What Flat Iron does

Flat Iron operates a UK-based full-service steak restaurant chain built around a single signature dish: the flat iron steak cut from the featherblade, priced at £15 and prepared using traditional European seam butchery. Founded in 2012 by Charlie Carroll from a pop-up above the Owl and Pussycat pub in Shoreditch, the company opened its first permanent site in Soho and has since grown to 17 London restaurants plus regional locations in Brighton, Bristol, Cambridge, Leeds, Manchester and Newcastle. Three further sites are confirmed for Birmingham (late 2026), Liverpool and Glasgow (2027), with restaurants typically located in character-rich, often Grade II-listed buildings in prime high-street locations.

The core offering is anchored on a proprietary butchery approach: whole-carcass seam butchery is practised in-house at the Covent Garden location by master butcher Scott and apprentice Jorge, and the company owns the Flat Iron herd of cattle in Thirsk, North Yorkshire in partnership with third-generation farmer Charles Ashbridge, supplying British native breeds plus a Wagyu suckler herd for premium specials. Ancillary revenue streams include a chain-wide gift card programme (sold via shop.flatironsteak.co.uk and valid for 12 months), branded merchandise (cleavers and whisky flasks), and the Flat Iron Fund/Trust charitable mechanism (10p per steak matched by Flat Iron to registered charity 1178402). Reservation infrastructure is provided by Dojo (Walkup) and the customer base is broad-based (general consumers, families, and special-occasion diners), with kids' menus available at specific sites.

Revenue is generated primarily through dine-in transactions across the directly-operated estate — averaging £15 for the signature flat iron steak, £20 for a 35-day aged ribeye, £24 for the Wagyu steak of the day, and £4.50-£7.00 for drinks. The business remains privately held as Flat Iron Steak Limited (England registration No. 08177784) with no disclosed parent company, subsidiaries or M&A activity; institutional investors include Piper Private Equity (2017, $12.17M) and TriSpan LLP (August 2025). Operational credentials include the Sustainable Restaurant Association's maximum three-star rating awarded in January 2024 and The Times Best Places to Work 2025.
