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

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

Energy bills are still squeezing millions of UK households. Terry the Turtle breaks down the simple steps you can take today to slash what you pay — no jargon, no fuss, just real savings.

Let's be honest — energy bills have been an absolute nightmare for UK families over the past few years. Even though prices have come down from their scary peak, millions of households are still paying far more than they need to. The good news? There are real, practical things you can do right now to cut what you're spending — and some of them take less than five minutes. I'm Terry the Turtle, TrueSaver's friendly financial expert, and I'm going to walk you through exactly what to do.

First Things First: Know What You're Actually Paying

Before you can save anything, you need to know your starting point. Dig out a recent energy bill or log into your supplier's app and find your current tariff name and the unit rates you're paying for gas and electricity. Most people have no idea what they're on — and that's exactly how suppliers like it. The energy price cap set by Ofgem changes every three months, so what was a decent deal six months ago might be expensive now. Once you know your numbers, you're ready to take action. It takes five minutes and could be worth hundreds of pounds.

The Big One: Should You Fix Your Energy Tariff Right Now?

For a long time, fixed-rate tariffs disappeared almost completely. But they're back — and some of them are genuinely worth looking at. A fixed tariff means you lock in a set unit rate for a period of time, usually 12 to 24 months. This protects you if prices rise, but means you might miss out if prices fall. So how do you decide? Here's the simple rule: if you can find a fixed deal that's only slightly above the current price cap rate, it's often worth considering for the peace of mind alone. Energy experts are currently expecting prices to stay fairly flat or nudge upwards, which makes fixing more attractive than it's been in a while. Use a comparison tool to see what's available in your area — and always check for exit fees before you sign up, so you're not trapped if something better comes along.

Switch Supplier and Actually Save Real Money

Switching energy supplier used to be a faff. These days, it's remarkably straightforward and the whole process can take under 10 minutes online. Your new supplier handles pretty much everything, and you're protected by Ofgem rules that make the process safe and simple. When you compare deals, look at the annual estimated cost based on typical household usage — that's the fairest way to compare. Don't just look at the unit rate; check the standing charge too, because that's the daily fee you pay just for being connected. Some tariffs have low unit rates but high standing charges, or vice versa. The combination of both tells the real story. Households that switch from a standard variable tariff to a competitive fixed deal are saving anywhere from £150 to £500 a year right now.

Quick Wins at Home That Add Up Faster Than You Think

Switching tariffs is the biggest win, but small changes at home genuinely do add up. Turning your boiler flow temperature down to around 60 degrees can cut your gas bill by up to 8% with no loss of heating comfort — your heating engineer can show you how, or there are simple guides online. Washing clothes at 30 degrees instead of 60 uses around 40% less electricity per wash. Draught-proofing your windows and doors is cheap to do yourself and can save £60 a year or more. And if you haven't already, switching to LED bulbs throughout your home could save around £65 a year on lighting alone. None of these things are glamorous, but together they make a genuine dent in your bills.

Terry's Top Tips

  • Submit regular meter readings. If your supplier estimates your usage, you could end up overpaying or building up unexpected debt. A quick reading every month keeps things accurate.
  • Check if you qualify for extra help. The Warm Home Discount, Winter Fuel Payment, and Cold Weather Payment are all available to eligible households — don't leave free money on the table.
  • Set a calendar reminder to compare tariffs. Do it every three months when the Ofgem price cap updates. Markets change fast and staying on top of it pays off.
  • Don't assume loyalty pays. Long-standing customers are often on the worst deals. New customers frequently get better rates — so always shop around.
  • Look at your direct debit amount. Many suppliers set these too high and then sit on your money. If you're in credit, ask for a refund and adjust your payments down.

Energy bills don't have to keep draining your bank account. Whether you switch tariff, fix your rate, or just make a few smart changes at home, every pound saved is a pound back in your pocket where it belongs. Ready to see what you could save?
