Cloud PBX London. No on-site PBX. No comms-cabinet drama.
Hosted PBX delivered as a cloud service for London businesses. No on-site hardware, no end-of-life upgrades, no server room. All features (call recording, IVR, hunt groups, analytics) included on standard tier. From £5/user/month.
How we work in London.
Hosted phone systems are delivered over your internet connection, so most of the install is configuration. Hosted systems are configured and supported from Wolverhampton; when hands-on work is needed, site visits are booked through our UK engineering partner network.
Where we install
the City, Canary Wharf, Shoreditch, King’s Cross, Westminster, Stratford and Croydon, and across the M25.
Connectivity underneath
Openreach full fibre plus London’s many alternative networks, and the densest choice of leased-line carriers in the country; we check your exact postcode before quoting.
Typical timings
Number porting takes one to three weeks from authorisation depending on the line type; new full-fibre lines usually arrive within a few weeks of order; a hosted phone system can be configured and shipped in days. Nothing switches until the new set-up is tested alongside the old one.
From £5 per user, per month.
No PBX hardware to buy and no big upfront cost — cloud phone systems that scale with your team. And because it’s all cloud-delivered, your platform can be activated the same day, with number porting typically completing in 5–14 working days.

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)
Modern building stock, dense fibre infrastructure, multiple carrier options. Strong 5G coverage. Consultancy and finance SME concentration.
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.

Every kind of business phone system in London, on one page.
Searches for cloud PBX, hosted VoIP, business VoIP, office and small-business phone systems in London all lead to the same modern set-up: calls carried over your internet connection, managed in the cloud, answered on a desk phone, a laptop or the Telexico Mobile App. Here is what each term means and when it fits.
Cloud PBX in London
The phone system itself lives in a UK data centre instead of a box on your wall. Nothing to maintain on site, new users added in minutes, and the same system follows you if you move premises in London.
Hosted VoIP and business VoIP in London
What most London businesses are really asking for: calls carried over your internet connection, with desk phones, desktop apps and the Telexico Mobile App on one business number, and queues, voicemail-to-email and call recording included. Quality depends on the broadband underneath, so we check the line before we quote the phones.
Small business phone systems in London
Two to twenty users: a welcome message, a ring group and the mobile app, priced per user per month, with most installs done without an engineer visit.
Office and multi-site phone systems in London
Larger teams and several sites: departments, IVR menus, wallboards, call recording for compliance and one directory across every location, so a London office and branches elsewhere run as one system.
SIP trunks in London
If you already own a PBX you like, SIP trunks replace the ISDN lines underneath it and cut the line rental. If you do not, a hosted system is usually simpler than keeping the old box alive.
Business telephone systems and the switch-off
Traditional telephone systems in London on analogue or ISDN lines need to move before the PSTN switch-off. We port your numbers, run the new system alongside the old one and cut over when you are ready.

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 £5/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. Minimal planned 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.
