How To Watch The Big Bang Theory on Netflix or Free (2025)

Is The Big Bang Theory on Netflix? All 12 seasons of The Big Bang Theory are still available on Netflix at the time of writing, but only in select regions. The show left Netflix US, but you can stream it on other popular services, like Max and Hulu+ Live TV.

TBBT can also be streamed for free on Channel 4 in the UK. A VPN makes it possible to watch The Big Bang Theory safely from anywhere. Premium VPNs encrypt your connection and have servers worldwide, allowing safe access to seasons 1 to 12 of The Big Bang Theory. A VPN also protects your online privacy by masking your real IP address and location.

After testing 49 VPNs, I found ExpressVPN the best for watching TBBT without interruptions. It’s the fastest VPN we tested and reliably works with all major Netflix libraries, including the UK, South Korea, and Japan. Plus, you can try ExpressVPN risk-free since it offers a 30-day money-back guarantee.

1. Install a VPN

Choose a VPN with reliable speeds for HD streaming. Additionally, make sure your VPN works with Netflix, as the platform is known for blocking low-quality VPN providers. Due to its consistent speeds and compatibility with platforms that stream TBBT, I recommend ExpressVPN. It also has native Android and Apple TV apps for secure streaming on your smart TV.

You can also search for the VPN app in your device's app store

2. Connect to a Server

Open the VPN app and connect to a server for safe streaming online. ExpressVPN’s Smart Location feature automatically finds the fastest server for you. However, only certain Netflix regions, like Australia and the UK, have all 279 episodes of TBBT. ExpressVPN can also securely access 10Play in Australia and stream TBBT seasons 1 to 10 free.

There are multiple city options for many countries

3. Sign up or Log in to Netflix

Visit Netflix's website or launch the app on your preferred device. If you don't have an account yet, you'll need to sign up. Netflix offers various plans with different video qualities and numbers of simultaneous streams.

How Can I Watch The Big Bang Theory for Free?

The Big Bang Theory is available to watch for free on several platforms, including Channel 4 (UK), CTV (Canada), and 10play (Australia). However, I chose Channel 4 as the focus of this guide because it offers a user-friendly, completely free streaming experience with a straightforward registration process.

1. Install a VPN and Connect to a Server

Only VPNs with servers throughout the United Kingdom reliably work with Channel 4. Choose a UK server from your VPN’s server list to get a UK IP address. ExpressVPN covers 5 UK server locations, including London and Docklands, providing stable connections for streaming.

The London server provided the best streaming performance

2. Visit Channel 4

Go to Channel 4's website or download the All 4 app. The service is completely free but requires an account. You'll need to provide a valid UK postcode during registration.

Best VPNs to Watch The Big Bang Theory From Anywhere in 2025

ExpressVPN's Lightway protocol delivers impressive speeds for streaming TBBT uninterrupted from anywhere. This security protocol also uses less battery power, making it perfect for mobile binge-watching sessions. We got average speeds of 126.27Mbps testing UK servers. That’s enough for watching TBBT without added buffering, as only 25Mbps is required for 4K viewing.

Thanks to its MediaStreamer feature, ExpressVPN allows you to watch TBBT on any device, including older smart TVs and gaming consoles that don't normally support VPNs. This smart DNS feature doesn’t encrypt your data, so it’s faster than the regular VPN connection. For Android TV, Apple TV, and Amazon Fire Stick, you can download the VPN app from the respective app store.

The only drawback is its higher price point, which starts at $4.99/month. However, ExpressVPN frequently offers discounts up to 61%. You can test all its features risk-free with a 30-day money-back guarantee.

2. CyberGhost — Streaming-Optimized Servers for Reliable Access to TBBT

CyberGhost's streaming-optimized servers consistently work with Netflix AU, Channel 4, 10Play, and other platforms hosting TBBT. These servers are regularly monitored and updated to maintain secure access from anywhere. The streaming-optimized servers worked without issues during our tests. While a bit slower than ExpressVPN, CyberGhost is fast enough for HD streaming.

On the downside, the monthly plan comes at a higher price and provides only a short refund window. However, long-term subscriptions start at just $2.19/month and come with an extended 45-day money-back guarantee. All plans also include up to 7 device connections.

3. Private Internet Access — Unlimited Connections To Watch TBBT Safely Online on Any Device

Works With:

Netflix Disney+ APV HBO Max

Hulu BBC iPlayer Sky More

Try Private Internet Access >

PIA lets your entire household stream TBBT simultaneously with unlimited device connections. It also has a huge network of 29,650 servers, some optimized for streaming, like for the UK and Australia. During testing, we streamed different episodes on 8 devices at once, and our connection remained stable.

The app's numerous customization options might overwhelm VPN newcomers. However, PIA works efficiently out-of-the-box for streaming without any adjustments needed. You can try it risk-free using its 30-day money-back guarantee.

Our Methodology for Testing VPNs for Streaming TBBT

The primary focus of our testing was evaluating each VPN's streaming capabilities with platforms that offer The Big Bang Theory. We checked connection speeds and reliability with Netflix libraries in multiple regions and tested compatibility with Channel 4 in the UK. We also assessed device compatibility, particularly looking at smart TV support and router configurations, so you can watch TBBT on a large screen.

FAQs on Watching The Big Bang Theory

Can I watch TBBT with a free VPN?

Free VPNs lack the necessary features for streaming TBBT smoothly and securely. Only high-quality premium VPNs can access TBBT in HD from anywhere. The VPNs on this list provide risk-free trial periods through money-back guarantees, so you can try them for watching TBBT on Netflix or another platform.

Meanwhile, free VPNs are often blocked by streaming platforms, and speed restrictions prevent HD playback. Most free services also limit your data usage to just a few GB per month — not enough for binge-watching multiple episodes. More importantly, many free VPNs compromise your security by collecting and selling user data to advertisers. Some even contain malware.

How can I watch The Big Bang Theory in order?

Netflix Australia currently has the complete series available to stream in order. In the UK, Channel 4 offers all seasons for free but may rotate availability. If you're also interested in the prequel series, Young Sheldon can be watched either before or after TBBT, as it works as both an origin story and a standalone show.

Is it possible to watch Young Sheldon for free?

Young Sheldon is available free on Channel 4 in the UK. While Channel 4 requires registration, it costs nothing to create an account and start watching. Outside the UK, the show is typically behind a paywall on various streaming services. A reliable VPN can access Young Sheldon securely anywhere while protecting user data from potential threats.

Which country has The Big Bang Theory on Netflix?

The Big Bang Theory is available on Netflix in several countries, including the UK and Australia. The show was removed from Netflix US in 2024 when it moved to Max. Some European countries like Germany and Italy also carry the show. You can also watch it in Thailand, Singapore, South Africa, Hong Kong, Malaysia, the Philippines, India, and Russia.

To summarize, these are the best VPNs to watch The Big Bang Theory from anywhere...
