Sky Business Broadband Review 2026: Prices, Speeds & Alternatives Quick Answer
Sky Business Broadband is a strong option to compare for UK SMEs that want broadband, digital phone features and business continuity tools from one established provider.
Depending on the package and availability at your address, Sky Business can provide full-fibre broadband, digital voice lines, network-level security and automatic 4G backup.
We think Sky becomes considerably more interesting when your business values the extras rather than simply looking for the lowest broadband price.
For a shop, salon, café, clinic or small office, backup connectivity and integrated voice services can be genuinely useful.
For a business that simply wants the cheapest fibre connection, however, Sky may be less compelling.
And if connectivity is absolutely critical to your operation, we would compare Sky with a business leased line rather than relying on standard business broadband alone.
Broadband availability and speeds are postcode-specific, so always compare what is actually available at your premises.

Key Takeaways
Sky Business Broadband is aimed primarily at SMEs wanting broadband plus useful business features. Full-fibre availability and actual speeds depend on your address.
Sky Business offers different package levels rather than one standard broadband product.
Full-fibre Pro and higher-tier packages can include automatic 4G backup through Connection Pro.
Sky states that the speed of its 4G backup connection isn’t guaranteed.
Business packages can include digital voice lines and unlimited UK landline and mobile calls, subject to package terms and acceptable-use conditions.
Network-level protection against phishing and malware-infected sites is included on relevant packages.
Speed Flex can increase available speeds on eligible full-fibre packages.
Sky Business accounts provide information including download and upload speeds and the Guaranteed Minimum Download Speed for the service.
Static IP and other services can be available as add-ons.
We think Sky is strongest for small businesses that will actually use its backup, voice and security features. Businesses prioritising dedicated bandwidth, symmetrical speeds or stronger service guarantees should compare leased lines.

What Is Sky Business Broadband? Sky Business Broadband provides internet connectivity and related services for UK businesses and so depending on the package and technology available at your premises, Sky Business services can combine:
Business broadband
Full-fibre FTTP
Digital voice services
Automatic 4G backup
Network-level security
Static IP options
Additional voice lines
Speed upgrades on eligible packages
This makes it different from a bare-bones broadband service that simply gives your business an internet connection.
Our take
We think this is the main reason to consider Sky Business.
If you only need internet access for one laptop and a few emails, there may be cheaper ways to get online.
But if your broadband supports:
Card machines
Cloud software
VoIP calls
Online bookings
Customer Wi-Fi
EPOS
Video calls
then backup and business-specific features start to matter much more.
How Much Does Sky Business Broadband Cost? Sky Business Broadband pricing depends on:
Your postcode
Available broadband technology
Package
Broadband speed
Contract
Voice requirements
Speed Flex
Static IP
Additional services
We don’t recommend relying on old third-party Sky price tables.
Broadband promotions change and the deal available at one address may not match another.
Instead, compare the live quote available for your premises and when comparing Sky against another provider, calculate:
Total contract cost = monthly charge × minimum term + setup costs + required add-ons.
This gives you a much better comparison than looking at the headline monthly figure alone.
What we would check
Ask:
What is the monthly price?
How long is the minimum term?
Are there setup or activation charges?
Does the price change during the contract?
Is 4G backup included?
Is a static IP included?
Are voice services included?
Does achieving the speed you want require Speed Flex?
We think total contract cost is far more useful than comparing introductory monthly prices.
Compare Current Business Broadband Prices
How Fast Is Sky Business Broadband? Sky Business Broadband speeds depend on the technology and package available at your address and Sky’s business package documentation includes both part-fibre and full-fibre services.
Older FTTC services can provide download speeds of up to 76Mbps with upload speeds up to 19Mbps.
Eligible full-fibre packages can provide faster connections, with Speed Flex available on selected packages to increase the speed further.
Your actual quotation should provide estimates for your line.
Sky Business’s online account also provides speed information including:
Download speed
Upload speed
Guaranteed Minimum Download Speed
What we think
Don’t choose business broadband based solely on the largest advertised download number for many businesses, upload speed can be almost as important.
