What broadband speed is considered slow?

Understanding your internet speed helps you maintain smooth operations. While many factors can slow your internet, pinpointing the exact cause often challenges even experienced users. Generally speaking, download speeds below 25Mbps create noticeable problems – though this will depend on the number of devices using the connection at one time, and what they will be doing. A good rule of thumb is: up to ten simultaneous users typically work well with 100 Mbps connections. Email and light browsing are obviously less intensive then downloading of large files or video calls or streaming. At slower speeds, you’ll struggle to connect multiple devices, share files, or maintain stable video calls. Your internet connection works through various components and technologies that must sync perfectly to keep you online, and we’ll go into some of these below.

Test your UK business broadband speed instantly (upload, download, ping, jitter)

By using the tool above, you can easily see your internet download speeds at a glance. It’s worth considering if your Wifi network (router, devices, extenders and their physical arrangement) can be optimised with the current business broadband contract you have, or whether it’s worth switching to a new business broadband contract and getting a better download and upload speed at the source. In most cases, the easiest fix is simply to change or upgrade your contract, and in many cases you can save money whilst doing so.

Download speed and upload speed

Your connection provides two distinct speeds – downloading for receiving files like documents and images, and uploading for sending them.

Optimising your Wifi network

WiFi performance changes based on your environment. Where you place your router affects your connection quality. The signal weakens as you move away from your router, while walls, floors, and other physical barriers interfere with transmission. Keep your router away from obstacles, minimise surrounding clutter, and avoid placing it behind doors or thick walls. Electronic devices and network congestion from multiple users can also degrade your connection quality.

Your hardware influences your internet speed. Traditional broadband contract-provided hardware (i.e. the router you get for free with your contract) loses effectiveness over distance, causing slower speeds and connection dropouts. Older routers often fail to manage multiple connected devices and data transfers effectively. Budget-friendly routers typically use slower CPUs and less memory, which limits their performance. Newer custom routers (i.e. ones you buy separately from the one your broadband provider) are usually far more powerful, with larger, dedicated CPUs and large antenna arrays.

Many businesses ask about WiFi boosting apps, but no legitimate application can actually enhance your WiFi signal. However, you can improve your connection by moving devices closer to your router, switching providers, resetting your connection, or managing user access during peak times. Small businesses with up to ten simultaneous users typically work well with 100 Mbps connections.

Wired Ethernet and broadband speed

For maximum performance, consider switching to a wired connection. While it might seem outdated, Ethernet cables transfer data faster than WiFi because they don’t need to encrypt information like wireless connections do. This direct connection often provides the most reliable solution for businesses requiring consistent, high-speed internet access.

Software downloads and broadband speed

Keep an eye on your software usage too – some programs and apps demand more bandwidth than you might expect – a good example being Adobe Creative Suite – if you have a number of Adobe Creative Suite programs downloaded to your machine, like After Effects or Photoshop, each software update can be gigabytes in size, and will trigger downloads automatically. Close unnecessary background applications and only run resource-heavy programs when needed.

Do I have a bandwidth cap?

Your provider might limit your data through bandwidth caps, restricting your upload and download capacity. This affects businesses operating online around the clock. If your current business broadband contract includes bandwidth caps, you should absolute move to a contract with no caps or restrictions. You will want unlimited data with your business broadband contract so you never need to worry about limitations on data or speed.

VPNs and broadband speed

VPNs encrypt connections between your devices and servers, hiding your IP address and strengthening security. However, VPN speeds can drop during peak usage periods due to traffic congestion through relay servers. Network slowdowns also occur when too many devices connect at once, creating bottlenecks that reduce your broadband speed.

Broadband speed and connection type (ADSL, Fibre, Cable, Leased lines)

The UK offers several internet connection types, all following a similar pattern. A cable runs from your local BT Telephone Exchange to a Cabinet before connecting directly to your business, either underground or through overhead systems. The main differences lie in the cable types used. Modern fiber-optic cables have largely replaced copper ones, offering greater capacity and better performance over longer distances.

ADSL broadband

ADSL represents the oldest and slowest UK connection type. The basic ADSL1 uses copper lines throughout, delivering maximum downloads of 8Mbps. Its upgraded version, ADSL2+, uses the same copper infrastructure but enhanced technology pushes speeds up to 24Mbps, though distance affects performance.

Fibre-optic broadband

Fibre-optic internet has become the UK’s most popular choice. This technology incorporates fibre cables somewhere between your provider and your business location. These cables withstand harsh weather better than traditional options, reducing service interruptions.

