All indicators and reporting details

Peer averages are unweighted and exclude this company. Same-category firms may differ in business mix. Raw counts and upheld rates are context only, not quality ratings.

Contextual complaint rate

Complaints per 1,000 accounts or policies. Lower can be favourable only when compared with a genuinely similar business.

63,947

A raw count. Larger businesses commonly receive more complaints, so this is not a ranking measure.

FCA reported

Complaints closed

65,216

A raw count of complaints closed during the period. It may include complaints opened earlier.

FCA reported

Closed within 3 days

51.27%

The share closed within three days. Higher is generally favourable, subject to reporting scope.

Closed within 8 weeks

99.68%

Behind Your Money calculation adding the FCA's two published closure bands.

Closed after 3 days but within 8 weeks

48.41%
