Measuring up

Gas hobs typically have a depth of 50cm (from the front of the unit to the splash back) and a height of 5cm (the part of your hob that sits into the worktop), with width sizes ranging from 60-90cm. If you’re swapping like for like, for example a 4 burner hob for a new 4 burner, all you need to do is measure the width of your current appliance from edge to edge. If these measurements are a few millimetres shorter or longer than the hob you have your eye on, don’t worry, it will still fit.

The Hot Zone

When measuring for a brand new gas hob, you’ll need to think about the amount of free space above the hob. This is called the Hot Zone and it needs to be clear of any flammable items like wood, wallpaper or wiring. We recommend that you leave at least 65cm between the bottom of the cooker hood to the top of your gas hob. Keep in mind that your hob needs to be the same width or smaller than the cooker hood above. This just ensures all those cooking aromas are caught by the extractor fan.

Space below the hob

If you’re putting your hob above an oven, we recommend that you leave a gap of 25mm between them for air to circulate. If you’re going to put the hob over a drawer unit, a partition will need to be fitted to protect what’s in the drawer. If this is the case, then the gap only needs to be between 15-25mm to make sure there’s enough room for the air to flow. However, it’s important to note that some manufacturers might say something different so keep an eye out for what they say in their installation instructions.
