Dead easy. I used a 75mm thick bit of celotex, glued into place with expanding foam, then rendered over it.This easy enough to do? I'll look for a video online

What heating patterns?GCH, piped in old microbore sp not ideal, I have it balanced so most flow goes to living room. Coldest room in the house is the kitchen (cold to the point it feels like outside) and to be fair the radiator in there is in a terrible position and blocked by tumble dryer, so there are some less than ideal factors but it's the scale of *how* cold it gets and the speed at which the temperature drops which is so unusual
I'd stuff it with mineral wool loft insulation, and screw the vent back on.
It might be useful one day.
Also, use the joss sticks to search for holes in the floor where pipes (and sometimes cables) come up. There may be a plumbing duct in a fairly modern house.
If you do not have access to brown loft wool treated with Ecose, which prevents it shedding dust and fibres, stuff it in a plastic bag.
For fine gaps, scrub them clean to remove dust and dirt (leave them damp) and use expanding foam (preferably the pink fire grade)
What heating patterns?
If you are not warming the house up it wont stay warm.
And are the radiators sized correctly to actually heat the rooms up?
Even an uninsulated house should be able to be kept warm with correctly sized radiators.
And this old council house, is it a system built one with concrete internal walls?

I think the existing vent is cemented in so assume I'll have to chisel it out, suppose I'm as well just sealing ot up after that. Never did that sort of work before, I've assumed to leave about 10mm to the insulation then fill with cement?

that looks to me like an old ventilator for a food cupboard, not a drier. Is it quite an old house?
That sounds good, although I'd leave more than 10mm, but I'm no expert.Cheers mate, I've never done this work before so I've assumed it's as follows:
Chisel out old vent
Push in insulation (I already have the polystyrene type boards so will probably use that)
Leave about 10mm gap to front of wall and fill with cement
That all sound about right with what you did?
You think it's helped thermally?
Oh right, I just assumed it was for an old tumble dryer, I suppose it doesn't make a difference either way in that I should still block it off to try and help with draught/cold issues in kitchen?
House is from about 1975
Your photo of the vent, looks like concrete system built, but I may well be wrong. However it looks as if it was put in after it was built so you might be correct, a drier vent.
If you are correct, and there is a cavity wall there, you will need to block both inner and outer leaves of the wall. No point in just blocking the outer as cavity will continue to allow drafts in.
You mentioned blocking both the inner and outer parts of the wall, can I do this with a single bit of insulation that bridges the 2 or should I maintain a cavity in between 2 separate bits of insulation?
