Business broadband Cardiff. Wales' business capital, properly engineered.
FTTP, leased lines, 4G/5G failover for Cardiff businesses across every CF postcode. Multiple carriers, one Telexico relationship. No CPI+3.9% mid-contract rises. UK engineer support — direct line, not call centre.
Fibre to the building, managed to the desk.
Full fibre (FTTP) runs fibre all the way into your premises over the Openreach or CityFibre network. Telexico supplies the managed router, checks what each carrier can deliver at your postcode and keeps it monitored.
Need the same speed up as down, guaranteed? That is a dedicated leased line, on the next page of the range.
Business broadband in Cardiff: the local picture
Cardiff, the Welsh capital, combines a strong media sector (anchored by BBC Cymru Wales), financial and professional services and a growing creative and tech base around Cardiff Bay. Connectivity expectations are high, so we check full-fibre and leased-line availability at your exact Cardiff address across Openreach, CityFibre and the alternative networks.
The honest 2026 picture for Cardiff business broadband.
Cardiff has good central fibre coverage — Openreach FTTP widely available in CF10, CF11 and adjacent districts, with continued rollout. Outer areas (CF3, CF14 outer, CF5 outer) have variable coverage and benefit from a site survey before commitment.
Typical options at a 2026 Cardiff business postcode:
- Openreach FTTP — widely available across Cardiff. 100Mbps-1Gbps symmetric typically, £45-120/month business plans.
- CityFibre FTTP — expanding coverage. Often 25-35% cheaper than Openreach equivalents where available.
- Virgin Media Business — coverage strong in inner Cardiff, mixed in outer areas.
- Leased lines — BT Openreach EAD/EoFTTC, Virgin Business. £300-2,000/month depending on bandwidth and SLA.
- 4G/5G failover or Starlink — for sites where fixed-line options are limited or for genuine network-independent backup.
We're vendor-agnostic. We check what's available at your specific postcode, quote across multiple carriers, and recommend what genuinely works for your operation — not what gets us the highest margin reselling.

Configured for Cardiff business reality.
Different Cardiff districts have different business broadband needs — building stock, fibre availability, sector concentration. Our recommendations reflect what works at your specific postcode.
City Centre (CF10)
Financial services, corporate headquarters, government and professional services density. Strong fibre infrastructure, multiple carriers, standard 7-14 day installs.
Cathays / Roath (CF24)
University-adjacent professional services, plus established office and retail businesses. Good fibre coverage.
Cardiff Bay (CF10, CF11)
Mix of corporate (Welsh Government, BBC Wales) and creative businesses. Strong fibre infrastructure.
Heath / Llanedeyrn (CF14, CF23)
Mix of healthcare, professional services, and SME concentration. Coverage strong on main routes.
Pontprennau / Pentwyn (CF23)
Established business park, light industrial concentration. Good infrastructure for industrial-grade connectivity.
Outer Cardiff (CF3, CF5, CF15)
Variable coverage depending on specific postcode — some areas have excellent FTTP, others still primarily FTTC. Site survey recommended.
How we work with Cardiff businesses.
We're a Wolverhampton-headquartered UK telecom company (64 Chapel Ash WV3 0TT). For physical broadband and leased line installs in Cardiff, we work through our national install partner network — typically the same engineers Openreach, CityFibre, or your other carrier would send for any UK provider.
What that means in practice for a Cardiff business:
- Physical broadband install — handled by your local Openreach/CityFibre/alt-net engineer. Install experience is identical to what BT or Virgin would deliver.
- Site survey — done remotely from Wolverhampton using carrier availability data, or via partner if you need an on-site visit.
- VoIP / hosted PBX / AI Receptionist — cloud-delivered, works the same whether you're in Cardiff or anywhere else in the UK.
- Business mobile — UK-wide SIM-based product, works across all UK networks.
- Ongoing support — single named UK engineer for your account, direct line to Telexico (not to BT/Openreach's tier-1 call centre).
The difference vs going direct to BT/Virgin: better contract terms, better pricing, better support relationship, and consolidation under one supplier.
What we don't promise: faster physical install than the carrier delivers. If Openreach takes 14 days to install FTTP at your building, it takes 14 days for everyone. We're honest about that.
What businesses gain by switching to Telexico.
How we differ from the big providers — written plainly, no sales spin.
Send us your current renewal. We'll review what you have, what you pay, and where we can simplify — no fixed-package pressure, no obligation.
What you actually get from Telexico.
Honest about scope. No aggressive sales tactics, no surprise renewal jumps, no tier-1 call-centre triage. Real UK engineers, transparent pricing, one provider relationship across the stack.
UK-based provider
Wolverhampton-headquartered. Engineers cover the West Midlands daily; UK-wide install via our partner network. Real UK engineer support, UK data residency, UK contractual relationship — not US-routed SaaS.
Real engineer support
When you call Telexico, you reach someone who can actually fix things. Response SLA backed by real engineering capacity rather than call-centre headcount. Named account manager for ongoing customers.
Free infrastructure review
Every engagement starts with a no-obligation audit of your current setup. Honest recommendation — sometimes that's "stay with your current provider after negotiation." We'd rather be honest than oversell.
