How do I find the best dual fuel tariff in the UK?

Compare unit rates (p/kWh), standing charges (p/day), any exit fees, contract length, payment method, and customer service. Use your actual usage from recent bills for accurate quotes and focus on the estimated annual cost, not just headline discounts.

Should I choose a fixed-rate or variable dual fuel tariff?

Fixed tariffs lock in unit rates and standing charges for a set term, giving price certainty but may include exit fees. Variable tariffs can move up or down with the market and usually have no exit fees. Choose based on your risk tolerance and market outlook.

Will a smart meter help me save on a dual fuel plan?

A smart meter provides accurate, automatic readings and can unlock time-of-use or off-peak tariffs where available. Savings depend on your habits—monitor usage and shift consumption to cheaper periods to reduce bills.

What fees and terms should I check before switching?

Check early exit fees, contract length, payment method requirements (e.g., Direct Debit), any bill credit conditions, green/add-on premiums, and separate gas/electricity standing charges. Confirm whether rates can change due to regulatory adjustments.

How long does it take to switch dual fuel suppliers?

Most switches complete within about 5 working days (often faster under the Faster Switching programme), and you have a 14-day cooling-off period. Your supply will not be interrupted during the switch.

Are green or renewable dual fuel tariffs available?

Yes. Many suppliers offer renewable electricity and lower-carbon or carbon-offset gas options. Review how energy is sourced or offset (e.g., REGOs, biomethane, offsets) and compare total costs to standard tariffs.

Do dual fuel prices vary by region?

Yes. Network and wholesale cost differences mean unit rates and standing charges can vary by region. Always compare quotes using your postcode and actual usage.

Is paying by Direct Debit cheaper?

Many tariffs offer lower rates or standing charges for monthly Direct Debit than for payment on receipt of bill or prepayment. Check tariff details and ensure your Direct Debit reflects your actual consumption.

Can renters switch to a dual fuel tariff?

Usually yes, if you pay the energy supplier directly. Check your tenancy agreement for any clauses, but landlords cannot unreasonably prevent you from choosing your supplier. Take meter readings when you switch.

What to look for in a dual fuel tariff

Total estimated annual cost

Compare like-for-like using your usage or typical consumption. Unit rate and standing charge both matter, not just headline monthly price.

Contract length and exit fees

Fixed terms often include exit fees per fuel. Check fees for each fuel and whether they apply within the cooling-off period.

Payment method

Monthly direct debit is usually cheaper than pay on receipt or prepayment. Some suppliers offer credits for on-time payments.

Meter type

Single-rate, Economy 7 or 10, smart meters and prepayment meters all have different eligible tariffs. Choose one that matches your meter.

Green credentials

Look for renewable electricity, carbon offset gas, or REGO-backed tariffs. Some providers offer 100 percent green electricity as standard.

Customer service

Consider support hours, app features, and service ratings. Quick digital self-serve can make managing your energy much easier.

Tariff types explained

Fixed rate

Unit rates and standing charges are fixed for the term, giving predictable costs. Good if you value certainty. Check exit fees and end-of-term options.

Variable rate

Rates can go up or down, often linked to wholesale conditions and the Ofgem price cap. No exit fees on many standard variable tariffs.

Tracker or time-of-use

Some suppliers offer tariffs that track market indices or reward off-peak usage. Works best with smart meters and flexible consumption.

Green and bundle tariffs

Options include 100 percent renewable electricity, carbon-neutral gas, or bundles with EV charging credits, boiler cover or smart home perks.

Greener energy and smart meter benefits

Smart meters enable accurate bills, in-home displays and access to time-of-use or demand-flexibility rewards.
Renewable electricity tariffs support generation from wind, solar and hydro via REGO certificates.
Pair smart controls and efficient appliances to shift usage away from peak times and cut costs.

Fees, discounts and the small print

Standing charges: a daily fee per fuel that applies regardless of how much energy you use.
Exit fees: check if there is a fee per fuel and whether it is waived when you switch within the last 49 days of a fixed term.
Price caps: variable tariffs in Great Britain are limited by the Ofgem price cap methodology; your exact bill still depends on usage.
Warm Home Discount and support: see if you are eligible for government or supplier schemes that reduce bills.
Billing and credits: confirm how and when any joining credits or referrals are applied to your account.

Renters, prepayment and Economy 7

Renters

If you pay the bill, you can usually choose the supplier. Check your tenancy for any clauses and agree meter readings with your landlord.

Prepayment meters

Prepay tariffs have different unit rates and top-up rules. Some suppliers let you switch to credit meters following a quick check.

Economy 7 and 10

Multi-rate meters charge less overnight and more in the day. Best for homes with storage heating or heavy off-peak use.

Moving home

Tell both suppliers your move dates and readings. You can switch at your new address right away once your account is set up.

Dual fuel FAQs

What is a dual fuel energy deal?

A dual fuel deal combines your gas and electricity with the same supplier, usually under one contract and one monthly payment.

Is dual fuel always cheaper?

Not always, but suppliers often bundle value or discounts. The best option depends on your usage, meter type and region. Compare both dual fuel and single-fuel quotes to be sure.

Can I switch if I am in credit or debt with my current supplier?

You can usually switch if your debt is below a certain threshold or is being repaid on an agreed plan. Your final bill will reconcile any credit or debit balance.

Will my energy be cut off during the switch?

No. Switching is administrative only. Your gas and electricity continue without interruption.

Do exit fees apply when I switch?

Some fixed tariffs include exit fees per fuel. Fees are often waived in the final 49 days of your contract. Check your tariff terms before switching.

How do smart meters affect my tariff?

Smart meters enable accurate billing and access to time-of-use or tracker tariffs. You can still choose a fixed or variable plan with a smart meter.

Are quotes available across the whole UK?

Switching and the Ofgem price cap apply in Great Britain: England, Scotland and Wales. Northern Ireland has a separate market with different rules and suppliers.

What info do I need to get an accurate quote?

Your postcode, current supplier, meter type and usage from a recent bill will give the most accurate results. If you are not sure, we can estimate.

Important information

Energy prices and tariff availability change frequently. Any example costs are illustrative only; your actual bill will depend on your usage, location and chosen plan. Variable tariffs in Great Britain may be affected by the Ofgem price cap methodology. Always read the tariff terms and conditions before switching. We aim to show accurate information but cannot guarantee completeness or that a particular tariff will be the cheapest for every household.
