What tradesman should I ask to repair/replace a faulty extractor hood hose?u

[TheOneWithTheNicestSmile]

The hose won't stay attached to the vent coming out of the extractor any more so it's just blowing grease into the kitchen. Lovely.

The kitchen was fitted 15 years ago & the supplier doesn't exist any more. Would a general electrician be able to sort it? It's the kind with a pull-out "door" & a cornice across the top so all that will need to be dismantled.

All helpful suggestions gratefully received!
