If you own a gas oven, you might assume it runs entirely on gas. In reality, most modern gas ovens also use electricity to power features such as ignition systems, timers and safety controls. However, some models can still operate during a power cut, depending on their design and ignition type.
Understanding which functions rely on electricity can help you choose the right appliance for your kitchen. Whether you’re considering a traditional gas oven or exploring dual fuel options, this guide explains everything you need to know.
Do Gas Ovens Use Electricity?
Yes, most modern gas ovens use electricity for several key functions. Gas provides the heat. Electricity runs almost everything else.
Here’s what depends on your electrical supply:
- Electronic ignition – sparks the gas burner to life
- Digital display and controls – temperature setting and timers
- Interior oven light – so you can see inside
- Convection fan – for fan-assisted cooking modes
- Safety valve – prevents gas flow without a confirmed ignition
Without electricity, most of these stop working. In many models, the safety valve won’t open at all.
Can You Use A Gas Oven Without Electricity?
For older gas oven models with a standing pilot light, you can use them without electricity. For most modern gas ovens, no.
Modern gas ovens use electronic ignition. Without power, the igniter can’t spark. Even if you manually introduce a flame, many models include an electric safety interlock that blocks gas flow unless ignition is electronically confirmed.
The hob is different. Some gas hobs allow manual lighting with a match or long lighter, but always check your manual first. The oven itself is rarely safe to light manually.
What Is An Electric Gas Oven?
An electric gas oven combines a gas hob with an electric oven.
It gives you the best of both fuels:
- Gas hob: instant heat, precise flame control
- Electric oven: even heat distribution, better temperature accuracy
- No pilot light required, so the oven ignites electronically
Many professional chefs prefer gas hobs with electric ovens for exactly this reason, the control of gas above and the consistency of electric below.
One thing to note: electric gas ovens require both a gas connection and a mains electrical supply. Installation must be carried out by a Gas Safe registered engineer.
How Much Electricity Does A Gas Oven Use?
Gas ovens use only a small amount of electricity to power features such as the igniter, interior light, cooling fan and digital display. The main source of cooking energy still comes from gas, which is often one reason why gas ovens can be more economical to run in the UK.
| Appliance Type | Main Energy Source | Typical Electricity Usage | Average Cost Per Hour |
| Gas Oven | Gas | 1.5 kWh (Low electrical usage for controls and ignition) | ~13.21p |
| Electric Oven | Electricity | 1.0-1.5 kWh (Fully powered by electricity) | ~55.35p |
While exact costs vary depending on energy prices and cooking habits, gas is generally cheaper per kWh than electricity in the UK. This can make gas ovens a cost-effective option for households that cook frequently.
Are Gas Ovens Still Common In The UK?
Yes, gas ovens are still common in the UK. Though the balance is shifting. Gas hobs are currently installed in around half of all UK homes (CLASP, 2026). Gas ovens made up around 39% of cooker sales in recent years, (MECS, 2024).
The government has outlined plans to phase out gas in new homes, with Parliament’s Climate Change Committee recommending a gas cooker phase-out by the mid-2030s. For now, gas ovens remain a mainstream, practical choice.
Single Gas Oven Or Dual Fuel: Which Is Right For You?
Choosing between a single gas oven and a dual fuel model depends on your priorities:
- Single gas oven: lower purchase cost, straightforward installation, suits those already on gas
- Dual fuel (electric oven with gas hob): better baking results, more features, suits those who want flexibility
If you bake regularly, a single gas oven may produce less consistent results than an electric alternative as gas heat rises unevenly. For roasting and everyday cooking, it performs well.
How Do You Know If Your Gas Oven Has A Fault?
Electrical faults and gas issues can both affect oven performance. Knowing the warning signs saves time and prevents safety risks.
Signs something may be wrong:
- If the igniter clicks repeatedly but the oven won’t light, this is often an electrical or igniter fault
- If the oven takes much longer to reach temperature than usual, it could be a failing thermostat
- Uneven, yellow or orange flames are irregular, normal gas flames should be blue
- If you smell gas when the oven is off, turn off the supply and call a Gas Safe engineer immediately
- If the digital display is blank or unresponsive, check the mains connection first
Never attempt to repair gas components yourself. In the UK, all gas work must be carried out by a Gas Safe registered engineer. For electrical faults on the oven, a qualified electrician should assess the appliance.
Regular servicing keeps your gas oven running safely and efficiently. An annual check is recommended, particularly important if you notice any change in performance.
Key Things To Know Before Buying A Gas Oven
- All gas oven installations in the UK must be completed by a Gas Safe registered engineer.
- Check whether your model includes an electronic safety interlock (most modern ovens do).
- By installing a cooker hood or ceiling hood, you’ll ensure your kitchen has adequate ventilation. Gas cooking releases NO₂ and CO₂, which can contribute to respiratory risks over prolonged exposure.
- Dual fuel models need both a gas supply and a suitable mains electrical socket.
