Contract Biomass Chipping in Glasgow

  • Fully insured tree surgeons working to British Standard BS3998
  • NPTC/Lantra certified on wood chipper, timber crane, tractor and forwarder trailer operation
  • Free, no-obligation site visit before any chipping is booked

If you're clearing woodland, managing hedgerows across an estate, or keeping a biomass boiler fed through the winter, contract biomass chipping in Glasgow usually works out cheaper and less hassle than buying a chipper outright or paying to have green waste hauled off site. Glasgow Trees brings a tractor-mounted or towable wood chipper to you, works through your own timber, brash and hedge cuttings on site, and either heaps the chip up for your own use or loads it out, depending on what's agreed at the quote stage.

This isn't a one-visit garden clean-up service - it's set up for the volumes that estates, farms, other contractors and land managers actually generate: a felling season's worth of conifer thinnings, a hedge-cutting round's worth of cuttings, or a storm's worth of windblown timber. We've traded as Glasgow Trees since 2005, and on a chipping job that history mostly comes down to practical judgement calls: what a morning's conifer brash actually weighs, how fast a given machine chews through mixed hardwood versus softwood, and when a pile's worth waiting on a second pass rather than trying to clear it in one go.

What Goes Into the Chipper, and What Doesn't

  • On-site chipping of tree surgery arisings - branches, brash and small-diameter stems left after felling, pruning or crown reduction
  • Processing storm-damage and windblown timber that's already been dropped and sectioned
  • Chipping hedge cuttings and scrub cleared during woodland thinning or estate boundary work
  • Scheduled, repeat visits set up around your felling or hedge-cutting programme rather than a single callout
  • Heaping chipped material at an agreed point on site for your own use, or loading it out if you need it removed
  • A tractor-mounted or towable diesel chipper sized to the site's volume and access, run by NPTC/Lantra qualified operators
  • Use of a timber crane or forwarder trailer to bring material to the machine on larger or awkward sites

Not Included / Costed Separately

  • Haulage of chip beyond the agreed drop point - moving it further afield is quoted and arranged separately
  • Stump removal - chipping only deals with above-ground material; stump grinding is a different job
  • Certifying the resulting chip under the Biomass Suppliers List for RHI purposes - that sits with your fuel supply chain, not with the chipping contractor
  • Long-term drying or storage of chip - freshly produced chip comes off site green and needs stacking under cover before it's boiler-ready
  • Sourcing timber from elsewhere - this service processes material already on your own site, it doesn't supply separate biomass feedstock

One Visit or a Running Contract: How the Job Gets Set Up

  1. Call and volume check -- Tell us roughly how much material is involved, what it actually is - conifer brash, hardwood hedge cuttings, storm timber, a felling block's worth of stems - what access a tractor or towable machine has on site, and whether this is a single clearance or something that'll need coming back for.
  2. Free site visit -- We walk the ground itself rather than pricing off a phone description - checking gateway and track widths, how wet or firm the site is underfoot, overhead lines, and where chip can be heaped or loaded out - then confirm machine size and a per-tonne or day rate before anything's booked.
  3. Chipping day, gate to stockpile -- The crew brings the chipper and, where stems are lying away from where it can park, a timber crane or forwarder trailer to bring material in. Chip is heaped at the agreed point or loaded straight into a trailer or bunker as the work goes, so a stockpile doesn't build up and block your own access on longer jobs.
  4. One-off close-out, or a date set for next time -- A single clearance gets signed off there and then. For a running arrangement, the next visit is timed around how fast your site actually generates material - after the next felling block, hedge round or storm clear-up - rather than against a fixed calendar date that might not match the work.

