    I live in a traditional Cotswold cottage, about 400 years old and yes. It's a cave - stuffy in summer and freezing in winter.

    Sometimes I wonder if it would be more comfortable to just sleep in the garden. Looks pretty though.

    Physics 101 was wasted on you. Rubble / stone no matter how thick is a terrible insulator while being an excellent conductor.

    But make sure you put the insulation on the outside and not the inside; otherwise you lose the effect of mass that will keep you cool in the summer. More on that later.
    Then the article ended...

    It can be 90 degrees outside & coming inside is like stepping into a nice cool cave. No need for air con here.

    Negative influencers, according to the guy who came out were no loft insulation and no cavity wall insulation.

    Can only hope prospective purchasers don't pay any attention to them because they're clearly totally inaccurate unless you live in a modern Baratt style home.
    Is it listed? If it is, you're stuck with what you have, and nobody looks at the EPC ratings anyway.

    Yes, hope you're right.

    Yes, those ones that take 30 seconds to light up after you've switched them on. Just what you need on a dark Monday morning when you're in a rush and can't find your keys . I whipped those straight out when I moved in.

    They are a bit crap. I look at them and go 'meh'.
