Prove every gas appliance
is in date.
UK law requires landlords and property managers to ensure every gas appliance is safe and properly maintained. QR-Inventory turns each appliance into a self-evidencing record — the current certificate, the next inspection date and a tamper-evident history, one scan away.

A missing certificate is a missing defence.
UK law requires landlords and property managers to ensure all gas appliances are safe and properly maintained — in holiday lets, private rentals, commercial properties and residential accommodation alike. The duty is annual, dated and evidenced. When a tenant, a guest, an insurer or an inspector asks to see the current certificate, a folder of scanned PDFs or a shared drive isn't evidence — it's a liability. Spreadsheets don't survive an audit.
Mapped to the annual gas safety cycle.
Every gas appliance needs a competent inspection each year, a certificate that records the result, and documentation that the people using the property can actually reach. Here's where QR-Inventory does the heavy lifting.
The annual inspection, scheduled
Every appliance carries its own annual cadence and its own CP12. Reminders reach the engineer, the admin team or the property manager 30, 60 or 90 days before expiry, and anything overdue surfaces on a live dashboard — so a lapsed certificate becomes impossible, not just unlikely.
The certificate, one scan away
Tenants, guests and inspectors scan the tag beside the appliance and see the current certificate immediately — no login, no email chain, no request to the office. Perfect for holiday lets, where reassurance has to be instant, and for rentals where tenants are entitled to the documentation.
Certificate upload & storage
Upload the certificate against the appliance itself. Once it's there, anyone who scans the tag sees the current version — never a superseded copy.
Inspection reminders
Notify engineers, admin staff or property managers 30, 60 or 90 days before a certificate expires, so continuous compliance is the default.
Engineer access
Give gas engineers labels and system access so they can apply stickers, register appliances and upload certificates in one streamlined visit.
Expiries you can't miss
An expired certificate is shown as expired the moment the tag is scanned, and the reminder escalates until the appliance is re-inspected.
Compliance reporting
Report gas safety status across every property you hold, with a complete audit trail of inspections, renewals and engineer visits.
Captured on site
Engineers and property managers upload from a phone while they're still at the appliance, so the record is written before they leave.
QR-Inventory produces the defensible record that proves your gas safety inspections happened. It does not, by itself, make a property compliant — the inspection must be carried out by a competent engineer, and your gas safety scope and duties should be confirmed with them. UK law requires annual gas safety inspections of the gas appliances in rented accommodation.
An unbroken record, written as it happens.
Nothing is editable after the fact. Every inspection, certificate and defect is appended, attributed and sealed — so the gas safety history you hand to a tenant, an insurer or an inspector is the history that actually happened.
Tamper-evident by design
Each entry is hashed and chained to the last. Any alteration is detectable.
Time-stamped & attributed
Who, what, where and when — captured automatically at the point of scan.
Defensible in any inspection
Export a complete, signed evidence pack for a single appliance or your whole portfolio.
CP12 — annual inspection
Every certificate, every appliance — findable in seconds.
No more lost paperwork and no more hunting through email for last year's certificate. A record is generated against every inspection, attached to the appliance, and superseded — never deleted — when it is re-issued. The full history stays one scan away.
- Auto-generated certificate record per appliance, versioned
- Defect → ticket → re-inspection loop, closed and logged
- Expiry reminders to the landlord, agent and engineer
- Bulk evidence-pack export for insurers, auditors and agents
Tag it. Inspect it. Prove it.
The appliance becomes the front door to its own certificate — no logins to hunt for, no folder to find.
Scope & tag
Book a scoping call and we'll map QR-Inventory to your appliances, set up your account and send tamper-evident QR labels for every boiler, fire, cooker and gas fitting.
Inspect
The engineer scans the appliance, completes the safety inspection and uploads the certificate from a phone — no trip back to the office to file paperwork.
Prove
Tenants, guests and inspectors scan to see the current certificate, and reminders fire long before it expires — for one property or the whole portfolio.
