Starlink vs 5G – Which is faster in the UK?

5G is faster than Starlink on average in the UK, but not by much. In cities with strong mobile coverage the gap is more noticeable. In rural areas where mobile signal is weak or unavailable, Starlink is usually the stronger option. The data backs this up and we will get into the exact figures in the speed comparison section below.

But speed figures alone do not tell the full story, especially for businesses. Here is what the data actually shows and what it means for how your business connects.

What Is The Difference Between Starlink And 5G?

Before getting into speed figures it is worth understanding what each technology actually is, because the difference matters more than most people realise.

Starlink is a satellite internet service operated by SpaceX. Your dish points up at space and connects to a network of satellites in Low Earth Orbit, which then beam internet down to you. Because the satellites orbit much closer to Earth than older satellite systems, latency is significantly lower than traditional satellite internet. Starlink works anywhere it can see the sky, which makes it particularly useful in rural and remote locations where ground based infrastructure simply does not reach.

5G is the latest generation of mobile network technology. A 5G router connects to the same mobile towers that your phone uses, via a SIM card. It works anywhere with a strong mobile signal, which means it performs best in cities and urban areas where mobile infrastructure is densest. In rural areas with limited mobile coverage, 5G performance drops off sharply or may not be available at all.

Both are shared networks. Neither gives you a dedicated uncontended connection, which is an important point for business use that we will come back to.

Which Is Faster, Starlink Or 5G In The UK?

The speeds are closer than most people expect. According to Ookla’s independent speed testing, the UK median Starlink download speed was 106.63Mbps in Q3 2025. The UK average median 5G download speed was 111.07Mbps according to Ookla’s H2 2024 study, the most recent UK wide average available. On those figures 5G comes out ahead but only a little.

The bigger difference is not in the averages though. It is in what each technology delivers depending on where you are.

In cities and urban areas with strong 5G coverage, speeds can be considerably higher than the national average. In rural areas where mobile coverage is limited or absent, Starlink is often the only option that can deliver broadband level performance at all.

Upload speed is where another gap shows up. Both Starlink and 5G deliver upload speeds that are considerably lower than their download speeds, which matters for businesses pushing data to the cloud, running hosted systems or making video calls. Neither is a symmetrical connection. For a deeper look at Starlink’s speed performance specifically, see our article on the most reliable alternative to Starlink.

How Does Starlink Speed Compare To 5G In Different Parts Of The UK?

This is where the comparison gets more useful for businesses making a real decision.

Where 5G Wins In Cities And Urban Areas

5G has the clear advantage in well covered urban locations. Mobile infrastructure in UK cities is dense and competition between operators drives performance. Where 5G coverage is strong it can deliver speeds well above the national average. Starlink works in cities too but its performance is affected by the same shared network congestion that affects users everywhere, and in some high demand areas like London and the South East there are additional pressures on the network.

Where Starlink Wins In Rural And Remote Locations

Starlink’s advantage is biggest in locations where 5G simply is not available. In rural settings, remote facilities and locations far from mobile towers, Starlink can deliver consistent broadband level speeds regardless of what ground based infrastructure exists nearby. For businesses operating from these kinds of sites it is often the only practical wireless option.

What About Starlink Speeds In London?

London is an interesting case. 5G coverage in the capital is available but Ookla data from Q1 2025 showed London’s median 5G download speed at 115Mbps, which actually lagged behind other UK cities. Glasgow recorded 184.99Mbps in the same period. Starlink in London and the South East faces its own network demand pressures too, meaning neither is a guaranteed high performance solution in the capital without the right setup behind it. 

Why Speed Alone Does Not Make Either Option Right For Business

Both Starlink and 5G are shared networks. Every user drawing from the same network at the same time is competing for the same capacity. The speeds quoted in any comparison article, including this one, are averages. What your business actually gets at 10am on a Tuesday when everyone is online and working is a different story.

Neither comes with a service level agreement that commits to a minimum speed or a fix time if something goes wrong. For a home user that is fine. For a business where a slow connection costs real money, it is an entirely different calculation.

The question for any business should not be which is faster on paper. It should be which one will behave consistently when your team needs it to, and whether either is genuinely capable of carrying your operations on its own.

Is 5G Or Starlink Better For Business?

It depends on your location and what your business actually needs from its connection, but there is one thing worth saying upfront about both of them. Neither is built for heavy business data use on its own.

5G is a metered connection. Costs are tied to usage and for businesses that push a lot of data through their connection every day, those costs can become difficult to predict and control. It works well for businesses with moderate usage, or as a backup connection that only carries traffic when the primary goes down. We offer 4G and 5G business broadband with partnerships across all UK mobile carriers, which means we can identify the best performing network for your specific location rather than locking you into a single provider.

Starlink’s priority business service is also metered. Once the priority data allocation runs out, performance drops sharply. For businesses with unpredictable or high data demands, that creates the same budgeting problem as 5G.

If you are in a rural or remote location where 5G is simply not available, Starlink is the more practical choice for getting broadband level speeds. APC Solutions specialises in non standard Starlink installations for sites with limited power availability, restricted mounting options or environments where standard kit will not work.

What If Neither Is Enough On Its Own?

Some businesses find that the answer is not choosing between Starlink and 5G but using both together intelligently. APC Solutions can bond multiple connection types into one setup so that each one carries the load the other cannot. When 5G congestion builds, Starlink steps in. When Starlink latency climbs, 5G picks up the real time traffic. The cost monitoring and traffic controls that APC puts in place mean you are not left with a surprise bill at the end of the month either.

It is a different approach entirely. Less about finding one connection that does everything and more about building a setup that holds up whatever your business faces. 

How Starlink And 5G Compare For UK Business Use

The numbers do not tell the full story. Here is how Starlink and 5G stack up across the things that matter most for business use in the UK.

Find The Right Connection For Your Business

Speed is just one part of the picture. Whether you are in a city with strong 5G coverage, a rural location where Starlink is the only practical option, or somewhere in between, the right setup depends on what your business actually needs and how much it can afford for that connection to let it down.

We work with businesses across the UK to design connectivity solutions that fit the location, the budget and the operational demands. Whether that means 5G, Starlink, a bonded setup or something else entirely, we will find out what works and get it in place.
