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

The best tariffs for new customers are usually the lowest-cost options available for your postcode and usage—often a competitive fixed tariff or a discounted variable tariff. Prices change frequently, so compare live deals for your area and check the total estimated annual cost (not just the unit rate).

How do I find the cheapest tariff for my postcode?

To find the cheapest tariff, compare offers using your postcode, payment method (Direct Debit/credit/prepay), and typical annual usage (kWh). The cheapest deal is the one with the lowest estimated annual bill after standing charges and unit rates are combined.

Are fixed tariffs better than variable tariffs for new customers?

Fixed tariffs can provide price certainty for a set term, while variable tariffs can move up or down with the market and price cap changes. For many new customers, a competitively priced fixed deal can help protect against short-term price rises, but it’s worth comparing total cost and any exit fees.

Do new-customer energy deals include exit fees?

Some fixed tariffs include exit fees if you leave before the end of the term, while many variable tariffs do not. Always check the tariff’s exit fee and contract length before switching—especially if you may want to move again soon.

Can I switch energy supplier if I’m in debt?

In many cases, yes—particularly if you pay by credit meter and your debt is below the supplier’s threshold. If you’re on prepayment, options can be more limited, but switching may still be possible depending on your circumstances and the supplier’s rules.

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

A switch typically completes within a few working days, and you should not experience any interruption to your gas or electricity supply. Your new supplier will handle the process, including the start date and meter reading arrangements.

Will switching affect my credit score?

Switching supplier usually doesn’t impact your credit score, but some suppliers may run a credit check for monthly Direct Debit tariffs. If you’re concerned, look for tariffs with flexible payment options or suppliers that offer alternatives where available.

What details do I need to switch energy tariffs?

You typically need your postcode and address, the name of your current supplier, your payment method, and your estimated annual usage (or a recent bill). Having your meter type and MPAN/MPRN can help, but is not always required to start comparing.

Are green energy tariffs cheaper for new customers?

Green tariffs can be competitively priced, but costs vary by supplier and tariff type. Compare green and standard options using the same usage assumptions and check what the supplier means by “renewable” (e.g., REGO-backed renewable electricity).

Compare tariffs for my postcode How we find this week’s deals

New-customer tariffs and availability vary by region, meter type and payment method. Estimated costs shown during comparison are based on your inputs and current price information available at the time of search.

Compare new-customer energy tariffs available in your area

“Best” depends on your postcode, meter type and how you pay. Instead of guessing, compare live tariffs based on your details—then decide whether a fixed deal, a low standing charge, or a competitive unit rate is the better fit for your household.

EnergyPlus is a whole-of-market home energy comparison service. That means we aim to show a broad range of suppliers and tariff types, including deals designed to attract new customers, where available.

To see accurate prices, we’ll ask for:

Your postcode (tariffs vary by region)
Whether you want gas, electricity or dual fuel
Your contact details so we can send your results and help you switch

Tip: If you know your current unit rates and standing charges, keep them handy. It makes it easier to confirm whether a “new customer” deal is genuinely better than staying put.

Why new-customer tariffs can be worth checking each week

Suppliers change prices and eligibility frequently. This is why “this week” matters: even small differences in unit rate or standing charge can materially change your estimated annual cost, especially if you use more energy during winter.

Access promotional pricing

Some tariffs are targeted at new customers or switchers. We help you spot where the pricing is genuinely competitive for your postcode and meter setup.

Compare the full cost, not just the headline

A low unit rate can be offset by a high standing charge (and vice versa). EnergyPlus focuses on the combined effect for your household.

Switch without disruption

Switching supplier shouldn’t mean losing power or gas. In most cases, the change is administrative and your supply stays on throughout.

Fixed vs variable clarity

If you want predictable bills, fixed deals may suit you. If you want flexibility, variable tariffs might be better. We’ll show both where available.

Options for different meters

Smart meter, credit meter or prepayment: tariff availability can differ. Comparing by postcode helps narrow down what you can actually switch to.

Whole-of-market view

Don’t limit yourself to one supplier’s website. We bring together a broad range of tariffs so you can make a confident, informed choice.

