I am open to having the house insulated.
In fact when we bought it 15 years ago there was a Government grant to get it done for free.
We applied and the company turned up to do inject cavity insulation. They looked at our lovely house where the top half is of a rendered style and said you do realise that we are going to shotgun your whole house with holes.
Unless we re-render the house we can’t insulate it.
Yes, you are right and double glazing made a huge difference. The loft was converted many years before we bought the house and although the flat roof part is insulated, the tiled sides are not.
When we did the kitchen extension it was properly insulated and that is now the warmest room in the house.
Another option is to internally insulate the external walls, but that is best done if you buy a proper do-er-up-er.
We have taken our insulation as far as economically practical. Which unfortunately is not enough to make the house comfortable in the depths of winter.
However, I have learned what is on my insulation wish list when I retire an move out of the London borders in the next 5 years or so.
I was working at house the other day which has just had the whole external walls insulated then rendered. I had to screw something to the external wall and they gave me these big plastic plugs that have to be screwed in first before you can fix anything. Like great big plasterboard fixings.
I always thought that the external wall insulation panels they put on were like a solid insulation. I was shocked when they said it was like polystyrene. So give them a good punch and you dent the wall.
