Rigg Construction (southern) Limited

What Rigg Construction (southern) Limited does

Rigg Construction (Southern) Limited is a privately held UK main contractor founded in 1989 and headquartered in Melksham, Wiltshire. The firm delivers a portfolio of five integrated construction service lines — new build, design and build, refurbishment and modernisation, project management (covering construction management and management contracting), and partnering — under contractual arrangements that include tender, partnering, negotiation, traditional, design and build, and framework agreements. Project scope spans new educational establishments, residential and care home developments, heritage and listed-building refurbishments, commercial showrooms and retail fit-outs, healthcare facilities, and military and community buildings, with documented individual project values in the £0.7 million to £3.2 million range.

The firm's customer base is anchored in Southwest England, covering Wiltshire, Somerset, Gloucestershire, Dorset, Berkshire, and Hampshire. Public sector and institutional clients — Wiltshire Council, Swindon Borough Council, NHS Wiltshire, the Ministry of Defence, Avon Fire and Rescue, and multiple schools and colleges — are complemented by private commercial clients including Canada Life, Ropemaker Properties, Majesticare, Herman Miller, Rygor Commercials, and the Wiltshire Air Ambulance Charitable Trust. The company employs approximately 40 permanent staff, including qualified contract and site managers, skilled operatives, and a head office team, all with CITB Health and Safety qualifications and DBS checks for sensitive sites.

Rigg Construction holds a defensive certification stack that includes ISO 9001 (since March 2010), ISO 14001 (since March 2007), CHAS principal contractor status (since 2011), Constructionline, NHBC, and SafeContractor. These accreditations are operational prerequisites for bidding on UK public sector frameworks and represent the firm's primary competitive moat alongside 34 years of regional brand reputation. Revenue is project-based, derived from one-off construction contracts rather than recurring SaaS-style streams, with pricing delivered through project-specific quotations rather than published rates. Distribution is direct-to-client through tender processes, partnering arrangements, and negotiated contracts, supported by a website portfolio and a LinkedIn presence.
