Fairly easy to fit just measure and cut out holes for the hood itself and exhaust,
I was doing a new install. The unit comes with a 3 pin plug attached
I hard wired mine into a spur unit. It can be used on recirculate or external extract. I was expecting it to be noisy but it was quieter than my old one. Overall the only thing seen is the grill panel, the lighting is quite good and I am happy with my choice
