What One.site does

One.site is a UK-based software-as-a-service company providing digital workforce management for the construction industry, with primary focus on UK housebuilders. The platform digitizes site inductions, sign-in processes, qualification verification, and compliance tracking through eight integrated modules: Remote Inductions, Site Access Management, Site Reporting, Qualification Management, Observation Reporting, Facial Recognition, Digital Signage, and Red & Yellow Card Management. Notable technical components include CSCS (Construction Skills Certification Scheme) card verification integrated with worker profiles, multi-method sign-in (kiosk PIN, QR code scanning, and facial recognition), QR-based observation reporting that requires no app downloads, and a CSCS Smart Check feature for instant on-site card verification. The platform is accessed via web browser with mobile-first design, and an API is offered for integration with customers' existing systems.

The company originated from sister company UK Connect, which spent approximately a decade installing broadband on construction sites, providing the domain expertise that informed One.site's product design. The platform pivoted during the Covid-19 pandemic in 2020 to add contactless tools including Covid Test Tracking. One.site is headquartered in Farnborough, UK, employs 11-50 people, and operates as a privately held entity with the One.site trademark registered in the name of Paul Farr and licensed to UK Connect. Mitchell Smith was appointed Managing Director in July 2024.

Revenue is generated through per-site subscription licensing at £99 per site per month (annual billing, equating to £1,188 per site per year) with a 20% discount versus monthly billing, no limits on operatives or inductions, and a 4-week free trial including setup, configuration, and training. Go-to-market is hybrid: sales-led for enterprise customers via demo booking, combined with product-led self-serve trial onboarding. The primary customer segment is UK housebuilders with multiple sites and up to around £100m in revenue, including enterprise accounts such as Lovell (part of Morgan Sindall Group), Cala Homes, and Crest Nicholson, alongside mid-market customers including KIWI Homes, Bancon Homes, and Bewley Homes. Key buyer personas are Health & Safety Managers, Construction Directors, and Operations Directors. Distribution includes direct sales, self-serve trial, and a referral channel via sister company UK Connect. The platform reports 500+ active sites, 100k+ inducted workers, and a 98% customer retention rate.

Expansion highlights5 records

Broad incumbents

• Procore: Comprehensive construction project management platform with broad workforce and safety modules. Competes for site compliance workflow ownership within large enterprise accounts rather than as a specialist point solution.
• Autodesk Construction Cloud: Broad construction technology suite that includes workforce, safety, and qualification management features. Competes as part of a wider BIM and project management portfolio rather than as a specialist site induction platform.

Direct peers

• Avetta: Global contractor pre-qualification and qualification management platform serving industrial and construction clients. Comparable to One.site's qualification management and CSCS-style verification, particularly for larger enterprise and supply-chain compliance.
• SafetyCulture: Mobile inspection and observation reporting platform widely deployed on construction sites worldwide. Overlaps directly with One.site's observation reporting and site safety workflows, making it a close point-solution competitor for site compliance.
• HammerTech: Construction site management software with worker onboarding, induction, and qualification tracking features comparable to One.site's core modules. Targets a similar mid-market and enterprise construction customer base.
• ISNetworld: Contractor management and qualification verification platform widely used in industrial and construction settings. Comparable to One.site's pre-qualification and ongoing worker verification functionality, especially for contractor onboarding.
• Skillcast: UK compliance and e-learning platform with induction and training modules for regulated industries. Directly comparable to One.site for compliance training and induction workflows, particularly with UK-based regulated employers.
• iHASCO: UK-based provider of health & safety e-learning and induction training content for construction and other regulated sectors. Directly competes for the remote induction and compliance training budget One.site targets.
