Types of business phone lines explained
There are several types of business phone lines available, each with distinct features and pricing options. Whether you’re looking for the cheapest phone line for business or want to future-proof your setup, here’s what to know:
Traditional landline
Traditional business telephone lines run on PSTN or ISDN infrastructure. These systems are being permanently switched off by the end of 2027, meaning businesses still using them need to upgrade.
If your business currently uses a landline, it’s time to move to a digital or VoIP alternative.
VoIP (Voice over IP)
Business VoIP phone systems work over the internet and are now the most flexible and cost-effective way to run a business phone line. It’s cloud-based, meaning you can make and receive calls on mobiles, laptops, or IP handsets.
Most business phone line providers now recommend VoIP as standard.
Digital phone lines
Digital phone lines also work over the internet, but they’re designed to replicate a landline experience. Often bundled with broadband deals, they’re simple to set up using your existing connection and a digital-capable phone or adapter.
They’re ideal for small businesses or those looking for a direct upgrade from PSTN, without moving to a full VoIP system.
Benefits of a business phone line
In 2026, digital business phone lines will be the best choice for any company that has sufficient broadband speed. Here are the top five reasons businesses are choosing digital phone line solutions:
It's cheaper
Unlike traditional landline phones, a digital phone system does not require the maintenance of its own physical infrastructure. This results in lower monthly rates, no line rental fees, and cheaper international calls compared to traditional phone lines.
It's scalable
Digital phone lines are ideal for growing businesses. Adding new users does not require an engineer to physically install new cables. A business phone line package can flexibly adapt to the changing needs of your business.
It's versatile
A business phone line system is much more versatile, improving the way businesses communicate. It allows your business to seamlessly route calls between office handsets and external mobile devices.
Software integrations
Business phone lines can easily integrate with project management, CRM, or other digital workplace solutions that your business uses every day.
High-quality calls
Digital business phone lines use fibre optic cables to transmit call data at the speed of light using Voice over Internet Protocol technology. This modern technology offers superior call quality compared to traditional landlines. Find out more in our guide to VoIP call quality.
How to choose a business phone line provider
Not all business phone line providers offer the same level of service, so it’s worth taking a moment to check what’s included before you sign up. From support to value, here are three things to look out for:
Dedicated business support
Choose a provider that offers fast, reliable support for business customers. If issues come up, you’ll want a team that can resolve them quickly without disrupting your operations.
Real customer reviews
Check platforms like Trustpilot to see how current users rate the provider’s service. Look for consistently positive feedback on reliability, support, and ease of setup.
Bundled services
Many business phone line providers offer packages that also include broadband. Bundling can save money and make managing your services much simpler.

Business phone line costs
Business phone contracts can include a mix of one-off and monthly charges, depending on the setup and provider. Most plans include a monthly fee per user, which increases as more phone lines are added. VoIP systems often work with mobiles or desktop apps, but physical handsets are available at an extra cost if needed.
Some packages include unlimited UK call minutes, while others offer a set monthly allowance. If your team makes only occasional international calls, a pay-as-you-go model is usually more cost-effective than a bundled international plan.
Advanced features like call recording, call routing, and voicemail-to-email are typically reserved for higher-tier packages, which come at an extra monthly price. Many providers also offer enhanced support, such as guaranteed response times, through paid service-level agreements (SLAs).
Line rental may still apply if your business phone runs over a part-fibre (SoGEA broadband) or legacy PSTN/ISDN connection. However, it’s not needed for VoIP-only service. Typical monthly line rental costs range from £11 to £20, depending on the line type.
Phone lines for small businesses
In the digital age, small companies require reliable, flexible communication solutions that adapt to dynamic business needs.
VoIP phone systems for small businesses offer seamless integration with cloud-based software solutions and the flexibility to be used anywhere.
Here, we’ll address some of the key aspects of phone lines for small businesses.
Services for small number of users
The cost of a business phone line scales with the number of users. In a typical business phone line contract, there is a fixed monthly license fee per user, making it affordable for small companies.
It’s also possible to sign up for a small business phone line package with only a limited number of monthly inclusive minutes. This is ideal for small businesses that use their phone line occasionally.

