This week delivered one of the more striking contrasts the London property market has produced in recent years.
On one hand, asking prices for newly listed homes recorded their sharpest June fall since 2012. On the other, London stood out as the only UK region where rental demand is actually rising.
For anyone weighing up a sale, a purchase or a buy-to-let in South West London, this is a week that rewards a closer look.
UK and London property news: asking prices post worst June in 14 years
According to the latest Rightmove House Price Index, published on 15 June, the average asking price for newly listed homes fell 0.6% in June, a drop of £2,113, taking the typical figure to £376,191. That is the largest June decline since 2012.
Normally June sits firmly within the spring selling season, when sellers price with confidence and momentum carries the market into summer. This year that pattern has broken. The fall has been driven by three forces working together:
- High supply. The number of homes coming to market remains elevated, handing buyers more choice and more negotiating power.
- Price-sensitive buyers. With mortgage rates still higher than many would like, demand is cautious and discretionary.
- An early summer slowdown. Seasonal distractions, including the football World Cup, appear to have pulled activity forward and dampened momentum.
Propertymark chief executive Nathan Emerson noted the more cautious mood among buyers, while Knight Frank’s Tom Bill pointed to wider geopolitical uncertainty, including the conflict in the Middle East, as having sapped seasonal energy. Bill is forecasting modest UK house price growth of around 1.5% across 2026 as higher mortgage rates and political uncertainty weigh on demand.
A 0.6% drop in asking prices does not mean transacted values are collapsing. It signals sellers recalibrating expectations to meet a buyer pool that simply has more leverage than it did a year ago.
Encouragingly, sales activity has held up better than the headline suggests. May buyer demand was around 10% below the same point last year but broadly in line with 2026 levels overall, suggesting a market that is steady rather than stalling. This echoes themes we explored in our earlier coverage of London house prices facing falls as supply hits highs.
South London house prices: what the data means locally
National averages always mask the local picture, and that is especially true across South and South West London. Boroughs such as Wandsworth, Richmond, Kingston and Merton remain underpinned by strong schools, green space and reliable transport links, which tends to cushion them against the sharpest swings.
That said, the higher-value end of the market, including parts of Chelsea, Fulham, Putney and Wimbledon, is more exposed to price sensitivity. Buyers at these levels are acutely aware of stamp duty, borrowing costs and global uncertainty, and they are negotiating accordingly. Realistic pricing from the outset is now the single biggest factor in achieving a sale within a sensible timeframe.
For sellers in areas such as Clapham, Battersea and Balham, the message is clear. With supply elevated, standing out matters. Presentation, accurate valuation and an experienced local agent who understands street-level demand are all essential. If you are considering a move, our property valuation service offers a grounded view of where your home sits in today’s market.
A note for buyers and investors
A softer pricing environment is rarely bad news for committed buyers and investors. More choice and greater negotiating room create genuine opportunities, particularly for those purchasing for the long term. For anyone exploring property investment in London, conditions like these reward patience and discipline rather than panic.

The flip side: London rental demand is climbing
While the sales market cools, the rental market tells a very different story. Zoopla’s Rental Market Report, published on 11 June, confirmed that London is the only UK region where rental demand is rising, up 6% in the four weeks to 31 May 2026.
The dynamic is straightforward. With mortgage rates keeping homeownership out of reach for many would-be first-time buyers, more people are staying in the rental market for longer. That sustained demand is feeding directly into rents.
| Metric | Figure (June 2026) |
|---|---|
| Average UK new-let rent | £1,321 per month |
| UK rental inflation (year-on-year) | 2.1% |
| London rental inflation | 2.2% (up from 1.9% a year ago) |
| London rental demand change | +6% (four weeks to 31 May) |
| Forecast rental inflation, rest of 2026 | 2% to 3% |
For landlords across South West London property hotspots, this is meaningful. Rising demand and modest rental inflation support yields at a time when capital values are flat to falling. The investment case for buy-to-let in well-connected South London neighbourhoods remains intact, provided landlords manage costs and compliance carefully.
If you own rental property in the area, working with an experienced lettings agency in South London can help you capture this demand while keeping voids low and tenant quality high.
Mortgage rates and the Bank of England backdrop
Mortgage costs remain the thread connecting both halves of this week’s story. Higher rates are simultaneously cooling buyer demand and propping up the rental market by keeping first-time buyers renting for longer.
Knight Frank’s commentary this week reinforced that affordability, not appetite, is the constraint. Buyers want to move, but the maths of monthly repayments at current rates forces caution. Until borrowing costs ease more meaningfully, expect this two-speed market to persist: subdued sales pricing alongside resilient rental demand.
Renters’ Rights Act: a fresh policy update for landlords
On 8 June, the government updated its Renters’ Rights Act Information Sheet 2026 guidance. The refreshed page adds detail on assured periodic tenancies and clarifies the position for landlords who served a valid Section 8 or Section 21 notice before 1 May 2026.
Crucially, the guidance reiterates the 31 May 2026 deadline for serving the Information Sheet to tenants, with potential fines of up to £7,000 for non-compliance. For South London landlords, this is a clear reminder that the regulatory environment is tightening and that documentation must be watertight.
We have covered the broader implications in our explainer on how the Renters’ Rights Act affects London landlords. The key takeaway this week is simple: stay current, serve the right paperwork on time, and seek professional support if you are unsure. The cost of getting compliance wrong now materially outweighs the cost of getting expert help.
What it means in practice
- Review every tenancy to confirm the Information Sheet has been served correctly.
- Understand how assured periodic tenancies apply to your portfolio.
- Check the status of any Section 8 or Section 21 notices served before 1 May 2026.
- Keep records that demonstrate compliance, ready for inspection.
The OS Perspective
This week crystallises a market that is increasingly defined by divergence. Sales pricing is soft and buyer power is rising, yet rental demand in London is strengthening and rents are climbing. For sellers, realism is everything. For buyers and investors, choice and negotiating room are quietly improving. For landlords, demand is healthy but compliance has never mattered more.
In environments like this, local expertise outperforms broad assumptions. South West London continues to demonstrate the resilience that has long underpinned its appeal, but success in 2026 will hinge on accurate pricing, disciplined buying and meticulous landlord management.
