When the insurer asks for proof, have it ready.
Built-up grease in commercial-kitchen extract ducts is a leading cause of kitchen fires — and a gap in your cleaning records is a gap in your defence. VentReport documents and proves your ducts were cleaned to EN 15780:2025 Annex J — the European standard for grease-duct cleaning — and hands you a sealed, tamper-evident report you can produce in seconds for any inspector, insurer or landlord.
It captures the inspection on site (even with no signal), checks every reading against the standard automatically, and is free to try, with no credit card.

What VentReport does
EN 15780 Annex J sets measurable cleanliness limits — grease-film thickness in micrometres — and a strict list of what every inspection and clean must record. VentReport turns that into a guided digital workflow.
Capture on site — even offline
Record readings and photos at the required sampling points on a phone or tablet, with big tap targets for gloved, one-handed use on rooftops and in plant rooms. Can't safely reach a duct? Mark it inaccessible with a reason (J.15) and still finalise the report. Nothing is ever lost: every reading and photo is saved to your device the instant you capture it, and uploads automatically once you're back online.
Automatic pass/fail against the standard
Every reading is scored against EN 15780's own limits (Table J.1) automatically — no mental maths on a ladder, no guessing on a borderline reading. The data is judged against the standard, not simply asserted.
Reports generated for you, in your language
A professional cleaning report in minutes, in the user's own language — not a half-day rebuilt by hand. The technician who did the work is named on it, so it's clear who certified it.
Sealed and tamper-evident
A finished report is sealed with an electronic seal and a trusted timestamp, so any later change is detectable and its authenticity and date can be verified independently — exactly what insurers, auditors and fire inspectors look for.
Next-due dates, per site
VentReport learns how fast grease rebuilds at each site, projects the next-due date from that site's own history, and reminds the responsible people before a clean falls overdue — not a fixed, one-size-fits-all interval.
One dashboard, at a glance
A red / amber / green status for every site, so a lapse surfaces to the people responsible instead of staying silent.
History that stays with the building
The record is attached to the site, not the cleaning firm — change contractors, managing agents or owners and nothing is lost.
Shareable proof
Send a sealed report to an inspector, insurer or landlord with a single link — no app for them to install.
Who VentReport is for
One shared record — each party sees only the view that fits their job.
Cleaning contractors
- Fast on-site capture that works without signal — no transcribing notes in the evening.
- Reports generated for you, so your deliverable looks as serious as your work.
- A sealed audit trail that helps you win and keep contracts.
- Set up a site and produce your first sealed report the same day — no migration project.
Facility managers
- Your contractors capture on site; results flow straight to your dashboard — you enter nothing.
- Red / amber / green status, automatic next-due dates and overdue reminders — stop chasing paperwork.
- A record that stays with each site, so you see its real state on day one of a new property.
Property owners
- Defensible, tamper-evident proof your ducts were cleaned to standard — protection in insurance and liability disputes.
- A compliance history that stays with the building even when contractors change.
- See a lapsing clean before it becomes a gap in your defence.
Restaurant & kitchen operators
- Simple, shareable proof — forward a sealed link in seconds, no app to install.
- Your records stay with you even if you change cleaning firms.
- No new burden: your contractor typically runs the account, and you only ever see your own site.
Insurers
- A credible, tamper-evident compliance record for underwriting and claims — its authenticity and the date it was issued can be verified independently.
- Proof arrives as a single shareable link, scored against the standard — no chasing customers for paperwork.
Authorities
- Consistent, standard-based documentation that's quick to inspect against EN 15780.
- A clear audit trail — every reading scored against the standard, plus who did the work and when.
Why a VentReport record holds up
- Judged, not asserted. Readings are scored against the standard's own thresholds, so an inadequate clean shows amber or red instead of quietly passing.
- Locked once sealed. After the seal and timestamp, any later change is detectable — and a third party can confirm it's genuine and dated without taking anyone's word for it.
Built around how EN 15780 Annex J actually works — the sampling locations, the rules for ducts that can't be reached, grease-film readings in micrometres — not a generic checklist with the standard's name on it.
