Stop the presses! Samsung Galaxy S8 deals just went berserk. Carpone Warehouse-owned retailer Mobiles.co.uk has released some new tariffs that bring S8 prices down to a new low. We can't remember a time when Galaxy S8 deals have been cheaper.

That means you can now get it for less than £20 per month without paying silly money upfront. And before you get your calculators out, yes that does mean less than £600 over the course of the two year term.

Unsurprisingly since the Samsung Galaxy S9 emerged, the landscape for Galaxy S8 deals has become even prettier. Even though the successor isn't that much of an improvement on the S8, contract prices on the older phone have gone down saving you a packet over the S9.

Our comparison chart below lists all the current cheapest prices of Samsung's brilliant 2017 flagship phone. Notwithstanding the release of the S9, Galaxy Note 8 and iPhone X, the Samsung Galaxy S8 remains one of the most impressive phones ever released. Here you can find, filter and compare all of the best Samsung Galaxy S8 deals currently available in the UK.

Underneath the comparison tool, you'll find our editors' selections for all of the best value S8 deals currently available from the major networks, EE, O2, Vodafone and Three.

Samsung Galaxy S8 | £65 upfront | 1GB data | Unlimited minutes and texts | £18pm

Samsung Galaxy S8 | £45 upfront (with 10OFF code) | 4GB data | Unlimited minutes and texts | £23pm
Despite the sheer affordability of the above deal, we think we actually prefer this Samsung S8 deal on Vodafone. That's because you don't have to cope with meagre data as 4GB a month is relatively good. It's a new lower price from the retailer and it's an easy choice for our current Editor's Pick slot. Total cost over 24 months is £597

Samsung Galaxy S8 | £50.99 upfront | 8GB data | Unlimited minutes and texts | £30pm
This EE 8GB Galaxy S8 tariff jhas been one of our faves for a while now. The balance between upfront price and monthly bills should be admired like a great work of art. Really good value, this. You also get unlimited calls and texts 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. Total cost over 24 months is £770.99

Samsung Galaxy S8 | FREE upfront | 30GB data | Unlimited minutes and texts | £32pm
Say whaaaaaaaaaaat!? Big data deals had got out of hand on the brilliant Samsung Galaxy S8. But this new tariff is an absolute cracker. The phone's bright and beautiful screen and included AKG earphones make it the ideal multimedia companion. To make the most of TV and music streaming services, you need a decent wedge of data so you can keep using away from the Wi-Fi. So here it is, the very best big data deal on the S8 as it stands. Total cost over 24 months is £768

Samsung Galaxy S8 | £79 upfront | 100GB data | Unlimited minutes and texts | £58pm
Unless you really really really need this much data, look away from Three now. It's gone from hero to zero on big data plans on the Samsung Galaxy S8, and we just can't quite understand why. But no other major network currently offers this sheer amount of data, so you don't have much choice if it's what you really need.. Total cost over 24 months is £1471

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 - so much so that the Galaxy S9 barely seems to have improved on it. 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.

The best Samsung Galaxy S8 deals on O2

Samsung Galaxy S8 | £40 upfront (with 10OFF code) | 3GB data | Unlimited minutes and texts | £23pm
This just became the cheapest way you can get the Samsung S8 on O2 right now - and by some distance. You only get 3GB of data each month, which won't suit everybody. But the monthly bills are tremendous and paying less than £600 over the two years is nothing short of spectacular. So ideal if you want a still-brilliant handset plus the benefit of O2's Priority rewards. Total cost over 24 months is £592

Samsung Galaxy S8 | FREE upfront | 16GB data | Unlimited minutes and texts | £30pm
16GB is a stack of data to stream, surf and play with, and we really like the fact that you don't have to pay anything at all upfront to get it with this Carphone Warehouse tariff. Those features, combined with the really reasonable monthly bills mean that this isn't bad at all for such a good phone. Massively cheaper than it was a week or two ago. Total cost over 24 months is £720

 The best Samsung Galaxy S8 deals on Three

Samsung Galaxy S8 | £24.99 upfront | 4GB data | Unlimited minutes and texts | £37pm
This is currently the cheapest way to buy the Galaxy S8 on Three, but it just got waaaaaaaaay more expensive. It's nowhere near to mounting a serious challenge to the other networks for sheer low prices. Total cost over 24 months is £912.99

Samsung Galaxy S8 | £49.99 upfront | 30GB data | Unlimited minutes and texts | £45pm
Wow! This is so much more expensive than what you used to be able to get on Three for 30GB of data. It used to be the network for big data deals, but has somewhat lost its mojo for the time being. Total cost over 24 months is £1129.99
