How to Find the Cheapest Energy Tariff in the UK: Your Guide

Energy bills are a significant outgoing for most UK households, and with prices fluctuating, finding the cheapest energy tariff is more important than ever. While the energy market has experienced considerable upheaval in recent years, opportunities to save still exist by understanding your options and actively seeking out better deals.

This guide will equip you with the knowledge and tools to navigate the energy market, compare tariffs, and ultimately secure the cheapest energy deal for your home.

Understanding Energy Tariffs: Key Terms

Before diving into comparisons, it's crucial to understand the basic terminology associated with energy tariffs. This will help you make an informed decision.

• Unit Rate: This is the price you pay for each unit of electricity (kWh - kilowatt-hour) or gas (kWh) you use. A lower unit rate generally means lower bills if your usage is high.
• Standing Charge: A fixed daily charge that you pay regardless of how much energy you use. This covers the cost of supplying energy to your home, maintaining the network, and meter reading. It's often non-negotiable but can vary between tariffs.
• Fixed Tariff: Your unit rates and standing charges are locked in for a set period, typically 12 or 24 months. This offers predictability and protects you from price increases, but you won't benefit if prices drop.
• Variable Tariff: Your unit rates and standing charges can go up or down according to market conditions. While this offers flexibility, it also means your bills might fluctuate, and you could pay more if prices rise.
• Standard Variable Tariff (SVT): This is the default tariff you'll be placed on if your fixed deal ends and you don't switch, or if you've never switched. SVTs are usually among the most expensive tariffs regulated by the energy price cap.
• Dual Fuel: Buying both your electricity and gas from the same supplier, often offering a discount compared to buying them separately.
• Green/Renewable Energy Tariffs: These tariffs guarantee that a certain percentage, often 100%, of the electricity supplied matches the amount generated from renewable sources. Some suppliers generate their own renewable energy, while others buy Renewable Energy Guarantees of Origin (REGOs) certificates.

Why Finding the Cheapest Energy Tariff Matters

The difference between a standard variable tariff and a competitive fixed deal can amount to hundreds of pounds per year. Even small savings on your energy bills can add up, especially during periods of high usage like winter. By actively seeking out the cheapest energy tariff, you're not just saving money; you're taking control of your household budget and ensuring you're not overpaying for an essential service.

The Energy Price Cap: What It Means for You

The energy price cap, set by the energy regulator Ofgem, limits the amount suppliers can charge per unit of energy and per day for the standing charge on standard variable tariffs. It's reviewed quarterly (previously every six months) and announced a few weeks before it comes into effect.

Important Note: The price cap isn't a cap on your total bill; it's a cap on the unit rates and standing charges. The more energy you use, the more you will pay, even if you are on the price cap protected standard variable tariff. While it protects customers on SVTs from excessive price hikes, fixed deals can sometimes be cheaper than the price cap level, especially when the cap is high or expected to fall.

How to Find the Cheapest Energy Tariff UK: Step-by-Step

Finding a cheaper deal requires a bit of research and comparison. Here's how to do it:

1. Gather Your Current Energy Information

To get an accurate comparison, you'll need the following:

• Your latest energy bill: This will show your current supplier, tariff name, and most importantly, your annual energy consumption in kWh for both gas and electricity. If you don't have a bill, your supplier can provide this, or you can estimate using an online calculator (though this is less accurate).
• Your postcode: Energy prices can vary slightly by region.
• Your payment method: Direct Debit is usually the cheapest option.
• Your meter type: (e.g., standard, smart meter, Economy 7).

2. Use Ofgem-Accredited Comparison Sites

Ofgem, the energy regulator, accredits a number of independent price comparison websites. These sites are obligated to provide impartial and comprehensive results. Using them is often the quickest and most effective way to compare a wide range of tariffs from different suppliers.

Popular Ofgem-accredited comparison sites include:

• MoneySuperMarket
• Uswitch
• Compare the Market
• GoCompare

When using comparison sites, make sure to:

• Input accurate usage figures: Using your actual annual consumption (from your bill) will yield the most precise results.
• Filter results: You can often filter by tariff type (fixed, variable), green tariffs, customer service ratings, and more.
• Consider exit fees: If you're currently on a fixed tariff, check if there are exit fees for switching early. Factor these into your savings calculation.

3. Check Supplier Direct Tariffs

While comparison sites are excellent, some smaller suppliers or special tariffs might not always be listed everywhere. It's worth briefly checking the websites of major suppliers (e.g., British Gas, E.ON Next, Octopus Energy, OVO Energy, Scottish Power, EDF) and smaller, often challenger brands, directly to see if they have any exclusive deals.

