When I first moved to my three-bedroom home – a semi-detached 1980s bungalow near Swindon – there was a fair amount of work to do.

The property had a loft conversion added to it around early 2000 and it had been built badly and needed rectifying. The house did have cavity wall insulation but not much else when it came to preventing heat leaking to the outside world.
