@dLockers have you done anything about internal airbricks?

How do you mean?

There is one in the hall that is almost skirting board height which I'll fit a venting kit to. The others I have just vacuumed out.

Yeah I wondered if you kept them, given the need to insulate. It's something I need to consider in mine.

I'm not 100% following --- you need air bricks to ventilate the under floor.

I meant the ones (if any) within the rooms themselves. I get a real draft through some of mine, so how do you square the need to ventilate with the need to insulate?

Ah I think I understand. I don't have any vents in the room itself. All the airbricks just go to the underfloor. The only one that is an issue is the hallway vent is a bit high, so I'll put a 45 degree angled piece of PIR and a vent extender to get it right under the floor.

I was then advised to basically seal the floor to the walls to stop any draughts.

Yes this or telescopic vents are what you need to do

I have air bricks high up the walls in all three upstairs bedrooms, and several airbricks behind the cupboards in the kitchen. Can feel the draft flowing from under the cupboards in the kitchen when it's cold.

The bedroom ones aren't too bad, but i was thinking of blocking up the kitchen ones when I redo it. But will I create mould behind the cupboards with no ventilation?

Ahhhhhh I know what you mean now. My moms house (~1960s-1970s?) has those air bricks too. There is a vent in my brothers room and one in the kitchen. I'm not sure tbh. We fitted an extractor fan in the kitchen one, and my brother just put a stainless cover on his like what you see on chimneys that are blocked up.

They used to have air bricks added to houses to allow air ingress when there was gas fires in bedrooms etc.
