Enquiry preparation
Hob: retain the occasions when it happens
For a hob enquiry: Keep a brief record of settings and results during ordinary use. Never repeat smoke, burning, leakage near electrics or uncontrolled movement for a recording.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Identify electric, induction or gas format and which zone changed. For induction, include any normal-use pan-recognition message without deliberately repeating unsafe tests.
How this supports the discussion
The hob reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Confirm the proposed attendance
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
