- Save £2,000 by starting with 20p and increasing your deposit by 40p each day until Christmas Eve.
- Take 16 minutes on Money Reset Day to review subscriptions, bills, borrowing and savings and identify ways to cut costs or boost your income.
September 16th is 100 days until Christmas; that’s why we’re renaming it - Money Reset Day. All you need to do is take 16 minutes on 16 September to reset your money.
Below we’ll explain how to do it and how to take part in Money Reset Day or our 100 days to Christmas savings challenge.
Save up to £2,000 before Christmas
Saving up small amounts between now and Christmas Eve, and you could have £2,000 - and all you need is 20p to start.
You can start the challenge whenever you want, but September 16 gives you 100 days until the 25th of December.
Try increasing the amount you save each day. How much you increase your payment depends on your final target.
We’ve created downloadable and printable trackers so that you can keep track of how much you want to save based on having £500, £1,000 or £2,000.

If £2,000 feels unrealistic, the challenge can be scaled down. Starting with 10p and adding 20p each day produces £1,000, while beginning with 5p and increasing the payment by 10p a day builds a £500 fund.

Pick an amount that fits comfortably alongside your bills and other financial commitments, as the whole point is creating a savings plan that is manageable.
You could make each transfer manually, use scheduled payments where your banking app allows it, or keep a checklist and transfer the week’s total into a separate savings account.
Keeping the money away from your everyday spending account should make it less tempting to dip into.
Even better if you can use a savings account is a high interest. It’s worth checking out which one would work for you by comparing savings accounts.
Take the Money Reset Day challenge
Savings challenges are great for getting you into the habit of saving money - but if you don’t have any spare cash or your budgets are tight, then you need to unlock some.

Eligibility, fees and offer periods vary.

Move your savings to a better rate: earn £41 more by Christmas
Check the interest rate on your savings rather than assuming it is competitive. Moving £5,000 from an account paying 1% to one paying 4% could earn approximately £41 more over the 100 days to Christmas, or £150 more over a full year, before tax where applicable.
-
Check your energy tariff
The energy price cap rose by 13% in July 2026, taking the illustrative annual bill for a typical dual-fuel household paying by direct debit to £1,663 under Ofgem's updated usage measure. Check whether a fixed tariff could cost less, taking any exit fees into account. Switching appliances off at the plug could save around £45 a year.⁷
-
Check your broadband contract: potentially save £84 to £108 a year⁸
Find out whether you are out of contract and compare new deals or ask your existing provider to reduce your bill. Ofcom says customers who are in contract typically pay £7 to £9 less each month than those who are out of contract, equivalent to £84 to £108 a year.

Check your mobile contract: potentially save £262⁹ a year
If you have finished paying for your handset, consider keeping it and moving to a SIM-only deal. Switching from an ending 24-month handset contract to an equivalent SIM-only plan could save £262 a year, or approximately £22 a month.
-
Downshift your supermarket shop: potentially save £52010 a year
Try replacing branded groceries with cheaper own-brand alternatives, starting with products where you are unlikely to notice a significant difference. Cutting £10 from a £30 weekly shop would save £520 over a year. The amount you save depends on what you buy and how much you normally spend.
-
Check whether you are missing out on benefits: potentially unlock £5,39611 a year
Use a free benefits calculator to check whether you qualify for Universal Credit, council tax support, childcare help, social tariffs or other assistance.

You can also ask Citizens Advice for help understanding what you may be able to claim.
-
Use a cashback website: potentially earn £30012 a year
Before buying something online, check whether a cashback website offers money back from the retailer. TopCashback says members could earn an average of more than £300 a year when shopping across its specified categories and referring a friend. Cashback is never guaranteed, so buy only what you intended to purchase and don't choose a more expensive retailer purely for the cashback.

Sell unwanted clothes, toys, electronics and homeware through platforms such as Vinted or eBay. eBay research found that 76% of people who sell online make less than £150 a year, although nearly a quarter of UK households believe they have unwanted belongings worth more than £500.
