industry Eye.

Our take: a buyer’s market with a short shelf life

Pulling the threads together, the week’s data confirms what experienced operators in the UK and London property news cycle have been signalling for months. London – and South West London in particular – is in a clear buyer’s market for the first time in a long while, but it is unlikely to last indefinitely.

For motivated buyers, investors and downsizers willing to negotiate firmly and move decisively, the next two quarters could prove unusually rewarding. For landlords, the rental side of the market continues to offer income strength even as capital values consolidate.

The risk, as ever, is hesitation in both directions: buyers waiting for a phantom rate cut, and sellers clinging to 2022 valuations. The bridge between those two camps is where the most interesting deals, both on and off-market, are currently being struck.
