Money Saving Tips UK 2025

Q: What is the quickest way to save money in the UK?

The quickest wins are: cancel unused subscriptions (average saving £50-100/month), switch energy tariff or supplier (save £100-300/year), switch bank account for a cash bonus (£100-200 one-off), and switch car and home insurance at renewal rather than auto-renewing (save £100-300/year). These four actions can save £400-900 in the first year with minimal ongoing effort.

Q: What are the best cashback websites in the UK?

The leading UK cashback websites in 2025 are TopCashback and Quidco. TopCashback consistently offers higher rates for new members. Both sites pay cash for purchases you make through their tracked links at retailers including Amazon, John Lewis, M&S, insurance providers, and energy companies. Always start at a cashback site before any significant online purchase.

Q: How much does the Rent-a-Room Scheme allow you to earn tax-free?

The Rent-a-Room Scheme allows UK homeowners and some tenants (with landlord permission) to earn up to £7,500 per year tax-free from renting a furnished room in their home. If two people share ownership, each can earn up to £3,750 tax-free. Income above the threshold is taxable but can still be very profitable, especially in London and other high-rent cities.

⚡ Energy: 5 Tips to Cut Your Bills

Get a smart meter avg £150/yr — Smart meters show real-time usage and prevent estimated bill errors. They are free to install. Seeing your usage live prompts most households to cut consumption by 5-10%. Book through your energy supplier's website.
Install TRVs (thermostatic radiator valves) avg £80-120/yr — Fit thermostatic radiator valves to every radiator. Turn them down in rooms you use less (spare bedroom, hallway). Each degree you lower in an unused room saves around £75/year. TRVs cost £10-15 each from B&Q or Amazon.
Compare and switch energy tariff every 12 months avg £100-300/yr — Use Uswitch, MoneySupermarket, or the Ofgem tariff comparison tool. In 2025, some fixed tariffs undercut the standard variable rate. Even a modest saving of £10/month adds up to £120/year.
Apply for the Warm Home Discount £150 one-off — The Warm Home Discount provides £150 off your energy bill if you are on a qualifying benefit (including Universal Credit) or have a low income and high energy costs. Apply through your energy supplier each autumn — the scheme is demand-limited so apply early.
Draught-proof your home for under £50 avg £60-100/yr — Draughts through letterboxes, window frames, and keyholes can waste 20% of your heating. Draught-excluding tape, door brushes, and keyhole covers cost under £50 in total and pay back within months. Chimney balloons (for unused fireplaces) save even more.

🛒 Food: 8 Tips to Cut Your Grocery Bill

Meal plan weekly before shopping avg £50/month — Planning meals for the week and shopping with a list cuts impulse buys and food waste. Research by WRAP (UK waste charity) shows UK households waste an average of £800/year in food. Meal planning can cut this significantly.
Shop the reduced section avg £20-40/month — Most supermarkets markdown perishables each evening (typically 5-7pm for large stores). Yellow sticker items are often 50-75% off. Cook and eat that evening, or freeze immediately. Many households save £20-40/month with zero change to diet quality.
Switch to own-brand products avg £30-60/month — Supermarket own-brand products are often manufactured in the same factories as branded equivalents. Switching staples (pasta, rice, tinned tomatoes, cereals, cleaning products) to own-brand can save 30-50% on those items. Aldi and Lidl consistently win taste tests against premium brands.
Batch cooking on weekends avg £40-80/month — Cook large batches of meals like bolognese, chilli, curries, and soups at the weekend. Freeze in portions. This eliminates expensive weekday convenience food and takeaways when you are too tired to cook. One cooking session provides 6-8 weekday meals.
Try a veg box or community scheme avg £20-30/month — Veg box schemes (Oddbox, Riverford, Abel & Cole) deliver seasonal or imperfect veg at lower cost than supermarkets. Oddbox, which sells cosmetically imperfect but perfectly edible produce, offers good value for vegetables and fruit.
Use the Olio app to collect free food variable — Olio connects people who have surplus food (including from supermarkets) with those who can use it. Many users collect free bakery items, vegetables, and packaged food from local supermarkets through Olio's food waste heroes programme.
Grow herbs on a windowsill avg £50-80/yr — Fresh supermarket herbs cost £1-2 per small bunch. A pot of basil, parsley, mint, or chives costs £1-2 and lasts for months if watered regularly. Growing 3-4 herbs saves most households £50-80/year and adds zero work to cooking.
Use Loyalty cards to their full potential avg £50-100/yr — Tesco Clubcard and Sainsbury's Nectar points have genuine value when redeemed strategically — particularly exchanged for restaurant or cinema vouchers at 2-3x face value. Scan at every shop. Use the Clubcard price feature which offers significant discounts to card holders.

