[4][5] The Princess Michael of Kent Wing at the Shrodells site was opened by Princess Michael of Kent in 1986[6][7] and an acute admissions unit was opened by Andy Burnham, the Secretary of State for Health, in February 2010.

The hospital was designated "inadequate" in its 2015 CQC inspection, but was upgraded to "requires improvement" in January 2018.

Section 106 agreements which will provide £3 million for infrastructure around the Vicarage Road site, including education and transport, were signed on 26 March 2010.
