Enquiry preparation
Cooker: keep a short fault diary
For a cooker enquiry: Record a few ordinary occurrences with the programme and stage. Do not deliberately recreate smoke, tripping, leakage near electricity or uncontrolled movement for a video.
Model and requested work checked before an appointment is agreed.

Name the fuel and the affected hob, grill or oven section. Suitable gas-related enquiries need individual confirmation before any attendance is arranged.
Why the detail helps
The cooker reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Before an appointment is agreed
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
