What does a knotweed survey cost?
Ask for a written scope before comparing amounts. Clarify the areas inspected, site access, report format, intended purpose, travel, follow-up, VAT and exclusions. A treatment quotation and a survey quotation cover different work.
What should a written survey quotation let you compare?
| Compare | Ask for this in writing | Why it matters |
|---|---|---|
| Report purpose | Inspection scope and intended use, including any written lender request. | A different instruction can require a different report. |
| Access and exclusions | Areas to inspect, inaccessible areas and resulting limitations. | A low advertised amount may exclude work needed for your question. |
| Named professional | Who will inspect and what relevant competence evidence is available? | A brand name or badge does not identify the person doing the work. |
| Fee conditions | VAT, travel, follow-up, variations and quote expiry. | The final payable amount needs the actual property and scope. |
| Separate work | Any proposed treatment, monitoring or guarantee quoted separately. | Inspection and management work cover different instructions. |
PCA guidance says the instructions, scope and limitations of a survey should be clear. No price or guarantee is verified merely because a provider advertises it.

Why does the site show “Quote Required”?
Knotweed Clarity has no current, independently verified survey tariff. This comparison checklist describes questions to ask, not an offer from a provider. Ask an appointed professional to price the agreed inspection and reporting scope for the actual property.

What is the price of a Japanese knotweed survey?
Quote Required. Knotweed Clarity has no verified current survey price schedule. Request a written quotation for the actual property and intended report purpose rather than treating an advertised starting price as a complete offer.
Site scope or questions to discuss with your adviser; not a professional finding.
What should I compare in survey quotations?
Compare the inspected areas, access restrictions, report purpose, named professional, exclusions, travel charges, follow-up, VAT and quotation expiry. Ask for unclear terms in writing. PCA guidance supports clear survey instructions, scope and limitations; it does not establish a price for your property.

Is a treatment quotation the same as a survey quotation?
No. A survey quotation describes inspection and reporting work. A treatment quotation describes proposed management work and any monitoring. Ask the provider to price each scope and explain any separate guarantee or follow-up terms.
