Why compare gas and electricity prices for your home?
Cut your monthly bills
UK energy prices have risen sharply in recent years, but there are still meaningful savings available when you choose the right tariff for your usage. Comparing home energy prices helps you avoid expensive standard variable rates and keep more money in your pocket.
Get price certainty
If you prefer predictable bills, a competitive fixed rate tariff can lock in your unit rates and standing charges for 12–24 months. We highlight fixed, variable and flexible tariffs so you can balance price stability with potential savings.
Choose greener energy
Many suppliers now offer 100% renewable electricity and carbon-offset gas tariffs. Our comparison makes it easy to spot green and low-carbon options, so you can lower your home’s carbon footprint while staying in control of your costs.
How our home energy price comparison works
- Share a few details about your home. Tell us your postcode, property type, whether you use gas, electricity or both, plus your current supplier and typical usage or spend. The more accurate the information, the more precise your comparison will be.
- We search tariffs from a range of UK suppliers. Using your details, we check current gas, electricity and dual fuel tariffs available for your area, including fixed, variable and green deals.
- Review tariff options tailored to you. We help you compare estimated annual costs, unit rates (pence per kWh), standing charges, contract length, exit fees, payment method and any extras like smart meter requirements or rewards.
- Choose your new tariff and switch. If you decide to go ahead, we handle the switching process with your new and old suppliers. There is no interruption to your gas or electricity supply and no engineer visit is usually required.
- Enjoy cheaper, better-matched energy. Once your switch completes (typically 2–21 days depending on supplier and cooling-off periods), you simply pay your new supplier and benefit from the new tariff.
What you’ll need to compare accurately
- A recent gas or electricity bill
- Your annual kWh usage or monthly spend
- Your full postcode
- Property type and number of bedrooms
- How you pay now (Direct Debit, prepayment, on receipt of bill)
Don’t worry if you don’t have all the details to hand – we can still give you an indicative comparison based on typical usage for a property like yours.
Understanding UK home gas and electricity tariffs
Fixed vs variable tariffs
A fixed rate tariff keeps your unit rate and standing charge the same for the duration of the contract, usually 12–24 months. Your monthly Direct Debit may still change to reflect your actual usage, but the price you pay per kWh will not increase or decrease during the fixed period.
A variable tariff can go up or down at your supplier’s discretion, usually in line with changes to wholesale energy prices and the Ofgem price cap. These tariffs are often more flexible and may not charge exit fees, but they offer less price certainty.
Dual fuel vs single fuel
With a dual fuel tariff, you purchase both gas and electricity from the same supplier. This can simplify your bills and, in some cases, offer discounts or rewards.
You can also choose single fuel tariffs where your gas and electricity come from different suppliers. This can sometimes work out cheaper overall, especially if one supplier is particularly competitive on electricity or gas in your region.
Standard variable tariffs and the price cap
If you have never switched, or if your fixed deal has ended, you’re likely on a standard variable tariff. These tariffs are usually more expensive than the best deals on the market but are limited by the Ofgem energy price cap.
The price cap limits what suppliers can charge per unit of energy and for the standing charge on standard variable tariffs. It does not cap your total bill – that still depends on how much energy your household uses. Comparing tariffs helps ensure you’re not paying more than you need to.
Smart meters and time-of-use tariffs
Smart meters automatically send your usage to your supplier, making bills more accurate and giving you better visibility of when you use energy. Some tariffs require a smart meter or offer discounts if you have one.
Time-of-use tariffs (like Economy 7, Economy 10 or off-peak electric vehicle tariffs) charge different rates at different times of day. These can be cost-effective if you can shift usage to off-peak times, for example by running appliances or charging an EV overnight.
How to get the best value from your home energy
Price alone isn’t the only factor when you’re comparing gas and electricity. The right tariff for your household will depend on how and when you use energy, your payment preferences and your priorities around green energy and customer service.
Key points to consider when comparing tariffs
- Unit rate (p/kWh): The price you pay for each unit of gas or electricity used. Lower isn’t always better if the standing charge is very high, so look at the overall estimated annual cost.
- Standing charge: A daily fee just for being connected to the energy network. This can vary significantly between suppliers and tariffs.
- Contract length & exit fees: Longer fixes can give certainty but may carry higher exit fees if you want to leave early. Check the small print before committing.
- Payment method: Paying by monthly Direct Debit is often cheaper than on receipt of bill or prepayment meters.
- Online-only vs full service: Some of the cheapest tariffs are online-only with app-based support, while others offer phone-based customer service and more flexible billing.
- Green credentials: If sustainability matters to you, look for 100% renewable electricity, carbon-offset gas, or suppliers with strong environmental commitments.
Simple ways to reduce your energy usage
Switching to a better tariff is just one part of cutting your bills. Small efficiency improvements can make a big difference over the year:
- Turn your thermostat down by 1°C – this can cut heating costs by around 10%.
- Swap halogen bulbs for LEDs and always switch lights off when not needed.
- Avoid standby where possible – unplug chargers and devices when not in use.
- Use shorter showers and lower temperature washes on your washing machine.
- Keep fridges and freezers at recommended settings and defrost regularly.
Our energy specialists can also offer guidance on grants and schemes that may help with insulation, heat pumps, or other home energy upgrades.
Frequently asked questions about home energy comparison
Is it still worth switching gas and electricity supplier?
Yes – even with the energy price cap in place, different suppliers and tariffs can vary significantly. Some households may find that sticking with their current supplier is best, but many can still lower their bills, fix their rates or move to a greener tariff by comparing what’s available.
Will my gas or electricity be cut off during the switch?
No. Your home will not lose power or gas supply when you switch. The process is managed behind the scenes between your old and new suppliers, using the same pipes and cables. You will simply start receiving bills from your new supplier once the switch completes.
How long does it take to switch home energy supplier?
Most switches complete within 2–21 days, depending on the supplier and any cooling-off periods. You will receive confirmation from your new supplier with exact dates, and they will usually ask you for opening meter readings to make sure your final and first bills are correct.
Do I need a smart meter to switch?
No, you don’t have to have a smart meter to switch suppliers, although some tariffs are only available if you have one or are willing to have one installed. If you already have a smart meter, it may continue to work in smart mode after switching, depending on the technology and your new supplier.
Can I switch if I’m in debt to my current supplier?
If you are on a standard credit meter and have been in debt to your supplier for less than 28 days, the debt will usually be added to your final bill and you can still switch. For longer-term debt or prepayment meters, there are additional rules – we can talk you through your options.
Will my landlord or letting agent need to approve a switch?
If you are responsible for paying the energy bills directly, you usually have the right to choose your supplier. Check your tenancy agreement, and let your landlord or agent know you are switching so they can update their records if needed.
