Energy saving trust significantly downgrades energy saving estimates

Energy saving trust has significantly downgraded the estimated energy savings achievable from activities like insulating your loft or having wall insulation installed. This is because the figures it had been using were way over estimated. They are now nearer to the Green Deal figures, but both of these are still significantly higher than the actual data measured by the government's energy department. (BBC Radio 4, You and Yours)

The only difference I acutally noticed after insulating the loft was that it stayed too hot in the bedrooms at night in the summer.

Thats assuming 100mm layed seamlessly across the whole loft. Usually the 100mm is layed between the joists resulting in quite a few air gaps, in which case laying another layer at right angles over joists makes a lot of difference. Simon.

You could probably make better savings by just adding TRVs, timeclocks and a room stat etc to old boiler setups and keep the old boiler.
