A small rise, a big drop in volume
Between the prior 90-day window and the most recent one, the uphold rate for decisions naming Mitsubishi HC Capital UK Plc rose from 3.8% to 6.7%, an increase of 2.9 percentage points. Over the same two windows, the number of published decisions fell from 327 to 126, a drop of 201 cases, or 61.5%. Both windows meet Veste's minimum sample threshold of 30 decisions, so the comparison is not resting on a handful of cases. But a rise of a few percentage points on a falling base is a modest movement, and it needs to be read alongside the much larger swings visible in the monthly series before any firm conclusion is drawn.
The uphold rate used throughout this analysis follows Veste's standard definition: upheld decisions count in full, partially upheld decisions count as half, and the result is divided by the total number of decisions in the period. On that measure, Mitsubishi HC Capital UK Plc's uphold rate across all 1,114 decisions published since first appearing in the corpus on 2022-03-28 stands at 14.0%, made up of 136 decisions upheld in full, 41 partially upheld, and 937 not upheld.
The monthly picture is more volatile than the headline suggests
Veste's monthly series covers 25 months, from 2024-06-01 to 2026-06-01. It shows an uphold rate that has moved substantially over that period, from as high as 66.7% in September 2024 (on 21 decisions) down to 0.0% in April 2025, August 2025 and May 2026 (on volumes ranging from 6 to 22 decisions in those months). The most recent full months in the series, December 2025 through March 2026, each carried far higher decision volumes than earlier in the series, ranging from 108 to 163 decisions a month, with uphold rates in a narrow band between 2.3% and 6.8%.
This matters for interpreting the 90-day comparison. The current 90-day window's higher uphold rate of 6.7% sits within the range already seen in those high-volume months, rather than representing a sharp break from them. The prior 90-day window's lower rate of 3.8% appears to have been pulled down by the very large volumes and very low uphold rates recorded in December 2025 and February 2026 specifically. In other words, the 2.9 percentage point rise looks at least in part like the comparison window shifting away from a particularly low-uphold-rate cluster of months, rather than a new and separate trend emerging.
The longer-term, year-on-year context
Looking year by year, the uphold rate for Mitsubishi HC Capital UK Plc has fallen substantially since 2022. In 2022, on a total of 76 decisions, the uphold rate was 25.0%. In 2023, on 128 decisions, it was 15.6%. It rose again in 2024, on 204 decisions, to 29.9%, the highest of the five years shown. It then fell to 12.1% in 2025 on 313 decisions, and has fallen further still in the partial year 2026, to 4.7% on 393 decisions so far. All five years meet Veste's minimum sample size, so these year-on-year figures can be reported with reasonable confidence in their sample sizes, even though the underlying reasons for the swings are not established by the data itself.
The pattern across the full run of years is not a steady decline. It rises and falls between 2022 and 2024 before falling in both 2025 and the year to date in 2026. The most recent 90-day uptick of 2.9 percentage points has to be seen against a backdrop where the multi-year trend, if anything, points toward a lower uphold rate, not a higher one. A short-term rise inside a longer-term fall is not necessarily contradictory, but it does mean readers should be cautious about extrapolating the latest quarter into a new direction.
What the underlying cases look like
The supplied case examples, all decided in May and June 2026, are illustrative rather than representative of the full 1,114-decision population, but they help explain the type of dispute driving the numbers. All four concern Fractional Club timeshare memberships financed through consumer credit agreements with Mitsubishi HC Capital UK Plc (in one case recorded under the near-identical name Mitsubishi HC Capital UK PLC, a reminder that Veste counts firms by the exact name recorded on each decision rather than rolling subsidiaries or name variants into a single group).
In each of the four examples, the ombudsman did not uphold the complaint. The cases involved claims under Section 75 of the Consumer Credit Act 1974 (connected lender liability for alleged misrepresentation or breach of contract by the timeshare supplier) and Section 140A (unfair credit relationship), together with allegations that suppliers had breached the Timeshare Regulations 2010 by marketing memberships as investments, and that commission arrangements had not been adequately disclosed.
A recurring theme in the reasoning is that even where a supplier may have breached the prohibition on marketing timeshares as investments, the ombudsman found this was not material to the complainant's purchasing decision, because the complainants' own evidence pointed to motivations around holiday benefits rather than investment returns. Commission levels in these cases, quoted at 4%, 5.61% and £808.44 in one instance, were found not to be disproportionately high enough to render the credit relationship unfair. Two of the four examples also involved Section 75 claims rejected as time-barred under the Limitation Act 1980, where complaints were brought more than six years after the original purchase, in one case relating to a 2012 purchase.
These four decisions cannot be used to characterise the whole 1,114-decision book, and they are shown here as illustration of dispute type rather than proof of an overall pattern. But their consistency, all not upheld, all concerning the same product category and legal grounds, is consistent with the low uphold rates recorded across the high-volume months of December 2025 to March 2026, when timeshare-financing disputes of this kind appear to have made up a substantial share of the total.
How this compares with related complaint categories
Veste's related categories give some further context, though these figures cover the wider corpus of decisions in each category, not Mitsubishi HC Capital UK Plc specifically. Complaints about goods and services under Section 75 have an uphold rate of 9.1% across 635 decisions. Irresponsible lending complaints have an uphold rate of 18.2% across 168 decisions. Other regulated complaints have an uphold rate of 29.0% across 105 decisions, and PCP or HP mis-selling complaints have an uphold rate of 5.3% across 66 decisions. Mitsubishi HC Capital UK Plc's overall uphold rate of 14.0% sits between the Section 75 goods-and-services figure and the irresponsible lending figure, though direct comparison is limited because these category totals span many firms, not one.
Against the baseline uphold rate for the entire corpus of 401,044 decisions with an outcome, which stands at 28.8%, Mitsubishi HC Capital UK Plc's all-time rate of 14.0% is markedly lower. The gap has widened further in the most recent full years: 2025's rate of 12.1% and the 2026 year-to-date rate of 4.7% both sit well below the corpus-wide baseline.
What this does and does not show
The data shows that a defined set of published Ombudsman decisions naming Mitsubishi HC Capital UK Plc carried a somewhat higher uphold rate in the most recent 90-day window than in the window before it, on considerably fewer decisions. It shows that the firm's uphold rate has fallen across recent full calendar years, from 29.9% in 2024 to 12.1% in 2025 and 4.7% so far in 2026. And it shows that a cluster of decisions from late 2025 through early 2026, involving very high monthly volumes, coincided with some of the lowest uphold rates in the 25-month series.
What the data does not show is why volumes rose so sharply in December 2025 to March 2026, why they have since fallen back, or what proportion of the underlying dispute types (such as the timeshare-financing complaints illustrated above) made up those high-volume months versus the more recent, lower-volume ones. Published Ombudsman decisions are also not the same population as all complaints made to the firm; many complaints are resolved before reaching a published decision, and this dataset only captures the ones that were published.
The takeaway
The 2.9 percentage point rise in Mitsubishi HC Capital UK Plc's uphold rate between the two most recent 90-day windows is a real, measured movement on adequately sized samples, but it sits inside a range of monthly variation that has been considerably wider over the past two years, and it runs against a longer-term downward trend across 2025 and 2026 to date. Readers should treat it as a modest short-term fluctuation worth monitoring in subsequent quarters, not as evidence of a reversal in the firm's overall trajectory as recorded in published Ombudsman decisions.
