Which is the most popular fast food chain in the UK?
McDonald's ranks #1 with approximately 12M actively engaged UK consumers.
How is fast food popularity measured?
We measure engagement through anonymized UK search-behaviour signals — searches for the brand, nearby branches, menus, meal deals and delivery over the trailing 12 months.
Does delivery through Deliveroo, Just Eat or Uber Eats count?
Searches naming the chain alongside a delivery service count towards that chain's audience. The aggregator platforms themselves are separate audiences and are not included in this ranking.
Are British chains included alongside American ones?
Yes. Greggs, Wimpy and other UK-founded chains are measured on exactly the same metric as McDonald's, KFC, Burger King and Subway.
How often is the ranking updated?
Weekly. Menu launches, price promotions and viral campaigns can shift positions noticeably.
