Quick answer
A gas cooker is a gas appliance like any other and should be included in your property’s annual gas safety check, yet it is sometimes overlooked, particularly by tenants and landlords focused mainly on the boiler. Warning signs to watch for include a yellow or orange flame instead of blue, soot marks around the burners, a persistent gas smell, or a pilot light that will not stay lit, any of which are worth having checked by a Gas Safe registered engineer rather than left.
Key takeaways
- A gas cooker or hob is a gas appliance and must legally be included in a landlord’s annual gas safety check, alongside the boiler.
- A healthy gas flame should burn blue and steady; yellow, orange, or flickering flames are a warning sign worth investigating.
- Soot marks or black staining around burners or on cookware can indicate incomplete combustion, which is linked to carbon monoxide risk.
- Any persistent smell of gas near a cooker, or a burner that will not light or stay lit properly, warrants a professional check.
- Only a Gas Safe registered engineer should install, repair, or service a gas cooker; this is not a DIY appliance.
Boilers tend to get most of the attention when it comes to gas safety, understandably given their central role in heating and hot water, but a gas cooker is just as much a gas appliance and deserves the same level of care and attention.
Why cookers are sometimes overlooked
It is a genuinely common oversight, particularly in rented properties, for a gas safety check to focus heavily on the boiler while the cooker receives less attention, sometimes because tenants assume it is checked separately, or because a landlord’s gas safety certificate process was not explicit about including it. Legally, a gas cooker or hob is exactly the same category of appliance as a boiler for the purposes of a landlord gas safety certificate, and it should be explicitly included in the annual check, not assumed to be covered incidentally.
What a healthy gas flame looks like
A correctly functioning gas burner should produce a steady, blue flame, with perhaps a small amount of yellow at the very tip being generally acceptable on some appliances, but a predominantly yellow, orange, or lazy, flickering flame is a genuine warning sign, generally indicating incomplete combustion, which is linked to increased carbon monoxide production. This is one of the more accessible warning signs for a household to notice themselves during normal use, without needing any special equipment, simply by paying attention to flame colour when the cooker is in use.
Soot, staining and other signs
Black soot marks around a burner, staining on the underside of pans that regularly sit on a particular burner, or a build-up of black residue on the appliance itself are all signs worth taking seriously, since they generally point towards the same incomplete combustion issue that produces a yellow or orange flame, and by extension a potential carbon monoxide risk. A persistent smell of gas around the cooker, distinct from the brief smell when first lighting a burner, or a burner that repeatedly fails to light or will not stay lit, are further signs that warrant a professional check rather than continued use.
Servicing and repairs
Only a Gas Safe registered engineer should install, service, or repair a gas cooker, exactly as with any other gas appliance; this is not a job for a general appliance repair technician without the correct gas qualification, and it is certainly not a DIY task. If you are moving into a new property, having a rental cooker checked, or noticing any of the warning signs above, arranging a proper professional check is the appropriate next step.

Frequently asked questions
Does my landlord have to include the cooker in my gas safety check?
Yes, a gas cooker or hob is a gas appliance and should be explicitly included in the annual landlord gas safety check alongside the boiler; if you are unsure whether yours was included, ask to see the certificate.
What does a yellow gas flame mean?
A predominantly yellow or orange flame, rather than blue, generally indicates incomplete combustion and is a warning sign worth having checked by a qualified engineer, since it is linked to increased carbon monoxide production.
Can I service my own gas cooker?
No, gas cooker installation, servicing and repair should only be carried out by a Gas Safe registered engineer; this is not a task for general DIY or a non-gas-qualified appliance technician.
Is it normal for a cooker to smell of gas briefly when lighting?
A very brief smell when first lighting a burner is generally normal, but any persistent or stronger smell is not, and should be treated as a warning sign worth investigating promptly.
What should I do if I notice soot marks around my cooker’s burners?
Stop using the affected burner if you reasonably can, and arrange a check by a Gas Safe registered engineer, since soot marks typically indicate incomplete combustion linked to carbon monoxide risk.
