About
A contractor. Not a brochure.
Treun Roc is a young company. The name is Scots: treun — strong — and roc — rock. The work is construction, run as a contractor.
Who we are
TREUN ROC CONTRACTS LTD was incorporated on 14 August 2025 and is registered in England and Wales, number 16649937. The director is Ryan Wilson. The registered office is in Watford.
The company is young. The work is construction: fit-out, build, design and build, maintenance, civils, labour only, and the digital system we run a job on. We take commercial jobs across the South East, and further where the programme and the client make sense.
We price in the open, run a programme, keep variations in writing, and hand over a file — not a pile. Where we are principal contractor, CDM 2015 is a live system on the job.

On site
The job is the programme.
We price in the open, run a programme of works, keep variations in writing, and hand over a file — not a pile. Where we are principal contractor, CDM 2015 is a live system: construction phase plan, induction, RAMS, welfare, and a health and safety file at the end.
Public liability and professional indemnity insurance are in place. JCT, design and build, and labour-only are how we are appointed — not slogans on a capabilities slide.
Lines of work
- Fit-OutShopfit, convenience expansions and commercial interiors that open on the date that was promised.
- BuildCommercial building work — strip-out, structure, envelope and rebuild — including fire reinstatement.
- Design and BuildOne contract from agreed design through to handover. We hold the contractor risk.
- MaintenanceFabric, decoration and small works that keep a building usable — planned and reactive.
- CivilsThe groundworks, drainage, slabs and external works that sit under a commercial job.
- Labour OnlyNamed trades supplied onto another contractor’s programme, supervised to the same standard as our own jobs.
- TechnologyThe digital system we run every job on — and the specialist technology packages a fit-out actually needs.
Straight answers
- How are you appointed?
- JCT and similar building forms, design and build, or labour only. The form is written down before the work starts.
- Where do you work?
- South East England as a rule. Further, where the programme and the client make sense — Hexham is on the books for that reason.
- Do you act as principal contractor?
- Yes, where the job requires it. CDM 2015 is then a live system: construction phase plan, induction, RAMS, welfare, and a health and safety file at handover.
- Is insurance in place?
- Public liability and professional indemnity. We will send the current schedule when a job is being priced.
- How do we start?
