Sky’s broadband range now stretches from entry-level fibre on copper lines to multi-gigabit full fibre plans. Average download speeds start at 36Mb on Superfast 35 and rise to 5000Mb on Full Fibre 5 Gigafast+.
Sky Full Fibre Gigafast+ is the provider’s fastest plan. It runs on CityFibre’s XGS-PON network and delivers average download and upload speeds of 5Gb per second at peak times. The package includes Sky’s first Wi-Fi 7 hub.
Upload speeds on Sky’s Openreach FTTP plans remain asymmetrical. Full Fibre 500 offers 73Mb uploads, while Full Fibre Gigafast (~900Mb) comes with 100Mb uploads. By contrast, the 2.5Gb and 5Gb tiers on CityFibre are symmetrical, giving the same upload and download speed.
Sky broadband is available nationwide on the Openreach network, with full fibre reaching over 15 million premises. Multi-gigabit options are limited to CityFibre areas, currently covering 3.5 million premises.
Sky broadband can be taken on its own or bundled with Sky Stream and Sky Glass. Customers also receive options like WiFi Max, a whole-home Wi-Fi guarantee, and switching credits worth up to £200.

Sky’s broadband range in 2025 covers everything from basic entry speeds to multi-gigabit full fibre. All plans come with unlimited usage and are sold on 24-month contracts. Annual prices apply each April.
- Superfast 35 averages 36Mb down and 9Mb up. It is the cheapest tier and suits small flats or one-to-two person households where usage is light. HD streaming and browsing run without issue, but downloads take longer.
- Superfast offers 67Mb down and 18Mb up. This is the highest speed still delivered over copper. It can support a couple of UHD streams or several devices online at the same time, but is slower than full fibre.
- Full Fibre 75 delivers 75Mb down and 18Mb up. This is the first step on Sky’s full fibre ladder and offers steadier performance than copper-based plans.
- Full Fibre 100 raises speeds to 100Mb down and 20Mb up. It suits families streaming and video calling on multiple devices.
- Full Fibre 150 gives 150Mb down and 27Mb up. This tier works well for households with game downloads, large updates and several active TVs.
- Full Fibre 300 offers 300Mb down and 49Mb up. It provides headroom for bigger families, frequent UHD streaming and cloud backups.
- Full Fibre 500 delivers 500Mb down and 73Mb up. It shortens big downloads to minutes and comfortably handles many simultaneous users.
- Full Fibre Gigafast reaches around 900Mb down and 100Mb up. It is the fastest Openrach-based plan, giving enough capacity for large households with heavy streaming, gaming and downloads.
There are two new tiers that run on CityFibre’s XGS-PON platform.
- Full Fibre 2.5 Gigafast+ averages 2500Mb down and 2500Mb up.
- Full Fibre 5 Gigafast+ doubles this again to 5000Mb down and 5000Mb up.
They deliver symmetrical speeds and come with Sky’s Wi-Fi 7 hub. They are designed for homes with cutting-edge hardware, or where many devices are active at the same time.
Sky’s 5Gb plan is now the fastest package offered by a major UK provider, sitting above BT’s 900Mb and Virgin Media’s 2Gb tiers.
Part Fibre vs Full Fibre
Sky broadband comes in two different forms depending on your postcode:
- FTTC (Fibre to the Cabinet), also known as “Superfast”, where fibre runs to the street cabinet and copper phone wiring delivers the last stretch.
- FTTP (Fibre to the Premises), marketed as “Full Fibre”, where fibre-optic cable runs directly into your home with no copper bottleneck.
FTTC
Sky still offers FTTC packages for homes not yet covered by full fibre. These are branded as Superfast 35 and Superfast, with average download speeds of 36Mb and 67Mb respectively. They remain serviceable for light to moderate use but are limited by the copper element, which increases latency and reduces evening consistency. For a single person or small household, these speeds can still handle HD streaming, browsing and video calls, but capacity is stretched in busy households.
