Hobs / the buying desk
Measure the hole, not just the hob.
Keep the worktop cut-out and outer dimensions as separate measurements. Then check the supply and installation requirements.

Hobs buying notes
Read the hobs guide →Space and clearance checker
Check one dimension at a time using measurements you have verified. Enter the clearance from the exact product instructions; this calculator does not decide a safe installation allowance.
Hob type
Use the manufacturer’s installation drawing for the cut-out and clearances. A familiar width category does not establish whether a replacement will fit an existing opening.
Cut-out dimensions
Choose gas, induction or radiant electric before comparing zones and controls. Ask a suitably qualified installer about the actual supply and fitting requirements.
Supply requirements
Keep the supply requirements with the model reference when asking an installer for a quote.
