Best 4K TV Under £600 UK
The £400-£600 range is where 4K TVs get genuinely impressive in the UK market. This budget opens up QLED panels with local dimming, full HDMI 2.1 for next-gen gaming, and 55-65 inch screen sizes that properly fill a living room. You are choosing between premium features from Hisense and TCL or stepping into the entry-level ranges of Samsung, Sony, and LG.
What to Look For
- 1At this budget, insist on local dimming (also called Micro Dimming or Direct LED) — it dramatically improves contrast in dark scenes, which matters for evening viewing in the UK.
- 2HDMI 2.1 with 4K/120Hz is standard at this price — essential if you own a PS5 or Xbox Series X and want the full next-gen gaming experience.
- 3Consider 65 inches if your room allows it — the price jump from 55 to 65 inch is much smaller in this bracket than at budget level.
- 4Check for Freeview Play integration rather than just Freeview HD — Play adds 7-day catch-up scrollback directly in the TV guide.
- 5Dolby Atmos passthrough via eARC is worth checking if you plan to add a soundbar — most TVs at this price support it through at least one HDMI port.

Editor's Note
This mid-range bracket is the most competitive segment in the UK TV market. Hisense's U7 and U8 series consistently outperform their price class, while Samsung's Q60/Q70 QLED range offers the brand recognition and Tizen ecosystem many UK buyers prefer. Sony models at this price tend to prioritise picture processing over raw specs — worth it if you watch a lot of broadcast TV and films. Currys, Argos, and Amazon UK all price-match aggressively, so compare across all three before buying.
