Carillion plc is a leading support services company, with a substantial portfolio of Public Private Partnership projects and extensive construction capabilities.
When Carillion was launched as an independent listed company in July 1999, following the demerger from Tarmac plc, we were predominantly a UK construction company. Today, we are a leading UK support services company, having transformed our business through implementing our consistent and successful strategy.

We operate in the UK, the Middle East and North Africa (MENA), Canada and the Caribbean. Our head office is in Wolverhampton, UK.

We seek to embed sustainability into all our operations, and this is reflected in our core values. The services we deliver contribute significant benefits to society, as well as providing employment for around 46,000 people.
