Getting a great 4K TV for under £400 in the UK has never been more achievable. In 2026, this budget comfortably buys QLED colour technology, Dolby Vision HDR and smart platforms with Freeview HD or Freely support — features that cost £700+ just four years ago. TCL, Hisense and Samsung all compete fiercely in this bracket, delivering screens from 43 to 55 inches with modern HDMI inputs and UK-compliant energy labels. This guide covers the best Amazon UK picks under £400, all in stock with Prime delivery and full UK Consumer Rights Act protection. Key things to check at this price: whether the TV supports Freely (aerial-free live UK TV), whether HDMI 2.1 is present for gaming consoles, and what the HDR format support covers. All models here meet current UK safety standards with CE marking.
Buying guide
What to look for in 4K TVs Under £400
1Freely vs Freeview HD: Freely streams BBC, ITV, C4 and C5 over broadband — no aerial needed. Freeview HD requires a rooftop aerial. At this price, newer sets increasingly favour Freely
2HDMI 2.1 is rare under £400 but worth finding if you own PS5 or Xbox Series X — it enables 4K 120Hz gaming; HDMI 2.0 limits to 4K 60Hz
3Look for HDR10+ or Dolby Vision support — dynamic metadata formats adjust brightness scene-by-scene for better results than standard HDR10
4At 43–55 inches, VA panels dominate this price range — expect deep blacks but narrower viewing angles; position your sofa centrally for best results
5UK energy ratings now appear as an A–G scale; models in this guide rate A or B, costing around £20–35 per year at average UK electricity prices
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.
Product prices and availability are accurate as of 01 Aug, 17:42 (London time) and are subject to change. Any price and availability information displayed on Amazon.co.uk at the time of purchase will apply to the purchase of this product.

Editor's Note
All six models carry CE marking and comply with UK Electrical Equipment (Safety) Regulations 2016. The UK energy label A–G scale is your best guide to running costs: an A-rated 50-inch TV costs roughly £22/year at the current UK average tariff (28p/kWh). Freely is now the recommended live TV standard for broadband-connected UK households — it eliminates aerial installation costs and delivers BBC, ITV, Channel 4 and Channel 5 in HD over Wi-Fi. Under the Consumer Rights Act 2015, you have up to six years to claim for an inherent fault from the retailer — keep Amazon order confirmation emails. Samsung's Tizen, Fire TV and Hisense's VIDAA all include BBC iPlayer, ITVX, All 4 and My5 as standard UK apps.
Our Take
The sub-£400 4K TV market in 2026 is dominated by TCL and Hisense, and rightly so — both brands are shipping QLED panels with Dolby Vision at prices that UK retailers were charging for basic Full HD sets three years ago. The TCL T6C range is the standout story: a 55-inch QLED for £289 is genuinely astonishing. The only meaningful caveat is the lack of HDMI 2.1 across this bracket — gamers with PS5s should save up to the £400–500 range where it starts appearing.
Questions & answers
Frequently asked questions
What is the best 4K TV under £300 in the UK?
The TCL 55T6C-UK at £289 offers the best value — a 55-inch QLED 4K TV with Dolby Vision and Fire TV for under £300. For smaller rooms, the Hisense 43A6QTUK at £199 delivers Freely support and 4K with Dolby Vision for even less.
Does a budget 4K TV support Freeview HD or Freely in the UK?
Most 2025–2026 budget TVs support either Freeview HD (requiring an aerial) or Freely (requiring broadband). Hisense models in this guide include Freely built-in. TCL Fire TV models require a Freeview box or aerial for live UK TV unless the listing specifically mentions Freely.
Is QLED worth the extra cost under £400?
Yes — QLED Quantum Dot delivers significantly wider colour gamut and better brightness than standard LED LCD. At this price bracket, the difference between a QLED TCL T6C and a standard LED set is clearly visible on HDR content. If the price difference is under £50, always choose QLED.
