BT: 76–900 Mbps downloads, fast installation, owns infrastructure. Upload capped at 29–104 Mbps and support targets 'next business day'—limitations for upload-intensive operations.

Is BT Business Broadband right for your business? Yes, if you want fast download speeds (up to 900 Mbps with fibre), nationwide coverage, quick installation (10 days), and reliable infrastructure (BT owns exchange lines). But significant limitations emerge: upload speeds capped at 29–104 Mbps limit cloud operations, customer service delays reported by Ofcom, support response times only target "end of next business day." For businesses where upload speed or responsive support matter, alternatives may deliver better value.
BT stands as established, nationally recognized provider with solid reputation. Their business broadband offerings span from basic 76 Mbps to fibre packages reaching 900 Mbps. On specification sheet, this looks impressive. In practice, important limitations emerge.
This review evaluates BT Business Broadband transparently: genuine strengths, documented limitations, and when to consider alternatives.
BT's standard package offers 76 Mbps downloads (up to 19 Mbps upload). For small offices with basic connectivity needs, this suffices. For businesses wanting faster speeds, BT Full Fibre packages deliver up to 900 Mbps downloads—genuinely fast.
Real-world consideration: Advertised speeds are maximum theoretical capacity. Actual speeds vary based on:
What this means: If you're close to exchange and have moderate usage patterns, BT's advertised speeds largely achievable. If you're distant from exchange or experience heavy peak-hour demands, actual speeds may fall short of marketing claims.
BT's fundamental problem: download speeds dwarf upload speeds. Standard package: 76 Mbps down, 19 Mbps up. Even Full Fibre: 900 Mbps down, only 104 Mbps up.
This asymmetry creates operational friction:
For businesses relying on cloud productivity tools, asymmetric upload becomes genuine operational constraint—not just theoretical limitation.
The disconnect: Businesses hear "900 Mbps" and assume fast internet. They discover upload limitations only after committing. Better alternatives provide symmetric speeds where download and upload match.
BT excels in installation execution. Typical timeline: 10 days from order to live service. Existing BT customers upgrading take only 5 days. Off-site repair capability (green street cabinets) means zero on-premises disruption.
What this means: Choosing BT means minimal business disruption. You're not waiting weeks or dealing with installation crews in your offices. For businesses needing quick deployment, this advantage is real.
All BT Business Broadband customers receive BT Smart Hub 2. This router delivers substantial Wi-Fi coverage, straightforward setup ("plug and play"), and reliable performance. It's consumer-grade hardware (not enterprise), but performs well for typical business requirements.
Practical value: You don't need to source separate router or configure complex networking. BT handles hardware provision as part of package.
BT owns UK telephone exchange infrastructure. When failures occur, BT technicians repair directly—no third-party contractor delays. This direct ownership creates faster repairs compared to providers dependent on third-party infrastructure.
Service Status page provides real-time information about area-wide issues. Live chat and phone support available for outage information.
The trade-off: Direct infrastructure ownership enables faster repairs, but doesn't guarantee faster support response to initial calls (see Support Limitation below).
Ofcom's 2023 service quality report highlighted significant BT customer service gaps. Key findings:
For mission-critical business operations, "end of next business day" response time creates unacceptable exposure. Every hour of downtime costs business revenue. BT's support model doesn't prioritize rapid issue resolution.
Example impact: Internet fails at 4 PM on Friday. BT targets repair by end-of-business Saturday. 28+ hours without service. Revenue impact for connectivity-dependent business: potentially £5,600+/hour × 28 hours = £156,000+ cost.
Specialist providers often guarantee 2–6 hour response times with direct expert access, dramatically reducing downtime exposure.
BT's monthly broadband pricing appears competitive. But total cost of ownership includes support response time impact. If support delays create downtime costs exceeding monthly savings, cheaper pricing becomes false economy.
Scenario calculation: BT at £50/month, competitor specialist at £80/month. Over 24 months: BT costs £1,200 service. Competitor costs £1,920 service. Difference: £720.
But if BT's slower support causes one 8-hour outage costing £44,800 in lost productivity/revenue, while specialist's faster support prevents same outage, specialist option delivers £43,080+ value despite higher monthly pricing.
Honest cost comparison must include downtime risk, not just monthly billing.
Video-heavy businesses discover upload limitations quickly. Creative agencies uploading daily large files find 104 Mbps upload frustratingly slow. Healthcare organizations backing up patient data encounter similar constraints. Microsoft 365 cloud environments relying on OneDrive sync struggle with asymmetric speeds.
These aren't theoretical problems—they're daily operational friction.
If you're currently with BT and experiencing any of these situations, alternatives likely deliver better value:
If your business regularly uploads files, backs up to cloud, or relies on video conferencing, BT's upload limitations will create friction. Symmetric or near-symmetric speed alternatives (FTTP, specialist providers) better serve upload-intensive operations.
Calculate: if internet fails for 8 hours, what revenue/productivity loss occurs? If answer exceeds £500, BT's "next business day" support target becomes financial liability. Specialists guaranteeing 2–6 hour response justify premium pricing.
Managing broadband, VoIP phone system, mobile, and security through separate vendors creates complexity. Specialist providers offer integrated solutions reducing vendor coordination and support complexity.
BT routes support through centralized systems. Specialist providers provide direct access to technical decision-makers. When issues require rapid escalation, direct expert contact saves time.
If you're considering BT Business Broadband, honestly assess your upload requirements and support response time needs. For basic operations with low uptime criticality, BT delivers reasonable value.
If your business depends on fast uploads, integrated communications, or rapid support response, request quotes from alternative providers. Most discover that total value comparison (not just monthly cost) reveals clear winners once business requirements are factored in.
