How do I compare energy deals on EnergyPlus?

Go to https://www.energyplus.co.uk/compare and enter your postcode and a few details about your home or business. We’ll show available tariffs and help you compare prices, contract length, and key features so you can choose the best value deal.

What information do I need to get an accurate comparison?

For the most accurate results, have your postcode and either your annual kWh usage (electricity and/or gas) or your current bill to hand. If you don’t know your usage, you can still compare by providing a best estimate and updating it later.

Can I compare both electricity and gas?

Yes. You can compare electricity-only, gas-only, or dual fuel options. Comparing both together can make it easier to see your total estimated costs in one place.

How long does it take to switch energy supplier?

In most cases, switching is straightforward and typically completes within a few working days, depending on your meter type and supplier processes. Your energy supply won’t be interrupted during the switch.

Will my energy supply be interrupted if I switch?

No. Switching supplier doesn’t require any physical changes to your supply, so your gas and electricity stay on throughout the process.

Are there any exit fees if I change tariff or supplier?

Some fixed-term tariffs may include exit fees if you leave before the end of the contract. Any applicable fees should be shown in your tariff details before you proceed, so you can compare total value with confidence.

Is comparing and switching through EnergyPlus free?

You can use the comparison journey on https://www.energyplus.co.uk/compare without paying a fee. Any costs you pay are those charged by the supplier under the tariff you choose.

What’s the difference between fixed and variable energy tariffs?

A fixed tariff typically locks in your unit rates for a set term, helping protect you from price changes. A variable tariff can change over time, which may go up or down. Comparing both helps you choose what best suits your budget and risk preference.

Can I compare business energy prices as well as home energy?

Yes. If you’re comparing for a business, you may be asked for additional details such as your business address and energy usage so you can receive a more accurate quote and suitable contract options.

How do I know which deal is best for me?

Compare the estimated annual cost, unit rate, standing charge, contract length, and any fees or benefits. If you’re unsure, start with your current usage and choose a tariff that matches how you prefer to budget—fixed for predictability or variable for flexibility.

If you have your latest bill handy with your annual kWh usage, your results will be more accurate — but it's not required to get a comparison.

Before you compare

This comparison is for UK home energy only — not business energy.
We compare tariffs on total cost: unit rate plus standing charge, not unit rate alone.

Comparing electricity only, gas only or dual fuel?

We compare electricity-only, gas-only and dual fuel tariffs where available. The cheapest energy deal for your home depends on your region, meter type, payment method and usage — which is why a postcode-based comparison beats any national headline rate.

Why compare energy tariffs rather than staying with your current supplier?

Most UK households overpay on energy because they don't compare when their fix ends. The cheapest energy deal for your home is rarely the one you're automatically rolled onto. Here's what a proper comparison gives you.

Total cost — not just unit rate

Comparing unit rates and standing charges together reveals the actual annual cost — a lower unit rate doesn't always mean a cheaper bill.

Fixed vs variable — choose what suits you

A fixed tariff locks in your rate for a set period, giving predictable bills. A variable tariff can be cheaper short-term but may change. Comparing shows which type is currently better value.

Avoid your rollover rate

When a fixed deal ends, you typically move to your supplier's standard variable rate — which is rarely the cheapest option. Comparing before your end date puts you in control.

Right tariff for your meter

Economy 7, smart meters and prepayment meters have different tariff availability. A comparison matched to your meter type shows deals you can actually get — not ones you can't.

Understand why your bill has changed

If your direct debit has gone up, comparing tariffs shows whether it's your rate, your usage, or both — and whether switching to a better deal would reduce costs.

Whole-of-market view in one place

Going direct to a single supplier only shows you their deals. A whole-of-market comparison shows options from across the UK energy market so you're not missing a cheaper alternative.

How to compare and switch energy tariffs in the UK

Comparing energy prices is straightforward. The goal is to estimate what you'd pay on available tariffs — unit rate multiplied by your usage, plus daily standing charge — and find the deal that gives the lowest annual cost for your home.

Enter your postcode. This confirms your distribution region, which directly affects the unit rates and standing charges available to you — energy prices vary across the UK.
Tell us your meter type and payment method. Economy 7, smart meter, prepayment and standard credit meters each have different tariff availability. Direct debit tariffs are typically cheaper than pay-on-receipt.
We compare tariffs on annual cost. Rather than headline unit rates, we estimate full annual cost including standing charges, so comparisons are fair and like-for-like.
Choose a deal and switch. If you find a cheaper tariff and want to move, switching is an administrative process — your gas and electricity supply is never interrupted.

Does comparing commit me to switching?

No. Comparing energy tariffs just shows you the options — you only switch if you choose to proceed. If you want more time to decide after seeing your results, there's no pressure or deadline.

What do I need to compare energy tariffs?

You can get an energy comparison with just your postcode, but having a few extra details from your bill makes the results more accurate — particularly if your household uses significantly more or less than average.

