Why switch?

Many people think switching energy supplier is a hassle and they don’t believe it will save them money, but you could make big savings, especially if you’ve never switched before. There are three basic steps:

  • compare your tariff with other deals on offer
  • choose the best deal
  • tell the new supplier you want to switch and they’ll organise the change for you.

It’s a fairly simple process but it can seem daunting and you need to make sure you have the right information before you begin.

Understanding your bill

Before you start, you should check how much energy you use. Your energy supplier must give you personalised information on your bill which explains what tariff you‘re on, your energy use and details of any exit fees. Citizens Advice has a useful tool to help you understand your energy bill.

Choosing the right tariff

The different energy deals are known as tariffs and there are many types. The most common are:

  • fixed – the price of your energy is fixed for the duration of your contract
  • capped – the price may go up or down but it won’t go over a set limit
  • standard or variable – the price depends on the market and may go up or down.

Fixed and capped tariffs are usually the cheapest and can help you to budget better but there may be a fee if you want to leave the contract early. There is no end date with a standard or variable tariff and no exit fee if you switch.

You may pay less if you pay by direct debit, manage your account online or opt for a dual fuel (gas and electricity) tariff. You should check any deals or discounts carefully and also consider the service offered by the supplier.

The energy market is regulated by Ofgem and their Go Energy Shopping website has information to guide you if you’re thinking of switching.

Compare prices

The best way to compare prices and deals is by using online price comparison websites. You should check two or three. Some price comparison websites have been accredited by Ofgem. You could also use the comparison tool on the Citizens Advice website.

Be wary of sales people who offer deals face-to-face or on the phone. Don’t be pressured into signing anything and take your time to consider any offers. 

If you find the deals on offer confusing, you can get help from your local Citizens Advice.

How to switch

You can switch online or over the phone. You just tell the new supplier you want to switch and they will contact your current supplier to organise the change. It shouldn’t take longer than 21 days.

You’ll need:

  • your postcode
  • the name of your current supplier
  • the name of your current energy deal and how much you spend
  • an up-to-date meter reading
  • your bank details if you’re paying by direct debit

You may also need your Meter Point Access Number (MPAN) and your Meter Point Reference Number (MPRN). You’ll find most of this information on your bill.

Make sure you take a meter reading the day before you switch. You should receive a final bill from your current supplier within six weeks and if they owe you any money, you should get a refund soon after that.

There is a 14-day cooling off period in case you change your mind. If you cancel during this period, you’ll stay with your current supplier.

Some suppliers have agreed a voluntary list of commitments, called the Energy Switch Guarantee, which should make switching easier. Check to see if your supplier has signed up.

Things to be aware of

If a supplier offers to reduce your direct debit, this doesn’t mean they‘re reducing the amount you pay for your energy. If you use more energy than your direct debit covers, you could end up with a big bill later.

You could lose your warm home discount if you switch to a smaller supplier. Only suppliers with more than 250,000 customers are legally obliged to offer this, so check before you switch.

You might not be able to switch if you:

  • rent – check your tenancy agreement to see if you should ask your landlord first
  • owe money to your supplier.

Other ways to save

Switching supplier is not the only way to save money on your energy bills. If you think you’re paying too much, contact your current supplier to make sure you’re on the best tariff for you. Your bill must give information about their cheapest tariff and how much money you could save.

You could also ask your supplier what support they offer for older people. You may qualify for free services such as gas safety checks if you put yourself on their Priority Services Register. Some suppliers also offer financial assistance for people on a low income and you may be able to get a grant to replace your boiler, for example.  

You could also make savings if you:

  • use energy-saving light bulbs and switch off lights when you leave the room
  • don’t leave appliances on standby or on charge unnecessarily
  • close your curtains at dusk to keep the heat in
  • turn the radiators down - or off - in rooms that you don’t use very often
  • draught-proof your windows, doors and loft hatches
  • choose energy-efficient appliances.

You can find more tips on the Energy Saving Trust website. You could also do a home energy check.

If you’re having trouble paying your bills

If you’re struggling to pay your bills, contact your supplier. They must help you to work out a solution, such as a payment plan.

You can’t have your gas or electricity cut off between 1st October and 31st March if you are a pensioner and you live:

  • alone
  • with other pensioners
  • with a child under the age of 18.

Make sure you’re claiming all the benefits you’re entitled to, such as the Winter Fuel Payment.

Some energy suppliers offer grants and financial assistance to vulnerable customers. You don’t necessarily have to be with that supplier to qualify. Contact Charis for more information.

Don’t ignore any debt recovery letters. If you’re in debt, get advice.
