Understanding cooker energy efficiency

Understanding how cookers use energy is the first step towards making an informed choice. Not all cookers are created equal for efficiency, and what appears to be a small difference can add up to substantial savings over time.

The UK energy label system

All new cooking appliances sold in the UK must display an energy label, providing a standardised way to compare efficiency. While many appliances now use a rescaled A-G rating system, ovens and cooker hoods currently use an A+++ (most efficient) to D (least efficient) scale until newer requirements are fully rolled out. These labels help you understand a product's energy efficiency, running costs, and environmental impact. Always check the label before purchasing to ensure you are making an informed decision.

Types of energy-efficient cookers

The type of cooker you choose significantly impacts its energy consumption. Here is a breakdown of common options and their efficiency characteristics:

Induction hobs

Induction hobs are widely considered the most energy-efficient hob type. They work by creating a magnetic field that directly heats the pan, rather than heating the hob surface first, minimising heat loss. This means less heat is lost to the surrounding air, making them incredibly fast and efficient.

• Pros: Very fast, precise temperature control, highly energy-efficient, safer (hob surface does not get as hot).
• Cons: Requires induction-compatible cookware, generally more expensive to purchase.

Electric ovens

Electric ovens are a popular choice, with fan-assisted models often being more efficient than conventional ones. Fan ovens circulate hot air, ensuring more even cooking and often allowing for lower temperatures and shorter cooking times.

• Pros: Even heat distribution (fan ovens), precise temperature control, widely available.
• Cons: Can be slower to heat up than gas, consumes more energy than induction hobs.

Gas cookers

Gas cookers offer instant heat and visual control over the flame. While gas is often cheaper per unit than electricity, the efficiency of gas hobs can be lower than induction due to heat escaping around the pan. Gas ovens can be efficient, but electric fan ovens often outperform them in terms of evenness and speed.

• Pros: Instant heat, good for wok cooking, often cheaper to run per unit of energy (though overall efficiency varies).
• Cons: Less precise temperature control than induction, heat loss from gas flames, requires a gas supply.

Other energy-efficient cooking appliances

Beyond traditional cookers, several smaller appliances can offer significant energy savings for specific tasks:

• Air fryers: Excellent for small portions, roasting vegetables, or making chips. They use convection heating, similar to a fan oven, but in a much smaller, more concentrated space, leading to faster cooking and lower energy use.
• Microwaves: Ideal for reheating, defrosting, and cooking small items quickly. They heat food directly using electromagnetic radiation, making them very energy-efficient for these tasks.
• Slow cookers: Perfect for stews and casseroles, slow cookers use very little electricity over a long period. Their low power draw makes them efficient for dishes that require extended cooking times.
• Pressure cookers: Significantly reduce cooking times for many foods, saving energy compared to conventional hob or oven cooking.

Factors affecting cooker efficiency

Beyond the type of cooker, several habits and factors influence how much energy your cooking consumes:

Pan size and material

Using a pan that matches the hob ring size prevents heat loss. Heavy-bottomed pans retain heat better, reducing the energy needed to maintain temperature.

Preheating habits

Only preheat your oven when absolutely necessary. Many dishes, especially those with longer cooking times, do not require a preheated oven.

Batch cooking

Cooking larger quantities at once can be more energy-efficient than cooking multiple smaller meals, as the oven only needs to be heated once.

Using lids

Covering pots and pans on the hob traps heat and moisture, speeding up cooking and reducing energy consumption.

Minimising oven door opening

Avoid opening the oven door unnecessarily, as each time you do, the temperature can drop significantly, requiring more energy to reheat.

Regular maintenance

Keep your cooker clean. Burnt-on food or grease can affect efficiency.

Practical tips for reducing cooking costs

Making small changes to your cooking routine can lead to noticeable savings on your energy bill. Based on an illustrative electricity unit rate of 26.11p per kWh plus a 57.19p daily standing charge (for a Direct Debit household on the Ofgem price-cap default tariff from 1 July to 30 September 2026), here are some examples:

Choosing the right appliance for the task

Opting for smaller, more efficient appliances like microwaves or air fryers for smaller meals can be more cost-effective than heating a large oven.

Utilising residual heat

Turn off your oven or hob a few minutes before your food is fully cooked; the residual heat will often finish the job.

Defrosting food in advance

Thawing frozen food in the fridge overnight reduces the energy needed to cook it.

Cutting food into smaller pieces

Smaller pieces of food cook faster, reducing the time and energy required.

Considering a smart meter

A smart meter provides the data that helps you track your energy use in real-time via the Fuse app, allowing you to identify peak consumption periods and adjust your cooking habits accordingly.

Conclusion

Choosing the most energy-efficient cooker and adopting smart cooking habits are effective ways for UK homeowners to reduce their household energy costs and environmental impact. From the initial purchase, guided by energy labels, to everyday cooking practices, every decision contributes to a more sustainable and cost-effective home. By understanding the options and implementing these tips, you can enjoy delicious meals while keeping your energy bills in check. This approach to optimising energy use aligns with other home improvements, such as understanding air source heat pump efficiency or considering efficient air conditioning installation for overall home comfort.
