About
About Treun Roc
The name is Scots — treun, strong, and roc, rock. We are a UK contractor for fit-out and construction, appointed on JCT, design and build, and labour-only.
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.
We take commercial jobs across the South East, and further where the programme and the client make sense. The work is fit-out, build, design and build, maintenance, civils, labour only, and the system we run a job on.
We price in writing, run a programme, keep variations recorded, and hand over a health and safety file. Where we are principal contractor, CDM 2015 is part of the week: construction phase plan, induction, RAMS and welfare.
