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

The best tariffs for new customers are usually the cheapest fixed or competitive variable deals available for your postcode, payment method and usage. To see current options, compare quotes on EnergyPlus and sort by estimated annual cost, then check exit fees, tariff length and any perks before switching.

How do I find the cheapest energy tariff for my home?

Use your postcode and typical annual usage (kWh) to compare like-for-like prices. Review the unit rate (p/kWh) and standing charge (p/day), then compare the estimated annual cost. You can start your comparison at https://www.energyplus.co.uk/Suppliers/best-uk-energy-tariffs-for-new-customers-this-week.

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

Fixed tariffs can offer price certainty for a set term, while variable tariffs can change with market conditions. If you prefer predictable bills, a fixed deal may suit you; if you want flexibility and may switch again soon, a variable tariff may be better. Always check exit fees and the contract end date before switching.

Will switching energy supplier interrupt my gas or electricity supply?

No. Switching supplier should not interrupt your gas or electricity supply because the same physical networks deliver your energy. Your new supplier takes over billing and customer service on the agreed switch date.

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

Many UK switches complete in around 5 working days, though timings can vary if there are meter or account issues. You’ll receive confirmation of your switch date and should provide a meter reading around the time of the switch for accurate final billing.

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

Typically you’ll need your address and postcode, your current supplier, whether you pay by Direct Debit or prepayment, and your estimated annual usage (or a recent bill). If you have a smart meter, your usage data can help improve quote accuracy.

Are there exit fees when switching energy tariffs?

Some fixed tariffs include exit fees if you leave before the end of the term. Variable tariffs are often fee-free, but not always. Check the tariff’s exit fee and any cooling-off period before you switch to avoid unexpected charges.

How can I make sure I’m comparing tariffs fairly?

Compare the same tariff type and payment method, and use your own usage figures where possible. Look at unit rates and standing charges, then confirm the estimated annual cost, contract length, exit fees and customer service factors.

Can I switch energy supplier if I’m in credit or in debt with my current supplier?

If you’re in credit, your old supplier should refund the balance after your final bill (or transfer it, depending on the process). If you’re in debt, you may still be able to switch in some circumstances, but you’ll usually need to repay what you owe—especially for standard credit meters.

Do I need to contact my current supplier to switch?

Usually no. When you choose a new tariff, your new supplier will handle the switching process for you. You should still check your current tariff’s end date and exit fees, and keep an eye out for any final bill from your old supplier.

What does “new customer” mean for energy tariffs?

In the UK, some suppliers price certain tariffs for customers who are switching in (new to that supplier). Others make the same deals available to both existing and new customers. When we talk about the best UK energy tariffs for new customers this week, we mean tariffs that are currently open to switchers — subject to eligibility, meter type and your location.

If you’re already with a supplier, you can still switch — even if you’ve recently changed tariff — but check your current plan for exit fees and whether you’re within any fixed-term period.

Why compare tariffs with EnergyPlus?

Whole-of-market results

Compare across UK suppliers rather than being limited to a shortlist. Availability can vary by region, meter type and payment method.

Designed for real decisions

We highlight what matters this week: estimated annual cost, standing charges, unit rates, tariff length and exit fees — so you can compare like-for-like.

Quick, guided switching

Tell us the basics and we’ll match you with available deals for your home. Switching is usually handled by the new supplier with minimal disruption.

Good to know: For most household switches, your energy supply stays on. You’re changing who bills you and on what tariff — not physically changing the pipes or wires.

How switching energy supplier works (step-by-step)

Share your postcode and preferences. We use this to show tariffs available to new customers in your area.
Compare key features. Look at total estimated annual cost, tariff type, contract length, exit fees, and payment method.
Choose a tariff that fits. If you want price certainty, a fixed deal may suit. If you want flexibility, a variable or tracker might be better (depending on risk).
The new supplier manages the switch. They’ll coordinate the process and let you know the date. Your supply usually continues as normal.
Provide meter readings on switch day. This ensures your final bill with the old supplier and first bill with the new supplier are accurate.

What you’ll typically need to hand

Postcode and address details (to match your network region and available suppliers).

Usage estimate (kWh) or recent bills (helps produce more accurate annual cost estimates).

