Money leaves a current account in two ways. There is the spending you decide on — the weekly shop, the train fare, the round you bought on Friday — and there is the spending that happens whether you think about it or not. Direct debits, standing orders, card details saved on a website years ago and never thought about since. Most of us can account for the first kind. Almost nobody can account for the second.

That is not a discipline problem, and treating it as one is why most advice on how to save money slides straight off. A subscription business does not need you to use the thing it sells. It needs you not to cancel. That is the whole model, and it is why the price is always quoted by the month.

One thing before any of it. If your income does not cover your essentials, nothing below will close that gap, and no amount of cancelling things will turn a shortfall into a surplus. It is a different problem with a different answer, and free, impartial help exists for it: MoneyHelper, which is run by the government’s Money and Pensions Service, keeps a directory of free debt advice services. It costs nothing and it is not a last resort.


Convert Every Monthly Price Into a Year

Here is the reframe that does more work than any other habit on this page. Seven pounds a month for a service you no longer open is nothing — a sandwich, a coffee, forget about it. Eighty-four pounds a year is a train fare home or most of a weekend away. It is the same money. The only thing that changed is the unit it was quoted in, and the unit was chosen by the person selling it to you.

So convert everything, before you decide anything.

A monthOver a year
£3£36
£5£60
£7£84
£10£120
£15£180
£25£300
£40£480
£83.34£1,000.08
Every yearly figure is the monthly one multiplied by twelve. Nothing here is an estimate.

The last row is the one worth sitting with. A thousand pounds a year is a little over eighty-three pounds a month — found every month, and kept found. That is a real target and it is not a small one. Whether it is available to you depends entirely on what your money is doing now, which nobody writing an article can know. What we can do is say where eighty-three pounds a month tends to be hiding. If you want the whole picture in one place first, the Money and Pensions Service runs a free budget planner that adds up the incomings and outgoings and shows you what is left.


Find the Payments You Forgot You Agreed To

Open your banking app and read twelve months of statements. Not one month — twelve, because the annual renewals are the ones that hide, and they are usually the expensive ones. Do it alongside whoever else lives in the house, because the doubling-up happens between people rather than within them.

Then check the two places a bank statement will not show you clearly: subscriptions bought inside the App Store or Google Play, which live in your phone’s account settings rather than in your bank’s app, and anything paid by card rather than by direct debit, which will not appear in the direct debit list you were about to trust.

You are looking for shapes rather than brand names: music and video streaming, games services, cloud storage and photo backup, a gym, a delivery membership, software you subscribed to for one job and kept, an app you trialled, insurance add-ons sold alongside something else, boxes of things that arrive every month.

Two rules for the cull. Keep the ones you use and value — the point is to stop paying for what you had forgotten, not to strip your life of everything pleasant. And judge each one on the yearly figure from the table above, not the monthly one, because the monthly one is designed to be waved through.

If a Payment Will Not Stop

Recurring card payments — the ones taken from a debit or credit card rather than by direct debit — can be stopped by your bank, and this is worth knowing precisely. The FCA says your card issuer “must stop the payments – even if you haven’t contacted the business”, and “can’t insist that you contact the business before stopping the payment”. The timing is the part people miss: the FCA says to ask by the end of the business day before the next payment is due.

One catch, and it is the one that bites. Stopping the payment is not the same as ending the contract. Tell the business too, in writing, or you can find you have stopped paying for something you are still signed up to.

The law on this changes in January 2027, and it changes in favour of the person trying to leave. Under the subscription rules in the Digital Markets, Competition and Consumers Act 2024, a business selling a subscription will have to set the terms out clearly before you sign, remind you before the contract renews, make leaving straightforward, and give you 14 days to cancel once a free trial converts or a long contract rolls over. What the present arrangement is worth is the government’s own estimate: £1.6 billion a year spent on subscriptions people do not want, at an average of £14 a month for each one. None of it is in force at the time of writing, which is why the cancelling is still a job somebody has to do by hand.


The Bills That Go Up Because You Did Nothing

Staying put has a price, and in broadband somebody has measured it. Ofcom’s pricing and consumer engagement research, published on 26 February 2026, reports that 28% of broadband customers are out of contract, and that on average, customers who are in contract spend between £7 and £9 a month less than out-of-contract customers. Over a year that is a gap of £84 to £108. Read it for what it is — a difference in what two groups of broadband customers spend, not a quote for your line — but the direction of it is not an accident. Put the end date of your broadband contract in your calendar and ring them before it passes.

The same research covers something a lot of eligible households never hear about: social tariffs for broadband, ranging from £12.50 to £24 a month for people receiving certain benefits. If anyone in your household claims benefits, ask your provider whether you qualify.

Energy is the one where the number moves under you. Ofgem’s price cap sets the maximum a supplier can charge for a unit of energy and the standing charge together; it does not cap your total bill, and it is reset every three months. That is why you will not find a cap figure quoted on this page — it would be out of date before you read it. Check the level on Ofgem’s own page on the day you need it.

