The honest comparison for London businesses.
Both work. Different operational profiles. Most London SMEs in 2026 choose cloud PBX; specific scenarios still justify on-premise.
Cloud PBX (recommended for most London SMEs)
- Upfront cost: low — just setup + optional handsets
- Monthly cost: per-user predictable
- Maintenance: managed by provider, no on-site engineer
- Scaling: add/remove users in minutes via web admin
- Upgrades: automatic, no end-of-life cliff
- Failure mode: depends on internet; cellular failover available
- Best for: 95%+ of London SMEs, multi-site businesses, anyone who hates server rooms
On-premise PBX (specific use cases only)
- Upfront cost: high — PBX server typically £8,000-50,000+
- Monthly cost: SIP trunk lines + maintenance contract
- Maintenance: requires on-site engineer or maintenance contract
- Scaling: hardware-dependent, engineer-visit changes
- Upgrades: every 5-7 years, painful, often forced by end-of-life
- Failure mode: works during internet outages, fails if PBX hardware fails
- Best for: regulated industries, very large user counts (500+), legacy investment protection
Cloud PBX delivered across London.
Cloud PBX is internet-delivered — works anywhere with business broadband. Most London businesses have multiple FTTP options, which means cloud PBX works reliably citywide.
City of London (EC1-EC4)
Financial services density, regulated industries, leased-line frequency above UK average. SLAs matter more than headline pricing.
Canary Wharf (E14)

Shoreditch / Tech City (EC2/N1)
Creative, tech, media businesses. Heavy cloud-app usage. Multiple alt-net options including CityFibre and Community Fibre.
West End (W1, WC1, WC2)
Mixed retail, hospitality, professional services. Building stock varies — some postcodes excellent FTTP, others older buildings face install complexity.
King's Cross / Euston (N1/WC1)
Tech and consultancy concentration. Strong fibre infrastructure, multiple carriers. Common managed-office tenants.
South Bank / London Bridge (SE1)
Mixed corporate and hospitality. Newer infrastructure dominates. Strong leased-line availability.

Frequently asked questions
What is cloud PBX?
Cloud PBX (also called hosted PBX) puts your phone system's central routing — handling extensions, transfers, IVR menus, voicemail — in the cloud rather than on a physical server in your London office. From your team's perspective it works the same; the difference is no on-site hardware to maintain. Standard 2026 UK business phone system architecture.
How much does cloud PBX cost for London businesses?
Typical 2026 UK cloud PBX pricing: £8-25/user/month for the platform itself. Telexico starts at £12/user/month all-inclusive — hosted PBX, mobile + desktop apps, basic call recording, web admin, UK support. Add-ons: AI Receptionist £150+/month, Microsoft Teams integration +£3-8/user, advanced analytics +£4-8/user. Hardware (handsets) optional, £80-200 per phone if wanted.
What's the difference between cloud PBX and traditional PBX?
Traditional PBX is an on-site server (physical box in your London office) handling all call routing. Cloud PBX moves that function to the cloud. Cost differences: traditional PBX needs £8,000-50,000+ upfront for hardware, plus 5-7 year replacement cycle. Cloud PBX is per-user monthly, no upfront hardware. Most London SMEs in 2026 choose cloud PBX.
Do I need handsets for cloud PBX in London?
Optional. Modern cloud PBX delivers calls via desktop apps (Windows, Mac), mobile apps (iOS, Android), and optional desk handsets. Many London SMEs in 2026 skip handsets entirely — restaurants, retail, mobile field teams especially. If you want them: £80-200 per standard handset, £300-500 per premium with colour screen and key expansion.
Will cloud PBX work if my London internet goes down?
Cloud PBX depends on internet — same as cloud apps, email, card payments. If broadband fails, you lose phones unless failover is configured. Two options: (1) Mobile-app failover — calls route to staff mobiles via 4G/5G when broadband drops. Built-in, no extra cost. (2) 4G/5G failover on your office router — keeps office online (and cloud PBX working) during outages. Standard Telexico setup for businesses that genuinely can't afford phone outages.
Can I keep my London numbers when switching to cloud PBX?
Yes. UK number portability is statutory — any London 020 (or other) number can be ported to Telexico in 5-15 working days. The porting process: parallel setup, test, scheduled cutover. Zero downtime.
Is cloud PBX secure?
Yes, when properly configured. Cloud PBX uses encrypted SIP for call signalling and SRTP for voice content. Admin access multi-factor authenticated. Call recordings encrypted at rest. Real security risks (toll fraud from weak passwords, phishing) are handled via strong defaults and rate-limiting. Properly configured cloud PBX is typically more secure than legacy on-premise PBX that often had years of unpatched vulnerabilities.
