Common Gas Safety Issues We Identify
At Landlord Sure, our Domestic Gas Safety inspections are designed to identify gas safety issues that could affect the safe operation of appliances and installations. Our Gas Safe registered engineers inspect gas appliances, flues, pipework, ventilation, and associated safety components within the property.
During the inspection, we commonly identify issues such as unsafe appliance operation, inadequate ventilation, flue problems, signs of gas leakage, damaged pipework, incorrect appliance installation, poor combustion, and missing or unsuitable safety provisions. Each relevant appliance is checked carefully and the findings are recorded within the Gas Safety Record.
Following the inspection, any safety concerns are clearly explained, with appropriate recommendations where further investigation, repair, or remedial work is required. This helps landlords, letting agents, and property managers maintain safe gas installations and meet their gas safety responsibilities.

Landlord Gas Safety Certificate: Your Legal Duties
Under the Gas Safety (Installation and Use) Regulations 1998, landlords must make sure every gas appliance, fitting and flue they provide is safe. In practice this means you must:
- have a gas safety check carried out every 12 months by a Gas Safe registered engineer
- give a copy of the landlord gas safety record (often called a CP12) to existing tenants within 28 days of the check
- give new tenants a copy before they move in
- keep a copy of each record for at least two years
- make sure appliances are maintained in a safe condition between checks
Letting agents who manage gas safety for a landlord share these duties, so it is important that responsibilities are agreed in writing.
What Is Checked During a Gas Safety Inspection?
- gas tightness of the installation and pipework
- burner pressure and gas rate against the manufacturer's data
- flues and chimneys, to make sure fumes are removed safely
- ventilation and air supply to each appliance
- safety devices, such as flame failure devices, working correctly
- boilers, gas fires, gas cookers and hobs supplied by the landlord
Appliances owned by tenants are not covered, but the engineer will check the pipework that supplies them.
How Much Does a Gas Safety Certificate Cost in London?
Our landlord gas safety certificates start from £55, as shown in the pricing plans above. The price depends mainly on the number of gas appliances, plus any extra services you add, such as a boiler service or an EICR at the same visit. There are no hidden call-out charges.
Can I Renew My Gas Safety Certificate Early?
Yes. Since April 2018, landlords can have the annual check carried out up to two months before the current record runs out and keep the original expiry date. This makes it easier to arrange access with tenants without shortening the 12-month cycle.
What Happens If an Appliance Fails?
| Classification | What it means |
|---|---|
| Immediately Dangerous (ID) | The appliance poses an immediate risk. With your permission it will be disconnected and labelled until it is repaired. |
| At Risk (AR) | One or more faults could become dangerous. The appliance is usually turned off and must be repaired before it is used again. |
| Not to Current Standards (NCS) | The appliance is safe to use but does not meet current standards. Upgrading is recommended. |
We explain any defects clearly and can quote for repairs so you can get a valid certificate quickly.
Gas Safety Check vs Boiler Service
A gas safety check confirms that appliances are safe to use. A boiler service is maintenance that keeps the boiler working efficiently and is often needed to keep a warranty valid. They are different, but many landlords book both at the same visit to save time and keep tenants happy.

Our inspection checks relevant gas appliances, flues, ventilation, pipework, gas pressures, combustion, and safety controls to identify conditions that may require attention.
Who needs a Gas Safety Certificate?
