OP do you have a smart meter? If not, definitely get one installed - most energy companies will do this for free and it will only take a few hours to get set up.
The huge advantage is that you can constanly keep an eye on your meter to see how much you are using in real time - and how it compares to your overall budget (i.e. your DD/ monthly payments).
I am only using just over £1 daily at the moment. Given my DD is set at £125 pcm it means that I am using only a third of what I am paying right now, building up decent credit. I also don't have to faff with readings as they are sent to the company automatically, so I can also view my monthly bill in real time online.
The smart meter can also bet set up to warn you about high usage (when you go over a budget that you can specify), and it will tell you when during the day you are using particularly high amounts of energy.
As for washing - my washing is out on the line every month of the year, even in winter. It might take a day or two to dry rather than two hours like it does in mid-summer, but it is well worth it to avoid damp in the house. And if it doesn't get completely dry outside, there will still be a massive difference in how fast it dries once back inside the house. Fresh air has that effect. Additionally, sunlight can remove some small, but annoying stains.
