Verdict: Who Should Choose BT Full Fibre 300?
Choose BT Full Fibre 300 if:
✅ You are a medium to large household with multiple simultaneous internet users
✅ You value the Stay Fast Guarantee as a form of performance insurance.
✅ BT’s promotional offers, like reward cards, improve the value for you.
Consider alternatives if:
❌ You are on a very tight budget and want the absolute cheapest plan.
❌ You need the latest Wi-Fi 6 technology standard in your included router.
❌ You are in an area served by a “alt-net” provider that might offer symmetrical upload speeds for a similar or lower cost.
Final Thoughts
BT’s Full Fibre 300 is the premium SUV of broadband – offering plenty of power and space for the whole family, with a comfortable, reliable ride built on the robust Openreach network. It delivers a solid 300Mbps that easily handles multiple 4K streams and gaming, backed by the confidence of a 150Mbps Stay Fast Guarantee.
At £30.99/month, it’s competitively priced for this speed tier, though Community Fibre and other alt-nets can offer similar speeds for less in covered areas. The main compromise is the Wi-Fi 5 Smart Hub 2, which feels a generation behind rivals like EE that offer Wi-Fi 6 as standard. You’re paying for BT’s reliable infrastructure and strong UK-based support.
My take: Go for BT Full Fibre 300 if you’re a busy household that values reliability and the safety net of a speed guarantee. If you’re a gamer or have a house full of next-gen gadgets, the dated router is a real drawback—consider EE for a more future-proof setup. For pure value, always check if a cheaper alt-net serves your area first.

Is the Smart Hub 2 router any good?
