What are the best energy tariffs for new customers in the UK this month?

The best energy tariffs for new customers this month are typically the plans with the lowest estimated annual cost for your postcode and usage. Compare fixed and variable options, check unit rates (p/kWh) and standing charges (p/day), and confirm any exit fees before switching. Use EnergyPlus to compare current UK tariffs and see which deals you can switch to today.

Can I switch energy supplier as a new customer if I’m in a contract?

Yes, but you may need to pay an exit fee if you’re on a fixed-term tariff. Many suppliers waive exit fees in the last 49 days of your contract. Check your current tariff terms, then compare new-customer tariffs to see if switching now saves you money overall.

How long does it take to switch to a new energy tariff?

Most UK switches complete within around 5 working days under the faster switching process, although timings can vary. You’ll keep your supply throughout—only billing changes.

What information do I need to compare energy tariffs and switch?

You’ll usually need your postcode, whether you want gas, electricity or both, and an estimate of your usage (kWh) or monthly spend. If you have it, your current unit rate and standing charge help improve accuracy, but you can still compare without them.

Is it cheaper to choose a fixed or variable tariff as a new customer?

It depends on market prices and your risk preference. Fixed tariffs can offer price certainty for a set term (often with an exit fee). Variable tariffs can change with the market and may be more flexible. Compare total estimated annual costs and check the tariff’s rates, standing charges and contract terms before choosing.

Will switching affect my credit score?

Some suppliers may run a credit check when you apply, which can leave a record on your file. This is usually minor, but if you’re concerned, review supplier requirements and consider tariffs that offer alternative options such as pay-as-you-go or no-deposit products where available.

Are there any fees for switching energy supplier?

Energy switching is usually free, but your current supplier may charge an exit fee if you leave a fixed tariff early. Always confirm exit fees and compare them against the savings from a new-customer deal.

How do I make sure I’m comparing tariffs accurately?

For an accurate comparison, use your actual annual consumption (kWh) from recent bills if possible, and compare both unit rates and standing charges. Also check payment method (direct debit vs prepayment), tariff length, exit fees, and any discounts or bundle terms.

Already with a supplier? You can still switch—new customer tariffs are typically aimed at customers joining from another supplier (and sometimes from another tariff with the same supplier, depending on their rules).

What does “new customer energy tariff” mean in the UK?

A new customer tariff is a deal offered to people who are joining a supplier (or moving onto a promotional tariff) rather than staying on a default or standard variable tariff. Some suppliers also restrict certain online tariffs to new joiners only. Availability changes throughout the month, so checking current options is the best way to see what you can actually switch to today.

Important: We don’t publish “one-size-fits-all” cheapest tariffs because UK pricing depends on your region, meter type and consumption. Use the form above for tailored quotes.

Understanding tariffs: fixed vs variable, and what to check

If you’re comparing energy tariffs for new customers, it helps to understand what actually drives your bill. The two biggest line items are the unit rate (what you pay per kWh) and the standing charge (a daily cost regardless of usage). Contract terms and fees can matter too.

What you’re comparing	Why it matters	What to look for
Unit rate (p/kWh)	Your main cost when you use energy.	Lower isn’t always best if the standing charge is high—compare the total estimated cost.
Standing charge (p/day)	Paid every day, even if you use very little.	If you’re a low user, this can dominate your bill—check carefully.
Fixed tariff	Rates are set for the contract term.	Contract length, exit fees, and what happens at end of term.
Variable tariff	Rates can change over time.	Flexibility (often fewer fees) vs price certainty.
Exit fees	A charge for leaving a fixed tariff early.	If you might move home soon, a lower/no exit fee could be preferable.

Why “this month” matters

Suppliers can launch or withdraw tariffs, and rates can change. Comparing this month’s new customer energy tariffs gives you the most up-to-date view of what you can actually switch to in your postcode area.

Costs, savings and what affects your quote

There isn’t a single “best” tariff for everyone in the UK. Your likely cost depends on your region, usage, meter type, and how you pay. That’s why a personalised quote is more reliable than a headline rate.

Factors that change the price

Postcode region: network costs vary around the UK
Electricity meter type: standard vs Economy 7/other time-of-use
Payment method: some tariffs are priced for monthly Direct Debit
Usage level: high standing charges can hit low users harder
Tariff length: longer fixes can price in more certainty

How to compare properly

Compare the estimated annual cost for your usage
Check standing charge and unit rate together
Look for exit fees and contract end dates
Confirm any eligibility rules (new customers, online-only, etc.)
Choose a tariff that fits your risk preference (fixed vs variable)

If you want to compare quickly, start with your postcode and payment method in the quote form. You can refine usage details later if needed.

Eligibility: who can get new customer energy deals?

Most UK households can switch, but tariff eligibility can vary. Here are the most common considerations when you’re looking for new customer energy tariffs this month:

Tenants

If you pay the energy bills, you can usually choose your supplier. If bills are included in rent, you may not be able to switch.

Prepayment meters

Some tariffs are limited for prepayment. We’ll show what’s available for your meter type and postcode.

Debt and arrears

If you have energy debt, switching may still be possible depending on circumstances. It’s best to check options and speak to your supplier.

If you’re unsure, submit the form and we’ll show tariffs that match your details. You’ll see the key terms before committing.

Common mistakes when choosing a tariff (and how to avoid them)

Comparing on unit rate only

A low unit rate can be offset by a higher standing charge. Use the estimated annual cost to compare like-for-like.

Not checking exit fees

If you may move home or want flexibility, choose a tariff with suitable terms and fees.

Guessing usage wildly

If your estimate is far off, your quote won’t reflect your true cost. Use your last 12 months’ kWh if possible.

Ignoring meter type

Economy 7/time-of-use pricing can change what “best value” means. Make sure quotes match your meter setup.

FAQs: new customer energy tariffs in the UK

Can I get a new customer tariff if I’m already with that supplier?

It depends on the supplier and tariff rules. Some deals are strictly for brand-new joiners; others are available to existing customers switching tariff. Your results will reflect what’s currently available based on your details.

How long does it take to switch energy supplier?

Timescales can vary by supplier and circumstances, but switching is typically completed within a few weeks. Your new supplier will confirm the expected switch date after you apply.

Will I need a smart meter for the best deals?

Not always. Some tariffs work with standard meters, while certain time-of-use tariffs may require a compatible meter. Your quote options depend on what’s available for your meter type and area.

Do I pay anything to use EnergyPlus?

You can compare tariffs and view quotes without paying a fee to EnergyPlus. If you choose to switch, you’ll pay the supplier for your energy under the tariff you select.

What information do I need to compare?

Start with your postcode and how you prefer to pay. For the most accurate comparison, use your annual kWh usage for gas and electricity from a recent bill (or a realistic estimate if you don’t have it).

Is this for business energy?

No—this page is for UK home energy customers. If you need business energy, you’ll need a separate business comparison journey.