Cable broadband

Cable broadband connects your business to a local fiber cabinet using coaxial cables instead of copper phone lines. This delivers faster speeds than traditional connections. Virgin Media and select local providers offer this service, sometimes called Hybrid Fiber-Coaxial Connections.

Leased line broadband

Leased lines work differently from standard broadband by providing your business with its own dedicated connection. Unlike sharing bandwidth with nearby users, you rent an exclusive line that delivers consistent speeds and improved efficiency. This private network maintains high service levels without interruptions, making it ideal for large offices, frequent VoIP users, heavy data transfers, or businesses running high-traffic websites.

Do malware and viruses affect broadband speed?

Malware and viruses often consume high bandwidth, dragging down your internet speed. Strong antivirus software protects your network from hackers and prevents malicious programs from stealing resources. Your connection might also slow down when your business needs outgrow your current plan. Contact your provider to review your package and check if you need more bandwidth to support your operations.

Switch broadband supplier

In so many cases, the easiest, and often cheapest option is simply to switch business broadband provider and contract, providing you with much faster upload and download speeds, SLAs for service guarantees (like uptime and speeds), and often a cheaper monthly cost. Don’t worry about the admin hassle of switching providers, in many cases the new supplier will handle the hassle of the switchover process.

Use the tool above to instantly test your internet speed – measuring your download speed, upload speed, ping and jitter.

What is considered fast broadband? What is considered slow broadband?

You can take your tested download speed and compare it to the figures on the table below for representative maximum download speeds depending on your particular broadband connection type:

Bear in mind that the figures above are theoretical an no broadband connection will ever reach its theoretical max speed.

Optimise existing internet setup or switch broadband provider?

The question then arises: do I switch broadband provider or attempt to rescue my current internet setup? If you choose to optimise your existing setup, here are some tips to try.

Wired Ethernet connections are faster and more reliable than Wifi

Wherever possible, connect directly through Ethernet cables since WiFi speeds decrease significantly with distance from your router. If you use laptops (that rarely have ethernet ports), dongles and adapters are cheaply available to give your devices an wired ethernet connection.

Consider where your Wifi router is positioned

If you must use wireless connections, carefully position your router to minimise signal interference from walls and obstacles. Larger offices can benefit from a mesh network system, deploying multiple routers to ensure consistent coverage throughout your space. Consider upgrading to newer router models or implementing advanced networking solutions like SD-WAN to enhance overall performance.

Consider Wifi repeaters/range extenders or a Wifi mesh network

Range extenders simply rebroadcast your existing WiFi signal, creating a second network name alongside your original router’s network. They relay traffic between these networks without any intelligent management.

Mesh systems work differently, offering a complete WiFi solution that replaces your current setup rather than adding to it. While you can technically use mesh networks with your existing router, most businesses choose to implement them as standalone systems. Mesh technology eliminates the complexity of router-and-extender combinations by deploying identical units throughout your space, working together as a single, seamless network.

Use 4G or 5G backup for your broadband

Protect your operations by implementing some level of redundancy. Small businesses often benefit from 4G and 5G-enabled routers that automatically switch to mobile broadband if the primary connection fails. Larger organisations typically prefer a secondary tethered connection, which not only provides backup but can also help balance network load – for example, by routing guest WiFi traffic through the secondary connection to preserve primary bandwidth for critical operations.

Switch broadband providers to business broadband robust SLAs around speed and uptime

Think ahead when selecting your business broadband contract and provider. Choose a scalable connection that can grow with your business, allowing quick bandwidth adjustments as your needs evolve. As your network becomes more complex, implementing network monitoring tools becomes increasingly important to maintain optimal performance.

Hybrid fibre-coaxial (HFC) broadband

HFC broadband creates a powerful connection by combining fibre optic and coaxial cables. Your internet service provider connects their central office to optical nodes using fibre optic cables, then uses coaxial cables to link these nodes directly to your business.

Asymmetric digital subscriber line (ADSL) broadband

Many UK businesses opt for ADSL broadband because it offers a cost-effective solution, particularly for small and medium-sized operations. This technology delivers internet access through existing copper telephone lines, making it widely accessible across the country.

Fibre to the premises (FTTP) broadband

When your business demands the highest performance, FTTP broadband delivers unmatched speed and reliability. By running fibre optic cables straight into your building, FTTP provides ultra-fast symmetric speeds for both uploads and downloads, significantly outperforming ADSL. This makes it particularly valuable for larger businesses and those with substantial data requirements.

