BT Broadband features and review

The big daddy of UK broadband, BT owns the infrastructure that most fixed line providers (except Virgin Media) use to put ADSL, ADSL2+ and now fibre optic internet into your home.

It's the biggest fixed line broadband provider by user numbers, its 'Home Hub' wireless router is well regarded, and it offers a good variety of products - everything from a straight broadband deal to offers including mobile phones and television services. And with the introduction of BT Sport in 2013 the firm is now competing directly with premium TV providers.

BT claims to be the world's oldest communications company, dating back to the Electric Telegraph Company of 1846. British Telecom (as it was known) was formerly part of the Post Office - then a government department - but became a plc in 1984. It now has more than 7 million subscribers (including Plusnet, which it owns) to its BT Broadband products.

BT launched its first consumer broadband services in 2000, with blazing fast (for the time) speeds of 250Kb - 2Mb. That same year it began offering local loop unbundling, allowing other providers to install equipment in BT exchanges - this led to the growth of popular ISPs such as Easynet (later purchased by Sky) and BE Broadband.

If you’re considering BT Broadband deals for your next broadband service you might find the choice confusing, but Broadband Genie is here to guide you through the broadband maze and find the perfect package.

What does BT Broadband offer?

Broadband

BT provides both ADSL and fibre optic broadband over a fixed line connection to most homes and businesses across the country. This is the same selection of services as offered by most other fixed line ISPs, which are reselling access to the BT Openreach network.

At present the vast majority of BT Broadband fibre connections use a technology known as ‘Fibre To The Cabinet’ (FTTC) which means the fibre line runs to the street cabinets and the regular telephone cable carries it into your premises. But BT is gradually deploying the far superior Fibre To The Premises (FTTP, or FTTH - To The Home) which means the fibre line runs all the way into a property and can deliver much greater speeds. Sadly availability is limited at present (unless you’re willing to pay a hefty installation charge) but should be expanded in the not-too-distant future.

Phone

A phone line is required for all BT Broadband packages - the price displayed on our comparison tables is the monthly cost of both the broadband and line rental.

Most BT packages offer some inclusive calling too, but if you wish to add anytime calls or international calls you can do so during the sign-up process.

TV

In addition to broadband, BT also operates its own TV service. Available as a bundle with broadband and phone, BT TV includes a YouView box which provides access to catch-up and on-demand content, with recording features on some models. Optional premium channels are available to go alongside the Freeview broadcasts. To find out more read a full guide on our BT TV page.

BT Broadband coverage and speed

BT Broadband availability

Just about everyone in the country will be able to get some kind of BT Broadband service. BT's ADSL footprint covers the vast majority of UK homes and businesses, and fibre broadband is now available to more than 80% of premises.

All you need is to have, or be able to install, a BT landline and to be within range of a BT telephone exchange.

You can quickly see what's available in your area by entering a postcode into the postcode search on our comparison tables to filter results by location.

BT Broadband speed

BT broadband currently offers two different types of home broadband services, with a variety of speeds on offer depending on what’s available in your location.

The type of broadband and speed you can get will depend on the services offered at the exchange, the condition of your line and distance from the exchange.

ADSL broadband

BT ADSL broadband uses the telephone line to deliver download speeds up to 17Mb and upload rates up to 1Mb. ADSL is usually the cheapest way to get broadband and it is available to the vast majority of homes.

However, keep in mind that while advertised as "up to" 17Mb the actual performance may be far slower, depending on the condition of the lines and distance from the exchange. In many cases ADSL users will still be able to enjoy everything the internet has to offer, but large file transfers and other demanding tasks could take a long time. This is a limitation of the technology and is the same for all ADSL broadband providers. If you require faster speeds, look to fibre broadband.

Fibre broadband

BT Infinity packages are BT Broadband deals offering fast fibre optic connectivity. Fibre broadband is significantly quicker than ADSL, with a maximum download speed of either 52Mb or 76Mb and upload speed up to 20Mb. This makes it ideal for large downloads, streaming HD video, uploading files to cloud storage and handling the demands of a family or shared household where many people may use the connection at once. It is a little more expensive than ADSL but still very affordable.

BT Broadband usage limits and traffic management

Some of the cheapest BT Broadband deals will come with a monthly data cap, which can be acceptable for very light users. But the majority of BT deals include unlimited usage, and these are usually the best option for most people.

BT does not implement traffic management on any of its services so your speed will not be restricted, no matter the time of day or how much you upload or download.

BT Broadband review - the Broadband Genie verdict

We like...

  • Truly unlimited
  • Great value TV bundles
  • Cheapest fibre package is fast

We don’t like...

  • Expensive after the first year
  • Customer service needs improvement

BT can offer a good value broadband deal with excellent speeds and generally reliable service. Its TV service is very affordable with lots of extra features, so it’s a great option for a cheap broadband and TV bundle. We especially like that the minimum fibre speed is up to 52Mb - a significant upgrade over the 38Mb offered by other ISPs. And all the unlimited packages are truly unlimited.

But you do need to be aware of the full costs after the first year. While it has some very competitive introductory deals (and frequent special offers such as shopping vouchers) the price can increase sharply after 12 months. This shouldn’t put you off, but it will be worth making a note of the contract end date so you can contact BT to see what else it can offer once that cheap initial term has ended. It also has to be said that BT’s performance on customer and tech support in our annual home broadband survey is less than stellar, though this is likely due in part to the sheer number of subscribers it has (and the majority of them seem perfectly happy with the service).

Broadband Genie Home Broadband Awards

Broadband Genie Survey Winner

Some mixed results for BT in the 2016 Home Broadband Survey.

Once again the provider came second for speed with an average 21.99Mb download. It was also the winner of the Best Router award, with BT customers being the most chuffed with their Home Hub.

However BT was lagging behind in other areas, particularly customer care and value.
