Full Fibre broadband is the most advanced type of internet connection available in the UK today. It uses 100% fibre-optic cables to connect the internet directly to your home, rather than relying on older copper phone lines.
Because fibre carries data as light instead of electrical signals, it's faster, more stable, and far less affected by distance or interference.
The simple answer
Full Fibre broadband uses fibre-optic cables all the way into your home, delivering faster speeds, lower latency and more reliable internet than standard broadband.
It's also known as FTTP (Fibre to the Premises).
How Full Fibre broadband actually works?
With Full Fibre:
- Fibre-optic cables run from the provider's network directly into your property
- An Optical Network Terminal (ONT) is installed inside your home
- Your router connects to the ONT using an Ethernet cable
- Data travels as light signals, not electricity
Because there's no copper involved, performance stays consistent regardless of distance.
How fast is Full Fibre broadband?
Full Fibre is designed for modern internet use.
Typical capabilities include:
- Maximum speeds now reaching 1 Gbps (1,000 Mbps)
- Upload speeds that are 10x-20x faster than standard broadband
- Stable performance even with 20+ devices connected at once
(Actual speeds depend on the package you choose, not the technology limit.)
Full Fibre vs standard broadband
The biggest difference is where fibre stops.
Standard broadband (ADSL / FTTC)
- Fibre only reaches the street cabinet
- Copper phone lines handle the final connection
- Speeds drop with distance
- More affected by noise and congestion
Full Fibre (FTTP)
- Fibre reaches inside your home
- No copper bottleneck
- Consistent speeds at peak times
- Much lower latency (important for gaming and video calls)
Why Full Fibre feels faster (even at the same Mbps)?
Even if two connections advertise the same speed:
- Full Fibre has lower latency (often under 10ms)
- Faster response times for websites and apps
- Smoother video calls and streaming
- More stable uploads for cloud backups and remote work
This is why Full Fibre feels faster in real use.
Do you still need a phone line?
No.
Full Fibre:
- Does not use a traditional phone line
- Does not rely on copper infrastructure
- Supports digital voice services if needed
Your internet and phone services become fully separate.
Who benefits most from Full Fibre?
Full Fibre is ideal for:
- Families with multiple users
- Working from home
- Streaming in HD or 4K
- Online gaming
- Smart homes and security systems
Even light users benefit from the reliability upgrade.
Is Full Fibre available everywhere?
Not yet.
In the UK:
- Availability is address-based, not postcode-based
- Rollout is expanding rapidly
- Two neighbouring homes can have different access
Always check using your full address.
The key takeaway
Full Fibre broadband uses fibre-optic cables directly to your home, offering speeds up to 1 Gbps, lower latency and a more reliable connection than standard broadband.
It's not just faster - it's future-proof.