This is particularly true if your team regularly:
Uses Microsoft Teams
Uses Zoom
Uploads large files
Uses cloud backups
Hosts cloud-based applications
Uses multiple VoIP calls simultaneously
Always ask for both the estimated download and upload speed at your actual postcode.
Sky Business Full Fibre Broadband Sky Business offers full-fibre services where FTTP is available. FTTP means the fibre connection runs directly to the premises rather than relying on the older copper network for the final part of the connection which can provide:
Faster download speeds
Better upload performance
More capacity for multiple users
A more future-ready connection
Sky’s current business documentation includes full-fibre packages such as:
Advantage Full Fibre
Ultrafast Pro
and:
Ultrafast Max
with features varying by package.
Our view
If both FTTC and FTTP are available at your premises, we would normally start by comparing the full-fibre option.
Businesses are becoming increasingly dependent on:
Cloud applications
Video conferencing
Cloud telephony
Online payments
Remote working
Cloud storage
so buying a connection purely around today’s minimum requirements can be short-sighted.
What Is Sky Business Speed Flex? Speed Flex is available on eligible Sky Business full-fibre packages and it allows customers on qualifying packages to change the estimated download and upload speed of their connection.
Sky’s terms state that eligible customers can add Speed Flex and can later change or remove it subject to the relevant conditions and charges.
What we like
We think this is useful for businesses whose bandwidth requirements change.
For example, a growing company might initially choose a moderate connection and later need more bandwidth as it adds:
Employees
Cloud software
VoIP users
Video conferencing
Connected devices
Being able to change speed without necessarily replacing the entire broadband proposition adds useful flexibility.
However – check the cost of Speed Flex rather than assuming the faster speed is included in the headline package price.
Sky Business 4G Backup & Connection Pro Automatic 4G backup is one of the most commercially useful Sky Business features and Sky calls this Connection Pro.
It is included with eligible Pro and higher-tier packages.
If the main fixed broadband connection fails, connected devices can switch to the 4G backup connection.
Why we think this matters
For some businesses, losing broadband isn’t merely inconvenient and so it can mean losing:
Card payments
EPOS
Online bookings
Email
Cloud software
VoIP
Customer Wi-Fi
A café unable to process card transactions could lose revenue immediately.
A salon could lose access to its appointment system.
An office could lose cloud applications and calling.
So, for businesses like these, we think 4G backup can justify paying more than the cheapest broadband-only deal.
How Fast Is Sky Business 4G Backup? This is where we think businesses need to read the detail carefully – Sky states that devices using its 4G backup service can have a maximum download speed of 80Mbps.
But that is not a guaranteed speed.
Sky explicitly says it cannot provide a speed guarantee for the mobile backup connection.
Performance can be affected by:
4G signal strength
Building construction
Router position
Number of connected devices
Network congestion
Weather and atmospheric conditions
Sky advises customers buying eligible packages online to check 4G signal availability before ordering.
Our take
We think 4G backup should be treated as business continuity protection
rather than a second broadband line with identical performance.
It could keep card machines, emails and essential cloud services working.
We wouldn’t assume it will support an entire busy office exactly as the main full-fibre connection does.
Sky Business Digital Phone & Voice Services Sky Business packages can include digital voice services and depending on the package, this can include:
One or more voice lines
Calls to UK landlines
Calls to UK mobiles
Voice features
Additional voice lines for an extra charge
Current Sky Business package documentation provides one voice line on relevant Advantage and Pro services, while higher-tier packages can support additional lines.
What we think
Bundling voice with broadband makes sense for a small business with relatively simple telephone requirements.
For example:
Shop
Salon
Small office
Clinic
Restaurant
may only need a handful of phone lines.
A larger business with:
Call queues
Dozens of extensions
CRM integration
Call recording
Advanced analytics
Contact-centre functionality
should also compare a dedicated business VoIP system .
Sky Business Broadband Security Sky Business package documentation includes network-level security designed to help protect businesses against:
Phishing sites
Malware-infected websites
We like seeing basic security integrated into business broadband, but we wouldn’t treat it as a replacement for proper business cybersecurity.
