BT Full Fibre 900 is currently the fastest broadband plan available from BT for home use. It offers average download speeds of 910Mbps and uploads of up to 110Mbps over the Openreach full fibre network (FTTP). That makes it one of the fastest mass-market broadband options in the UK, competing directly with Virgin Media Gig1, Vodafone Full Fibre 910 and other CityFibre-powered gigabit plans.
The key difference is that BT Full Fibre 900 uses a 100% fibre connection from the exchange to your home. This avoids the copper cables still used by some other networks and helps reduce latency, improve reliability, and maintain consistent speeds throughout the day—even during peak hours.

BT Full Fibre 900 Deals
BT Full Fibre 900 is available as both broadband-only and broadband-and-phone options. The broadband-and-phone deal costs £5 more per month.
The broadband-only plan is suited to homes that don’t need a landline, while the broadband and phone version includes BT’s digital voice service, which uses the full fibre connection to make and receive calls.
BT broadband and phone customers can choose from a few different call plans.
The Pay As You Go option is the default, where you only pay for the calls you make. Charges apply per minute to UK landlines and mobiles.
If you make more regular calls, you can upgrade to the 500 or 700 Minutes plan. These give you a monthly allowance of inclusive minutes to UK landlines and mobiles, with standard rates applying after the limit is used.
For heavy users, the Unlimited Minutes plan includes unlimited calls to UK landlines and mobiles at any time, with no cap on duration.
Both broadband only and phone bundles come on a 24-month contract with no setup fee and include the Smart Hub 2 router, BT Virus Protect, and access to over five million EE Wi-Fi hotspots. Extras like BT TV or Complete Wi-Fi can be added if needed.
BT Full Fibre 900 Speeds
BT advertises average download speeds of 910Mbps and average uploads of 110Mbps. These figures reflect typical peak-time performance across BT’s Openreach-powered FTTP network.
What you actually get will vary slightly depending on your device and home setup. The guaranteed minimum speed to the hub is lower and varies by location, but BT lets you cancel without penalty if the service consistently fails to meet that minimum for 30 days.
In practice, wired devices connected to the Smart Hub 2 using a gigabit Ethernet cable usually see download speeds of 850–920Mbps and upload speeds between 100–110Mbps. That puts it very close to the advertised figures.
Wi-Fi performance depends heavily on your device’s age, location in the house, and how many other devices are active. A newer laptop with Wi-Fi 6 in the same room as the hub may see speeds around 600–750Mbps. Smartphones often record 400–600Mbps. In rooms further from the hub, it can drop to 200–350Mbps unless you add mesh discs.
Upload Speed
The 110Mbps upload speed is a noticeable upgrade from BT’s lower-tier plans. For example, Full Fibre 500 only offers 73Mbps uploads. Moving to Full Fibre 900 gives a sizeable boost to anyone uploading large files, using video conferencing, or running home security cameras that stream to the cloud.
While not symmetrical like CityFibre or Hyperoptic plans, the 110Mbps upload speed is still enough to handle most heavy usage cases. It’s faster than Virgin Media Gig1’s 104Mbps average, and easily supports multiple simultaneous uploads, cloud backups, and live streams.
Speed Tests and User Feedback
Customer feedback across forums such as ThinkBroadband, Reddit, and ISP review sites shows that BT Full Fibre 900 consistently delivers close to the advertised speeds—especially over Ethernet.
Many users report download speeds above 880Mbps on wired connections, with uploads frequently in the 100–110Mbps range. Wireless speeds vary depending on the device and router placement. For best results, a wired test using gigabit Ethernet is recommended.
Unlike Virgin Media, BT users report fewer issues with evening slowdowns. This is largely due to the FTTP network design, which avoids local cabinet congestion and performs better during peak demand. Reports of buffering or throttling are rare on BT’s Full Fibre 900 tier.
However, some feedback mentions that older devices struggle to hit high speeds over Wi-Fi. Others point out that the Smart Hub 2 lacks newer Wi-Fi 6 standards, meaning maximum performance is sometimes only available via cable or custom routers.
