Broadband marketing loves a big speed number, but the fastest package on the page isn't automatically the right choice for every household. Working out how much speed you genuinely need — based on how many people are online at once, what you're doing, and how many devices are connected — will usually save you money compared with defaulting to the fastest available tier.
1. Full fibre vs cable vs FTTC
Full-fibre (sometimes called FTTP) connections run fibre-optic cable all the way to your property, generally offering the fastest and most consistent speeds, particularly for uploads. Cable broadband, delivered by Virgin Media over its own network, can also reach very high download speeds, though upload speeds are often more limited than full fibre. FTTC (fibre to the cabinet) connections, still common in areas without full fibre, run fibre to a local street cabinet and then copper the rest of the way to your home, which caps the maximum speed achievable compared with full fibre or cable.
2. How much speed do you actually need?
- A single person or couple, mostly browsing and streaming one device at a time: a standard fibre package is usually plenty.
- A busy household with several people streaming, gaming and video calling simultaneously: a faster full-fibre tier reduces the risk of everything slowing down at once during peak evening hours.
- Home workers uploading large files or on frequent video calls: upload speed matters as much as download speed here, which is where full fibre tends to have a clear advantage over FTTC and even some cable packages.
3. Gigabit broadband: do you need it?
Gigabit-capable packages advertise extremely high theoretical speeds, but very few everyday activities actually require anywhere near that much bandwidth simultaneously. Unless you have an unusually large household with many people doing bandwidth-intensive tasks at the same time, or you specifically need very fast large file transfers for work, a mid-tier full-fibre package will often deliver a smooth experience for a lower price. Compare this against our guide to the cheapest broadband deals to avoid overpaying for speed you won't use.
4. Latency matters for gaming and video calls
Download speed isn't the whole story — latency (often shown as "ping") affects how responsive a connection feels for online gaming and video calls. Full-fibre connections generally offer lower, more consistent latency than older FTTC connections, which can matter more than an extra 100Mbps of download speed if gaming or video conferencing is a priority in your household.
5. Checking availability at your address
The fastest tiers, particularly full fibre and gigabit packages, aren't available everywhere yet. Providers like BT, Sky and full-fibre altnets such as YouFibre and Zen Internet have different rollout footprints, so always check what's actually available at your specific address rather than assuming the fastest advertised speed applies everywhere.
6. Frequently asked questions
Is full fibre always faster than cable?
Not necessarily for downloads, where cable can also reach high speeds, but full fibre generally offers a clear advantage for upload speeds and tends to have more consistent latency.
Do I need gigabit speed for a family of four?
Usually not, unless several people are simultaneously doing very bandwidth-intensive tasks like 4K streaming, large downloads and video calls all at once. A solid mid-tier full-fibre package is often enough for typical family usage.
Why does upload speed matter?
Upload speed affects video calls, cloud backups, and uploading large files — activities that have become far more common with remote working. If you regularly do any of these, prioritise a connection with strong upload speeds, not just fast downloads.
How do I check what speeds are available at my address?
Use an availability checker for your specific postcode, since full fibre, cable and FTTC coverage all vary significantly by location, even within the same town.
7. Conclusion
The fastest broadband deal isn't automatically the best one for your household — work out how many people and devices are typically online at once, whether upload speed matters for your work, and compare that against the live speed tiers above before paying a premium for capacity you won't use.
