The Ultimate Guide to FTTC Broadband in 2026

FTTC (Fibre to the Cabinet) runs optical fibre from the telephone exchange to a street-side cabinet, then uses the existing copper phone line for the final section to your home. This limits maximum speeds to around 80 Mbps download and 20 Mbps upload. FTTP overtook FTTC in active UK connections in Q3 2025, with 11.56 million FTTP vs 10.60 million FTTC connections. FTTC remains available from BT, Sky, TalkTalk, and Plusnet but is no longer the recommended technology for new broadband connections.

How FTTC Broadband Works

In an FTTC setup, optical fibre runs from the local telephone exchange to a green street cabinet located on or near your street — typically within 500 metres of your home. From the cabinet, the existing copper telephone wire (already in the ground) carries the signal from the cabinet to your master socket. This hybrid fibre-copper architecture is formally called VDSL2 (Very High-Speed Digital Subscriber Line 2). Openreach operates the UK's FTTC network, and multiple ISPs including BT and Plusnet wholesale access to offer FTTC broadband to customers. FTTC covers approximately 95% of UK premises — broader than FTTP at 78%.

FTTC Speeds: What to Expect in 2026

FTTC speed is highly dependent on your distance from the street cabinet. At under 100 metres, speeds of 70–80 Mbps download and 18–20 Mbps upload are achievable. At 500 metres, this drops to 40–50 Mbps download. Beyond 800 metres, speeds can fall below 20 Mbps — more like ADSL than modern broadband. FTTC is sold in two tiers: Superfast 1 (up to 36 Mbps average) and Superfast 2 (up to 67 Mbps average) by most providers. TalkTalk and Sky continue to sell FTTC packages from around £24–£30/month, typically on 24-month contracts. Average UK broadband speed in 2025 was 223 Mbps — demonstrating how far behind FTTC now sits relative to the market.

FTTC vs FTTP: The Key Differences

FTTP (Fibre to the Premises) replaces the copper section entirely, running optical fibre all the way to your home. This delivers speeds of 100 Mbps to 10 Gbps, with no distance degradation, lower latency (typically 5–12 ms vs 10–30 ms for FTTC), and significantly higher upload speeds (50–1,000 Mbps vs 8–20 Mbps for FTTC). FTTP overtook FTTC as the dominant UK broadband technology in Q3 2025, with 11.56 million FTTP connections versus 10.60 million FTTC. Prices are broadly comparable — FTTP 150 Mbps packages start from around £26/month, not significantly more than FTTC Superfast 2.

Should You Still Sign Up for FTTC in 2026?

With FTTP available to 78% of UK premises and prices at parity with FTTC, signing up for a new FTTC contract in 2026 is rarely advisable. FTTC packages lock you into a technology that is being actively replaced — Openreach plans to retire FTTC infrastructure in areas where FTTP is available over the coming years. If FTTP is available at your address, a 24-month FTTC contract means you are tied to a slower, less future-proof product until 2028. The only valid reason to choose FTTC is if FTTP is genuinely unavailable at your address — in which case FTTC is a reasonable interim option until your area is upgraded.

Frequently Asked Questions

Is FTTC the same as fibre broadband?

FTTC is marketed as fibre broadband by providers, but it uses copper wire for the final section to your home. Only FTTP (Full Fibre) uses optical fibre all the way to your property. Ofcom now requires providers to distinguish between part-fibre (FTTC) and full fibre (FTTP) in their advertising.

Why does my FTTC speed vary at different times of day?

FTTC speeds drop during peak evening hours (6–9pm) due to network congestion at the cabinet level. Multiple households share the same cabinet capacity, and when all are online simultaneously, throughput per customer decreases. FTTP does not suffer from this limitation in the same way.

Is FTTC being switched off?

Openreach has announced plans to retire FTTC infrastructure progressively in areas where FTTP is available, starting from the late 2020s. No firm nationwide switch-off date has been announced, but customers in fully-fibred areas should expect migration notices from their providers before 2030.
