Insulating a house

[Mumof3darlings]

Anyone got any ideas how to retro insulate a house which has been fully renovated but clearly badly so it looses so much heat!

Don't know where to look for advice as nobody seems interested since we don't qualify for a grant for insulation.

You need to find where the heat loss is first. Rent a heat gun, or get a heat loss survey. Then you can prioritise.

Thank you. Any idea where you get a heat loss survey from where they are independent?

I presume you already have decent double glazing and plenty of loft insulation? Do you have solid or cavity walls? If cavity, are they insulated already?
If solid, your only options are internal or external wall insulation.

You can measure the amount of heat loss in your home with a fairly simple test available from Build Test Solutions or Purrmetrix. Once you know that you can run an IR camera over the house to try and figure out where the heat loss is worst.

You can also get a retrofit surveyor to come and do a full survey that will estimate the heat loss from what they can see. Basically they measure everything - windows, doors, walls etc, check (if they can) what it's made of, and then put it all into a big software model that estimates the heat loss from each element then adds it all up. It's not as accurate (actually it can be waaaay off) but really you're paying for the advice on where to start. Try googling 'PAS 2035 retrofit assessor' for someone local to you, or services like Furbnow are pretty good.

I got a thermal imaging camera and used that to identify where the cold spots were. I am still working on addressing them.

It's an expensive solution, for me the camera has other applications so is worth the money, but they are pretty pricey but work really well.

It is easy to spot stuff like cold spots, gaps in loft insulation etc. Also useful for checking electrics and working out where the radiator pipes go.