Useful but not essential

Your annual energy usage in kWh (on your bill or online account)
Your current tariff name and end date if you're on a fix
Your payment method: monthly direct debit, pay on receipt, or prepayment
Whether you're on Economy 7 or have a multi-rate meter

What you must have

Your postcode — energy prices vary by region across the UK
Contact details so we can send or discuss your comparison results
Confirmation this is for a UK home, not a business

Always compare standing charge alongside unit rate

Two tariffs with almost identical unit rates can have very different annual costs if their standing charges differ. Low-usage households are particularly affected — a lower unit rate rarely compensates for a significantly higher standing charge if you don't use much energy.

UK energy tariff types explained — fixed, variable, dual fuel and more

Understanding what type of tariff you're on — and what the alternatives are — is the first step to finding the cheapest energy deal for your home. Use the table below to identify which tariff type suits your household.

Tariff type	How it works	Best for	Watch-outs
Fixed	Your unit rate and standing charge are locked for a set period — typically 12 or 24 months. Your bill only varies with usage, not rate changes.	Households wanting predictable monthly bills and protection against rate rises.	Usually includes exit fees (up to £50 per fuel). Check the end date — you may be rolled onto a worse rate automatically.
Variable	Rates can go up or down over time, typically following the Ofgem price cap. No fixed end date and usually no exit fees.	Households wanting flexibility to switch freely without paying exit fees.	Less budget certainty. Your monthly direct debit can increase if the price cap rises.
Dual fuel	Gas and electricity supplied under a single account from one supplier. One bill, one direct debit.	Households wanting simplicity — one supplier for both fuels.	Not always cheaper. Sometimes using two specialist suppliers — one for gas, one for electricity — gives a lower combined cost.
Economy 7 / multi-rate	Two electricity unit rates — a higher daytime rate and a cheaper overnight rate (usually 7 hours off-peak).	Homes with storage heaters, immersion water heaters, or EV charging that runs overnight.	The daytime rate is higher than a single-rate tariff. Only works out cheaper if a large proportion of your usage is off-peak.
Prepayment	Pay in advance via a key, card or smart prepayment meter. You top up as you go rather than paying monthly.	Households who prefer tight control of spending or are required to use a prepayment meter.	Tariff choice can be narrower. Smart prepayment meters can give access to a wider range than traditional key/card meters.

Not sure which type you're currently on? Your energy bill or online account will show the tariff name. If you're still unsure, enter your postcode in the comparison form and we'll identify the most relevant options when we contact you.

Common mistakes when comparing energy prices — and how to avoid them

Comparing unit rates without standing charge

The cheapest unit rate doesn't always mean the cheapest bill. A tariff with a low unit rate but a high standing charge can cost more annually than one with a slightly higher unit rate. Always compare total estimated annual cost.

Missing your tariff end date

If you're on a fixed deal, leaving early can trigger exit fees — typically up to £50 per fuel. Switching one to two months before your end date is usually the sweet spot: no exit fee, and you avoid rolling onto a worse rate.

Not comparing like-for-like payment methods

A monthly direct debit tariff and a pay-on-receipt tariff can have different unit rates even with the same supplier. Always compare tariffs using the same payment method or you risk an inaccurate result.

Ignoring your meter type

Economy 7 and prepayment meters have a different set of available tariffs to standard credit meters. Comparing without confirming your meter type can show deals you're not actually eligible for in your region.

Frequently asked questions about comparing energy tariffs in the UK

What is the cheapest energy tariff in the UK right now?

The cheapest energy tariff depends on your postcode, meter type and payment method — there is no single national cheapest deal. Regional unit rates and standing charges vary significantly across England, Scotland and Wales. Use the comparison form with your postcode to see which tariffs are cheapest for your specific home and usage level.

Will switching energy supplier cut off my gas or electricity?

No — switching energy supplier in the UK never interrupts your supply. Gas and electricity continue through the same pipes and wires regardless of which company is billing you. The switch is an administrative change that typically completes within a few working days, and you'll receive a final bill from your old supplier based on a meter reading taken at the switch date.

How do I compare gas and electricity prices by postcode?

Enter your postcode in the comparison form above. Energy prices in the UK are set by distribution region — the same tariff from the same supplier can have different unit rates and standing charges depending on where you live. A postcode-based comparison is the only accurate way to see what you'd actually pay.

What's the difference between unit rate and standing charge?

The unit rate (measured in pence per kWh) is what you pay for each unit of gas or electricity you use. The standing charge (measured in pence per day) is a fixed daily cost covering the maintenance of your connection — you pay it regardless of how much energy you use. Both together determine your total bill, which is why comparing unit rate alone gives an incomplete picture.

Can I compare energy tariffs if I'm renting?

Yes, in most cases. If you're a tenant and you pay your own energy bills directly, you can compare and switch supplier just like a homeowner. If your energy costs are included in your rent or managed by your landlord, you may not be able to switch — but it's worth submitting the form and we'll advise based on your specific situation.

Is it worth switching energy tariff in 2026?

For many households, yes — particularly if your fixed tariff has recently ended or is ending soon. When a fixed deal expires, most suppliers roll you onto their standard variable rate, which is often not the cheapest option on the market. Fixed deals in 2026 can offer unit rates below the Ofgem price cap level. Comparing now shows whether you could reduce your annual bill by switching.
