Sky offers Ultrafast Broadband from £35 per month with average download speeds of 145Mbps.

In the UK, Sky has launched their next-generation home broadband service, Sky Ultrafast Broadband. It offers average download speeds of 145Mbps: more than 12 times faster than their Essential Broadband service (11Mbps) and more than twice as fast as Superfast Broadband (59Mbps).

Sky’s Ultrafast Broadband service is currently available for £35 per month on an 18-month plan.  It uses either or full fibre (fibre to the home) technology, depending on what is available at your address.

We’ll start by looking at the Ultrafast broadband plans, before looking at the Sky Ultrafast Broadband router and the speeds available on the service. Finally, we’ll look at the availability of the service before comparing it to alternatives from other providers like BT, TalkTalk and Virgin Media.

Sky Ultrafast Broadband Plans

Sky Ultrafast Plans

In the UK, Sky currently offers just a single Ultrafast Broadband plan, with average download speeds of 145Mbps. This is currently available for £35 per month:

See Sky Ultrafast Broadband Deals →

At the end of your 18 month contract, the price will increase to Sky’s standard monthly prices (currently £44/month for Ultrafast Broadband).

This is the only ultrafast home broadband service currently available from Sky. In mid-2019, Sky originally announced two Ultrafast broadband plans (Ultrafast 1 with average download speeds of 145Mbps and Ultrafast 2 with average download speeds of 285Mbps). Unfortunately, the Ultrafast 2 plan hasn’t been mentioned for more than a year so it’s likely the launch of this is on hold for the time being.

Another important thing to note about Sky’s Ultrafast Broadband is that the Sky Talk phone service is delivered using voice over IP (VoIP) technology. This means the internet connection is used to deliver your home phone service. Your landline telephone will therefore need to be plugged in to your Sky Hub router for it to work. One downside of this is that if the power fails to your Sky Hub router, you’ll lose your home phone service. For this reason, Sky says their Ultrafast Broadband service isn’t suitable for people who rely on their landline for emergency calls.

Superfast vs Ultrafast Broadband

Sky’s Ultrafast Broadband offers download speeds that are twice as fast as their Superfast Broadband.

The following table shows a side-by-side comparison of Superfast Broadband and Ultrafast Broadband:

Superfast Broadband Ultrafast Broadband
Monthly Price: £28 per month £35 per month
Contract Length: 18 month contract 18 month contract
Download Speed: 59Mbps average download 145Mbps average download
Upload Speed: 18Mbps average upload 27Mbps average upload
Technology: FTTC (or FTTP – see note†) or Full Fibre (FTTP)
Router: Sky Hub (Sky SR203) Sky Hub (Sky SR203)
Availability: Over 90% of UK homes Approx 20% of UK homes

† If you’re living at an address that’s connected to the Openreach full fibre (FTTP) network, you’ll still be able to get Superfast Broadband from Sky. However, this will be delivered to you over the full fibre connection, rather than fibre-to-the-cabinet (FTTC) as it is for most other customers.

Sky Broadband Boost

You can add Sky Broadband Boost to your Ultrafast Broadband service for an extra £5/month. This gives you five additional features:

  • Guaranteed wi-fi in every room of your home: Guaranteed speeds of at least 3Mbps in every room of your home, or money back on your Sky Broadband Boost subscription. You’ll be sent a Sky Wi-Fi Booster to help with the Wi-Fi coverage if required.
  • Daily line checks: An automated check on your phone line each day to ensure your Ultrafast Broadband service is working correctly.
  • Parental controls app: Access to the Sky Broadband Buddy parental controls app. This is designed to work both on wi-fi and on a mobile data connection.
  • Flexible engineer visits: You’ll get free evening and weekend appointments with the Sky Broadband Tech Team (normally £15 for customers without the Broadband Boost).
  • 2GB mobile data for unplanned outages: An extra 2GB of data will be added to your Sky Mobile Piggybank if there’s an unplanned outage on your broadband service.

Sky Ultrafast Broadband Router

The Sky Broadband Hub router supports dual-band Wi-Fi 5 technology, with 8 built-in antenna to optimise performance and coverage through your home. It supports up to 64 devices on Wi-Fi at the same time. There are also 4 Gigabit Ethernet ports available for connecting wired devices to your home network.

Sky Ultrafast Speeds

The average download speed on Sky’s Ultrafast Broadband service is 145Mbps, with a maximum download speed of up to 150Mbps (dependent on your line).

You’ll need to carry out your speed test at The guarantee doesn’t consider the impact of poor Wi-Fi in your home (there’s a separate 3Mbps Wi-Fi Guarantee in Sky Broadband Boost if you’d like this as well).

The average upload speed on Sky’s Ultrafast Broadband is 27Mbps.

Coverage & Availability

Sky’s Ultrafast Broadband service is available in about 20% of UK homes. This includes 3 million homes that are able to get a full fibre broadband connection from Openreach and another 2.8 million homes that are able to get a broadband service.

In the past, Ultrafast Broadband was only available in areas. However, in November 2020, Sky extended it across the rest of the country to work in homes that have a full fibre connection from Openreach. The ambition is for full fibre technology to be available in 20 million homes within the next five to ten years.

  • I upgraded to sky’s Ultrafast (gfast) on the first of December. I had about 70mbps down before but now I’m getting a full 150.
    I work from home (as most of us are) and I have to say the difference is amazing. I am really pleased. I remote into my work desktop from home and I use a lot of maps and images that take a lot of speed to load and the delay now is almost impossible to detect (obviously this didn’t exist when I was using my own laptop on Google maps but as I remote in, it needs a lot of speed)

    I connect via ethernet and sit right next to the router anyway so speed is always A*.
    I think in this time I’ve gone below 100 Mbps once.

    Super happy with Gfast & sky.

  • Open reach engineer spent most of the morning connecting and fitting. Did a neat job discreetly routing cable round to new hole he drilled in wall. Fitting probably depends on your luck with the engineer. Super fast broadband doesn’t mean anything if servers can’t respond well. We had 37mpbs. Main benefit is upload speed, now 28 mbps, but that can be hugely improved from 6 to 18 mbps at the intermediate tier.

  • Just to update you despite having superfast, they need to run a new line from the telegraph pole down the front of the house then they fit a new open reach phone socket inside and join the two outside .
    My house had just been re rendered which means a black cable down the white render disappointing
    Second issue to consider, do you want cables tacked around the door frames to the router?
    I’m putting mine under the floors, thank fully I got some new fiber cable of a bt engineer so the Inside will be tidy they just need to join it outside.
    It’s a real shame the dont offer a pre inspection official visit and leave cable for thoese of us who want a tidy house. Hope it’s worth it

  • I have purchased it and it’s being fitted in March, does an engineer need to come our before hand to check any thing? I can get an answer, not sure if I need a new BT phone socket, I want my wires under the floor not tacked around door frames , so I need to know what they will he doing.

    • mark price replied:

      Openreach came to our front door today and did some work on the outside of the house in prep for the engineer coming on March 15th
