BT Infinity: Superfast, superior value?

BT Infinity fibre optic broadband is faster and more reliable than regular broadband, and cheaper than you might think. It's now available to over three-quarters of homes in the UK, but is it the right choice for you? Find out what the pros and cons are right here...

There's never been a better time to get superfast broadband. Almost every major broadband provider in the UK now offers a fibre package, and this fierce competition has made prices collapse like a house made of tissues.

That's as true for BT Infinity as it is for the other fibre services - it's unlikely to cost considerably more than what many of you are already paying. In fact, in some cases, it'll cost less.

But before we get into that, let's look at what BT Infinity is, and what's good and bad about it.

What is BT Infinity?

BT Infinity is BT ( fibre optic broadband. Fibre optic broadband is a big step forward from 'standard' broadband, offering much, much faster speeds. Comparing the two is like comparing a mid-range Ford Focus to a top-end Ferrari - both get you where you want to go, but you'll get there faster and in more style with the latter.

In addition - and, admittedly, less like a Ferrari - fibre optic broadband is much more reliable, capable of supporting more users at the same time, and less susceptible to dropped connections than regular broadband.

What speeds can you get with BT Infinity?

BT is not the fastest fibre optic broadbandavailable. Virgin Media offers download speeds of up to 152Mb, and is generally recognised as the fastest national broadband provider in the UK. BT Infinity is no slouch though, but if pure speed is what you want, you may want to consider Virgin Media or, if it offers broadband where you live, Hyperoptic.

There are three BT Infinity packages available:

BT Infinity 1: Up to 38Mb download speed, 20GB monthly usage

Unlimited BT Infinity 1: Up to 38Mb download speed, totally unlimited usage

Unimited BT Infinity 2: Up to 76Mb download speed, totally unlimited usage

BT Infinity 1 offers download speeds that are up to more than double the national average for home broadband, while BT Infinity 2 offers speed that are up to more than four times that.

Is BT Infinity any good?

Well, it has a cool-sounding name, for one thing. Of course, there are a lot of sensible reasons to get it too, like these...

It's affordable

BT Infinity may not be as expensive as you think - that's actually one way it's not like a Ferrari. The cost of fibre is getting less and less, as providers fight to make their service stand out, so it's possible to get BT Infinity for not much more than you'd pay for a standard broadband package. If you find the right special offer, it can be even less, so make sure you use our postcode checker to compare all the options and find the best deal available. 

It's great for movies and TV

If you like to watch TV and movies online via streaming services like BBC iPlayer and Netflix you'll find fibre lets you watch things smoothly, in high-definition (HD), with minimal loading time. If you prefer to download your entertainment, you'll find the fastest fibre packages you can download a DVD-quality movie in as little as two or three minutes.

It's also great for BT TV, which uses your internet connection to deliver catch-up TV and BT Vision on-demand programmes and films. Plus, if you have a BT Infinity package and BT TV you get BT Sport on your TV for free.

If you're an exisiting BT customer, but one of the BT Infinity + BT TV deals above has tickled your fancy, phone BT on 0800 434 6052 to see if you can get in on the action.

It's great for families and shared houses

When lots of people use an internet connection at the same time, it slows down. It's a common problem for families where everyone's constantly using web-connected phones, tablets and laptops. Fibre alleviates the problem - it'll still slow down, but because it's so much faster to start with, it's unlikely it will ever become unusable. That means fewer limits on what you can do with the internet, and hopefully, fewer arguments.

It's reliable

Fibre optic broadband offers a more stable connection than standard broadband - it is less prone to slowing down or dropping out.

It comes with the BT Home Hub 5

BT's router is one of the best available from any provider, offering good range and the ability to automatically compensate for interference. It's quite the looker too.

Is BT Infinity expensive?

While BT Infinity is cheaper than it used to be, you may find other fibre options are even more affordable. Make sure you compare all providers' fibre options before making a decision.

It's also not necessarily the fastest fibre service on the market. Virgin Media offers speeds of up to 100Mb, and is recognised by telecoms regulator Ofcom as the fastest broadband provider in the UK. BT Infinity's no slouch, but if pure speed is what you want, you may want to look there first.

A potentially more serious problem is that you might not be able to get it at all. Fibre is not available everywhere in the UK - particularly in rural areas.

Is BT Infinity available in my area?

Good question. Where do you live?

There's actually a good chance it might already be there. While fibre optic broadband isn't available everywhere, over three-quarters of homes and businesses in the UK now have access to it. To see if BT Infinity is available in your area, use our postcode checker or the availability checker on BT's website.

Unfortunately, if you live in the countryside, you may not have access to fibre yet. BT ( is in the process of rolling out fibre across the UK, and the government has stumped up a big chunk of cash to make this happen, with the goal of delivering access to fibre to 95% of the population by 2017.

Whether this will happen by then is unclear - the government's already pushed back its broadband roll-out targets once already, but it's progressing at least.
