Hrft but went from ok to not ok to ok and back to not, both times due to DHs illness, first one died, second one us hanging in there for now. Neither had good income insurance sadly..
Reduce waste, everything you throw unused is a loss to your budget. So take a long hard look at what you throw and try to cut it by at least half. For me that means freezing cheap bread so I've got something for toast in short weeks. Only buying enough salad for one meal, or eating it 2 days consecutively to use it up.
I read somewhere to shop 3 weeks and live on leftovers for last week in a month, I like the idea but couldn't quite make it work yet.
Know how much you spend, on anything.
Cut subscriptions and contracts eg phone and internet to a minimum.
Look at keeping your transport bill down by walking more or incorporating travel to shops in the commute.
If you've got saleable stuff, ebay or vinted can be your friend.
Free stuff can be great but don't spend alot by travelling miles to get something worth £5.
Do any offers or coupons but only if you would buy the item anyway.
Use up unwanted toiletries as hand-wash, air freshener, toilet cleaner, whatever they work for.
Grow things if you can, but don't spend a fortune on seeds at first, find a local plant group to get cheap starter plants and advice.
Wear outer clothes an extra time, to save on wash powder and costs, I wear my top inside out at home to avoid stains showing then turn it round when I get to work/drop offs. But I'm messy, so you might find better ways to keep cleaner longer.
If you can work extra hours now and again do it,, but not all the time as you'll get sick/tired.
Skint Dad is a great resource.
