If you're searching for how to compare gas and electricity prices, you’re in the right place. At EnergyPlus, we help UK households compare and switch to the best dual fuel tariffs — all in under 5 minutes.

Why compare gas and electricity together?

Opting for a dual fuel tariff—where one supplier handles both gas and electricity—can offer more convenience, clearer billing, and often better prices. However, the cheapest option depends on more than just headline rates. Several factors influence your total cost, such as standing charges, exit fees, smart meter compatibility, and regional price differences. :contentReference[oaicite:0]{index=0}

Dual Fuel Tariffs: Advantages & Disadvantages

Advantages

  • Often lower prices or discounts for bundling gas and electricity. :contentReference[oaicite:1]{index=1}
  • Single monthly bill, one supplier contact point, and simplified billing. :contentReference[oaicite:2]{index=2}
  • Easier comparison and switching process when fuel supplies are consolidated. :contentReference[oaicite:3]{index=3}

Drawbacks

  • Dual fuel is not always cheaper than separate gas and electricity contracts — always run separate comparisons. :contentReference[oaicite:4]{index=4}
  • Fixed dual fuel plans can come with exit fees if you leave early. :contentReference[oaicite:5]{index=5}
  • Supplier discounts and tariff conditions may vary dramatically by region or meter type. :contentReference[oaicite:6]{index=6}

What affects your gas and electricity bills?

The total cost of your energy depends on multiple components, not just the unit price (pence per kWh). Here are the main factors to watch:

  • Unit rates for gas and electricity — how much you pay per kWh of usage.
  • Standing charges — daily fixed costs for having a gas or electricity supply connected. These can vary widely and even outweigh savings from low unit rates. :contentReference[oaicite:7]{index=7}
  • Exit or cancellation fees if you leave a fixed-term contract early.
  • Smart meter discounts or requirements — some deals only apply if you have a smart meter. :contentReference[oaicite:8]{index=8}
  • Payment method — paying by direct debit is often cheaper than standard credit or prepayment. :contentReference[oaicite:9]{index=9}
  • Regional price variations — rates can differ by region, postcode, or supplier area. :contentReference[oaicite:10]{index=10}

Average UK Energy Costs (2025)

According to Ofgem, the typical annual cost for a dual fuel household paying by direct debit is about £1,720 between July and September 2025. :contentReference[oaicite:11]{index=11} However, actual bills will vary depending on usage — with higher consumption homes often paying significantly more. :contentReference[oaicite:12]{index=12}

That figure represents a drop from earlier in the year thanks to wholesale price changes and updated price cap levels. :contentReference[oaicite:13]{index=13} Still, there are dual fuel plans priced well below the price cap, underscoring the value of comparison and switching. :contentReference[oaicite:14]{index=14}

How to Compare Gas and Electricity Prices Effectively

  1. Gather your current information — check your latest bill for usage, meter type, supplier, and payment method. :contentReference[oaicite:15]{index=15}
  2. Enter your postcode in a trusted comparison tool to view personalised quotes. :contentReference[oaicite:16]{index=16}
  3. Look beyond the headline price — check unit rates, standing charges, exit fees, and the impact of smart meters. :contentReference[oaicite:17]{index=17}
  4. Consider your contract type — fixed, variable or flexible tariffs all have pros and cons depending on energy price forecasts and your usage. :contentReference[oaicite:18]{index=18}
  5. Factor in payment and billing preferences — direct debit, prepayment or credit billing can change your total cost. :contentReference[oaicite:19]{index=19}
  6. Review potential savings — compare the estimated cost of staying on your current plan versus switching. Look especially for options that beat the Ofgem price cap. :contentReference[oaicite:20]{index=20}

Frequently Asked Questions (FAQs)

Is a dual fuel tariff always cheaper?

Not necessarily. While dual fuel plans often include bundle discounts and convenience, they’re not always the cheapest option. In some cases, taking separate gas and electricity tariffs could save more, depending on your consumption, payment method, and location. :contentReference[oaicite:21]{index=21}

When should I switch gas and electricity suppliers?

The best time to switch is usually before a fixed-term tariff ends or when energy price cap announcements are coming. It’s also worth reviewing your plan at least once a year to check you’re not on a costly default or standard variable plan. :contentReference[oaicite:22]{index=22}

Will switching interrupt my energy supply?

No — switching gas and electricity suppliers should not interrupt your service. The new supplier will manage the switch, and your meter will stay the same. :contentReference[oaicite:23]{index=23}

Do I need a smart meter to switch or save money?

Not always, but smart meters can make your energy billing more accurate and might unlock certain tariff discounts. Some fixed or online-only tariffs assume you have a smart meter already installed. :contentReference[oaicite:24]{index=24}
