Repair your gas hob.

Most gas hob issues are repairable, often proving more cost-effective than a full replacement. This guide outlines the costs, timeframes, and essential safety regulations you need to know before booking a Gas Safe engineer.

What Does the Work Involve?

• Initial Safety Inspection: Checking the hob burners, ignition systems, and visible gas connections for signs of wear or damage.
• Gas Tightness Test: Performing a formal pressure test on the gas supply to ensure there are no leaks within the appliance or the internal pipework.
• Burner Servicing: Removing and cleaning burner heads, jets, and caps to ensure a clean, blue flame and efficient combustion.
• Component Replacement: Swapping out faulty thermocouples, spark generators, ignition electrodes, or control valves.
• Final Safety Check: Re-testing the appliance operation and providing a Gas Safe record or job sheet for your home maintenance files.

Typical Costs

Prices for gas hob repairs vary based on your location in the UK and the specific parts required. High-end brands like Miele or Wolf may incur higher component costs and specialist labour rates.

If your hob is over 10-12 years old and requires multiple parts, your engineer may advise that a full replacement is more economical. Always factor in the cost of a new "Gas Safety Certificate" if you are a landlord or selling your property.

How Long Does It Take?

• Minor Repairs (Cleaning/Adjustments): 30 to 60 minutes.
• Common Part Replacement: 1 to 2 hours, assuming the engineer has the part on their van.
• Complex Faults/Sourcing Parts: 2 to 4 hours over two visits (one for diagnosis, one for fitting).
• Full Hob Replacement: 1.5 to 3 hours, including the removal of the old unit and sealing the new one.

DIY or Professional?

In the UK, it is illegal for anyone other than a Gas Safe registered engineer to carry out work on a gas appliance for hire or reward. While you can safely clean the burner caps and pan supports yourself, you must never attempt to disassemble the gas valves or pipework.

Any work involving the gas supply, thermocouples, or internal ignition wiring must be performed by a professional to ensure your home insurance remains valid and your family stays safe.

Choosing the Right Tradesperson

• Check the Register: Always verify their Gas Safe ID card and check the back of the card to ensure they are qualified for "Cookers" and "Hobs."
• Specialism: Ask if they have experience with your specific brand, particularly for premium German or Italian appliances.
• Transparent Pricing: Ensure they provide a breakdown of the call-out fee versus the hourly rate and whether VAT is included.
• Questions to Ask:
  • Are you Gas Safe registered and can I see your ID?
  • Does the quote include a gas tightness test?
  • What is the warranty period for the replacement parts?
  • If the hob is beyond repair, what is your fee for the diagnostic visit?

UK Regulations

• Gas Safety (Installation and Use) Regulations 1998: The primary legislation governing all gas work in the UK.
• Part P (Electrical Safety): Relevant if the engineer is working on the integrated electric ignition system.
• Landlord Obligations: If you rent out your property, you must have a CP12 certificate issued annually, which includes checking the hob.
• Ventilation Standards: Engineers must check that your kitchen has adequate ventilation (air bricks or windows) as per current Building Regulations.

Common Problems

• Burner won't stay lit: This is almost always a faulty thermocouple, which fails to detect the heat and shuts off the gas for safety.
• Constant clicking: Usually caused by moisture in the switches after cleaning or a faulty ignition microswitch.
• Orange/Yellow flame: Indicates incomplete combustion, often caused by blocked jets or a lack of oxygen; this can produce dangerous carbon monoxide.
• Gas smell when off: A serious issue indicating a leak in the control valve or the supply pipework; turn off your gas at the meter immediately.
