No. Emergency calls are always free, regardless of your plan or account balance.
You will never be charged for dialling emergency services. This applies to all emergency numbers, including 999 and 112.
This is a legal requirement across all phone providers in the UK, VoIP included.
A few things worth knowing about emergency calls on VoIP:
You won't be charged for any emergency call. This may appear as a billed item, however, the amount should always be credited to your balance.
VoIP emergency calls require an active internet connection. If your internet goes down, you won't be able to reach emergency services through your VoIP line. Keep a mobile phone nearby as a backup.
Make sure your registered address is up to date in your account settings. Emergency services use this to locate you, since VoIP calls can't be traced the same way traditional landline calls can.
If you're using your VoIP line abroad, emergency calling availability may vary depending on your provider and local regulations.
If you spot an unexpected charge that looks like it's tied to an emergency call, contact our support team and we'll sort it out for you.
