Only 20 motorway services in the UK remain in the ownership of the Department for Transport and let on 50-year leases to private operating companies.
[1] The vast majority of motorway services in the UK are owned by one of three companies: Moto, Welcome Break and Roadchef and a developing chain of stations being constructed by Extra.
Some of the 94 service areas on this list are on major A-roads rather than motorways.
These share the defining properties of motorway service areas, being named service areas operated by a single company with a range of facilities including food & drink providers, toilet facilities and vehicle servicing facilities.
Such service areas are rare on most A-roads, where basic filling stations with a single shop are more common.