Meter type (credit meter, smart meter, or prepayment) — can affect tariff eligibility.

Current tariff end date and any exit fees (so you can judge if switching now is worthwhile).

If you’re on a standard variable tariff (SVT), there are usually no exit fees. If you’re on a fixed tariff, check before switching.

Tariff types explained: fixed vs variable vs tracker

Tariff type	Best for	Watch-outs	What to check this week
Fixed	Households that want predictable unit rates and standing charges for a set period.	May include exit fees; you might miss out if market prices fall.	Contract length, exit fees, and whether rates are meaningfully below comparable options.
Variable (including SVT)	Flexibility — typically easier to leave without penalties.	Rates can change; not always the cheapest for new customers.	Standing charge vs unit rate balance, and any introductory discounts/benefits.
Tracker	Those comfortable with price movement that follows a published benchmark/market reference.	Bills can rise quickly; not ideal if you need certainty.	The tracking mechanism, update frequency, and any caps/limits.

Standing charge vs unit rate

A tariff with a low unit rate can still be expensive if the standing charge is high — especially for low-usage homes. Always compare the estimated annual cost for your usage.

Dual fuel isn’t always cheaper

Some households save by bundling gas and electricity with the same supplier. Others get a lower total cost by splitting. Comparing both options can be worthwhile.

This week’s “best tariff” checklist (before you switch)

1) Is it actually available?

Some deals are limited by postcode region, meter type (smart/prepay) or supplier capacity. Always check live availability for your address.

2) What are the exit fees?

If the tariff has exit fees, it may still be best — but only if the saving outweighs the cost of leaving early.

3) Are the rates competitive for your usage?

Low users often benefit from lower standing charges; high users may value lower unit rates more. The “best” deal differs by household.

4) Is the payment method right?

Monthly Direct Debit can be priced differently from pay-on-receipt. Prepayment customers may have fewer options — but it’s still worth checking.

5) Are there any incentives?

Some suppliers offer credit, rewards or bundled services. Consider them only after confirming the ongoing tariff costs work for you.

6) Can you switch without hassle?

Most switches are straightforward. If you have debt on a prepayment meter or complex metering, options can be more limited — still tell us and we’ll filter accordingly.

Common mistake: choosing a tariff based on unit rate alone. A slightly higher unit rate with a much lower standing charge can be cheaper overall for some homes.

Regional considerations across Great Britain

Why your postcode affects your quote

Energy pricing can differ by distribution region. Standing charges and unit rates may vary even for the same supplier and tariff name. Using your postcode ensures results reflect the deals available to your home.

Smart meters and prepayment

Some tariffs require certain meter types. If you’re on prepayment, there may be fewer new-customer deals — but there can still be savings, especially if you’re able to move to a credit meter.

Northern Ireland has different energy market arrangements from Great Britain. If you’re in Northern Ireland, availability may differ and not all suppliers will be shown.

FAQs: best UK energy tariffs for new customers

How often do the “best” tariffs change?

They can change daily. Suppliers may withdraw tariffs, add new ones, or adjust pricing based on wholesale costs and demand. That’s why checking live availability for your postcode is important.

Is it safe to switch energy supplier?

Switching is a standard process. In most cases your supply continues uninterrupted; the change is mainly administrative (billing and tariff). Your new supplier manages the switch.

Can I switch if I rent my home?

Often yes, as long as you’re responsible for paying the energy bills. If the landlord includes bills or there’s a specific agreement in place, check your tenancy terms first.

What if I’m in credit with my current supplier?

Any credit on your account is usually refunded after your final bill is produced. Timing varies by supplier.

Will my direct debit change when I switch?

Yes — you’ll set up a new direct debit with the new supplier. Your monthly payment may differ from your previous amount depending on tariff rates, usage and the supplier’s payment calculation.

Do you compare green energy tariffs?

Where available, we can show tariffs marketed with renewable electricity or environmental commitments. Availability and definitions vary by supplier, so always review the tariff details before switching.

Need help choosing? Start with your goal: price certainty (fixed), flexibility (variable) or market-linked pricing (tracker). Then compare total estimated annual cost for your usage.
