Next update: when Openreach FTTP build notes or Virgin Media’s cable-to-fibre conversion guidance change the practical choice at typical UK postcodes.
By: Switch Editorial Team, Switch Squid Ltd
As of 28 September 2026, full fibre (FTTP) and cable broadband are not the same product: Openreach-style full fibre runs fibre to the premises with stronger upload and lower latency habits, while Virgin Media’s legacy cable network still uses coaxial copper into many homes (DOCSIS) with competitive downloads but much weaker uploads — and Virgin is converting cable areas toward full fibre over the coming years. When Openreach FTTP is live and you need the headroom, our primary Get deal path is the verified BT Full Fibre 900 affiliate offer. We may earn a commission if you order through our links.

Full fibre vs cable: what actually differs
| Topic | Full fibre (FTTP) | Cable (legacy DOCSIS HFC) |
|---|---|---|
| Last stretch | Fibre into the home / ONT | Coaxial copper into many Virgin homes |
| Download | High (hundreds of Mbps to multi-gig depending on product) | Also high on Gig1/Gig2-class products |
| Upload | Usually much stronger / nearer symmetric on many FTTP products | Often far lower on legacy cable (tens of Mbps on many gig plans) |
| Peak evenings | Generally steadier when the line is true FTTP | Street-level sharing can soften busy-hour speeds |
| Future path | Already full fibre | Virgin converting cable footprint toward full fibre over multi-year programme |
Wi-Fi still decides room-to-room feel. A 900 Mbps FTTP line into a cupboard hub will feel slow on the far sofa. Budget mesh and hub placement before you fetishise the WAN badge.
When full fibre (and BT Full Fibre 900) wins
Choose Openreach FTTP when the checker shows it live, you care about uploads (calls, cloud backup, creative files), and Year-1 cash works after setup fees and rise months. BT Full Fibre 900 is the retail path we track when you want ~900 Mbps-class Openreach fibre through the verified affiliate offer. Our 500-vs-900 October guide covers speed-tier sizing; this URL is the technology fork.
Choose BT Full Fibre 900 if Openreach FTTP fits
- Run the availability checker for the exact address first
- Compare Year-1 cash including known rise months
- Prefer FTTP when uploads and busy-hour steadiness matter
When cable still wins today
Cable can still win when Virgin is the only ultrafast option on your street, the live download price is sharper, and your household is download-heavy rather than upload-heavy. If Virgin has already moved your cabinet to true XGS-PON full fibre (Hub 5x / fibre-to-hub presentations), treat that as full fibre — not legacy cable. Ask the retailer what technology the order actually installs.
Fit summary
Good for full fibre / BT FF900: Openreach FTTP live, upload-sensitive homes, WFH backups, multi-player households.
Good for cable today: Virgin-only streets where FTTP is dark and downloads dominate your use.
Consider alternatives: CityFibre, Community Fibre, Hyperoptic and other alt-nets where they undercut retail Openreach on your postcode.
Important conditions
- Availability is premises-specific — always run the checker.
- Monthly price, activation, mesh kit and mid-contract rises must be read on the live offer page.
- Leaving fees can apply if you cease early.
- One Touch Switch helps move providers, but you still own cease/start dates.
- We will not freeze a social-media price the basket no longer shows.
Switching steps
1) Check Openreach FTTP and Virgin technology for the exact address.
2) List peak concurrent uses (calls, backups, streams, games).
3) Compare Year-1 cash for live FTTP and cable options you can actually order.
4) Factor mesh if the hub cannot sit central.
5) Order via the tracked BT Full Fibre 900 path if Openreach 900 Mbps-class is the right rung.
6) Diary rise months inside your stay.
Final decision card
Openreach FTTP live + upload-heavy home → check BT Full Fibre 900.
Virgin-only street + download-heavy use → cable can still be rational today.
Neither ultrafast → ignore badge wars until the build arrives.
Check availability for BT Full Fibre 900
- Confirm Openreach FTTP at your socket

Worked household shapes
Two WFH adults, cloud backups: FTTP upload headroom usually beats legacy cable gigabit marketing.
Evening streaming flat, light uploads: whichever live ultrafast is cheapest after rises can win — technology still matters less than Wi-Fi.
Creative freelancer uploading 20GB projects: read upload figures on the product card, not only “gigabit” labels.

Upload, latency and the “gigabit” brochure trap
Download Mbps sell the brochure; upload Mbps and latency decide video calls and cloud backups. Legacy cable products can advertise “gigabit” downloads while uploading at a fraction of that speed. Full fibre products more often publish healthier upload tiers — still read the card, because not every FTTP product is symmetric. Latency on busy cable segments can also feel soft for competitive gaming even when the speed test looks fine at 10am.
“Up to” wording on older copper products is a different conversation again. Do not compare an “up to 500 Mbps” copper claim with a full-fibre 500 Mbps product as if they were twins. Stop-sell on Openreach FTTC in FTTP areas is pushing many streets toward full fibre retail — if your cabinet is stop-sell, plan the move rather than renewing a fading copper product out of habit.
One Touch Switch, cease dates and housemate drama
UK broadband switching is smoother than the old cease-and-pray era, but you still need a named bill payer, a clear start date and a plan for router returns. If a housemate’s name is on the Virgin contract, a beautiful Openreach FTTP order will not save you from leaving-fee arguments when they move out. Fix the account name and cease plan first, then pick technology.
Student and HMO lets should also read our student-focused BT Full Fibre twin — this page stays on the technology choice for general households. Alt-nets can undercut both BT retail and Virgin on some streets; take the live network that meets upload needs at the Year-1 cash you can afford.
Price rises inside the term
Many 2026 broadband contracts still step prices in March. When you compare full fibre versus cable, build Year-1 and “months you will actually stay” cash with those steps included. A lower rung with gentler rises can beat a flashy 900 Mbps promo that jumps hard in spring. Mesh kit sold as an add-on can also erase a headline saving — include it if your layout needs it.
Alt-nets versus retail Openreach and Virgin
CityFibre, Community Fibre, Hyperoptic, toob, YouFibre and others can undercut or out-upload a retail Openreach 900 Mbps product on some streets. The full-fibre-versus-cable decision only matters inside the network you can actually order. If an alt-net offers symmetrical gigabit for less than BT’s Full Fibre 900 Year-1 cash, take the live network — do not fetishise the BT badge. Conversely, if only Openreach FTTP is live, BT Full Fibre 900 is a concrete retail path we can track through the affiliate offer on this page.
FAQ
Is full fibre better than cable in 2026?
For uploads, latency and long-term consistency, full fibre usually wins where it is live. Legacy cable can still match headline downloads on some streets.
Is Virgin Media full fibre?
Many Virgin homes are still on hybrid fibre-coaxial cable. Some areas and newer builds use true full fibre — confirm the technology on the order, not the marketing slogan alone.
Do I need BT Full Fibre 900?
Only if Openreach FTTP is available and your household needs ~900 Mbps-class headroom. Many homes are fine on mid-tier FTTP.
Will 900 Mbps fix Wi-Fi in every room?
Not by itself. Mesh and hub placement still dominate room-to-room speed.
How should I compare Year-1 cost?
Add monthly fees across the months you will stay, plus setup, any mesh, and known rise months.
What if only copper is available?
Order the best available technology and ignore full-fibre-versus-cable debates until ultrafast lands.
Do you earn commission on the BT link?
Yes. SwitchSquid may earn a commission via the tracked affiliate link at no extra cost to you.