How EnergyPlus finds the best new-customer energy tariffs this week

We base comparisons on your location and your current energy setup. “This week” reflects the latest tariff and pricing information available to us at the time you run your search. Because suppliers can update rates quickly, two homes— even on the same street—can see different results depending on meter type and payment method.

What “best tariff” usually means in practice

For most households, the best tariff is the one with the lowest expected total cost for your typical usage—while also matching your preferences on contract length, exit fees, and payment method. That’s why we present the underlying rates and key terms, not just a headline figure.

Tariff types explained (so you can choose confidently)

When you compare energy tariffs for new customers, it helps to know what you’re actually comparing. Below is a straightforward breakdown of the most common options for UK households.

Tariff type	What it is	Who it suits	Watch-outs
Fixed	Unit rates are fixed for a set term (e.g., 12 months).	Homes that want stable pricing and predictable budgeting.	May include exit fees; if market prices fall you might pay more than newer deals.
Variable	Rates can change over time (supplier pricing and/or market movements).	Homes that want flexibility and fewer long-term commitments.	Costs can rise; check how and when rates can change.
Dual fuel	Gas and electricity with the same supplier.	Homes that prefer one bill and streamlined support.	Not always cheaper—compare separate suppliers too if relevant.
Electricity-only	For properties without mains gas or with electric heating.	Flats, all-electric homes, or heat pump households.	Ensure the tariff matches your meter (single rate vs multi-rate).

If you’re unsure, start with a comparison and shortlist tariffs with the best overall cost. Then check the key terms like exit fees, contract length, and whether the deal is available to new customers in your region.

New-customer switching checklist (avoid common mistakes)

Before you switch

Check whether you’re on a fixed tariff and if exit fees apply.
Confirm your meter type (smart/credit/prepayment; single vs multi-rate).
Consider whether you prefer monthly Direct Debit or another payment method.
Have your latest bill ready so you can compare unit rates and standing charges.

When reviewing deals

Compare the total estimated cost, not just the headline discount.
Look at standing charges—especially if your usage is low.
Check contract length and whether you can switch again without penalty.
Verify the tariff is available to new customers in your postcode area.

Common pitfall: chasing a low unit rate alone

Some tariffs pair a low unit rate with a higher standing charge. If you’re out at work all day or live in a smaller property, that can reduce the benefit. Comparing by estimated annual cost helps keep the decision grounded.

Why your postcode matters for “best” energy tariffs

Energy prices can vary across Great Britain due to regional electricity distribution costs and how suppliers structure tariffs. That’s why a deal that looks great nationally might not be the cheapest for your area.

Distribution regions

Your electricity region affects parts of the standing charge and unit rate structure shown in comparisons.

Meter configuration

Multi-rate and smart meters can unlock (or restrict) certain tariffs. We tailor results to what’s plausible for your home.

Supplier availability

Not every supplier markets every tariff in every area. Postcode-based filtering avoids wasting time on unavailable deals.

FAQs: best energy tariffs for new customers

Are there special deals just for new customers?

Sometimes, yes. Some suppliers price certain tariffs to attract switchers, while others keep pricing consistent for new and existing customers. The best approach is to compare what’s available for your postcode this week.

Will switching interrupt my gas or electricity supply?

In most home switches, there’s no interruption. Your physical supply stays on; the change happens behind the scenes between suppliers.

How often do tariffs change?

It varies. Some tariffs remain stable for weeks; others change more frequently. That’s why checking “this week” can uncover new pricing or refreshed offers.

What details do I need to compare accurately?

Postcode is the key starting point. If you have your latest bill, you can also check your current unit rates and standing charges to make a like-for-like comparison.

Is a fixed tariff always best for new customers?

Not always. Fixed tariffs can offer predictability, but variable tariffs can offer flexibility. The “best” choice depends on your risk preference, likely length of stay, and whether exit fees apply.

Can I compare electricity-only tariffs?

Yes. If your home doesn’t use mains gas, you can compare electricity-only deals. We’ll focus on tariffs that match your meter type and region.
