The Police Treatment Centres is a registered charity supported by voluntary donations from serving police officers primarily in the northern forces of England and Wales, Scotland and Northern Ireland, but also from British Transport Police, the Civil Nuclear Constabulary and the Ministry of Defence Police. Officers currently make a donation of £1.30 per week from their pay. The charity provides two Treatment Centres where serving and retired police officers can receive rest, recuperation and treatment following an illness or injury with the aim of assisting their return to better health. The Centres are St Andrews, in Harrogate, North Yorkshire, and Castlebrae in Auchterarder, Perthshire. Almost 4000 serving and retired officers attend the Treatment Centres each year and most receive intensive physiotherapy. Others seek support with stress-related conditions and some attend for reasons of respite or to recuperate following an illness or operation.
