National Timber Group in administration: supply risk notes for project teams
Reviewed by Tom Sullivan
First reported on The Construction Index
30 Second Briefing
National Timber Group, the UK’s largest independent timber distribution and processing group with 47 sites and 1,150 staff, has entered administration, with Alvarez & Marsal appointed on 26 November 2025 and an accelerated sale process launched. Administrators have made 561 immediate redundancies, closed 13 branches and mothballed some production facilities, while other depots continue trading under brands including Thornbridge, Arnold Laver, Rembrand Timber and Norclad. Contractors, joinery shops and house-builders reliant on NTG’s structural timber, sheet materials and engineered products face short‑term supply disruption and potential regional gaps in merchant coverage.
Technical Brief
- Appointment of Alvarez & Marsal as joint administrators formally occurred on 26th November 2025.
- Five legal entities within National Timber Group entered administration as a consolidated group restructuring event.
- The group was originally assembled by Cairngorm Capital from at least eight regional timber businesses.
- Acquired brands include Thornbridge, North Yorkshire Timber, Rembrand Timber, Orchard Timber, Hymor Timber, SV Timber, Norclad and Arnold Laver.
- Administration followed a defined pre-process, with notice of intention filed on 14th November 2025.
- Thirteen branches were shut immediately on appointment, indicating abrupt regional capacity removal from the supply chain.
- Some production facilities are mothballed rather than closed, preserving potential future processing capacity for a buyer.
- An accelerated sale process is targeting disposal of all or discrete parts of the group’s assets.
Our Take
Within the 75 Infrastructure stories in our database, timber distribution failures like National Timber Group’s in England and Scotland are rare compared with contractor insolvencies, suggesting downstream supply-chain fragility is becoming a more material risk for project delivery schedules.
For UK regional builders and civils contractors that relied on brands such as Arnold Laver, Rembrand Timber and Thornbridge, the closure of 13 branches is likely to tighten availability of specialist timber sections and lengthen lead times, which can force short-term redesigns or substitutions on live projects.
Given National Timber Group was assembled by Cairngorm Capital through multiple acquisitions from 2018, this administration highlights the integration and working-capital risks of roll‑up strategies in construction materials distribution, a point that may be scrutinised more closely in future M&A across our Infrastructure coverage.
