The West Midlands Ambulance Service University NHS Foundation Trust (WMAS UNHSFT) provides a 999 emergency medical response service for the counties of Herefordshire, Shropshire, Staffordshire, Warwickshire, Worcestershire, the seven boroughs of the West Midlands metropolitan county and combined authority area: Birmingham, Coventry, Dudley, Sandwell, Solihull, Walsall and Wolverhampton, and the unitary authorities of Stoke-on-Trent and Telford & Wrekin.

The trust also provides non-emergency patient transport services in Birmingham, the Black Country, Arden, Cheshire and the Wirral.

The contract for Worcestershire, which had been run by the ambulance service for 30 years, ended in March 2020 when it lost out to a private provider.

It is the best-performing English ambulance service in the NHS, being graded Outstanding by Care Quality Commission (CQC) inspectors in January 2017 and 2019.

The trust said it lost out because it "refused to compromise on patient safety", and was not prepared to outbid the offer of E-Zec Medical Transport.

[10] In the 2017/18 contract negotiations with clinical commissioning groups (CCG), where Sandwell and West Birmingham CCG negotiated on behalf of all the West Midlands CCGs the trust sought financial compensation for the delays to ambulances caused by patient handover delays at local hospitals.

These callers will be diverted to other sources of help, such as community-based rapid intervention services, or attempts will be made to resolve the issue on the phone.

This resulted in five centres spread across the region operating independently using varying levels of technology at sites:[18] Millennium Point, Brierley Hill; Stone Road, Stafford; Abbey Foregate, Shrewsbury; Bransford, Worcester and Dale St, Leamington Spa.

operates two EOCs based at Millenium Point, Brierley Hill (Trust HQ) and Tollgate Drive, Stafford.
