What a survey establishes
- ✓The species, and whether it runs. Everything else follows from this, and it is routinely got wrong in both directions.
- ✓How far it has actually gone. The canes are not the extent of it. This is the fact that decides both how serious the situation is and what it costs to fix.
- ✓What it has reached. Paving, a drive, drains, a wall footing, a boundary — each changes the job and the price.
- ✓Whether containment is still realistic, or whether it has spread far enough that removal is the only honest answer.
- ✓What the work would involve, to what depth, and where the excavation boundary would sensibly be drawn.
What happens during the visit
- Identifying the plant
Canes, joints, branching pattern, leaves and the base. Usually quick for an experienced eye, and enough to establish the genus and whether it is a runner.
- Reading the pattern above ground
Where canes and new shoots are, and how they are distributed. This is the map of the rhizome network, which is why cutting everything down beforehand is unhelpful.
- Exploratory digging
Small holes at the edges of the stand and around anything the rhizomes may have reached. This is the part that cannot be skipped, and the part a photograph cannot replace.
- Checking what's at risk
Paving joints, drive edges, drain chambers, wall footings, fence lines, and any airbricks or cavity where bamboo sits against the house.
- The recommendation
Contain or remove, to what depth and along what line, with the reasoning. If you have asked for a written report, this is what it says.
When it's worth paying for a written report
Most people do not need a standalone survey. If you simply want the bamboo dealt with, the assessment happens as part of quoting — nobody can price a rhizome network without first working out how big it is — and you get the substance without paying separately for the document.
A written report earns its cost in three situations:
A neighbour dispute. An independent written account of the species, the extent and the direction of spread is what turns an argument into a fact, and it is what a solicitor will want if it goes further.
A sale or a purchase. Something to hand a buyer, a seller or a conveyancer, so the discussion is about a known quantity rather than a worry.
Damage that may become a claim. Evidence gathered while the rhizomes are still in the ground and traceable is worth considerably more than evidence gathered after they have been dug out.
Using our comparison service is free and you never pay us anything. What each firm charges for a visit is their own commercial decision and it varies — some treat it as the cost of winning the work, others charge for a detailed survey.
A survey carried out purely to produce a written report, with no work attached, is a separate professional service and is normally chargeable. Ask on the first call and get any fee confirmed in writing before anyone attends.
Frequently asked questions
How much does a bamboo survey cost?
A standalone written report typically runs £150–£500 depending on the size of the garden, how much exploratory digging is needed and how formal a document you want.
Where you are getting quotes for work, many firms carry out the assessment as part of quoting rather than charging separately — but that varies by firm, so ask before they attend rather than after.
Do I need to be there for the survey?
It helps a great deal. You know when the bamboo was planted, where you have seen shoots appear, and what has changed — all of which is genuinely useful and none of which is visible on the day.
You will also get far more out of the visit by asking questions while someone is standing in front of the plant than by reading a report a week later.
Will they dig up my garden to survey it?
Some digging, yes, and it is unavoidable — the extent of a rhizome network cannot be established from the surface. But it is exploratory rather than excavation: small holes at the edges of the stand and around anything at risk, backfilled afterwards.
If a firm proposes to establish the extent without putting a spade in anywhere, ask how. There is not a good answer.
Can I just send photos instead?
For identifying the species, often yes, and many firms will give you an initial view from a clear photograph of the canes, leaves and base. That is genuinely useful and it settles a lot of enquiries either way.
For extent, no. Photographs show you the canes, and the canes are not the problem — the network under the lawn is. If the answer you need is “how far has it gone”, someone has to come and look.
