Enquiry preparation
Cooker hood: retain the differences you have already noticed
For a cooker hood enquiry: Settings and outcomes from ordinary use can help describe variation. Keep the observations as a short note. Do not deliberately repeat burning, smoke, tripping, leakage near electrics or uncontrolled movement.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Explain lighting, speed selection and air movement separately. If known, state whether air recirculates through filters or travels through an outside duct. Leave the fitted hood in place; there is no need to climb up or dismantle it.
The purpose of this detail
The cooker hood 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.