FTTP
The focus in 2025 is firmly on FTTP. Sky’s Full Fibre plans start at 75Mb and scale all the way up to 5Gb symmetrical in areas served by CityFibre’s upgraded network. FTTP eliminates the variability associated with copper, offering lower latency, higher throughput, and stable evening performance. For many customers, upgrading from FTTC to FTTP is the biggest improvement they will notice in home connectivity.
Speeds and Performance
Sky quotes “average” speeds based on Ofcom’s requirement that at least 50% of customers must achieve those speeds during the evening peak of 8–10pm. This ensures advertised speeds reflect actual speed during the busiest hours.
When you sign up, Sky also provides a personalised Minimum Guaranteed Speed (MGS). This figure is based on your line conditions and is shown at checkout. If your line consistently underperforms below that figure for three consecutive days, and Sky cannot resolve it within 30 days, you are free to exit the contract without penalty.
Mid-range performance
For most households, Full Fibre 150 and 300 offer the best balance of speed and price. They can comfortably support several UHD streams, large downloads and regular cloud backups at the same time.
Higher tiers
Full Fibre 500 and Gigafast (900Mb) add significant headroom. For large households with heavy users, these speeds mean 100GB game updates finish in minutes rather than hours, and simultaneous high-bandwidth tasks do not interfere with each other.
Multi-gigabit tiers
2.5Gb and 5Gb Gigafast+ are ideal for power users. They are delivered on CityFibre’s XGS-PON fibre, paired with Sky’s new Wi-Fi 7 hub. To take full advantage, devices must support Wi-Fi 7 or have 2.5GbE wired ports. Most existing laptops and consoles remain limited to 1Gb, meaning the extra bandwidth is only fully utilised when multiple devices are active at once.
Latency and jitter
Latency is a critical measure for gaming and real-time work. On Sky FTTP, wired round-trip times are typically single-digit to low-teens milliseconds, with very low jitter. By comparison, FTTC lines often see higher evening latency and occasional packet loss due to copper congestion. This is one of the main reasons households upgrading from FTTC to FTTP notice such a dramatic improvement in responsiveness.
Routers and WiFi Max
Sky offers different routers depending on the tier:
- Sky Broadband Hub – Supplied with FTTC and entry-level fibre plans.
- WiFi Max Hub (Wi-Fi 6) – Standard on mid-range FTTP packages. Supports mesh networking.
- Wi-Fi 7 Hub – Exclusive to Gigafast+ plans. Offers the latest Wi-Fi 7 standard with multi-gigabit wireless capacity.
WiFi Max Add-on
WiFi Max is available as an add-on across the range. It includes:
- Mesh pods to extend coverage
- An in-home Wi-Fi guarantee with a minimum speed threshold in each room (varies by package)
- App-based management, including parental controls, device prioritisation and advanced security
- Mobile data backup for use during broadband outages
Pods should be positioned midway between the hub and the weak-signal area, not at the edge of coverage, to be most effective.

Installation and Switching
Moving to Sky broadband is straightforward. Orders are coordinated with Openreach or CityFibre depending on your network.
- FTTP installs typically require an engineer visit to fit an ONT (Optical Network Terminal) inside the property.
- FTTC installs can usually be activated remotely on an existing phone line.
Sky also offers a switching credit scheme, reimbursing early termination charges from your old provider up to a fixed limit. Customers must submit their final bill, and approved claims are credited to the Sky account within weeks. This makes Sky a safer option for households who are still in contract but want to move to full fibre.
Bundling with Sky TV
Broadband can be taken on its own or bundled with Sky’s TV platforms.
Sky Stream
Sky Stream is a dish-free service delivered entirely over broadband. Packages include:
- Essential TV – From £15 per month on a 24-month plan or 31-day rolling contract. Includes Sky Atlantic, Netflix with ads and discovery+.
