A commercial stump grinding quote depends on the stumps and the site: their number and diameter, access for the machine, what happens to the grindings, and how you will use the ground afterwards.
Two sites with the same stump count can produce very different prices. One has level tarmac and a straight run in. The other has a soft verge, a retaining wall, and a service duct running under the root zone.
This guide explains what affects the cost of commercial stump grinding, what should be included in a quote, and what information to send so the price you get back is one you can compare.
What affects the price?
Domestic grinding is often priced per stump. That works in a garden where the machine goes through a gate and the chips get raked into a border. A commercial site may also need: a permit to work, protection for surfaces and services, coordination around tenants and deliveries, and material that leaves site under waste rules.
A per-stump figure is only part of the picture. Check whether the quote covers the whole job or leaves arisings removal, reinstatement, or service location for you to arrange separately. Allow for those costs before comparing totals.
What to measure and check
Give the contractor measurements and site details before asking for a price. Use a numbered plan with photographs to show:
- Number of stumps and the diameter of each one at ground level.
- Multi-stem stumps and buttresses, which behave like more than one stump.
- Species and condition. Soft, rotten wood grinds quickly; dense dry timber and embedded grit slow the machine and wear the cutting teeth.
- Ground conditions and slope, including soft ground that won't carry a machine.
- The surface around each stump: grass, tarmac, block paving or concrete.
- Where the grinder can stand, and the route from the site entrance to that position.
- Anything overhead, and anything below: drains, ducts, cables, water and gas.
Check the access route
Grinders come in different sizes for a reason. A compact machine passes through a standard gateway and works in a tight space. A larger machine clears a big stump faster but needs a wider route, firmer ground and more clearance to work safely.
Access is more than gate width. It includes the load a surface can take, whether a car park deck or basement slab sits underneath, whether the route has to stay open for fire access and deliveries, and what time of day the work can happen. A quote that assumes round-the-clock access to a shared yard is not the same quote as one that prices two night shifts in a closed car park.
If the route can't take the machine, the options change the price quickly: a smaller grinder, more handling or barrowing of arisings, or a different method for the stump. Each should appear on the quote as an assumption, so you can see what happens if it is wrong.
How deep does the stump need grinding?
Agree the grinding depth for the intended use of the ground. It is measured down from ground level and determines how much of the stump and surface roots are removed.
| What the ground will be used for | What the specification needs to say |
|---|---|
| Grass or soft landscaping | Grind below the level that will be cultivated allowing for remaining timber, future decay and settlement, then fill with a suitable growing medium. |
| Hardstanding, paving or a vehicle route | A deeper grind and a backfill that will not settle under load. An engineer should confirm what the sub-base needs. |
| Planting in the same spot | Depth set by the replacement planting, with the roots left below the grind considered. |
| No planned use, the stump is a trip hazard or an eyesore | The shallowest sensible depth, with the level restored and the chips dealt with. |
Whatever depth is agreed, timber and roots below it stay in the ground and decay over time. If the site needs the whole root system out for foundations or services, that's a different operation with its own price and reinstatement.
Services and hidden obstructions
Grinding is a high-speed cutting operation at ground level, which is exactly where services, footings, kerbs, old fence posts and buried rubble sit. HSE guidance on work near underground services sets out three elements of a safe system of work: planning the work, locating and identifying the buried services, and safe excavation where digging is needed. The same discipline applies before a grinder goes in.
Before the work, agree who provides utility plans and whether a cable avoidance scan is part of the job.
A cable avoidance tool can help locate some buried services, but cannot detect every service or prove an area is clear. Competent planning must combine records, suitable locating methods and any further investigation needed. Meter boxes, valve covers, manhole covers and the line a supply takes from the boundary are all clues to where those services run.
If plans or a scan show a service under or beside a stump, the quote should say how it will be dealt with: a change of approach, a shallower grind, or hand work around the service. Hidden concrete and metal are the other cost. Cutting teeth are consumables, and a stump with a concrete collar or an old post through it takes more machine time than a clean cut.
What plans don't always show is what was buried after they were drawn. Use records and suitable site investigation together; neither drawings nor a scan alone establish safe clearance.
Grindings, waste and making good
Grinding turns a stump into a mixture of chips, soil and stones, and the volume usually surprises people.
Where arisings stay on site, agree where they go and whether that's acceptable to whoever manages the land. Where the material is waste, the waste duty of care applies to everyone who produces, keeps, carries or disposes of it: keep it safe, transfer it only to a business authorised to take it, and keep the paperwork.
Check that the contractor's registration covers the load, and ask for the waste transfer note afterwards. Document non-hazardous waste transfers with the required information and retain the records for two years. A season ticket may cover qualifying repeated transfers; confirm the arrangement rather than assuming each load always requires a new note.
Registration is tiered and the upper tier is renewed every three years, so check the register entry is current.
Check whether the quote includes reinstatement: making good the ground after grinding. Agree the material used to fill the void, how it's compacted, the final level, the surface finish and who signs it off. On a site that will be handed over or reopened to the public, that sign-off matters as much as the grinding.
Comparing two quotes for the same stumps
Compare what each quote includes, line by line, before comparing the totals.
| Detail | What to ask for |
|---|---|
| Scope | Every stump listed with its diameter, and the agreed depth for each area. |
| Access | The machine type stated, with the access route it assumes. |
| Services | Who provides plans, who scans, and what happens if a service is found. |
| Arisings | Left on site or removed, where they go, and the documentation provided. |
| Reinstatement | Backfill material, level tolerance, surface finish and who signs it off. |
| Exclusions | Stated plainly, including any assumption about hidden concrete or ground conditions. |
| Programme | Working hours, access windows and any phasing around operations. |
A quote that excludes removal of grindings, reinstatement and service location covers less work. Add the missing lines before you compare.
As a hypothetical example, twelve stumps along a boundary would usually be quoted differently from twelve stumps scattered across a live car park, even though the count is identical, because access, working hours and surface protection all change.
The brief to send with your enquiry
These details will help the contractor give you a more accurate quote:
- A plan or sketch showing each stump, numbered, with the diameter at ground level.
- What the ground will be used for after grinding, including any construction or planting planned.
- The access route, gate widths and surface types, with photographs.
- Any known services, drains or structures near the stumps.
- Working hours, site rules, permits and any time the area must stay open.
- Who will check and sign off the finished level.
One more check before work starts: where the tree was protected by a Tree Preservation Order or stood in a conservation area, check that the felling followed the applicable consent, notice or exemption route. Agree the position on the stump with the appointed arboriculturist or local planning authority before grinding.
If you're preparing a site for development, reopening a car park or clearing stumps after felling, we'll inspect the stumps for the quotation, agree depths and reinstatement, and set out what the price includes and excludes.
A free quotation visit covers tree works only. A formal survey or report is commissioned separately, with an agreed scope, named author and fee.
