Business broadband typically costs two or three times the consumer equivalent, frequently over the same physical line. Understanding what the difference actually buys makes the decision straightforward.
What you are actually paying for
Fault resolution targets
The main thing. Consumer faults are fixed in due course. Business services carry a target repair time, sometimes with compensation attached.
Read what is actually promised. "Enhanced care" means a defined target. A vague statement about prioritising business customers is a marketing position rather than a commitment.
A static address
Needed if anything on your network must be reachable from outside — a VPN endpoint, a remote access system, a mail server, a camera system, or a supplier's connection that is restricted by address.
No traffic management
Consumer services may shape traffic at busy times. Business services generally do not.
Support that understands business questions
The value here varies enormously by provider. A business support line that still begins by asking you to restart the router is not worth a premium.
Speed, and the number that actually matters
Download speed is advertised. Upload speed is what limits most business activity.
Video calls, cloud backups, sending large files, synchronising to cloud storage, and anything hosted on site all depend on upload. A connection advertised as 900 megabits down with 100 up will feel fast when browsing and struggle when four people are on video calls while a backup runs.
Symmetric connections — the same speed both ways — are considerably better for business use, and they are what leased lines and some full fibre products provide.
Contention
Most connections share capacity with other users. Contention describes how many, and it is why speeds drop in the early evening on residential services.
Business services are typically less contended. Leased lines are not contended at all, which is part of what you pay for.
In practice, for an office of ten people on a full fibre business connection, contention is rarely the constraint. It matters more on older technologies.
Leased lines: when they are worth it
A leased line is a dedicated, symmetric connection with a contractual repair time, usually measured in hours.
They cost substantially more than fibre broadband and are worth it when: you need guaranteed symmetric bandwidth, downtime costs you significantly per hour, you host services on site that customers depend on, or you have a contractual obligation to a specific level of availability.
They are not worth it when a good fibre broadband service would do and the money would be better spent on a second connection for resilience. For many small businesses, two diverse connections give better real-world availability than one excellent one — because most outages are physical faults, and a second line on a different technology is unaffected.
Resilience usually beats raw speed. A business with two ordinary connections is online more hours per year than a business with one exceptional one.
Designing for outage
Ask what an hour of no internet costs you. For a business running on cloud services, it is close to a full stop — no email, no accounting, no phones if you use IP telephony.
The practical arrangement:
A primary connection, fibre where available.
A secondary on different infrastructure. A mobile connection is ideal because it fails independently — a digger through a duct does not affect it. Two providers reselling the same underlying line do not give you resilience, which is worth checking before you buy.
Automatic failover. A firewall or router that switches without anybody intervening, and switches back afterwards.
Testing. Unplug the primary, deliberately, during a quiet period. Failover configured and never tested regularly turns out not to work.
Also consider what fails with the internet. If your phones are IP-based, an outage takes your phone number too. Mobile diversion arrangements should be agreed with your provider in advance rather than arranged during an incident.
What to check before signing
- What is the contractual repair time, and what is the compensation if it is missed?
- Is the upload speed adequate for your actual use?
- Is a static address included?
- What is the contract length, and what does it cost to leave?
- Is the price fixed, or does it rise mid-contract?
- Who owns the router, and can you use your own?
- What underlying infrastructure is it on, and does your backup use different infrastructure?
That last question is the one most often unasked, and it is the one that determines whether your resilience is real.
Rural and coastal considerations
Availability varies considerably across Suffolk and Norfolk. Where full fibre has not arrived, options may be limited to older technologies, fixed wireless from a local provider, or business mobile connections.
Fixed wireless can be excellent where the line of sight is good. Mobile connections have improved substantially and are viable as a primary service in some locations, particularly with an external aerial.
It is worth checking what is genuinely available at your postcode rather than assuming, because provision changes and providers do not always advertise well locally.
