If you’re a BT broadband customer or considering switching, you’ve likely come across two popular options: BT Smart Hub vs Smart Hub 2. At first glance, they might look similar—both designed to deliver fast Wi-Fi, stable connections, and easy setup.
But dig a little deeper, and you’ll find that BT’s second-generation hub comes with significant improvements in speed, security, coverage, and smart home integration.
In this article, we’ll break down the difference between BT Smart Hub 1 and 2, compare their key specifications, and help you decide which one best suits your home or business setup.
What Is the BT Smart Hub?
The BT Smart Hub, also known as Smart Hub 1, was a major leap forward when it was first introduced. It replaced the older Home Hub series, bringing faster Wi-Fi and stronger connectivity.
Key Features of BT Smart Hub (Smart Hub 1):
-
Dual-band Wi-Fi (2.4GHz and 5GHz) for flexible connectivity
-
Seven internal antennas for wide coverage
-
Smart channel selection to reduce interference
-
User-friendly setup via BT Smart Hub Manager
For most UK homes, the Smart Hub provided a reliable internet experience—ideal for streaming, browsing, and casual smart device use. However, as households added more smart tech, the need for greater capacity and smarter management became clear.
What Is the BT Smart Hub 2?
The BT Smart Hub 2 is BT’s upgraded router, built to support today’s data-heavy homes and emerging smart home ecosystems. It’s faster, smarter, and more secure—designed with future-proof connectivity in mind.
Core Improvements in Smart Hub 2:
-
Wi-Fi 5 (802.11ac) support for higher speeds and stability
-
WPA3 encryption for enhanced security
-
Dual-band Wi-Fi with better range optimization
-
Smart network management for multiple connected devices
-
Built-in DECT support for BT Digital Voice (landline over broadband)
In short, if Smart Hub 1 was about improving connectivity, Smart Hub 2 is about managing smart lifestyles—perfect for homes equipped with devices like Simpled smart locks, digital door viewers, and wireless security systems.

1. Connectivity and Performance
Speed & Stability
The BT Smart Hub 2 delivers faster Wi-Fi performance through improved internal hardware and refined antenna design.
If your household uses 4K streaming, multiple connected smart locks, or Wi-Fi cameras, Smart Hub 2 handles the load more efficiently.
Real-world tests show that Smart Hub 2 maintains signal quality across larger UK homes—particularly useful if your setup includes BLE-based smart devices, such as Simpled smart locks connected via Wi-Fi bridges.
Pro Tip:
If you live in a multi-storey home, pairing Smart Hub 2 with BT Complete Wi-Fi discs ensures smooth coverage and zero dead zones.
2. Security Enhancements
Security is one of the biggest differences between Smart Hub and Smart Hub 2.
Smart Hub 1 offered WPA2 protection, which is now considered outdated. Smart Hub 2 upgrades this to WPA3, giving stronger encryption and protection against cyber threats—especially important when you’re running IoT or smart lock systems.
Why It Matters:
-
WPA3 reduces risks of password cracking.
-
Safer for smart home devices like Simpled digital locks or doorbell cameras, which rely on constant Wi-Fi connectivity.
-
Protects personal data shared between your devices and the internet.
3. Smart Home Compatibility
The difference between Smart Hub and Smart Hub 2 is most noticeable in how they handle smart ecosystems.
Smart Hub 2 is compatible with BT’s Complete Wi-Fi system and connects smoothly with popular voice assistants like Amazon Alexa and Google Assistant. This makes it ideal for households running smart lighting, thermostats, and locks.
🏠 Example: When paired with a Simpled SS Slim Smart Lock, homeowners can automate actions like locking doors at night or receiving access alerts directly through their Wi-Fi hub.
4. Design and User Interface
Smart Hub 2 introduces a cleaner design—a matte grey body with vertical orientation, offering better airflow and a smaller footprint.
Interface Upgrade:
The new hub includes a modern dashboard that allows users to:
-
View connected devices
-
Adjust Wi-Fi channels
-
Manage parental controls
-
Run diagnostics easily
It’s designed to be more intuitive, making troubleshooting or adjustments much faster—perfect for homeowners who want simplicity without compromising power.
5. Voice and Broadband Integration
Another big leap in Smart Hub 2 is BT Digital Voice—a feature not available in Smart Hub 1.
It replaces traditional phone lines with a VoIP (Voice over Internet Protocol) system, meaning you can make calls through your broadband connection.
This makes Smart Hub 2 a more future-proof investment, aligning with the UK’s transition to digital phone services by 2025.
6. Future-Proofing & Longevity
If you’re wondering “Is Smart Hub 2 better than Smart Hub 1?”, the answer is yes—especially when considering long-term usability.
Smart Hub 2 is designed for future compatibility with new devices and protocols. Firmware updates ensure ongoing performance and security improvements.
For smart home enthusiasts or tech-forward UK families, Smart Hub 2 offers a stable foundation for integrating smart locks, security sensors, and home automation systems.
Common Mistakes When Upgrading
Many users switch hubs without optimizing their setup. Avoid these common pitfalls:
-
Skipping Firmware Updates: Always update to the latest version for peak performance.
-
Overloading Devices: Disconnect unused smart devices to free bandwidth.
-
Ignoring Placement: Position your hub centrally for optimal coverage.
-
Mixing Network Names: Rename your new Wi-Fi to avoid confusion with the old hub.
Which Hub Should You Choose?
| Choose BT Smart Hub 1 if: | Choose BT Smart Hub 2 if: |
|---|---|
| You have fewer than 5 devices | You have multiple smart home devices |
| You live in a small flat | You live in a large house |
| You’re on a tight budget | You want future-ready security and performance |
