How Fast Should My Business Internet Be?

For most small businesses, a 200 Mbps internet connection is more than enough.

But speed alone is a poor way to choose a business internet connection.

A five-person online retailer, a 20-person office using cloud storage and VoIP, and a 50-seat call centre may all depend heavily on the internet, but their requirements can be completely different.

The right connection depends on what your business actually does, how many people use it, which applications you rely on, how much data you upload as well as download, and what would happen if your connection stopped working altogether.

So rather than simply asking, "Is 200 Mbps enough for my business?", the better question is:

"How does my business actually use the internet, and what connection do I need to support it properly?"

Is 200 Mbps Enough for a Small Business?

In most cases, yes.

As a practical starting point, I often work on around 10 Mbps per person for a typical small business. It isn't an industry formula or a hard rule, and it doesn't scale indefinitely, but it provides a useful place to begin.

For a business with 10 to 20 employees, a 200 Mbps connection would usually provide plenty of capacity, with some room to grow.

But headcount alone doesn't tell you very much.

A 20-person business primarily using email, web applications and basic cloud services might operate comfortably on 100 Mbps. Another business with exactly the same number of employees could be constantly synchronising large files, performing cloud backups, making VoIP calls, hosting video meetings and supporting remote workers.

The number of people is the same. The way they use the connection isn't.

That's why my first question wouldn't be:

"How many employees do you have?"

It would be:

"What exactly does your business do?"

Start With How Your Business Actually Works

Consider an online retailer.

Its entire business may depend on the internet. The website, ecommerce platform, payment processing, stock management and customer communications could all be cloud-based.

But does that automatically mean it needs an extremely fast internet connection?

Not necessarily.

If employees are mainly accessing web-based systems, processing orders and sending emails, the actual bandwidth requirement could be relatively modest.

Now compare that with a call centre.

Dozens of employees may be making simultaneous VoIP calls. The raw amount of bandwidth required for each individual call isn't necessarily huge, but the quality and management of the connection become extremely important. Voice traffic needs to travel reliably in both directions and should be prioritised so that someone downloading a large file doesn't suddenly affect everyone's phone calls.

Before recommending a connection, I would want to understand the systems behind the business.

Does it use cloud document storage? How many people regularly synchronise files? Does it perform large cloud backups? Does it use VoIP or cloud-connected CCTV? Are there remote workers connecting back into the office?

Even the way remote employees work can completely change the answer.

Someone connecting to a remote desktop in the office may use relatively little bandwidth. Someone using a laptop that continuously synchronises large files with a server in the office could have a much greater impact on the connection.

The details matter.

My Rule of Thumb: Start at Around 10 Mbps Per Person

If I had to give a simple starting point, I would use around 10 Mbps per person.

Very roughly, that means a 10-person business might be comfortable with 100 Mbps, while a 20-person business might look towards 200 Mbps.

But this should never be treated as a bandwidth calculator.

A business with ten graphic designers regularly transferring enormous files could need considerably more bandwidth than an office of 30 people mainly using email and web applications.

The rule also stops scaling neatly as businesses become larger.

Once you reach around 50 users, I would probably start considering gigabit connectivity. At around 200 users, 10 Gbps connectivity may become a consideration, depending entirely on the organisation, its infrastructure and what those users are actually doing.

At that size, you're no longer trying to calculate the absolute minimum connection the business can survive on. You need to consider growth, fluctuations in demand and the operational impact of running out of capacity.

There is also a commercial consideration.

With dedicated leased lines, the price difference between different bandwidth levels can sometimes be relatively small. As an illustrative example, you might find a 100 Mbps leased line costs around £150 per month while a full gigabit service costs closer to £300, although actual pricing varies significantly by provider, location, contract length and installation requirements.

If you're already paying for dedicated connectivity and expect the business to grow, buying additional headroom can make considerably more sense than trying to precisely calculate the minimum speed you can get away with.

Why Upload Speed Matters More Than It Used To

Go back 10 or 15 years and the way businesses used the internet was very different.

Most businesses were primarily downloading.

You downloaded software and installed it locally. You downloaded documents and worked on them on your computer. Traditional ADSL and early fibre broadband products reflected this, offering much faster download speeds than upload speeds.

Modern businesses increasingly work in both directions.

Documents are stored and synchronised using platforms such as SharePoint and Dropbox. Cloud backups continuously send data away from the business. VoIP and video meetings require two-way communication. CCTV footage may be uploaded for remote viewing or cloud storage.

A connection with a fast download speed but poor upload performance can therefore become a significant bottleneck.

