How do I compare energy deals on EnergyPlus?

To compare energy deals, enter your postcode and a few details about your current usage (or your current tariff if you know it). We’ll show available tariffs so you can compare estimated costs, contract length and key features, then choose the deal that best fits your home.

What information do I need to get an accurate comparison?

For the most accurate results, use your annual kWh usage for electricity and/or gas (from a recent bill). If you don’t have it, you can still compare using household details and typical usage estimates. Having your current supplier and tariff name can also help.

Can I compare both gas and electricity deals?

Yes. You can compare electricity-only, gas-only, or dual fuel deals. Comparing both together can make it easier to review total household costs and decide whether a single supplier is right for you.

How can I tell which tariff is best value for me?

Compare estimated annual cost alongside the unit rate (price per kWh), the standing charge, contract length, exit fees (if any) and whether prices are fixed or variable. The best value tariff is usually the one that matches your usage pattern and risk preference, not just the lowest headline rate.

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

A fixed tariff keeps the unit rate and standing charge the same for the length of the contract (subject to the tariff terms), helping you budget. A variable tariff can change over time, which may go up or down depending on market conditions and the supplier’s pricing.

Will switching affect my energy supply?

No—your gas and electricity supply stays on. In most cases, only the billing and customer service provider changes. Your meter and existing pipes/wires remain the same.

How long does it take to switch energy supplier?

Switching typically takes a few weeks, depending on your current supplier and the type of switch. You’ll be kept informed of key dates, and your new tariff will start once the switch completes.

Are there any fees to switch or compare energy deals?

Comparing deals is free. Some tariffs may include exit fees if you leave before the contract ends—this will be shown when you compare so you can factor it into your decision.

How do I know if I’ll pay exit fees on my current tariff?

Check your latest bill, your online account, or your contract terms for any early exit fee. If you’re within a fixed-term contract, an exit fee may apply unless you’re in a penalty-free switching window near the end of the term.

Can I switch if I’m renting or living in a flat?

Usually yes—if you pay the energy bills, you can typically choose the supplier. If bills are included in your rent or managed by a landlord or building management, you may not be able to switch.

What if I have a prepayment meter?

You may still be able to compare and switch, but available tariffs can be more limited. Use your meter type during the comparison to see which deals are available for prepayment customers.

What should I check before choosing a new energy deal?

Before choosing a tariff, check the unit rate, standing charge, contract length, payment method, any exit fees, and whether it’s fixed or variable. If you have an Economy 7/Economy 10 or smart meter, ensure the tariff supports your setup.

Why compare energy deals?

Even small differences in unit rates and standing charges can add up over the year. Comparing is useful whether you pay by Direct Debit, prepayment meter, or on receipt of bill, and whether you want a fixed tariff for budget certainty or a variable tariff for flexibility (subject to availability).

See the full picture

Compare based on unit rates, standing charges, tariff length, exit fees and payment method—so you’re not judging on headline figures alone.

Match tariffs to your household

A flat might benefit from different tariff structures than a larger family home. We help you look at options that align with your usage and goals.

Avoid rolling onto poor value rates

When a fixed deal ends, some households drift onto a more expensive option. Comparing ahead of time can help you stay in control.

Tip: If you have a recent bill, note your annual kWh usage for gas and electricity. It’s one of the best ways to compare like-for-like.

Start comparison Understand tariffs

Energy tariffs explained (UK homes)

When you compare energy deals, it helps to understand what you’re actually paying for. Most household bills are made up of a standing charge plus a unit rate for each kWh you use.

Item	What it means	Why it matters when comparing
Standing charge	A daily fixed cost for keeping you connected.	High standing charges can reduce savings, especially for low users.
Unit rate (p/kWh)	What you pay per unit of energy you use.	Often the biggest driver of your annual cost if you use lots of energy.
Fixed tariff	Rates are set for a period (e.g., 12 months).	Can help budgeting; may include exit fees.
Variable tariff	Rates can change over time.	More flexibility, but bills can rise if rates increase.
Dual fuel	Gas and electricity with the same supplier.	May be convenient; best value depends on the combined rates.
Payment method	Direct Debit, prepayment, or pay on receipt.	Some deals are available only for certain payment types.

Comparing like-for-like

When reviewing deals, check whether quoted costs are based on your usage. If you don’t know your kWh, using an estimate is a sensible starting point—then refine it when you find your latest bill.

Savings checklist: what to look for when comparing

Costs that matter most

Compare standing charge and unit rate together
Check if prices differ by region (they often do)
Look for exit fees on fixed deals
Confirm any discounts are genuine and not time-limited gimmicks

Practical checks

Confirm your meter type (credit, prepayment, smart)
If you’re moving, note your move-in date and current supplier
Decide whether you value price certainty or flexibility
Keep an eye on customer service and billing preferences

Common comparison mistakes to avoid

Focusing only on monthly estimates and not checking kWh costs
Ignoring standing charges (especially for low usage households)
Assuming dual fuel is always cheaper

Forgetting to check tariff end date and potential exit fees
Not accounting for payment method eligibility
Switching in a rush without reviewing the full tariff terms

FAQs about comparing energy deals

Is it worth comparing if I’m on a standard variable tariff?

Often, yes. Standard variable tariffs can change, and they may not be the best value for every household. Comparing helps you check what alternatives exist right now for your postcode and meter type.

Do I need my bill to compare?

No. If you have your annual kWh usage it improves accuracy, but you can still start with an estimate and refine later.

Will my supply be interrupted if I switch?

Typically, no—switching suppliers doesn’t mean your energy is turned off. Your meter and pipes/wires remain the same; only the billing supplier changes (processes can vary).

Can I compare if I have a prepayment meter?

Yes, in many cases. Availability depends on your meter type and the tariffs offered in your region. Share your details and we’ll check suitable options.

What does “whole-of-market” mean here?

It means we aim to compare across a broad range of suppliers and tariffs available to UK households, rather than limiting results to a small panel. Availability still varies by postcode, meter type and current market conditions.

Is this for business energy?

No—this page is for home energy at domestic UK addresses. If you need business energy, you’ll need a separate business comparison route.
