Is Business Broadband Worth It? Home vs Business Broadband
Business broadband costs more than residential broadband — typically £30–£70 per month versus £20–£40 for home packages — but includes features that matter in a professional context: static IP addresses, stronger SLAs, and dedicated business support. Whether the extra cost is justified depends on how your business actually uses its internet connection.

The question of whether to pay for business broadband or use a cheaper residential product is one that many small businesses face, particularly when starting out or operating from home or small shared offices. The honest answer is that it depends — but for most businesses with employees, external-facing services, or any genuine reliance on internet connectivity, the business-grade product pays for itself through the features and protections it includes.
What Is the Actual Difference Between Home and Business Broadband?
Home and business broadband can share the same physical infrastructure — particularly on the Openreach network — but differ in the service wrapper around the connection:
Static IP Address
Home broadband uses dynamic IP addresses that change periodically. Business broadband includes one or more static IP addresses, which stay constant. This matters for: hosting services that need a fixed address, configuring VPNs, remote access to office systems, many payment terminal setups, and some hosted VoIP configurations.
Service Level Agreement
Home broadband typically has a best-efforts SLA — effectively no contractual commitment to repair timeframes. Business broadband includes a defined SLA, usually targeting fault response within one working day and specifying maximum repair times. This gives you contractual recourse when things go wrong.
Dedicated Business Support
Business broadband customers typically access a separate support team with shorter wait times than consumer queues. During a fault, this matters — a business losing connectivity needs someone to answer the phone and take the fault seriously, not queue behind residential customers calling about Netflix buffers.
Contention and Traffic Management
Business broadband products often carry lower contention ratios than residential products — meaning your connection is shared with fewer other users. Some providers apply traffic management policies to residential products that deprioritise certain types of traffic during peak periods. Business products are typically exempt from these policies.
Data Allowance
Most UK home broadband products are now unlimited, so this is less of a differentiator than it once was. However, some business products include specific commitments around data that residential products do not.
How Much More Does Business Broadband Cost?
Indicative pricing comparison for similar broadband technologies:
- Home FTTC: £20–£30/month
- Business FTTC: £30–£50/month
- Home FTTP 150Mbps: £25–£35/month
- Business FTTP 150Mbps: £35–£55/month
- Home FTTP 900Mbps: £35–£50/month
- Business FTTP 900Mbps: £55–£80/month
The premium for a business product is typically £10–£20/month. For most businesses with even a handful of staff, this premium is trivially small relative to the operational risk of being on a product with no SLA and shared residential support.
When Is Home Broadband Acceptable for Business?
Home broadband used as a business connection can be acceptable in very specific circumstances:
- A sole trader working from home with no employees and no hosted services
- A secondary or backup connection at a location where the primary connection is a leased line
- A temporary or project site where a business product cannot be provisioned in time
In these scenarios, the risk profile is manageable and the cost saving may be justified. For any business with employees, client-facing systems, or genuine operational dependency on the internet, the risks of a residential product — no SLA, dynamic IP, residential support queues — are difficult to defend commercially.
Beyond Broadband: When to Consider a Leased Line
Business FTTP is appropriate for most SMEs up to around 30–40 staff with standard cloud workloads. Beyond that, or for businesses where internet downtime has a direct and significant cost, a leased line provides dedicated bandwidth and a materially stronger SLA. Leased lines start from around £69/month for 100Mbps — not dramatically more than top-tier FTTP for organisations where reliability genuinely matters.
AMVIA advises businesses on the right product for their actual requirements. For some, business FTTP is the right long-term answer. For others, the step to a leased line is justified and more cost-effective than the productivity loss from recurring broadband issues.

Frequently Asked Questions
It is not illegal, but it usually breaches the ISP's consumer terms of service. Most residential providers prohibit running a commercial operation or hosting services on a home line. The practical risks are termination if the ISP discovers commercial use, and no SLA protection when the connection fails.
Yes. A static IP is a standard inclusion in business broadband from most UK providers, and it is one of the main reasons firms choose a business product. Static IPs are needed for VPNs, secure remote access, certain card-payment terminals, and many hosted VoIP configurations that a changing home IP cannot support.
Business broadband SLAs vary by provider but typically commit to a fault-response target of one working day with defined maximum repair times. That is far stronger than consumer broadband, which carries no SLA. It is still weaker than a leased line, which commonly targets a four-hour P1 response for major faults.
Technically yes, with a static IP. In practice, business broadband upload speeds and reliability are not ideal for production web services. For anything beyond a very low-traffic internal tool, a leased line or cloud-hosted infrastructure is the better and more reliable choice.
Most business broadband runs on 12 or 24-month terms, with shorter contracts priced at a premium. Some providers offer 30-day rolling contracts at higher monthly rates, useful for temporary premises. AMVIA can identify the contract length and terms that fit your specific situation and growth plans.
It depends on team size and workload. A handful of staff on email, Microsoft 365, and the occasional call are comfortable on business FTTP. Heavy cloud backup, video, or 30-plus users start to feel contention, which is the point at which a dedicated leased line usually pays for itself.
