Why compare UK home energy suppliers?
Every UK household uses energy differently. The size of your home, how well it is insulated, how many people live there and the times you use heating or appliances will all affect your gas and electricity usage. Energy suppliers offer a wide range of tariffs and deals, and the tariff that is cheapest for one household may not be the best for another.
Comparing home energy suppliers lets you see which tariffs align with your usage patterns and priorities. Whether you are on a standard variable tariff that has crept up in price, or coming to the end of a fixed-rate deal, switching suppliers or tariffs can often reduce your bills and give you more control over future costs.
Competition between suppliers also means there are regular introductory offers, fixed-rate deals and renewable energy plans designed to win new customers. If you stay with the same supplier without reviewing your tariff, you may miss out on savings or deals that better suit your home.
Cut your monthly bills
By comparing prices from multiple UK suppliers you can identify cheaper tariffs for your typical energy use, helping reduce monthly direct debits or pay-on-receipt bills.
Gain price stability
Many households prefer the certainty of a fixed-rate tariff. Comparing deals lets you lock in a competitive unit rate for 12 months or more, protecting you from price rises.
Choose greener energy
Find suppliers offering 100% renewable electricity, carbon-offset gas and smart tariffs that reward you for using energy at off-peak times, helping you cut emissions as well as costs.
How home energy switching works
Switching your home energy supplier in the UK is straightforward and is regulated by Ofgem to protect households. The physical gas and electricity that reaches your home does not change; only the company that bills you and manages your tariff changes. This means there is no need for engineers to visit and there is no interruption to your supply.
Once you choose a new tariff, your new supplier handles the switching process on your behalf. They will contact your existing supplier, agree a switch date and confirm your final meter readings. You simply continue to receive energy as normal and start paying your new tariff when the switch is complete.
Most switches complete within 5 to 21 days, depending on the supplier and whether you also choose to have a smart meter installed. Any credit on your old account is usually refunded, and if you are in debt to your current supplier you may still be able to switch under the Energy Switch Guarantee, subject to certain conditions.
Simple steps to compare and switch
- Share your details: Provide your postcode, property type and current supplier details so we can estimate your usage and available tariffs.
- Review personalised deals: See tariffs from a range of UK home energy suppliers, including fixed, variable, dual fuel and green options.
- Choose your tariff: Compare expected monthly costs, unit rates, standing charges and contract lengths to select the best fit for your household.
- Confirm your switch: Complete the short online process. Your new supplier will arrange the switch and keep you updated on progress.
- Submit meter readings: Provide meter readings when requested so your old and new suppliers can issue accurate final and opening bills.
Throughout the process you remain protected by UK consumer regulations, and you will have a cooling-off period to change your mind after confirming a new contract.
Types of UK home energy tariffs you can compare
Different tariffs suit different households. When you compare UK home energy suppliers you will typically see a range of tariff types. Understanding how each works can help you choose the most suitable deal for your budget and risk appetite.
Fixed-rate tariffs
With a fixed-rate tariff, the price you pay per kWh of gas and electricity, and your standing charge, are fixed for an agreed period, usually 12, 18 or 24 months. Your monthly payments may still change based on usage, but the underlying unit rates remain stable.
Fixed tariffs are popular with households that want predictable pricing and protection from market increases. However, if wholesale energy prices fall, you may not benefit until your fixed term ends or you switch again.
Variable-rate tariffs
Standard variable tariffs (SVTs) and other variable deals allow your supplier to change prices, usually in response to wholesale market conditions and regulator rules. Your unit rate and standing charge may move up or down over time.
Variable tariffs can offer flexibility and no exit fees, making it easier to move to another deal when you find a better offer. However, you are more exposed to price rises, so it is important to monitor your tariff regularly.
Dual fuel tariffs
If your home uses both gas and electricity, a dual fuel tariff allows you to get both from the same supplier. Many UK providers offer discounted rates or simpler billing when you combine your gas and electricity into one account.
Dual fuel is convenient for households that prefer dealing with a single company for all their home energy, though it is still worth comparing separate gas and electricity deals to check which option works out cheaper overall.
