What does Sky Gigafast offer?

Sky Gigafast Broadband is the provider's fastest broadband plan, offering average download speeds of 900Mbps, paired with average upload speeds of 90Mbps at peak times.

The latest pricing for new customers is:

Sky include a digital home phone line as standard with their broadband deals, and customers can choose to add optional call plans, as we cover below.

Since relaunching their full fibre broadband line in September 2024, this Full Fibre Gigafast plan now comes with their latest router, the Sky Max Hub, included at no extra cost. Customers can also add a WiFi guarantee with up to three Plume WiFi Pods for an extra £3 per month to help boost signal around larger homes.

Gigafast comes with a 24-month minimum term, which is fairly standard, and matches other 24-month plans from providers such as BT and Vodafone.

This has pros and cons for customers, while some may prefer the flexibility of being able to leave or switch sooner, introductory prices will remain lower for the duration of the minimum term - so customers can save money for longer.

Sky doesn't have set annual price rises, but they do increase prices, usually by a rate of inflation or less, as prices went up 6.7% on average for 2024.

Gigafast Broadband was first launched in April 2022, and subsequently removed from sale in November 2022 as Sky wanted to make improvements to their network to support the package's fast speeds. However, since March 2023, it's been available for new customers again.

Gigafast and calls

Unlike many full fibre broadband providers, including TalkTalk, Plusnet, and BT themselves, Sky include a home phone line as standard with pay as you go calls.

Calls on this plan cost 27p per minute, plus a 25p connection charge.

Customers can also choose to add one of the following inclusive call plans if they regularly use their home phone:

All Sky Talk plans are provided on 24-month minimum terms that run alongside the broadband deal, and may also be subject to price increases during the minimum term.

Sky Gigafast and Sky TV

One of the major draws of Sky broadband is the ability to bundle Sky TV with extra discounts.

Sky Gigafast Broadband can be taken with Sky Stream or Sky Glass for savings of around £9 per month compared to taking the services separately.

Right now, Sky Stream with Sky Gigafast Broadband is only £54 per month for 24 months, which is good value considering Gigafast is £43 per month on its own and Sky Stream is £20, saving customers £9 per month over taking the services separately.

Setup is also currently free with Sky TV and broadband bundles.

Sky TV can be customised with premium TV packs from Sky Sports, Sky Cinema, TNT Sports, Sky Kids, Disney+, and comes with Sky Entertainment and Netflix in HD as standard.

How does Sky Gigafast compare?

Most major broadband providers now offer gigabit-capable broadband packages, and for those who want such fast speeds, the pricing is reasonably competitive.

Sky Gigafast Broadband is currently priced around the middle of the market, coming in cheaper than deals from BT and TalkTalk.

However, as we've seen above, Sky Gigafast is arguably even better value when bundled with Sky TV, as it then effectively costs just £35 per month.

Sky also have market-leading customer service, and that's something to bear in mind when comparing packages from some more budget providers who tend to gather more complaints.

Here's how Sky Gigafast looks against its closest rivals:

Sky Gigafast is currently more expensive than equivalent packages from Vodafone, Plusnet and Virgin Media, but is quite a bit cheaper than equivalent deals from TalkTalk, BT and Zen Internet.

It is worth considering other factors when comparing broadband providers however, such as customer service, the broadband router, and extras like whether a home phone line is provided (if needed), and optional TV plans.

How fast is Sky Full Fibre Gigafast?

Sky Full Fibre Gigafast Broadband offers average download speeds of 900Mbps, that means at least 50% of Sky's customers receive this speed during the peak hours of 8pm to 10pm when the network is at its busiest.

Sky Gigafast also offers average upload speeds of 90Mbps.

The Sky Gigafast broadband connection is full fibre to the home, this results in a faster and more reliable Internet experience. Because fibre is laid directly into a customer's home distance from the nearest exchange or street cabinet no longer cause an issue or any speed degradation as was the case with older fibre to the cabinet technologies.

Full fibre is the most reliable broadband connection available in the UK. While delivery conditions can vary between individual homes, the underlying technology offers a more robust and faster experience, with lower latency and less likelihood of disconnections and faults.

Minimum speed guarantee

Sky are signatories of Ofcom's code of practice on broadband speeds, this means they provide both personalised estimates at the point of sign up, and minimum speed guarantees.

For example, when we looked at our postcode, we were given speed estimates of:

Personalised estimates aim to give customers the best indication of the broadband speed their individual property can expect to receive by signing up to the Sky Gigafast plan.

Minimum speed guarantees on the other hand provide an absolute minimum speed that if a customer goes on to experience speeds slower than this, they have the right to exit their contract early and without penalty.

Sky also go a step further than this with their Sky Speed Guarantee which applies to this Gigafast plan. Customers who receive speeds less than their minimum guaranteed speed can claim one month's broadband subscription back.

WiFi speed guarantee

Sky Gigafast customers get the Wall-to-Wall guarantee for free, this promises minimum download speeds of 3Mbps in every room. If customers don't get this minimum speed over their wireless network, they can claim one month's broadband subscription back.

However, Sky have also recently launched an updated WiFi guarantee in the WiFi Max add-on. For an extra £3 per month Sky Gigafast customers can an upgraded WiFi guarantee that promises minimum speeds of 25Mbps in every room.

Sky also bundle daily line checks and free off-peak engineer visits, along with a 2GB data boost for Sky Mobile plans if the fixed-line broadband goes down.

If the WiFi guarantee fails to deliver, Sky will send out up to 3 WiFi boosters, and eventually an engineer, and if that still doesn't achieve those minimum speeds, customers will get one month's broadband subscription refunded.

Sky Max Hub

Sky Gigafast now comes shipped with the Sky Max Hub, this is a dual-band WiFi 6 router that can support up to 250 devices wirelessly and has four ethernet LAN ports for wired connections.

The Sky Max Hub is able to provide faster speeds to any WiFi 6 enabled devices, including Sky Stream and Sky Glass, so it's a welcome addition as a standard device for the Sky Gigafast broadband plan.

Sky's WiFi Max add-on costs £3 per month on a 24-month minimum term and bundles Sky's WiFi guarantee along with more advanced router security, and the option to pause devices and set schedules through the MySky app.

Overall, we'd say anyone looking at a 900Mb broadband package should seriously consider the WiFi Max add-on for the upgraded wireless speed promise of 25Mbps and additional router-level controls.