Businesses should still consider appropriate:
Endpoint security
Multi-factor authentication
Backups
Email security
Access controls
Staff cybersecurity training
depending on their risks.
Does Sky Business Broadband Offer a Static IP? Sky Business account documentation identifies Static IP
as an available add-on.
A static IP can be useful for businesses using:
Remote access
VPNs
CCTV
Hosted services
Whitelisted business systems
Some VoIP configurations
If you require a static IP:
confirm whether it is included or chargeable on the specific Sky package you’re considering.
Read our Static IP Broadband guide .
Who Is Sky Business Broadband Best For? Small offices
We think Sky is a good fit where a small team wants broadband and voice services together.
Shops
Backup connectivity can be particularly useful where broadband supports card payments, EPOS and cloud software.
Salons & clinics
Sky can make sense where bookings, payments and customer communications all depend on internet connectivity.
Cafés & restaurants
We think the backup proposition becomes valuable where the connection supports payments, ordering or reservations.
Professional services firms
Full fibre can work well for businesses using cloud applications, video conferencing and digital phone services.
Home-based businesses
Sky Business can be worth comparing if you want business-specific features rather than a standard residential connection.
Who Should Compare Alternatives? Businesses primarily focused on price
If you simply want the lowest-cost connection, compare Sky carefully against lower-cost business broadband options.
Businesses needing symmetrical speeds
Standard broadband often has much faster downloads than uploads.
A leased line can provide symmetrical connectivity.
Businesses where downtime is extremely costly
4G backup is useful, but it isn’t equivalent to dedicated connectivity with a contractual service level.
Large offices
Businesses with many simultaneous users may need higher-capacity connectivity.
Multi-site businesses
Organisations operating several locations should also compare SD-WAN , managed WAN and multi-site connectivity.
Sky Business Broadband Pros & Cons Advantages
Established UK brand: familiar provider with dedicated business services.Full-fibre options: available where FTTP has reached the premises.4G backup: Connection Pro is included with eligible packages.Digital voice: useful for businesses wanting broadband and phone services together.Network-level security: protection against specified phishing and malware sites.Speed Flex: eligible full-fibre customers can alter their speed tier.Static IP option: useful for certain business applications.Guaranteed minimum download speed information: available within the business account and contract information.24/7 support: support is available for business broadband issues.
Potential Disadvantages
Not necessarily the cheapest: businesses focused solely on price should compare alternatives.Speeds are address-dependent: the best full-fibre services aren’t available everywhere.4G backup isn’t speed-guaranteed: actual performance depends on mobile conditions.Backup isn’t a leased line: businesses with critical uptime requirements may need dedicated connectivity.Add-ons can change the real cost: compare the complete package rather than headline broadband pricing.Longer commitments may apply: check the minimum contract term before ordering.Upload speeds matter: businesses shouldn’t compare download speed alone.
What We Like About Sky Business Broadband 1. The backup proposition is genuinely useful
This is the feature we think makes Sky most interesting for customer-facing SMEs and keeping card machines and essential cloud services running during a fixed-line outage can have a direct financial value.
2. Broadband and voice can sit together
For a small business, consolidating broadband and basic phone services can make administration easier.
3. Speed Flex provides room to grow
We like that eligible businesses can alter the speed of their full-fibre connection rather than necessarily changing the entire package.
4. Sky is transparent about 4G limitations
Sky explicitly states that it cannot guarantee mobile backup speeds.
We think that’s important information for businesses deciding how much they can rely on it.
5. The proposition is clearly designed for SMEs
Features such as voice, backup, security and static IP options make more sense for a business than a repackaged residential connection.
What We Think Could Be Better 1. Package pricing could be easier to compare
Business broadband pricing is inherently postcode-specific, but businesses benefit from being able to understand the likely total contract cost quickly.
2. 4G backup shouldn’t be confused with resilient dedicated connectivity
It’s useful protection.
It isn’t the same as having a secondary dedicated circuit or leased-line resilience.
3. Businesses need to pay attention to upload speed
Marketing naturally focuses on download speed.
