However, BT offers have the edge - not only can you regularly get money off or get it for free for the first months of your contract, you're also likely to land yourself a Sainsbury's gift card worth a tidy little sum.

Winner

BT Infinity

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 50% and 60% of homes in the UK, BT fibre optic broadband is available to over 80% of homes and businesses.

Winner

BT Infinity

Bundling

When it comes to home phone, BT Infinity 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 Infinity 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 Infinity 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, theres's the option of adding the amazing Sky Q for the ultimate TV experience.

Winner

Sky Fibre 

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

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 for 2015 of 80% - well above average - and BT got 60% - 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…

Winner

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 Infinity 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 Infinity 1 or 2, does.

All BT Infinity 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 at no extra cost with all BT Infinity packages.

BT Infinity

Packages

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

Package Download speed  Monthly usage 
Sky Fibre Up to 38Mb 25GB 
Sky Fibre Unlimited Up to 38Mb  Unlimited
Sky Fibre Unlimited Pro Up to 76M  Unlimited

BT Infinity keeps it just as simple:

Package Download speed  Monthly usage 
BT Infinity 1 Up to 52Mb  25GB 
Unlimited BT Infinity 1 Up to 52Mb  Unlimited 
Unlimited BT Infinity 2 Up to 76Mb  Unlimited 

It's close - the only difference, in fact, is the speed of each provider's basic fibre package. That's a clear winner then, we suppose.

Winner

BT Infinity

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. 

At the time of writing, BT Infinity packages cost from £28.99 to £42.50 per month including line rental. Sky Fibre costs from £27.40 to £47.40, again per month including line rental.

So Sky's cheapest package is cheaper than BT, but its most expensive package is more expensive than BT. Really, there's not a whole lot of difference - we recommend using our comparison tool to see what deals are on at the time you're ordering your broadband.

Winner

It's a tie

Router

All BT Infinity 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.

Winner

BT Infinity... just

Speed

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

The only difference is in the basic fibre package. Sky offers download speeds up to 38Mb, while BT offers up to 52Mb. That equals a clear winner to us.

Winner

BT Infinity

Usage

You can get BT Infinity and Sky Fibre with either a monthly 25GB usage allowance, or 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 Infinity 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 could not be separated on their advertised 'up to' speeds, the speeds 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.

Overall winner

BT Infinity!
