Port your number to LineHQ
Switch without losing the number your customers already know. LineHQ ports most UK landline and business numbers over for free, then forwards them to any phone — so you keep your identity and drop the line rental.
// the short answer
Number porting moves an existing UK landline, 0800 or 03 business number to LineHQ so customers keep calling the number they already know. The number keeps working during the transfer and, once ported, forwards through LineHQ with routing, recording and voicemail-to-email instead of physical line rental.

Keep your number
Bring your existing landline, 0800 or 03 number with you — customers, letterheads and listings stay unchanged.
Free to port
We handle the transfer with the losing provider at no cost; you just tell us the number and account details.
No downtime
Your number keeps working throughout the port, and switches over to LineHQ’s forwarding on completion.
Drop the line rental
Once ported, there’s no physical line to pay for — the number lives in the cloud and rings the phones you already own.
Frequently asked questions
Can I move my landline number to VoIP?
Yes — most UK geographic landline numbers, plus 0800 and 03 numbers, can be ported to LineHQ. You keep the number and we forward it to whichever phone you choose.
How long does porting take?
Porting timescales depend on your current provider, but simple single-line ports usually complete within a couple of weeks. Your number keeps working until the switch-over.
Does it cost anything to port my number?
No — porting your number into LineHQ is free. You’ll need your account number and details from your current provider to start the request.
Will my number keep working while it’s being ported?
Yes. Your existing number carries on working normally throughout the porting process — you won’t miss calls while the transfer is arranged. It only switches over to LineHQ’s forwarding at the moment the port completes, so there’s no gap in service and no downtime for your customers.
What details do I need to port my number?
To start a port you’ll need your current account number and account details with your existing provider, plus confirmation that the number isn’t tied up in a way that blocks the move. Give LineHQ the number and those details and we handle the transfer with the losing provider at no cost to you.
Which numbers can I port to LineHQ?
Most UK geographic landline numbers, along with 0800 freephone and 03 national numbers, can be ported to LineHQ. Once moved, the number forwards to any phone you choose with full call handling — forwarding, recording and voicemail-to-email — and there’s no physical line rental to pay afterwards.
Can I port my number away from LineHQ later?
Yes. Your number is yours — if you ever move to another provider, you can port it away just as you ported it in. LineHQ has no contract and no lock-in, so you keep control of your number and can switch whenever it suits you.
