Enquiry preparation
Cooker: make a short sequence of events
For a cooker enquiry: Describe selection, operation and outcome in that order. Add anything that still responds normally, keeping your observation separate from a suggested failed component.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Separate hob, grill and oven behaviour, and give the fuel arrangement. Gas-related work must be agreed individually; gas conversions and AGA repairs are outside our service.
How this supports the discussion
The cooker 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.
