💡 More than 5 devices? Full fibre is worth serious consideration.

💡 Regular home working is one of the strongest reasons to upgrade.

Significantly Faster Speeds — Consistently

Full fibre delivers speeds from 100Mbps up to 1Gbps+ — far beyond what ADSL or FTTC can offer. More importantly, these speeds are consistent. Unlike copper-based connections that degrade with distance from the cabinet or exchange, fibre optic cables deliver the same speed regardless of how far you are from the nearest infrastructure point.

Much Better Upload Speeds

ADSL and FTTC connections are asymmetric — download speeds are prioritised and upload speeds are often only a fraction of the download. Full fibre offers dramatically improved upload speeds, which makes a real difference for video calls, cloud backups, uploading large files, content creation, and remote desktop connections. If you work from home this alone can justify the switch.

Handles More Devices Without Slowing Down

The average UK home now has over 10 connected devices — phones, tablets, laptops, smart TVs, games consoles, smart speakers, doorbells, and more. Full fibre's higher bandwidth means all of these can run simultaneously without competing for the same limited connection. Evening slowdowns caused by everyone in the household going online at once become a thing of the past.

More Reliable — Less Affected by External Factors

Copper cables are susceptible to electrical interference, moisture ingress, and physical degradation over time — all of which can affect connection quality and cause intermittent dropouts. Fibre optic cables are immune to electrical interference and far more durable, resulting in a more stable and reliable connection day to day. Fewer unexplained dropouts, fewer calls to your provider.

Future-Proofing Your Home Connection

The UK copper network is being decommissioned. BT Openreach has a rolling programme to retire copper infrastructure as full fibre becomes available in each area. At some point your existing copper-based connection will no longer be an option — switching to full fibre now, on your own terms and timeline, is better than being forced to switch later, potentially under time pressure.

Prices Have Come Down Significantly

When full fibre first became available it commanded a significant premium over standard broadband. That gap has narrowed considerably as more providers have entered the market and competition has increased. In many areas, entry-level full fibre packages are now priced comparably to mid-tier FTTC packages — meaning the speed and reliability gains come at little or no extra monthly cost.

Full Fibre Isn't Available at Your Address Yet

Despite rapid rollout across the UK, full fibre is still not available everywhere — particularly in rural and semi-rural areas. If it's not yet available at your postcode there's simply nothing to upgrade to right now. Check the Ofcom coverage checker and your current provider's availability tool. If rollout is planned for your area, you may only need to wait a few months — it's worth asking your provider for an estimated date.

You're Mid-Contract With Early Exit Fees

If you're locked into a current broadband contract with significant time remaining, the early exit fees could outweigh the benefits of switching immediately. Calculate what you'd pay to exit early versus waiting until your contract ends naturally. In most cases waiting a few months until your contract end date is the financially sensible approach — and gives you time to research the best full fibre deal properly.

Your Current Speed Is Already Sufficient for Your Needs

If you're a single or two-person household with light internet usage — basic browsing, occasional streaming, video calls — and your current speed test results are consistently above 30Mbps, you may genuinely not notice a significant difference with full fibre in day-to-day use. Upgrading for its own sake when your current connection meets your needs comfortably is unlikely to improve your experience meaningfully.

You're Planning to Move Home Soon

Signing a new 24-month full fibre contract when you're planning to move within the next year could leave you paying early exit fees or trying to transfer a contract to a new address — which isn't always possible, particularly if you're moving to an area served by a different network provider. If a move is on the horizon within 12 months, it may be worth waiting and choosing your new connection once you know your new address.

The Price Difference Is Still Significant in Your Area

While full fibre pricing has come down considerably in many areas, there are still parts of the UK where the price gap between a standard FTTC package and an equivalent full fibre package is substantial — particularly in areas with fewer competing providers. If the monthly cost difference is meaningful to your budget and your current speeds are adequate, it's entirely reasonable to wait until the price becomes more competitive in your area.

✅ Upgrade now if:

• Full fibre is available at your address
• Your contract is ending soon or already ended
• You regularly experience slow or inconsistent speeds
• You work from home or have a busy household
• The price difference is minimal

⏳ Wait if:

• Full fibre isn't available at your postcode yet
• You have significant contract time remaining
• Your current speeds comfortably meet your needs
• You're planning to move home within 12 months
• The price jump is too significant right now

The oldest widely available technology, delivered entirely over copper telephone lines. Speed is heavily affected by distance from your local exchange. If you're on ADSL, you're on the slowest mainstream connection available in the UK today.

Fibre to the Cabinet — the most common broadband type in the UK. Fibre runs from the exchange to the green street cabinet, then copper from the cabinet to your home. Speed still varies depending on how far your property is from the cabinet.

Single Order Generic Ethernet Access — similar performance to FTTC but doesn't require a traditional phone line. It's the broadband-only version of FTTC and increasingly common as the UK moves away from copper voice services. Speeds are broadly the same as FTTC.

Fibre to the Premises — pure fibre optic cable runs directly from the exchange into your home. No copper in the chain means no distance-related degradation, no interference, and consistent speeds at all times of day. This is the UK government's target technology for the majority of UK homes.
