What Rullion Engineering does

Rullion Limited is a privately held UK workforce solutions provider founded in 1978 by Themis Saoulli, operating as the parent of The Rullion Group alongside three wholly-owned subsidiaries: Rullion Build Ltd (construction recruitment), Rullion Engineering Ltd (engineering recruitment), and Rullion IT Plus Ltd (IT recruitment). Headquartered in Altrincham, Cheshire, the company self-describes as the UK's largest workforce solutions provider in critical infrastructure, serving enterprise clients across rail, utilities, energy, nuclear, manufacturing, construction, retail, and financial services. Its portfolio spans Managed Service Provider (MSP) and Recruitment Process Outsourcing (RPO) programmes, executive search, permanent and temporary recruitment, Train to Deploy (TTD) skills development, Early Careers pipelines, background screening, embedded resource, and Statement of Work (SoW) project delivery. The company manages over £300 million of recruitment spend annually on behalf of clients and fills approximately 5,000 permanent, contract, and temporary positions each year, with 138 live jobs currently advertised.

The service is human-capital intensive and does not rely on proprietary technology products. Rullion supplements its delivery model with third-party integrations — notably Konfir for secure employment and income verification, and Microsoft Forms for confidential reporting — and operates its own job board and sector-specific web pages for candidate acquisition. Named enterprise customers include Siemens, EDF Energy, E.ON, Alstom, Hitachi, Stadler, UK Atomic Energy Authority, URENCO, Northumbrian Water, KAEFER, Balfour Beatty, Co-Op, Close Brothers, and Hanson, evidencing a diversified but enterprise-anchored client base.

Rullion's go-to-market is sales-led, built on direct enterprise field sales and long-term contractual relationships in regulated sectors. Pricing is quote-based and individually negotiated: permanent placement fees typically range from 8-15% of annual candidate salary, while MSP and RPO engagements are structured as management fees or mark-up on contractor rates under multi-year contracts. The company operates primarily in the UK with an explicit European footprint expansion evidenced by a dedicated "Find us in Europe" section on its website. Ownership remains private and appears concentrated with the founding family/management; no external private equity, venture capital, or public shareholders are evidenced.
