Energy — Potentially £200–400/Year
Since the energy crisis, most households are on their supplier's standard tariff, which tracks the Ofgem price cap. When fixed deals fall below the cap (which happens periodically as wholesale prices change), switching can save significant money. Check Uswitch, MoneySuperMarket, and the MSE energy club regularly. When switching, you need your current usage in kWh (on your bill) and meter readings. Switching takes around 3 weeks and is seamless — you keep the same pipes and wires, just a different company billing you.

Broadband — Save £100–300/Year
The single biggest broadband saving comes from not auto-renewing. At the end of a contract, providers typically move you to out-of-contract rates that are 30–60% more expensive. Call your provider and threaten to leave — the retentions team almost always has better deals than the standard tariff. If they won't budge, Openreach fibre (BT, Sky, TalkTalk, Plusnet, Vodafone) is all the same physical cable, so switching between them costs nothing in service quality. New customer deals are consistently cheaper than loyalty rates.
Mobile Phone — Save £200–600/Year
The biggest mobile money mistake is staying on a contract after it has ended. You continue paying the same amount but the handset is now paid off — you are effectively paying for a phone you already own. As soon as your contract ends, switch to a SIM-only deal. You can get 100GB of data on a 1-month rolling SIM from Three, SMARTY, or Lebara for £10–15/month. Keep your existing handset for another 2–3 years and redirect the saving. If you want a new phone, compare the total contract cost (monthly × months + upfront) against buying the handset outright and using a cheap SIM.
Car Insurance — Save £200–500/Year
Car insurance premiums are legally prohibited from charging renewal customers more than equivalent new customers — but you still need to shop around because different insurers price different profiles differently. Run a comparison on Compare the Market, Confused.com, and GoCompare — each shows different insurers. Check the insurers' own sites too (Direct Line and Aviva do not appear on all aggregators). The sweet spot for buying is 3 weeks before your renewal date — prices increase as the start date approaches. Telematics (black box) policies can save younger drivers 15–30%.

Home Insurance — Save £100–200/Year
Buildings and contents insurance auto-renews and premiums creep up every year. Run comparisons on the same sites as car insurance. Consider combining buildings and contents with the same insurer for a multi-policy discount. Check the excess carefully — a lower premium with a £500 excess is worse value if you make small claims. Make sure you declare the correct rebuild value (not the market value) for buildings insurance, and keep contents cover up to date — underinsurance is common and leaves you out of pocket at claim time.
Current Account Switching — Up to £200 in Free Cash
Banks regularly pay cash bonuses of £100–200 to new customers who switch via the Current Account Switch Service (CASS). The switch is guaranteed to complete in 7 working days and all direct debits and standing orders move automatically. Check MoneySavingExpert's regularly updated switching deals page. Beyond the cash bonus, compare ongoing benefits: Nationwide FlexPlus pays £13/month for phone, travel and breakdown insurance. Chase pays 1% cashback. Starling and Monzo offer excellent budgeting tools and fee-free overseas use.
Other Bills Worth Switching
TV and streaming: cancel subscriptions you have not used in 30 days — it is easier than you think to go without. Consider sharing family plans. Sky and Virgin routinely offer significant retention discounts to customers who call to cancel. Water rates cannot be switched (monopoly), but you can reduce bills with a water meter if you have fewer people than bedrooms. Gym membership: if unused, cancel and replace with free outdoor exercise or a cheaper council-run leisure centre.

Building a Switching Calendar
The biggest switching win is systemising it. Create a simple spreadsheet with every subscription and insurance, its current cost, its renewal date, and a reminder set 4 weeks before renewal. When the reminder triggers, spend 30 minutes comparing. People who do this consistently save £800–1,500/year. The work involved is around 10 hours per year total. That is an effective hourly rate of £80–150/hour for switching time — better than almost any investment.
Never use only one comparison site for insurance — each aggregator has different panel relationships and the cheapest deal is not always on the most famous site. Use at least two comparison sites and check the insurer directly. Also, check reviews before switching to an unfamiliar insurer — a cheap premium is worthless if claims are routinely disputed.
