When it comes to upgrading your kitchen appliances, swapping out your old gas hob for a sleek electric one might seem as simple as “just plugging it in.” However, it turns out that making the switch isn’t always quite that straightforward. Before diving in, it’s crucial to understand the implications, particularly when it comes to electrical power requirements and the potential need for an electrical upgrade.

The Power Demands of Electric Hobs

Electric hobs, especially modern induction or ceramic hobs, are known for their powerful heating capabilities, efficiency, and sleek design. But, their benefits come at the cost of increased power demand compared to most gas units. A typical electric hob requires a dedicated high-power electrical connection due to the substantial current draw, which can range from around 20 to 45 amps, depending on the model.

A Common Misconception: Just Plugging It In?

Unlike small kitchen appliances like toasters or microwaves that plug into a standard 13-amp socket, an electric hob often cannot simply be plugged into a regular outlet. Here’s why:

• High Current Demand: An electric hob running at maximum capacity with all rings on can demand significant amounts of power, up to 7-10 kW in some models. That is well beyond the typical 2.4kW limit of a standard UK socket.
• Electrical Circuit Requirements: Most electric hobs need to be hardwired into a dedicated circuit, typically using 6mm² or even 10mm² cable depending on the required load. This circuit is connected directly to the consumer unit (fuse box) with its own breaker.

Comparing Power Usage: Electric Hob vs. Other Kitchen Appliances

To understand the power demands better, here’s a look at the approximate power usage of common kitchen appliances compared to an electric hob:

• Electric Oven: Typically draws between 2-5 kW depending on its size and features.
• Microwave: Generally uses around 0.6-1.2 kW.
• Toaster: Around 0.8-1.5 kW.
• Kettle: Approximately 2-3 kW.

From this comparison, it’s clear that an electric hob can draw more power than most other kitchen appliances combined, especially if multiple rings are used simultaneously.

Electrical Upgrades May Be Necessary

If your home currently has a gas hob, there’s a good chance that your electrical setup was not designed to accommodate the substantial power demand of an electric hob. Some common upgrades you might need include:

1. Dedicated Circuit: Running a new dedicated circuit with an appropriate cable size to safely handle the load of the hob.
2. Consumer Unit Upgrade: In some cases, an older consumer unit may need to be replaced or upgraded to support the new load requirements, adding an extra layer of safety to your electrical system.
3. Professional Assessment: It is highly recommended to have a qualified electrician perform a survey before you purchase a new electric hob. They can determine if your current setup is sufficient or if modifications are required.

A Costly Surprise?

It’s common for homeowners to be surprised by the additional costs involved when upgrading to an electric hob. The expense of rewiring, consumer unit upgrades, and other necessary modifications can sometimes exceed the cost of the hob itself. While an electric hob can be a valuable addition to your kitchen, it’s important to be prepared for potential extra expenses and ensure a safe installation.

Final Thoughts

Switching from a gas to an electric hob can elevate your cooking experience, offering improved efficiency and modern aesthetics. However, unlike smaller appliances, it’s not always as simple as plugging it in. Before making the switch, consult with a professional electrician to assess your home’s electrical system and determine if it can safely handle the power demand of a new electric hob. This proactive step could save you both money and headaches, and most importantly, ensure the safety of your kitchen.
