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

The best tariffs for new customers change frequently and depend on your postcode, payment method, and whether you want a fixed or variable plan. Use the latest tariff list on this page to compare current new-customer deals and then request a quote to see your estimated annual cost.

Are these tariffs available to existing customers or only people switching supplier?

Most ‘new customer’ tariffs are aimed at people switching from another supplier or joining a supplier for the first time at a property. Availability can vary by supplier and region, so check the tariff eligibility details and confirm during sign-up.

Is it better to choose a fixed or variable energy tariff right now?

A fixed tariff can offer price certainty for the fixed term, while a variable tariff can move up or down with the market and price cap changes. Compare the unit rates, standing charges, exit fees, and contract length on this page to choose the option that best fits your risk preference and plans to stay in your home.

How do I compare energy tariffs accurately (unit rates and standing charges)?

Compare both the unit rate (p/kWh) and the standing charge (p/day) for electricity and gas. The cheapest tariff for you depends on usage, so use your last 12 months of kWh (or a recent bill) and your postcode to estimate annual cost and avoid choosing based on unit rate alone.

Do new customer tariffs have exit fees?

Many fixed deals include exit fees if you leave before the contract ends, while variable tariffs often have no exit fee. Always check the tariff terms shown for each deal before switching so you know the cost of leaving early.

How long does it take to switch energy supplier in the UK?

Switching is usually completed within a few working days for most suppliers, with no interruption to your energy supply. After you apply, you’ll normally receive confirmations and a date for the switch to go through.

Will my energy supply be interrupted when I switch?

No. Your gas and electricity continue to be delivered through the same pipes and wires, so switching supplier does not cause an outage. Only your billing and customer service provider changes.

Can I switch if I’m in debt to my current supplier?

You may still be able to switch, but eligibility depends on the size of the debt, payment method, and whether you have a prepayment meter. If you’re unsure, review your account status and check supplier rules during the application.

What information do I need to get an accurate quote and switch?

You’ll typically need your postcode, current supplier name, payment method, and your typical usage (kWh) or a recent bill. If available, provide your MPAN (electricity) and MPRN (gas) for the most accurate matching.

How can I make sure I’m not overpaying on a new customer tariff?

Compare the total estimated annual cost, not just headline rates. Check standing charges, contract length, exit fees, and any discounts or incentives. If your usage changes seasonally, consider how the tariff performs at your expected yearly consumption before you switch.

What “new customer” energy tariffs mean in the UK

In the UK, many suppliers price some deals specifically for new customers — typically meaning you’re not currently supplied by that company. These tariffs can be available to households switching from another supplier, moving home, or returning to the market after time on a default tariff.

Why deals change week to week

Suppliers adjust pricing based on wholesale costs and risk.
Some tariffs are limited by region, meter type or payment method.
Providers can pause or reopen tariffs depending on demand.

What whole-of-market means at EnergyPlus

We compare across a wide range of UK suppliers where data is available.
You can weigh up cost, contract terms, and flexibility.
We focus on home energy (residential), not business.

If you’re unsure whether you qualify as a new customer for a particular supplier, don’t worry — we’ll flag eligibility as part of the options shown for your postcode.

Why compare tariffs this week (not later)

See what’s actually available

Rather than guessing from headlines, check live availability based on your postcode and meter type. If a deal closes, you’ll still see other options.

Control your risk

Compare contract lengths, exit fees and price structures so you can pick a tariff that matches your appetite for certainty vs flexibility.

Avoid costly roll-overs

If your fixed term is ending, you may be moved to a default tariff. Starting your comparison now helps you switch in time.

Good to know: The cheapest tariff isn’t always the best fit. We encourage you to check unit rates, standing charges, contract length, and any fees — then choose based on your household’s needs.

How switching energy supplier works in the UK

Tell us your postcode and preferences. We identify your region and show eligible tariffs for new customers this week.
Compare like-for-like. Review unit rates, standing charges, tariff type (fixed/variable), contract length, payment method, and fees.
Choose your tariff. If you proceed, your new supplier coordinates the switch — you usually don’t need to contact your current supplier to cancel.
Provide a meter reading (if asked). This helps create an accurate final bill with your old supplier.
Your supply stays on. There’s no interruption to energy supply in normal circumstances; only the billing supplier changes.