Imagine an employee edits a large document and saves it to cloud storage. If the upload speed is slow, it could take several minutes before the new version has fully synchronised.

Meanwhile, a colleague could be waiting to open and edit that same document.

That's when you start seeing synchronisation conflicts, outdated copies and confusion about which version is current.

A fast download speed is still important, but for a modern cloud-based business, it is only half the story.

Why a Fast Connection Doesn't Guarantee Good VoIP Calls

VoIP is a good example of why headline speed doesn't tell you everything.

A phone conversation is bi-directional. You need to hear the other person, and they need to hear you.

But in my experience, bandwidth itself often isn't the reason for poor VoIP quality.

We've encountered businesses where calls sound robotic, distorted or broken up. The immediate assumption is usually:

"Our internet isn't fast enough."

But nine times out of ten, the solution isn't necessarily to buy more bandwidth.

It may be a Quality of Service, or QoS, problem.

QoS allows a properly configured firewall or router to prioritise important traffic. A voice call is highly sensitive to delay, while a software update or large file download can usually wait a fraction longer without anyone noticing.

Without that prioritisation, one employee downloading or uploading a large file could potentially affect the quality of everyone's calls.

This is one of the most important lessons when looking at business connectivity:

The answer isn't always more bandwidth. Sometimes, it's better management of the bandwidth you already have.

Why You Might Not Always Get the Advertised Speed

If you pay for a 200 Mbps connection, it's easy to assume you should always receive 200 Mbps.

The reality can be more complicated.

Many standard broadband services use shared network infrastructure. Depending on the provider and product, contention ratios may range from 1:8 to 1:20 or higher.

But contention can be difficult to explain without getting unnecessarily technical, so I use a simple analogy.

Imagine you're sitting at a beach bar and the waitress brings over an enormous cocktail with ten straws.

If you're the only person drinking it, that cocktail might last 15, 20 or 30 minutes.

Now imagine nine friends arrive. Everyone grabs a straw and starts drinking as quickly as they can.

The cocktail disappears considerably faster.

That's the basic idea behind contention.

You're sharing an underlying resource with other users. It doesn't mean a 1:8 contended connection will automatically run at one-eighth of its advertised speed, but it does mean the headline capacity isn't necessarily reserved exclusively for your business at all times.

A dedicated leased line is different. These services are typically provided with uncontended 1:1 bandwidth, where the capacity is dedicated to your connection.

So a 1 Gbps standard broadband connection and a 1 Gbps leased line may have the same headline number, but they aren't equivalent products.

The Internet Isn't Always the Problem

One of the most common things we hear is:

"The internet is down."

Sometimes it is.

But very often, the internet connection itself is working perfectly well.

The problem is the Wi-Fi.

The two terms are often used interchangeably, but they're not the same thing. Your internet connection brings connectivity into the premises. Your Wi-Fi distributes that connectivity wirelessly around the building.

You could have a perfect gigabit internet connection and still experience terrible performance because of poor Wi-Fi coverage.

An employee might be ten metres from an access point but have walls, interference, building materials or other devices affecting the signal. Move directly underneath the access point, and suddenly everything appears fast again.

This is something we see regularly in the real world.

A business experiences slow connectivity, assumes it needs a faster internet connection and considers upgrading from 200 Mbps to 1 Gbps.

But if Wi-Fi is the bottleneck, that upgrade may make absolutely no difference.

You could end up paying for five times more bandwidth while experiencing exactly the same problem.

Your Router or Firewall Could Be Limiting Your Connection

Wi-Fi isn't the only potential bottleneck.

The equipment handling your internet connection also matters.

Many low-cost broadband services include a basic router. It needs to function, provide connectivity and be inexpensive enough for the provider to supply at scale.

For a home user or very small business, that may be perfectly adequate.

As businesses grow, however, they often need more capable business-grade routers and firewalls that provide greater control over security, traffic management, QoS, VPN access and network performance.

Throughput is particularly important.

Imagine you're paying for a 1 Gbps internet connection, but your firewall can only process 200 Mbps when features such as stateful packet inspection are enabled.

You're paying for five times more bandwidth than your firewall can actually handle.

VPNs can introduce another limitation. A firewall might support high general network throughput but have considerably lower encrypted VPN throughput.

Before paying to upgrade your internet connection, it's therefore worth asking:

Can the rest of your network actually handle the speed you're buying?

200 Mbps Broadband and a 200 Mbps Leased Line Are Not the Same Thing

This is where the question of whether 200 Mbps is enough becomes more complicated.

