Having posted last week and discovered that yes, we were using a lot of electricty, and it wasn't just the prices going up, So DH and I have put some effort in.
The main thing was going round unplugging every single transformer that wasn't being used (not just rechargers for phones and laptops, we have a few (OK, 6) DAB radios, all of which have transformers that use a bit of electricity when the radio is off. The only other thing we did was make sure we put the computers to sleep when we walked away. We've been taking meter readings every morning and night, and our use is down 25% already.
There's still more work to do, as the house seems to use huge 'background' levels of electricity all the time, but we have been lent one of these which is not so lovely it's my new pet, but also making me completely obsessive about turning things off to see how low I can get it. More reports if we get below a 25% reduction.
ps. I know this is all probably blindingly obvious to some people, but it's been a surprise to me.