We think cloud-heavy businesses should look much more closely at upload performance.
4. Some SMEs may be paying for features they don’t need
If you don’t need voice, backup or business extras, a simpler provider may represent better value.
Sky makes most sense when you will actually use the features you’re paying for.
Sky Business Broadband Alternatives BT Business Broadband
We think BT is one of the most obvious Sky comparisons if you want another major UK provider with broad business broadband availability and resilience options.
Virgin Media Business Broadband
Worth comparing where Virgin’s network is available and high download speeds are a priority.
Vodafone Business Broadband
We think Vodafone is particularly worth comparing if price or integration with business mobile services matters.
TalkTalk Business Broadband
Worth considering where straightforward business connectivity and pricing are priorities.
Zen Business Broadband
A useful alternative for businesses placing significant value on service and support.
Hyperoptic Business Broadband
Worth checking where its full-fibre network serves your building.
Business Leased Lines
We would move beyond ordinary broadband entirely if guaranteed bandwidth, symmetrical speeds and stronger uptime commitments are essential.
Sky Business Broadband vs BT Business These are natural competitors for many SMEs.
Sky Business
Full-fibre options
Digital voice
4G backup on eligible packages
Network-level security
Speed Flex on eligible services
BT Business
Broad UK availability
Full-fibre options
Business-specific broadband packages
Backup and support options depending on package
Large business connectivity portfolio
We wouldn’t choose between Sky and BT on brand.
At your postcode, compare:
Actual available technology
Estimated download speed
Estimated upload speed
Guaranteed minimum speed
Backup
Support
Contract term
Total cost

Sky Business Broadband vs Virgin Media Business Virgin Media Business is particularly worth comparing where its network reaches your premises.
We think this comparison becomes most interesting when raw download speed is a priority.
Sky’s advantage can be the combination of broadband with its business continuity and voice features.
But neither provider should be chosen based on national headline speeds.
Compare the actual connection each can install at your premises.
Sky Business Broadband vs Vodafone Business Vodafone is another important Sky alternative and we think Vodafone becomes particularly interesting if:
You already use Vodafone Business Mobile
Price is a major consideration
You want broadband and mobile services together
Sky becomes particularly interesting where you value:
Connection Pro
Integrated voice
Business security
Speed flexibility
Again, compare the actual packages rather than choosing based on provider reputation alone.
Sky Business Broadband vs a Leased Line These aren’t equivalent products and standard business broadband is shared connectivity.
A leased line provides dedicated connectivity to your business.
A leased line can offer:
Symmetrical download and upload speeds
Dedicated bandwidth
Stronger service-level agreements
Higher capacity options
Better suitability for critical connectivity
But it normally costs considerably more than business broadband.
Our view
For a small shop, salon or office, Sky Business Broadband with 4G backup may provide a sensible balance between cost and resilience.
For a 50-person office whose operations stop when the internet fails we would compare a leased line.
Read our Business Leased Line guide .
What Should You Check Before Choosing Sky Business Broadband? Before signing a contract, check:
Is FTTP available at the premises? What download speed is actually estimated?
What upload speed is estimated?
What is the Guaranteed Minimum Download Speed?
Is Connection Pro 4G backup included?
How strong is 4G coverage at the premises?
What voice lines are included?
Do you need a static IP?
Does your required speed need Speed Flex?
What security features are included?
What is the minimum contract term?
Can the monthly price change during that term?
What are the early termination charges?
Are there installation costs?
What is the total contract cost?
We think questions 1-5 matter more than the provider’s headline advertised speed.
Our View on Sky Business Broadband We think Sky Business Broadband is much more interesting as a package than it is as a simple internet connection.
If you strip away:
4G backup
Voice
Security
Speed flexibility
Static IP options
then Sky is competing primarily on price and speed against a crowded broadband market.
That’s not necessarily where we think its strongest argument lies.
The more compelling customer is a business where connectivity directly supports trading.
Consider a small café and their broadband can support:
Card payments
EPOS
Delivery platforms
Bookings
Email
Customer Wi-Fi
In that situation, automatic 4G backup has an obvious commercial value.
