Deals

Sky Fibre ain't backwards in coming forwards when it comes to deals - you can regularly get it for a cut price, or with some kind of prepaid card or reward voucher included.

However, BT offers are similarly good - not only can you regularly get money off or get it for free for the first months of your contract, it's also land yourself a prepaid card or voucher.

*Average speeds are based on the download speeds of at least 50% of customers at peak time (8pm to 10pm). Speed can be affected by a range of technical and environmental factors. The speed you receive where you live may be lower than that listed above. You can check the estimated speed to your property prior to purchasing.

This is a very difficult category to judge - some weeks BT is better, some weeks Sky will have the edge - so make sure you compare broadband before making any decisions. If pushed though, we'd say BT's deals are ever so slightly better overall.

Availability

When it comes to whether you can actually get it, BT (www.bt.com) has Sky (www.sky.com) licked before the latter has finished lacing up its gloves. While Sky Fibre is available to between 60% and 70% of homes in the UK, BT fibre optic broadband is available to over 80% of homes and businesses.

Bundling

When it comes to home phone, BT fibre can be bundled with inclusive weekend, evening and weekend, and anytime calls. Sky Fibre can bundled with weekend, anytime UK and anytime international calls. You can add inclusive and discounted international calls to BT fibre too though, so let's call that a no score draw.

When it comes to TV, there can only be one winner. While bundling BT TV with BT fibre costs less than half what it costs to bundle Sky TV with Sky Fibre, Sky TV offers just about every channel it's possible to get in the UK, offers every Sky Sports channel, has more HD channels, and has just about every feature you can think of. Plus you get Sky Q - a far better set top box than BT YouView.

Complaints

According to the last report UK communications regulator Ofcom published about complaints made to providers, BT received more complaints about its broadband than average, while Sky received fewer than average. In fact, Sky has received fewer complaints about its broadband than BT has since at least 2012, so there's only one way this is going…

Winner

Winner

Sky Fibre

Customer service

Again we look to Ofcom to referee this round. In its latest report on satisfaction with the customer service of providers, Sky got overall satisfaction score well above average; and BT got a little below average. In fact, Ofcom research has found Sky's customer service to be better than BT's in three out of the last four years. Again, there's no contest…

Sky Fibre

Extras

You get Sky Broadband Shield, an online tool that prevents access to malware-infected and phishing sites and allows you to control what kind of content can be accessed at different times of day, and a free trial of McAfee Security Centre with all Sky Fibre packages. You also get unlimited use of Sky WiFi, which is available in over 20,000 locations across the country, at no extra cost.

BT fibre matches it blow for blow though. All packages comes with BT Parental Controls. Although these don't stop anyone from going onto malware-infected and phishing sites like Sky Broadband Shield, BT NetProtect Plus, which is included with Unlimited BT fibre 1 or 2, does.

All BT fibre packages also include unlimited use of BT Wi-fi, which outstrips Sky WiFi somewhat when it comes to availability with more than five million hotspots in the UK and seven million abroad.

However, it's BT Sport which sees BT take this round - you get all three channels online and on your phone incredibly cheaply with all BT fibre packages.

Packages

Sky Fibre keeps it simple - it comes in three flavours.

Package Download speed Monthly usage
Sky Fibre Average 36Mb 25GB
Sky Fibre Unlimited Average 36Mb Unlimited
Sky Fibre Max Average 63Mb Unlimited

BT has a slightly expanded menu, though most people will only be able to get the first three:

Package Download speed Monthly usage
BT Superfast Fibre Essential Average 36Mb Unlimited
BT Superfast Fibre Average 50Mb Unlimited
BT Superfast Fibre 2 Average 67Mb Unlimited
BT Ultrafast 1 Average 145Mb Unlimited
BT Ultrafast 2 Average 300Mb Unlimited

BT's base fibre package is faster than Sky's. It also sells ultrafast packages, though they're not yet widely available (we expect this to change in the coming years).

Price

Price is difficult to judge - both providers have similarly priced packages, and both also regularly have offers and deals going on that can push one of them cheaper than the other.

In our experience, Sky generally works out slightly cheaper than BT, for broadband at least. We do recommend checking deals to see if that is currently the case, however.

Really though, there's not a whole lot of difference - we recommend using our comparison tool above to see what deals are on at the time you're ordering your broadband.

Sky Fibre - but this could change depending what deals are currently available

Router

All BT fibre packages come with the BT Smart Hub, which has some of the best router tech you can get from a provider. It's got dual-band Wi-Fi with the latest 'wireless ac' standards, some top security, and advanced interference filters to give you a better and clearer Wi-Fi connection. It's pretty darn good.

With Sky Fibre, however, you'll get a Sky Hub - which isn't quite as good, with the last generation of Wi-Fi (n) and slower USB ports, but it'll still do the job just fine. You've also got the option to upgrade to the Sky Q Hub, a far better router with all the latest tech.

But it still doesn't quite rival the BT Smart Hub - there's no interference filter or smart scanner here.

BT fibre optic broadband... just

Speed

Tricky round to call this, as Sky uses BT's network to deliver its broadband, which means the advertised download and upload speeds for BT and Sky Fibre are more or less exactly the same.

But while Sky only offers average download speeds of 36Mb and 63Mb, BT also has a middle-tier package with average speeds of 50Mb. That equals a clear winner to us.

Winner

Usage

You can get both BT and Sky Fibre with totally unlimited usage. And you'll never be artificially slowed down, no matter what you're doing, as traffic management doesn't apply to these packages.

So... there's no difference whatsoever, really.

Winner

It's a tie

Verdict

Despite a late resurgence from Sky Fibre, we're awarding BT the victory on points, thanks to its performance in the availability, extras and price rounds. It was a closely-fought encounter, with Sky Fibre more than holding its own, dominating the complaints and customer service rounds - something to bear in mind when choosing between the two combatants.

You should also consider that, while the two offer similar speeds, what you'll actually get will depend on where you live. You can get an estimate of the speeds you'll get at your address by going to www.bt.com and www.sky.com, clicking on the package you're interested and entering your postcode and telephone number.
