Warnborough College UK provides educational programmes both on-site in Canterbury, England, and by distance learning.

Warnborough College has been the subject of multiple controversies relating to misrepresentation, education quality, legal and tax troubles, and eligibility to participate in government financial assistance.

[7] In 1995, Warnborough College Oxford enrolled its first group of students onsite in a four-year US academic programme, which created significant controversy and litigation that led to its closure and liquidation the following year.

It offered graduate and undergraduate residential and non-residential degrees in liberal arts, scientific and professional studies.

[12] Warnborough represented to the US Department of Education during its termination hearings in 1996 that, at the time, its degrees were actually issued by the controversial and unaccredited Greenwich University (Norfolk Island), with which it had a contractual arrangement to do so.

The Boars Hill facilities were used for teaching, administration and accommodations,[22] and were characterized by the Financial Times as "a grotty campus on the outskirts of town".

In February 2008, Sean O'Foghlu, chief executive of NQAI told the Irish Independent that because Warnborough College is not a recognised higher education institution or awarding body the qualifications are "effectively worthless".

[33] The Oregon Office of Degree Authorization named Warnborough in its former list of unaccredited universities, with its then administrator, Alan Contreras, characterising Warnborough College as "a diploma mill that has managed to move back and forth between Britain and Ireland for decades without either government's being able to put an end to it.

In the aftermath of the BBC report, enrollment declined drastically, creating a financial crisis because Warnborough had taken out a $2 million high-interest loan, which could only be paid off by recruiting more students.

[36] When students discovered that Warnborough had no connection with Oxford University about fifteen or twenty of them - roughly half the new enrollment, immediately withdrew from the college with some intending to sue for refunds.

[22][36] The lawsuit resulted in a judgement against Warnborough College by the Superior Court of King County, Washington of nearly $300,000.

[2] In 1996, Warnborough relocated temporarily to offices rented from the New Road Baptist Church in central Oxford.
