BT Full Fibre 100 Review: Is the UK’s Broadband Veteran Still Worth Your Money?
Choosing broadband in 2026 feels like picking a streaming service – endless options, hidden fees, and that nagging fear you’re overpaying. BT, the UK’s telecoms granddad, now battles flashy newcomers like Hyperoptic and Community Fibre.
But does their Full Fibre 100 plan still cut it? We’ve stress tested the speeds, router, and pricing to help you decide if BT deserves your cash, or if rivals like Vodafone or Plusnet offer better bang for buck.
BT Broadband
Fast Reliable Nationwide Broadband
✅ Guaranteed minimum speeds up to 900 Mbps.
✅ Highly rated BT Smart Hub routers
✅ Great customer support with quick response rates.
Key Takeaways
- ⚡ 150Mbps actual speeds (despite the “100” branding)
- 📶 Outdated Wi-Fi 5 router – rivals offer Wi-Fi 6
- 💷 Price: check BT.com – BT’s deals page didn’t list Full Fibre 100 on 1 November 2026 (Full Fibre 150 was £30.99)
- 📝 24-month contract – no landline included
- 🏆 Better alternatives exist unless BT has exclusive deals
Speed & Performance
Let’s cut through the confusion: BT Full Fibre 100 actually delivers 150Mbps download speeds (30Mbps upload).
What Can You Do with 150Mbps?
Here’s how BT stacks up against common online activities:
Stream 4K/UHD content on multiple devices simultaneously
Download time with 150 Mbps connection
Number of concurrent HD streams for family viewing
Upload time to cloud storage
High-quality video calls without disruptions
Support for connected cameras, speakers, and smart appliances
Smartphones, tablets, computers using internet simultaneously
Time to download software updates or media files
Stream gameplay or videos to platforms like Twitch/YouTube
Multiple people working remotely with video calls and file sharing
Real-world tests show 138-147Mbps speeds during peak hours. Works for most homes, but heavy uploaders (e.g., video editors) should consider faster options like Virgin Media’s 1Gbps plan.

Customer Service
BT’s strong point:
- ☎️ 8/10 Trustpilot ratings

- UK-based support (test call resolved in 9 mins)
But EE/Plusnet use the same support team – no reason to pay BT’s premium.
