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

📅 17 August 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 how to find cheaper tariffs, reduce what you use, and keep more money in your pocket — starting today.

If you're like most UK families, energy bills feel like a never-ending headache. Even as wholesale prices have shifted, millions of households are still paying more than they need to — simply because they haven't had the time, tools, or confidence to shop around. The good news? A few straightforward moves could save you hundreds of pounds every single year. Let's get into it.

Why Right Now Is Actually a Great Time to Switch

For a long time, switching energy suppliers felt pointless because fixed-rate deals had vanished from the market. But they're back! More and more suppliers are offering competitive fixed tariffs that could lock you in below — or very close to — the current Ofgem price cap. That matters because if wholesale energy prices creep back up (and they very well might), you'll be protected. Nobody wants another nasty bill shock like we saw in 2022.

The Ofgem price cap changes every quarter, so your current standard variable tariff goes up and down with it. A good fixed deal gives you certainty, which makes budgeting so much easier for ordinary families. It's not about gambling on prices — it's about knowing exactly what's coming out of your account each month.

How to Find a Cheaper Tariff in Under 10 Minutes

This is easier than most people think. Here's what to do:

Step 1 — Grab your latest energy bill. You'll need your annual usage figures in kWh for both gas and electricity. Don't worry if you can't find them — most suppliers let you log in online or via their app to get this information instantly.

Step 2 — Use a comparison tool. Pop your details into a trusted energy comparison site (like the one here at TrueSaver!) and within minutes you'll see a ranked list of deals tailored to your actual usage. Always compare on annual cost, not just unit rates, because standing charges can make a big difference.

Step 3 — Check exit fees first. If you're already on a fixed tariff, check whether you'll be charged for leaving early. Sometimes a small exit fee is still worth it if the new deal saves you significantly more over the year.

Step 4 — Switch! The whole process is handled digitally these days. Your new supplier contacts your old one, and you won't lose supply for even a single second. It typically takes around three weeks.

Smart Ways to Actually Use Less Energy

Switching tariff is step one, but using less energy is where the long-term savings really add up. None of this requires spending big money on gadgets or home improvements either.

Turning your thermostat down by just one degree can save around £100 a year, according to the Energy Saving Trust. Washing clothes at 30°C instead of 60°C uses roughly 40% less electricity. Switching off devices completely rather than leaving them on standby can save another £55 or so annually. These small habit changes cost nothing and add up fast.

If you have a smart meter, use it! The real-time display shows you exactly which appliances are guzzling the most energy. Many families are genuinely shocked when they see what their old tumble dryer or electric shower is costing them per hour.

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

Thousands of UK households are missing out on support they're actually entitled to. The Warm Home Discount gives eligible low-income households £150 off their electricity bill. The Winter Fuel Payment helps older households. And if you're on certain benefits, you may qualify for the Energy Company Obligation (ECO4) scheme, which can fund free insulation or even a new boiler.

It's always worth checking — you might be leaving money on the table without knowing it.

Terry's Top Tips

  • Compare every year, at minimum. Loyalty rarely pays with energy suppliers. Even if you're happy, checking the market once a year takes minutes and could save you hundreds.
  • Always read your meter before switching. This ensures your final bill from your old supplier is accurate and you're not overcharged.
  • Consider a fixed deal for peace of mind. If the current fixed rates are close to the price cap, locking in protects you from future price rises.
  • Check if you qualify for any government support. Head to Gov.uk or call your supplier directly — it's free to ask.
  • Use a smart meter if you don't have one already. Ask your supplier for a free installation — it's a brilliant tool for spotting where your money is going.

You work hard for your money, and your energy bill shouldn't be taking more of it than necessary. Even making just one or two of these changes could put a few hundred pounds back in your pocket over the coming year. Ready to see what you could save?