One change most households do not have to do anything about: VAT on domestic electricity is removed in Great Britain from 1 October 2026, falling from 5% to zero, which the government expects to take around £45 off the yearly Ofgem price cap in October. It applies for the rest of the 2026/27 financial year, there is nothing to claim and nobody to ring, and what happens after that has not been decided. Northern Ireland sits outside the cut: EU VAT rates still apply there on goods including electricity, so the rate cannot be changed without the EU’s agreement, and the Northern Ireland Executive is to receive comparable funding to support households instead.

For the rest, there are comparison sites. Uswitch covers energy, broadband, mobile and insurance for the UK market and displays the Ofgem Confidence Code certification mark in its footer. Before you lean on any comparison site, find its statement of how it is paid and which suppliers it covers. It is a business with commercial arrangements, not a regulator, and the cheapest tariff in the market is not always the cheapest tariff in the table.


The Week Before You Buy It

We give anything out of the ordinary a week. Not as a test of character — as a way of finding out whether the wanting survives contact with a wet Wednesday. Often it doesn’t, and the money stays where it was. When it does survive, you buy the thing without the low hum of doubt that trails an impulse purchase around for a fortnight.

The week has a legal backstop that a lot of people never use. For most things bought online, by phone or by post, the government’s guidance to sellers is that a refund must be offered if the customer says within 14 days of receiving the item that they want to cancel, with another 14 days to send it back. It is not universal. Personalised or custom-made items, perishables, newspapers and magazines, unwrapped CDs, DVDs and software, and sealed items that cannot be returned for hygiene reasons sit outside it — for those, the right only bites if the item is faulty.


Cashback Is a Discount, Not an Income

Cashback sites sit between you and a retailer. You click through them to the shop, the shop pays them a commission for sending you, and they hand back a share of it. Two that operate in the UK are TopCashback and Quidco, each of which says it covers more than 5,000 retailers.

The catches are real and you should price them in. Cashback is only paid if the click is tracked back to you, so anything that interferes with the tracking can cost you the payment — read each site’s own guidance on what breaks it before you count on the money. Payment is not immediate, and each site sets its own timescales. And the entire apparatus is built to move you towards spending: on money you were always going to spend, cashback is a discount; on money you weren’t, it is a marketing budget doing its job.


Keep the Spending Money Somewhere Else

The most reliable budgeting trick we know is physical separation. Some people draw the month’s spending money out in cash and watch the pile go down, which works well if you are not the sort of person who loses cash. The same idea works with accounts: money for spending lives in one place, money that is not for spending lives in another, and the second one has no card attached to it.

Many current accounts now let you split a balance into named sub-accounts — the names vary by provider — or you can open a second account and set a standing order for the day after payday. The mechanism matters less than the separation. What you are buying is the half-second of friction between wanting something and being able to pay for it.

Two things to check before you move money anywhere. First, whether the provider is a bank. Deposits with a UK-authorised bank, building society or credit union are protected by the FSCS up to £120,000 per eligible person, per authorised firm — a limit that rose from £85,000 on 1 December 2025. Not every brand with an app is a bank in its own right, and money held with one that is not sits under different rules; firms that share a banking licence also share one limit between them. The FSCS publishes a tool that names the authorised firm standing behind a brand, which is the thing to establish before you assume two pots are covered separately.

Second, what the money earns while it sits there. Prices rose 2.6% in the twelve months to June 2026, so a balance paying nothing is quietly shrinking in what it can buy. Interest is taxable above the Personal Savings Allowance, which is £1,000 a year of interest for a basic-rate taxpayer, £500 for a higher-rate taxpayer and nothing at all for an additional-rate taxpayer. Rates change, and the rate a provider advertises may include a bonus that ends. Our guide to the best UK savings accounts goes through the account types, and our complete UK guide to ISAs covers the tax-free wrapper.


Credit Cards and the Month That Ran Out

Nobody carries a card balance because they are weak. They carry it because the money ran out before the month did and the card was there — which is precisely the moment the product is designed to be present for. What happens next is arithmetic rather than character: the card converts a one-off shortfall into a standing monthly cost, you pay interest on whatever you did not clear, and the minimum payment is a small proportion of the balance, so paying it faithfully can keep a debt alive for a very long time.

What to do about it is unglamorous, and it is the same as it has always been. Take the card out of your wallet. Take it out of your browser and your phone as well, because a saved card is the modern version of carrying one, and it is the version that gets used without a decision being made. And if the balance is not going down month on month, that is information rather than a verdict — it is the point at which free debt advice is worth more than anything an article can tell you.


The Bottom Line

Convert every monthly price into a year. Read twelve months of statements instead of one. Ring the provider before the contract rolls over rather than after. Keep the spending money somewhere with a bit of friction between it and you. None of it is clever, all of it works, and it works whether or not you feel like a different sort of person afterwards.

A thousand pounds a year is eighty-three pounds and change a month. If, having read the statements, you can find eighty-three pounds a month of things you had forgotten you were buying, then a thousand pounds is what you get. If you can only find thirty, take the thirty — that is three hundred and sixty pounds a year that used to leave without asking. Lifestyle creep is what happens to the difference if you don’t decide where it goes.
