Hi,
I made a spreadsheet of all my income and outcome so I knew how much I was spending on everything and how much I had spare.
I then changed gas and electric and broadband to cheaper deals by using comparative websites.
I cancelled things like NowTv and Spotify and just used the free version.
It’s little things that you can change that mean you will still live comfortably but can put the money you save into savings for your kids.
There are good interest rates on savings accounts and Isa’s as well. So even of you only put a small bit away each month it will grow and grow over time.
Hope that is some help 🙂
