The mistakes clients write back about.
Every check began as a complaint about a real report. Clients now paste reports into ChatGPT and send back what it finds. StackProof finds it first.
On top of the rules, an AI review reads the report against itself and against public records for the property (energy certificate, listing, flood risk), then checks spelling, placeholders and drafting notes left for the valuer.
- Sections that disagree
The same thing described two ways in one report: roof covering, boiler fuel, damp, air bricks, gutters, drainage, chimney breasts, extractor fans.
D4: “No evidence of dampness.” E4: “Dampness was recorded.”
- A limitation, then a conclusion
A roof space not entered, but its insulation called adequate. A manhole not lifted, but no blockage found. A stopcock not located, but in reasonable condition.
“The stopcock could not be located. It appears to be in reasonable condition.”
- Carried over from the last report
Another property’s address, postcode or client, the wrong storeys or bedrooms, features this property does not have, and another firm’s name, phone number or liability wording.
“Westbrook Surveyors accepts no responsibility to third parties.”
- Valuation figures and dates
Figures in words that differ from the number, malformed sums, freehold in one section and leasehold in another, comparables that do not add up, and a CGT or probate valuation dated only at the inspection.
“£530,000 (Five Hundred and Forty Thousand Pounds).”
- Ratings and costs
An element rated 1 in the summary and 3 in the entry, a 1 on something that could not be seen, and repair costs for work no element mentions.
Costs: “Moss clearance, £450.” D2 is rated 1 and never mentions moss.
- Your firm and your surveyor
Your RICS firm number and the signing surveyor’s name, qualifications and RICS number, checked against the details you set up.
“A. Patel BSc MRICS MFPW”, where your records say MFPWS.
Draft to sign-off in three steps.
1
Drop in the report
PDF or Word: Level 2, Level 3, valuation, CGT, probate, rent review. It is read in your browser and only the text is sent for checking.
2
Work through the marks
Each one links to its paragraph. Mark it fixed, not an issue or unsure, edit the wording in place, and export a corrected Word file.
3
Mark it final
The final is compared with the first draft and a QA record goes to your admin. Checks your firm always waves through get quieter.
Proof your reports were checked, and that AI was used properly.
Since 9 March 2026 the RICS standard on the responsible use of AI applies to every member and regulated firm. StackProof is built to sit inside it, and keeps the paper trail your PI insurer and RICS ask for.
- A record for every report
- What was checked, which flags were raised, and each surveyor’s call on them.
- The surveyor decides
- Every AI flag is a suggestion. StackProof never edits a report on its own.
- Wording you can use
- Ready text for your AI register and your terms of engagement.
- No training on your reports
- Report text is never used to train AI models, and is deleted once the draft and final are compared.
Less than one reissued report.
Five reports free, no card needed. Then monthly, cancel any time.

What firms ask first.
- Does StackProof change my report?
- No. It flags, and your surveyor decides. You can edit a paragraph in StackProof and export a corrected Word file, or make the changes in your own copy.
- Will my clients see it?
- No. StackProof is for your team. Nothing in it reaches the client, and it never adds anything to the report.
- Which reports does it check?
- RICS Level 2 and Level 3 surveys, building surveys, specific defect reports, market valuations, Help to Buy, CGT, probate and matrimonial valuations, and rent reviews. PDF or Word.
- Is my clients’ data used to train AI?
- No. Report text goes to the AI review under terms that do not allow training on it. The text is held only until the draft and the final are compared, then deleted. The flags and your calls are kept as your QA record.
- How are the five free reports counted?
- By property. Checking a revised draft or the final of a report you have already checked does not use another one.
- We already use SurveyStack. Do we pay again?
- No. StackProof is included in SurveyStack plans, and can stop a report reaching the client until it has been checked.
