A small move in the uphold rate, a much bigger move in volume
In the most recent 90-day window tracked by Veste, Barclays Bank UK PLC's uphold rate on published Financial Ombudsman decisions stood at 11.4%, down from 12.8% in the prior 90-day window. That is a fall of 1.4 percentage points. Over the same comparison, the number of decisions published fell far more sharply: from 584 in the prior window to 281 in the latest one, a drop of 303 decisions, or 51.9%.
Both windows meet Veste's minimum sample threshold of 30 decisions, so the comparison is not resting on a handful of cases. But the scale of the volume change is worth sitting with before drawing any conclusion about the rate. A fall of this size in the number of published decisions changes the composition of what is being measured almost as much as any shift in Barclays' underlying handling of complaints would. Fewer decisions means each case carries proportionally more weight in the resulting percentage, and it also means the mix of issue types, products and case ages feeding into that percentage can shift for reasons that have nothing to do with how Barclays is treating any individual customer.
Put simply: a 1.4 percentage point move on 281 decisions is a modest movement, and it follows a much larger contraction in the volume of decisions being published about Barclays in the first place.
The headline numbers
Across the full period Veste holds data for Barclays Bank UK PLC, from first sighting on 2018-11-12 to the most recent decision on 2026-06-29, the ombudsman has published 11,208 decisions concerning the firm. Of these, 1,631 were upheld in the complainant's favour, 1,543 were partially upheld, and 8,034 were not upheld. That produces an all-time uphold rate, on Veste's definition of (upheld plus half of partially upheld, divided by total) of 21.4%.
That all-time figure sits below the wider corpus baseline. Across the 403,325 decisions with an outcome that Veste holds in total, spanning the whole dataset from 2013-04-02 to 2026-06-29, the corpus-wide uphold rate is 28.8%. Barclays' all-time rate of 21.4% is therefore some way beneath that broader benchmark, though readers should note the corpus baseline covers many firms, products and years that are not directly comparable to any single institution's recent run of decisions.
What the 24-month trend shows
The monthly series Veste tracks for Barclays runs for 24 months, from 2024-07-01 to 2026-06-01, and it tells a more gradual and more consistent story than the quarter-on-quarter figures alone would suggest.
In July 2024, Barclays' monthly uphold rate stood at 28.7% on 82 decisions. It rose to 32.4% in August 2024 (102 decisions) and 30.0% in September 2024 (125 decisions), before beginning a broadly downward drift. By January 2025 the rate had fallen to 19.9% on 103 decisions. It continued easing through the spring and summer of 2025, reaching 12.5% in May 2025 (104 decisions) and 14.5% in September 2025, a month that also saw a jump in volume to 200 decisions, the highest monthly total in the series.
The decline has continued into 2026. January 2026 recorded a rate of 14.4% on 142 decisions, February 13.0% on 169 decisions, and March 11.9% on 273 decisions, the largest single month in the whole 24-month run. The three most recent months for which Veste holds data show the rate at its lowest points in the series: 13.5% in April 2026 (74 decisions), 11.2% in May 2026 (98 decisions), and 10.1% in June 2026 (109 decisions).
Seen against that backdrop, the quarter-on-quarter fall from 12.8% to 11.4% looks less like a discrete event and more like the tail end of a longer downward trend that has been running since late 2024. The rate has not moved sharply in the latest quarter so much as continued sliding along broadly the same trajectory it has followed for well over a year.
The annual picture
Veste's year-on-year figures reinforce this. In 2022, Barclays recorded 1,526 decisions with an uphold rate of 21.8%. In 2023, the total was 1,284 decisions at 22.4%, essentially flat on the year before. Then in 2024, the rate rose to 27.7% on 1,491 decisions, the highest of the five years in this series. It fell back to 16.2% in 2025 on a larger total of 1,518 decisions, and for 2026 to date the rate stands at 12.4% on 865 decisions.
