12 best business VoIP providers in the UK 2024 – Compared and reviewed

In the rapidly advancing world of technology, Voice over Internet Protocol (VoIP) has become a cornerstone for business communications. Offering a blend of versatility, efficiency, and cost-effectiveness, VoIP solutions are increasingly favoured by businesses across the UK. To aid in your selection, we have compared and reviewed the top 12 business VoIP providers in the UK for 2024.

What is VoIP?

VoIP, or Voice over Internet Protocol, is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.

Some VoIP services may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number – including local, long-distance, mobile, and international numbers.

Using VoIP can potentially reduce costs associated with traditional phone services and increase functionality by integrating with other services and software.

It is a key component in modern business communications infrastructure, offering flexibility and a host of advanced features.
