The problem knotweed creates for professionals
Knotweed rarely turns up at a convenient moment. It appears in a viewing photo, a valuation inspection or a site walk-round, and suddenly a decision is on hold. Guess wrong in either direction and it costs: call knotweed on a harmless look-alike and you've spooked a buyer for nothing; miss the real thing and you're exposed to a delayed completion, a down-valuation, or a disclosure dispute later. What professionals need is a quick, credible answer - not a two-week wait for a site visit just to find out whether it's worth a site visit.
How iD Pro helps
iD Pro turns a photo into an accredited opinion. You (or your client) photograph the plant in the app; a PCA CSJK accredited surveyor reviews it in the iD Pro Portal and confirms whether it's Japanese knotweed, usually within 24 hours. You get a clear, documented result and a dated report you can keep on file or pass on. It's the fast first line that tells you what you're dealing with - and whether a formal survey is the next step.
Who it's for
Estate agents
Screen a property before it goes live, answer a nervous buyer on the spot, and document that you flagged and checked a suspect plant. A quick accredited confirmation keeps a sale on track instead of stalling it for weeks.
Surveyors & valuers
Use it as a rapid second opinion on borderline plants spotted during an inspection, and give clients an early, documented answer while a full assessment is arranged.
Property investors & developers
Triage sites and auction lots before you commit. Knowing whether a stand is knotweed - and roughly how significant - helps you price the risk, budget for treatment and avoid nasty surprises after exchange.
Letting & managing agents
Deal with tenant and leaseholder reports quickly, keep a dated record for the managing file, and decide whether a specialist needs to be instructed.
Conveyancers & auctioneers
Support TA6 disclosure conversations with a documented check, and give bidders or buyers a clear, early picture rather than an unanswered question.
Why the accreditation matters
Anyone can offer an opinion on a plant; the value is in who gives it. iD Pro confirmations come from surveyors holding the PCA's CSJK qualification - the recognised UK standard for Japanese knotweed competence. For a professional audience, that's the difference between a hunch and a credible, defensible check.
What it costs
iD Pro is £12.99 a month, with no minimum term. For anyone checking more than the occasional property, that's a single low monthly cost for ongoing accredited confirmations - rather than commissioning a separate visit every time a suspect plant appears.

Get KnotweediDFrequently asked questions
Is iD Pro a full Japanese knotweed survey?
No - it's a fast, accredited confirmation from photos, ideal for triage and early certainty. For lending, remediation or a guarantee, a formal on-site survey is still needed. See knotweed, mortgages & house sales.
Who confirms the result?
A PCA CSJK accredited surveyor - the recognised UK mark of Japanese knotweed competence - reviews your photos personally, usually within 24 hours.
Can I share the report with clients or lenders?
Yes. KnotweediD produces a dated report with your photos that you can pass to a client, buyer, solicitor or managing agent as an early, documented record.
How much is iD Pro?
£12.99 a month, cancel anytime - so regular checkers get ongoing confirmations for one low cost rather than paying per property.
This guide is for general information. iD Pro provides an accredited photo-based confirmation, not a formal on-site survey. For a property sale, mortgage application, remediation or legal/boundary matter, always obtain a confirmed on-site survey from a PCA-accredited Japanese knotweed specialist.
