Domestic CP12 and commercial gas safety. Gas Safe-aligned certificates.
Manage gas safety inspections and records: appliance checks, flue testing, tightness tests and Gas Safe-aligned certificates.
The duty
What Gas Safety compliance involves.
The Gas Safety (Installation and Use) Regulations 1998 require gas appliances and flues to be maintained in a safe condition and, for rented property, checked every 12 months by a Gas Safe registered engineer.
CertFlow schedules annual checks, captures appliance and flue results in the field, and outputs Gas Safe-aligned records ready to hand to landlords and tenants.
Your legal duties
What the regulations require.
Annual gas safety check (rented property)
Landlords must ensure gas appliances, fittings and flues in rented property are checked for safety every 12 months by a Gas Safe registered engineer, and give the tenant a copy of the record.
Maintenance in a safe condition
Gas appliances and flues must be maintained in a safe condition. Any work on gas fittings may only be carried out by a Gas Safe registered engineer holding the right qualifications for the appliance.
Commercial gas safety
In commercial premises, gas plant and catering appliances must be installed, tightness tested and maintained to the relevant standards, with safety records kept for each appliance.
Records
Gas safety records must be kept. For rented property the landlord must retain records and issue the latest one to tenants within the required timescale.

Every gas safety certificate is filed in a searchable, exportable compliance registry with a full timestamped history.
From the field
What inspectors commonly find.
The defects and gaps that come up again and again on gas safety inspections, the ones a good system helps you catch before an auditor does.
- Work carried out by an engineer not Gas Safe registered for that appliance type
- Inadequate flue, ventilation or combustion air provision
- Gas tightness and combustion performance not properly tested
- Safety devices defeated, bypassed or not working
- Landlord gas safety records missing, overdue or not issued to tenants
Why it matters
Penalties & enforcement.
Breaches of the Gas Safety (Installation and Use) Regulations 1998 are a criminal offence. They can bring HSE prosecution, unlimited fines and imprisonment, and carry a real risk of gas explosion or carbon monoxide poisoning.
