Why knowing your energy supplier matters

Knowing your energy supplier is more than just a piece of information; it is fundamental to managing your household effectively. It empowers you to understand your energy usage, rights, and options.

Managing bills and tariffs

Your energy supplier dictates the rates you pay for gas and electricity. Understanding who they are allows you to scrutinise your bills, check for accurate charges, and ensure you are on the most suitable tariff for your consumption habits. This knowledge is crucial for budgeting and avoiding unexpected costs.

Understanding your rights

Ofgem is the independent energy regulator for Great Britain, responsible for overseeing gas and electricity markets and protecting consumers. Knowing your supplier means you know who to contact if you have a complaint or need to understand your consumer rights regarding switching suppliers, billing, and complaints.

Empowering your energy choices

Identifying your energy supplier is the first step in taking control and making informed decisions about your home energy. Once you know who supplies your energy, you can compare tariffs and consider switching to a provider that better suits your needs, potentially offering more transparency and control over your energy usage. This knowledge is also vital when exploring ways to reduce your carbon footprint and energy bills, such as understanding the efficiency of an air source heat pump or analysing air source heat pump running costs.

Finding your electricity supplier

Identifying your electricity supplier typically involves finding your Meter Point Administration Number (MPAN) and, if necessary, using the "What's My Supplier?" tool.

Locating your MPAN

The electricity supply point is identified by an MPAN. This unique reference number is usually found on a recent electricity bill. It often appears in a box labelled "Supply Number" or "S Number". If you have access to a previous bill, this is the quickest way to find your MPAN.

Using "what's my supplier?"

If you cannot find a recent electricity bill, the "What's My Supplier?" tool is the correct resource to identify your electricity supplier. This online tool, operated by National Grid Electricity Distribution, allows you to enter your postcode and address to find out who supplies your electricity.

What if you've just moved in?

If you have just moved into a new property and do not have any previous bills, "What's My Supplier?" is the best starting point. Provide them with your new address, and they can identify your electricity supplier. You can then contact that supplier to set up an account or arrange a switch.

What is a DNO?

A DNO is the company responsible for maintaining the electricity network in a specific geographical area of the UK. They manage the infrastructure that delivers electricity to your home, but they do not sell you energy.

Finding your gas supplier

Identifying your gas supplier follows a similar process, focusing on your Meter Point Reference Number (MPRN) and the Find My Supplier database.

Identifying your MPRN

The gas supply point is identified by an MPRN. Like the MPAN for electricity, this unique number is typically found on a recent gas bill. Having this number makes it easier to identify your supplier.

Using find my supplier

If you have your MPRN but no bill, or if you have just moved in, gas suppliers can be identified using the Find My Supplier online tool. This tool allows you to enter your postcode to find out who your gas supplier is.

What if you don't have a bill?

Without a bill, the Find My Supplier online tool is your primary resource. You will need your full address and postcode. If the online tool does not yield results, or if you prefer, you can contact the Meter Number Helpline, details of which are available on the Find My Supplier website. They can assist in identifying your gas supplier using your address details.

What to do after finding your suppliers

Once you have identified both your electricity and gas suppliers, you are in a stronger position to manage your home energy.

Contacting your current providers

With your supplier details in hand, contact them directly. You will need to provide meter readings to ensure accurate billing from your move-in date or to reconcile your account. This is also an opportunity to confirm your tariff details and understand your contract terms. According to Ofgem, the average UK home uses around 2,500 kWh of electricity per year and 9,500 kWh of gas per year1.

Comparing tariffs and switching

Knowing your current suppliers and the tariffs you are on allows you to compare deals from other providers. Ofgem outlines consumer rights regarding switching suppliers, billing, and complaints. This comparison can help you find a more competitive rate or a supplier that offers better service or features.
