What speed your office actually needs.
Most offices over-buy on speed and under-buy on upload, failover and WiFi quality. Here's what the honest sizing looks like.
Small office (1-10 staff)
Recommended: 100-300Mbps FTTP business broadband with 4G/5G failover.
Typical cost: £40-60/month internet + £20-30/month failover. £700-1,100 first-year total.
Why: handles email, cloud apps, 5-8 concurrent video calls, light cloud backup. Failover keeps card payments and VoIP live during outages.
Medium office (10-30 staff)
Recommended: 500Mbps-1Gbps FTTP with managed router, QoS, 4G/5G failover.
Typical cost: £60-90/month internet + £30-40/month failover. £1,000-1,500 first-year total.
Why: supports 15-25 concurrent video meetings, cloud-heavy productivity, VoIP at scale, daily cloud backup uploads.
Larger office (30-100 staff)
Recommended: 1Gbps FTTP with engineering review, OR 100-300Mbps leased line if uptime is critical. Always with failover.
Typical cost FTTP route: £70-90/month + failover. Leased line route: £250-500/month.
Why: at this scale upload speeds matter more than download; leased line's symmetric upload often justifies the cost vs asymmetric FTTP.
The thing most offices get wrong: they buy gigabit FTTP because it's the headline speed available, but on an asymmetric package the upload is only 100-200Mbps. When 25 people are on simultaneous Teams calls (each call uses 2-4Mbps upload), the upload saturates and call quality degrades for everyone. The honest sizing isn't "biggest available download" — it's "enough upload for your worst-case concurrent usage". For offices with heavy video meeting load, this often points toward symmetric services (leased line or symmetric FTTP) rather than the highest-spec asymmetric product.
Which is right for your office?
FTTP business broadband
Choose this when:
- 1-50 staff, single-site office
- Standard hybrid working, cloud apps, video meetings
- Downtime tolerance: 4-8 hours is uncomfortable but survivable
- Budget pressure on monthly cost
- FTTP available at postcode
Typical cost: £40-90/month + failover. Full fibre details →
Leased line
Choose this when:
- 50+ staff, multi-site, or mission-critical operations
- Contractual or regulatory uptime requirements
- Symmetric upload needs (video broadcast, design studios, backup-heavy)
- Downtime cost is measurable (e.g. card payment outage → trade stops)
- Need for SLA-backed restoration windows
Typical cost: £250-£500/month for 100Mbps. Leased line cost details →
Internet is one component. Five things complete the office setup.
Properly-designed WiFi
Office WiFi is not "put the router in the corner and hope". Site survey, AP placement engineered around the building, central management, PCI-compliant guest network, fast roaming. Typical £400-1500/AP plus management.
Read more →4G/5G failover
Recommended as standard with any office internet. Keeps card payments, VoIP and cloud apps working when primary internet drops. Typical £20-40/month. Automatic, tested quarterly.
Read more →Hosted VoIP
Office phones now run over the same internet. Hosted VoIP with QoS designed in. Mobile apps for hybrid working. AI Receptionist option for after-hours.
Read more →Microsoft Teams Phone
For Microsoft 365 offices — voice integrated into Teams. Calls, voicemail, meetings all in one app. Direct Routing or Operator Connect deployment.
Read more →Multi-site management
Multiple office locations? SD-WAN ties them together as one private network. Central management, intelligent routing, consistent network experience across every site.
Read more →CCTV & security
Hikvision business CCTV designed alongside the network. PoE-powered cameras share the office network infrastructure. Cloud backup over the same internet.
Read more →Buy the office stack as one system, not five suppliers.
Most UK offices end up with their internet, phones, WiFi, failover and CCTV all from different suppliers. The result: five contracts, five support relationships, five renewal dates, and finger-pointing when something goes wrong across the boundary between two suppliers.
Telexico designs the office stack as one system. The business internet supports VoIP traffic with QoS configured for voice. The WiFi runs on a network designed around the actual building, not the broadband box. The failover preserves in-progress calls during a cutover. The CCTV runs on its own VLAN segregated from staff devices. One support team owns the whole stack — when something needs attention, one phone call resolves it.
The free Telexico audit looks at your current office setup and tells you honestly where consolidation makes sense and where it doesn't. We are a UK business connectivity and communications provider — engineering-led, plain contracts, no mid-contract price rises, UK-based support team. Suitable for typical UK offices of 5-200 staff.

