Ultrafast broadband, broken down

Ultrafast broadband is broadband with download speeds typically starting from around 300 Mbps and above. It's designed for households that stream, game, work from home and connect lots of devices at the same time.

In simple terms, ultrafast broadband gives you more room to do more online without worrying about your connection struggling to keep up.

Many ultrafast broadband services are delivered using full fibre technology, also known as Fibre to the Premises (FTTP). This means fibre optic cables run directly to your property, helping deliver more consistent, faster performance than older broadband networks.

At TalkTalk, our ultrafast broadband range includes speeds up to 900 Mbps, giving you the flexibility to pick a package that matches your online habits.

Fibre broadband made simple

Not all fibre broadband is the same

Some older fibre connections use a combination of fibre and copper cables – AKA part-fibre. Newer full fibre connections use fibre to the property (FTTP) or full fibre, unlocking a more dependable online experience – ultrafast broadband falls under this.

If you're comparing broadband deals and noticing terms like FTTP, gigabit broadband and ultrafast fibre broadband, they're often talking about services capable of delivering significantly higher speeds than traditional part-fibre connections.

How ultrafast broadband works

Most modern ultrafast broadband services are delivered using Fibre to the Premises (FTTP).

Fibre to the Cabinet (FTTC)

With older part-fibre services, fibre cables run to a street cabinet before copper cables complete the journey to your property.

Full Fibre (FTTP)

With Full Fibre, fibre optic cables run directly to your home, helping deliver faster speeds and more consistent performance.

Gigabit broadband explained

Gigabit broadband is capable of delivering speeds close to or above 1 Gbps (1,000 Mbps). It's one of the fastest broadband technologies currently available to UK households.

Is ultrafast broadband right for you?

Not everyone needs the fastest available package. The best broadband depends on how your home uses the internet.

Busy households

Great for when multiple family members stream, browse and video call at the same time.

Gamers

Great for larger downloads, frequent updates and households where gaming is a major part of daily life.

Homeworkers

Great for video meetings, cloud applications and transferring large files.

Smart homes

Great for homes packed with connected devices, from smart speakers to security cameras.

But remember...

If you're frustrated by blank spots or patchy coverage rather than speed itself, TalkTalk U has the answers. Because sometimes it’s not about how fast… it’s about how far. Great Wi-Fi shouldn’t just enter your home; it needs to reach you. TalkTalk U is the game-changing plan built to do all this and then some.
