What is Sky Broadband Boost?

Last verified: 28 September 2026

Sky Broadband Boost is designed to help with the WiFi experience rather than the broadband speed itself.

It is an optional add-on that combines WiFi support with a number of extra services, including help with coverage, engineer appointments and monitoring of your broadband connection. This could be useful if you regularly deal with weak WiFi, connection problems or simply want more support when something goes wrong. However, Boost is not a universal upgrade for Sky customers. It is only available with certain Sky packages and customers, and Sky also offers Sky WiFi Max as an alternative in some cases.

If you are considering Sky Broadband Boost, it is worth knowing what it includes, who can get it and whether you actually need it.

What does Sky Broadband Boost currently include?

According to Sky's own guidance, Sky Broadband Boost currently includes several features designed to improve your WiFi experience:

WiFi in every room, or your money back: 

Sky's WiFi Guarantee promises a minimum download speed of 3Mb/s in every room. If an engineer visit confirms that you are not getting this, Sky can credit one month of broadband and one month of Boost. You can also cancel Boost without an early termination charge. This credit does not cover Sky Talk, call charges, or other add-ons such as McAfee, and only one claim can be made per address. The guarantee can be claimed once during your 24-month minimum term. However, this guarantee only applies if you have taken Sky Broadband Boost after 4 September 2019.

If your router provides a good connection in one room but WiFi becomes unreliable further away, Boost can be useful. The service includes WiFi boosters on loan, which can help extend the coverage of your existing Sky setup.

This could be particularly useful in larger homes, multi-storey properties or homes with thick walls, where the router alone may struggle to provide consistent coverage.

Engineer visits at a time that suits you: 

Boost removes the usual additional charge for evening and weekend WiFi engineer visits. Boost can be useful if you need an engineer to investigate a WiFi problem but cannot easily be available during normal weekday hours.

This gives you more flexibility when arranging support, particularly if you work full-time or have other daytime commitments. It can also be useful if the problem is affecting specific areas of your home and needs an engineer to assess the WiFi setup rather than simply troubleshooting the connection remotely.

Daily line checks:  

Sky checks your broadband line once a day to look for potential problems. This means Sky may be able to identify certain issues with your connection before you notice that something is wrong or have to contact customer support yourself.

The checks are designed to monitor the condition of your line rather than increase your broadband speed, so they should not be viewed as a performance upgrade. One thing to be aware of is that the daily check can cause a brief interruption of up to 90 seconds while it takes place. For most households this should be relatively minor, but it is worth knowing about if you rely on your connection continuously.

Mobile data during outages: 

If you are a Sky Mobile customer, Boost can provide some backup connectivity when your Sky broadband goes down. For a qualifying outage lasting 30 minutes or more, you can receive 2GB of mobile data, which is credited to your Sky Mobile Piggybank.

This could be particularly useful if you work from home, need to stay connected while travelling around the house, or simply want a way to get online while waiting for your broadband to come back. There are limits to the benefit: you can receive a maximum of three credits per month and 24 credits during any 24-month period. The mobile data benefit is also only available to Sky Mobile customers, so it should not be treated as a general backup connection for all Boost subscribers.

Sky Broadband Boost comes with its own 24-month minimum term that runs alongside your broadband contract. Prices for broadband add-ons can change, so check the current price with Sky before signing up.

Who can get Sky Broadband Boost?

According to Sky, Boost is available as an optional add-on for new Ultrafast customers, and as a re-contract for existing Boost customers. It is not available to everyone. If Boost is not available with your account, Sky may offer Sky WiFi Max instead. If you still use Sky Q, check compatibility with Sky before signing up.

Sky Broadband Boost vs Sky WiFi Max

If you are looking for better WiFi coverage, you may be offered either Sky Broadband Boost or Sky WiFi Max. Sky says WiFi Max may be a better fit if Boost is not available to you. Features and pricing may differ, so check Sky's WiFi Max page and compare both before choosing.

The 3Mb/s Boost guarantee is relatively modest. It may be enough for basic browsing, messaging and some streaming, but households with several devices or higher-speed activities may need more.

If WiFi Max is available to you, compare what both options offer before deciding which one is worth paying for.

Is Sky Broadband Boost worth it?

It depends on what you need from your home WiFi.

Boost may suit you if:

• You have poor WiFi coverage in parts of your home and Boost is available with your package.
• You want the option of evening or weekend engineer visits without an additional charge.
• You like the reassurance of daily checks on your broadband line.
• You want backup mobile data if your broadband connection goes down.

It may not be the best option if:

• Sky WiFi Max is available to you and, after comparing the two on Sky's website, looks like a better fit.

• Your household needs consistently higher speeds than the 3Mb/s guarantee provides.

How to add or cancel Sky Broadband Boost

If Boost is available with your Sky package, you can check your options through Sky or contact Sky directly. Before adding it, check the terms carefully because Boost has its own 24-month minimum term.

If you are cancelling Boost but keeping Sky broadband, you do not need to cancel your broadband service. If you are leaving Sky broadband altogether, the cancellation process is different.

Boost also includes WiFi boosters on loan at no extra cost. These need to be returned if you cancel your Boost subscription.

See our guide to cancel Sky broadband for more information.

Sky Broadband Boost is one factor to weigh up alongside your overall broadband package, not a reason on its own to switch or stay. If you are comparing your options more broadly, it is worth checking availability at your address.

Frequently asked questions

Is Sky Broadband Boost available to everyone?

No. Sky Broadband Boost is not available to every customer. It is available to new Ultrafast customers, or existing Boost customers re-contracting. Sky may offer WiFi Max instead if Boost is not available with your account.

What is the difference between Sky Broadband Boost and Sky WiFi Max?

Both are Sky WiFi add-ons. Boost is not available to everyone, and Sky says WiFi Max may be a better fit if Boost is not available to you. Check Sky's WiFi Max page for its current features and price so you can compare the two.

Does Sky Broadband Boost make my broadband faster?

Boost does not increase the underlying speed of your broadband connection. It is designed to improve WiFi coverage around your home and provides additional features such as engineer support and daily line checks.

Can I cancel Sky Broadband Boost separately from my broadband?

Yes. Boost is a separate add-on, so you can cancel it without cancelling your Sky broadband. However, it has its own 24-month minimum term, so check the terms that apply to your account before cancelling.

Do I need to return the WiFi boosters if I cancel Boost?

Yes. The boosters provided with Boost are loaned to you and need to be returned when you cancel the subscription.
