How much speed you actually need
Download speed gets the attention, but most offices use less than they think. Email, web browsing and cloud apps use little bandwidth. Video calls use more, roughly a few megabits per person in a call, and large file downloads or software updates create short bursts. A ten-person office can work comfortably on a modest plan if the network inside the building is well set up.
Rather than guessing, look at what you use today. A business firewall can show peak usage over a week. If you regularly hit the ceiling at busy times, a faster plan helps. If you rarely use half of it, faster fibre will not make anything feel quicker; the bottleneck lies elsewhere.
Why upload matters more than it used to
Many fibre plans are asymmetric, with upload much lower than download. That suited the era of downloading web pages and email. Now offices upload constantly: video from every person on a call, files syncing to the cloud, backups, scanned documents, security camera footage and large attachments. When upload fills up, calls stutter and everything feels slow.
Symmetrical plans or plans with higher upload are worth the extra cost for offices with heavy cloud backup, video production, design files or several people on video calls at once. Check the actual upload figure on each plan rather than assuming it scales with the download. Ask whether upload speeds are the same at busy times of day as in quiet periods.
Static IP addresses
A static IP address is an internet address that never changes. Residential plans usually use dynamic addresses that can change after a restart or periodically. A static address is useful if you host anything that people need to reach, such as a VPN, a remote desktop gateway, a security camera system or a server, and if your software vendors or partners allow access only from known addresses.
Many business plans include one static address or offer it as a small add-on. Even if you do not need one today, it is often worth having, because some cloud security rules, such as allowing sign-in only from the office, are much easier to set up when the office address does not change.
What business-grade support means
Business plans often come with faster fault response, priority support queues and sometimes a service level agreement, or SLA, that sets target times for fixing faults. Read what the SLA actually promises. Some commit to responding within a set time but not to fixing anything by then; others offer service credits if targets are missed, which are usually small compared with your cost of downtime.
In practice the value of business support is getting to a knowledgeable person quickly and having faults escalated with priority. Ask how faults are logged, whether there is an after-hours process and whether a technician visit is arranged for business customers ahead of residential ones. Keep the account number and fault process somewhere every manager can find it.
Contract terms and moving offices
Check the contract length, early termination fees, what equipment is included and whether you must return it. If you might move offices in the next few years, ask how relocation works: some providers move the service without penalty, others treat it as a new connection with new fees and a fresh term. Fibre installation at a new address can take weeks, so plan early.
Also ask whether the plan includes a router you have to use, or whether you can connect your own business firewall directly. Most providers support customer-owned equipment, but some settings, such as the connection type or VLAN tagging, need to be confirmed for it to work. Your IT provider can confirm those details with the provider before the connection goes live.
Comparing plans side by side
Put each option in a simple table: download, upload, static IP, support hours, fault response target, contract length, exit fees and monthly price. Add any installation charges. The cheapest plan is rarely the best value for a business that loses real money during outages, and the most expensive plan is rarely necessary for a small office.
Finally, think about pairing the main plan with a backup connection rather than paying for the top tier. A mid-range fibre plan plus a 4G, 5G or Starlink backup often gives better resilience than a single premium service, because no single fault can take both down. Review the plan each year at renewal, because offers change and your usage will have changed too.
In short
- Measure actual usage before paying for more download speed.
- Check upload capacity; it drives call quality and cloud backup.
- A static IP makes remote access and security rules easier.
- Read what the SLA actually commits to, not just its headline.
- A mid-range plan plus a backup connection often beats one premium plan.
