Installing a gas hob may look straightforward, but in the UK it is strictly regulated for safety reasons. This guide answers the most common questions homeowners and landlords ask about gas hob installation, legal requirements, and safety.
Do I Need a Gas Safe Engineer to Install a Gas Hob?
Yes. In the UK, gas hob installation must be carried out by a Gas Safe-registered engineer. Any work involving gas appliances or gas pipework is legally restricted to qualified professionals.

Can I Install a Gas Hob Myself?
No. Installing a gas hob yourself is illegal and unsafe.
Incorrect installation can:
- Cause gas leaks
- Lead to carbon monoxide exposure
- Increase fire and explosion risk
- Invalidate appliance warranties
- Void home insurance policies
How Long Does a Gas Hob Installation Take?
Most gas hob installations take 45 to 90 minutes, depending on:
- Existing pipework condition
- Removal of the old hob
- Accessibility and ventilation requirements
Will a Gas Safe Engineer Remove My Old Gas Hob?
Yes. A Gas Safe engineer can safely disconnect and remove your existing gas hob before installing the new one, ensuring compliance with current regulations.
Do I Need New Gas Pipework?
Not always. If the new hob matches the existing connection and pipework is compliant, no changes may be required. Any alterations must still be carried out by a Gas Safe engineer.
Will the Hob Be Tested After Installation?
Yes. After installation, the engineer will:
- Perform gas-tightness tests
- Check ignition and flame quality
- Confirm ventilation and clearances
- Ensure the appliance is safe to use
What If a Gas Hob Isn’t Installed by a Gas Safe Engineer?
If installed by someone who is not Gas Safe registered:
- The installation is illegal
- Manufacturer warranties may be void
- Home insurance may be invalid
- Serious safety risks are introduced
How do I check if an Engineer Is Gas Safe Registered?
Ask to see the engineer’s Gas Safe ID card and ensure the gas hob installation is listed. You can also verify registration online via the Gas Safe Register.
Is Gas Hob Installation Part of a Gas Safety Certificate?
Landlords usually require gas appliances to be included in annual Gas Safe with CP12 checks. Homeowners will receive confirmation that the hob has been installed and tested safely.
When Should a Gas Hob Be Replaced?
You should consider replacement if:
- Burners fail to ignite
- Flames are yellow or uneven
- You smell gas
- The hob is damaged or outdated
A Gas Safe engineer can advise whether repair or replacement is appropriate.
Are Gas Hobs Safe to Use?
Yes. Gas hobs are safe when installed correctly and properly maintained. Using a Gas Safe-registered engineer ensures compliance, safety, and peace of mind.
