Finding out who supplies your electricity and gas can feel like a puzzle, especially when you are moving home or checking a bill. However, official online tools make it straightforward to pinpoint who provides your energy. Knowing your suppliers is the first step to managing your energy, understanding your usage, and potentially finding a better deal. Understanding your energy supply is key to managing your home's bills. Fuse Energy offers clear pricing and in-app usage data to help you take control. Click [here](https://www.fuseenergy.com/app/boarding/premises) to get started. ## Finding your electricity supplier To discover your electricity supplier, the most reliable method is to use the official industry tool. This service helps you identify the company responsible for your electricity supply at any given address. ### Using the National Grid 'what's my supplier?' Tool The quickest way to find your electricity supplier is through National Grid Electricity Distribution's 'What's My Supplier?' tool. Simply enter your postcode, and the tool will provide details of your current electricity supplier. This service is free and accessible via their website. ### What to do if the tool doesn't work If the 'What's My Supplier?' tool doesn't immediately provide an answer, or if you need more information about the physical network infrastructure, you can contact your local Distribution Network Operator (DNO). DNOs are responsible for maintaining the power lines and substations in your area, but they do not handle billing or customer service. You can find your DNO using the Energy Networks Association postcode lookup tool. While DNOs primarily manage the network, they may be able to help you identify your electricity supplier or provide your Meter Point Administration Number (MPAN). ## Finding your gas supplier Similar to electricity, there's a dedicated online service to help you identify your gas supplier. ### Using the 'find my supplier' service For gas, the official UK tool is the 'Find My Supplier' service. By entering your postcode and house number or name, this service will tell you who your current gas supplier is. This is a free, industry-backed tool designed to simplify the process. ### What to do if you don't have a gas meter If your property does not have a gas meter, it means your home is not connected to the gas network. In this case, you won't have a gas supplier, and your energy needs will be met solely by electricity or other fuel sources. This is common in some new builds or properties that have converted to all-electric systems. ## Understanding your meter identifiers Beyond knowing your supplier, understanding your unique meter identifiers is key to managing your energy accounts. These numbers are specific to your property's supply points. ### What is an MPAN? An MPAN, or MPAN, is a unique reference number that identifies your electricity supply point. You'll often find it on your electricity bills. This number is essential for your supplier to accurately identify your meter and is required when switching providers. ### What is an MPRN? An MPRN, or Meter Point Reference Number, is a unique number that identifies your gas supply point. Like an MPAN, it's typically found on your gas bills and is vital for managing your gas account or switching suppliers. ### Where to find your MPAN and MPRN The easiest place to find both your MPAN and MPRN is on a recent energy bill. They are usually displayed prominently, often within a box labelled "Key Information" or "About Your Supply". If you don't have a recent bill, the online lookup tools mentioned above can help you identify your supplier, who can then provide these numbers. Alternatively, if you are a new tenant or do not have access to previous bills, you can send a clear photo of your meter to your energy supplier's support team, who can use the meter serial number to find the associated supply number. ## Common scenarios for identifying your supplier Life changes often trigger the need to find your energy supplier. Here's how to navigate common situations. ### Just moved into a new home When you move into a new home, you automatically inherit the previous occupant's energy supplier on a 'deemed contract'. To find out who these suppliers are, use the National Grid 'What's My Supplier?' tool for electricity and the 'Find My Supplier' service for gas. Make sure to take meter readings on the day you move in and contact the identified suppliers to set up your account. If you plan to switch to Fuse Energy, you do not need to contact your previous supplier separately to notify them of the move; Fuse handles the switch with your previous supplier through industry systems. Your primary responsibility will be to provide final meter readings. ### No recent bills available If you don't have access to previous bills, perhaps because you've just moved or lost paperwork, the online lookup tools are your best bet. The National Grid tool for electricity and the 'Find My Supplier' service for gas only require your postcode to get started. ### Dealing with a power cut If you experience a power cut, you should contact your DNO, not your energy supplier. DNOs are responsible for the physical network and restoring power. Your energy supplier handles your billing and customer service, but not the actual infrastructure that delivers the energy. The Energy Networks Association website provides a postcode finder to help you identify your DNO. > **Who do I contact during a power cut?** > > During a power cut, you should always contact your DNO, not your energy supplier. DNOs manage the local electricity network and are responsible for restoring power. Your energy supplier handles your billing and account, but cannot fix physical network issues. ## What to do once you know your supplier Once you've identified your electricity and gas suppliers, you have several options to manage your energy. ### Contacting your supplier The first step is to contact your identified suppliers directly. You'll need to provide your MPAN (for electricity) and MPRN (for gas), along with your meter readings and move-in date if applicable. They can then set up your account, confirm your tariff, and provide details about your energy usage. Understanding your energy usage is crucial for making informed decisions about your home's efficiency, such as considering an [air source heat pump](https://www.fuseenergy.com/blog/air-source-heat-pump-efficiency) to reduce consumption. ### Considering a switch to a new provider Knowing your current suppliers empowers you to explore your options. Many UK residents find that switching energy providers can lead to better tariffs and improved customer service. For example, understanding the [running cost of an air source heat pump](https://www.fuseenergy.com/blog/air-source-heat-pump-running-cost) can help you compare potential savings with different tariffs.