A cheap 1 Gbps FTTP broadband connection might have a much higher headline speed than a 200 Mbps dedicated leased line.

Does that automatically make it better?

No.

A standard FTTP service might cost £30 or £40 per month and offer impressive speeds, but it may use shared infrastructure and come with repair targets measured in days rather than hours.

If something goes wrong, you could be relying on best endeavours to restore the service.

A dedicated leased line might cost £200, £300 or £400 per month, but you're paying for a fundamentally different level of service.

Depending on the provider and product, that can include:

• Dedicated, uncontended 1:1 connectivity.
• Service levels measured in hours rather than days.
• Better support and escalation routes.
• Fixed IP addressing.
• Options for managed failover or backup connectivity.

So which is better: a 1 Gbps FTTP connection or a 200 Mbps leased line?

The answer depends on what downtime means to your business.

If losing internet for two or three days would be inconvenient but manageable because employees could work from home or elsewhere, the cheaper broadband connection may be entirely adequate.

If every employee immediately becomes unable to work, your phones stop functioning, customers can't reach you and the business starts losing money, the calculation is completely different.

A faster connection isn't automatically a better business connection.

How Much Internet Resilience Does Your Business Actually Need?

The right level of resilience shouldn't be determined purely by the number of employees you have.

It should be determined by the impact of an outage.

For a business with one to five people, the backup plan might simply be hotspotting from mobile phones. If that's enough to keep everyone working, there may be no commercial reason to pay for anything more elaborate.

As a business grows, a dedicated primary connection with a basic broadband or mobile service as backup may make sense.

Larger or more internet-dependent organisations might use dedicated connections from two separate providers.

But even that isn't necessarily true resilience.

Two connections from different providers could still travel through the same physical duct underneath the same road. If a workman digs through that duct, both services could disappear at once.

Businesses that require greater resilience may therefore consider genuinely diverse connectivity, where connections use separate physical routes.

Satellite connectivity can provide another option. Because it doesn't depend on the same local underground infrastructure, it can offer useful protection against events such as local cable damage.

The important question isn't:

"What's the most resilient internet setup I can buy?"

It's:

"What would an internet outage actually cost my business?"

If your connection disappeared tomorrow, could employees work from home?

Could they work from another office?

Could a small team hotspot from their phones for a day?

Or would the entire business immediately stop operating?

The answer should determine how much resilience is commercially justified.

Don't Buy Only for the Business You Have Today

Internet contracts can be long.

A dedicated connection might tie you into a two-, three- or sometimes even five-year agreement. Some standard broadband services also come with significant minimum terms.

So don't just consider how many employees you have today.

Think about where the business might be before that contract ends.

As a practical guideline, I would aim for around 20% more capacity than you believe you currently need, particularly if you're expecting growth.

Using the rough 10 Mbps-per-person starting point, a 20-person business might theoretically look towards 200 Mbps. If the company is growing, I might instead consider a 300 Mbps connection.

Again, pricing matters.

With some dedicated connectivity products, both a 200 Mbps and 300 Mbps service may be delivered over underlying infrastructure capable of supporting 1 Gbps. The price difference between the two can therefore be relatively small.

In that situation, buying additional headroom can make more sense than risking outgrowing the connection while still tied into a long-term contract.

So, How Fast Should Your Business Internet Actually Be?

For most small businesses, 200 Mbps is enough.

But the headline speed is only one part of the decision.

A 20-person office mainly using email and web applications could comfortably need less. A smaller company constantly transferring huge files, running cloud backups or supporting demanding remote workflows could need considerably more.

Start by understanding what the business actually does.

Look at the number of users, but also look at cloud storage, backups, VoIP, video calls, remote access, CCTV, upload requirements and future growth.

Then consider the connection itself.

Is it contended or dedicated? What happens if it fails? How quickly will it be repaired? Could employees continue working elsewhere? Do you need a backup connection? And can your existing firewall, network and Wi-Fi actually support the speed you're buying?

As a rough starting point, I would consider around 10 Mbps per person, with additional headroom for growth. But that should guide the conversation, not replace it.

The real decision for most businesses isn't simply whether 200 Mbps is fast enough.

It's whether you need standard broadband, a dedicated leased line or additional resilience.

If being without internet would seriously affect your ability to operate, the extra cost of a dedicated connection and suitable backup may be easy to justify.

If your employees could simply work from home, hotspot from mobile devices or work elsewhere for a couple of days, a standard business broadband connection may be entirely sufficient.

Don't buy the biggest number because it sounds better. Buy the connection that fits how your business actually works.
