Are you planning to replace your old built-in cooker hob with a new one? Before you start the replacement process, it’s important to choose the right type of cooker hob that suits your needs. Follow these simple steps to make sure your new hob fits perfectly and meets your cooking requirements.
Step 1: Choose the Type of Cooker Hob
The first step in replacing your old cooker hob is deciding on the type of hob you want. Ask yourself the following questions:
- Material: Do you prefer a stainless steel gas hob, a tempered glass gas hob, or a built-in induction hob?
- Burners: How many burners do you need? Would a 2-burner hob be sufficient, or do you need a 3-burner hob for more cooking space?
Once you’ve decided on the material and number of burners, the next step is to ensure that your new hob will fit into the existing space in your kitchen.
Step 2: Measure the Existing Cut-Out Hole
Now that you know the type of hob you need, it’s crucial to measure the existing cut-out hole on your countertop. This will help you determine if your new hob will fit. Here’s how you can do it:
- Remove the Old Hob: If you haven’t already, carefully remove the old cooker hob to expose the cut-out hole.
- Measure the Cut-Out Size: Use a measuring tape to measure the length, depth, and radius of the existing cut-out hole. If you’re unsure, it’s best to measure from underneath the old hob, or even remove the old hob completely to get a more accurate measurement.

Step 3: Check the New Hob’s Dimensions
Once you’ve measured the existing cut-out, you can now compare those measurements with the dimensions of your new built-in cooker hob. Most manufacturers will provide specific cut-out requirements for their hobs, which will look something like this:

Does the New Hob Fit?
- If the existing cut-out dimensions match the required measurements for your new cooker hob, you’re good to go. You can proceed with purchasing your new hob.
- If the existing cut-out hole is larger than required, you may need to consider a different hob model with a smaller size.
- If the cut-out hole is slightly smaller, your installer can alter the hole to fit the new hob, but be aware that this may incur extra costs for the cutting and resizing work.
Step 4: Final Considerations
Once you’ve confirmed that the new hob will fit, you’re ready to purchase and install your new cooker hob. Don’t forget to choose a reliable supplier to ensure you’re getting the best deal on quality products.
