Enquiry preparation
Cooker hood: agree permission and entry
For a cooker hood enquiry: Establish the appliance owner, the person authorising work and who will provide access. Have these arrangements ready alongside the address before requesting attendance.
Model and requested work checked before an appointment is agreed.

Say which fan speeds respond and whether the lights work. A recirculating hood and an externally ducted one have different airflow arrangements.
Why the detail helps
The cooker hood 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.
