£10.7 billion. That is how much buy-to-let lending UK-wide hit in the second quarter of 2026, a 25% jump year on year. Yet behind that headline number, new landlord purchases eased slightly. For anyone tracking buy-to-let lending Kingston October 2026 trends, this split between booming remortgage activity and cooling purchase demand tells a much more interesting story than the top-line figure suggests.
UK Finance's data, reported by Property Industry Eye on 22 October 2026, shows a market that is stabilising rather than expanding. For Kingston upon Thames, Surbiton, New Malden and the neighbouring Richmond borough, that distinction matters enormously, especially with an Autumn Budget on 28 October 2026 and a Bank of England rate decision on 5 November 2026 landing within days of each other.
Key Takeaways
- UK buy-to-let lending reached £10.7bn in Q2 2026, up 25% annually, but much of that growth reflects a weak comparison period after April 2025 stamp duty changes.
- New buy-to-let purchase mortgages fell quarter-on-quarter, down 845 loans from Q1 2026, even as they rose 23% year on year.
- Remortgaging is the dominant force: 39,631 buy-to-let remortgages in Q2, up 17.6% annually and higher than Q1.
- Average buy-to-let rates rose to 4.82%, and landlords face a two-percentage-point income tax rise on rental profits from April 2027.
- For Kingston landlords, this is a refinancing and evidence-gathering market, independent valuations and condition surveys matter more than ever.
Buy-to-Let Lending Kingston October 2026: The National Picture
The UK Finance figures for Q2 2026 (April to June) show:
| Metric | Q2 2026 | Change |
|---|---|---|
| Total buy-to-let loans | 58,051 | +20.6% year on year |
| Total value | £10.7bn | +25% year on year |
| New purchase mortgages | 16,026 | +23% YoY, -845 vs Q1 |
| Remortgages | 39,631 | +17.6% YoY, +470 vs Q1 |
| Average gross rental yield | 7.27% | vs 7.26% a year earlier |
| Average new BTL rate | 4.82% | up from 4.70% in Q1 |
| Average interest cover ratio | 217% | vs 210% a year earlier |
James Tatch, head of analytics at UK Finance, summed it up precisely: "The latest figures point to a more resilient buy-to-let market, but the headline growth should be viewed in context." He flagged that remortgaging edged up while purchase lending eased, and warned that higher borrowing costs could keep restraining demand.
This is the key point for anyone following buy-to-let lending Kingston October 2026 data: the 25% growth figure is flattered by a weak Q2 2025, when the April 2025 stamp duty changes had already pulled transactions forward. Strip that distortion away, and the real story is a market where existing landlords are refinancing in large numbers, while new buyers are becoming more cautious.
Why Remortgaging Is Outpacing Purchases
Several forces are pushing Kingston landlords toward refinancing rather than buying:
- Rate normalisation after fixed deals expire. Many landlords locked in rates years ago and are now rolling onto fresh deals at 4.82% average, up from 4.70% in Q1.
- Arrears falling, lender confidence rising. Buy-to-let arrears above 2.5% of balance dropped to 8,390 cases, down 25.6% annually, and possessions fell 20.3% to 630. Lenders are more willing to offer competitive remortgage terms to low-risk borrowers with strong rental evidence.
- Outstanding fixed-rate mortgages shrinking. The stock of fixed-rate buy-to-let loans fell 0.7% to 1.46 million, and variable-rate loans dropped 3% to 450,000, both signalling a wave of deals maturing and needing renewal.
For Kingston landlords, this means the practical question for late 2026 is rarely "should I buy another property?" It is "how do I secure the best terms on my existing portfolio?"
The Local Context: London Prices Down, Rents Up
ONS data released 21 October 2026 adds further texture. London house prices fell 2.2% in the year to August 2026, while the UK average rose 0.9% to £273,000. Meanwhile, private rents climbed 3.8% nationwide to an average of £1,406 a month.
This divergence, softer capital values in London boroughs like Kingston, paired with rising rents, is precisely why the average rental yield of 7.27% has held steady nationally. For landlords in Kingston, Surbiton and New Malden, rental income is doing the heavy lifting on returns even as property values in the capital lag behind the rest of the UK.
Why Valuation Evidence Matters More Than Ever
When lenders assess a remortgage application, they are not just checking the borrower's income. They are scrutinising:
- Current market value of the property, often via an automated valuation model that may not reflect genuine local conditions
- Rental income evidence against the interest cover ratio requirement, currently averaging 217% nationally
- Property condition, since disrepair or unresolved defects can affect both valuation and mortgageability
This is where an independent RICS valuation becomes essential. Automated valuation models frequently fail to capture nuances specific to Kingston's housing stock, period conversions in Surbiton, new-build flats in Kingston town centre, or ex-local-authority stock in New Malden. A professional surveyor's report gives landlords leverage when negotiating with lenders and can prevent an unfavourable automated valuation from derailing a remortgage.
An independent valuation isn't just paperwork, it's often the difference between a competitive rate and a declined application.
A condition survey carries equal weight. With London property prices softer than the rest of the UK, lenders are increasingly cautious about properties showing visible wear, damp, or deferred maintenance. A pre-remortgage condition survey identifies issues before a lender's surveyor does, giving landlords time to address problems or adjust their strategy.
Tax Changes Add Urgency
Landlords also need to factor in the Autumn Budget on 28 October 2026 and the confirmed two-percentage-point rise in income tax on rental profits from April 2027. Combined with the Bank of England's rate decision on 5 November 2026, Kingston landlords face a narrow window to lock in favourable remortgage terms before borrowing costs or tax liabilities shift further.
Q4 2026 Checklist for Kingston Landlords
- Review maturing fixed-rate deals now. With average rates up to 4.82%, early action avoids reverting to a lender's standard variable rate.
- Commission an independent RICS valuation ahead of any remortgage application, particularly for properties in Kingston's more varied housing stock.
- Order a condition survey to catch issues before a lender's valuer does.
- Recalculate rental yield and interest cover ratio using current rent levels, remember UK private rents rose to £1,406 a month.
- Model the April 2027 tax change into cash flow projections before deciding whether to hold, refinance, or sell.
- Watch the 5 November Bank of England decision closely, as it will shape remortgage pricing into 2027.
Frequently Asked Questions
Is now a good time to buy a buy-to-let property in Kingston?
Purchase lending has eased slightly, and London prices are softer than the UK average. This may suit cautious buyers, but rising rates and upcoming tax changes mean careful affordability checks are essential.
Why did buy-to-let lending jump 25% if purchases fell?
The increase is driven largely by remortgaging activity and a weak comparison quarter in 2025, not genuine market expansion.
How does an independent valuation help with a buy-to-let remortgage?
It provides evidence-based value that can counter an unfavourable automated lender valuation, potentially improving loan terms.
What rental yield should Kingston landlords expect?
The national average is 7.27%, though local figures vary by property type and location within the borough.
Should landlords worry about the 2027 tax change now?
Yes. Planning ahead of the April 2027 income tax rise on rental profits allows time to adjust pricing, structure, or ownership strategy.
Conclusion
The Q2 2026 UK Finance figures confirm that buy-to-let lending Kingston October 2026 activity is being driven by refinancing, not expansion. Landlords renewing deals should prioritise independent RICS valuations and condition surveys to secure the strongest possible terms before rates shift further and the April 2027 tax change takes effect. Acting before year-end, rather than waiting, remains the clearest path to protecting returns in this more cautious market.
