If your current broadband service just isn’t doing the job it may be time to think about an upgrade to superfast fibre broadband.

But what is superfast, and do you need it? This guide will tell you everything you need to know.

What is superfast broadband and how does it work?

Superfast broadband is a high speed internet connection which provides much quicker internet speeds than standard ADSL broadband.

It is a general term referring to the speed, not a specific type of broadband. 

Many homes and businesses now have the option of getting a superfast broadband deal to significantly improve broadband speeds.

How fast is superfast broadband?

At Broadband Genie we use the Ofcom definition of superfast broadband to mean a connection with a download speed of 30Mb+ (upload speed is not defined, but you can expect this to be reasonably fast too). Like ultrafast, "superfast" is a simplified label for broadly categorising internet speeds and not an official technical term with any universally recognised definition.

The Ofcom definition means the standard ADSL broadband available to most homes and businesses is not what we would consider superfast. But superfast is widely available using other broadband technologies. You can get superfast broadband right now with 4G mobile internet, satellite broadband, Openreach (BT line) fibre optic and Virgin Media fibre.

Here are the average or up to speeds you can expect to get with different types of superfast broadband:

  • Openreach (BT line) fibre optic: 35-38Mb / 50Mb (BT Infinity only) / 63-68Mb
  • Virgin Media: 54Mb / 108Mb / 213Mb / 362Mb
  • 4G mobile broadband: up to 21Mb / up to 40Mb / up to 60Mb / up to 100Mb
  • Satellite broadband: up to 30Mb

Average speeds are based on 50% of the provider’s customers so provide a fairly accurate portrayal of the actual performance, though you should always be given a personalised speed estimate when joining a provider.

An “up to” speed is the maximum possible speed, but in practice the performance could be much lower.

For mobile broadband - unlike fixed line home broadband - you will not receive an estimate of speed from a mobile network as performance is highly variable depending on numerous factors.

For more help with this topic our guide to broadband speeds goes into a lot more detail.


Superfast broadband is a broad term and not a specific type of connection, but most of the superfast home broadband services in the UK use one of two broadband technologies: FTTC or HFC. You may also hear about FTTH or FTTP, which offer even greater speeds.

Fibre to the Cabinet (FTTC)
This is the broadband service offered by most ISPs, using the Openreach (BT) telephone network. An FTTC connection uses fibre optic lines up to street cabinets then it’s carried into our homes with the old copper telephone line.

Hybrid Fibre Coaxial (HFC)
HFC is the technology used by Virgin Media. Like FTTC it uses fibre optic cables to street cabinets, but then relies on coaxial cable to reach into homes. This allows Virgin Media to offer faster broadband speeds, as well as telephone and TV services. 

Fibre To The Home/Premises (FTTH or FTTP)
Another type of broadband technology that’s less common but will (hopefully!) dominate in the future is Fibre To The Home/Premises (FTTH or FTTP). This is a “full fibre” connection which eliminates the old copper telephone wires and can provide very speedy “ultrafast” broadband.

Can I get superfast broadband?

You probably can get superfast broadband right now. More than 94% of premises now have access to fixed line superfast connectivity, many places have 4G network signal, and for everyone else there is always satellite broadband. 

The rollout of superfast broadband has been going on for several years, and aims to provide superfast connectivity to the vast majority of premises by 2020. In most cases superfast will be delivered over an Openreach or Virgin Media line. The Openreach site has a map showing superfast coverage and future deployments.

You can find out if superfast is available in your home right here on Broadband Genie - enter your postcode into our broadband comparison tables to filter the results by location. This will quickly show you what superfast services are available in your area.

Alternatives to fixed line superfast broadband

For most of us a fixed line broadband connection using the Openreach or Virgin Media network is the best way to get superfast, but not everyone will have this option. If you’re in this situation there are alternatives: 

Satellite broadband
Satellite internet works anywhere and is useful if you live in a very remote area; the only requirement is that you must be able to mount a dish with a clear view of the sky. It’s reasonably quick too - most satellite ISPs can offer download speeds up to 30Mb and upload speeds up to 6Mb. 

Satellite is a little more expensive though. Setup can be several hundred pounds, and the running costs are a little higher than other types of broadband. Unlimited satellite broadband is especially pricey, but most satellite ISPs offer cheaper packages with unlimited usage in off-peak hours.

The biggest downside is that satellite has a very high latency, making it unsuitable for things like online gaming and remote desktop access.

4G mobile broadband
4G mobile networks can provide a fairly reliable superfast connection so long as you can get a strong signal. Some networks - notably EE and Three - are catering to home users with packages that include 4G routers and a larger data usage caps. 

But of course you need to be able to get a signal, and if you don’t have good fixed line connectivity it’s possible that there isn’t much in the way of a mobile network in your area either. If there’s a weak signal it is possible to get much faster mobile broadband by using an external antenna to boost the signal.

Do I need superfast?

Superfast broadband is great for anyone who regularly uses their internet for demanding data-heavy activities such as HD video streaming (Netflix, iPlayer, etc), downloading large files and gaming. It’s also recommended if the connection is shared with other people. 

However, if the broadband is mostly for light usage such as web browsing, social media and email then you’re not really going to see much benefit from the faster connection and could save money with a cheaper ADSL service.

Superfast broadband advantages

  • Fast! Superfast broadband is significantly quicker than ADSL.
  • Better upload speeds. In addition to fast download rates you can also expect a much quicker upload speed, which is useful if you frequently transfer large files.
  • Affordable. Superfast broadband is not expensive and there are always lots of great value special offers.

Superfast broadband disadvantages

  • Not available everywhere. While superfast broadband over a fixed line does have 94%+ coverage there are still many homes which cannot get it. Alternatives are available (see above) but may not be suitable for everyone.
  • ADSL is cheaper. While superfast isn’t expensive, it does still cost a little more than 17Mb ADSL2+. If you don’t need the extra speed you can save money with a cheap broadband deal.
