Everyone says; turn down the heating, but many of us can't, due to heath issues.
So here are my tips and I hope you will all contribute other good ones.
Check that all appliances such as fridge, freezer, washing machine and dryer are fairly new and use as little energy as possible.
If they are older models, buying new, if you can spare the cash, should lower your consumption of electricity.
Use the dryer as little as possible. I only use mine during the winter and only for bed-linen and denim jeans.
Make stews, and things like stovies where everything is cooked in one pot, once a week or so.
Plan meals, so when baking bread you can have a casserole for dinner in the oven at the same time.
I have filled a small copper kettle and placed it on a radiator - the water gets quite warm enough for washing your hands or rinsing something.
If you have a wood-burner, keep a kettle on the top of it too.
Turn the thermostate on the shower down a notch, unless your back is very sore.
Can you wear some clothes a day longer to reduce the amount of washing needed?
If the bills get much higher, dig out a war-time cookery book and revert to cooking potatoes, other vegetables, porridge and rice pudding by bringing them to the boil on the stove and putting the into the hay box to finish cooking.
You can make a good modern hay box using old blankets or quilts instead of hay.
If buying a new cooker, opt for an induction hob. It should use less electricity than anything else.
If you haven't already done so, change all light bulbs to LED.
Hope you have other good ideas to share.
