I am beginning to think the two are mutually exclusive. It's so expensive to refit with modern standards, and the solid brick walls rule out cavity insulation.
I read things saying stop up all holes etc, air bricks etc to prevent spiders, mice, drafts - we have parquet flooring and all the pipes and wiring come up higgly piggly, it's impossible.
Not a stealth boast, now the weather is changing, I have got a temperature, and miserable already. I'm looking at much less beautiful homes, constructed since 2000, but dh will never agree to leave our victorian villa :(
