Cooker Switches

Getting your kitchen set up safely is just as important as choosing the right appliances. Cooker switches can seem like a small detail but they play a big role in everyday use and emergency situations. Below, we’ve answered the most common questions so you can understand what they do, whether you really need one and the best place to install it.

 

What is a cooker isolation switch?

A cooker isolation switch is a high capacity switch that lets you quickly cut the power to your oven or hob, without turning off your whole kitchen. It’s designed to handle the higher energy demand of cooking appliances, and you’ll often see it as a bold red switch placed somewhere easy to reach. This means if you need to carry out maintenance, make repairs or switch the cooker off in an emergency, you can do it instantly and safely.

 

Is it a legal requirement to have a cooker switch?

No, it’s not a strict legal requirement to have a cooker switch in every kitchen. There’s no specific regulation in BS7671 that says you must install one, and building regulations only offer guidance rather than hard rules. However, it is considered best practice to have a local way to switch your cooker off, especially in a new kitchen.

 

Can you replace a cooker switch yourself?

You can replace a cooker switch yourself, but it’s not generally recommended. Cooker switches are hardwired into your home’s electrical system and normally run on their own dedicated breaker or fuse, so this isn’t the same as swapping out a light switch. If the wiring isn’t disconnected and reconnected correctly, you could risk damage to the appliance or the circuit. For safety and peace of mind, it’s best to hire a qualified electrician to handle the replacement

 

Where should you install a cooker switch?

A cooker switch should be easy to reach without leaning over a hot hob. It’s best installed above your worktop and at least 30cm to the side of the hob or cooking surface, not directly above or behind it. This keeps the switch safe from heat and steam, while making sure you can switch the cooker off quickly if you ever need to. If space is tight, the switch can be placed inside a cupboard, as long as it’s still clearly visible and simple to access.
