Following the news that Aviva’s GBP3.7 billion acquisition of Direct Line Insurance Group is set to finalize on or around 1 July 2025 after a High Court Sanction hearing and the firm expressing it will proceed with the deal ahead of receiving clearance from the Competition and Markets Authority (CMA);

Beatriz Benito, Lead Insurance Analyst at GlobalData, a leading data and analytics company, offers her view:

“Aviva is the largest general insurance player in the UK; accounting for 9.7% of GWP in 2023 as per GlobalData’s UK Top 25 General Insurance Competitor Analytics*. It has a healthy lead over Allianz and AXA—the joint-second-largest players which each control 7.6% of the market. Aviva’s position as the leading player will strengthen significantly upon the acquisition of Direct Line, with the combined group potentially almost doubling the joint-second-largest player’s market share (14.4%). In particular, the greatest advancements will be in the motor insurance space, where Aviva could end up controlling roughly a fifth of the market (19.6%). It would also command a significant share of the total UK property insurance market (17.3%).

“With Aviva expressing confidence that the takeover will go ahead, it is willing to proceed with the acquisition ahead of the CMA’s formal decision if the High Court Hearing sanction is favorable. This makes the High Court Sanction hearing a crucial date.

“Aviva’s decision not to wait to receive the CMA’s decision signals confidence that it will receive unconditional clearance, while also shows keen interest in expediting the deal. Unlike some jurisdictions, the UK’s merger control system is non-suspensory; implying that a transaction can be completed before the CMA gives the green light. However, this is not risk free as remedial measures would need to be taken if the CMA concluded that the scale of the combined group would result in a substantial lessening of competition in the market. If that were the case, the CMA could impose remedies (such as divestitures) to lessen the impact, which could be detrimental to Aviva’s reputation. Under the acquisition proposal, Direct Line’s brands, such as Churchill and Darwin Motor Insurance, will all now fall under Aviva’s umbrella.

“In any case, the resulting larger combined group could benefit from operational efficiencies, which may potentially reduce costs for Aviva and may result in more-favorable premium rates for customers. At the same time, having a dominant player in the market may end up reducing the number of major competitors; thereby limiting consumer choice. Meanwhile, the proposed merger has already had repercussions with top executives at Direct Line stepping down from their position and fears arising about potential job losses upon completion of the takeover.”