Frequently asked questions
What internet speed does an office actually need?
Depends on user count and what staff are doing. Rough sizing: small office (1-10 staff doing email, cloud apps, light video calls) — 100Mbps download / 50Mbps upload typically sufficient. Medium office (10-30 staff with regular video meetings, cloud-heavy work) — 300Mbps+ down / 100Mbps+ up recommended. Larger office (30-100 staff with multiple concurrent video conferences, CCTV uploads, cloud backups) — 500Mbps-1Gbps symmetric ideal. The single biggest factor is concurrent video meetings: each video call uses 2-4Mbps and the upload tends to be the bottleneck. If 30 people are on simultaneous video calls, you need 120-150Mbps upload available, which means leased line or high-tier FTTP territory.
How much does business internet for an office cost?
For typical UK offices, ranges: FTTC business broadband (up to 80/20Mbps): £30-50/month. FTTP business broadband at 300-500Mbps: £40-60/month. FTTP gigabit business broadband: £55-90/month. Dedicated leased line at 100Mbps symmetric: £220-480/month. Multi-site office estates run higher overall but per-site costs follow these ranges. Add 4G/5G failover (recommended as standard): £20-40/month. Managed business WiFi: £15-30/access point/month if leased, or one-off purchase model also available.
Is consumer broadband okay for a small office?
Technically usable for a 1-3 person home-office-style setup, but not advisable for any business operation. Why: consumer broadband is engineered for residential use patterns (browsing, streaming) not business (sustained upload, VoIP, video conferencing). Business broadband provides: business-grade SLAs with restoration windows, business-hours technical support, symmetric or near-symmetric upload speeds, static IP options, traffic prioritisation suitable for VoIP. Consumer is cheaper but the cost of an outage during business hours, plus inability to host VoIP cleanly, plus lack of business support, makes the saving questionable. For any office with more than 2 staff or running VoIP, business broadband is the correct choice.
Does my office need a leased line or is broadband enough?
For most UK offices under 50 staff: high-tier full fibre business broadband (500Mbps-1Gbps) with proper 4G/5G failover is usually the right answer. Cost: £60-90/month plus £25/month failover. Reliability: very good, multiple-failover paths. For offices with 50+ staff, mission-critical cloud operations, multi-site networking, or contractual uptime requirements: leased line typically £250-£500/month becomes the right answer. The honest test: if 30 minutes of unplanned internet downtime would cause more than £200 of business impact, leased line economics start making sense. If the impact is lower, FTTP + failover is the better fit.
What does business internet need to support for hybrid working?
Hybrid working means: staff in the office on video calls with staff at home; cloud documents collaborated in real time; VPN access from home into office systems; secure remote access to internal applications. Internet requirements: stable upload speed for office-side video participants (multiple concurrent calls = multi-Mbps upload sustained); QoS configured to prioritise voice and video traffic; secure remote access infrastructure (typically VPN or zero-trust); reliable WiFi for staff who move between desks; and 4G/5G failover so the hybrid setup doesn't collapse during an outage. The whole office becomes 'an extension of the cloud' — bad internet means bad hybrid working.
Can I get business internet to my office quickly?
Depends on what infrastructure is already at your building. FTTP (full fibre) business broadband: typically 7-14 working days install if FTTP is already at your postcode. FTTC business broadband: typically 5-10 working days. Leased line: 60-120 working days (much longer because of carrier survey and possible civil engineering). 4G/5G business internet (for temporary or rapid-deploy): 1-2 days. Starlink business internet: 1-2 days. If you have a hard deadline (lease start date, business launch), order well before — telecom installs are the most common cause of business move-in delays.
What about WiFi for the office, is that included?
WiFi is a separate product from business internet. Business internet brings the connectivity into the building; WiFi distributes it within the building. Office WiFi options: small office (1-3 access points) can sometimes work from a single mesh system at £200-500 one-off. Most offices need properly-designed managed WiFi — multiple business-grade access points, central management, guest network isolation. Typical cost: £400-1500 per access point for hardware plus £15-30/AP/month if managed. Telexico designs WiFi alongside the business internet — proper site survey, AP placement engineered around the actual building rather than guessed, PCI-compliant guest network for visitor traffic separated from business traffic.
