The Traitors UK Series 4 premieres in the UK on January 1st, 2026, with the first episode airing at 8:00 PM GMT on BBC One and streaming on BBC iPlayer shortly after the broadcast ends. For viewers in the US, that corresponds to 3:00 PM ET / 12:00 PM PT.
The new season launches with a fast-paced opening schedule, with episodes airing on consecutive days during the first week, before settling into a regular release pattern. New episodes are expected to drop multiple times per week, following the format used in previous civilian seasons, rather than a single weekly episode.
Series 4 is expected to feature 12 episodes in total, all of which will be available to stream on BBC iPlayer after their UK TV broadcast. Episodes typically appear on iPlayer immediately after airing on BBC One, making it possible to watch on demand the same day.
What’s new in Series 4 is a stronger focus on gameplay twists and strategy disruption, designed to counter the increasingly sophisticated tactics used by contestants in recent seasons. With returning viewers now highly familiar with the format, the BBC has signaled that missions, banishments, and endgame mechanics will be adjusted to keep both players and audiences guessing.
Because BBC iPlayer is geo-restricted to the UK, viewers outside the country will need an alternative way to stream The Traitors UK Series 4 without delays or regional blocks.
| Region | Streaming service | Price | Availability |
| UK | BBC iPlayer | Free (TV licence required) | Episodes air on BBC One and are available on BBC iPlayer immediately after broadcast. BBC iPlayer is geo-restricted to the UK. |
| US | Peacock | $10.99/month (Premium)$16.99/month (Premium Plus) | Previous UK seasons are available. Series 4 is expected to arrive after the UK broadcast run, not simulcast. |
| Canada | Crave | From CA$9.99/month | Earlier UK seasons are available. Series 4 availability has not been officially confirmed and may arrive later. |
| Australia | 10Play | Free (account required) | Past UK seasons have streamed for free. Series 4 availability depends on local rights and may be delayed. |
How to watch The Traitors UK Series 4 from outside the UK
The Traitors UK Series 4 streams exclusively on BBC iPlayer, which is free to watch but only available to viewers located in the UK. If you’re outside the country, the platform blocks access based on your IP address.
- Choose a VPN that works with BBC iPlayer. You’ll need a VPN that reliably provides UK IP addresses, as BBC iPlayer actively blocks many VPN servers.
- Install the VPN app on your device. Most top VPNs support computers, smartphones, tablets, Smart TVs, and streaming devices.
- Connect to a UK server. This makes it appear as if you’re accessing the internet from within the UK.
- Create or sign in to a BBC iPlayer account. BBC iPlayer accounts are free. When prompted, you’ll be asked to confirm that you have a TV licence, no licence number is required.
Why you need a VPN to watch The Traitors UK Series 4
The Traitors UK Series 4 is streamed on BBC iPlayer, a platform that is only licensed to show content within the UK. When you try to access BBC iPlayer from abroad, the service checks your IP address to determine your location and blocks playback if you’re outside the country.
A VPN (virtual private network) solves this problem by changing your virtual location. When you connect to a UK server through a VPN, your internet traffic appears to come from the UK, allowing BBC iPlayer to load normally.
What a VPN does in this case
- Assigns you a UK IP address, bypassing regional blocks
- Encrypts your internet connection, adding an extra layer of privacy
- Lets you access BBC iPlayer as if you were physically in the UK
Without a VPN, international viewers will see an error message stating that BBC iPlayer is only available in the UK.
How to watch The Traitors UK Series 4 in the US
In the United States, previous seasons of The Traitors UK are available on Peacock. However, UK seasons typically arrive after the full UK broadcast has finished, rather than airing simultaneously.
If you want to watch new episodes as they air in the UK, the most reliable option is:
- BBC iPlayer (free) using a VPN connected to the UK
This allows US viewers to stream episodes the same day they air, instead of waiting weeks for Peacock to add them.
How to watch The Traitors UK Series 4 in Australia
In Australia, earlier seasons of The Traitors UK have been available on 10Play, the free streaming service from Network 10. That said, UK seasons are usually added after a delay, and availability depends on local broadcast rights.
If Series 4 isn’t available immediately on 10Play, Australian viewers can:
- Use BBC iPlayer with a VPN to watch episodes as soon as they’re released in the UK
This is the fastest option if you want to follow the show episode by episode without spoilers.
How to watch The Traitors UK Series 4 in Canada
In Canada, The Traitors UK has previously streamed on Crave, but new seasons are not always added at the same time as the UK release.
If Series 4 doesn’t appear on Crave right away, or if you want to watch without delays:
- BBC iPlayer + a VPN gives you same-day access to every episode
This avoids waiting for the season to finish airing in the UK before it becomes available locally.
How to watch The Traitors UK Series 4 in Spain
At the time of writing, there is no dedicated Spanish streaming service confirmed to carry The Traitors UK Series 4.
For viewers in Spain, the only reliable way to watch the new season is:
- BBC iPlayer (free) with a VPN connected to the UK
This gives full access to the complete season as episodes are released, without relying on uncertain local licensing deals.
New season and cast: what’s confirmed for Series 4
The Traitors UK Series 4 continues the show’s civilian format, meaning the cast will once again be made up of everyday contestants rather than celebrities. The new season follows the same core structure as previous UK editions, with a fresh group of players competing in missions while secretly divided into Traitors and Faithfuls.
At the time of writing, the BBC has not officially announced the full cast for Series 4. Contestant details are typically revealed closer to the premiere date, often in the days or weeks leading up to the first episode airing on BBC One and BBC iPlayer. This section will be updated once the BBC confirms the lineup.
What is confirmed is the return of Claudia Winkleman, who will once again host the series and oversee the missions, round-table discussions, and banishments.
