Alpha Plus Group is an education group whose primary purpose is to develop excellence in education through well-directed investment and professional governance. It was acquired in December 2007 and is the second largest private education business in the UK, and the largest in London.
 
The Group comprises 19 independent educational establishments ranging from nurseries to sixth-form colleges, which are consistently ranked as excellent in inspections by ISI or Ofsted. These include Wetherby School, Pembridge Hall School, St Anthony's School for Boys, Chepstow House and the Abbey DLD Colleges.
 
The Gold Standard is Alpha Plus Group’s vision of educational excellence. It comprises two dimensions: a culture of high aspirations and expectations and an operationally robust governance process, through which schools and colleges are simultaneously supported and challenged.
 
In addition to organic expansion and relocation of existing institutions, 6 new schools have been established. These include two new openings in September 2017: Wetherby Kensington and Wetherby-Pembridge New York.
