Registered engineers and businesses must notify new gas installations and safety-critical alterations through the Gas Safe Register or an approved competent-person scheme portal, separately from routine service records. Immediately dangerous situations fall under different rules entirely: some trigger an HSE RIDDOR report without delay, others within 14 days. Mixing up the two routes is one of the most common compliance failures in the trade.
TL;DR:
- Most compliance failures stem from errors like address mismatches or expired insurance, which cause rejection during notification submissions.
- Gas Safe registered individuals and scheme members must verify active registration and current insurance before submitting notifications, as forgotten updates lead to delays.
- Most rejections are due to formatting issues or outdated records, emphasizing the importance of accurate address, appliance, and contact details on file.
- Separating building-regulations notifications from RIDDOR reports is critical; mistakes here can prevent proper incident response or timely danger mitigation.
- Maintaining centralized records, timestamps, and reminder systems reduces errors and ensures continuous compliance for multiple sites or employees.

Which gas works require notification under building regulations
Not every job needs a building-regulations notification. A new gas appliance installation, a boiler swap, or any alteration that changes how a system operates or affects its safety normally needs one. A routine annual safety check, often called a CP12, does not: it is a record of inspection, not a notification of new work.
The legal basis sits in the Gas Safety (Installation and Use) Regulations 1998, which set out installation standards, and in building regulations, which expect local authorities to be informed within a set window after qualifying work completes.
- New installations and appliance replacements usually require notification.
- Alterations that change flue routes, ventilation or appliance type usually require notification.
- Like-for-like servicing or an annual safety check does not require a building-regulations notification.
- Notification and the annual CP12 record serve different purposes and should never be treated as interchangeable paperwork.
Who can submit a notification and what the portals require
Only registered individuals and businesses can notify. Gas Safe registered engineers and firms use the register's own notification route, while members of competent-person schemes, such as those under APHC, can self-certify and notify through their scheme's own portal instead.
Both routes share the same underlying requirement: your registration status, insurance and business details have to be current before the system will accept a submission.
- Confirm your Gas Safe number is active and matches the business submitting the work.
- Check that public liability and professional insurance details on file have not lapsed.
- Verify your scheme membership status if notifying through a competent-person portal rather than Gas Safe Register directly.
- Update your registered address and contact details before attempting a submission, since mismatches are a common rejection cause.
How to submit a building regulations notification
The sequence is broadly the same whichever portal you use, though field names differ slightly between Gas Safe Register and scheme-specific systems such as APHC's.
- Log in with your registered business credentials and select the correct notification type for the work completed.
- Enter the property address exactly as it appears on record, including postcode formatting, to avoid a mismatch flag.
- Record appliance details: make, model, flue type and installation or alteration date.
- Attach your Gas Safe number, business registration reference and insurance confirmation where the form requests it.
- Review the summary screen, submit, and save or screenshot the confirmation reference.
Most rejections trace back to address formatting or an expired insurance record rather than the technical details of the job itself. Keep a copy of the tenant's or customer's preferred contact method on file too, since some notifications ask for it directly.
Pro Tip: Save the confirmation screen as a PDF, not just a screenshot. Portals occasionally time out before sending a confirmation email, and a saved PDF gives you a timestamped record if a notification is ever queried.
Urgent reporting: RIDDOR, HSE and when to flag a dangerous situation
A building-regulations notification and a RIDDOR report answer different questions. Notification tells the authority that work happened. RIDDOR tells HSE that someone was put at risk. Treating one as a substitute for the other is a recurring and avoidable error in the trade.
IGEM's GIUSP guidance classifies dangerous appliances as immediately dangerous (ID) or at risk (AR), and sets out the on-site response for each.
- Isolate or turn off the gas supply where an appliance is immediately dangerous.
- Attach a 'DANGER DO NOT USE' label and leave a signed warning notice with the occupier.
- Photograph the condition and the label placement before you leave site.
- Preserve any removed parts or evidence until the matter is resolved or reported.
Under RIDDOR, HSE must be notified without delay for certain incidents, with other reports due online within 14 days of discovery. Knowing which timeline applies to the incident in front of you matters more than remembering the building-regulations deadline.
