Each service carries its official gov.uk page, the online startUrl, the page's last update date, figures (fee, processing time as stated, eligibility and required documents — each with value, unit, the quoted sentence and its source URL), and a dated list of changes since 2025 (passport fees from 8 April 2026, the ETA fee and enforcement, the BRP → eVisa switch, the end of the Universal Credit 2-child limit, Making Tax Digital for Income Tax). Common names resolve as aliases (passport → passport-renewal-adult, brp → evisa, sorn → vehicle-tax-sorn). No service returns the listing with the aliases; an unknown service answers covered:false with the nearest keys.",
