Is Aldi/Lidl really that much cheaper than Tesco/Sainsbury?

Yes. Independent comparison studies (Which?, MSE) consistently show 25-40% lower equivalent basket prices at Aldi/Lidl vs Tesco/Sainsbury/Morrisons. For a £200/week family shop, that's £50-£80/week saved = £2,600-£4,160/year. Brand-equivalent products often manufactured in same facilities.

How do I check if my council tax band is wrong?

Find your address on the Valuation Office Agency (VOA) website: gov.uk/council-tax-bands. Check your band. Then check 3-5 nearby similar-sized properties.

Are bank switching bonuses worth the hassle?

Yes - £150-£200 free money for ~1 hour of admin. Best 2026 offers from Lloyds, NatWest, Santander, First Direct. Process: open new account, set up 2+ direct debits, sometimes deposit minimum. Bonus paid in 3-30 days. Don't close old account - keep open for credit history. Can repeat every 12-18 months at different banks.

Should I cancel all my subscriptions?

No - keep ones you use weekly. The audit exercise: list every recurring payment from your bank statement for 3 months. Mark: "use weekly", "use monthly", "use rarely", "haven't used in 3+ months". Cancel last two categories. Typical UK adult finds £30-£80/month in unused subscriptions.

Is selling my car realistic?

Only in dense urban areas with good public transport. Total car cost (insurance + tax + fuel + depreciation + maintenance + parking) typically £350-£600/month for typical UK car. If train + occasional rental + Uber costs less, selling makes sense. For most rural / suburban UK, car needed - focus other hacks instead.

How do energy time-of-use tariffs work?

Standard tariff: same price 24/7 (~25p/kWh). Time-of-use tariff: cheap off-peak (typically midnight-7am, 10-12p/kWh) + expensive peak (~30p/kWh). Run dishwasher, washing machine, EV charging overnight. Avoid: cooking + heavy electricity use during peak hours. Net saving: £10-£40/month for households with shiftable load.
