My daughter has a newly-built house, and recently a bulb blew in her cooker hood. Her husband replaced the bulb but neither the lights nor the fan are working. They think a fuse must have blown, which seems right, no MCB in the consumer unit has tripped, so it must be an individual fuse.

I am used to appliances being connected via a switched fused connection unit but this is different. There is a 5 gang switch box above the work surface labelled for the various appliances, but there are no fuses there, and I cannot see them elsewhere either, having looked at the back of the base units, on top of the wall units and everywhere else I can think of without success.

I can only suppose that the appliances have a fused flex outlet behind them, but that would make the fuses highly inaccessible, when you consider moving out the fridge-freezer, the dishwasher and so on. The cooker hood is sealed against the wall with silicone and I am reluctant to pull it off and cause damage to the decorations without knowing for certain that I will find the fuse behind it. Is it possible the fuse could be anywhere else?

The instruction manual for the hood assumes it is connected to a separate switched fused connection unit, so there is no fuse built in. The builder is not being helpful,

Sadly there is no specific answer other than to continue to look. The fused connection unit (If there is one) could be anywhere.
Have you looked at the manual for this cooker hood, it may have an internal fuse.

Quite often with new installations, looks are rated higher than practicality, push button toilet cisterns are quite common, the mechanism fails and the cistern is boxed in and tiled over, looks nice, but the tiles have to be removed.

I can only wish you luck.

No, no internal fuse in the unit. I can only think there is a fused connection unit behind the hood and hidden by the extractor trunking, so that trunking is going to have to come off I fear. I just wondered if there could be some new system with a bank of fuses out of sight somewhere. I know what you mean about looks taking priority over practicality!