What if I’m moving home?

You can still compare. Many people take a meter reading on move-in day, then decide whether to stay with the deemed supplier tariff or switch to a new-customer deal.

Will I pay exit fees?

Some fixed tariffs have exit fees if you leave during the term. We recommend checking terms before choosing — especially if you might move soon.

Fixed vs variable tariffs: what new customers should compare

When you compare energy tariffs for new customers this week, you’ll usually see a mix of fixed and variable deals. The right choice depends on how much price certainty you want and how likely you are to change tariff again within the next year.

Feature	Fixed tariff	Variable tariff
Price stability	Unit rate and standing charge are set for the contract term (subject to terms).	Rates can change (often with notice), so bills may rise or fall over time.
Exit fees	Common, especially on longer fixes.	Less common; many variable tariffs have no exit fees.
Best for	Households wanting predictable payments and fewer surprises.	People who want flexibility and may switch again if prices improve.
What to check	Term length, fees, what happens at the end of the fix, payment method.	How and when prices can change, any discounts, payment method.

Standing charges matter: Two tariffs can look similar but differ in standing charge vs unit rate. If you use relatively little energy, standing charges can have a bigger impact on your overall cost.

What you’ll need to compare accurately

1) Postcode

Determines your electricity distribution region and which tariffs are available to new customers this week.

2) Meter type

Smart, credit, or prepayment can affect eligibility and pricing. Economy 7/10 matters for many electric heating homes.

3) Usage (if you have it)

Annual kWh from a recent bill gives the best comparison. If not, we can start with an estimate and refine later.

Common tariff terms to recognise

Unit rate — the price per kWh you use.
Standing charge — a daily fixed cost for having a supply.
Direct Debit — many tariffs are priced for monthly Direct Debit; other payment methods may differ.
Exit fee — a charge for leaving a tariff early (often on fixed deals).
Deemed contract — the default tariff you’re put on when you move in until you choose a new one.

Regional considerations across the UK

Energy pricing can vary by region because electricity distribution costs differ around the UK. That’s why the same supplier can show slightly different rates in different postcodes.

England, Scotland & Wales

Tariffs are often available across multiple regions, but unit rates and standing charges may vary. We use your postcode to show the correct regional pricing.

Northern Ireland

The market operates differently from Great Britain. Availability and switching processes can vary, so your postcode is essential to show what’s possible this week.

Economy 7 / multi-rate meters: If you use electric heating or charge devices overnight, comparing multi-rate tariffs can make a significant difference. Include your meter type where possible.

Common mistakes when choosing a new-customer energy tariff

Only comparing monthly payments

Monthly figures can be based on estimates. Always look at unit rates and standing charges and sense-check against your actual usage.

Ignoring exit fees

A slightly cheaper fixed deal may not be worth it if you might move or want the freedom to switch again soon.

Choosing the wrong meter tariff

Economy 7 and prepayment tariffs are structured differently. Make sure your tariff matches your meter and usage pattern.

FAQs: energy tariffs for new customers this week

Can I switch energy supplier if I’m renting?

Often, yes — as long as you’re responsible for paying the energy bills and your tenancy agreement doesn’t restrict supplier choice. If you’re unsure, check with your landlord or letting agent.

How long does switching take?

Timeframes can vary by supplier and circumstances, but switching is typically completed within a few weeks. Your energy supply stays on throughout; only the billing supplier changes.

Do I need a smart meter to access the best tariffs?

Not necessarily. Many tariffs are available to standard credit meters as well. Some deals may be restricted by meter type, so it’s best to compare using your actual setup.

Is it better to fix or stay on a variable tariff this week?

It depends on your budget and preference for stability. Fixed tariffs offer predictability, while variable tariffs offer flexibility. Compare what’s available for your postcode and review contract terms before deciding.

Will switching affect my credit score?

Some suppliers may run checks depending on tariff type and payment method. If you’re concerned, consider tariffs suited to your circumstances and review eligibility as part of your options.

What if I have a prepayment meter?

You can still compare. Availability varies by area and supplier, so entering your postcode helps us show what’s open to new customers this week for your meter type.
