Who supplies my business phone line

Who supplies my business phone line


We make it easy for you to get prices from trusted providers, helping to ensure you get the package that’s right for your business.

If you’ve just moved in to a new business premises, it is important to make sure your phone and broadband are properly set up. Spending too long out of contact with your customers and clients can prove detrimental to your business, so it can be difficult if you encounter issues when trying to find out who supplies your business phone line.

The following is a short guide to how you can find your business phone line provider, and switch to a more suitable deal for your business.

Asking your landlord or estate agent

Perhaps the most convenient way of finding out your business phone line provider is by asking your landlord, letting agent or estate agent for the details about the utilities at your new premises. This should include the name and details of the phone and broadband provider.

Dialling 150 to find your phone line provider

Try to find the phone socket at your new business premises. If the socket has a BT logo, it’s likely that your provider is also BT. In any case, you might be able to find out who the provider is by plugging a phone into the socket and dialling 150. This should put you through to the customer services department of the relevant provider. Dialling 17070 should put you through to BT’s line test facility instead, and you may have your allocated phone number read back to you.

If you know your phone number, you might be able to use the Network Look-Up form on the AQL website to find the network operator for your line.

Installing a new phone line

If you can’t hear a dial tone, the line might have been disconnected. If you hear a dial tone but the call doesn’t get through, the line might have a block on incoming and outgoing calls. In either case, you’ll need to call the provider of your choice and ask them to install a phone line at your business. There may be a charge for installation (£110-£125 depending on the provider), although some providers may provide free installation if you purchase a phone and broadband deal with them.

Keep in mind that signing up to a long-term deal could mean you end up paying more overall, so make sure to take this into account before committing to a deal on the basis of a free installation.

Switching to a new provider

If you are unable to find out who your provider is by using the method above, it might be possible to simply switch to a new provider. If the wiring and sockets at your new premises are undamaged, switching to a new provider is likely to be free of charge as they won’t have to replace the line.

In order to switch, it's important to compare line rental prices - as well as phone and broadband packages - from different providers. This will help to ensure that you're getting a good deal from the supplier you choose.

If you need to obtain a new landline number, you’ll need to contact your current provider to cancel the supply - and contact your new provider to arrange a new service. If a new line needs to be installed at your premises, you may need to pay the cost of installation. If you choose to install more lines at your new premises, you might be charged for each line.

Before switching to a new provider, it is important to compare deals offered by all providers to help make sure you’re choosing the most cost-effective and relevant deal for your business’s needs.
