You could pay less for the same energy

Follow our tips below to get a fairer price for your energy.

Fix your gas and electricity costs

Fix your gas and electricity costs

Find a fixed, cheap energy deal for your gas and electric prices and stay on it. Fixed energy tariffs lock in your price-per-unit (kWh) of energy, which means you're protected against energy wholesale price hikes, giving you complete peace of mind. If you're on a variable tariff, your price per kWh can vary along with the price cap.

Don't let your fixed tariff expire

Don't let your fixed tariff expire

Your fixed tariff has an expiry date. If you let it run its course, you may no longer be on a competitive rate. This is because you'll automatically be put on your energy supplier's default tariff, which is likely to be the most expensive they'll have to offer. Remain vigilant, and switch away before your fixed gas and electricity tariff expires.

Compare energy prices every 3-6 months

Compare energy prices every 3-6 months

The energy market is always changing, with suppliers introducing cheap energy deals regularly. To ensure you're paying the best price for your energy, we recommend you compare energy prices every 3-6 months. If you find something cheaper, change energy suppliers, but if not, it's always worth knowing what else is out there.

Where can I find helpful, independent information and advice about energy efficiency?

If you’re looking for some really useful advice on energy efficiency then visit Energy Saving Trust, Citizens Advice and the Government’s energy grants calculator.

The Energy Saving Trust is a leading, trusted organisation helping people save energy on a daily basis.

Citizens Advice is a renowned service in the UK which provides free assistance and guidance on a range of subjects, including energy.

The Government's energy grants calculator offers personalised energy efficiency advice based on your postcode, and relevant information such as available grants.

After switching suppliers, what do I need to do?

Once you've made a decision on which energy supplier you'd like to switch to, we will send you a confirmation email outlining the details of your new tariff.

From here, we will send on your application to your new supplier who will notify your current supplier that they are taking over and shortly after will notify you of your supply start date with them. You must ensure that you take a meter reading on your supply start date, so that you are billed the correct amount.

If your new supplier is part of the Energy Switch Guarantee, then you should be waiting no more than 21 days for your tariff to be switched.

How do I find out my current supplier?

You should be able to find who your current energy supplier is by taking a look at your most recent utility bill. Your supplier's logo and name should be clearly visible on there.

Another way of finding out your current energy supplier is by taking a look at your last energy payment on your bank statement, and it should say the supplier name there too.

You can find out who your electricity supplier is by contacting your regional Distribution Network Operator (DNO), the company that owns and maintains the electricity grid in your area. Contact them and ask them for their Meter Point Administration Service (MPAS) and tell them your postcode and address, and they'll be able to tell you the current electricity supplier for your property.

We’re Energy Helpline, the energy comparison service.

We exist to find you cheap energy by helping you find the best energy deals on the market, and you’ll hardly have to lift a finger.

No other energy comparison service compares more energy suppliers here in the UK than we do. This means that when you use us, you’re seeing the full picture of the energy market - we leave no stone unturned. So when we know what we need to know about your current energy supply, we’ll bring up all the suitable alternatives available to you via Energy Helpline at the time of your energy comparison. You either choose one and begin your energy switch, or you can come back another day. It’s entirely up to you. When you choose which energy supplier and energy deal you’d like to switch to, we’ll handle the rest of your energy switch.

  • Who is Energy Helpline?

    Energy Helpline is an independent energy comparison service that began life back in 2002. Our mission is to ensure that energy switching is swift, simple and absolutely hassle-free.

    Our price comparison service is Ofgem-accredited, which means you can be sure that the prices and options displayed have been calculated fairly in an unbiased way.

    We’re honest, impartial and dedicated to seeing you save money on your energy bills.

  • Will I be charged a cancellation fee for leaving my current supplier?

    This depends on your current tariff terms and conditions, as well as your contract status. Some tariffs simply don’t have exit fees, and that’s a selling point used to make them more appealing. Your current supplier will be able to tell you if you have any exit fees to pay for leaving.

    The type of energy tariff you are on can determine whether or not you pay any exit fees when switching your energy supplier, too. If you’re on a standard variable tariff you can switch without incurring any fees, however, if you’re on a fixed term plan you’ll most likely be charged when leaving your current supplier. Although, when you receive your notice 49 days before the end of your fixed-term tariff, suppliers cannot charge a termination fee if you choose to switch after this point.

    Sometimes cancellation fees are dependent on your supplier, too. There are now some energy suppliers out there that have chosen to completely scrap cancellation fees, giving them an advantage over the ones that do.

  • How long is my cooling-off period?

    No matter which supplier or tariff you choose, your cooling-off period is always 14 days, starting from the day after you agree to the contract with your new energy supplier.

    This means that if you have a change of heart after you've decided to switch your energy supplier to a cheaper one, you have 14 days to cancel the switch and remain with your original energy supplier.

  • What happens if I'm moving house?

    There are certain steps you need to take when switching energy suppliers when moving house. Don't worry, we've outlined them clearly below.

    Before you move make sure you:

    • Let your supplier know that you're moving, by giving them at least 48 hours notice.
    • Read your readers on moving out day, and give the readings to your supplier. Keep a note of them in case you don't agree with your final bill.
    • Give your supplier your new address so they can send you your final bill.

