The firm, which employs 2,000 people in York and 1,300 in Sheffield, revealed new business rose by 25 per cent to £823m over the period, notching up its eleventh straight quarter of growth.
Aviva snapped up Friends Life for £5.6bn in April, sealing the industry’s biggest merger since 2000 and creating a group comprising 31,500 employees.
The firm said it has so far achieved £91m of savings from the merger as part of its plans to make £225m of annual savings from the deal by the end of 2017. It added its savings programme was ahead of schedule.
Earlier in the year it revealed it expects to slash 1,500 jobs, almost five per cent of its workforce, as it cuts a third of its offices.
Chief executive Mark Wilson said: “The acquisition of Friends Life is everything we expected it to be.
“At the same time our UK life business continues to grow and our customers are responding positively to the full range of pensions freedoms we offer.”
The industry had been left reeling by the annuity reforms, which took the insurance industry by surprise when they were announced by Chancellor George Osborne in last year’s March Budget.
However, analysts said Aviva is boosting its life insurance unit and offering a range a pensions options to bridge the shortfall in annuity take up across the industry.