Value for Money
BT Full Fibre 900 isn’t cheap, but it delivers top-end performance. At £37.99 per month, it’s slightly less expensive than Virgin Media Gig1 and a bit more than BT’s Full Fibre 500. The upgrade brings faster uploads and better headroom for busy homes with many devices.
In terms of cost per megabit, it actually offers better value than some slower plans. You’re paying a bit more but getting a lot more in terms of bandwidth. This matters if your household is streaming in 4K, running multiple devices, gaming online, and doing video calls all at once.
The downside is the pre-scheduled price rises. From March 2026, your monthly price goes up to £41.99, then again to £45.99 from March 2027. These increases are baked into the contract, so you need to factor them in when comparing deals.
Unlike some altnets, BT does not offer symmetrical speeds or guarantee Wi-Fi in every room unless you pay extra for the Complete Wi-Fi service.
Customer Service and Support
Support for BT Full Fibre 900 is handled through the same channels as BT’s other broadband plans. You get access to phone support, web chat, and the MyBT app to manage your account and check service status.
BT also sells an optional Complete Wi-Fi add-on, which provides mesh discs to boost coverage throughout the home. This comes with a performance guarantee—if BT can’t deliver at least 10Mbps in every room after installing the mesh system, you can claim a refund on the add-on.
Ofcom’s latest customer satisfaction data places BT around the middle of the pack for broadband complaints. It performs better than Virgin Media and TalkTalk in most areas, but not as well as Sky for customer satisfaction and complaint handling.
The installation process is straightforward for most homes. If you already have FTTP installed, activation is usually quick. If not, BT may need to send engineers to run a fibre cable from the street to your home.
Router – BT Smart Hub 2
BT Full Fibre 900 includes the Smart Hub 2. It’s the same router used on all of BT’s fibre packages and offers reliable wired performance. However, it’s not equipped with Wi-Fi 6 or 6E, which is starting to become standard among newer routers.
Key features include:
- Four gigabit Ethernet ports
- Dual-band wireless (2.4GHz and 5GHz)
- WPA2 encryption
- Smart channel optimisation to reduce Wi-Fi interference
- Support for BT’s Complete Wi-Fi mesh system
Although the Smart Hub 2 can comfortably handle gigabit speeds on wired connections, some users with newer devices prefer to upgrade to a third-party Wi-Fi 6 router to get the best wireless performance. BT doesn’t currently offer a Wi-Fi 6 model as standard.
Who Should Choose BT Full Fibre 900?
BT Full Fibre 900 is a good option for households that need fast, consistent speeds across many devices. It’s best suited for:
- Homes with 4 or more users streaming, gaming, and working at the same time
- Power users who rely on fast uploads for video calls, cloud storage or content creation
- Households with 15+ connected devices, including smart TVs, cameras, laptops, and phones
- Families that want a future-proof broadband plan that can handle upgrades in tech and streaming quality
The upload speed makes it particularly useful for remote workers and anyone backing up data to the cloud or uploading large files.
Who Should Go for Alternatives?
BT Full Fibre 900 may not be necessary for everyone. You might want to consider other options if:
- You only use broadband for casual streaming, browsing, and light gaming. BT Full Fibre 300 or 500 is cheaper and still fast.
- You want symmetrical speeds. Providers like Hyperoptic, Community Fibre or Vodafone over CityFibre offer 1Gbps uploads and downloads.
- You live outside of BT’s FTTP rollout area. In that case, Virgin Media Gig1 or an altnet may be your only gigabit option.
If your usage isn’t demanding, stepping down to a lower BT plan can save a meaningful amount over a 24-month contract.
Our Verdict
BT Full Fibre 900 is one of the fastest broadband options available nationwide through the Openreach network. It combines near-gigabit download speeds with 110Mbps uploads and delivers a consistently reliable connection for large households and heavy usage.
It may not be the cheapest gigabit plan available, and the router is starting to show its age compared to some competitors. But the full FTTP connection and strong peak-time performance make it a worthwhile option for users who need bandwidth without compromise.
It’s not symmetrical, and the price will rise twice during your contract—but even with those increases, BT Full Fibre 900 remains a top-tier broadband option for those who value consistency, low latency, and full Openreach compatibility.
Alternative Plans from Other Providers
