The best Samsung Galaxy S8 deals in August 2018

The last few weeks have seen turbulent times for Samsung Galaxy S8 deals. One minute they're the cheapest they've ever been and we implore you to pick one up. The next, the price shoots up and they're not much cheaper than the Samsung Galaxy S9.

Well we're somewhere towards the latter at the moment. The upfront spend on our favourite 1GB and 4GB Vodafone tariffs and 3GB O2 tariff have just headed north, meaning that the cheapest S8 deals are now over £50 more expensive in a lot of cases. You can still get it for less than £20 per month, mind.

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 9 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 (with DEAL20 code) | 1GB data | Unlimited minutes and texts | £18pm
Lovely stuff. £18 per month is obviously fantastic for a phone that's still as good as the Samsung Galaxy S8, as long as you can cope with the 1GB data limit. And now that the upfront cost has been slashed again, it comes back down to less than £500 for the two year term. You'll need to remember to use the DEAL20 promotional code at the checkout, though. Sigh. Total cost over 24 months is £497

Samsung Galaxy S8 | £59.99 upfront | 4GB data | Unlimited minutes and texts | £23pm
Carphone Warehouse and the other retailers under its umbrella have been clearing up of late with their 4GB Galaxy S8 deal. That amount of data from Mobiles.co.uk is relatively good and will suit a lot of smartphone users. It remains an easy choice for our current Editor's Pick slot, especially as the price just fell by about £50. Total cost over 24 months is £611.99

Samsung Galaxy S8 | FREE upfront | 20GB data | Unlimited minutes and texts | £31pm
This just overtook the lot as our favourite EE Galaxy S8 tariff with a bigger data allowance. The price has been around for a while, but was offering only 8GB of data each month. That's been bumped up now by Affordable Mobiles to a bountiful 20GB, and there's no need to pay anything upfront either. Total cost over 24 months is £744

Samsung Galaxy S8 | FREE upfront | 25GB data | Unlimited calls and texts | £37pm
This is an absolutely exceptional S8 deal from Mobile Phones Direct, but just requires a bit of work from your side. That's because there's an epic £252 cashback available, which you get your hands on by claiming it in five instalments over the course of the two year contract. That makes the effective monthly payments £26.50 a go, and there's nothing to pay at all upfront. Total cost over 24 months is £636 (after cashback)

Samsung Galaxy S8 | £49 upfront | 100GB data | Unlimited minutes and texts | £46pm
This may look expensive, but the Samsung s8 deal on Three just took an extraordinary £300 price drop, thanks to big cuts on the monthly bills and upfront spend. Plus, no other major network currently offers this sheer amount of data. But do you really need 100GB a month? If not, we suggest you look for something else. Total cost over 24 months is £1153

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 EE

Samsung Galaxy S8 | £52.99 upfront | 4GB data | Unlimited minutes and texts | £25pm
One of the cheapest ways you can buy the Samsung Galaxy S8 on EE at the moment, and you get a decent 4GB of data from retailer Mobile Phones Direct. It costs only £25 per month and a perfectly reasonable amount upfront. Total cost over 24 months is £652.99

The best Samsung Galaxy S8 deals on O2

Samsung Galaxy S8 | £80 upfront (with DEAL20 code) | 3GB data | 1000 minutes | Unlimited texts | £23pm
It's a close run thing between this S8 deal and the best 4GB offering on Vodafone for our king of the hill. This one is a bit more expensive upfront at the moment, and gets you less data each month as well. But at least you'll be on O2's Priority rewards. Total cost over 24 months is £632

Samsung Galaxy S8 | FREE upfront | 30GB data | Unlimited minutes and texts | £36pm
30GB data deals from O2 on the Galaxy S8 just got great again. Free upfront is a great start, although the high-ish monthly bills are a bit more expensive than we would have liked. Total cost over 24 months is £864

Samsung Galaxy S8 | £19.99 upfront | 60GB data | Unlimited minutes and texts | £42pm
Crank the data allowance all the way up to a massive 60GB, and this Vodafone Galaxy S8 deal is among the most affordable. We can't quite imagine how you'd come close to using up 60GB (are you sure 30GB wouldn't be enough?), but paying around £40 a month for the privilege isn't bad at all. Total cost over 24 months is £1027.99

 The best Samsung Galaxy S8 deals on Three

Samsung Galaxy S8 | £9.99 upfront | 4GB data | Unlimited minutes and texts | £33pm
This is currently the cheapest way to buy the Galaxy S8 on Three, and it just got waaaaaaaaay cheaper. It's still nowhere near to mounting a serious challenge to the other networks for sheer low prices however. Total cost over 24 months is £801.99

Samsung Galaxy S8 | £83.99 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 £1163.99
