Frequently Asked Questions
Where does the insurers complaint data come from?
All data comes from official UK regulators — the FCA (banks and insurers), Ofgem (energy suppliers), and Ofcom (broadband providers). These bodies require companies to publish complaint statistics at regular intervals. We process their public datasets and calculate complaint rates to enable fair comparisons.
What does complaint rate mean?
Complaint rate is the number of complaints per per 1,000 policies. This normalises for company size — a large company with millions of customers will naturally receive more total complaints than a small one. By using a rate, you can compare fairly across companies of different sizes.
How often is this data updated?
Regulator data is published quarterly or twice yearly depending on the sector. We update our rankings whenever new official data is released. Each company page shows the period covered by the data.
Does a high complaint rate mean a company is bad?
A high complaint rate is a significant red flag, but context matters. Some companies serve higher-risk customer segments or product types that attract more disputes. We recommend also checking the Ombudsman uphold rate — this shows how often customers who escalate complaints actually win their case, which is a strong indicator of whether complaints are justified.
