Enquiry preparation
Cooker: agree the proposed work before choosing components
For a cooker enquiry: Ask what labour, parts and further attendance would involve. Website guidance cannot establish that a particular part is needed, available or included in a final charge.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Keep the hob, grill and oven observations distinct. Give the fuel arrangement and the actual cavity or burner involved. Suitable gas-related work requires specific agreement; this site does not offer gas conversions or AGA repairs.
The purpose of this detail
The cooker reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
What still needs agreement
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
