Business Connectivity & Cloud Communications for Cardiff & South Wales
Leased lines, business broadband, cloud services, and VoIP phone systems for businesses across Cardiff and South Wales. Fast, reliable, and built to scale.
Your business deserves fast, reliable, and secure connectivity, and that's exactly what we deliver across Cardiff, Newport, Bridgend, Swansea, and the wider South Wales region. From dedicated leased lines to ultrafast broadband, cloud phone solutions, and Microsoft Teams Phone systems, we keep organisations connected and performing at their best.
Whether you're a growing SME or a multi-site organisation, our solutions are built to support cloud applications, hybrid working, VoIP, video conferencing, and mission-critical operations. And if you'd like your business phone and broadband from the same supplier, we can provide, install and support both, alongside your IT.
Wondering whether it's worth having your connectivity, phones and IT support with one provider? We've written about why the finger pointing stops when one supplier is accountable for all three.
Leased Lines in Cardiff & South Wales
A leased line gives your business a dedicated, uncontended internet connection with symmetrical upload and download speeds, ideal for cloud services, VoIP, Teams calls, and high-volume data transfer.
Why businesses in South Wales choose our leased lines
- Dedicated 1:1 bandwidth, no sharing, no slowdowns
- Symmetrical speeds from 100 Mbps to 10 Gbps
- 99.99% uptime with enterprise-grade SLAs

Leased lines are perfect for businesses relying on cloud platforms, remote teams, large file transfers, or high-availability operations.
Business Broadband for Cardiff & South Wales
As one of the business broadband providers serving South Wales, we provide fast, stable, and secure broadband solutions for SMEs, retail, hospitality, education, and professional services across the region.
Broadband options available locally
- FTTP (Full Fibre): gigabit-capable speeds for modern digital workplaces
- SOGEA: data-only broadband without a phone line
- Enhanced security: optional firewalls, VPNs, and content filtering
Designed for SMEs and remote teams, our broadband keeps your business online with stable performance and UK-based support. If your business also needs strong in-building coverage, see our high-performance Wi-Fi solutions.
Coverage varies by postcode, and we can check availability instantly.
If you're comparing small business broadband deals, or need commercial broadband for a busy office or several sites, we'll recommend the connection that genuinely fits, not simply the fastest or most expensive one. Fast, dependable connectivity is also what makes the cloud work well; our cloud services and Microsoft 365 pages cover that side.
Business Phone and Broadband from One Supplier
Your phones run over your internet connection, so it makes sense to have one supplier responsible for both. We offer two business phone systems:
CCSW CallOne

The UK's traditional phone network switches off on 31 January 2027. If you're still on old phone lines, our guide to the PSTN switch-off explains what to do.
