Are You Overpaying on Energy in 2026? Here's How to Find Out

23 March 2026 · 4 min read

Energy bills have been one of the biggest household expenses in the UK for several years now, and 2026 is no different. With the Ofgem energy price cap set at £1,641 per year for a typical dual-fuel household from April 2026, millions of people are paying more than they need to — without even realising it.

The price cap doesn't limit your total bill. It caps the maximum unit rate and standing charge your supplier can charge if you're on a standard variable tariff (SVT). If you use more energy than average, you'll pay more than £1,641. And if you haven't switched in a while, you're almost certainly on an SVT — the most expensive type of tariff.

Standard Variable Tariffs vs Fixed Deals

When your fixed energy deal ends, your supplier automatically moves you onto their standard variable tariff. This is typically the most expensive rate they offer. It's designed to be a default, not a good deal.

Fixed deals, on the other hand, lock in your unit rate for 12 or 24 months. Right now, some of the best fixed tariffs are priced below the price cap, meaning you could save a significant amount by switching away from your SVT. The difference can be anywhere from £100 to £300 or more per year, depending on your usage.

Signs You're Overpaying

You're likely overpaying on energy if any of the following apply to you:

• You haven't switched energy supplier or tariff in the last two years
• You're not currently on a fixed-rate deal (check your latest bill — it will say "variable" or "standard")
• Your annual energy spend is above £1,641 for a typical three-bedroom house
• You've never compared your unit rate against what's available on the market
• You moved into a new property and never changed the default energy supplier

How to Check What You're Actually Paying

The two numbers that matter most on your energy bill are your unit rate (the cost per kilowatt-hour of gas and electricity you use) and your standing charge (a daily fixed fee just for having a supply connected).

Find these on your latest bill or your online account. Then compare them against the best deals currently available. If your unit rate is higher than the cheapest fixed deals on the market, you're leaving money on the table.

Switching Is Easier Than You Think

Many people put off switching because they assume it's complicated. In reality, it takes about five minutes. You don't need to call anyone, no engineer needs to visit, and your supply is never interrupted. The switch typically completes within five working days, and your new supplier handles everything — including contacting your old one.

If you're on a standard variable tariff, there are no exit fees. If you're on a fixed deal that hasn't ended yet, check whether the savings from switching outweigh any early exit penalty (usually £30-£50 per fuel).
