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

📅 22 September 2026⏱️ 4 min read✍️ Terry the Turtle

Energy bills are still one of the biggest drains on family budgets across the UK. Terry the Turtle breaks down exactly what you can do TODAY to pay less — no complicated jargon, just straight-talking advice that could save you hundreds of pounds.

Let's be honest — energy bills have given millions of UK families a real headache over the past couple of years. Even though prices have come down from their scary peaks, the average household is still paying far more than they were just a few years ago. The good news? There are real, practical steps you can take RIGHT NOW to trim what you're paying. I'm Terry the Turtle, TrueSaver's friendly financial expert, and I'm here to walk you through it — nice and simply.

First Things First: Check Whether You're On a Good Deal

Most people in the UK are sitting on their energy supplier's standard variable tariff — and that's almost never the cheapest option available. Think of it like staying loyal to one supermarket when the one down the road has everything on sale. The energy market has started opening up again, with fixed-rate tariffs returning that can lock in your price for one or two years. That means no nasty surprises if wholesale prices spike again.

Start by finding out which tariff you're currently on. Check your latest bill or log into your supplier's app or website. Once you know what you're paying per unit (in pence per kilowatt hour, or p/kWh) and what your standing charge is, you've got everything you need to compare deals properly.

How to Compare and Switch Energy Tariffs Without the Headache

Switching energy suppliers sounds scarier than it is. In reality, your gas and electricity supply won't be interrupted — it's just the company billing you that changes. The whole process usually takes around three weeks and you don't need to do anything physical at all.

Here's what to do: grab a recent energy bill so you know your annual usage in kilowatt hours (kWh). Then use a comparison tool (like the one right here at TrueSaver) to see which tariffs beat what you're currently paying. Look at the total annual cost rather than just the unit rate — some tariffs have lower unit rates but higher standing charges, so always compare the full picture.

If fixed deals feel too uncertain right now, some suppliers also offer cheaper variable tariffs than the big household names. Even shaving £200–£300 off your annual bill is well worth 20 minutes of your time.

Don't Overlook These Free Ways to Use Less Energy

Switching tariff is brilliant, but using less energy saves you money no matter who you're with. A few small habit changes can add up to serious savings over a year:

  • Turning your thermostat down by just 1°C can cut your heating bill by around 10% — that's potentially £100 or more back in your pocket.
  • Washing clothes at 30°C instead of 40°C uses around 40% less electricity per cycle.
  • Switching off devices on standby across your home could save you around £55 a year, according to the Energy Saving Trust.
  • A smart meter won't save you money on its own, but seeing your usage in real time genuinely helps most families spot where they're wasting energy.

Also worth knowing: if you're on a low income or receive certain benefits, you may qualify for the Warm Home Discount — a £150 credit applied directly to your electricity bill. Check your eligibility with your current supplier or on the government's website.

Terry's Top Tips

  • Submit meter readings regularly. Estimated bills can leave you paying too much (or create a nasty catch-up bill later). A real reading keeps things accurate.
  • Set a reminder to review your tariff every 12 months. Fixed deals end, prices change — make it a yearly habit, like renewing your car insurance.
  • Don't assume loyalty pays off. Long-standing customers rarely get the best deals. New tariffs are often reserved for switchers.
  • Check for grants and schemes. The ECO4 scheme may fund free insulation or a new boiler for eligible households — it's worth a quick check.
  • Bundle your comparison. While you're at it, check your broadband and insurance too. Comparison sites like TrueSaver let you tackle multiple bills in one go.

Energy bills don't have to feel like something that just happens to you. With a little time and the right tools, you can take back control and keep more of your hard-earned money where it belongs — in your pocket.
