Broadband speeds explained

When we talk about broadband speeds, there are actually two different types:

Access line speed: This is the maximum speed between your local telephone exchange and your router, so it’s the connection you receive into your home.

Throughput speed: This is the actual speed you experience on a device that’s connected to your broadband, so it’s the connection from your router to your device.

To better understand what these speeds mean, watch this video:

  • What are my broadband speeds?

    Access line speed: To find this out, visit My Broadband and sign in using your Sky iD. You can also check it in the My Sky app, by selecting Manage account > Broadband & Talk > Broadband speed. If you’re new to the app, visit our My Sky app page to find out more.

    Throughput speed: There are several free websites that will measure this. Enter “Broadband speed test” into a search engine on the device you’d like to test and follow the instructions on your selected site.

  • What if I’m not receiving the speed I was expecting?

    Please sign into My Broadband so we can run some tests on your connection, or follow our broadband diagnostic

  • What can affect my broadband speeds?

    Access line speed: The speed and quality of this depends on how far you live from the exchange, unless you’re a Sky Fibre customer.

    Throughput speed: This will naturally be lower than your access line speed as it’s affected by factors such as the layout of your home or any interference between your router and your devices.

    Both speeds will also depend on which Sky Broadband product you have. Read the below PDF for more information:

  • Glossary of speed terms

    Access Line Download Speed

    This is the speed at which data is transferred from the internet to you. Faster download speeds means faster downloads of music tracks and photos, and better quality of streamed online videos. 

    Access Line Upload Speed

    This is the speed at which data is transferred from you to the internet. Faster upload speeds improve your overall internet experience, as your actions (clicking on links on a web page, sending emails, uploading photos) are communicated to the internet quicker.

    Estimated Access Line Speed

    When you're ordering Sky Broadband, we'll give you an estimate of the fastest download speed that your phone line can support. This is based on the length and quality of your phone line.

    Maximum product headline speeds

    This is the advertised fastest download and upload speeds, for your Sky Broadband product, which can be achieved between a Sky Hub and the phone exchange in ideal circumstances. The speed you actually experience can be anything up to this speed, and is affected by the line length from the exchange and quality of your phone line.

    Sky Broadband Connect customers only

    Sky Broadband Connect is subject to a Network Management Policy. This means that available network bandwidth is shared equally by all Sky Broadband Connect customers who are online at the same time, so broadband speeds may be slower at peak times (from 5pm to 12am weekdays and all day at weekends). The Network Management Policy applies only to Sky Broadband Connect customers - see more details in the Sky Broadband Terms and Conditions.

Sky subscribes to Ofcom's Voluntary Code of Practice on broadband speeds.
