The short answer
Our top pick for 4K TVs Under £300 in the UK is the TCL 55PF650K 55-inch 4K Ultra HD, HDR TV, Smart LED Fire TV (Dolby Vision, Dolby Atmos, DTS, HDR 10, Alexa built-in, Airplay2, Miracast).
The TCL 55PF650K gives you the largest screen in this guide while staying under £300, and its Fire TV platform pulls Netflix, Prime Video, Disney+ and Freely into one interface with Alexa built in.

You can get a genuinely good 4K TV for under £300 in the UK, and the choice at this price is better than it has ever been. We've compared five popular models on Amazon UK — from compact 43-inch sets to a 55-inch big-screen option — looking at screen size, smart platform, HDR support and brand reliability. Brands like Hisense, TCL and LG now compete hard in the budget bracket, and the gap between a cheap TV and a mid-range one has narrowed considerably. This guide focuses on what you actually get for your money rather than marketing buzzwords, so you can match the right panel size and platform to your room and how you watch.
Buying guide
What to look for in 4K TVs Under £300
1Screen size is the single biggest decision at this budget. Under £300 you can comfortably fit a 43-inch set for a bedroom or study, a 50-inch for a typical living room, or stretch to a 55-inch for a bigger space. As a rough guide, sit around 1.5 to 2.5 times the screen's width away for 4K content, so a 55-inch TV suits a sofa roughly 2 metres back. Bigger is usually the better value here — the price jump from 43 to 50 inches is often small — but only if your room and viewing distance can take it.
2The smart platform matters more than the spec sheet suggests, because it's what you'll interact with every day. Fire TV (TCL), Freely (Hisense) and webOS (LG) each bundle the major UK apps — BBC iPlayer, Netflix, Disney+, YouTube and Prime Video — but they differ in layout, speed and how much advertising sits on the home screen. Hisense's Freely models let you stream live UK channels over the internet without an aerial, which is genuinely useful for rooms with poor reception. Samsung's Tizen OS also appears on some third-party sets.
3Check the HDR format, not just whether HDR is listed. Dolby Vision (found on the Hisense 43-inch and the TCL) adjusts brightness and contrast scene by scene and tends to look noticeably better than basic HDR10 on Netflix and Disney+. That said, most budget panels can't get bright enough to show HDR at its best, so treat it as a bonus rather than the deciding factor. Panel type matters too — a QLED layer (as on the HYE set) can improve colour vibrancy, while a direct-lit LED backlight generally gives more even brightness than edge-lit alternatives.
4For gaming and sport, look at the refresh rate and processing. Most TVs at this price run a 60Hz panel, which is fine for console gaming at 60fps and everyday viewing, but you won't get the 120Hz smoothness of pricier sets. Features like AI motion processing help with fast sport, though they can introduce a soap-opera effect some viewers dislike — it's usually easy to turn off. If you game on a PS5 or Xbox Series X, check for a low-latency game mode before buying.
5Finally, weigh brand support against the headline price. Hisense, TCL and LG are established in the UK with proper warranties, spare parts and repair networks; lesser-known brands can undercut them but may be harder to get serviced if something goes wrong. A recognised brand a little higher up this bracket is often the safer buy than an unknown one at the very bottom of it, unless the saving really matters to you.
Our process
How we choose our picks
We don’t lab-test products ourselves. Instead we synthesise the strongest independent evidence — current Amazon UK listings, verified-buyer feedback, published specs and UK pricing — into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We only shortlist products actively listed and in stock on Amazon UK, checked against live catalogue data — not last year’s models.
Publicly visible buyer feedback
We look at how each product is received by UK shoppers — its overall rating standing and the praise or complaints that recur in public reviews — rather than relying on a single reviewer’s opinion.
Published specs & value
We compare manufacturer specifications, typical UK price bands, warranty and running costs so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage, plug/fitting standards, CE/UKCA marking and Consumer Rights Act cover — details that generic global lists miss.
TCL 55PF650K 55-inch 4K Ultra HD, HDR TV, Smart LED Fire TV (Dolby Vision, Dolby Atmos, DTS, HDR 10, Alexa built-in, Airplay2, Miracast)
The TCL 55PF650K gives you the largest screen in this guide while staying under £300, and its Fire TV platform pulls Netflix, Prime Video, Disney+ and Freely into one interface with Alexa built in. Dolby Vision and Dolby Atmos are welcome extras at this price, though the panel — like all budget sets — won't reach the brightness of pricier TVs. For most living rooms it's the standout big-screen value here.

