Need a Cat6 or Cat8 ethernet cable for a router, TV box, or desk PC without guessing length and connector type?
Start with length, category (Cat6 vs Cat8), and flat vs round jacket on amazon.co.uk, then shield claims and RJ45 fit, before you buy a 20 m coil that will not reach the socket you meant.
Last updated: 1 October 2026
Ethernet cables sit high on Amazon UK Computers charts because wired links still beat weak WiFi for gaming, streaming boxes, and home offices. This is a practical UK shortlist for length, category, and listing checks. It does not invent speed lab results, prices, or brand ratings.
Why a wired ethernet cable still matters
A short Cat6 or Cat8 lead from router to PC, console, or TV reduces dropouts when the flat is busy. Measure the path along skirting, not the straight-line distance. Flat cables tuck under rugs more easily; round cables often feel tougher for short desk runs.

- Cat8 ethernet cable UK when the listing clearly states Cat8
- flat ethernet cable UK for under-carpet routes
Open the live listing on the day you buy. Stated category, length, and shield type vary by seller.
Cat6 vs Cat8, length, and shape
Cat6 covers most UK home broadband setups. Cat8 listings often aim at short high-bandwidth runs; treat headline Gbps claims carefully and match what your router ports actually support. Buy the shortest length that covers your measured path with a little slack. Snagless RJ45 boots help when you plug and unplug often.
- Cat6 ethernet cable 2m UK for desk and TV distances
- Cat6 ethernet cable 5m UK for room-to-router runs
- Cat8 ethernet cable 1m UK for short patch leads when Cat8 is stated
- Prefer listings that state metres in plain text, not only a photo of a coil
Ignore vague “gaming ultra speed” titles with no category or length.
Shielding, outdoor use, and fit
Indoor patch cables suit most flats. Outdoor or buried runs need weather-rated jackets, which are a different search. Check that both ends are standard RJ45 for your router and device. If you use a slim laptop USB-C dock, confirm you need a cable into the dock’s ethernet port, not a magical wireless claim on the cable page.

- Keep bend radius gentle behind furniture so the jacket does not crease hard
If the listing never states Cat6 or Cat8 and length, check the photos and Q&A carefully before you buy.
