Editorial Team
DealSifu comparisons are produced in-house: our researchers collect data from providers, government registers and official tariff sheets into a price database, and re-verify plan terms before anything is published.
How our editorial checks work
Researchers begin with a provider or government source, then separate prices, contract periods, coverage and restrictions into comparable fields. Before publication, we check the source link, calculations and meaning in both languages. We also retain verification dates when records change, so readers can see which version of the underlying information supports a comparison.
