What SJG Group does

SJG Group (legal entity: SJG Temporary Works Ltd) is a UK independent consultancy specialising in Temporary Works for the construction and civil engineering sector. Founded in 2012 by CEO Simon Goldsmith BSc ICIOB, the firm provides four core service lines: Design Services (project-specific and standard detail temporary works designs covering scaffolding, formwork, falsework, crane bases, needling and propping, facade retention, and excavation support); Training Courses (Temporary Works Co-ordinator, Supervisor, and Awareness programmes plus health and safety courses delivered in partnership with Bridge Safety and Training); Site Support (provision of Temporary Works Co-ordinators, site auditing, and on-site technical assessments); and Contract Support (BS5975 procedural control, Competent Persons Logs, scaffold scheduling, expert witness, and tender advice). The underlying technology stack is AutoCAD and Tedds for structural design and analysis, supplemented by reusable Standard Detail Design Certificates and in-house CAT-3 independent design check packages. The firm operates from a York headquarters with regional offices in London, Glasgow, and Belfast, serving clients across England, Scotland, Northern Ireland and Wales.

The business is a professional services consultancy monetised through project-specific fees, retainer/service agreements with major contractors, on-site engineer placements, and per-delegate training course fees. Pricing is quote-based and not publicly disclosed; contracts are typically multi-year for senior engineering and design packages. Go-to-market is sales-led and enterprise-focused: SJG positions itself as the external 'internal Temporary Works department' for large UK principal contractors, with named enterprise clients including Berkeley Group (St Edwards), Nestlé (Tutbury factory), Denon Construction, Deanfield Homes, and Apollo Cradles. The company is privately held, founder-led, and bootstrapped — no external funding rounds, M&A, or institutional investors are disclosed. Operations are reinforced by ISO 9001:2015, ISO 45001:2018, Constructionline Gold, and CPD UK accreditations, and the firm runs apprentice and graduate schemes to develop engineering and commercial talent internally.

• CPC Project Services: UK construction consultancy providing project management, contract support, and Temporary Works coordination services. Direct peer — competes on procedural, planning, and TWC/TWS support work alongside design services.
• Mabey Hire: UK provider of temporary works equipment hire, design, and installation including propping, shoring, and scaffolding. Direct peer — competes for the same principal contractor clients on Temporary Works design and site support, with overlapping BS5975 compliance positioning.

Broad incumbents

• Arup: Global engineering consultancy with Temporary Works and construction phase design capability in the UK. Broad incumbent — competes at the high end on complex Category 3 design checks and major project TW consulting where clients seek a large-firm delivery vehicle.
• Doka UK: International formwork manufacturer offering Temporary Works engineering, planning, and site support to UK contractors. Broad incumbent — overlaps on formwork and falsework design but anchored to proprietary formwork systems.
• PERI UK: Global formwork and scaffolding manufacturer with a UK engineering services arm providing Temporary Works design. Broad incumbent — overlaps on formwork/falsework design and on-site TW engineering, with the advantage of proprietary product tie-ins.
• BrandSafway (Hünnebeck): Global scaffolding and access services provider with formwork, shoring, and Temporary Works engineering capability across the UK. Broad incumbent — competes on scaffolding TW design and site engineering, though positioned as a manufacturer-renter rather than independent consultancy.

Emerging players

• Heath & Safety Executive (HSE) trained providers — e.g. CITB / Build UK affiliated TW trainers: CITB and affiliated training organisations deliver TWC/TWS courses in the UK, partially overlapping with SJG's training revenue stream. Emerging player — competes primarily on training course delivery rather than full-service TW consultancy, but represents a competitive alternative for the training revenue line.
