In March 2018, Endsleigh was acquired by A-Plan Holdings, and is the only official and approved insurer of National Union of Students.

In 1976 the NUS sold 100% of the company to Gouda Insurance International, as it was felt a stronger financial base was needed to fully exploit market opportunities.

In July 1995, Endsleigh's founder and still driving influence, Mike Naylor, was killed in a car crash in Southern France at the age of 59.

The company moved into the business market in 2000, and this combined with a 25% increase in customer base helped profits leap from £2.5m in 2000 to £8.6m in 2003.

In February 2005 the 'Sunday Times PricewaterhouseCoopers Profit Track 100' rated Endsleigh as the 76th fastest growing company in the UK, at 52% a year.
