Mrs Pattison became Epsom’s first female head in September 2022 after six years as headteacher of Croydon High School in south London.

Boarding students at the college pay more than £42,000 a year and its alumni include Conservative MP Sir Michael Fallon, broadcaster Jeremy Vine and comedian Tim Vine.

Over 850 boys and girls attend the school, which was founded in 1853, and its acting head has been listed as Paul Williams.

Mrs Pattison’s husband George was a chartered accountant who was director of a management consultancy firm called Tanglewood 2016, according to Companies House.
