Why would I need to find my energy supplier?

Whether you’ve just moved to a new house, you’re a new tenant, your energy supplier has just been sold to another company, or just don’t remember the particulars of your household bills, it’s important that you keep up to date with who your current energy supplier is. 

There are plenty of good reasons why you should find out who supplies your gas and electricity:

To help you compare energy prices to see if switching to a new supplier would be a good move.

Who’s my energy supplier?

Energy suppliers provide electricity and gas to your home – the same utility company may supply both or you may use different suppliers for different fuels. Your supplier may be a well-known name, one of the so-called ‘big six’ energy suppliers or a smaller company, but you shouldn’t assume you know who it is. Read on to discover how to confirm – or find out – who supplies your electricity and gas.

How do I find my electricity supplier?

Start by looking for your latest electricity bill – this may be mailed to you in the traditional way, sent via email, or you may have been given information about logging into an account on your electric supply company’s website.

If you’ve just moved to a new home, then the previous owner should have reported the move to prevent being billed for energy at the property. In this case, you should have been welcomed into your new property with a letter from the previous owner’s current supplier addressed simply to ‘The Occupier’. Unless you notified the company, who supplied energy to your old home of your move, then this will be your new electricity supplier. If you’re still stumped, try asking the previous owner if they left forwarding details.

If you’re a tenant in a rented property, ask your landlord who supplies your electricity. Failing that, you may find the answer is already hidden in plain sight around the property. Look to see if there’s an in-home display, or IHD (if you have a smart meter), as this would have been given to the previous owner or landlord when the meter was installed, and usually features the branding of the energy supplier on its casing. Bear in mind that it’s perfectly possible to change supplier even after having an energy company install a smart meter, so don’t assume this provides a definitive answer. Look for a bill or speak to your landlord. Failing that, read on.  

Who supplies my electricity – phone numbers to know

If none of the above has worked, then you can call the Energy Networks Association to find out who your energy supplier is. You can also use its online tool if you prefer, simply type in your postcode to find your energy supplier. The UK’s electricity network is divided by region, so even if you’ve got one number stored from a previous property, if you have moved region, you will need to call a different number. Check you have the right contact for your region below:

North Scotland: 0345 026 2554

Central and South Scotland: 0330 1010 300

North East England: 0845 6013 268

North West England: 0870 7510 093

Eastern England: 0845 6015 467

Southern England: 0845 0262 554

South West England, South Wales, West & East Midlands: 0845 6015 972

South East England: 0845 6015 467

London: 0845 601 5467

Yorkshire: 0845 070 7172

Merseyside, Cheshire, North Shropshire & North Wales: 033 0101 0300

How do I find out who my gas supplier is?

The same techniques apply to finding your gas supplier as for your electricity supplier, but with one major shortcut: the Find My Supplier website can be used to perform a gas supply postcode check to reveal your supplier in just a few clicks. Simply enter your address (or postcode and house number or name), tick the appropriate boxes and click ‘Find Address’. Select your address from the list and click Yes to confirm you’re entitled to view your supply details. This will reveal both your Meter Point Reference Number (MPRN) and the names of your gas supplier and transporter (which are likely to be different). If you’re knowingly on a dual-fuel tariff, then you’ll have identified your electric supplier too.

You can also call the Meter Number Helpline on 0870 608 1524 – calls may cost 7p per minute on top of your phone company’s access charge. They will help to confirm your MPRN, which is unique to every household and are a form of identification for your gas supply, so it will also be able to tell you the current supplier.

How can I find out what type of energy plan I’m on?

After you’ve worked out who your energy supplier is, it’s time to find out what tariff you’re on and whether you’re paying too much for your electricity. Even with the Ofgem energy price cap, standard variable tariffs tend to be more expensive than other deals.

To find out what your current plan is, you have several choices: contact your electricity or gas supplier directly, check your account online or simply look for the name of the plan on your current energy bill

Who do I contact in an emergency or to report a power cut?

If you believe your problem is gas-related – for example, you can smell leaking gas or believe your supply has been interrupted due to the weather – then call 0800 111 999. This line is available 24/7 and experts will advise you on what to do next. If someone in your home has started to react to a suspected gas leak, you should call 999 immediately.

Electricity networks keep a list of priority users, comprised of vulnerable users who need extra help in the event of a power cut. If you or someone you know may be eligible and can benefit from this service, check out our guide to the Priority Services Register.

Switching energy suppliers

Once you know who your energy supplier is, there’s no reason to stick with it, so long as you are the homeowner or have your landlord’s permission to look for better deals. 

This is especially true if you have just moved house, as the previous energy supplier may have simply transferred you onto its standard plan, which is often the most expensive of its options. Energy prices change all the time, so the sooner you act, the sooner you can start saving. If you’re not on a dual fuel plan, you might find you save even more by using one supplier for both.
