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

📅 12 September 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 today to pay less — including how to find a cheaper tariff, simple habits that save real money, and why switching could be the smartest thing you do this year.

Let's be honest — energy bills have been an absolute nightmare for UK families over the past couple of years. Even though prices have come down from their eye-watering peaks, millions of households are still paying far more than they need to. The good news? There are real, practical steps you can take right now to shrink those bills — and some of them take less than 10 minutes. I'm Terry the Turtle, and I'm going to walk you through it all in plain English.

Why Your Current Tariff Might Be Costing You More Than You Think

Most people in the UK are sitting on their energy supplier's standard variable tariff — and that's almost never the cheapest option available. The energy market has been opening back up, with more fixed-rate deals appearing as competition returns. That means if you haven't checked what's out there recently, there's a very real chance you're leaving money on the table every single month.

A fixed tariff locks in your unit rate for a set period — usually 12 to 24 months. If that rate is lower than the current Ofgem price cap rate, you win. Right now, some fixed deals are coming in meaningfully below the price cap, which could save an average household anywhere from £150 to £500 per year depending on your usage and region.

Always check whether a fixed deal has exit fees before you sign up. Some do, some don't — and knowing this matters if your circumstances change.

How to Actually Find a Cheaper Energy Tariff

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

Step 1: Grab a recent energy bill. You need your annual usage in kWh for both gas and electricity — it's usually printed right there.

Step 2: Use a comparison service (like the one at TrueSaver) to see what deals are available in your area. Make sure you're comparing like-for-like — check whether quotes include a standing charge, as this can vary a lot between suppliers.

Step 3: Look at the total annual cost, not just the unit rate. A low unit rate with a high standing charge can end up costing you more overall.

Step 4: Read reviews for any supplier you haven't heard of. Cheap is great — but not if they're terrible at sorting out billing problems.

Switching energy supplier is free and takes around 15 to 20 minutes online. Your new supplier handles almost everything, and you won't have any gap in supply. It really is that straightforward.

Simple Habits That Cut Bills Without Cutting Comfort

Switching tariffs is the big win, but small daily habits add up too. You don't have to sit in the dark wearing three jumpers — just a few tweaks can make a genuine difference.

Turning your thermostat down by just one degree can save around £100 a year for an average home. Running your washing machine at 30°C instead of 60°C uses roughly 40% less electricity. And switching off devices on standby — things like TVs, games consoles, and phone chargers — can save another £45 to £80 annually according to the Energy Saving Trust.

Smart meters are also worth getting if you haven't already. They're free to install and show your real-time usage, which makes it much easier to spot where you're burning through energy unnecessarily. Ask your supplier — they're obliged to offer you one.

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

Lots of households are missing out on help they're genuinely entitled to. The Warm Home Discount gives eligible low-income households a £150 rebate off their electricity bill each year. Cold Weather Payments and the Winter Fuel Payment are available to pensioners and some benefit claimants. Your local council may also have funding available through the Great British Insulation Scheme, which can help with loft or cavity wall insulation — dramatically cutting the energy you need to heat your home in the first place.

Always check the government's website and speak to your supplier directly — many people are eligible and simply don't know it.

Terry's Top Tips

  • Compare tariffs at least once a year — the market changes, and loyalty rarely pays with energy suppliers.
  • Submit meter readings regularly — estimated bills can leave you with a nasty shock later on.
  • Check your insulation — a well-insulated home holds heat far better, meaning your boiler does less work.
  • Use off-peak electricity if you're on a smart meter — some tariffs charge less overnight, great for charging electric vehicles or running dishwashers.
  • Never ignore a debt with your supplier — contact them early and they must work with you on a repayment plan.

Energy bills don't have to feel overwhelming. A little bit of time spent comparing and checking your usage can put hundreds of pounds back in your pocket each year — and that's money your family can actually use. Head over to TrueSaver right now to compare energy tariffs in your area, check what support you might be entitled to, and start saving today. Go on — your future self will thank you for it.
