We've just booked expensive new double glazed windows that we've needed for a while. It's wiping out a large chunk of my savings but the forthcoming recession and energy payment hike made me get on with it as it will make a huge difference to the insulation of our house.
Having said that, I have had butterflies since paying the first instalment as it is such a huge amount of money.
I otherwise am cutting right down on expenditure: less Ocado, much less, and more Lidl. Cheaper toiletries, no new clothes unless strictly necessary, and running the dishwasher on its eco setting and doing loads of washing less often. Taking a thermos of coffee to work instead of buying flat whites, taking tea bags in for the afternoon, and cutting right back on treats eg takeaways.
I dont' usually budget very much as I earn enough usually to save a bit each month, even after my pension etc payments, but now I'm noticing the cost of living very sharply so am taking proper steps to curb unnecessary expenditure. It's quite satisfying, really, but I have no doubt the novelty will wear off.
