MSC officers receive no payment for duties they perform. However, they receive a subsistence allowance throughout their service, and during training can claim back costs for travel expenses, as well as additional expenses such as the cost of purchasing boots and a torch, which are not issued with uniform in the Metropolitan Police. Once they pass out of training and receive their Warrant Card, Special Constables are afforded free travel both on and off duty on the London Underground, Docklands Light Railway, London Buses the Croydon Tramlink, London Overground and TfL Rail with a Police Oyster Card by virtue of arrangements with Transport for London.