Hisense 50" 50E6QTUK 4K Ultra HD Smart TV AI TV - 4K UHD, Hi-View AI Engine, Precision Colour, AI Smooth Motion, Sports Mode with Freely, Disney +, YouTube, Netflix
The Hisense 50E6QTUK is arguably the best all-round value here: a 50-inch 4K panel from a well-supported UK brand for well under £300. The Freely platform is a genuine draw if your aerial reception is poor, and the direct-lit backlight helps with even brightness. It's the size most people should buy for a standard living room without overspending.

Hisense 43" 43A6QTUK 4K Ultra HD Smart TV AI TV - 4K UHD, Hi-View AI Engine, Precision Colour, AI Smooth Motion, Sports Mode with Freely, Disney +, YouTube, Netflix
The 43-inch 43A6QTUK is the pick if you want a smaller Hisense with Dolby Vision — something the larger 50-inch model in this guide doesn't list. It's a tidy 4K set for a bedroom or second room, with the same Freely platform and Hi-View upscaling. Only step down to this size if your room genuinely calls for it, as the 50-inch offers better value per inch.

This 2025 LG delivers the polished webOS experience and reliable brand support in a compact 43-inch 4K set. The α7 AI Processor Gen8 and Filmmaker Mode are nice touches, and dual Google Cast and AirPlay 2 support make casting easy whatever phone you own.

HYE TV - Smart TV, 43" Screen Size, 4K Resolution, QLED Technology, Apple AirPlay, Samsung Tizen OS & Gaming Hub, Versatile Connectivity, Black, Perfect For Streaming, Gaming & Entertainment
The HYE set is the budget entry point here, pairing a QLED panel and Samsung's Tizen OS with the lowest price in the guide. The Gaming Hub, generous port selection and AirPlay support are unusual at this level. The trade-off is a less familiar brand with a thinner UK support network, so buy this if the saving matters more than the reassurance of a big-name badge.

Honourable Mentions
Larger-screen models above £300 — If you can stretch the budget slightly, 55-inch sets from Hisense and TCL with brighter panels and Dolby Vision open up — worth a look if your room can take the extra size.
Editor's Note
Hisense and TCL dominate the sub-£300 bracket on Amazon UK and are frequently discounted during Prime Day and Black Friday, so it's worth watching prices if you can wait. Freely-equipped Hisense sets are a smart pick if you don't have a working aerial, since they pull live UK channels over the internet. Whatever you buy at this price, plan to spend a few minutes turning off the aggressive motion smoothing and switching the picture mode away from the punchy 'Vivid' default for a more natural image.
Our Take
Under £300, you're buying a very capable everyday TV rather than a home-cinema centrepiece — set expectations around screen size and smart features rather than reference-grade picture quality. The best value usually comes from going as large as your room allows with a trusted brand, which is why the 50-inch Hisense and 55-inch TCL stand out here. If budget is genuinely tight, a smaller 43-inch set from Hisense or LG still gets you real 4K and all the major UK apps without compromise on the essentials.
Questions & answers
Frequently asked questions
Is a 4K TV under £300 worth buying in the UK?
Yes. Budget 4K TVs from Hisense, TCL and LG now offer genuine 4K resolution, HDR support and all the major UK streaming apps for under £300. You won't get the brightness or 120Hz gaming of premium sets, but for everyday viewing and console gaming at 60fps they represent strong value.
What size 4K TV can I get for under £300?
Under £300 you can buy a 43-inch set for a bedroom, a 50-inch for a typical living room, or stretch to a 55-inch big-screen model. The price gap between sizes is often small, so it's usually worth going as large as your room and viewing distance sensibly allow.
Which is the best smart platform on a budget 4K TV?
It comes down to preference. Fire TV (TCL) is app-rich but pushes Amazon content; webOS (LG) is fast and clean; and Freely (Hisense) adds live UK channels over the internet with no aerial. All three carry BBC iPlayer, Netflix, Disney+, YouTube and Prime Video.
Do cheap 4K TVs support Dolby Vision?
Some do. In this guide the TCL 55PF650K and the Hisense 43A6QTUK list Dolby Vision, which adjusts HDR scene by scene for better contrast on compatible content. Others rely on standard HDR10. Because budget panels can't get very bright, Dolby Vision is a nice bonus rather than a deal-breaker at this price.