How your data is kept safe

What is EN 15780:2025 Annex J grease-duct cleaning?
EN 15780:2025 Annex J is the European standard that sets measurable cleanliness limits — grease-film thickness in micrometres — and a required set of records for cleaning grease-extract ductwork in commercial kitchens. It defines how clean the ducts must be and exactly what each inspection and clean must document. VentReport is built to follow it, point for point.
Frequently asked questions
What is VentReport?
VentReport is a web and mobile app for documenting and proving that commercial-kitchen grease-extract ducts have been cleaned to EN 15780:2025 Annex J. It captures inspections, grease-film readings and photos on site, scores them against the standard automatically, and produces a sealed, tamper-evident compliance report.
What is grease-duct cleaning compliance, and why does it matter?
Grease-duct cleaning compliance means a commercial kitchen's extract ductwork has been cleaned to a measurable standard, and that this is properly documented. It matters because built-up grease in kitchen extract ducts is a leading cause of commercial-kitchen fires — and without a credible record, property owners and operators can be exposed in insurance claims, liability disputes and fire inspections.
Does VentReport work offline?
Yes. You can capture grease-film readings and photos on site with no signal — for example in a plant room or on a rooftop — and the data is saved on your device immediately and syncs automatically once you're back online.
Is a VentReport report legally valid proof of compliance?
A finished VentReport report is sealed with an electronic seal and a trusted timestamp, so any change after signing is detectable and its authenticity and date can be verified independently. Whether a specific insurer, landlord or fire authority accepts a given document depends on their own requirements; VentReport gives you a record built to be defensible and easy to hand over.
What measurement method and units does VentReport use?
VentReport uses the WFTT (wet film thickness test) — a technician reads the grease film on the duct surface with a gauge — and records it as grease-film thickness in micrometres, at the sampling locations EN 15780 Annex J requires. Each reading is then scored automatically against the standard's pass/fail thresholds.
What are the EN 15780 Annex J cleanliness thresholds?
EN 15780:2025 Annex J (Table J.1) sets grease-film limits in micrometres (µm). Before cleaning, a system reaches its limit at a 200 µm mean across the measured points, or 500 µm at any single point; after cleaning, every point must read below 50 µm. VentReport scores each reading against these limits automatically.
How many sampling locations does EN 15780 Annex J require?
It defines nine sampling locations — eight set out in the standard (labelled a–h) plus one user-defined location — so readings are taken consistently across the duct system. VentReport guides the technician through each required point, and lets them mark any that can't be safely reached, with a reason.
How does VentReport calculate when the next cleaning is due?
VentReport projects each kitchen's next-due date from how quickly grease re-accumulates at that specific site — measured from its own inspection history — and reminds the responsible people before a clean falls overdue, rather than applying a fixed one-size-fits-all interval.
What happens to my compliance records if I switch cleaning contractors?
Nothing is lost. The compliance history is attached to the building, not the contractor, so the full inspection-and-cleaning record stays with the site through a change of cleaning firm, managing agent or building owner — and so does your access to it.
Who is VentReport for — the cleaning contractor or the building owner?
Both, on one shared record. Cleaning contractors capture the data, facility managers coordinate, property owners hold the defensible proof, and restaurant operators get shareable confirmation. Each role sees only the view relevant to them.
Is VentReport free to try?
Yes — you can start using VentReport for free, with no credit card. Set up a site, run an inspection, and generate your first sealed report to see how it fits your workflow. Talk to us when you're ready to roll it out across more sites.
Where is my data stored, and is VentReport GDPR-compliant?
All compliance records and personal data are stored and processed in the EU, encrypted in transit and at rest, with each customer organisation isolated so it only ever sees its own data. VentReport is built GDPR-first: a data-processing agreement is available on request, the sub-processor list is published openly, and the right to erasure is honoured.
What languages does VentReport support?
VentReport is available in English and Swedish, and generates cleaning reports in the user's own language. We add languages over time.
