HDMI cables are the purest upsell in consumer technology. The shop will happily sell you a £30 "premium" cable, and the box will shout about 16K and 96Gbps, and none of it will make your television look better. Here is the number that ends the argument: a certified HDMI 2.1 cable costs £4.74, and the plain 2.0 version costs £3.99. The whole debate is worth 75 pence. These are the best HDMI cables to buy in 2026, with UK prices checked on Amazon UK on 15 July 2026.
The Short Version
- Best overall — Amazon Basics Ultra High Speed (48Gbps). Certified HDMI 2.1, does everything, at £4.74.
- Best budget — Amazon Basics High Speed (18Gbps). Fine for 4K at 60Hz, at £3.99.
- Best branded — UGREEN HDMI 2.1 Certified. Sturdier build, same certification, at £6.11.
- Best long run — Southlight 8K 5M. Five metres without dropouts, at £8.49.
- Best alternative — Snowkids 2M Certified. Another properly certified 2.1, at £6.99.
Best Overall: Amazon Basics Ultra High Speed (48Gbps)
At £4.74 this is the only HDMI cable most people ever need to buy. It carries the full 48Gbps of HDMI 2.1, which means 4K at 120Hz for a PS5 or Xbox Series X, 8K at 60Hz if you ever go there, plus VRR, ALLM and eARC for a soundbar. Crucially it is certified — the Ultra High Speed programme actually tests cables, so the label means something. Buying this instead of the £3.99 cable costs you 75p and removes every future compatibility worry. Check the price on Amazon
Best Budget: Amazon Basics High Speed (18Gbps)
Related Articles
The £3.99 Amazon Basics High Speed cable carries 18Gbps, which is enough for 4K at 60Hz — that covers every streaming service, every Blu-ray, and a PS4 or Switch. If your telly is a normal 4K set and your source is Netflix or a set-top box, this will do the job perfectly and no cable on earth will improve the picture. Buy it without guilt. Just note it will not do 4K at 120Hz, which is the one thing that pushes people to 2.1. Check the price on Amazon
Best Branded: UGREEN HDMI 2.1 Certified
At £6.11 the UGREEN is certified for the same 48Gbps as the Amazon Basics cable, supporting 4K at 240Hz, 144Hz and 120Hz plus eARC. You are paying roughly £1.40 more for a better-made connector and a sturdier jacket — worth it if the cable will be pulled in and out of a console or bent tightly behind a wall-mounted TV. It will not produce a better image than the cheaper certified cable, because that is not how digital signals work. Check the price on Amazon
Best Long Run: Southlight 8K 5M

Length is the one place where cable quality genuinely bites: past about two metres, poorly made cables start dropping out at high bandwidth. The Southlight at £8.49 is a certified 5-metre HDMI 2.1 cable rated for 8K at 60Hz and 4K at 120Hz, which is what you want for a projector or a TV across the room from the amplifier. If you need distance, buy a certified cable rather than the cheapest one on the shelf. Check the price on Amazon
Best Alternative: Snowkids 2M Certified
The Snowkids 2-metre at £6.99 is another properly certified HDMI 2.1 cable, useful when the others are out of stock or you want a specific length. Same 48Gbps ceiling, same features, same reality: certified is certified. There is no premium tier above this that does anything. Check the price on Amazon
Who Should Buy Which?
Almost everyone should buy the £4.74 certified 48Gbps cable and stop thinking about it. That is the honest answer, and it is worth 75p more than the budget option. The only reason to consciously choose HDMI 2.0 is if you already have a drawer full of them — for 4K at 60Hz they are identical in practice. You genuinely need 2.1 only if you have both a 4K 120Hz screen and a source that can drive it (PS5, Xbox Series X, or a decent gaming PC); if either half is missing, the cable changes nothing. Buy a certified cable specifically when the run is over two metres, where cheap cables actually fail. And ignore the marketing entirely: cables advertising "HDMI 2.2", "16K" or "96Gbps" for £18 are selling a specification for devices that do not exist in your living room. HDMI is digital — the signal either arrives intact or it visibly breaks up; there is no "richer colour" from a dearer wire. Sorting out a TV or soundbar too?

How to Choose an HDMI Cable
A few things actually matter. Certification is the only label worth trusting: "Ultra High Speed" is a tested programme for 48Gbps HDMI 2.1, and "High Speed" means 18Gbps HDMI 2.0 — anything else on the box is marketing. Bandwidth decides capability: 18Gbps handles 4K at 60Hz, while 48Gbps is needed for 4K at 120Hz, 4K at 144Hz or 240Hz on a gaming monitor, and 8K at 60Hz. Features ride on that bandwidth — VRR stops tearing on a console, ALLM switches the TV into game mode automatically, and eARC carries lossless audio to a soundbar; all three need HDMI 2.1 at both ends. Length is the real quality test: under two metres almost anything works, but beyond that buy certified. Finally, remember both devices must support a feature for it to work — a 2.1 cable cannot add 120Hz to a 60Hz television.
