I was reducing mine anyway due to the £5 a day gas reading on the smart meter, I'm trying to reduce again due to the situation in Ukraine, we do need reduce our gas usage as Putin is using it as leverage. Europeans have been asked to reduce their heating by 1c to help this. It feels a bit like Dig for Victory but with heating.
This is what has helped me:
Heating on short time in the morning and early evening, it is set to 18, I've cut the usage in half.
Hot water bottles in fluffy covers are great for keeping warm
I've found that pure wool blankets and jumpers are best, they work better than synthetic, although fleece is good.
I'm thinking of getting a slow cooker before the autumn.
No more long showers
Thermal curtains and blinds
No tumble drying
Extra loft insulation
Fix gaps in doors, windows etc where heat is escaping, this has made a huge difference. Be careful not to cause damp issues.
Dehumidifiers are good for drying out your house and preventing damp, dry air is easier to heat and it feels more comfortable at a lower temperature. I've found that running a low energy dehumidifier when drying washing is cheaper than heating the house more, I'm running mine for half an hour twice a day. They can be expensive to buy, I know it isn't an option for everyone. I worry about how people are going to cope with the price rises, everything is so expensive already. I'm really worried about people who need higher temperatures due to being ill or elderly, it's extortionate to keep a house warm day and night. I can pay the bills and cope with the cold, but not everyone can.
I bought a window vacuum a couple of weeks ago, they are great for reducing any condensation on windows or in the bathroom, helps make the whole house drier and more comfortable.
Solar panels with a battery are on my wish list, along with wall insulation.
The government should start a scheme to pay for insulating homes asap, this would help with climate change targets too and help wean us off gas, helping with the geopolitical situation. Our housing stock in the UK is not well insulated, we need to change this and now we have three reasons to do it: price rises, Ukraine and climate change.
