A long-term investment in British forestry, British industry, and keeping UK timber viable

British sawmilling has been part of the UK’s industrial landscape for centuries.
Long before global supply chains and imported timber dominated the market, British sawmills helped build rural economies, supported woodland management, and supplied the timber used across construction, agriculture, mining, transport, and infrastructure throughout the country.
It was never an industry built around short-term thinking.
For generations, sawmills existed because forestry was seen as a long-term responsibility. Timber was treated as a managed crop. One that required planning, skill, investment, and patience. Forests were planted, knowing the people harvesting them might not even be born yet.
That way of thinking still matters today.
However, modern timber markets have undergone significant changes. The UK now imports most of the timber it uses, despite demand continuing to grow across construction, fencing, landscaping, manufacturing, biomass, and infrastructure. Cheap imports, global competition, and changing supply chains have placed huge pressure on British forestry and domestic sawmilling.
At the same time, people are asking bigger questions about where timber comes from, how forests are managed, and whether Britain still has the capability to process its own natural resources properly.
For SDL, investing in sawmilling was never just about adding another part to the business.
It was about backing an industry we believe still matters.
Not only for forestry, but for rural jobs, supply chain resilience, renewable energy, woodland management, and the long-term future of British timber itself.
Britain used to understand the value of timber
Britain’s forestry sector was shaped heavily by the First World War.
By the end of the conflict, the country had depleted much of its woodland resource and realised how vulnerable it had become by relying so heavily on imported timber. That led to the creation of the Forestry Commission in 1919 and a huge national effort to rebuild British forestry capacity over the decades that followed.
Forests were planted across the country. Rural infrastructure developed around them. Sawmills, haulage firms, harvesting contractors, and timber processors became part of local economies.
Forestry was treated as strategic.
Over time, imported timber became cheaper and easier to source at scale. Global supply chains expanded. Domestic sawmilling struggled to compete against lower-cost imports arriving from overseas. Though that shift did not happen overnight, the effects are still being felt today.
The UK remains one of the largest importers of timber in the world, despite having a growing demand and a productive forestry sector of its own.
For SDL, that raises an important question. If Britain stops investing in its own timber industry, what happens to the skills, infrastructure, machinery, and processing capability that forestry depends on?
Forestry depends on the industry around it. Without viable harvesting, haulage, processing, and end markets for British timber, long-term woodland management becomes much harder to sustain.
Forestry is not about clearing landscapes
A common misunderstanding around forestry is that harvesting automatically damages woodland, when in reality modern forestry is built around long-term management designed to keep forests productive, healthy, and sustainable over generations.
Trees are planted, thinned, harvested, replanted, and continuously managed as part of an ongoing cycle. Over the last century, British forestry has evolved significantly, too. Earlier approaches often focused heavily on timber production, whereas modern forestry also has to balance biodiversity, habitat management, conservation, disease control, public access, and long-term environmental resilience alongside commercial timber production.
However, forestry also needs to remain economically viable if long-term management is going to continue.
Without active markets for British timber, investment slows, infrastructure declines, and skills gradually disappear from the industry. In some cases, woodland can become neglected simply because there is no longer enough commercial return to support proper management over time.
That is one of the reasons SDL believes domestic processing still matters. Not only because Britain still needs timber, but because productive, well-managed forestry depends on having viable British businesses around it capable of harvesting, processing, transporting, and properly utilising the material grown here.

Why SDL built an integrated timber operation
Traditionally, timber supply chains could become fragmented very quickly.
Timber might pass through several different businesses between harvesting and final use. Material could sit at roadside waiting for transport. Lower-grade timber might lose value because there was no efficient route for using it properly. Visibility across the supply chain often became limited.
SDL wanted to build something more connected.
That is why the wider SDL Group invested across multiple stages of the timber process, including:
Forestry and harvesting operations
In-house haulage
Sawmilling and timber processing
Biomass production
Renewable fuel supply
CHP and energy systems
Material recovery and by-product utilisation
Wood Pellet Manufacturing
That vertical integration allows timber to move through far more defined and efficient routes across the wider SDL operation.
Higher-grade sawlog can move directly into processing, while lower-grade material and by-products continue through biomass, renewable fuel, woodchip and CHP systems, rather than being unnecessarily wasted further down the chain.
Because haulage, processing, biomass, and recovery operations sit within the same wider group structure, SDL is able to maintain far greater visibility over how timber moves from woodland through to end use. It reduces delays, improves utilisation of harvested material, and helps ensure more of the crop is used productively rather than lost through fragmented supply chains or limited processing routes.
More importantly, it helps keep more of the value, infrastructure, and processing capability within the UK timber industry itself.
British sawmilling still has a role to play
Sawmilling is sometimes viewed as an old industry. But in reality, it remains deeply connected to modern demand.
Construction still needs timber.
Infrastructure still needs timber.
Landscaping, fencing, packaging, manufacturing, biomass, and renewable energy all rely on timber in different ways.
The difference today is that markets expect consistency, efficiency, and scale alongside sustainability and traceability.
That is where domestic processing becomes important. Without British sawmills, more raw material leaves the country unprocessed while finished timber products return through longer global supply chains. That weakens domestic capability over time and reduces visibility over how timber is handled from woodland to end use.
Strong domestic processing supports the wider forestry ecosystem around it.
It supports harvesting contractors.
It supports haulage networks.
It supports machinery investment.
It supports rural employment.
It supports active woodland management.
And increasingly, it supports businesses looking for greater transparency around where their materials come from.

Competing in a modern market
British sawmilling now operates in an intensely competitive global market, which means the industry cannot rely on tradition alone to remain viable long term.
Modern timber markets demand consistent supply, efficient processing, reliable logistics, renewable energy integration, and far better utilisation of harvested material than was expected even a generation ago.
For SDL, sawmilling forms part of a much wider long-term investment strategy designed around keeping British timber commercially viable within those modern conditions.
That includes continued investment into:
Modern sawmilling infrastructure
Forestry machinery and harvesting capability
Integrated haulage operations
Biomass infrastructure
Material recovery and by-product utilisation
The wider aim is to make better use of the full harvested crop wherever possible.
Higher-grade material can move into sawn timber products, while lower-grade timber and by-products continue through biomass, woodchip, CHP fuel, and pellet production across the wider SDL Group rather than being unnecessarily wasted.
That circular approach not only improves material utilisation, but also helps strengthen the long-term economic resilience of British forestry itself.

This is bigger than one business
Forestry does not survive on tree planting alone.
It relies on the industries around it staying viable too. Harvesting teams, haulage operators, sawmills, machinery, processing infrastructure, and businesses willing to invest in British timber all play a part in keeping UK forestry commercially sustainable long-term.
Once domestic processing capability disappears, it is extremely difficult to bring back.
That is one of the reasons SDL continues investing across the wider timber operation rather than treating sawmilling as a standalone business.
By controlling more of the process internally, from harvesting and haulage through to sawmilling, biomass, and renewable energy production, SDL can keep more British-grown material moving through defined UK supply chains while making better use of the full harvested crop.
The aim is simple.
Keep British timber working within British industry, support active long-term woodland management, and help protect the infrastructure that allows the sector to remain viable for future generations.
