If you are building a budgeting system and want a clear sequence for saving and spending control, start with the Budgeting Hub.
Small savings add up over time. As a worked example, putting away an extra £200 a month is £2,400 a year, or £12,000 over five years before interest. Here are 50 practical, UK-specific ways to cut your spending without sacrificing quality of life.
Bills and Utilities
1. Switch Energy Tariff
When your fixed deal ends, compare tariffs on comparison sites. The gap between the cheapest and most expensive tariffs depends on your usage and region.
2. Switch Broadband
Broadband is one of the most overpaid bills. When your contract ends, call to negotiate or switch. The saving depends on your current price and the deals available.
3. Negotiate Your Mobile Contract
SIM-only deals are significantly cheaper than handset contracts. A SIM-only plan usually costs less per month than a contract that includes a phone.
4. Review Insurance Annually
Comparing car and home insurance quotes at renewal, rather than auto-renewing, is one way to check you are not overpaying.
5. Cancel Unused Subscriptions
Subscriptions add up across a year. Audit every recurring payment and cancel anything you don’t actively use.
6. Reduce Water Usage
Install a water meter if you use less than your rateable value suggests. Reduce shower time and fix dripping taps.
7. Claim Council Tax Discounts
Living alone? You get 25% off council tax. Students, carers, and people with severe mental impairment may qualify for further discounts. See our council tax guide.
Food and Groceries
8. Meal Plan Weekly
Planning meals before shopping eliminates impulse buys and reduces food waste. WRAP says food waste costs a four-person household around £1,000 per year in food bought but not eaten (WRAP release, November 2023, 2021 data).
9. Shop at Budget Supermarkets
In Which?’s September comparison of 93 items, Aldi cost £159.48 and Lidl £161.84, against £193.45 at Tesco and £195.01 at Sainsbury’s (without loyalty prices). That is about 17.5% to 18% cheaper at Aldi and about 16% to 17% cheaper at Lidl (computed from the basket totals).
10. Use Supermarket Loyalty Apps
Tesco Clubcard prices, Nectar prices, and Lidl Plus offers give member-only prices on selected items. In Which?’s September analysis, a 93-item list cost £187.71 at Tesco with Clubcard Prices and £193.45 without (about 3% less, computed), so compare against other shops.
11. Buy Own-Brand Products
Supermarket own-brands often cost less than branded products. In Which?’s blind taste tests, six of the eight groceries tested showed that swapping to own-brands could save shoppers hundreds of pounds a year without a drop in taste.
12. Batch Cook
Cook large batches and freeze portions. Saves money on ingredients and reduces the temptation to order takeaways.
13. Reduce Food Waste
WRAP puts the cost of household food waste at around £1,000 a year for a four-person household. Use leftovers, freeze what you won’t eat in time, and understand date labels (best before ≠ use by).
14. Use Too Good To Go
Get “magic bags” of surplus food from restaurants and supermarkets at a fraction of the retail price.
Transport
15. Walk or Cycle Short Journeys
Many car trips are under 2 miles. Walking saves fuel and improves health.
16. Use a Railcard
The 16–25, 26–30, Two Together and Family & Friends Railcards each save one-third on most train tickets, with minimum fare and time restrictions on some. Each costs £35 for a one-year card.
17. Compare Fuel Prices
Use PetrolPrices or Google Maps to find the cheapest fuel nearby. Supermarket fuel stations are often cheapest.
18. Consider Car Sharing
If you commute by car, platforms like Liftshare match you with others making the same journey.
19. Drive Efficiently
Gentle acceleration, maintaining tyre pressure, and removing roof racks when not in use can help fuel economy.
20. Challenge the Need for a Second Car
A second car adds insurance, tax, fuel, servicing and depreciation costs. Could public transport, cycling, or car hire cover the gap?
Shopping and Spending
21. Use Cashback Sites
TopCashback and Quidco pay you cash back on purchases from hundreds of retailers. What you earn depends on how much you spend through them.
22. Wait 48 Hours Before Big Purchases
Impulse buys account for a significant portion of overspending. Waiting separates wants from needs.
23. Buy Second-Hand
Facebook Marketplace, Vinted, and charity shops offer clothes, furniture, and electrnics at a fraction of new prices.
24. Use the Library
Free books, audiobooks, magazines, and often free access to digital resources like newspapers.
25. Sell What You Don’t Use
Declutter and sell on eBay, Vinted, or Facebook Marketplace. Unused items can be worth selling.
Housing
26. Remortgage When Your Deal Ends
Moving from your lender’s SVR to a new fixed deal can lower your monthly payment, depending on the rates available. See our remortgaging guide.
27. Consider Overpaying Your Mortgage
Even small overpayments reduce total interest significantly. See our mortgage overpayment calculator.
28. Rent Out a Spare Room
The Rent a Room Scheme lets you earn up to £7,500 a year tax-free from letting out furnished accommodation in your home, or £3,750 if you share the income with someone else.
29. Improve Energy Efficiency
Draught-proofing, loft insulation, and LED bulbs reduce energy bills. Many can be done cheaply or with government grants.
30. Reduce Heating Costs
Turn your thermostat down by 1°C, which can lower heating costs. Use a programmable thermostat to heat only when needed.
Financial Products
31. Switch to a Reward Current Account
Some current accounts offer cashback on bills or higher interest on balances.
32. Use a Credit Card for Cashback
Cashback credit cards return a percentage of spending, and the rate varies by card. Pay in full monthly to avoid interest. Use our 0% credit card guide.
33. Move Savings to Better Rates
Compare savings rates and move your money. The difference between the worst and best savings accounts can be significant, so check current rates.
34. Use Your ISA Allowance
ISA returns are tax-free — especially valuable for higher rate taxpayers.
35. Check Your Tax Code
An incorrect tax code means you may be overpaying tax. Check via your HMRC personal tax account.