🚆 Transport: 6 Tips to Cut Travel Costs

Buy a railcard for one-third off train travel avg £300-500/yr — 16-25, 26-30, two-together, and senior railcards all give 1/3 off most rail fares for £30/year. If you spend more than £90/year on rail travel, a railcard pays for itself. Buy through the Railcard app or trainline. Split tickets can save a further 20-40% on longer journeys.
Join the Cycle to Work scheme avg £200-400 one-off — The Cycle to Work scheme lets employees buy a bike and safety equipment through salary sacrifice, saving 32-42% (income tax + NI) on the cost. A £600 bike costs £350-400 through the scheme. Ask your HR department if your employer participates.
Use car sharing and Liftshare avg £50-150/month — Sharing commuting costs with colleagues via Liftshare or BlaBlaCar Daily can halve your fuel costs. Even sharing the commute with one colleague 3 days per week saves significant money on petrol and parking.
Check ULEZ and Clean Air Zone exemptions variable — If you live in or near London, Birmingham, or another city with a Clean Air Zone, check if you qualify for a scrappage or exemption scheme. Several thousand pounds of grants have been available to replace older vehicles. Check TfL's website and your local council.
Use a cashback fuel card avg £60-80/yr — Several UK credit cards offer 1-2% cashback on petrol and diesel. The American Express Everyday Cashback card offers up to 1% on all spending. Always pay the balance in full monthly to avoid interest charges negating the benefit.
Book travel in advance with advance tickets avg £100-300/yr — Advance train tickets can be 50-70% cheaper than walk-up fares. Book 6-8 weeks ahead for popular routes. For flexible travel, off-peak tickets avoid the peak premium. Trainline, Avanti West Coast, and Transpennine Express all offer advance ticket booking.

🛡️ Insurance: 5 Tips to Reduce Premiums

Always compare at renewal — never auto-renew avg £200-400/yr — Auto-renewing car and home insurance is one of the most expensive financial habits in the UK. Use comparison sites (Compare the Market, MoneySupermarket, Go Compare) every year. Switching saves an average of £200-300/year on car insurance and £100-200/year on home insurance.
Increase your voluntary excess avg £50-100/yr — Voluntarily increasing the excess you pay on a car insurance claim (say from £250 to £500) reduces your premium. Make sure you can genuinely afford the higher excess if you need to claim. Only sensible if you have an emergency fund.
Fit a telematics (black box) if you are a young driver avg £400-800/yr — Young drivers (17-25) typically pay the highest car insurance premiums. A telematics policy monitors your driving and rewards safe, low-mileage driving with significant discounts. Can save £400-800/year compared to standard young driver policies.
Bundle home and contents insurance avg £50-100/yr — Buying buildings and contents insurance from the same provider usually results in a multi-policy discount. Compare bundled quotes against separate policies — the combined deal is often but not always cheaper.
Check what your packaged bank account covers avg £100-200/yr — Premium bank accounts (Nationwide FlexPlus, NatWest Reward Silver) often include travel insurance, mobile phone insurance, and breakdown cover in the monthly fee. If you would otherwise buy these separately, the packaged account can offer better value.

