BT broadband vs Sky broadband

Wednesday, November 8th 2017

Trying to choose between Sky and BT? These two major heavyweights compete fiercely in the UK broadband market, and, unless you are also after a TV package, there is little to choose between them.

Which of the two providers you go for will depend on what you want out of your broadband service. Whether you want a straighforward standard broadband package, or a fibre package with all the extras, Sky or BT should fit the bill.

At a glance

BT and Sky offer both standard broadband and fibre packages with a range of speeds on offer. Sky can have the edge over BT when it comes to price and contract length, and also offers a superior TV service, but BT offers some nice extras such as BT Sport (if you also take BT TV) and wi-fi. Both providers regularly offer tempting vouchers or discounts.

Package comparison


BT's standard broadband service is widely available across the UK. To take any broadband service with BT you have to also have a BT phone line. Line rental is now included in the advertised price. Various phone packages are available depending on how much you use your phone – everything from weekends only to anytime and international.

BT Infinity comes with the new BT Smart Hub router and provides maximum fibre optic speeds of 76Mbps to the majority of its fibre network. That’s enough to download an HD movie in ten minutes and a music album in four seconds.

Get BT Broadband


Sky offers two ADSL broadband and three fibre broadband products. As with BT, you must have a live landline to be able to receive Sky's broadband services. Sky now includes its line rental charge in its prices.

Sky's broadband packages come with a number of features including a Sky Hub wireless router and a Pay-as-You-Talk option for calls – other, inclusive calls packages are available to bolt on if you wish. As with BT, Sky's top fibre package, Sky Fibre Max, offers up to 76Mbps download speeds.

Customer service


BT has a mixed reputation for customer service, but in most formal polls it comes out as middling. It's not the best, but its not the worst either.


In comparison, Sky invariably rates very well for customer satisfaction, with a higher rate of satisfied customers than BT.

Technology and equipment


The BT Smart Hub has power-saving features, switching the devices to low energy consumption mode when not in use. You can simultaneously connect a large number of devices to the hubs, sharing your connection via four Ethernet ports on the back of each device or through wi-fi.


The Sky broadband package comes with a Sky Hub. However it only comes with single band technology rather than dual band - so your wi-fi signal won't be as strong as the BT Smart Hub. It also allows you to connect several devices to the home network.

Extra features


In addition to broadband, BT customers also get a range of extras. BT Sport is currently free for three months with BT broadband, and costing just £7 thereafter. Alternatively, new customers can sign up to BT TV as well for an extra fiver a month and get BT Sport included free for the full 18-month contract.

You’ll also get access to around five million wi-fi hotspots around the UK, and online storage via the BT Cloud. You can also add a BT Mobile SIM at a discounted price. Plans start from £5 per month for BT broadband customers.


Sky customers also get wi-fi hotspot access, but not as many as BT users do – Sky only has around 20,000 locations. You get the Sky Hub router to enable you to wirelessly connect a number of devices to the internet. You’ll also get access to Sky’s online on-demand service Sky Go if you plump for a broadband package with Sky TV.


Whether you opt for Sky or BT you’ll be getting a good service with improving levels of customer service and impressive equipment. If you are looking for a straightforward standard broadband package we advise you choose the cheapest option. If you like the idea of free wi-fi, go for BT as it offers the biggest network, whereas if you are looking for broadband and TV, Sky is the way to go as it offers the superior TV service.