Transparent pricing
What you sign for is what you pay — including renewal. No teaser pricing that jumps 30-100% at year two. No mid-contract CPI shock. Predictable multi-year cost from day one.
One provider, one platform
Broadband, hosted VoIP, business WiFi, AI Receptionist, 4G/5G failover, CCTV consolidated onto one Telexico relationship. Single bill, single support number, single engineer when something needs attention.
Migration project-managed
Switching to Telexico isn't DIY. We handle contract audit, notice timing, ordering, parallel running, cutover, old-provider close-out. Customer-visible disruption typically measured in minutes.

For businesses still on ISDN or aging on-premises PBX — an honest cost-and-feature comparison before the 2027 BT switch-off forces a rushed decision.
No hard sell. No fixed package pressure. If we're not a better fit, we'll tell you straight — and recommend what is.
Business broadband in Cardiff: the options, plainly.
Business broadband, business internet and full fibre in Cardiff are different names for a decision about speed, resilience and support. Here is what each option gives you and who it suits.
Full fibre broadband in Cardiff
Fibre to the premises, with symmetrical options where the network supports them. Where Openreach or CityFibre have built in Cardiff this is the default we quote; we check your exact postcode rather than the street.
Business broadband and SoGEA in Cardiff
Where full fibre has not reached yet, SoGEA and FTTC business lines with a static IP and business support hours keep you working until fibre arrives, with the upgrade path already planned.
Business internet with SLAs in Cardiff
Static IP addresses, a managed router with voice prioritisation and a defined fix time. For card machines, cloud software and phones that cannot afford a consumer-grade line.
Backup and failover
A 4G or 5G backup connection that takes over automatically when the primary line fails, so tills, phones and bookings in Cardiff keep running while the fault is fixed.
When broadband is not enough
Growing teams, heavy cloud use or several sites usually mean a leased line: dedicated, uncontended bandwidth with a service level agreement. We will tell you plainly which side of that line your business sits.
Fibre that stays up.
Frequently asked questions
Do you deliver business broadband across all of Cardiff?
Yes — across all CF postcodes (CF10, CF11, CF14, CF15, CF23, CF24, CF3, CF5) and surrounding areas. Cardiff has good central fibre coverage — Openreach FTTP widely available in CF10, CF11 and adjacent districts, with continued rollout. We're not Cardiff-based (our HQ is in Wolverhampton) but we deliver to Cardiff businesses through our national install network, with the same UK-engineer support model and no mid-contract price rises.
How does Telexico work for a Cardiff business when you're not Cardiff-based?
Honest answer: connectivity products (FTTP, leased lines, business mobile) are delivered through our national install partner network — typically the same engineers Openreach or CityFibre would send for any UK provider. The difference is the service wrapper: contract terms (no CPI+3.9% rises), pricing (typically 25-40% lower than BT/Virgin), support model (single named UK engineer for your account), and consolidation (broadband + VoIP + AI under one supplier). VoIP, AI Receptionist, and business mobile are cloud-delivered — they work the same whether you're in Cardiff or anywhere else in the UK.
What broadband options are available for Cardiff businesses in 2026?
Typical Cardiff options: (1) Openreach FTTP at 100Mbps-1Gbps symmetric — typically £45-120/month business plans. (2) CityFibre FTTP in expanding areas — often 25-35% cheaper than Openreach equivalents. (3) Virgin Media Business in selected areas. (4) Leased lines (BT Openreach, Virgin Business, alt-net providers) — £300-2,000/month depending on bandwidth and SLA. (5) 4G/5G failover or Starlink as primary connectivity at sites where fixed-line options are limited. We're vendor-agnostic and quote across carriers.
How long does business broadband install take in Cardiff?
Typical FTTP install: 5-14 working days where Openreach or alt-net fibre is already in your building. New fibre runs in older commercial buildings: 21-45 working days. Leased lines: 30-60 days typical. The bottleneck is the physical install which is the same regardless of provider. We give realistic timelines in the proposal, not optimistic best-case scenarios.
Can you deliver leased lines in Cardiff?
Yes. Leased lines in Cardiff are typically delivered via BT Openreach (EAD or EoFTTC) or Virgin Media Business. We work with multiple carriers and pick the best fit for your operational requirements. Typical pricing £300-800/month for 100Mbps symmetric, £600-1,500 for 1Gbps. Install timeline 30-60 days for standard urban deployments.
Does the 2027 PSTN switch-off affect Cardiff?
Yes — UK-wide. BT/Openreach is switching off the old PSTN/ISDN copper network in January 2027. Every UK business currently on PSTN/ISDN must migrate before then. Migration from PSTN/ISDN to a modern business phone system is what we do every week. Sooner is better than later — UK telecom installers will get progressively busier as 2027 approaches.
What about Telexico's pricing vs BT and Virgin in Cardiff?
For typical UK SMEs, Telexico is typically 25-40% cheaper than BT Business or Virgin Media Business at equivalent feature sets, primarily because: (1) no CPI+3.9% mid-contract rises, (2) features bundled into base price rather than charged separately, (3) AI Receptionist available as add-on at £150/month, which neither BT nor Virgin offer natively. For very large enterprises (1000+ users) the majors win on procurement scale. For SMEs (5-200 users), the maths typically favours Telexico substantially.
