How fast does my office broadband need to be?
Posted on 17 July 2026 by Beaming SupportChoosing the fastest available internet connection may sound like the obvious answer, but higher speeds usually come at a higher cost. The aim is to find a connection that supports your team, customers and business systems reliably, without paying for capacity you are unlikely to use.
The right speed will depend on several factors, including:
- How many people use the connection at the same time
- The applications your team relies on
- How frequently you make video calls or transfer large files
- Whether you use cloud-based systems or online backups
- The upload speed available
- How important the connection is to day-to-day operations
The following figures provide a useful starting point, but every organisation uses its internet connection differently.
What internet speed do I need for my office?
| Office size | Number of staff | Typical internet use | Suggested connection speed |
|---|---|---|---|
| Micro office | 1–5 | Email, web browsing, occasional video calls and light use of cloud applications | 50–100Mbps |
| Small office | 6–20 | Regular cloud working, VoIP, file sharing and daily video conferencing | 100–300Mbps |
| Medium office | 21–50 | Frequent video meetings, large file transfers, cloud applications and multiple simultaneous users | 300–500Mbps |
| Large or technology-dependent office | More than 50 | Data-intensive applications, frequent large transfers, online backups and many simultaneous users | 500Mbps–1Gbps or more |
These figures are broad guidelines rather than minimum requirements. A five-person creative agency regularly uploading video files could need more capacity than a 30-person office mainly using email and browser-based applications.
For larger organisations, or businesses that depend heavily on internet connectivity, a dedicated fibre leased line may be more suitable than a shared broadband connection. A leased line provides symmetrical upload and download speeds, dedicated bandwidth and agreed service levels.
Estimated bandwidth by type of user
Another way to estimate your requirements is to consider what each person does online.
| Type of user | Typical activities | Suggested bandwidth allowance |
|---|---|---|
| Basic | Email, web browsing and light document use | 5–10Mbps |
| Standard | Cloud applications, VoIP, file sharing and occasional video calls | 10–15Mbps |
| Heavy | HD video conferencing, frequent uploads and downloads, streaming or data-intensive cloud applications | 20–25Mbps |
Do not simply multiply these figures by your total number of employees. Instead, consider how many people are likely to carry out these activities simultaneously.
For example, if 20 employees use cloud applications but only five are likely to join video meetings at the same time, your requirement may be lower than if all 20 regularly make video calls and transfer large files throughout the day.
Why upload speed matters
Broadband speeds are often advertised using the download speed, but upload speed can be equally important for a business.
Uploading data is necessary when your team:
- Makes video or VoIP calls
- Sends large files
- Saves information to cloud platforms
- Runs online backups
- Hosts services from your premises
- Transfers data between business locations
Some broadband services provide much slower upload speeds than download speeds. A leased line usually provides symmetrical connectivity, meaning the upload and download speeds are the same.
Speed is not the only consideration
A fast headline speed does not automatically guarantee a reliable experience. You should also consider:
- Reliability: How consistently does the connection perform?
- Contention: Is the available bandwidth shared with other customers?
- Service levels: How quickly will faults be investigated and resolved?
- Resilience: Does your business need a backup connection?
- Wi-Fi: Can your wireless network deliver the available speed throughout the premises?
- Support: Can you speak to knowledgeable people when you need help?
If your business would struggle to operate without internet access, reliability, resilience and fault response times may be more important than choosing the highest advertised speed.