What a Tonne of Chip Actually Costs to Make

A felling block that yields around forty tonnes of stacked softwood is a useful way into how the maths actually works on this job. Processed through a machine capable of 15-20 tonnes an hour, that block clears in a few hours once material is fed steadily, and a rate around £20 a tonne is realistic once there's enough volume to keep the machine running without gaps. Feed the same machine an inconsistent trickle instead - a pile here, a pile there, gaps while someone tracks down the next stack - and the day rate doesn't change but the tonnage got through in it does, which is a large part of why smaller-scale contract jobs chipping a farm or estate's own wood supply often land at £40-50 a tonne rather than £20: the machine's capable of more, the site just isn't generating enough on a given day to keep it fed continuously. Straightforward contract quotes on steadier volume commonly come in around £11-£15 a tonne, and the very large industrial chippers capable of 60 tonnes an hour - well beyond the scale of most estate or farm jobs in this area - can push costs as low as £5 a tonne where the throughput justifies that kind of kit. Set any of those figures against buying in ready-made biomass wood chip fuel instead - typically £50-90 a tonne, and up to £120 a tonne for smaller bought-in orders - and processing timber that's already sitting on your own ground comes out cheaper in almost every case where there's enough of it to make a visit worthwhile. None of these numbers replace an actual quote: the softwood-to-hardwood mix, how spread out the material is across the site, and ground access all move the final rate, which is why pricing gets confirmed at the visit rather than over the phone.

Contract Chipping Against the Alternatives

Option Typical volume How it's costed Best suited to
One-off tidy-up chipping Under a tonne, single visit Usually included in the job price or a small callout fee Domestic gardens after a pruning or felling job
Contract biomass chipping Several tonnes upward, ongoing Per-tonne rate (roughly £11-£50/tonne depending on machine size and mix) Estates, farms and sites feeding a boiler or generating regular clearance material
Buying your own chipper Any volume, whenever needed Machine purchase plus fuel, servicing, storage and an operator's time Only sites with year-round volume high enough to justify ownership

One Crew, Six Certificates, No Second Contractor Booked

Take a felling block on an estate with a couple of hundred stacked softwood stems, half of them lying fifty or sixty yards from the only spot a chipper can actually get parked. The wood chipper ticket in the team's NPTC/Lantra record covers turning that material into chip once it reaches the machine, but getting it there in the first place is a different job entirely: the FMO forwarder trailer and timber crane certificates cover dragging or lifting stems out of the plantation and onto a trailer, the 360 excavator ticket covers shifting anything too heavy or awkward to move by hand, and the FMO tractor and FMO line skidder certificates cover hauling a loaded trailer over ground that would bog an ordinary vehicle down to the axles. A flail ticket handles boundary hedge material that's grown too thick and woody to feed straight into a chipper, and a telehandler certificate covers loading the finished chip once it's made, into a trailer, a bunker or wherever it's heading next. Split any one of those jobs off to a different contractor and a chipping visit stalls waiting on someone else's machine and someone else's diary; keep it under one set of certificates and the stems come out of the plantation, through the chipper and off site inside a single booked visit. Every stage of it is carried out to British Standard BS3998 by a fully insured crew that's held these tickets well before this particular contract was ever booked, and working out which of them a given site actually needs costs nothing - the site visit and the quote that follows it are both free.

Same Machine, Different Ground: What Changes From Site to Site

The chipper itself barely changes between one job and the next - what changes is the ground underneath it, and that decides more about how a visit runs than the species of tree ever does. Flat, open farmland is the easiest ground going: South Lanarkshire's arable and mixed livestock land around Hamilton, East Kilbride and the Avon valley lets a larger towable machine move between field gateways without needing to be lifted over a ditch or a dyke, which is exactly the ground that suits the higher end of the tonnage-per-hour range. Heavier clay ground behaves differently - country estates and smaller farms in Renfrewshire and East Renfrewshire around Lochwinnoch and Eaglesham rut fast once the weather turns, so timing a visit for a dry spell, or bringing a lighter machine that won't cut ruts into the field, matters more there than the site's actual timber volume does. Woodland blocks are a third category again: out towards Old Kilpatrick and the Kilpatrick Hills, and up towards Loch Lomond's southern shore, conifer thinnings sit in stands too far from any road for a chipper to reach directly, which is where a forwarder trailer earns its keep bringing felled timber down to wherever the machine can actually be parked. Estate policies and parkland north of the city, around Milngavie, Strathblane and the foot of the Campsie Fells, tend to generate steadier, smaller volumes spread across the year rather than one seasonal clearance, which fits a running contract better than a single large visit ever would. Within Glasgow itself, most of the work is park and estate ground under council or private management - felling and hedge-cutting arisings chipped and heaped where they lie rather than skipped away, ground that behaves more like the estate category above than like open farmland. Stirling and Falkirk (Bo'ness) sit at the edge of where this service reaches, and get booked in where the tonnage on a particular estate contract makes the extra travel worth it, rather than as routine ground.

