Aviva has pointed to pet insurance, Green Flag breakdown cover and small business policies as the part of its enlarged general insurance business with the most room to grow, arguing that its market share across these specialty personal lines sits at just 6% to 7%, against more than 20% for its core motor and home books.
Speaking after Aviva published its half-year 2026 results on 14 August, UK and Ireland general insurance chief executive Jason Storah made the case that this is the corner of the business built by the Direct Line acquisition where Aviva has the furthest to go before it catches up with its position elsewhere.
It's a different emphasis to how the Direct Line deal has mostly been discussed since completion in July 2025, when coverage centred on motor and home - the two lines that make Direct Line, Churchill and Green Flag household names - and on the leadership reshuffle that followed. Storah's pitch is that the smaller product lines sitting inside the same group are where the unclaimed territory actually is.
Aviva's UK and Ireland general insurance arm booked gross written premium of £5.91bn in the first six months of 2026, up 42% on the £4.14bn recorded in the same period last year, largely a function of Direct Line now sitting inside the group's books. Operating profit in that division rose 50% to £643m. Group-wide, general insurance operating profit climbed to £905m from £648m.
Those figures sit within a broader set of results that saw Aviva's total operating profit rise 24% to £1.32bn, even as statutory IFRS profit fell to £418m - a reminder that the "operating profit" measure insurers favour and the bottom-line profit reported under accounting rules can move in very different directions in the same period. UK personal lines premiums specifically - the Direct Line-heavy part of the book - very nearly doubled, up 98% to £3.68bn.
Cost synergies from the deal, according to Storah, have reached roughly £100m so far, with management guiding toward £130m by the end of 2026 and further gains expected to flow through into 2027 and beyond.
Storah's argument centres on a gap between Aviva's customer base and what it actually sells them. Speaking to Insurance Times, he pointed out that Aviva counts around 22 million customers in the UK, many of whom already own pet insurance - just not with Aviva, which has "never sold any of them pet insurance" historically. He made a similar point about Green Flag breakdown cover and Direct Line for Business.
To illustrate the scale of the prize, Storah noted that the specialty personal lines market is roughly the same size as the UK property insurance market - a way of framing how much room he believes is left, even before any further growth in the core motor and home business.
Whether that gap closes as quickly as Aviva hopes is a separate question from whether it exists. Cross-selling into an existing customer base is a strategy most large insurers have tried with mixed results, and pet insurance in particular is a market with its own entrenched claims-cost problem. According to the Association of British Insurers, member insurers paid out more than £1.23bn in pet claims during 2024, up 4% on the year before, as vet fee inflation continued to run well ahead of general prices. Roughly 4.6 million UK pet owners held cover that year - a record, but still thought to represent only a minority of the country's pet-owning households, leaving plenty of room for growth but also plenty of pricing risk for any insurer chasing share in the category.
Storah also gave an update on the mechanics of stitching the two businesses together. Claims, customer service and operations teams have now been unified under single leaders spanning both the Aviva and Direct Line brands, he said, and the group has consolidated its view of which suppliers and outsourcing partners it works with across the combined business.
That doesn't mean the job is finished, though: Storah said four further phases of integration remain, a process he expects to run through to 2028. Separately, Aviva has previously flagged that a full re-platforming of Direct Line's claims systems is the single largest piece of work still outstanding, with more of that job left to do than has been completed so far.
For brokers and rivals watching, this results season says less about whether Aviva can bed in a £3.7bn deal - the synergy numbers suggest that part is broadly on track - and more about where it points the combined business next. Pet bowls and breakdown trucks, it seems, will get just as much boardroom attention as motor and home.
