What is a dual fuel tariff?

A dual fuel tariff means you get both your gas and electricity from the same supplier, usually on one account. It can be simpler to manage and may offer a better overall deal than buying gas and electricity separately—depending on the rates and standing charges.

Is dual fuel cheaper than separate gas and electricity?

Dual fuel can be cheaper, but it isn’t always. The total cost depends on your unit rates (p/kWh), standing charges (p/day), and how much energy you use. Comparing full annual costs (not just discounts) is the best way to see whether dual fuel saves you money.

What should I compare when choosing a dual fuel deal?

Compare: (1) electricity and gas unit rates (p/kWh), (2) both standing charges (p/day), (3) tariff type (fixed vs variable), (4) contract length and exit fees, (5) payment method (Direct Debit vs PAYG), and (6) any discounts or rewards—making sure they don’t hide higher ongoing rates.

What’s the difference between fixed and variable dual fuel tariffs?

Fixed dual fuel tariffs lock in your unit rates and standing charges for a set term, helping you budget. Variable tariffs can go up or down, usually changing with market conditions and price cap updates. Fixed deals may include exit fees if you leave early.

Can I switch dual fuel if I rent my home?

In most cases, yes. If you pay the energy bills, you can usually switch supplier. If bills are included in your rent or the landlord manages the account, you may need their agreement.

Will switching dual fuel affect my supply or require an engineer visit?

Switching should not interrupt your gas or electricity supply, and an engineer visit is not normally required. Your meters usually stay the same (unless you later choose a smart meter upgrade).

How long does a dual fuel switch take?

Switching times vary, but many UK switches complete within around 5 working days under the faster switching process. Complex cases (like meter issues or debt transfers) can take longer.

What details do I need to compare or switch dual fuel?

You’ll typically need your postcode, current supplier, tariff details (unit rates and standing charges), and estimated annual usage (kWh) or a recent bill. If you switch, you may also need your MPAN (electricity) and MPRN (gas) plus a meter reading on the day of the switch.

Can I keep my smart meter when switching dual fuel?

Usually yes. Many smart meters will keep smart functionality when you switch, though compatibility can vary. Even if smart features are limited temporarily, the meter will still work for energy supply and billing.

What if I’m on a prepayment meter—can I get a dual fuel tariff?

Often yes, though availability depends on the supplier and your meter type. Some dual fuel offers are for Direct Debit customers only, so it’s worth comparing options that specifically support PAYG/prepayment.

Are there exit fees for switching a dual fuel contract?

Some fixed dual fuel tariffs include exit fees if you leave before the contract ends, while variable tariffs often don’t. Check the terms for both fuels, as fees can apply per fuel or per account depending on the supplier.

How can I get the best dual fuel deal?

To get the best deal, compare the full annual cost for gas and electricity combined, based on your usage and region. Prioritise competitive unit rates and standing charges, choose a tariff type that suits your budgeting, and review contract terms before switching.

Why compare dual fuel tariffs?

A dual fuel comparison helps you understand your total energy costs, not just one part of the bill. It’s especially useful if your fixed deal is ending, you’ve moved home, or your household usage has changed.

One comparison, clearer choices

See gas and electricity tariffs together so you can judge the overall monthly cost and standing charges in your region.

Potential savings without disruption

Switching supplier shouldn’t mean switching off. Your supply continues, and you’ll usually just provide a meter reading around the switch date.

Support for fixed, variable & green

Compare fixed deals, standard variable tariffs, and renewable/greener options based on what matters most to your home.

How dual fuel switching works

Switching dual fuel in the UK is a managed process. Your new supplier coordinates the move, and you keep using energy as normal. The key is choosing a tariff that fits your household usage and avoids unnecessary fees.

Dual fuel tariffs explained (UK)

When you compare dual fuel, you’ll usually see a mix of tariff types. The best choice depends on how long you want price certainty, your appetite for risk, and your household usage pattern.

Tariff type	Best for	What to watch
Fixed rate	Budgeting and price certainty for a set term (e.g., 12–24 months).	Exit fees if you leave early; check what happens when the term ends.
Standard variable	Flexibility—often no fixed-term commitment.	Rates can change; compare standing charges and unit rates carefully.
Green / renewable-backed	Homes prioritising lower-carbon electricity options.	Confirm what “green” means on the tariff; check contract length and price.
Time-of-use (e.g., Economy 7)	Households that use more electricity off-peak (often with storage heating).	Day rate may be higher; ensure your usage pattern matches the tariff.

What makes up your bill?

Every tariff has two key parts: unit rates (pence per kWh) and a standing charge (daily fee). When comparing dual fuel, looking at both fuels together gives a more accurate picture of monthly cost.

Regional pricing matters

Prices can vary by region due to network costs. That’s why we ask for your postcode—it ensures you’re comparing deals that are actually available where you live.

Costs, savings & when to switch

A good dual fuel deal isn’t always the one with the lowest unit rate. Your best-value tariff is usually the one that matches your usage and minimises avoidable charges.

What can affect your quote?

Estimated annual usage (kWh) for gas and electricity
Your payment method (e.g., monthly direct debit)
Meter type (credit, smart meter, prepayment; Economy 7/10)
Your region and tariff availability
Any exit fees if you’re leaving a fixed-term early

Simple ways to reduce your energy spend

Set a realistic monthly direct debit and review it after seasonal changes.
Submit meter readings (or check your smart meter is sending data correctly) to avoid estimated bills.
If you’re low usage, compare standing charges closely—small differences add up over a year.
If you’re high usage, prioritise competitive unit rates and the right term length.

Not sure when your deal ends?

We can still help. Submit the form and tell us you’re unsure—then we’ll guide you through checking your current tariff and whether exit fees apply.

Regional & household considerations

England, Scotland & Wales

Tariff availability and pricing can differ by region. Your postcode ensures you’re comparing the right deals for your distribution area.

Flats, rentals & moving home

If you’ve just moved, you can still compare. Start by finding out who supplies the property, then consider a switch once your account is set up.

Smart meters & time-of-use

Smart meters can help with accurate billing and may support tariffs with different rates at different times. It’s still worth comparing the overall cost, not just peak/off-peak headlines.

Dual fuel comparison FAQs

Is dual fuel always cheaper?

Not always. Some homes do better with separate gas and electricity suppliers. A whole-of-market comparison helps you check the total cost both ways.

Will I lose supply if I switch?

No. Your energy keeps flowing. Switching is an administrative change handled by the suppliers. You may be asked for a meter reading around the changeover date.

Can I switch if I’m in debt?

It depends on your circumstances and meter type. Some suppliers can accept a transfer of debt arrangements. Submit the form and we’ll explain the options available to you.

What if I have a prepayment meter?

You can still compare, but availability may be more limited and pricing can differ. We’ll help you identify suitable dual fuel tariffs for your meter type.

How long does a switch take?

Timeframes vary by supplier and circumstances, but many switches complete within a few weeks. Your new supplier will confirm dates and next steps.
