The best Samsung Galaxy S8 deals in January 2018

Our comparison chart below lists all the current cheapest prices of Samsung's brilliant 2017 flagship phone.

Here you can find, filter and compare all of the best Samsung Galaxy S8 deals currently available in the UK.

You have to be pretty savvy if you want to grab the very cheapest S8 prices.

Samsung Galaxy S8 | £175 upfront (with 10OFF code) | 4GB data | Unlimited minutes and texts | £23pm
Despite its rather disappointing £50 price increase, this Vodafone deal on the Galaxy S8 probably remains our fave for the moment. £23 is as low as you'll pay for your monthly bills on this handset, and the overall two year cost is one of the cheapest out there. It's great value for a fantastic phone less than one year old from a phone manufacturer at the top of its game. Total cost over 24 months is £727

Samsung Galaxy S8 | £100 upfront (with 10OFF code) | 3GB data | Unlimited minutes and texts | £27pm
Around Black Friday O2 was the go-to network for the Samsung Galaxy S8. But since it pulled its killer 12GB tariffs, it just doesn't compete any longer with the competition. This 3GB deal is as cheap as it comes: £27 per month is attractive, but paying £100 upfront isn't - still at least Mobiles.co.uk just knocked £25 off the price. Total cost over 24 months is £748

Samsung Galaxy S8 | £92 upfront | 5GB data | Unlimited minutes and texts | £27.99pm
We saw some remarkable prices around Black Friday on the Galaxy S8 and the handset sold like the proverbial. This tariff came along a couple of weeks ago and the free upfront cost bettered them! But Mobile Phones Direct has unfortunately now seen sense and increased it back up again. Still excellent value, though. Total cost over 24 months is £763.76

Samsung Galaxy S8 | FREE upfront | 30GB data | Unlimited minutes and texts | £34pm
Big data deals haven't been immune to the general fall in price of the Galaxy S8 and this is a seriously good Galaxy S8 deal on Three if you use your phone a lot away from Wi-Fi. What's more, Mobile Phones Direct has just removed the upfront cost entirely - no other network comes close to Three for big data at the moment. Total cost over 24 months is £816

Samsung Galaxy S8: consider going SIM only

If you’re determined to get yourself a Samsung Galaxy S8, the most economical way of doing it is to buy the phone outright and pair it with a SIM only deal. The £689 RRP is certainly high, but it can still work out a little cheaper on average over the two years - especially now that some retailers are selling it for £100 less than that. Check out our page dedicated to the best unlocked SIM free Galaxy S8 prices.

Samsung Galaxy S8 review

The Galaxy S8 is a brilliant phone - another success for Samsung

Screen size: 5.8-inches | Resolution: 1440 x 2560 | Rear camera: 12MP | Weight: 155g | OS: Android 7 | RAM: 4GB | Storage: 64GB | External storage: microSD up to 256GB | Battery: 3600mAh

Amazing, large display
Huge power
Great camera
Irritating biometric unlocking

With the Galaxy S8, Samsung is getting nearer and nearer to smartphone perfection. The bezel-less design is something a little bit special in an area of tech that can sometimes feel like it's standing still. There are advancements with the splendid screen and fantastic 12MP camera, too.

Samsung Galaxy S8 deals by network

Whatever your favoured network, however much data, calls and texts allowance you need, we've trawled the market to pick out our favourite Galaxy S8 deals below.

Samsung Galaxy S8 | £165 upfront (with 10OFF code) | 2GB data | Unlimited minutes and texts | £22.99pm
If you like the idea of getting your bill for the next 24 months and seeing a ridiculously low amount, then this is the tariff for you. It used to be among the best ever S8 deals, but has just gone up £50 at the outset. That makes it much less appealing,l but...well, did we mention those bills? Total cost over 24 months is £716.76

Samsung Galaxy S8 | FREE upfront | 15GB data | Unlimited mins and texts | £37.99pm
This 15GB price from the UK's fastest 4G network is very attractive, especially thanks to the free handset. You also get unlimited calls and texts, £119 cashback, as well as EE's usual perks - 6 months of Apple Music, 3 months of the BT Sport app and the fastest 4G speeds in the UK. Tempted? You should be! Total cost over 24 months is £911.76

Samsung Galaxy S8 | £83.99 upfront | 10GB data | Unlimited minutes and texts | £35pm
Pah! This tariff just got much worse...again. For around the same price, you used to get double the data. For a wee while in November, O2 was flexing its muscles on bigger data deals and showing Three who was boss. But things are back to normal now...unfortunately. Total cost over 24 months is £923.99

The best Samsung Galaxy S8 deals on Vodafone

Samsung Galaxy S8 | £175 upfront (with 10OFF code) | 4GB data | Unlimited minutes and texts | £23pm
Despite its rather disappointing £50 price increase, this Vodafone deal on the Galaxy S8 probably remains our fave for the moment. £23 is as low as you'll pay for your monthly bills on this handset, and the overall two year cost is one of the cheapest out there. It's great value for a fantastic phone less than one year old from a phone manufacturer at the top of its game. Total cost over 24 months is £727

Samsung Galaxy S8 | £174.99 upfront | 16GB data | Unlimited minutes and texts | £36pm
16GB is a stack of data to stream, surf and play with. But this isn't a very good tariff. We're simply listing it here to demonstrate what a massive leap in price it is on Vodafone if you want anything more than 4GB of data on the S8. Total cost over 24 months is £1038.99
