A category, not a single firm, moving together
"Insurance provider" is not one company. It is Veste's grouping for insurance underwriters and direct writers, including Aviva, Direct Line, Admiral, LV=, Ageas, Zurich, Allianz, RSA, Hastings and Esure, and it includes decisions recorded under 104,589 published Financial Ombudsman rulings between 2013-04-03 and 2026-06-29. Within that broad total, 27,736 decisions were upheld, 10,715 partially upheld and 66,134 not upheld, giving a lifetime uphold rate of 31.6%.
The latest movement in that category is what prompts this analysis. Comparing two 90-day windows anchored to the newest decision date in the corpus, the uphold rate fell from 30.3% in the prior window to 24.5% in the current one, a drop of 5.8 percentage points. Over the same comparison, decision volume fell from 2,537 to 1,758, a decline of 779 decisions, or 30.7%. Both windows meet Veste's minimum sample threshold of 30 decisions, so this is not a case of a handful of rulings swinging the percentage. But a falling uphold rate alongside a substantial drop in volume is worth examining rather than simply reporting.
The numbers behind the movement
The current 90-day window contains 1,758 decisions with a 24.5% uphold rate. The prior window contains 2,537 decisions at 30.3%. That is a meaningful change in both the numerator and the denominator: fewer cases were decided, and a smaller proportion of those decided went the complainant's way, at least in whole or in part.
Context from the monthly series, which runs for 25 months from 2024-06-01 to 2026-06-01, shows this is not a sudden cliff-edge but the tail of a longer slide. Monthly uphold rates for insurance providers sat above 38% for much of the second half of 2024 (for example 42.0% in July 2024, 38.5% in August 2024, 40.1% in September 2024). By the second half of 2025, monthly rates had drifted down into the low-to-mid 30s (33.1% in July 2025, 31.7% in September 2025). By early-to-mid 2026, the rate had fallen further still: 27.9% in March 2026, 23.8% in April 2026, 24.4% in May 2026, and 25.1% in June 2026. The most recent 90-day window sits at the lower end of this longer downward drift, rather than representing an isolated shock.
Volumes also moved. Monthly totals rose through late 2024 and into 2025, peaking at 1,011 decisions in September 2025 and 1,064 in March 2026, before falling back to 496 in April 2026, 579 in May 2026 and 683 in June 2026. The current 90-day window's total of 1,758 decisions reflects that recent pull-back in monthly volume as much as anything else. A smaller published caseload naturally produces a less stable percentage, and Veste's own guidance is that comparisons resting on falling samples should be read cautiously even where the minimum sample size is technically met.
The year-on-year picture
Looking across full calendar years gives a longer baseline than the 90-day comparison. In 2022, insurance providers recorded 7,794 decisions at a 29.7% uphold rate. In 2023, that rose to 8,295 decisions at 39.5%. In 2024, the total was 7,828 decisions at 39.9%, the highest annual rate in this series. In 2025, the total climbed to 8,371 decisions but the uphold rate fell back to 34.7%. So far in 2026, with 4,295 decisions recorded, the rate stands at 27.9%.
That sequence, 29.7% in 2022, rising to 39.5% and 39.9% in 2023 and 2024, then declining to 34.7% in 2025 and 27.9% so far in 2026, shows that the current 90-day figure of 24.5% is consistent with a multi-year downward trajectory rather than a one-off dip. It is also worth noting that the category's lifetime uphold rate of 31.6% sits above the corpus-wide baseline of 28.8% across all 403,326 decisions Veste holds with an outcome, meaning insurance providers as a group have historically been upheld somewhat more often than the average firm across all sectors, even as that gap appears to be narrowing.
What the firm mix shows
Because "Insurance provider" aggregates multiple legal entities, the category-level rate can shift if the mix of firms contributing decisions changes, even without any single firm's behaviour changing. Veste's data does not tell us the firm mix within the two 90-day windows specifically, but the spread of uphold rates across firms within the category over its full history is wide enough to matter.
