Not having insulation in your walls is strange to me.
Terraced houses init. Next door provides the insulation. Unless you are unlucky as in Aggi's case where you are the end of the terrace, in which case you have a huge combined heat sink & cold bridge.
The real fuckers are pre 1950s detached houses and semis that either had single skinned brick walls or (if you were lucky) cavity walls with just an air-gap.
If I was in an EOT or the Edwardian semi we nearly bought, I'd get something on the exposed wall if I could. Suspect the boundaries might be an issue with external insulation which is a right fucker as internal is both shitter and a more of a ball ache to do.
Mrs Howard's parents gaff in Canada always amazed me with its ability to retain warmth despite the outside temperature being mega-cold.