4. Look Beyond the Headline Price

The 'cheapest' tariff isn't always just about the lowest unit rates. Consider the following:

• Standing Charge: A low unit rate with a high standing charge might not be the cheapest if you use very little energy.
• Customer Service: A super cheap tariff might not be worth the headache if the supplier has a reputation for poor customer service. Check reviews on Trustpilot or Ofgem's customer service ratings.
• Payment Method: Direct Debit is almost always cheaper than prepayment meters or paying on receipt of a bill.
• Green Credentials: If environmental impact is important to you, consider a supplier offering 100% renewable electricity, even if it's slightly more expensive.

5. Weigh Up Fixed vs. Variable Tariffs

This is a crucial decision when trying to find the cheapest energy tariff.

• Fixed Tariff: Offers price certainty. If you believe energy prices are likely to rise, fixing can protect you. However, you won't benefit if prices fall (unless your supplier has a 'no exit fee' clause or a pledge to reduce prices).
• Variable Tariff: Offers flexibility. If you expect prices to fall, a variable tariff allows you to benefit immediately. However, your bills will increase if prices rise.

In uncertain markets, a fixed tariff can offer peace of mind, assuming the fixed rate is competitive with or below the current price cap.

Making the Switch

Once you've found the cheapest energy tariff that meets your needs, switching is usually straightforward:

1. Select your chosen tariff: Follow the steps on the comparison site or the supplier's website.
2. Provide necessary details: Your address, meter readings (though smart meters can often provide these automatically), and bank details for Direct Debit.
3. The new supplier handles the switch: They will contact your old supplier and arrange the transfer. This usually takes around 5 working days, though it can be up to 15 working days. You have a 14-day cooling-off period if you change your mind.
4. No interruption to supply: Your energy supply will not be interrupted during the switch.

Tips for Ongoing Savings and Finding the Cheapest Tariffs

• Set a reminder: Note down when your fixed-term contract is due to end. Aim to compare tariffs a few weeks before it expires to avoid automatically rolling onto an expensive SVT.
• Review regularly: Even on a variable tariff, it's good practice to check comparisons every 6-12 months to ensure you're still on a competitive deal.
• Reduce your usage: The cheapest energy tariff is still one you don't use. Focus on energy efficiency – turn off lights, insulate your home, use energy-efficient appliances, and adjust your thermostat.
• Consider a smart meter: Smart meters provide real-time usage data, helping you understand where your energy goes and identify areas for reduction. They also ensure accurate billing.
• Direct Debit is key: Almost all the cheapest energy tariffs require payment by Direct Debit. Ensure your payments are set correctly and reviewed periodically.
• Prepayment meters: If you're on a prepayment meter, tariffs are generally more expensive than Direct Debit tariffs. If you're able, consider switching to a credit meter (though this depends on your credit rating and supplier policies).

The Role of Competition in Finding the Cheapest Energy Tariff

Post-energy crisis, many smaller suppliers exited the market, and competition significantly reduced. This made finding significantly cheaper fixed deals much harder, as most suppliers offered tariffs very close to the price cap. However, as the market stabilises, competition is slowly returning, leading to more varied and potentially cheaper fixed tariff options appearing again.

It's always wise to check the latest market conditions and news when you are looking to switch, as this will influence the types of deals available.

What if I'm Struggling to Pay?

If you're having difficulty affording your energy bills, even after finding the cheapest energy tariff, it's crucial to seek help:

• Contact your supplier: They have a duty to help customers in financial hardship and can offer payment plans or access to hardship funds.
• Check for grants: Government schemes (like the Winter Fuel Payment or Cold Weather Payment) and energy supplier hardship funds can provide support.
• Get free debt advice: Organisations like Citizens Advice, National Debtline, or StepChange Debt Charity offer free, impartial advice.

Finding the cheapest energy tariff in the UK is an ongoing process, not a one-time task. By staying informed, regularly comparing, and understanding your energy usage, you can keep your bills as low as possible. Don't be afraid to switch; it's a simple process that can lead to significant annual savings.

Takeaway

Finding the cheapest energy tariff in the UK is achieved by regularly comparing deals on Ofgem-accredited sites, understanding the difference between fixed and variable tariffs, and knowing your annual energy usage. Always factor in standing charges, exit fees, and customer service reviews when making your decision. Switching is quick, free, and can save you hundreds of pounds each year.
