Contract Chipping

Professional Contract Wood Chipping Services

Simpson Arboriculture provides specialist contract chipping services for forestry contractors, estates, landowners, tree surgery companies, site clearance projects and other commercial customers.
Using our Valtra S416 tractor and Jenz HEM 593Z biomass chipper, we can process large quantities of timber efficiently on site, turning whole trees, roundwood, brash and other suitable woody material into consistent woodchip.
Based near Grantham, Lincolnshire, we provide contract chipping throughout Lincolnshire, the East Midlands, East Anglia and further across the UK for larger projects.

High-Capacity Biomass Chipping
Our tractor-powered Jenz HEM 593Z gives us the capacity to process substantial volumes of timber efficiently.
The machine can process a variety of woody material, making our contract chipping service suitable for:
  • Whole trees and roundwood
  • Forestry timber
  • Brash and branchwood
  • Arb arisings
  • Site clearance timber
  • Woodland management operations
  • Biomass production
Material can be chipped directly into walking-floor trailers, agricultural trailers or other suitable vehicles, allowing processed material to be efficiently moved from site.

    Woodchip specifications


    G30, G50 & Biomass Woodchip Production
    Where the end use requires it, timber can be processed into different chip specifications suitable for biomass woodchip applications.
    This makes our contract chipping service particularly useful for forestry and commercial projects where timber needs to be processed efficiently into a usable biomass product rather than treated simply as waste.
    If you have a particular chip specification or end use in mind, speak to us before the job so that we can discuss the material, required chip size and intended application.
    Complete Chipping & Haulage Service
    One of the advantages of using Simpson Arboriculture is that chipping and haulage can be coordinated through the same company.
    Alongside our contract chipping equipment, we operate our own walking-floor haulage, allowing us to arrange collection and movement of large volumes of woodchip where required.
    This can provide a straightforward solution for projects where timber needs to be processed on site and the resulting chip transported elsewhere.
    Who Uses Our Contract Chipping Service?
    Our contract chipping service is suitable for organisations producing significant volumes of timber or woody material, including forestry contractors, tree surgery businesses, estates, landowners, local authorities, construction and site clearance contractors, woodland managers and biomass operators.
    We can undertake both one-off contract chipping projects and ongoing work.
    Why Simpson Arboriculture?
    We have been working within arboriculture and forestry since 2006 and have developed our machinery fleet around efficiently managing timber from tree to end use.
    Our combination of forestry equipment, biomass chipping and in-house haulage means we can provide more than simply a chipper and operator.
    For larger projects, we can help plan how material is stacked, processed, loaded and transported to keep the operation moving efficiently.
    Looking to Buy Biomass Woodchip?
    If you don’t have timber to process and instead need a reliable supply of ready-produced woodchip, we also supply G30 and G50 biomass grade virgin woodchip.
    Our biomass woodchip is produced from UK timber sourced through our own forestry operations and is available for commercial biomass boilers, pellet production and power generation.

    • Sustainable source of energy

      Woodchip biomass can be a valuable renewable alternative to finite fossil fuels. The focus of bioenergy initiatives is to ensure the use of land for bioenergy is economically, environmentally and socially sustainable.

    Contract chipping is where we bring our specialist biomass chipping machinery to your site to process your timber or woody material into woodchip. It is particularly suitable for forestry, woodland management, site clearance and other projects generating large volumes of timber.

    Our contract chipping setup includes a Valtra S416 tractor and Jenz HEM 593Z chipper, providing a high-capacity solution for commercial and forestry chipping operations.

    We can process a range of suitable woody material including whole trees, roundwood, forestry timber, branches, brash and timber generated from site clearance and arboricultural operations.
    We would assess the material and site requirements before undertaking the work.

    Yes. Our contract chipping operation can be used to process suitable timber for biomass woodchip production. If you require a particular specification, please tell us the intended use when enquiring.

    We can produce different chip sizes for biomass applications, including G30 and G50, subject to the material and project requirements.

    Yes. We operate our own haulage equipment, including walking-floor trailers, so we can discuss transporting the resulting woodchip as part of the project.

    Alternatively, we can chip directly into your own suitable trailers or vehicles.

    For our contract chipping service, we process timber belonging to or managed by the customer.
    If you want to purchase woodchip from us instead, please visit our Biomass Woodchip Supply page for information about G30 and G50 virgin biomass woodchip.

    Yes. We can undertake one-off projects as well as regular or ongoing contract chipping work.

    We are based near Grantham in Lincolnshire and regularly work throughout Lincolnshire and the surrounding regions. We can travel further across the UK where the scale of the project makes this practical.

    It helps if you can provide the site location, approximate quantity of timber, type and size of material, how it is stacked, site access, intended use of the woodchip and whether haulage is required.
    Photographs of the timber and working area are also useful when initially assessing a project.
