What are the cost implications of timber waste on construction projects?

Timber waste costs include: material cost of wasted timber (at current prices, 15% waste on a £50,000 timber package = £7,500 lost material), skip hire and disposal fees (£200–400 per skip, multiple skips per project), landfill tax (£103.70/tonne in UK 2026 for non-inert waste), labour time handling waste (estimated 2–5% of carpenter time), and environmental compliance costs (Site Waste Management Plan preparation and monitoring). Total waste-related costs typically represent 3–8% of the timber package value.

Total waste-related costs typically represent 3–8% of the timber package value. Investing 0.5–1% of package value in waste reduction measures (software, storage, training) typically delivers 3–5× return through reduced material purchasing and disposal costs.
