Bathroom extractor - help

[displaycase]

Cowboy builder - too boring to go into multiple errors many of which are structural

Latest is the bathroom extractor fan which I have discovered i vents directly into the loft space. Building control initially have now said it is illegal and needs to be rectified.

The builder is suggesting I just vent with a flexible pipe to the side of the roof (near fascia boards) , bend it slightly and then have the vent face actually face down towards the ground.

I have established this is one day work for him and easy as it requires no ladders!

I have googled and

1. Flexible duct not advised for a long run and
2. Bends not advised and
3. I cannot find anyone who thinks venting towards the ground is a possibility (this would be like smoking a cigarette while bending over - surely smoke gets in your eyes)

The alternative would have been to vent to side via a discrete grille (I’m in a conservation area) but scaffolding has been removed.
Or vent through bathroom wall. The problem with this is he says he can’t put up scaffolding so will have to use a ladder which means plonking an ugly white plastic extractor in the rear of my Georgian house (no one else has this)

What can should I do do you think?

When you say "an ugly white plastic extractor " I think you mean the vent.

Have one to tone with the brickwork.

Mine are brown.

It is easy to drill a hole for the duct through a brick wall, using a core drill, it can be done from inside. It's dusty.

All plumbers and builders have one.

The duct should be routed so that apart from the short section rising through the ceiling, it slopes slightly towards the outside so that condensation will drip out, and not collect in the pipe.

Or, better, ask around for personal recommendations if a competent builder or plumber, and give your current one the boot.

A roofer can also fit a special vent in place of a tile. But roofs are to keep the rain out so don't allow anyone inexpert to do it.
