- Aviva shares rise as insurer flags UK regulatory clearance on Direct Line capital model
- Company says change should lift 2025 solvency ratio by about 2 percentage points, adding around £0.1 bln of capital synergies
- Investors now look to Aviva’s March full-year results for finalised impacts and next steps
Aviva (AV.L) shares rose on Tuesday after the insurer said UK regulators had approved a change to Direct Line’s capital model under Solvency II rules. The stock was up about 0.5% at roughly 690.6 pence by 1043 GMT, based on delayed pricing published by the company. 1
The move matters because insurers are judged on solvency — how much capital they hold versus regulatory requirements — and small shifts can change the room they have for dividends and other shareholder distributions. It also offers an early balance-sheet read-through from Aviva’s ongoing integration of motor and home insurer Direct Line.
Aviva said the Prudential Regulation Authority approved its request to revoke Direct Line’s Solvency II partial internal model, moving the business to the standard formula from Dec. 31, 2025. Aviva estimated the change would deliver around £0.1 billion of capital synergies at year-end and add about two percentage points to its full-year 2025 group shareholder solvency ratio, with more detail due alongside results in early March. 2
Solvency II is the insurance capital regime used in the UK and Europe, and an internal model is a regulator-approved method insurers use to calculate capital needs. Aviva said the shift to the standard formula would allow it to recognise diversification benefits between Direct Line and the wider group that had not been reflected in its group capital requirement.
The company said Direct Line can now be included in Aviva’s group Solvency Capital Requirement, the regulatory measure of how much capital an insurer needs to hold against risk. Aviva also reiterated it is working to move Direct Line’s business onto Aviva’s internal model in due course, subject to further PRA approval.
Aviva’s shares have climbed sharply over the past year and are trading not far from a 52-week high of 698.4 pence, with the stock closing at 687.0 pence in the prior session, according to Hargreaves Lansdown data. 3
For traders, the immediate question is how much of the estimated capital uplift turns into durable headroom once year-end numbers are finalised. In insurance, solvency ratios can be sensitive to market moves as well as claims experience, which can change the picture quickly.
But there are clear risks around delivery. The capital benefit is still an estimate, and delays to further regulatory approvals or higher-than-expected integration costs could reduce the buffer the market expects, especially if claims volatility picks up in UK motor and home lines.
