Of the appliances you mention, only the tumble drier is expensive in electricity. It probably uses about 3kW, so that's around 45p an hour.
The washing machine uses a similar amount, but only for about ten minutes while it heats the water, so that's around 7.5pence per wash.
I am assuming you pay around 15p per kWh. Check your bill to see.
Do you have an electric shower? It will cost around £1.35 per hour.
How do you heat your hot water?
How do you heat your house?
Do you have an electric cooker?
Finally, look past the amount of your monthly direct debit, which may not match your usage because there may be estimates and old balanced included in the calculation.
Look at the meter readings.
Do you know the reading from a year ago or a month ago? Compare it to today's reading, What's the kWh used?
if not, find the oldest electricity bill you can and compare the reading to today. Take weekly readings for a while.
Actual usage numbers are important to seeing what's happening.
