Nonetheless, the insurer reported pre-tax profits of £286.7m, rising 30% against the £220.2m reported the year before.
This was primarily the result of “strong” prior year reserve releases in the UK and internationally, as well as some non-recurrence of negative items in 2019, including the £33m Ogden discount rate impact.
In addition, customer numbers in the period were 6% higher at 7.17 million, up from 6.74 million the year before.

Whilst the division also recorded a 7% reduction in turnover to £1.25bn, customer numbers grew from 5.32 million to 5.58 million.
UK Household profit improved rose from £4.2m to £5.5m, despite bad weather which impacted the current period by around £5.3m.

Our response to that pandemic highlighted two of Admiral’s key strengths – competent execution in the short term and sustainable values for the long term.
“This year’s interims benefit again from our consistently competent underwriting and conservative reserving on past years, feeding into another strong set of results in the core business and beyond.”
