Energy remains one of the largest household expenses in the UK, and despite greater market stability than in previous years, millions of households are still paying more than they need to for gas and electricity.
The reason is simple: energy prices vary widely by supplier, tariff, region, and usage — and those differences are not always obvious.
In 2026, competitive fixed tariffs have returned, green energy options are more affordable, and suppliers are actively trying to attract new customers. However, default and out-of-contract tariffs remain significantly more expensive, meaning households that do not regularly compare energy prices are often overpaying by hundreds of pounds each year.

This complete consumer guide explains how energy pricing works, what affects gas and electricity costs, how to compare accurately, switch safely, and avoid common costly mistakes.
To compare energy prices properly, it's important to understand how bills are calculated. Every energy tariff is built from the same core components.
The unit rate is the price you pay for each kilowatt-hour (kWh) of energy used.
Electricity has a higher unit rate. Gas is cheaper per kWh but usually used in larger volumes. For most households, gas still accounts for the biggest share of total energy consumption, particularly in homes with gas central heating.
Standing charges are fixed daily costs that apply regardless of how much energy you use. They cover:
Standing charges vary by region and supplier and can significantly affect total costs, especially for low-usage households.
Most UK households are on one of the following:
Energy prices are not uniform across the UK. Two households using the same amount of energy can pay very different amounts depending on location.
Fixed tariffs remain popular in 2026 because they offer stability and protection against price rises.
Variable tariffs change over time and are usually more expensive over a full year.
Most UK households choose dual fuel, where gas and electricity are supplied by the same company.
For very low gas consumption households
In areas with strong supplier competition
When green or specialist suppliers offer better value
To get an accurate comparison and avoid misleading results, follow these essential steps:
Base comparisons on your actual electricity and gas consumption from recent bills, not estimates.
Always include standing charges and full tariff costs, not just unit rates.
Review contract length, exit fees, and renewal terms before committing.
Price matters, but billing accuracy and customer service also count.
Green energy is no longer a premium option. In 2026, many renewable tariffs are priced competitively with standard deals.
In 2026, switching to renewable energy typically adds less than £5/month to the average household bill, and often costs the same as standard tariffs.
Sourced from wind, solar, and hydro power
Gas usage balanced with carbon reduction projects
No significant price increase vs standard tariffs
For environmentally conscious households, switching to green energy can often be done without paying more, making it an easy choice for those looking to reduce their carbon footprint.
Many households overpay due to avoidable mistakes. Here are the most common pitfalls:
Remaining on standard variable tariffs for too long
Focusing only on unit rates, not total costs
Believing existing customers get better deals
At least once every 12 months, or when your fixed tariff ends. Regular comparison ensures you're always on a competitive deal.
No. Switching energy suppliers does not affect your credit rating. Energy switching is considered a normal consumer activity.
Yes, as long as they pay the energy bills and have a separate meter. Renters have the same switching rights as homeowners.

Energy price comparison remains one of the most effective ways to reduce household bills in the UK. In 2026, households that regularly review their tariffs often save £200–£500 per year.
With competitive fixed deals available, green tariffs becoming more affordable, and regional pricing differences increasing, comparing energy prices is no longer optional — it is essential.
