What Is Superfast Broadband? (2026)

Superfast broadband is defined by Ofcom as any connection delivering download speeds of 30 Mbps or above. In practical terms, this includes most FTTC (Fibre to the Cabinet) connections and all FTTP (Full Fibre) packages. As of early 2026, superfast broadband coverage reaches 97% of UK premises. However, with average UK broadband speeds at 223 Mbps, the superfast threshold is now considered a minimum standard rather than a measure of good performance.

The Official Ofcom Definition of Superfast

Ofcom defines superfast broadband as a connection capable of delivering download speeds of at least 30 Mbps. This threshold was set in 2012 and has remained unchanged, even as the average UK broadband speed grew from around 36 Mbps in 2015 to 223 Mbps in 2025. The EU has a comparable definition of 30 Mbps for NGA (Next Generation Access) networks. BT markets its FTTC Superfast 1 package as delivering an average of 36 Mbps and Superfast 2 at 67 Mbps. Plusnet uses the same Openreach infrastructure for its Unlimited Fibre (36 Mbps average) and Unlimited Fibre Extra (67 Mbps average) products.

Which Technologies Count as Superfast?

Technologies meeting the 30 Mbps superfast threshold include FTTC (36–80 Mbps), FTTP (100 Mbps to 10 Gbps), cable (Virgin Media, 50 Mbps to 2 Gbps), and most 5G home broadband connections (100–300 Mbps typical). ADSL — with maximum speeds of around 24 Mbps — does not qualify as superfast. Sky and TalkTalk both offer FTTC superfast packages from around £24/month. Ofcom's Connected Nations reports track superfast coverage separately from gigabit coverage, reflecting that 30 Mbps is no longer synonymous with high-quality broadband.

Is Superfast Fast Enough in 2026?

At 30 Mbps, a connection supports: HD Netflix (1 stream at 5 Mbps), multiple simultaneous video calls at 720p, online gaming, and general browsing. For a household of one or two people with moderate usage, 30–67 Mbps (FTTC Superfast 2) is functional. However, for households of three or more, with 4K streaming, multiple simultaneous video calls, or home workers, the 30 Mbps floor is insufficient. Ofcom's own household guidance suggests 100–200 Mbps for a busy household. The Universal Service Obligation guarantees only 10 Mbps — meaning superfast at 30 Mbps is a meaningful step up from the USO minimum but not a premium standard by 2026 benchmarks.

Superfast vs Ultrafast vs Gigabit

Ofcom uses three tiers: superfast (30 Mbps+), ultrafast (100 Mbps+), and gigabit (1,000 Mbps+). Ultrafast coverage reached approximately 78% of UK premises in 2026, broadly aligned with FTTP coverage. Gigabit coverage reached 87% as network upgrades accelerated. The industry uses these terms inconsistently — some providers market FTTC as superfast and any FTTP as ultrafast, while others call all FTTP packages 'gigabit capable' whether or not the specific plan offers 1 Gbps. The most reliable reference is the actual speed (in Mbps) rather than any marketing category.

With FTTP prices starting from £26/month — comparable to FTTC — there is little reason to choose a superfast package when Full Fibre is available at your address. Enter your postcode to compare all broadband options and speeds available at your property.

Frequently Asked Questions

What counts as superfast broadband according to Ofcom?

Ofcom defines superfast as a download speed of 30 Mbps or above. Any connection delivering at least 30 Mbps qualifies — whether that is FTTC, FTTP, cable, or 5G home broadband.

Is superfast broadband fast enough for gaming?

For online gaming, speed matters less than latency. A 30 Mbps connection with 20 ms latency is better for gaming than a 100 Mbps connection with 50 ms latency. FTTP offers both fast speeds and low latency (5–12 ms), making it preferable. FTTC at 36–67 Mbps is adequate for gaming if latency is under 30 ms.

What percentage of UK homes have superfast broadband?

As of early 2026, Ofcom data shows superfast broadband (30 Mbps+) is available to approximately 97% of UK premises. The remaining 3% are predominantly in rural or remote locations not yet served by FTTC or FTTP.
