Common questions

What is enhanced support?

We'll give you one month's FREE enhanced support when you switch your broadband to BT. Our dedicated support team will be on hand to give you advice on setting up your connection, activating accounts and configuring IP addresses etc.

Why do I need a MAC code?

If you have a MAC code from your current provider you can switch to BT without your broadband service being disrupted.

How can I get my MAC code?

To get your MAC code, find your current provider's details in the drop-down list further up the page. You can then contact them to request a code. Alternatively, order our broadband without your MAC code and we'll help you get it by setting up a 3-way phone call with your existing supplier.

Can I transfer my static IP address from another Internet service provider (ISP)?

No, but you can order a static IP address when you order your BT Business Broadband. It will be available as soon as your account is activated. We'll send you the details in your welcome letters and emails.

Can I transfer my email?

When you switch to BT you can transfer an existing domain name if you have one, or you can use the BT email address issued when you connect. If you use an email address from your current ISP, it may be worth setting up email forwarding.

Can I transfer my domain name to BT?

Yes. You can also buy new domains from BT after you've logged into your new account.

Business Broadband - things you need to know

Why do we have different prices for BT Business Broadband?

The price of BT Business Broadband depends on where you are.

We have different prices depending on which of the three 'exchange pricing areas' you're in. We do this because some areas of the country are more wired than others, so wholesale broadband is more readily available.

Our prices reflect this. We're able to offer our lowest prices in areas where there is a higher availability of wholesale broadband from different providers.

Conditions for getting BT Business Broadband

  • You need to have a router for the broadband to work.
  • BT Business Broadband is not available in all areas.
