TL;DR: Fibre Broadband Explained: FTTC vs FTTP and What It Means for You. First move: check your contract end date and whether you qualify for a social tariff before switching.
When providers say “fibre broadband”, they might be talking about two completely different things. Get this wrong and you could end up with speeds nowhere near what you expected.
The two types of fibre
FTTC (fibre to the cabinet)
This is where fibre runs from the telephone exchange to one of those green boxes you see on residential streets. From there, your old copper phone lines do the final leg to your home. Straightforward in theory, but there’s a catch: copper’s slower than fibre, so the further you live from that cabinet, the slower your connection gets. Live right next to it and you might hit 80 Mbps. Live 200 metres away and you’re looking at 30-40 Mbps. It’s a bit of a lottery depending on your street.
You’ll see FTTC called “superfast broadband” or VDSL. It covers about 96% of UK premises, which is why most people still have it. You’re looking at around 80 Mbps download and 20 Mbps upload as the theoretical maximum.
FTTP (fibre to the premises)
This is the proper full fibre setup. Fibre cables run all the way from the exchange into your property. No copper involved in the final stretch, which means distance becomes irrelevant. You get the same speed whether you’re 10 metres or 10 kilometres away. That’s the real difference.
FTTP (sometimes called full fibre, ultrafast broadband, or FTTH) is now available to about 82% of the UK and growing. Depending on your package, you’re looking at 100 Mbps up to 1 Gbps or more. The upload speeds are much better too, often matching your download speed.
Speed comparison
| Connection Type | Download Speed | Upload Speed | How Consistent? |
|---|---|---|---|
| Standard ADSL | 10-17 Mbps | 1 Mbps | Variable |
| FTTC | 35-80 Mbps | 10-20 Mbps | Depends on distance |
| FTTP | 100-1000+ Mbps | 50-1000+ Mbps | Very consistent |
The advantage with FTTP is that consistency you get. You’re paying for a certain speed and you’ll actually get it, time after time.
Checking what’s available at your address
Start with Openreach’s checker (or your provider’s website). Pop your postcode in and you’ll find out whether FTTP has reached you yet, what FTTC speeds you could get, and who can actually serve your address.
If you’re in a Virgin Media postcode, they’ve got their own cable network which performs similarly to FTTP anyway. Most of the other providers (BT, Sky, TalkTalk, Vodafone, Zen and loads of smaller local companies) all offer FTTP where it’s available.
What’s the installation like?
FTTC is generally painless. You’ll get a new router in the post, plug it into your existing phone line, and a few days later you’re live. No engineer visit required in most cases.
FTTP is a bit more involved because an engineer has to physically run fibre cable to your property. They’ll either drill a small hole or run it through existing ducts, then install a small box on your wall or inside your home. The actual installation appointment takes about an hour or two. If you’re renting, it’s worth checking with your landlord first just to be safe (though they can’t unreasonably refuse).
Is FTTP worth paying extra?
You’re usually looking at an extra £5 to £15 per month for FTTP compared to FTTC. Whether that’s worth it depends on your setup and what you actually do online.
Go for FTTP if you’ve got multiple people working from home, someone’s streaming 4K content on several devices at once, you’re regularly uploading large files, or you just want the peace of mind that comes with a properly reliable connection.
FTTC is probably fine if you’re doing light stuff like browsing and email, it’s just you and maybe one other person in the household, money’s tight, or you’re happy with speeds in the 50-80 Mbps range. The average household runs through about 400-500 GB per month anyway. Both FTTC and FTTP handle that easily. The real edge FTTP has is future-proofing and genuine reliability.
Common questions
How do I know if I’ve actually got fibre? Look at your router. If it plugs into a standard phone socket, you’ve got FTTC. If there’s a separate small box on the wall outside with a proper fibre cable going into it, you’ve got the real deal (FTTP).
Why isn’t FTTP available where I live? Rollout takes time and money. Openreach and other companies are building network by network, street by street. Some areas have planning issues or tricky geography that slows everything down.
Should I hold out waiting for FTTP? Not if FTTC meets your needs today. The rollout could take years in some areas. Get what’s available now and you can always upgrade later.
Do I need a phone line for FTTP? Nope. FTTP is internet only. If you don’t want a landline, you don’t have to pay for one.
What about upload speeds? This is where FTTP really shines. You’ll often get symmetric speeds (same upload as download) or at least something much better than the 20 Mbps you might get with FTTC. Makes a real difference if you’re on video calls or uploading backups regularly.
Future-proofing your connection
FTTP can theoretically handle 10 Gbps or more. The cable itself isn’t the bottleneck. As equipment improves over time, your connection can get faster without anyone having to dig up your street again.
FTTC is basically at its ceiling. Copper’s limitations mean speeds aren’t going anywhere new.
If you’re buying or you’ve settled somewhere long-term, FTTP’s the better bet. If you’re renting for a couple of years, FTTC does the job without all the installation fuss.
