Esure Group plc is an Internet and telephone-based insurance company based in Reigate, Surrey, England. It also has offices in Manchester and Glasgow. The company was listed on the London Stock Exchange until it was acquired by Bain Capital in December 2018.

Esure was founded in 2000 by businessman Peter Wood, who also launched the Direct Line insurance company for the Royal Bank of Scotland. In 2005 Peter Wood also launched the highly successful insurance brand “Sheilas’ Wheels”. The brand is characterised by its three pink sequin-clad Sheilas who starred in a series of adverts made for the brand alongside a pink ‘Sheilamobile’. The brand became one of the fastest-selling insurance brands in the UK. Sheilas’ Wheels focuses on women drivers but has offered cover to men too from its launch. The product includes benefits such as an enhanced bag cover.

Esure is also known for its high-profile commercials with Michael Winner, used from 2002 to 2005 and resuming in 2007. The adverts spawned the phrase, “Calm down dear, it’s a commercial”.
