The best virtual landlines for UK businesses can help your hybrid working setups flourish, support clear call quality, and even slash your phone bills by up to 70%.
Due to the PSTN (Public Switched Telephone Network) being officially phased out by December 2025, all UK businesses have to switch to a virtual telephone system. I’d advise switching to a virtual phone number soon. This will allow you to take advantage of the current competitive prices, while having ample time to train your staff on the new system, and avoid any possible delays from a mass migration.

What is a Virtual Phone Number, and Why Does My Business Need One?
A virtual phone number is not directly linked to a specific phone line or physical device. You simply open an account (which the virtual number will be registered to), and you can then forward calls to any other phone number or device. This lets you take calls from mobile phones, landlines, or VoIP (Voice over Internet Protocol) systems.
Switching to a virtual landline or VoIP system will soon be necessary due to the Big Switch Off in 2025, and many UK businesses are voluntarily making the switch due to the numerous benefits virtual phones offer.
Virtual landline systems allow flexibility in choosing your local, international, toll-free, or vanity number to project a professional image to your customer base. They also make upscaling your phone system easier, improve call quality, offer cost savings, and introduce advanced call management features.
How do virtual landlines work?
Virtual landlines are powered by VoIP technology, providing added flexibility because they operate over the internet.
When making or receiving calls, voice signals are sent in small data packets over the internet instead of traditional phone lines. This means there’s no need to purchase special hardware or undergo a lengthy installation process.
Additionally, adding further extensions does not require adding more phone lines. You simply need to register a new number with your virtual phone provider.
What is the difference between VoIP and virtual landline systems?
VoIP stands for Voice over Internet Protocol, the technology used to transmit voice signals over the Internet. Virtual landline systems use VoIP technology to offer a service that resembles traditional landlines but operates with different technology. While closely related, VoIP mainly refers to the technology rather than the end product.
Benefits of the Best UK Virtual Phone Systems
Aside from convenience and reliability, here are the key benefits of using the best UK virtual phone systems:
Virtual phone systems provide a cost-effective solution for users making frequent calls. These plans offer significant savings over traditional landline or cellphone services by eliminating costly roaming charges and international fees. Plus, there are no additional taxes or surcharges associated with VoIP services.
Virtual phone systems come in various packages to suit the needs of different customers. These plans can be tailored to include specific features such as call forwarding, voicemail, and caller ID.
With a virtual phone service, users can access their phone lines anywhere. This makes staying connected while travelling or working remotely easy without needing a fixed physical location. Plus, many virtual number providers offer mobile applications that allow customers to make and receive calls on their smartphones or tablets.
The best virtual phone systems provide crystal-clear sound quality for all types of conversations, whether local or international. Many providers offer additional features like noise cancellation and echo suppression for a pleasant calling experience.
Lastly, virtual phone systems have various call management features that make communication more accessible and efficient. For example, customers can store unlimited contacts in their address books, quickly access voicemail messages, and enjoy advanced call-handling features like call recording, forwarding, and Interactive Voice Response (IVR).
What features should a virtual landline service have?
When looking for a virtual landline service in the UK, there are a few key features to look out for to ensure you are selecting the right service for your needs.
First, you should determine your primary use case for the virtual landline. Are you mainly dealing with external customer calls or internal communication with colleagues? Within the former, do you typically deal with inbound calls (e.g., customer support agents, receptionists, small businesses) or outbound calls (e.g., sales reps, recruiters, fundraisers)?
Depending on your answers, you should look out for different features:
When looking for a phone system suitable for internal team communication, you might consider video conferencing, encryption, team messaging platforms, file sharing, mobile apps, and integrations with productivity or communication apps such as Slack or Microsoft Teams.
If you’ll be handling inbound external calls, you should look for features like call forwarding, auto-attendant, IVR, caller ID, blocking, queuing, recording, custom greetings, business hours setup, voicemail-to-email notifications, and call analytics.
For outbound external calls, additional important features include CRM integration, click-to-call auto-dialer, call scripts, voicemail drop, and AI assistants.
Are There Free Virtual Landline Providers for UK Businesses?
When it comes to entirely free VoIP services for businesses in the UK, free forever options do not exist.
Ooma’s Basic plan is free (minus hardware costs, taxes, and fees); however, it is designed for household use and is thus unsuitable for businesses. Most companies on our shortlist provide a free trial that offers full or partial access to their services for seven to 30 days. This allows you to test before you buy. The longest free trial services include 8×8, Dialpad, and RingCentral.
There are also some very affordable premium plans. For example, you can enjoy unlimited domestic calling with Vonage for just £18 per user, per month. Phone.com also offers an unlimited calling plan for £14.33 ($18.69 USD) per user, per month.
How We Chose the Best Virtual Phone Number Providers
With so many virtual phone number providers on the market, I extensively researched the options available to determine which are best. I took these factors into consideration:
I looked for providers that offer a wide range of features, including HD voice quality, call forwarding and voicemail, auto attendants, conference calling, and virtual numbers.
I considered the types of numbers available from each virtual phone number provider — both local and international — and any additional services such as toll-free or vanity numbers.
I considered the cost of plans to ensure that they’re competitively priced and provide excellent value for money, including scaling, to ensure your phone system can grow alongside your business.
Service reliability is essential when choosing a virtual phone number provider, so I looked for providers with high uptime guarantees to improve customer satisfaction and avoid frustration caused by call failure.
I evaluated each provider’s interface to ensure it was easy to use and offered intuitive features.