🏦 Banking: 6 Tips to Get More From Your Money

Switch bank account for a cash bonus £100-200 one-off — Banks regularly offer £100-200 cash to switch using the 7-day Current Account Switch Service. Requirements typically include 2+ direct debits and a minimum monthly pay-in. See our bank account switching guide for current offers.
Use Chase UK for 1% cashback on debit spending avg £150-200/yr — Chase's current account offers 1% cashback on everyday debit card purchases for the first 12 months (capped at £15/month). For someone spending £1,000/month on their card, that is £120/year in cashback. Free account, no fees.
Move savings to a best-buy easy-access account avg £200-400/yr — High street bank savings accounts often pay minimal interest. Best-buy easy-access accounts (Marcus, Chip, Atom Bank) paid 4-5% AER in early 2026. On £10,000 savings, moving from 0.5% to 4.5% saves £400/year in lost interest.
Maximise your ISA allowance each year tax-free growth — Every UK adult can save up to £20,000/year in a tax-free ISA. Interest and investment gains in an ISA are completely tax-free. Even a Cash ISA earning 4% AER generates £800/year completely free of tax on a £20,000 balance.
Check if Premium Bonds suit you variable, tax-free — National Savings & Investments Premium Bonds offer a prize fund equivalent to approximately 4% AER (as of early 2026), with prizes completely tax-free. They are not suitable for small balances (you need £25,000+ to consistently receive prize rates approaching the advertised equivalent rate) but are excellent for higher-rate taxpayers.
Consider a Lifetime ISA for first-time buyers 25% government bonus — If you are aged 18-39 and saving for your first home, a Lifetime ISA adds a 25% government bonus on savings up to £4,000/year — a maximum £1,000 bonus per year. The account must be open for 12 months before you can use it, so open one today even if you only put in £1.

🛍️ Shopping: 6 Tips to Pay Less

Always start at a cashback site before online shopping avg £100-300/yr — TopCashback and Quidco track purchases made through their affiliate links and pay you a percentage back. Rates range from 0.5% on supermarkets to 10-15% on insurance and some retailers. Register both for free. Many people earn £150-300/year doing this with zero change to where they shop.
Use voucher code sites before checkout avg £50-100/yr — Before completing any online purchase, copy the retailer name into vouchercodes.co.uk or My Voucher Codes. Useful codes appear for a surprisingly wide range of retailers. The browser extension Honey automatically finds codes at checkout.
Buy and sell on eBay, Vinted, and Facebook Marketplace avg £200-500/yr — Selling clothes, electronics, and household items you no longer use can generate significant side income. Vinted has zero seller fees for clothing. Facebook Marketplace is ideal for bulky items (furniture, gym equipment). Many UK households have £500-2,000 worth of unused items at home.
Use OLIO and Freecycle for free items avg £100-200/yr — OLIO and Freecycle are platforms where people give away items for free. Furniture, plants, baby equipment, books, and kitchen items are regularly available. Check before buying anything new.
Wait for sales — but only for planned purchases avg £100-200/yr — The sales tactic only saves money if you were going to buy the item anyway. Create a list of planned purchases in advance, then wait for January sales, Black Friday, or end-of-season discounts. Do not buy sale items you did not plan to buy — that is spending, not saving.
Price track with CamelCamelCamel for Amazon avg £50-100/yr — CamelCamelCamel tracks Amazon price history and sends alerts when items drop to your target price. Many Amazon items fluctuate significantly in price. Waiting for a price drop can save 20-40% on electronics, kitchen appliances, and books.

📱 Subscriptions: 4 Tips to Reduce Monthly Outgoings

Audit all subscriptions monthly avg £50-150/yr — Go through your bank statement and list every recurring charge. The average UK adult has 8-12 active subscriptions. Cancel anything you have not actively used in the past month. Set a calendar reminder to review again in 3 months.
Share streaming services with family or friends avg £100-200/yr — Netflix, Disney+, and Apple TV+ all offer family or household plans. Sharing the cost with one or two other people (within the terms of service) can halve or third the monthly cost. A household plan at £18/month split three ways is £6/person instead of £18 each.
Use free tiers and ad-supported versions avg £60-100/yr — Spotify Free, YouTube (with ads), and BBC Sounds are high-quality free alternatives to paid services. If you mainly listen to music while commuting or cooking, Spotify Free with occasional ads may be perfectly adequate.
Negotiate with your broadband and mobile provider avg £80-150/yr — At the end of your contract, call your provider and ask for a better deal. Mention that you have been quoted £X from a competitor (look this up first). Most providers will offer a discount rather than lose you. BT, Sky, and Virgin Media all have retention teams with authority to offer deals not available to new customers.