Broadband requirements for business phone lines
Modern business phone lines depend on a fast, reliable broadband connection. When reviewing business broadband deals, it’s worth considering a package that includes your phone line.
Below are some key points to keep in mind when combining a phone line with your broadband service.
What kind of broadband do you need?
To support digital or VoIP phone lines, your broadband must be fast and stable. Options like full fibre business broadband and leased line broadband offer the reliability needed for clear calls and multiple users.
What happens if broadband goes down?
If your broadband fails, your digital phone line will stop working. To prevent disruptions, businesses typically use a business broadband failover solution. This is either having a backup connection, or having a 4G enabled business broadband router to provide redundancy in the case of a problem with your broadband.
What are your speed requirements?
Broadband speed plays a key role in call quality. Each simultanous digital phone call needs around 3 Mbps of upload and download, plus low latency (under 150ms) for smooth, real-time conversations. Network load balancing can be used to prioritise VoIP traffic to ensure these minimum requirements are met.
What to expect with a business phone line?
The terminology around business phone lines is often confusing, making it difficult to understand what a business phone line system will deliver.
Our experts have summarised below the three most important aspects of a digital business phone line. If you want a more in-depth explanation, visit our guide to understanding VoIP phone lines.
Reliablity
Digital phone lines rely on the fibre optics technology in business broadband connections. Modern fibre technology is much more reliable than the copper infrastructure used in older landline systems.
Call management
Cloud-based business phone line systems centralise phone system management with digital voicemails, multiple phone line call routing, and transfers, eliminating the costs associated with physical phone systems.
Remote access
Digital phone calls can be securely routed to any device, including mobile phones. A business phone line will enable excellent communication across your business, even if your employees work across the globe. Find out more in our guide to remote office phone systems.
The analogue phone line switch off
The system of copper cables spanning Britain has served the country well for over a hundred years, providing reliable infrastructure for phone lines.
However, with gradual improvements in broadband technology, the phone network is no longer the most efficient or cost-effective way to send and receive phone calls.
The landline phone system is being gradually phased out as Openreach lays its full fibre network across the country. Where full fibre is available, businesses will not be able to sign up for an analogue phone line.

Business phone line – FAQs
Our in-house commercial telecom experts answer key questions asked by business owners choosing their next phone system.
Is there a business line rental charge?
There is no line rental charge for digital business phone lines.
Line rental applies to traditional landline phones, covering the cost of maintaining copper cables that connect your premises to the phone network, such as Openreach or KCOM.
Digital phone lines work over broadband connections and do not use the old copper network, so no separate line rental charge applies.
Do you still need line rental with VoIP?
Not always. You don’t need line rental if your VoIP system runs over a full fibre connection or leased line, as these use data-only networks. However, if your VoIP setup uses part-fibre, broadband like SoGEA line rental may still apply because the connection relies on a copper phone line.
The need for line rental depends on how your broadband is delivered, not the VoIP service itself.
When switching business phone line providers, can I keep the same number?
Yes, you can keep your business phone numbers in a process called ‘porting’. This is a standard procedure that is carefully regulated by Ofcom.
Depending on your existing business phone line setup, our telecoms experts will be on hand to advise on the process of porting your existing phone numbers to your new contract.
What’s the difference between a business phone line and a home landline?
Home and business digital phone lines use the same technology to make and receive calls reliably.
However, there are a few key details to be aware of when comparing business and home phone line packages:
- Price – Business phone line packages are typically larger contracts with many separate phone devices and numbers, making them more expensive than an individual phone used at home.
- Repair times – Business phone line providers recognise that the reliability of a phone system is critical for businesses. Business phone line contracts usually include a guaranteed fault repair time.
- Additional features – Business phone line contracts often include useful business features such as three-way calling.
What is the cheapest business phone line?
The cheapest business phone lines are usually digital or VoIP-based, especially when bundled with broadband. Prices vary by provider, features, and contract length, but digital phone lines typically offer the best value.