All five years meet Veste's minimum sample size, so these are firm comparisons rather than noise from small numbers. The pattern across 2022 to 2026 is not a straight line: the rate rose notably in 2024 before falling in both 2025 and the opening months of 2026. Readers should be cautious about reading a single, uninterrupted downward trend into this without acknowledging the rise that preceded it.
What might be driving the numbers, and what the data cannot say
Veste's related-category data offers some context on the types of complaint that make up Barclays' overall published caseload, though these figures are drawn from the wider claim-category dataset rather than being filtered to Barclays alone, and should be read as background rather than as an explanation specific to this firm.
Fraud reimbursement complaints relating to authorised push payment scams show an uphold rate of 13.5% across 1,694 decisions in Veste's data, a category that sits close to Barclays' recent monthly rates. Card and payment disputes show an uphold rate of 14.0% across 1,009 decisions. By contrast, categories such as PPI mis-selling (29.3% across 1,319 decisions) and service failures generally (26.7% across 1,248 decisions) show materially higher uphold rates. If a firm's published caseload shifts in composition, for example towards more fraud and payment-dispute cases and fewer service-failure or lending-related complaints, the overall uphold rate would be expected to move without any change in how any individual type of complaint is decided. Veste's data does not allow us to confirm that such a shift in mix, as opposed to any other factor, explains the pattern seen at Barclays, but it is a plausible contributing element worth flagging for readers assessing the numbers.
Individual decisions as illustration
Four recent published decisions concerning Barclays Bank UK PLC, all dated between 26 and 29 June 2026, were not upheld. They illustrate the kinds of cases making up the current caseload rather than proving anything about the broader trend.
One case (DRN-6335021) concerned disputed transactions made on a shared device where a customer's son had access to her card details via a mobile payment app; the ombudsman found the customer had created apparent authority for the payments under the Payment Service Regulations 2017, making them authorised.
Another (DRN-6367192) involved a couple who lost £242,500 to investment and recovery scams. The ombudsman found that although Barclays could have questioned the customer more closely about payments it had blocked, she had consistently provided plausible explanations and had concealed the scam from family despite warnings, and concluded that further intervention would not have changed the outcome.
A third (DRN-6449346) concerned a disputed £2,000 payment which the customer said had been altered by a taxi driver without consent; the ombudsman found the payment was properly authenticated on the customer's own device and concluded he had most likely entered the amount himself in error.
A fourth (DRN-6449650) involved a customer who said he had lost £6,250 to an investment scam via cryptocurrency payments; Barclays had already refunded half the sum, and the ombudsman did not extend this further, citing insufficient evidence that the funds had reached a scammer.
These four cases are presented as examples of the types of dispute reaching the ombudsman about this firm in the most recent period, not as evidence of a pattern in how such cases are typically decided.
What the data does and does not tell us
Veste's data confirms that Barclays' uphold rate fell modestly between the two most recent 90-day windows, and that this sits within a longer downward drift visible across 24 months of monthly figures and reflected in the year-on-year totals since 2024. It also confirms that the volume of published decisions concerning Barclays fell far more sharply than the rate did in the latest quarter.
What the data cannot tell us is why. Veste's figures do not capture underlying complaint volumes submitted directly to Barclays, only the subset that reach a published ombudsman decision, and the ombudsman's publication pipeline can itself introduce timing effects unrelated to any change in a firm's conduct. Firms are also counted in this data by the exact business name recorded on each decision, so Barclays Bank UK PLC is treated separately from any other entity within the same banking group that might appear under a different registered name; the figures here relate only to decisions recorded against this specific entity.
The practical implication
For anyone tracking Barclays' ombudsman record, the more informative signal is the multi-year drift visible in the monthly series, not the single quarter-on-quarter comparison. A 1.4 percentage point move on a much smaller sample of decisions is the kind of change that can arise from ordinary variation in case mix and timing as easily as from any shift in how complaints are being resolved. The steadier decline from the 2024 peak of 27.7% down toward the 10 to 13% range seen in the first half of 2026 is a larger and more sustained pattern, and it is this longer series, rather than any single quarter, that offers the more reliable basis for judging direction.
