The short answer
Removing a tree stump in the UK typically costs around £100–£400 per stump by grinding, and more — often £250–£800+ — where the whole root system has to be excavated for groundworks. The difference matters for building: stump grinding chips the stump to below ground level but leaves the roots behind, which is fine for landscaping but not always acceptable under foundations; full excavation digs out the stump and main roots so the ground can be built on. Price depends on the stump diameter, the species and root spread, access for machinery, and what happens to the arisings and any soil. Large, mature stumps, awkward access, or a stump protected by a Tree Preservation Order all push the cost and the paperwork up.
For groundworks, removing a stump is not just tidying up — the roots can sit where foundations need to go, and decaying roots leave voids. The figures below are typical UK ranges, with what changes them.

Grinding versus full removal
There are two distinct jobs, and groundworks usually needs the more thorough one:
- Stump grinding: a machine grinds the stump into chippings to around 150–300 mm below ground, fast and relatively cheap at roughly £100–£400 per stump. The main roots stay in the ground, so this suits gardens and landscaping but may not be enough where you intend to build.
- Full excavation: a digger removes the stump and the main root ball, leaving ground that can be reinstated and built on. This is dearer — commonly £250–£800+ — because of the machine time, the larger hole and the spoil and arisings to remove.
For foundations, the concern is that buried roots occupy the foundation zone, and as they decay they leave voids that can cause settlement. Your engineer or Building Control may therefore require roots removed rather than just ground.
| Method | Typical figure | Suits |
|---|---|---|
| Stump grinding | £100–£400 | gardens, landscaping |
| Full excavation | £250–£800+ | ground to be built on |
| Large / mature stump | higher end+ | wide root spread |
| Multiple stumps | rate per stump falls | whole-plot clearance |

What changes the price
Within those ranges, the main variables are straightforward. Size is the biggest — a small ornamental stump is quick, while a mature oak, beech or conifer with a wide, deep root plate takes far longer and a bigger machine. Species matters because some trees spread shallow, wide roots and others send down deep tap roots, changing how much has to be dug. Access decides what plant can reach the stump: a grinder or digger needs room, and a back-garden stump reached only on foot is slower and dearer.
Then there is disposal. Grinding produces a heap of chippings that can often be reused as mulch on site; full excavation produces a stump, roots and excavated soil that may need carting away, adding muck-away cost. Where several stumps are cleared in one visit, the per-stump rate usually falls because the team and machine are already on site.
Roots, foundations and approvals
For groundworks the real issue is what the tree leaves behind. Live roots in the foundation line have to be cleared so footings can be formed correctly, and on shrinkable clay the previous presence of a large tree affects foundation design — removing a thirsty tree can cause clay to swell (heave), which an engineer must allow for, just as a nearby live tree can cause shrinkage. This is why foundation depth near current or former trees is set by the engineer and Building Control, not chosen on site.
Decaying roots left in place create voids as they rot, which can lead to settlement under slabs or foundations, so full removal is often specified for the build footprint even if grinding would do elsewhere. On the legal side, beyond TPOs and conservation areas, large-scale clearance and any felling should respect nesting-bird season and wildlife protections. A groundworker or arborist who sees the site can advise whether grinding suffices or full excavation is needed, and price accordingly; the figures here are for budgeting.
Practical steps before the machine arrives
A little preparation makes stump removal cheaper and avoids legal trouble. Sensible steps for a UK plot are:
- Check protection status: confirm with the council whether the tree has a TPO or sits in a conservation area before any work; consent can take weeks, so allow time.
- Locate services: roots often grow alongside drains and cables, so have underground services traced before excavating around a stump.
- Decide the method early: agree with your engineer or Building Control whether grinding suffices or full root removal is required for the build footprint, so it is priced once, not twice.
- Plan the arisings: decide whether chippings stay on site as mulch or the stump and roots are carted away, and price disposal accordingly.
- Mind the season: clearance of trees and large shrubs should respect nesting-bird protections, typically most relevant in spring and early summer.
Getting these sorted before the grinder or digger turns up means the job runs in a single, efficient visit rather than stopping for consents or service checks. On a plot with several stumps, clearing them together in one mobilisation is markedly cheaper per stump than calling the team back repeatedly.
Frequently asked questions
Is stump grinding enough before building, or do I need full removal?
It depends on where the stump sits. For landscaping, grinding is usually fine. Under foundations or a slab, the roots often have to be fully excavated, because buried roots occupy the foundation zone and leave voids as they decay, risking settlement. Your engineer or Building Control will advise what is required for the build footprint.
Do I need permission to remove a tree stump?
If the tree or stump is protected by a Tree Preservation Order or is in a conservation area, you need written consent from the council before carrying out works, and removing it without consent is an offence. An ordinary, unprotected garden stump on your own land generally does not need permission to remove.
Why do tree roots matter for foundations on clay soil?
On shrinkable clay, trees draw moisture and cause the ground to shrink, while removing a large tree can let the clay swell, or 'heave', as moisture returns. Both movements affect foundations, so the engineer designs the depth to suit, and the presence or removal of trees near the footprint must be considered before building.
