Winter's here so I'm thinking about cavity wall insulation.

Is it worth it - does it make a difference ?


I had my 1980s house done years ago - in November, from memory.
Before and after the big day I recorded the temperature in a bedroom where
the radiators were turned off. I had the bedroom door closed, so it's
heating was by leakage from the rest of the house which was thermostatically
controlled. The bedroom goes from front to rear of the house, and has
external walls on 3 sides with single glazed windows back and front. The
weather before and after installation was broadly similar, and I recall that
my unheated bedroom was noticeably warmer after insulation was installed.

It'll only make it warmer if the heating system can't keep up with the
heating requirements, but it will reduce the energy required to keep it
