Enquiry preparation
Cooker hood: read the whole rating label
For a cooker hood enquiry: Use paperwork or a label that is safely visible in the normal fitted position. Copy product suffixes and service references as well as the large brand name.
Model and requested work checked before an appointment is agreed.

Apply this to your product
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.
