No-one mentioned cavity wall insulation. Have been thinking about this.. I've heard that it can go horribly wrong and encourage damp. Anyone know to look out for when considering this?
Oddly (or maybe this is normal for the period of house - Edwardian Semi) - I believe I only have a cavity on the ground floor. The first floor is solid double layer

Well when you have planning depts that refuse permission to build zero energy Passivhaus houses on previously developed brownfield sites but are happy to leave a 400yo wholly inefficient energy guzzler in place you know there are fundamental issues that need to be changed.
However are happy to have a same sized garage/gym/storage building of any construction on the same footprint, the same size, that can use as much energy as you want with no requirements for any level of energy efficiency at all. Total sense

Yup, don’t fill the cavity with water!

The biggest problem for you and cavity wall insulation causing damp is brick ties, they’d have been plain iron/steel back then so can rust through and the two walls will no longer be tied together, it was the 20s before galvanised ties came the norm. You might not have a cavity anyway.
Generally bricks get wet and dry in cycles of weather/use and internal insulation can hold condensation. The modern method now is an external insulation sheet, leaving the cavity alone.

I’ve also heard that using fermented hops, can generate heat in the cavity……heating the house.
Downside is a yeast infection so stock up on the Canestan.

I jumped on the Green Homes Grant scheme the other year and managed to get cavity wall and loft insulation done for a total of £900.
Same company came to do both, I even managed to get the entire loft boarded as part of the deal.
Have we noticed a difference? Difficult to say really.

Boiler sitting at about 55. Already was. Not much to save there.

My dad got into partnership with cavity wall insulation in the early 80's.
All I can can remember is a chemical mix that turned into foam that they injected willy nilly. The company didn't last long, and god only knows what mess they left years later with the houses they did insulate.
It was the thing to get into, like double glazing.

Well there was clearly a gap in the market and they filled it!

I followed a van with cavity wall insulation listed on its left hand rear door and cavity wall insulation removal on t’other door. ‘Nuff said?

Correct. I live about 5 miles from Shaftesbury.