🏠 Housing: 3 Tips for Renters and Homeowners

Take in a lodger under the Rent-a-Room Scheme up to £7,500/yr tax-free — UK homeowners and some renants (with landlord permission) can earn up to £7,500/year completely tax-free by renting a furnished room to a lodger under the government's Rent-a-Room Scheme. In London, a spare room can generate £700-1,200/month. This is one of the most financially transformative options available to UK homeowners.
Let out your driveway or garage when not in use avg £50-200/month — Apps like JustPark, YourParkingSpace, and Stashbee allow you to rent your driveway, parking space, or garage. Near train stations, town centres, or sports venues, spaces can command £50-200/month. The first £1,000/year from property rental is covered by the property income allowance and is tax-free.
Check your council tax band avg £200-400/yr if wrong — Around 400,000 UK properties are believed to be in the wrong (too high) council tax band. Band valuations were set in 1991 and many have never been corrected. Check your band on the Valuation Office Agency website and challenge it if your neighbours with similar-sized homes are in a lower band. Successful challenges result in backdated refunds.

💰 Benefits: 3 Tips to Claim What You Are Owed

Check your benefit entitlements with EntitledTo or Turn2Us potentially £1,000s/yr — An estimated £19 billion in benefits goes unclaimed in the UK each year. The two best free benefit calculators are EntitledTo.co.uk and Turn2Us.org.uk. Enter your details and they will identify every benefit you may be entitled to: Council Tax Reduction, Universal Credit, Pension Credit, Child Benefit, Carer's Allowance, and more.
Apply for free school meals if eligible avg £480-600/yr per child — Children whose families receive Universal Credit, Income Support, or other qualifying benefits are entitled to free school meals. In England, all children in Reception to Year 2 also qualify. Apply through your local council — it is free and takes 5-10 minutes. The saving per child is typically £480-600/year.
Check NHS prescription and dental charge exemptions avg £100-300/yr — Many UK residents are exempt from paying NHS prescription charges (£9.90 each in 2025) and dental charges. Exemptions include: under 16, in full-time education, pregnant or recently given birth, on certain benefits, over 60, or with certain medical conditions.

Contribute enough to get full employer pension match 100% instant return — If your employer matches pension contributions up to 5% of your salary and you only contribute 3%, you are leaving free money on the table. Increasing your contribution by 2% to get the full employer match is an immediate 100% return on that money. No investment can beat that risk-free return.
Open a Stocks and Shares ISA and invest regularly long-term wealth — Investing as little as £100/month in a low-cost index fund via a Stocks and Shares ISA (try Vanguard, Freetrade, or InvestEngine) grows significantly over time. £100/month for 30 years at 7% average annual return becomes approximately £120,000. All growth is completely tax-free within the ISA wrapper.
Use the Moneybox or round-up savings feature avg £200-500/yr — Apps like Moneybox round up every card transaction to the nearest pound and invest or save the difference. Spending £2.70 on a coffee creates a 30p saving. The average user saves £200-500/year without noticing. Monzo and Starling have similar built-in round-up features that move savings into pots automatically.

Greater savings come from reducing consumption (smart meter, TRVs, draught-proofing) rather than supplier switching, which could save £150-300/year with one-off investment of £50-200 in home improvements.

Is the Help to Save account still available in 2025?

Yes. Help to Save is a government savings account for working people on Universal Credit or Working Tax Credit. You can save £1-50 per month and the government adds a 50% bonus on the highest balance reached after years 2 and 4.

The maximum government bonus is £1,200 over 4 years. Open an account at Gov.uk — it takes 5-10 minutes. Even if you only save a small amount, the 50% bonus makes this one of the best guaranteed returns available in the UK.
