Who supplies my energy?

Knowing who supplies your energy is crucial for managing your household bills effectively. Whether you are moving into a new property, looking to switch tariffs, or simply need to resolve a billing query, identifying your supplier is the first step. It also ensures you know who to contact in the event of a power cut or gas emergency.

Why you need to know your energy supplier

Understanding who your energy supplier is underpins several key aspects of managing your home's energy. Without this information, you could be paying more than necessary or face delays in resolving issues.

Moving house

When you move into a new property, you automatically inherit the previous occupant's energy supplier on what is known as a "deemed contract". These tariffs are often among the most expensive on the market, so identifying your supplier quickly allows you to set up an account in your name and explore better deals.

Switching tariffs

To compare energy deals and switch to a more competitive tariff, you need to know your current supplier. Comparison sites and new suppliers will ask for this information to facilitate the switching process. Exploring options like an air source heat pump running cost analysis can also help you understand potential long-term savings.

Billing enquiries

If you have questions about your energy bills, need to update your payment details, or dispute a charge, you must contact your specific energy supplier. They handle all aspects of your billing and customer service.

Power cuts and emergencies

While your energy supplier handles your billing, a different company, your Distribution Network Operator (DNO), is responsible for the physical infrastructure that delivers energy to your home and fixes power cuts. For a power cut, you should always contact your DNO directly by calling 105, the free national power cut emergency number in Great Britain. This number connects you to your local electricity network operator, not your energy supplier.

Finding your electricity supplier

Identifying your electricity supplier is a clear process using a national online tool.

Using the National Grid "what's my supplier?" Tool

The official online tool for finding your electricity supplier in the UK is National Grid's "What's My Supplier?". You can use this service by entering your postcode and house number or name. The tool will then display your current electricity supplier and your Meter Point Administration Number (MPAN).

Contacting your distribution network operator (DNO)

If the online tool is inconclusive, or if you need to identify your network operator rather than your supplier (for instance, during a power cut), you can contact your local DNO. DNOs are responsible for the local energy infrastructure, such as cables, poles, and substations. They are distinct from energy suppliers, who handle your billing and energy supply contract. You can find your DNO using the Energy Networks Association (ENA) postcode lookup tool. Alternatively, you can call 105, which will connect you directly to your local electricity DNO.

Understanding your MPAN

Your electricity supply has a unique 21-digit MPAN. This number identifies your electricity supply point and is crucial for any interactions with your supplier or when switching. You can usually find your MPAN on a recent electricity bill.

Finding your gas supplier

Similar to electricity, there is a dedicated online service for finding your gas supplier.

Using the "find my supplier" tool

The official online tool for finding your gas supplier in the UK is "Find My Supplier". By entering your postcode, the tool will provide you with details of your gas supplier and your Meter Point Reference Number (MPRN). This service is run on behalf of the gas industry.

Understanding your MPRN

Your gas supply has a unique MPRN. This number identifies your gas supply point and is essential for managing your gas account or switching suppliers. You can typically find your MPRN on a gas bill.

What to do if you have just moved in

Moving into a new home can be hectic, but sorting out your energy supply early can save you money and hassle.

Initial steps

Upon moving in, your property will be on a "deemed contract" with the existing supplier. It is important to identify these suppliers as soon as possible, as deemed rates are often uncompetitive. Use the "What's My Supplier?" tool for electricity and "Find My Supplier" for gas.

Taking meter readings

As soon as you move in, take clear photos of your electricity and gas meters, noting the date and time. These initial readings are vital for ensuring you are only charged for the energy you use from your move-in date. Provide these readings to your identified suppliers when you contact them to set up your account.

Setting up your account

Once you have identified your suppliers and have your initial meter readings, contact them to set up a new account in your name. They will ask for your move-in date and meter readings. At this point, you can also enquire about their available tariffs and consider if you want to switch to a different deal. Understanding air source heat pump efficiency could also be part of exploring energy-saving options for your new home.

What if you cannot find your supplier?

Sometimes, the online tools might not yield immediate results. Do not worry; there are other avenues to explore.

Checking old bills or tenancy agreements

If available, look through any old energy bills or tenancy agreements left at the property. These documents often contain the supplier's name, account numbers, and MPAN/MPRN details.

Contacting previous occupants

If you have a way to contact the previous occupants, they may be able to provide details of their energy suppliers. This can be a quick way to get the information you need.

Seeking advice from Citizens Advice

If you have exhausted other options, Citizens Advice offers free, independent advice on energy problems. They can help you understand your rights and guide you through the process of identifying your supplier.
