Market-leading business phone systems, coupled with outstanding UK-based customer care. As one of the UK's most trusted VoIP providers, T2k Voice & Data helps companies move away from outdated fixed-line setups and onto reliable, scalable cloud telephony — backed by a telecoms team that's been doing this for over 35 years.
As an independent telecoms provider, we're not tied to a single network or manufacturer — we review the market constantly and only partner with the VoIP providers and hardware brands we'd recommend to our own team. Right now, there are three market-leading office phone system providers' platforms we put forward to clients, each suited to a different size and type of business. Click through below to compare, or get in touch if you'd like help choosing the right fit.
Virtual landline service for small companies looking for flexibility, cost reductions and a replacement for fixed-line services.
Horizon is a feature-rich hosted VoIP solution, suitable for businesses of all sizes and built on a UK-based network.
3CX is a highly flexible VoIP phone system is especially good for large businesses looking for a more tailored service.
A VoIP phone system is only as reliable as the connection behind it. Our business-only broadband and leased line services are built to keep call quality consistent, even during peak usage — because a telecoms provider that only sells you the handset isn't solving the whole problem.
High-speed, business-only broadband connections.

High-capacity, dedicated fibre connectivity.

For many companies, their internal network is as vital as their internet connection, which is why we offer a comprehensive network design and installation service. We work throughout the UK and have in the past travelled overseas for network installations. Our fully qualified and knowledgeable engineers work with you to provide the ideal data services and create a resilient and high-performance internal network.
For over 35 years, T2k has provided telecommunications services to UK businesses, and we've concentrated on staying ahead of the industry as it's changed. Today, with most telecoms companies moving customers off ISDN and PSTN ahead of BT's 2027 switch-off, we're helping both existing and new customers move onto VoIP — without the disruption a forced migration usually brings.
We work with hundreds of UK businesses and support thousands of users. We aim to provide tailored services that fulfil business needs while offering the highest customer care level. While we aren't the largest business phone system provider you'll come across, we think you'll appreciate the personal service our company offers. Many of our team have been with us for one or more decades, and as such, our business customers get continuity and account managers who are here for the long haul.
We choose to work with only the best business telecoms services and regularly review new technology as it comes to market to provide our customers with the latest telecommunications advice.
We regularly post guides about business telecoms; here is a selection of a few that we hope help to answer some of the questions you may have.



The starting point for all of our customers is an initial call and subsequent meeting. We want to understand your requirements and plans for the future, and then we can help you identify the best communications service for your company. We have knowledge of a range of solutions and other services and can quickly help you find the best services and the best deal.
