Who Is My Gas Supplier

If you've just moved house, are setting up a new tenancy, or simply haven't checked in a while, you might be unsure who supplies gas to your property. Unlike electricity, which is easy to track through online accounts or smart meters, gas supply details can sometimes be harder to pin down — especially if you've not yet received a bill or welcome pack.

Knowing who your gas supplier is matters. It affects how you set up your energy account, how you're billed, and whether you’re getting the best rate. The sooner you find out, the sooner you can take control of your energy usage, submit readings, or switch to a better tariff if needed.

Why It’s Important to Know Your Supplier

Your gas supplier is the company responsible for sending you bills and managing your gas account. When you move into a property, you're automatically placed on a "deemed contract" with the current supplier, which is often their most expensive standard rate. You remain on this tariff until you contact the supplier to set up an account or switch to a different provider.

If you don’t know who your supplier is, you could end up overpaying or missing important communications. It’s also crucial when reporting a gas emergency, as the supplier needs to coordinate with the network to ensure safety and restoration of service.

How to Find Out Who Supplies Your Gas

The quickest way to find out who supplies your gas is to use the Find My Supplier online service. This tool is managed by the UK’s gas industry and provides up-to-date information on your gas supplier and your property’s Meter Point Reference Number (MPRN). You just need to enter your address or postcode to get the details.

If you're unable to access the website or want to speak to someone directly, you can also contact the Meter Point Administration Service (MPAS) by phone. They can tell you who supplies your gas and provide your MPRN, which you’ll need to register your account with a supplier or switch provider.

What to Do After Finding Out

Once you know who your gas supplier is, it’s a good idea to contact them right away. Provide them with your name, move-in date, and an opening meter reading so they can create an accurate bill and avoid estimating your usage. This also protects you from being charged for energy used by the previous occupant.

From there, you can ask about available tariffs or begin the process of switching to a new supplier if you're not happy with the current rates. You’re under no obligation to stay with the existing supplier, and switching is usually straightforward — especially if your billing and meter information is in order.

How to Avoid Gas Supply Confusion in Future

Keeping a clear record of your utility providers, including account numbers and contact details, can prevent future confusion. If you're a landlord or property manager, make sure these details are passed to new tenants at the start of the agreement. For homeowners, storing this information with other property records makes it easier to retrieve when needed.

Some suppliers also offer apps or online portals where you can manage your account, track usage, and download your details instantly. Registering for these services can save time later, especially if you need to query a bill or arrange a switch.

If You've Just Moved In

If you've recently moved into a new home, your gas will already be connected, but you won’t necessarily know who the supplier is until you receive a letter or bill. The existing account is still tied to the property, and until you officially register, you’re likely on the supplier’s standard variable tariff, which is usually the most expensive. It’s important to act quickly to find out who the supplier is, give them a meter reading, and update the account with your name and move-in date. This ensures you're billed fairly and avoids disputes over previous usage.

Understanding the Meter Point Reference Number (MPRN)

Every property connected to the gas network has a unique identifier called a Meter Point Reference Number, or MPRN. This is not the same as your account number — it refers specifically to the gas supply at the property, not to any individual or company. The MPRN helps you and your supplier locate and verify the correct supply, especially when setting up a new account or switching providers. You can find your MPRN through the Find My Supplier website or on a previous gas bill, if available.

When a Property Has More Than One Gas Meter

In some cases, particularly in converted flats or multi-use buildings, a property may have more than one gas meter. This can cause confusion if it’s unclear which meter belongs to which unit. If you’re unsure which meter is associated with your property, your supplier or the local network operator can help identify it using the MPRN and meter serial number. Taking a photo of your meter and noting its location can also help when speaking with customer service.

What If No Supplier Is Found?

In rare cases, you might use the Find My Supplier tool and find that no supplier is listed. This can happen in properties that have been vacant for a long time, have had the meter removed, or were previously disconnected from the gas grid. If this happens, you’ll need to contact the local gas distribution network (GDN) to confirm the supply status and arrange a reconnection or new meter installation if required. They can advise whether a live supply still exists and what steps are needed to restore service safely.

Switching After You’ve Identified the Supplier

Once you've confirmed who your gas supplier is and registered with them, you're free to shop around for a better deal. Many comparison websites allow you to enter your postcode and estimated usage to find more competitive tariffs. Switching is a straightforward process and typically takes no more than a few working days. Your supply won’t be interrupted during the switch, and your new supplier will handle the process with your current one, including the final meter reading and account closure.

Contacting the Gas Network for Emergencies

While your gas supplier manages billing and tariffs, they are not responsible for the physical gas network. If you smell gas, suspect a leak, or experience a loss of supply, you should contact the National Gas Emergency Service on 0800 111 999. They operate 24/7 and will send an engineer to make the site safe. Knowing your supplier is useful for non-emergency issues, but safety concerns should always be reported directly to the emergency line.

Final Word

Finding out who your gas supplier is might seem like a minor task, but it’s an important one — especially when you're moving house or sorting out household bills. With the right tools and a quick check online, you can take control of your account, avoid being overcharged, and make sure you’re dealing with the correct provider. Whether you're staying with your current supplier or planning to switch, knowing who you're dealing with is the first step in managing your energy efficiently.