    After you move make sure you:

    • Contact the current supplier of your new property to tell them you've moved in.
    • Read the meters and give them to the current supplier to make sure you get an accurate first bill.
    • Pay the bill when you get it.

    We recommend looking to switch immediately when moving home. As it takes 21 days to switch, you will always have to pay at least one of your existing property’s bills, so switch away to make sure you don’t pay any more!

  • Why should I switch suppliers?

    You should look to switch energy suppliers because there's money to be saved with cheap deals!

    Whilst we can't guarantee that we'll be able to find you a cheaper deal, it's well worth checking. It only takes a few minutes of your time, and we'll be able to tell you today whether we think you could be paying less for energy. There's no reason to keep overpaying, especially when switching with us is so simple and free.

    Switching also opens your eyes up to what else is out there on the market. No other comparison site compares more UK energy suppliers than us, so we can give you a really accurate picture on how cheap some energy deals can be. Once you've switched and saved once, you'll want to stay up to date, and eventually switch again to save more!

    You'll also be fixing your price if you move to a fixed tariff, which means that you won't be subject to price rises during your new contract. So you can sit back and relax knowing you've saved yourself some hard-earned cash, without having to worry about wholesale energy prices for the length of your fixed contract!

Will my energy supply be interrupted if I switch?

No, your current energy supply will, in no way, be interrupted.

Your actual energy supply is not changing, so there won't be any interruption. Everything happens behind the scenes, so if you've picked a cheaper deal through us then the only difference you should notice will be your energy bills going down.

How long does it take to switch energy suppliers?

Ofgem has rules in place requiring suppliers to take reasonable steps to ensure a switch happens within 21 days. There are exemptions, but generally you should expect your switch to be fully processed within that 3-week time frame.

Do I need to contact my current supplier if I want to switch?

If you're switching energy and using a reputable comparison service like Energy Helpline, there's no need to contact your existing supplier - everything is handled for you.

If you were to switch through us, once you've chosen the energy tariff you'd like to switch to, your current supplier will be notified automatically.

You might need up-to-date meter readings, but your new supplier should contact you to ask for these during your switchover.

Is there any obligation to switch?

Definitely not, calling us or visiting our website does not lock you into a new tariff. We are here to provide you with all the information you need, and you can take as much time as you need before making a decision.

A lot of customers use our service to simply see what cheap deals are out there, as it saves them from trawling through dozens of supplier's sites and doing it all themselves.

Are there any hidden costs?

Absolutely not, our energy switching service is free for all customers. This covers everything from visiting our website or calling our UK-based call centre, and switching to your new supplier. From start to finish, switching energy suppliers with us is free!

We are here to provide you with our best deals available in your area. No other energy comparison service compares more.

What type of energy deals are there?

If you’re looking to change energy suppliers, there are plenty of cheap deals on the market. Rather than looking for the best energy supplier, it might be worth looking for the best energy deals, instead. There are plenty on the market, you just have to decide which one suits your needs.

Standard variable tariff (SVT)

Standard variable tariffs (SVT) are also known as default tariffs, and are often the deal your energy supplier puts you on if you haven’t specified your preferred energy deal. Check with your energy supplier if you don’t know what deal you’re on, and if you find out you’re on an SVT, you could most likely save money with a cheaper energy deal by switching.

Green energy tariff

Some suppliers offer 100% renewable electricity, putting naturally-sourced energy back into the grid. A supplier might also fund international projects that help tackle carbon emissions to offset the gas their customers use. These suppliers will still offer standard tariff-types, just with the premise of generating 100% renewables to fuel them.

Economy 7 tariff

An Economy 7 tariff can help you get cheaper energy by giving you cheaper energy rates for a seven hour window during the night, but the price-per-unit of energy can vary depending on your energy supplier. Due to the cheaper energy rates at night, Economy 7 day-rates tend to be much higher than regular energy tariffs, often leading to expensive bills.

Electric or gas-only tariff

Your premises might be gas-only or electric-only, so you’ll be after a single-energy tariff. But, signing up for energy separately could help you save money, if you’re willing to compare two single-energy tariffs against a dual fuel tariff. This means more hassle for you, but going with two different suppliers for your energy might be worth it in the long run.

Fixed rate tariff

Fixed rate tariffs lock in the price you pay per unit of energy (kWH) for a certain period of time, protecting you from wholesale energy price hikes. They also offer some of the cheapest prices on the energy market, ensuring you pay a fair price for your energy for a lengthy amount of time and allowing you to forget about energy price rises.

Prepayment meter tariff

Prepayment meters are installed in your home, allowing you to become a ‘pay as you go’ energy customer. Prepayment meters are powered by a ‘key’ or smart card that is topped up and inserted into the meter to power it. Whereas credit meters allow you to spread energy cost evenly over the year, prepayment meters require you to pay for exact use.

Dual-fuel tariff

A dual fuel tariff means that you can purchase both your gas and electricity from the same supplier in the same energy tariff, which is a lot more convenient for you. Having a dual fuel energy tariff often means that your overall energy supply is cheaper, but to be sure it is, run a price comparison before you switch to make sure.

Feed-in tariff

This type of energy deal is a product of the Feed-in Tariffs (FIT) government scheme designed to promote and encourage the implementation of renewable and low-carbon electricity generation technologies. A feed-in tariff is available for anyone who has installed their own method of renewable energy generation, such as solar panels.
