If someone is trying to make claims of legal requirements one would assume that they actually know what they are.

As has been quite correctly pointed out there is no legal requirement for mechanical ventilation in a house with opening windows. It’s a nonsensical statement.

>Edit: I've got a couple of teenagers and they can spend a half hour in the shower with no fan running and turn the bathroom into a wet steamy mess! So the extra fan helps to clear this quicker when required. <

Similar situation so got a shower dome fitted ... problem disappeared immediately 😁

i never said a house with opening windows required mechanical ventilation with a certain flow rate. i said "35l/s (the legal minimum)", thats all. you made up the rest yourself, not me.
