Understanding your energy supply
Why knowing your supplier matters
Knowing your energy supplier is more than just a piece of trivia; it is fundamental to managing your household finances and ensuring you are on the best tariff. Without this information, you cannot query bills, discuss account issues, or explore options for switching to a potentially cheaper deal. It empowers you to take control of your energy costs and consumption. Understanding your energy bills and how they are calculated can also help you identify opportunities for savings.
Supplier versus network operator: what is the difference?
A common point of confusion is distinguishing between your energy supplier and your network operator. Your energy supplier is the company that sells you electricity and gas, sends your bills, and manages your account. They are who you pay.
Your Distribution Network Operator (DNO), on the other hand, owns and maintains the physical infrastructure - the cables - that deliver electricity to your home. DNOs are responsible for responding to power cuts in your area. For gas, a Gas Transporter (also known as a Gas Distribution Network or GDN) is responsible for the gas pipes and responding to gas leaks. You cannot choose your DNO or Gas Transporter; it is determined by your geographical location. For example, UK Power Networks is a DNO for parts of London and the South East, but they do not sell energy to customers. It is vital not to confuse the two, as contacting the wrong one will only delay your query.
How to find your electricity supplier
Identifying your electricity supplier relies on a unique identifier and a quick postcode lookup.
Locating your MPAN
Every electricity supply point in the UK has a unique Meter Point Administration Number (MPAN)1. This is a 21-digit number, often starting with an 'S', and is your key to unlocking your electricity supplier information. You can usually find your MPAN on a recent electricity bill.
If you do not have a bill, you will not find your MPAN on the electricity meter itself. The physical meter displays a Meter Serial Number (MSN), which is a unique identifier for the meter hardware. If you are a Fuse Energy customer and do not have a bill, you can send a clear photo of your meter to our support team, who can use the Meter Serial Number to find your supply details.
Finding your electricity supplier
To find your electricity supplier, the two consumer routes are: (1) the "What's My Supplier?" lookup at supplier.nationalgrid.co.uk, or (2) contacting your local Distribution Network Operator (DNO); find your DNO from your postcode using the Energy Networks Association's postcode tool. Using your MPAN directly is generally more reliable than searching by address.
How to find your gas supplier
Similar to electricity, finding your gas supplier involves a unique identifier and a quick postcode lookup.
Locating your MPRN
For gas, you will need your Meter Point Reference Number (MPRN)2. This is a unique number, typically between 6 and 10 digits long, that identifies your gas supply point. Like an MPAN, your MPRN can usually be found on a previous gas bill.
If you do not have a bill, you will not typically find your MPRN on the gas meter itself. The physical meter displays a Meter Serial Number (MSN). If you are a Fuse Energy customer and do not have a bill, you can send a clear photo of your meter to our support team, who can use the Meter Serial Number to find your supply details.
Using Find My Supplier
With your MPRN, you can use the Find My Supplier service (findmysupplier.energy), operated through Xoserve's national gas database, to identify your gas supplier. Enter your postcode and follow the steps to confirm your MPRN, gas supplier, and gas transporter. Using your MPRN directly is generally more reliable than searching by address.
What to do if you have just moved in
Moving into a new property can be a whirlwind, and finding your energy supplier is often low on the priority list until the first bill arrives.
Checking previous bills and tenancy agreements
The quickest way to find out who supplies your energy when you have just moved in is to check any previous energy bills left by the former occupants. These will clearly state the supplier's name. If no bills are available, your tenancy agreement (if renting) might list the current suppliers, or your landlord might have this information. If you are a Fuse Energy customer and cannot find a bill, you can send a clear photo of your meter to our support team, who can use the Meter Serial Number to find your supply details.
Contacting your landlord or letting agent
If you are renting, your landlord or letting agent is often the best first point of contact. They should be able to provide you with the details of the current electricity and gas suppliers for the property. This can save you time and effort in using the consumer look-up services.
Common questions about finding your energy supplier
What if i cannot find my MPAN or MPRN?
If you cannot locate your MPAN or MPRN on a bill, you can still find your supplier via the consumer lookup routes: National Grid's "What's My Supplier?" tool for electricity, and Find My Supplier (findmysupplier.energy) for gas. Both let you search by postcode, but using your MPAN or MPRN directly is generally more accurate if you encounter address-matching issues.
If you are struggling to find your electricity supplier, you can contact your local Distribution Network Operator (DNO). For gas, you can use the 'Find My Supplier' online tool or contact the Meter Number Helpline. Do not contact the National Gas Emergency Service (0800 111 999)3 for supplier inquiries, as this number is strictly for reporting gas leaks or the smell of gas.
What if i have a prepayment meter?
The process for finding your supplier with a prepayment meter is the same. Your MPAN and MPRN will still be on any statements or top-up cards you have. You can then use the consumer look-up services as described - "What's My Supplier?" for electricity and Find My Supplier for gas. If you are struggling, the contact details for your supplier are often on the meter itself or on your top-up key/card.
What if i only have one type of energy?
Some properties only have electricity (e.g. flats without a gas connection) or, less commonly, only gas. The process remains the same: use the relevant consumer look-up service ("What's My Supplier?" or your DNO for electricity; Find My Supplier for gas) and the corresponding identifier (MPAN for electricity, MPRN for gas). If you only have one type of energy, you simply will not have an MPAN *and* an MPRN.
Finding your energy supplier does not have to be a headache. By understanding the roles of suppliers and network operators, and knowing how to use the consumer look-up services ("What's My Supplier?" for electricity, Find My Supplier for gas) and unique identifiers like MPANs and MPRNs, you can quickly get the information you need.
