How It Works

Official Data

We collect complaint statistics from the FCA, Ofgem, Ofcom and the Financial Ombudsman Service — the same bodies that regulate these companies.

Fair Comparisons

Raw complaint numbers favour larger companies. We calculate rates per 1,000 customers so you can compare fairly, regardless of company size.

Plain English

Regulator data is buried in spreadsheets. We turn it into simple scorecards with trends, comparisons and clear ratings for every brand.
