BT and Sky are two of the biggest high-speed broadband providers in the UK, with millions of customers between them.

We’ve compared the two providers based on what they offer, costs and customer service. But it is worth remembering that if you are looking for the best broadband deal, especially as prices go up, then there is a wide range of different broadband providers to choose from. While BT and Sky may be two of the largest providers in the country, it is still possible to find a cheaper deal elsewhere.

It is good practice to compare as many broadband providers as possible before signing up for a deal. Make sure you select a plan that gives you the speeds and data allowance you need, at a price that’s right for you.

But if you are looking to switch to either Sky or BT, then this is what they provide.


 What type of packages does BT offer? 

There are two main options to choose from: a broadband deal, or a bundled broadband and TV deal. If you don’t use a landline phone, BT offers broadband-only deals, but it is worth remembering that you’ll have to rely on your mobile to make or receive any calls. 

 What is BT’s availability like? 

According to BT its broadband packages are available to more households than any other provider in the country. Its Fibre packages are accessible to 91% of the UK. BT Full Fibre broadband, where rather than the signal coming from a copper cable, the fibre cable connects straight to your home, is currently only accessible to 8% of the UK. But the technology and broadband packages are becoming increasingly available across the country.  

 How much does BT broadband cost? 

How much you pay for your broadband is dependent on which broadband package you decide is best for you. BT’s Fibre Essential deal, which allows you to browse the internet and stream content on one or two devices at once, costs £28.99 a month for 12 months, with an additional £29.99 upfront ‘activation fee’. 

Another option is BT's Fibre 1 deal, which allows you to browse, stream and download on a few devices at once. It is available for £29.99 a month with an upfront fee of £29.99. Other packages that boast faster speeds are available, including the Fibre 100 and Fibre 250 deals at £39.99 an £49.99 a month for 24 months respectively.