Record keeping, tenant copies and the living-document principle
HSE guidance requires landlords to keep gas safety check records for at least two years and treats the record as a living document rather than a one-off form. Issue the record on completion even when defects are found, then supplement it once remedial work closes the issue out.
Tenants have their own deadlines attached to this record.
- Supply existing tenants with a copy of the gas safety check within 28 days of the check.
- Give prospective tenants a copy before they move into the property.
- Deliver records electronically where the tenant has agreed to it, keeping a note of that consent.
- Store originals and remedial updates together so an inspector sees the full history in one place, not scattered documents.
A free landlord gas safety record (CP12) template makes it easier to keep this structure consistent across a portfolio of properties.
Common pitfalls and a short compliance checklist
Most enforcement issues trace back to a handful of repeatable mistakes rather than genuinely difficult judgement calls.
- Check your Gas Safe number and insurance are active before starting the job, not after a portal rejects your submission.
- Confirm the property address format matches local authority records exactly, including flat or unit numbers.
- Photograph danger labels and warning notices on site, with a timestamp, before leaving the property.
- Get a signature on any warning notice left with an occupier, and keep a copy.
- Issue the gas safety record promptly rather than batching paperwork for later, since delayed issuance is itself a compliance gap.
- Log RIDDOR-reportable incidents the same day you discover them, separately from the building-regulations notification.
Running notifications and records inside a service business
Individual engineers can manage one job at a time from memory. A business running several engineers across multiple sites needs a system that does not rely on anyone remembering which notification route applies or when a tenant copy was last issued.
- Assign one person or role as the point of accountability for notification submissions, so nothing falls between two people assuming the other did it.
- Keep a single record per job that ties the CP12 entry, notification confirmation, warning notice and any photographic evidence together under one job reference.
- Use timestamped photos and job logs as standing evidence for warning notices and remedial actions, not just as a one-off file.
- Build renewal and retention reminders into the same system that holds the certificate, rather than tracking expiry dates separately.
A compliance inspection system built around recurring audits and renewal reminders reduces the chance that a notification or a tenant copy gets missed during a busy week.
Why getting notifications right actually matters
Enforcement rarely comes down to one dramatic failure. It comes down to small gaps: a late tenant copy, a notification filed under the wrong route, a warning notice left unsigned. Each one is minor on its own and genuinely dangerous in combination. Treating the checklist in this guide as routine, not optional, is what keeps both tenants and your registration safe.

How Curcle keeps notifications and certificates in one place
We built Curcle around the operational reality that missed notifications usually come from scattered paperwork, not a lack of knowledge. Our platform centralises CP12 and installation records, generates certificates directly from job data, and keeps an audit trail that ties every notification confirmation to the job it belongs to.
- Certificate templates for CP12, EICR, PAT, LOLER and other compliance-led trades sit inside one job record.
- Renewal reminders flag upcoming expiry before a record lapses, not after.
- Exports are built for audit and inspection, so you are not reconstructing history from separate folders.
Our gas-safe engineering software page covers the certificate and notification workflow in more detail, and our pricing page lists current plans, starting with Starter from £99 per month.
FAQ
How long does Gas Safe registration take?
Processing times depend on the application route and the checks required for your qualifications and identity, and are not fixed by a single published figure. Contact the Gas Safe Register directly for current application timelines specific to your trade category.
How long does a gas safety check take in the UK?
Duration varies by property size and the number of appliances being checked, so no single figure applies across the board. An engineer carrying out the check on site is best placed to give you a time estimate for your specific property.
How do I check if someone is on the Gas Safe Register?
You can search the Gas Safe Register directly using an engineer's licence number or business name to confirm current registration status. Always check this before any gas work begins, since unregistered work is illegal and uninsured.
How do I get a Gas Safety Certificate in the UK?
A registered Gas Safe engineer must carry out the check and issue the certificate, commonly known as a CP12, on completion. Landlords must then supply a copy to existing tenants within 28 days and to prospective tenants before they move in, as set out in HSE guidance.
What counts as suspect or illegal gas work?
Unregistered individuals carrying out gas work, or installations that bypass safety checks entirely, can be reported through the Gas Safe Register's reporting flow. This is separate from a RIDDOR report and is used specifically to flag unregistered or potentially dangerous work to the register itself.
