Apple's flagship smartphone, the iPhone 5s, is available on contract or SIM-Free from lots of UK carriers and phone stores. That's why it can be difficult to figure out what the best iPhone 5S deal is. Here, we round up iPhone 5S tariffs, contracts and pricing in the UK to help you find the best iPhone 5S deal for you. 

Best iPhone 5S deals: SIM-Free iPhone 5S prices

If you have the cash, you can grab yourself and iPhone 5S without a contract (a.k.a unlocked or SIM-Free) from Apple’s online store, from its physical stores and from third-party resellers.

The iPhone 5s comes in three different colours - gold, silver and space grey - and offers a choice of 16GB, 32GB or 64GB storage capacities.

From Apple, it'll cost you £549 for a 16GB iPhone 5S, £629 for a 32GB iPhone 5S or £709 for a 64GB iPhone 5S.

Obviously you also will need to factor in the monthly outlay of whatever contract or pay-as-you-go deal you opt for to get your minutes, texts and data.

The price of the iPhone 5S will be the same or very similar from most resellers, but if we spot an exceptional deal we'll let you know here.

Best iPhone 5S deals: iPhone 5S contracts

Buying an iPhone 5S on a contract is a more complicated business thanks to the huge variation of tariffs and networks on offer. We've investigated all of the biggest carriers to discover the best iPhone 5S deals for you. We've highlighted our pick of the best deals for various different needs here, and you can scroll down to find a breakdown of some of the best all-round deals from EE, O2, Virgin Mobile, Three, Vodafone, Tesco Mobile, Carphone Warehouse and Phones 4U.

Note: Contract prices and tariffs are ever changing, but these deals are correct at time of writing. We'll be checking back and updating this article regularly.

Which iPhone 5S contract is best for data

If you want unlimited data, we'd recommend checking out Three's iPhone 5S contracts. You can get yourself a 32GB or 64GB iPhone 5S for £29.99 upfront and either £43 or £48 per month, with 600 minutes and unlimited data allowance. See below for more details.

Which iPhone 5S contract gives a free handset 

For a free iPhone 5S, you'll want to go to either O2 or Tesco Mobile. Take a look below for more details about iPhone 5S contracts with those carriers.

Which iPhone 5S contract has the lowest monthly cost 

You can get the monthly cost of the iPhone 5S really low, but it'll probably mean you'll hardly get any minutes, texts or data. The lowest monthly cost we've found with allowances that'll actually be worthwhile is from Carphone Warehouse, details of which you can find below.

Which iPhone 5S contract is cheapest over two years 

All of the contracts we've listed here span 24 months (two years). There are 12 months and 18 months contracts available but that'll push the monthly and upfront prices up. The cheapest overall contract we found (ie. the contract that'll cost you the least in total over the two years you've signed up for) is from Carphone Warehouse, at just under £900. There will be cheaper deals out there, but they'll only give you a tiny allowance, so we think you'll be better off opting for one of the deals we've picked out here.

Best iPhone 5S deals: Virgin Mobile

If you already have Virgin Broadband, TV or home phone, you can get reasonable deals from Virgin Mobile. Here, we've listed some of those deals. We wouldn't recommend opting for Virgin Mobile if you're not already a Virgin customer, as it'll probably be more expensive than other carrier options.
