What is BT Full Fibre 300?

BT Full Fibre 300 is one of BT’s advanced full fibre packages. Offered at £31.99 per month on a 24-month contract, it boasts a significantly faster speed than BT Fibre Essential. With BT Full Fibre 300, users can expect an average download speed of 300 Mbps and a Stay Fast Guarantee of 150 Mbps, ensuring that speeds remain consistent even during peak hours between 8-10 pm (more details can be found on our Stay Fast Guarantee page).

The package also offers an upload speed of 49 Mbps, making it suitable for medium to large households with multiple users.
Before finalising your choice, it’s beneficial to compare the offerings from different providers (e.g., BT vs. Sky) and explore other BT broadband packages. For example, BT has recently revised the pricing for many of its packages, making the Full Fibre 500 (500 Mbps⬇) and Full Fibre 900 (900 Mbps⬇) options even more attractive. We recommend considering these options alongside the Full Fibre 300 package. Additionally, our comprehensive BT full fibre review page provides insights that can help you make an informed decision.

The Full Fibre 300 package utilises a fibre-to-the-premises (FTTP) connection, delivering an impressively low latency connection averaging 7 ms. Such low latency ensures minimal speed reduction, resulting in a noticeably faster and more stable connection for web browsing, gaming, and video conferencing on platforms like Teams and Zoom. Especially when compared to the higher latency often seen with ADSL connections.

The Full Fibre 300 broadband package allows users to enjoy rapid downloads, seamless HD streaming on multiple devices, and swift data transfers. This package is perfect for households with 3-5 members, gaming enthusiasts, streaming aficionados, or professionals working remotely. Given the upload speed of 49 Mbps, it’s more than sufficient for multiple simultaneous video calls. For instance, a typical Teams or Zoom call requires only 2-3 megabytes per second for uploading. Even if multiple household members are on video calls simultaneously, the connection should remain stable and smooth.

What are the Benefits of BT Full Fibre 300?

BT Full Fibre 300 is rapidly gaining traction among broadband users, and it’s easy to see why. This package is not just about impressive speeds but also the comprehensive benefits it brings to the table. Here’s a closer look at the standout features of the BT Full Fibre 300 package:

1. Superior Internet Speeds

Offering a whopping download speed of 300 Mbps, BT Full Fibre 300 ensures that users can indulge in ultra-HD streaming, instantaneous downloads, and lag-free browsing. Whether it’s streaming the latest blockbuster in 4K or downloading extensive datasets, the experience is bound to be swift and smooth.

3. Value for Money

Priced at £32.99 for the standalone broadband package, BT Full Fibre 300 offers an unbeatable value proposition. The cost per Mbps is competitive, ensuring users get top-tier internet speeds without straining their budgets.

4. Exceptionally Low Latency

With an average latency of around 7 ms, online gamers and professionals can rejoice. This ultra-low latency ensures that online games are lag-free and that video conferencing tools like Zoom and Teams offer crystal-clear quality without delays.

5. BT Smart Hub 2

The BT Full Fibre 300 package is complemented by the BT Smart Hub 2, known for its robust WiFi capabilities. Whether you have a small apartment or a sprawling house, the Smart Hub 2 ensures consistent WiFi coverage, thanks to features like advanced interference filters and intelligent channel selection.

6. No Landline Constraints

A significant advantage of many BT packages, including the Full Fibre 300, is the absence of a mandatory landline. This means users can opt for a broadband-only plan, ensuring they only pay for services they truly need.

7. BT’s Unmatched Network Reliability

Choosing BT means tapping into one of the UK’s most extensive and reliable broadband networks. With decades of experience and a commitment to continuous infrastructure upgrades, BT ensures that users get a seamless and dependable broadband experience.

Customer Reviews


When evaluating BT Full Fibre 300, it’s essential to consider various sources of feedback and data. According to OfCom data, BT boasts a slightly above-average customer satisfaction rate of 85% for its broadband offerings. However, a glance at BT’s Trustpilot page paints a different picture. The overall company rating stands at 1.5 out of 5 stars, based on a total of 14,609 reviews. Should these reviews deter potential customers? We believe context is crucial. BT serves approximately 9.4 million broadband users, holding the UK’s largest market share at 33.6%. The reviews represent a mere 0.15% of all BT’s clientele and an even tinier fraction of BT broadband users.

While it’s essential to consider genuine concerns from reviewers, it shouldn’t be the sole deciding factor. Being well-informed and prepared can ensure a satisfactory experience. Here are some recommendations before making a purchase:

  1. Assess Your Needs: Ensure that the service upgrade aligns with your requirements for the upcoming 24 months.
  2. Analyse Pricing Trends: Stay cautious of temporary discounts and meticulously compare prices and packages across various providers.
  3. Anticipate Service Disruptions: Service interruptions can happen with any provider. Having a backup plan, like a mobile data package or a local workspace, can be beneficial during such times.
  4. Familiarize Yourself with Contract Details: Thoroughly understand the terms, conditions, and associated costs. Always verify charges and fees before finalizing your purchase.

How Many Devices Can Full Fibre 300 Handle?

Before delving into the specifics of BT’s Full Fibre 300 package, it’s essential to understand the distinction between Mbps and Megabytes per second. This differentiation is pivotal as it profoundly influences the streaming capabilities at different resolutions.

Mbps denotes Megabits per second, a metric for data transfer speed. Conversely, Megabytes (MB) represent a unit of digital information storage. To transition from Mbps to MB/s (Megabytes per second), you must divide by 8 since there are 8 bits in a byte.

Given that your BT Smart Hub 2 (or its equivalent) is optimally configured, the Full Fibre 300 connection from BT offers the following streaming capabilities based on YouTube’s recommendations:

  1. 4K UHD (20 Mbps): With a requirement of 20 Mbps for 4K UHD streaming, the Full Fibre 300 package can support streaming on up to 15 devices simultaneously.
  2. HD 1080p (5 Mbps): For Full HD 1080p streaming, which requires 5 Mbps, you can stream on up to 60 devices concurrently.
  3. HD 720p (2.5 Mbps): At HD 720p resolution, which demands 2.5 Mbps, the package allows for streaming on 120 devices at the same time.
  4. SD 480p (1.1 Mbps): For SD 480p streaming, you can support up to 272 devices concurrently.
  5. SD 360p (0.7 Mbps): With the lowest requirement of 0.7 Mbps for SD 360p, the Full Fibre 300 connection can facilitate streaming on over 428 devices simultaneously.

These figures highlight the robust streaming potential of the BT Full Fibre 300 package, ensuring a smooth and buffer-free experience for users across various video resolutions.
