Margaret, didn't you post a link to some 'special' paint additive that helps with damp and reflects heat?
We recently had a leaflet through about solar water heating, they were quoting ~£1500 fitted. I know of one house that has it, anyone else considered it? We don't have a water cylinder so its no use for me. I have considered a wind turbine but I don't reckon teh neighbours woudlo be that chuffed
other energy saving tips,
if you have single glazed windows yu can get cling film stuff that you fit to add a 'double glazing' effect, I heard they aren't as good as real DG but better than single. Otherwise, as someone else said, draw your curtains when its going cool and have as heavy a curtain as you can.
Turn your thermostat down a couple of degrees, you won't notice
set your central heating to come on 10 mins later and off 10 mins earlier
measure teh water you put in teh kettle so you don't boil too much
put lids on pans when cooking food, you can turn the heat down for teh same effect
make sure your house is insulated properly(particularly loft), lag pipes, etc
