Rent Arrears Hit 18% of Tenancies as Average Debt Outstrips Deposits by £579: What Reposit’s Q3 2026 Data Means for Notting Hill Landlords (November 2026)

Eighteen percent. That is the share of tenancies now falling behind on rent, according to new figures released this week, and it means the average tenant debt has climbed well past what a standard deposit can cover. For landlords and investors across Notting Hill, Kensington and west London, the numbers published on 5 November 2026 are a timely prompt to check how exposed their own properties really are. This article looks at what the data on rent arrears 2026 Notting Hill landlords deposits actually shows, where the limits of that data lie, and what practical steps landlords and tenants should take now.

The figures come from Reposit, a company that provides an insurance-backed alternative to cash deposits, as reported by Property Industry Eye on 5 November 2026. They land in the same week as a Bank of England rate rise and ahead of the full effect of the Renters' Rights Act being felt across the sector, a combination that makes the subject of rent arrears 2026 Notting Hill landlords deposits particularly relevant right now.

Key Takeaways

• Reposit's data shows 18% of tenancies fell into arrears in Q3 2026, up from 12% a year earlier, a 50% relative rise.
• The average amount owed, £1,837, is now £579 higher than the average five-week cash deposit of £1,258.
• The figures are from Reposit's own book, a deposit-alternative provider with a commercial interest, not an independent industry-wide survey.
• Many Notting Hill and Kensington lets exceed £50,000 a year, so the six-week deposit cap under the Tenant Fees Act 2019 often applies locally, slightly narrowing the typical shortfall.
• Wider pressures, a Bank Rate rise to 4%, rents up 3.8% year on year, and a 6% rise in possession claims, all add context to the arrears discussion.
• For Notting Hill landlords, the main practical response is stronger documentary evidence: professional inventories, condition inspections and check-out reports.

The Headline Numbers Behind Rent Arrears 2026 Notting Hill Landlords Deposits

Reposit's figures show a clear upward trend through 2026. Arrears affected 18% of tenancies in Q3 2026, against 12% in the same quarter of 2025, a 50% relative jump. Looking at the first nine months of the year, the average arrears rate was 18%, compared with 15% in the equivalent periods of both 2024 and 2025. On Reposit's own figures, 2026 is on track to be the worst year for arrears in three years.

What has changed less is the size of individual debts. The average amount owed per tenancy in arrears is £1,837, only £13 higher than twelve months ago. In other words, more tenancies are slipping into arrears, but the typical debt per case has stayed broadly flat.

The problem for landlords is how that debt compares with deposit cover. The average five-week cash deposit sits at £1,258, some £579 short of the average arrears figure. For a discussion centred on rent arrears 2026 Notting Hill landlords deposits, that gap is the single most important number: it shows a standard deposit, even where fully retained, may not cover unpaid rent alone, let alone any damage on top.

Key Figures at a Glance

Why Ben Grech Says Landlords Are Growing More Cautious

Ben Grech, chief executive of Reposit, has pointed out that unpaid rent can now exceed what a traditional deposit is able to cover, leaving landlords exposed once arrears pass a certain threshold. He has also linked the trend to the Renters' Rights Act, suggesting the changed possession process makes it harder for landlords to regain control of a property once a tenant stops paying. Grech has further argued that landlords are becoming more risk-averse generally, citing legislative change alongside high interest rates and persistent inflation as compounding pressures on the sector.

These are reasonable observations from someone close to the data, but they are also the views of an executive whose company sells a product designed to replace the cash deposit. That context matters when weighing how much emphasis to place on the figures.

Caveats: Reading the Data on Rent Arrears 2026 Notting Hill Landlords Deposits Carefully

Several limitations deserve emphasis before drawing firm conclusions about rent arrears 2026 Notting Hill landlords deposits.

• Source and scope. The figures come from Reposit's own book of business, not an independent, industry-wide survey. Reposit has not disclosed how many tenancies were analysed.
• Commercial interest. Reposit sells an insurance-backed deposit alternative, under which tenants pay a non-refundable fee equal to one week's rent instead of a deposit, while remaining liable for any sums owed. A narrative that emphasises deposit shortfalls supports the case for that product.
• No proven causal link. The data does not establish that the Renters' Rights Act caused the rise in arrears; it simply coincides with a period of legislative change.
• Recovery unclear. The figures do not show how often landlords actually lose more than the deposit in practice, nor how much unpaid rent is later recovered through other means, including court action.
• Not local data. The statistics are national. There is no breakdown for Notting Hill, Kensington or west London specifically, so local landlords should treat the figures as indicative context rather than a direct measure of conditions on their own street.

