- Email addresses provided by your broadband supplier are usually tied to the service, so switching provider can mean losing the address.
- Ofcom has recognised the loss of a provider email address as a barrier that discourages some customers from switching.
- Some providers let you keep the email for a fee or a limited period; others withdraw it after you leave.
- Migrating to an independent free email account before you switch removes the lock-in entirely.
One quiet reason households stay with a broadband provider they would otherwise leave is the email address that came with the service. If your address ends in your provider's domain, switching can mean losing it, along with every account and contact tied to it. The fix is to stop depending on a provider-linked address before you ever need to switch.
Why provider email is lost on switching
An email address issued by your broadband supplier is generally a feature of the service, not a standalone product. When the service ends, the mailbox can be closed. Some providers offer to keep your address active for a monthly fee or for a grace period; others simply withdraw access. Either way, you do not own the address the way you own an independent webmail account.
Why this matters more than it seems
Ofcom has identified email lock-in as a genuine barrier to switching. The address is often used to log in to banking, shopping, government services and social accounts, and to receive password resets. The prospect of losing it, and of missing important messages, is enough to keep people paying more than they need to. Recognising that as a sunk-cost trap is the first step to escaping it.
How to migrate before you switch
Set up a free, independent email account with a major webmail provider, one that is not tied to any broadband supplier. Then work through your accounts methodically: update the contact address on banking, utilities, shopping, social media and government logins, and set up forwarding from the old address while it still works so nothing slips through. Export and import your contacts so your address book moves with you.
A migration checklist
| Step | Action |
|---|---|
| 1 | Create a free independent webmail account |
| 2 | Set up forwarding from your provider address while it still works |
| 3 | Update banking, government and shopping logins to the new address |
| 4 | Export and import your contacts |
| 5 | Update newsletters, subscriptions and password-reset addresses |
| 6 | Only then proceed with the broadband switch |
The result: a switch with nothing holding you back
Once your important accounts use an independent address, losing the provider email costs you nothing, and you can choose broadband purely on price and service. Doing this once, in advance, permanently removes one of the most effective forms of provider lock-in.
Frequently asked questions
Do I lose my email address when I switch broadband?
Usually yes, if the address is tied to your broadband provider's domain. The mailbox is generally a feature of the service, so when the service ends the address can be closed unless the provider offers to keep it active.
Can I keep my BT or Sky email after switching?
Some providers offer to keep a provider email address active for a fee or a limited period after you leave, while others withdraw it. Check your specific provider's policy, but the safer approach is to migrate to an independent address first.
How do I transfer my contacts away from an ISP email?
Export your contacts from the provider mailbox and import them into a new independent webmail account. Set up forwarding from the old address while it still works so you do not miss messages during the transition.
What is the best alternative to an ISP email address?
A free, independent webmail account from a major provider that is not tied to any broadband supplier. Because it is not linked to your internet service, you keep it no matter which broadband provider you use.
How does an ISP email address trap customers?
Because the address is used to log in to banks, shops and government services and to receive password resets, the fear of losing it discourages switching. Ofcom has recognised this email lock-in as a real barrier to changing provider.
