My house has plenty. I’m very sensitive to lack of fresh air, so I would know. The kitchen fitters did a terrible job and left lots of holes in the walls behind the cabinets and the floor is extremely draughty. There are huge exposed air bricks to keep the timber dry which also causes draughts everywhere downstairs even with good carpeting. And it’s open plan from the kitchen to upstairs so those draughts make their way upstairs. I also live on a hill and get plenty of prevailing wind. I spend a huge amount on energy trying to keep warm - it’s hard to know which bits to tackle to keep warm but not to cause structural and other problems… MVHR makes total sense and sounds superior. I’m sure the builders have successfully lobbied against such a sensible suggestion for decades and that’s why we have (I imagine) such stupid and basic solutions in our building regulations. I feel like UK houses lack infrastructure that the likes of the US and Europe have. Even kitchen ventilation is such an afterthought
