unless taken as a whole you do tend to create other issues or spunk your money away for no real gain (environmentally or otherwise), unless you're either very lucky (not like me) or well informed.
I think the biggest heat loss in our house is down through to the double garage which is beneath the main bedroom, with very little / no insulation in the floor. I'd be reluctant to pull up the entire floor and insulate beneath (floor to ceiling IKEA wardrobes etc) but would covering the garage roof with insulation boarding be a good fix, or would it make little difference?

Thanks Chris, just ordered a pair of those Sherpa Slipper Boots for 20squid, luvvlyjubbly

The room by room approach was what I was going to do, are you saying you don’t get any benefit or that it would be better to do the whole house. Some of the things recommended are never going to be possible in my house (moving every window!?) but surely adding internal insulation to the external walls can help?

Modern gas combi boilers are ~ 96% efficient
modern combi boilers are about as efficient a way to use gas as possible
I could, but that would mean removing and replacing about 20 sq m of plasterboard which would be a grim and time consuming job, and result in a lot of landfill.
IF, and its a big if, we find a cheap, easy way to produce Hydrogen, and (and its a big and) the gas network can be upgraded to take hydrogen*, and, boilers can be manufactured to burn it safely in the home, then we might have a truly efficient, ultra low, non nuclear energy source. We can but dream. (* hydrogen, being such a tiny atom, compared to the long chain molecules of methane/ethane/propane, will leak through gaps in the gas distribution network that we don't even know about yet. ).
Whilst sticking a massive tea cost over the building seems superficiality attractive I imagine the walls will always be significantly colder than the desired internal temp so will constantly be drawing heat out of the room whereas with internal insulation would trap it in the room.
I've heard some good things about this stuff for internal insulation rendering, as it's porous but stuck on to the walls: https://norfolkrendering.co.uk/diathonite-evolution/179/ (note, I'm not in the trade and can't even remember where I heard about it, might have been a podcast?)
