Amazon now sells four different Fire TV Sticks in the UK at the same time — HD, 4K Select, 4K Plus and 4K Max — often within a few pounds of each other, with overlapping names carried over from older generations still on sale. The honest answer to “which one do I need” rarely comes from a spec sheet. It comes from what has actually gone wrong for people who bought the wrong one. Here is that guide, organised by the regret, not the resolution.
The current UK lineup, in plain terms
Four sticks, four rough tiers:
- Fire TV Stick HD — the cheapest, no 4K, fine for an older TV or a bedroom set.
- Fire TV Stick 4K Select — the newest, cheapest 4K option, and the one with the most caveats below.
- Fire TV Stick 4K Plus — the renamed former “4K” stick, now positioned above the Select.
- Fire TV Stick 4K Max — the fastest of the four, aimed at bigger screens and heavier multitasking.
Reviewers have pointed out that Amazon renamed the old “4K” stick to “4K Plus” specifically to stop it being confused with the new “4K Select” — and that the two names are still, in practice, confusing anyone shopping in a hurry.
“My TV is not 4K” — stop reading spec sheets
If your television is not a 4K set, none of the 4K sticks will show you a 4K picture, whatever the box says. UK buyers have posted in forums after realising they paid extra for 4K capability their television physically cannot display. Check your TV’s own resolution first (its settings menu or manual will say 1080p, Full HD, or 4K/UHD) and buy the HD stick if it is not 4K. That single check saves more money than any other decision on this page.
“I want to run IPTV apps or sideload anything” — read this before you pay
This is the question that matters most for FirestickUK visitors, and it is the one Amazon’s own product pages do not answer clearly. Amazon has begun shipping some new, cheaper Fire TV Stick models on Vega OS, a completely different operating system to the Android-based Fire OS every earlier stick used. Vega OS does not support sideloading or the Downloader app at all — not a locked-down version of it, none of it. If installing IPTV apps, Downloader, or any app from outside the Amazon Appstore matters to you, that single fact matters more than 4K, RAM, or price. See our full Vega OS compatibility guide for exactly which current models are affected and how to check before you buy.
“I have two TVs” — this is not a hardware question
Buying two identical sticks does not automatically mean you can watch two different channels on two TVs at the same time on one IPTV subscription — that depends on your subscription’s simultaneous-connection allowance, not the device. See our multi-room IPTV guide before assuming a second stick is all you need.
“I already own an older Firestick” — do you actually need to upgrade?
If your current stick still runs your apps without constant crashing or unbearable lag, there is rarely a good reason to replace it purely because a newer model exists. The people who benefit most from upgrading are those on a genuinely old, slow 2nd-generation stick, or those who have just discovered their current stick cannot do something they now need — most commonly 4K playback or extra storage for more apps.
The 4K Select’s real trade-offs
The 4K Select is the newest, cheapest way into 4K — but early UK reviews have flagged a genuine list of compromises: no VPN app available at launch, gaps in the live TV guide compared to other models, less RAM than the Plus or Max, and a Micro-USB power connector rather than USB-C. None of these make it a bad device outright, but they are exactly the kind of detail that only shows up after the box is opened, not on the shelf.
How to check whether a stick is Vega OS before you buy it
Amazon does not currently label Vega OS clearly at the point of sale in the UK store. The most reliable check is the model name and generation year together — our Vega OS tracker is kept up to date with exactly which current listings run which operating system, since this changes as Amazon expands the rollout.
Frequently asked questions
What is the actual difference between the 4K Plus and the 4K Max?
The Max is built for faster app switching and better performance on bigger, more demanding TVs; the Plus covers the same 4K playback for most people at a lower price. Neither difference matters if your TV is not 4K in the first place.
Do I need a 4K stick if my TV is not 4K?
No. A 4K stick cannot make a non-4K television display a 4K picture. Buy the HD model and put the saving toward your subscription or a second device instead.
Will my existing, older Firestick stop working in 2026?
There is no confirmed evidence that Amazon is forcing existing Fire OS devices onto Vega OS retroactively. The Vega OS rollout so far applies to new hardware, not a forced update pushed to sticks already in people’s homes — but this is Amazon’s current stated approach, not a guarantee, so it is worth checking our Vega OS tracker periodically rather than assuming.
Which model should I buy if I only care about IPTV and do not care about 4K?
The Fire TV Stick HD is normally the simplest, cheapest choice — provided it is confirmed to be running Fire OS rather than Vega OS at the time you buy it, since sideloading is what most IPTV setups depend on.