The same applies to a salon whose booking system and card terminal depend on the internet.
We think those are stronger Sky use cases than a one-person business simply looking for the lowest possible broadband bill.
There are limitations.
4G backup isn’t speed-guaranteed.
Full-fibre availability varies by address.
Some businesses won’t need the additional features.
And organisations with genuinely critical connectivity requirements should compare dedicated leased lines.
But for a typical UK SME wanting a recognisable provider, full fibre where available, business phone functionality and an additional layer of connectivity resilience:
we think Sky Business Broadband deserves to be on the comparison list.
Just don’t buy it because it’s Sky.
Compare what Sky can actually deliver at your premises against BT, Virgin Media Business, Vodafone, TalkTalk, Zen and any full-fibre networks available locally.

Sky Business Broadband FAQs Is Sky Business Broadband good?
We think Sky Business Broadband is particularly attractive for SMEs that will benefit from features such as full fibre, digital voice and automatic 4G backup. Businesses focused purely on price should compare cheaper alternatives, while organisations requiring dedicated connectivity should consider leased lines.
How much does Sky Business Broadband cost?
Sky Business pricing depends on your address, available connection, package, contract and add-ons. We recommend checking a current postcode-specific quote rather than relying on old third-party price lists.

Sky’s package terms state that devices connected through its 4G backup can have a maximum download speed of 80Mbps. Actual performance isn’t guaranteed and depends on factors including mobile signal, building characteristics and network demand.
Is Sky Business 4G backup guaranteed?
No. Sky explicitly states that it cannot provide a speed guarantee for the mobile connection used by the 4G backup service.
Does Sky Business Broadband include a phone line?
Relevant Sky Business packages can include digital voice lines. The number of lines and included features depend on the package.
Can I get multiple Sky Business phone lines?
Yes. Eligible packages support additional voice lines, although charges and maximum numbers depend on the service.
Does Sky Business include calls?
Current package documentation includes unlimited calls to UK landlines and mobiles on relevant services, subject to Sky’s Acceptable Use Policy and package conditions.

Speed Flex allows eligible full-fibre Pro and higher-tier customers to change the speed associated with their broadband package, subject to Sky’s terms and applicable charges.
Does Sky Business provide a guaranteed minimum speed?
Sky Business account information includes a Guaranteed Minimum Download Speed for the service. Check your contract summary for the figure applying to your connection.
Is Sky Business Broadband suitable for VoIP?
It can be suitable for VoIP, particularly on full fibre, but check upload speed, latency, backup and the number of simultaneous calls. Larger phone deployments should also compare dedicated business VoIP systems.
Is Sky Business Broadband good for card machines?
A reliable broadband connection can support IP-connected card terminals, and we think automatic 4G backup is particularly useful for businesses dependent on card payments. Always confirm your payment setup can operate correctly during backup.
Is Sky Business Broadband good for cafés and restaurants?
We think it can be a good fit where broadband supports card payments, EPOS, reservations and customer connectivity. 4G backup is particularly relevant to these businesses.
Is Sky Business Broadband good for a small office?
Yes, particularly where full fibre is available and the office can benefit from digital voice, backup and business security features.
Is Sky Business better than BT Business?
Neither provider is universally better. Compare the actual connection, speeds, backup features, support, contract and total price available at your address.
Is Sky Business better than Virgin Media Business?
It depends on availability and priorities. Virgin can be particularly competitive for high download speeds where its network is available, while Sky’s combination of connectivity, voice and 4G backup may appeal to SMEs wanting a bundled proposition.
Should I get Sky Business Broadband or a leased line?
For a typical small business, standard broadband may be considerably more economical. If your organisation requires dedicated bandwidth, symmetrical speeds and stronger service guarantees, we think a leased line is worth comparing.
What are the main Sky Business Broadband alternatives?
Alternatives include BT Business, Virgin Media Business, Vodafone Business, TalkTalk Business, Zen Business, Hyperoptic Business and dedicated leased-line providers. Availability varies by address.