Fibre to the cabinet (FTTC) broadband

FTTC broadband strikes a balance between performance and cost, making it a popular choice for many businesses. This technology runs fibre optic cables to your street cabinet, then connects to your premises via copper wires. Small to medium-sized businesses often find FTTC meets their needs for faster upload and download speeds.

Single order generic ethernet access (SOGEA) broadband

For businesses requiring dedicated bandwidth, SOGEA broadband offers an attractive solution. While it resembles FTTC by using fibre optic cables to connect the local street cabinet to your provider’s network, SOGEA sets itself apart by providing uncontested bandwidth. This means your business won’t share its connection with other local users, resulting in more consistent and reliable speeds. Larger businesses running data-intensive applications particularly benefit from this dedicated connection.

Leased line or direct internet access (DIA) broadband

A leased line, also known as Dedicated Internet Access, connects your business directly to the internet through a private connection that runs straight to your building. This dedicated service delivers consistently high performance since you don’t share bandwidth with other users, ensuring your speeds remain reliable even during busy periods. You’ll also benefit from matching upload and download speeds, allowing your business to send and receive data with equal efficiency.

Wireless mobile 4G and 5G broadband

Mobile broadband networks using 4G and 5G technology deliver internet access through cellular signals. Many businesses rely on this service as a backup connection to ensure continuous operations, while others choose it as their primary connection in locations where traditional fixed-line services perform poorly.

Wireless internet service provider (WISP) broadband

Fixed wireless broadband providers (WISPs) match the high speeds and quality of traditional broadband services but transmit data through the air rather than underground cables. This wireless approach eliminates the need for conventional telephone lines while maintaining reliable internet connectivity.

UK broadband speeds by connection type

Your choice of internet connection technology directly determines your business’ broadband speed. Different technologies across Britain deliver varying performance levels, with each option offering unique speed capabilities and coverage areas.

UK business broadband FAQs

What are the benefits of business broadband vs home broadband?

Here are the main benefits of business broadband in brief:

	Business broadband	Home broadband
Uptime SLAs
Dedicated IP Addresses
Managed Services
Network Prioritisation

What is a business broadband SLA?

Service-level agreements (SLAs) in business broadband contracts establish clear performance commitments between providers and their customers. These agreements specify how your provider must deliver key services, including guaranteed connection speeds, uptime, and latency targets. The SLA outlines exactly how your provider will respond to service disruptions, when they must resolve issues, and what compensation you can claim if they fail to meet these standards.

Business broadband SLAs typically cover five essential areas. Your provider must meet their committed installation date, clearly stating what compensation you’ll receive if they fail to do so. They will guarantee specific service availability levels, often promising 99.9% uptime throughout the year – this allows for approximately 9 hours of potential downtime annually. Your SLA will also specify network latency guarantees, with SoGEA and full fibre services near exchanges potentially offering speeds under 20ms, while leased lines may deliver even faster responses below 10ms.

When service interruptions occur, your agreement will specify how quickly your provider must restore your connection and what compensation they owe you for missing these targets. The SLA also defines the customer service standards you can expect, including support hours, response times, available communication channels, and steps you can take to escalate unresolved issues.

Do I need an SLA?

Your business needs reliable internet to thrive, and a service-level agreement protects this essential connection. By establishing clear performance standards, your SLA holds your provider accountable and gives you options when service falls short of promised levels. This contractual protection guarantees your connection’s reliability and performance, offering peace of mind for your business operations. Many providers include these agreements as part of their premium business broadband packages.

Should I get a static IP address or a dynamic IP address?

Internet protocol (IP) addresses are unique numerical identifiers for every device that connects to the internet.

A static IP address remains constant, permanently linked to a specific device or network. Dynamic IP addresses work differently, changing automatically each time a device establishes an internet connection.

Organisations can choose between static and dynamic IP addresses, each offering distinct advantages. Let’s explore how these two options differ and which might better suit your needs.

Advantages of static IP addresses:

Static IP addresses offer several important advantages for businesses. They enable consistent access to your hosted websites and servers from external locations, while also providing reliable connections for employees who need to work remotely. Your organisation can enhance security by implementing stronger remote access protocols and firewall rules with a static IP. Additionally, if you maintain your own email server, a static IP helps ensure reliable email delivery and reduces the risk of your messages being marked as spam.

Advantages of dynamic IP addresses:

Dynamic IP addresses typically suit users with simpler IT needs or limited budgets. Most internet service providers assign dynamic IPs to residential properties as standard practice. This option often proves more cost-effective than static IP addresses, making it particularly attractive for homes and small businesses that don’t require advanced networking features.

What is business broadband throttling?

