Cut Your Energy Bills by Up to £500 This Year — Here's Exactly How to Do It

📅 21 June 2026⏱️ 5 min read✍️ Terry the Turtle

Energy bills are still one of the biggest drains on UK household budgets. Terry the Turtle breaks down exactly what you can do right now to find cheaper tariffs and trim hundreds off your annual bill.

Let's be honest — energy bills have been eye-watering for UK families over the past few years. Even with prices settling down a little, the average household is still spending over £1,700 a year just to keep the lights on and the heating running. That's a huge chunk of most people's income, and the good news is that you don't have to just accept it. There are real, practical steps you can take right now to spend less — and I'm going to walk you through every single one of them.

The Energy Market Is Opening Up Again — and That's Great News for You

For a while, fixed-rate energy deals pretty much disappeared from the market. But they're back, and some of them are genuinely good value. Energy suppliers are competing for your business again, which means if you haven't checked what's available recently, you could be leaving real money on the table.

Most people sitting on their supplier's standard variable tariff (that's the default rate you get if you've never switched or your fixed deal ended) are paying more than they need to. Switching to a competitive fixed deal could save you anywhere from £150 to £500 depending on your usage and current tariff. The switch itself is straightforward — your new supplier handles almost everything, and your gas and electricity never actually gets cut off during the process.

How to Find the Cheapest Tariff for Your Home

The single most powerful thing you can do is use an independent comparison tool. Don't just call your current supplier and ask if they have anything cheaper — they'll only show you their own deals. An independent comparison shows you the whole market.

Before you start comparing, grab a recent energy bill and note down your annual usage in kilowatt hours (kWh) — there'll be separate figures for gas and electricity. This makes any comparison far more accurate than just using national averages, which might not reflect how your household actually uses energy.

When comparing, look beyond just the unit rate. Check the standing charge too — that's the fixed daily fee you pay regardless of how much energy you use. A tariff with a low unit rate but a high standing charge might not actually be cheaper for your household.

Small Changes at Home That Add Up to Big Savings

Switching tariff is the big win, but don't overlook the everyday habits that quietly drain your wallet. Here are some changes that genuinely move the needle:

  • Turn your thermostat down by just 1°C — this alone can cut your heating bill by around 10%, saving roughly £115 a year for a typical home.
  • Switch to LED bulbs everywhere — if you haven't already, this is one of the easiest wins going. LEDs use up to 90% less energy than old-style bulbs.
  • Wash clothes at 30°C instead of 40°C — modern detergents work just as well at lower temperatures, and you'll use around 40% less electricity per wash.
  • Check your boiler pressure and get it serviced — an inefficient boiler works harder and costs more to run. An annual service keeps it running at its best.

Don't Miss Out on Help You're Entitled To

Millions of UK households are eligible for financial support with energy costs but never claim it. The Warm Home Discount gives eligible households £150 off their electricity bill each year. If you're on certain benefits or have a low income, you may qualify automatically — but sometimes you need to apply, so check with your supplier directly.

Cold Weather Payments and the Winter Fuel Payment for pensioners are also worth knowing about. And if you're really struggling, most suppliers have hardship funds and flexible payment plans — they'd rather help you than see you fall into debt, so don't be afraid to pick up the phone.

Terry's Top Tips

  • 🐢 Compare the whole market, not just your current supplier's deals — use an independent comparison tool like TrueSaver.
  • 🐢 Submit regular meter readings so you're billed for what you actually use, not an estimate that could leave you in debt or credit.
  • 🐢 Set a reminder to review your tariff every 12 months — the best deal today won't necessarily be the best deal next year.
  • 🐢 Check your eligibility for the Warm Home Discount — £150 off your bill is worth five minutes of your time.
  • 🐢 Don't ignore smart meters — they help you see exactly where your energy is going so you can cut waste with confidence.

Energy is one of those bills that feels fixed and unavoidable — but it really isn't. A few smart moves could put hundreds of pounds back in your pocket this year. Head over to TrueSaver right now to compare energy tariffs in your area, check what support you might be entitled to, and take the first step towards a cheaper bill. It only takes a few minutes, and the savings can last for years. You've got this! 🐢
