Go through every single direct debit and standing order to check you need them. I found I overpaid for my child’s clarinet rental.
Check for discount codes. There are so many.
Downgrade your mobile tariff. Check your insurance quotes. I saved 20 quid a month on the latter and got a 20 quid Lidl voucher for buying insurance from Comparethemarket. I cut my mobile tariff from 25 to 8 quid.
Check for supermarket own brand stuff, e.g., I buy Tesco Stockwell brand weetabix - 24 biscuits for 78p. Branded stuff is 3 quid.
Invest in Primark oodies - I live in mine at home. So cosy! I haven’t switched on my heating yet and don’t intend to until Dec at the earliest.
Work from the office (if you have one) to save on energy bills. No energy used in my house from 8am-5pm.
Always check on eBay or other second hand site for expensive brands. But first ask - DO I NEED IT? I constantly ask myself this and have cut down massively on clothes shopping. I have enough to last me years, in fact.
Switch off everything at the sockets when not in use. I’m sure I’ve brought down my electricity bill from this. I only use low energy lamps and don’t switch on the ceiling spots.
Check which companies offer perks eg O2 does. I used to be able to get a free Cafe Nero drink every week. Now it’s Greggs.
I save 20-25% a week using my Tesco club card.
Toiletries and cleaning stuff is cheaper at Supersavers (owned by Superdrug) than Boots or Superdrug. I’ve cut down on toiletries - owning using what I absolutely need. Bog roll is expensive!! Shop around.
