Why you need to find your supplier

Knowing who supplies your energy is fundamental to managing your household finances and ensuring you are on the best possible tariff.

Moving home

When you move into a new property, you inherit the existing energy suppliers. Identifying them quickly allows you to set up accounts in your name, avoid estimated bills, and ensure a smooth transition.

Switching energy provider

To compare deals or switch to a new energy provider, you need to know who your current suppliers are. This information is essential for your new provider to manage the switch on your behalf.

Billing enquiries

Any questions about your energy usage, meter readings, or payments can only be addressed by your current supplier. Without their details, resolving billing issues becomes impossible.

Finding your electricity supplier

Finding your electricity supplier involves a few straightforward steps, often starting with your existing paperwork or a quick online search.

Check your bills

The quickest way to find your electricity supplier is to check a recent energy bill or statement. This document will clearly state the supplier's name and contact details.

Use the "what's My supplier?" tool

If you do not have a recent bill, the primary way to find your electricity supplier is by using the "What's My Supplier?" online tool, operated by National Grid Electricity Distribution. Simply enter your postcode on their website, and it will tell you who supplies electricity to your property.

Identify your Distribution network Operator (DNO)

Your Distribution Network Operator (DNO) is responsible for the local electricity network, including the cables and substations that deliver power to your home. If you need to report a power cut or have a network issue, you can find your DNO using the Energy Networks Association (ENA) postcode tool. However, your DNO cannot tell you who your electricity supplier is.

Finding your gas supplier

The process for finding your gas supplier is similar to electricity but uses a different national database.

Check your bills

As with electricity, your gas supplier's details will be on any recent gas bill or statement you have. This is usually the easiest method.

Use the find My supplier service

If you do not have a bill, you can use the Find My Supplier online service. This tool is run by Xoserve on behalf of the gas industry. By entering your postcode, the service will tell you who your gas supplier is and provide your Meter Point Reference Number (MPRN).

Understanding MPAN and MPRN

These unique numbers are vital for identifying your energy supply points and are often requested when dealing with suppliers or switching.

What is an MPAN?

The Meter Point Administration Number (MPAN) is a unique 21-digit reference number that identifies your electricity supply point. It is often displayed within a box on your electricity bill, sometimes referred to as a "Supply Number".

What is an MPRN?

The MPRN is a unique number that identifies your gas supply point. This number helps gas transporters and suppliers locate your specific gas meter.

Why these numbers matter

These numbers are like a postcode for your energy supply. They allow energy companies to accurately identify your meter and supply point, which is crucial for billing, meter readings, and switching suppliers, especially with a smart meter.

Just moved in? here's how to find your supplier

Moving into a new home can be hectic, but identifying your energy suppliers should be a priority to avoid issues.

Contact your landlord or letting agent

If you have just moved into a rented property, your landlord or letting agent should be able to provide you with the details of the previous occupants' energy suppliers.

Check for previous bills

Look for any old energy bills or statements left by the previous occupants. These will contain the supplier's information.

Use the official lookups

If you cannot get the information through the above methods, use the official online lookup tools:

  • For electricity, use the "What's My Supplier?" tool.
  • For gas, use the Find My Supplier service.

What to do after finding your supplier

Once you know who supplies your gas and electricity, you can take control of your energy arrangements.

Review your current tariff

Check the details of your current tariff, including unit rates, standing charges, and contract end dates. This will help you understand what you are paying and if you are on a fixed or variable rate, and potentially how to achieve energy bill savings.

Consider switching providers

With your current supplier details and MPAN/MPRN, you are well-equipped to compare energy deals and consider switching providers. Many people find better value by exploring the market.
