Recovery practice is broadly uniform across the UK because the same operational standard (PAS 43), the same lifting-equipment regime (LOLER, PUWER) and the same Road Traffic Act apply UK-wide. The differences are in council enforcement procedures, Low Emission Zone schemes, and the police force structure.
In England and Wales the abandoned-vehicle framework is the Refuse Disposal (Amenity) Act 1978. In Scotland the equivalent is the Civic Government (Scotland) Act 1982 sections 99 to 103. In Northern Ireland the Pollution Control and Local Government (NI) Order 1978 covers the same ground. The procedure is similar in all three: notice to keeper, statutory holding period, then disposal.
Clean Air Zone, Low Emission Zone and Ultra Low Emission Zone schemes are run by individual councils or city regions. London ULEZ, Birmingham CAZ, Bath CAZ, Bristol CAZ, Newcastle Tyneside CAZ, Sheffield CAZ, Portsmouth CAZ, Bradford CAZ, Oxford ZEZ, York CAZ all charge non-compliant vehicles entering the zone. The Scottish LEZ scheme operates in Aberdeen, Dundee, Edinburgh and Glasgow.
