Don't take money out of the bank as that will incur more charges
Do work out all your outgoings, council tax electric, gas, water, house insurance, TV licence, mobile phone, sky, internet, car etc and then see what you have left over
Then cut back on shopping and what you have left over goes into paying off overdraft
See if you can reduce any of your utility bills or change companies to reduce outgoings
I got rid of my land line phone and get broad band on cabel, this saved me £20 per month so £240 over the year. I also dumped the TV as we didn't really watch it and that saved the licence money ,- we use catch up if there is anything we want to see. So that was £145 saved. I changed my house hold insurance and saved ,£10 per month, so another £120 per year. My mobile is with giff gaff and virgin and I pay £20 per month for unlimited text and ,1200 minutes with internet.
You have to work at your finances but I now save £500 each year on my utilities by doing things a bit different.
I phoned the gas and electric two weeks ago and they owed me £250 because they were taking to much money on direct debit and the DD has also been reduced and I got the money back.