Among firms with sufficient sample size in the supplied data, Ageas Insurance Limited has the highest uphold rate at 39.8% across 3,009 decisions. AXA Insurance UK Plc sits at 34.6% across 3,733 decisions, and UK Insurance Limited at 32.9% across 3,739 decisions. At the other end, AXA France IARD has an uphold rate of just 7.6% across 3,051 decisions, and Allianz Insurance Plc sits at 19.0% across 2,436 decisions. Aviva Insurance Limited, the largest single contributor in this dataset with 5,113 decisions, has an uphold rate of 26.6%, close to the current 90-day category figure. A separate entity, Aviva Life & Pensions UK Limited, records 2,461 decisions at 23.2%, while U K Insurance Limited (recorded separately from UK Insurance Limited due to how business names appear on individual decisions) has 2,899 decisions at 28.2%.
This spread illustrates a structural point rather than a criticism of any firm: because subsidiaries and differently-formatted business names are counted separately rather than rolled up under a parent group, a shift in which entities are publishing decisions in a given quarter can move the category average without any underlying change in outcomes at firm level. Veste counts firms by the name recorded on each decision, so UK Insurance Limited and U K Insurance Limited, despite the near-identical name, appear as distinct rows in this analysis.
What might be driving the fall, and what remains interpretation
The supplied data allows us to establish three facts with confidence: decision volume for insurance providers has fallen sharply in the most recent quarter compared with the one before it; the uphold rate has fallen alongside it; and both movements sit within a longer downward drift visible since the second half of 2024. What the data does not establish is why. A falling uphold rate could reflect firms handling claims more carefully, the Ombudsman applying its published guidance more consistently to a particular type of dispute, changes in which types of complaint are reaching a decision, or simply the effect of a smaller sample drawing from a different mix of firms and case types. Veste's data cannot distinguish between these explanations, and readers should not treat the correlation between falling volume and falling uphold rate as proof that one caused the other.
Related categories offer some further texture without resolving the question. Motor insurance claim handling disputes carry a 32.3% uphold rate across 12,418 decisions, home insurance claim disputes sit at 38.3% across 24,388 decisions, and travel and life insurance claim disputes sit at 29.3% across 17,169 decisions. These are all higher than the current 90-day insurance provider rate of 24.5%, which suggests the recent fall is not simply a reflection of one particular claim type dominating the category, though the supplied data does not break the 90-day window down by claim type.
Individual decisions as illustration
Four recent decisions from the supplied dataset, all dated 2026-06-29, illustrate the range of outcomes rather than any statistical pattern. A complaint against Astrenska Insurance Limited over a declined personal accident claim was not upheld, with the ombudsman finding new medical evidence did not establish the claimant's injuries resulted solely from the accident in question, given documented prior incidents. A complaint against Advantage Insurance Company Limited over storm damage to a conservatory was not upheld after weather data showed snowfall of 3 to 5cm, well below the policy's 30cm threshold for a snow storm, with pre-existing deterioration identified as the likely cause of damage. A complaint against ReAssure Limited concerning pension tax-year reporting was not upheld on the substantive tax point, but the ombudsman found the firm had given misleading assurances about amending a P45 and ordered £500 compensation for the resulting distress. A complaint against Calpe Insurance Company Limited was partially upheld: the £3,000 excess itself was correctly applied under the policy, but a two-year gap in communication about claim progress led to a £150 compensation award. These four cases show the range of reasoning the Ombudsman applies, from policy definition disputes to service standard failures, but four decisions cannot support conclusions about the wider 90-day trend.
What the data does and does not tell us
The data confirms a genuine and sizeable movement: a 5.8 percentage point fall in uphold rate alongside a 30.7% fall in decision volume across two 90-day windows, both meeting the minimum sample threshold. It also confirms this sits within a longer decline from the 38 to 40% monthly rates common in late 2024 down to the mid-20s seen through spring 2026. What it does not confirm is causation, whether at firm level or across the sector. Published Ombudsman decisions are a subset of all complaints made to firms, shaped by which cases firms and complainants choose to escalate and how quickly the Ombudsman publishes outcomes. A change in that publication pipeline, rather than a change in underlying complaint handling, could itself produce some of the pattern seen here.
The practical implication
For anyone tracking insurance sector complaint outcomes, the headline point is that the 90-day snapshot is consistent with, rather than a departure from, a trend that has been building since late 2024. Given the reduced volume behind the latest window, and the fact that the category blends firms with uphold rates ranging from 7.6% to 39.8%, a single quarter's category-wide percentage should be treated as one data point in a longer series rather than a verdict on the sector's current performance.