Broadband providers sometimes deliberately slow down internet speeds through bandwidth throttling to maintain fair service across their network, particularly during congested periods. They typically target data-heavy activities first, including video streaming, torrenting, and large file transfers. In exceptional circumstances, like extreme network congestion or maintenance work, providers might reduce all bandwidth regardless of usage type.

However, businesses rarely experience throttling for two key reasons. First, providers prioritise business traffic over residential usage. Second, most commercial internet activity occurs during standard business hours, avoiding the peak residential traffic periods of 7-9 AM and 7-11 PM.

Is broadband throttling legal in the UK?

UK law permits bandwidth throttling, but providers must follow strict net neutrality rules. These regulations require providers to manage traffic openly and fairly, preventing them from selectively slowing specific services for commercial gain. The law allows providers to throttle connections only for legitimate purposes, such as maintaining network security, protecting network integrity, or meeting legal requirements.

Can I get a business broadband connection in my home?

Yes, you can, and it is becoming increasingly popular to do so. A business grade broadband connection delivers faster speeds than residential internet when you work from home or run a remote business. You’ll never have to share bandwidth with neighbours during peak hours – something that plagues residential users trying to run a business. For anyone who depends on reliable internet to keep their business running, upgrading to a business connection could make all the difference.

Why is business broadband more expensive than residential/domestic broadband?

You pay more for business internet because it delivers more value. Your package includes faster speeds and dedicated bandwidth, plus service agreements that guarantee quick fixes if problems pop up. Business support teams respond faster and stay with you until issues are solved – unlike basic residential support. Many providers bundle phone services with your internet too, which can save money while keeping all your business communications under one roof. The extra features and premium service might cost more upfront, but they help keep your business running smoothly when it matters most.

Is business broadband faster than residential broadband?

In almost all cases business broadband will be faster, and while you might not notice much difference when downloading emails and files, business connections really shine when it comes to uploading. You can blast files to the cloud, join crystal-clear video calls, and collaborate on shared drives without missing a beat. The faster upload speeds mean your team can work together in real-time, keeping your data secure and your workflow smooth.

Is coverage important for 4G/5G business broadband?

Depending on your location in the UK, coverage will make a substantial difference to your connection quality and speed. It’s best to check your 4G/5G coverage before committing to a business broadband contract.

How can I check 4G/5G broadband coverage?

There are various online tools to help you check 4G and 5G coverage before you buy. Here are a few:

THREE Coverage Checker

EE Coverage Checker

Ofcom Coverage Checker

Why has 4G/5G coverage suddenly dropped in the UK?

Recently, the UK’s mobile coverage for 4G and 5G has noticeably worsened. We’ve written a longer form explanation here: Why is 4G and 5G coverage so bad in the UK?

Is business broadband prioritised over residential broadband? What is prioritisation?

Generally speaking, business broadband is prioritised over residential broadband – this means business traffic does not compete with residential neighbours for example. Your bandwidth is protected, where residential connections will not be – if your neighbour is streaming shows in 4K and downloading large files, your business bandwidth will be completely unaffected. Some broadband providers explicitly state that they prioritise business over residential customers, such as BT and TalkTalk.

What is Quality of Service (QoS)?

QoS technologies keep your most important network traffic flowing smoothly, even when bandwidth gets tight. Your network knows to send high-priority data like VoIP calls first, while making sure other traffic still performs well. Think of it like a smart traffic system – it spots the emergency vehicles (your critical data) and clears a path, while keeping regular traffic moving along too.

Quality of Service can apply at the network level (via your router), or at the connection level (via your broadband provider).

Can I change bandwidth prioritisation or Quality of Service settings on my router for my network?

Your level of control over bandwidth priority or QoS will depend on what router your have. Generally speaking, most modern stock routers provided with business broadband contracts are not very sophisticated, or terribly powerful, and will default to inbuilt priority settings that you can not change. High performance routers (ones you buy separately) will almost always have sophisticated prioritisation and QoS settings.

What is symmetrical download upload speed?

A symmetrical connection delivers identical speeds for both uploading and downloading data. You’ll get the same performance whether you’re sending files to clients or downloading their feedback. Take a 200/200mbps package – you can upload those massive project files at 200mbps and pull down new assets at the same speed. This differs from asymmetrical connections, where you might zip through downloads but crawl along when uploading.

Should I bundle my business phone and broadband?

It makes a lot of sense to bundle both phone and broadband, not only are there savings to be made, but you’ll have one contract, and one point of contact for customer service. Given the prevalence of VOIP in business phone needs, phone and broadband services are ever more similar in nature.