Green and renewable energy tariffs
Green tariffs are designed for households that want to support renewable energy generation or reduce their carbon footprint. Many suppliers now offer 100% renewable electricity backed by Renewable Energy Guarantees of Origin (REGOs), and some provide carbon-offset or bio-gas options.
Some green tariffs are competitively priced with standard deals, while others may cost slightly more but provide stronger environmental benefits. Comparing green energy suppliers helps you balance cost with sustainability.
Smart meter and time-of-use tariffs
With a smart meter installed, you may be offered time-of-use tariffs, such as Economy 7, Economy 10 or other off-peak deals. These tariffs charge different rates at different times of the day, rewarding you for shifting usage to off-peak periods.
For households with storage heaters, electric vehicles or flexible routines, time-of-use tariffs can generate meaningful savings. When comparing suppliers, consider whether your lifestyle allows you to benefit from cheaper off-peak rates.
Prepayment and pay-as-you-go tariffs
Prepayment meters let you pay for energy in advance using a key, card or app. While they can help some households manage budgets, prepayment tariffs have historically been more expensive than direct debit deals.
If you currently use a prepayment meter, comparing suppliers may reveal options to switch to credit billing, which can often reduce your long-term costs, subject to eligibility and supplier approval.
What to consider when comparing home energy deals
Price is important, but it should not be the only factor when choosing a home energy supplier. A slightly cheaper tariff may not be worth it if customer service is poor or exit fees are high. As you review your options, keep these key factors in mind.
Unit rates & standing charges
The total cost of your energy bill depends on both the price per kWh and the daily standing charge. A low unit rate with a high standing charge may suit high-usage households, while low standing charges can favour lower-usage homes such as small flats or part-time residences.
When you compare deals, look at the estimated annual cost based on your expected usage rather than focusing on one number in isolation.
Contract length & exit fees
Fixed-term contracts often include exit fees if you leave before the end date. While these charges are usually modest, they can reduce the benefit of switching again soon. Check the length of the contract and any early termination fees before committing.
If you expect your circumstances to change, or you prefer flexibility, a variable or shorter fixed-term tariff may suit you better.
Customer service & digital tools
Good customer service can make a big difference if you ever need support, want to change your payments or query a bill. Many UK suppliers now offer helpful apps, online dashboards and usage alerts to help you monitor and manage your energy more effectively.
Checking independent reviews and considering how you prefer to manage your account (online, app, phone or post) can help you choose a supplier that matches your expectations.
Green credentials & ethical policies
If sustainability matters to you, review how each supplier sources electricity and gas, and whether they invest in renewable projects or energy efficiency initiatives. Some providers publish detailed reports on their fuel mix and emissions.
Choosing a supplier with strong environmental policies can help reduce the carbon impact of your household energy use while still keeping an eye on cost.

Start your home energy comparisonFrequently asked questions about switching home energy
Will my gas or electricity supply be interrupted when I switch?
No. Your physical supply will continue as normal during and after the switch. The gas and electricity reaching your home is delivered through the same pipes and wires, regardless of which supplier bills you. Only your tariff and account details change.
How long does it take to switch home energy supplier?
Most switches are completed within 5 to 21 days, depending on the suppliers involved and whether you request a new smart meter. You will be given an estimated switch date and your new supplier will keep you updated throughout the process.
Do I have to pay exit fees to leave my current tariff?
Some fixed-rate tariffs include exit fees if you leave before the contract end date. Check your latest bill or contact your current provider to confirm any charges. In many cases, potential savings from a better tariff may still outweigh these fees.
Can I switch if I have a smart meter?
Yes. You can usually switch suppliers even if you already have a smart meter installed. In some cases your smart meter may temporarily operate in non-smart mode, but your new supplier should explain how they will support smart features going forward.
What information do I need to compare home energy deals?
To get the most accurate comparisons, it helps to have a recent bill showing your tariff name, current supplier, payment method and annual usage in kWh. If you do not have this, we can estimate usage based on your property type and typical household size.
Can I switch if I am renting?
If you pay the energy supplier directly, you can usually switch, even as a tenant. If energy is included in your rent, or billed via your landlord, you may need to discuss any changes with them first. Always check your tenancy agreement for details.
