James Donaldson & Sons

What James Donaldson & Sons does

James Donaldson & Sons, now trading as Donaldson Group, is a sixth-generation family-owned business founded in 1860 in Tayport, Scotland, specialising in the processing, manufacturing, merchanting, and distribution of timber and related construction products. The group operates a horizontally integrated portfolio of 11 businesses and 6 additional brands across 47 UK sites with over 1,700 colleagues, spanning timber frame manufacturing (Donaldson Timber Systems, Donaldson Timber Engineering), timber distribution and merchanting (MGM Timber, James Donaldson Timber, TimberCut4U), building materials (Smith & Frater, Donaldson Direct), insulation, doors, roofing fabrication (Nu-Style Products), and kitchens and interior products (MGM Kitchens, Optima Kitchens, Kitchens International, Stonecare, Rowan Manufacturing, Silktrim). The group has consolidated its position through six acquisitions between 2016 and 2021 and rebranded from James Donaldson & Sons to Donaldson Group in 2022 to reflect its evolution beyond its timber merchant origins.

The group's business model combines B2B trade supply — primarily to the UK construction industry via direct sales teams within each specialist business unit — with B2C retail distribution through MGM Timber's 10+ branches and dedicated kitchen showrooms. Revenue is generated predominantly through one-time hardware/product sales of timber, engineered timber frames, building components, kitchens, worktops, and roofing/cladding products, supplemented by timber cutting services and digital specification tools (Spec3D). Customer segmentation is horizontal, with no single anchor customer disclosed and a distributed base spanning construction trade professionals and retail consumers.

The group is led by Andrew Donaldson (CEO, 6th generation) and Michael Donaldson (Executive Chairman, 6th generation), following a 2020 leadership transition in which family members resumed control after the 2011–2020 tenure of Scott Cairns as the first non-family Group Managing Director.