Contract Chipping Questions We Get Asked

What is contract chipping and how does it differ from a normal chipping job?

A normal chipping job is us chipping the arisings from our own tree surgery work as part of a felling or pruning job. Contract chipping is a standalone service where we bring a chipper to process material you already have on site - your own felling, hedge cuttings, storm timber or woodland thinnings - either as a one-off for a large pile or as a running arrangement timed around your ongoing work.

How much does contract wood chipping cost per tonne in Glasgow?

Rates commonly sit around £11-£15 a tonne for straightforward jobs, though smaller-scale contract work using your own wood supply can run £40-50 a tonne, coming down towards £20 a tonne once volume is high enough to keep a larger machine fed continuously. The exact figure depends on machine size, access and the mix of material, so a firm price needs a site visit.

Can you chip my own tree surgery arisings on-site rather than me hauling them away?

Yes - that's the core of the service. Rather than skip-loading brash and branches to be taken elsewhere, we bring the chipper to the pile, process it where it lies, and either heap the chip for you or load it out, whichever suits your site.

What size of chipper do you bring for a large clearance or estate job?

It depends on volume and access. Smaller towable machines suit sites with tighter gateways or where material is spread across several areas; on larger estate or farm jobs with good tractor access, a higher-capacity machine gets through more tonnes per hour and brings the per-tonne cost down. We confirm this at the site visit rather than guessing over the phone.

Is biomass wood chip a cost-effective fuel compared to oil or LPG heating?

Wood chip is generally cheaper per unit of heat than oil or LPG, which is why estates and farms with their own timber supply often find it worth chipping material on site rather than paying to have it removed and then buying in a different fuel. Bought-in delivered chip runs £50-90 a tonne and can reach £120 a tonne, so processing timber you already have is usually the more economical route where volume supports it - but the actual saving depends on your boiler's efficiency and how much material your land produces.

What happens to the chip once it's made - do you take it away or leave it?

Whichever you need. Many estate and farm clients want the chip left on site, heaped near the boiler store or a covered area. If you'd rather it was removed, we can load it out and arrange haulage, though that's costed separately from the chipping itself.

What moisture content does wood chip need before it's usable in a biomass boiler, and does chipping timing affect that?

Most biomass boilers want chip at roughly 20-30% moisture content or below; freshly chipped green timber typically comes in well above that and needs weeks to months stacked under cover before it's dry enough to burn efficiently. Chipping material too far in advance of when it's needed, or chipping it and leaving it uncovered, works against you - timing the chipping visit around your drying and storage capacity matters as much as the chipping itself.

Can chipping be scheduled alongside routine hedge and woodland management to keep a boiler supplied through winter?

Yes, and it's one of the more sensible ways to run a contract - timing chipping visits to follow your hedge-cutting rounds or woodland thinning means the chip is generated in stages through the year rather than all at once, which suits both storage space and a boiler's ongoing demand better than one large annual pile.

Does the mix of softwood and hardwood on a site affect the per-tonne rate?

It can. Softwood conifer material, common across Glasgow's parks and estate plantings, tends to chip faster and more consistently than mixed hardwood hedge cuttings and branch wood, which can include thicker, knottier sections that slow the machine down. A site with a heavier hardwood mix may take longer per tonne, which is factored into the quote once we've seen what's actually there.

Book a Site Visit Before Your Next Clearance or Boiler Season

If you've got a felling block, a hedge-cutting round or a storm clear-up generating more timber than you want sitting around, or a biomass boiler that needs a steady chip supply through the colder months, it's worth getting a site visit booked in before the pile grows any bigger. Get in touch to talk through your volume and access, and we'll confirm machine size and pricing on the visit itself - no obligation either way.
