It is often worth fixing a gas cooker if the cost of repairs does not exceed 50% of the price of a new oven.

Gas oven repairs are generally not worth the cost if the following apply:

• The appliance is over ten years old

• There are signs of leaking gas

• There is a weak yellow flame (the flame should be blue)

• Several replacement parts are needed

Over repair work can be more budget-friendly in the short term but it’s not always the most cost-effective solution.

The costs of repeatedly hiring a Gas Registered engineer to keep fixing a faulty oven can quickly add up. The average gas oven installation price is £275, whereas fees for professional repairs can cost between £100 - £300.

In most circumstances, the choice of whether to replace or repair a gas cooker is determined by the appliance’s age and condition. You can also read our oven repair cost guide for a closer look at current average prices.

A faulty gas oven can be dangerous. If your oven won’t light, fails to heat up, or has a bad odour, there is likely a problem that needs to be fixed.

We recommend following these steps if your gas cooker is not working correctly:

• Check the gas supply - Your oven will not light if the gas supply is turned off or is not working correctly. A foul rotten eggs smell is a sign of a gas leak and you should turn the gas supply off as soon as possible

• Check the flame - A gas oven should have a strong blue flame when switched on. There is likely a problem with the flame failure device (FFD) if the flame is yellow. A dirty or a damaged FFD will stop your oven from heating up correctly

• Call a Gas Safe engineer - A registered Gas Safe engineer can diagnose various oven faults and provide any repairs needed

Above anything else, it is important to always shut off the gas supply and ventilate your home if you smell leaking gas.

All gas engineers working in the UK must be registered with the Gas Safe Register. Tradespeople providing gas oven repairs without being registered are breaking the law.

Follow these simple steps to check if a gas engineer is registered:

• Ask to see their Gas Safe ID card. This card will have the tradesperson picture and an expiry date on the front. On the back you will find details of jobs the engineer can carry out, such as gas oven repairs and boiler servicing

• Verify an engineer's registration by entering the number on their ID card or their name into the Gas Safe Register website’s search tool

Unlike being Gas Safe registered, it is not a legal requirement for gas engineers to be insured. For total peace of mind, however, we recommend only hiring tradespeople with up to date insurance cover. Hiring an uninsured gas engineer in London can be risky and lead to potential financial disputes in the future.

The majority of reputable gas engineers will have the following types of insurance:

• Public liability insurance

• Product liability insurance

• Professional indemnity insurance

Follow these simple steps to make sure you are hiring a reputable engineer to repair your damaged gas cooker:

• Ask friends and family for recommendations of local Gas Safe registered engineers. Check a tradesperson works to a high quality standard by searching for them in the Checkatrade directory

• Read customer reviews and check the repair company or engineer’s online ratings. We make sure all reviews published on Checkatrade have been written by real people

• Ask questions. Make sure to ask a gas engineer for details of their qualifications, experience, and insurance. It is also essential that you make sure they are Gas Safe registered by asking to see their ID card

• Ask if their work is covered by a guarantee. Hiring a guaranteed tradesperson will provide you with extra peace of mind and protection should anything go wrong. We guarantee the work of our approved members up to £1,000 for 12 months - eligibility criteria and T&Cs apply
