The Sadler's Wells Opera was renamed the English National Opera in November 1974, after relocating from Sadler's Wells. And so Sadler's Wells Orchestra also changed its name, to The English National Opera Orchestra.

It is the orchestra of the English National Opera (ENO), the opera company based in London and headquartered at the London Coliseum in St. Martin's Lane. It is one of the two principal opera companies in London. ENO's productions are sung in English.