- Ultimate TV – From £22 per month. Adds Sky Max, Sky Comedy, Sky Crime, Sky Documentaries and more, alongside Netflix and discovery+.
Add-ons are available for Sky Sports, Sky Cinema, Kids, UHD and Dolby Atmos. Customers can also add extra pucks for multi-room use.
Sky Glass and Glass Air
Sky Glass is Sky’s all-in-one option that merges broadband, TV and streaming into a single product. It comes as a 4K Ultra HD television with Dolby Atmos sound built in, removing the need for a separate set-top box. Customers stream channels and on-demand content directly over their Sky broadband connection, with no satellite dish or external receiver required. Sky Glass is sold in three screen sizes—43-inch, 55-inch and 65-inch—and can be bought outright or taken on a monthly repayment plan alongside broadband.
Sky Glass Air is the lower-cost version launched in 2024. It delivers the same interface and content line-up but without the bundled television hardware. Instead, it connects to an existing TV through a small streaming device. This makes it a cheaper way to access Sky’s channel packs while still using broadband as the delivery method.
Both Glass and Glass Air integrate seamlessly with Sky’s broadband packages and support the full range of add-ons. Customers can add Sky Sports, Sky Cinema, UHD/Atmos upgrades and children’s content. Netflix comes bundled with Ultimate TV, and whole-home add-ons allow extra rooms to be equipped with additional pucks or devices.
Because everything is streamed over the broadband connection, performance depends on line speed and Wi-Fi setup. Sky recommend a minimum of 25Mb for a single UHD stream, with faster tiers such as Full Fibre 150 or above giving more headroom for multiple rooms watching simultaneously. When paired with WiFi Max pods, the system is designed to deliver consistent coverage across larger homes, reducing buffering or dropouts during peak evening hours.
Customer service and reliability
Sky usually performs well on customer complaints. In Ofcom’s Comparing Customer Service 2025 report, covering the full year of 2024, Sky recorded just 21 complaints per 100,000 broadband customers. This was the lowest rate of all major providers, making Sky the least-complained-about brand in the fixed broadband market.
Call centre performance also improved across the industry in 2024. Ofcom reported an average wait time of 2 minutes 1 second, down from 2 minutes 37 seconds in 2023. Vodafone answered calls the fastest, averaging 25 seconds, while KCOM had the longest waits at over 7 minutes. Sky’s results placed it among the providers at or better than the industry average, with low abandonment rates when customers needed to get through.
Reliability is another area where Sky’s service stands out. Ofcom’s latest connectivity tracking shows that full-fibre is being rolled out rapidly, with gigabit-capable networks now passing most UK homes. Customers moving from part-fibre to full-fibre connections benefit from more consistent evening speeds, lower variation in throughput, and fewer slowdowns at busy times.
Although Ofcom’s dedicated Home Broadband Performance programme finished in 2023, its final results confirmed that full-fibre delivers steadier peak-time performance than copper-based fibre. The absence of last-mile copper bottlenecks reduces congestion and keeps latency low. Those findings continue to hold as more customers migrate from FTTC to FTTP.
What this means for Sky customers
- Complaint handling – Sky generates fewer formal complaints to Ofcom than rivals, which points to smoother day-to-day service and better handling of issues when they arise.
- Contact centre – Average call waiting times are improving across the industry. Sky remains in the group of providers where customers can get through more quickly and with fewer dropped calls.
- Evening performance – On full-fibre, households should see stable peak-time speeds and lower latency compared with older FTTC lines. This means fewer interruptions to UHD streaming, video calls or online gaming.
For anyone upgrading from FTTC to Sky’s full-fibre tiers, the benefits are clear: fewer slowdowns in the 8–10pm busy period, more reliable video calls, and more stable speeds on every connected device. On Sky’s new multi-gigabit plans over CityFibre, these improvements go further, but single-device performance still depends on whether your equipment supports 2.5Gb Ethernet or Wi-Fi 7.
