BritBox is supported on most Roku devices, though some older models may no longer be compatible.
To get started, follow these steps from Roku to download the BritBox app. If you run into issues, make sure your Roku software is up to date. Once the app is installed, open BritBox and sign in using your existing account—whether you're a current or returning subscriber.
Alternatively, you can subscribe to BritBox through The Roku Channel:
- Navigate to 'The Roku Channel' on your Roku device
- Search for 'BritBox' within The Roku Channel
- Select BritBox from the search results
- Follow the on-screen prompts to start your subscription
- This will add BritBox as a premium subscription within The Roku Channel
Note: Roku no longer supports legacy models 3600 and 4400X or any older Roku devices. Streaming the BritBox app on these older devices may not be possible.
