We dry ours on maidens/airers inside without the heating on, if the sun is out it goes on the line. There's only 2 of us so the weekly wash fits on two of them, it takes about a day to dry and job done. Sometimes we just hang our washed clothes on coat hangars on the door frames and they're dry in a day. Bedding takes a bit longer but we wash a set to go into the airing cupboard as a spare and then put the spare one on so it isn't a problem.
I've heard of so many people who do small daily washes and then they just bung stuff in the tumble dryer, it's no wonder that their bills are so high. We're very careful and are down to 5-7 kWh daily usage on the electric, estimated annual usage is 2200 kWh just on the electric and we couldn't get that any lower really as we work from home.
The problem nowadays is people want convenience and then that becomes normalised hence why people have such high bills but some of it is due to choices. Small washes are stupid as is using a tumble dryer where it can be avoided, we've managed 3 years in this house without one so they can't be that important.