The Wider Backdrop: Rents, Rates and Possession Claims

Official data adds useful context. The Office for National Statistics recorded average UK private rent at £1,406 a month in September 2026, up 3.8% (£52) year on year. Regular wage growth over the three months to August was 3.7%, broadly in line with rent growth, while CPI inflation stood at 3.5% in September, meaning household budgets remain tightly stretched even where wages are keeping pace.

On the legal and policy side, Ministry of Justice figures show landlord possession claims in England and Wales rose 6% year on year, with 23,635 claims recorded in Q2 2026. This covers all grounds for possession, not arrears alone, so it cannot be read as proof that arrears specifically are driving more court action, but it does show the possession process is busier than a year ago.

The Renters' Rights Act's main reforms took effect in England in May 2026, abolishing Section 21 no-fault evictions and altering how landlords bring tenancies to an end. And on Thursday 5 November 2026, the day before this analysis, the Bank of England raised Bank Rate from 3.75% to 4%, its first increase since August 2023. For landlords on variable-rate mortgages, that rise adds further financial pressure at exactly the moment arrears data is drawing attention to deposit shortfalls.

What Notting Hill Landlords Should Do Now

Given the gap the Reposit data highlights between arrears and deposit cover, the practical response for landlords is less about chasing new statistics and more about tightening the paperwork and processes that protect a claim when things go wrong.

• Commission a professional inventory and schedule of condition at check-in. A detailed, dated and photographed record is the foundation of any deposit-scheme adjudication or court claim. In Notting Hill's period stucco houses and converted flats, where high-value finishes are common, disputes over fair wear and tear are frequent, making thorough documentation particularly valuable.
• Arrange mid-tenancy condition inspections. Regular, independent inspections help spot damp, leaks and disrepair early, before they escalate into costly repairs or disputes at the end of a tenancy.
• Obtain a check-out report with dilapidations evidence. Where arrears already exceed the deposit, clear evidence of any additional damage strengthens a landlord's position if further recovery action becomes necessary.
• Commission a building survey to budget for repairs. Understanding the condition and likely maintenance costs of a property helps landlords plan finances realistically, particularly against a backdrop of rising interest rates.
• Keep deposits compliant with the Tenant Fees Act 2019. Many Notting Hill and Kensington lets exceed the £50,000 annual rent threshold, meaning the six-week cap, rather than five weeks, often applies, worth checking on every tenancy.
• Take legal advice before pursuing possession. The Renters' Rights Act has changed the process; landlords considering a possession claim related to arrears should seek professional legal advice rather than relying on general guidance.

Frequently Asked Questions

Does the Reposit data apply specifically to Notting Hill?
No. The figures are national. There is no separate breakdown for Notting Hill, Kensington or wider west London, so they should be treated as general market context rather than a local measure.

Is Reposit an independent research body?
No. Reposit is a provider of an insurance-backed deposit alternative. Its figures come from its own book of business, and it has a commercial interest in highlighting the limits of cash deposits.

Does a bigger deposit solve the shortfall problem?
Not necessarily. Deposits in England are capped under the Tenant Fees Act 2019 at five weeks' rent (or six weeks where annual rent is £50,000 or more), so there is a statutory limit to how much cover a deposit alone can provide against arrears.

Has the Renters' Rights Act definitely caused more arrears?
The data does not prove this. The rise in arrears coincides with the Act's main reforms taking effect in May 2026, but Reposit's figures do not establish a direct causal link.

What should a landlord do if a tenant falls into arrears?
General good practice includes maintaining clear records of rent due and paid, communicating with the tenant early, and relying on a solid inventory and inspection history if a dispute or possession claim follows. Landlords should seek legal advice before starting any possession claim, given recent changes to the process.

Conclusion

Reposit's Q3 2026 figures add a useful, if imperfect, data point to the debate around rent arrears 2026 Notting Hill landlords deposits. The headline gap, an average arrears figure of £1,837 against an average deposit of £1,258, is a real signal that deposits alone may not always cover unpaid rent, let alone damage. But the figures come from a single commercial provider, are not London-specific, and do not prove a direct link to the Renters' Rights Act. Against a backdrop of rising Bank Rate, steady rent growth and a busier possession system, the sensible response for Notting Hill landlords is not to react to one dataset but to strengthen the evidence base on every tenancy: proper inventories, regular inspections, thorough check-out reports and sound building surveys. For anything involving possession proceedings, professional legal advice remains essential.
