The fallout from the COVID pandemic has resulted in the majority of businesses adopting a hybrid approach to working, whilst others have ditched the office entirely to work from their homes, which comes with its own challenges (such as attending a group meeting to discuss the team’s next big project, only for your internet to cut out as you begin presenting).Business phone lines aren’t just necessary for your telephone system; they are also necessary for your internet connection. And if you’d like to invest in an internet-based phone system for your business, you’ll still need a phone line. While some providers offer digital or virtual landline numbers, specialist VoIP providers offer more sophisticated call management software packages.So there's a lot to consider when making a choice for your business – which is where we can help.

Phone line providers offer different amounts for different monthly costs, so it’s important to conduct a business phone line comparison before you commit to a contract.If you're looking to include internet, check available internet speeds, too. According to business.org, a small business will need at least a 75Mb internet connection if it's looking to do things like stream videos, file share and even take numerous point of sale transactions. Luckily, 90% of the UK has access to super-fast broadband. Phone line provider sorted? What about your office phone system? Office phone systems are integral to the smooth running of your business, check out our best office phone systems guide to learn more. Secondly, you’ll need to decide on whether you’re sticking with a traditional phone service or investing in a VoIP phone service. Similarly to mobile phone contracts, business phone line providers offer inclusive minutes and the option to add-on things like calls abroad.If you decide that VoIP is the best option for your business, make sure your business phone line speed supports web conferencing and server hosting. For small businesses with 30+ employees, take a look at packages that offer download speeds of 145Mb to 300Mb.Bear in mind that BT is going to start switching off the traditional telephone network in 2025, so VoIP is the best way to future-proof your business. There are also a whole host of benefits to choosing VoIP which you can read about on our What is VoIP page. Considering phone line provider service levels And finally, what about service levels?Terry Martin, CEO of Hertfordshire-based Telecoms Company Just2Connect says:“An important, but often overlooked factor to consider when selecting a provider for your phone line is what Service Maintenance Level is included in your line package. The Service Maintenance Level dictates how quickly a line fault can be fixed – there are 4 levels.Should you have a fault, Openreach can take up to 3 days to fix a line with Level 1 Maintenance, but will fix the fault within 6 hours for a line with Level 4 Maintenance. Typically, most providers only include Level 1 in their monthly charge. In some cases, this may be suitable, however if your line is connected to your alarm system, then you will likely require a more responsive Service Level”. Conclusion: Key TakeawaysWith many providers to choose from, it's important you thoroughly research each product before making any decisions.Think about how a specific product and its features will be beneficial to your business needs. Be sure to factor in pricing, as costs can soon add up.Consider your employees and the technology required for them to work as efficiently as possible.It is difficult to make a clear decision, particularly when several competitors offer similar products. Which is why we've created a custom-built comparison tool to help pair you with providers most suitable to the needs of your business. Simply fill out the form, and we will do the rest. FAQsWhat is a leased line? A leased line is a private line that can exist between two offices or an office and a data server. Because a leased line is private, it means the bandwidth can only be used by your business, which means you benefit from faster download speeds, upload speeds, and a more reliable connection. Businesses can use a leased line to connect to the internet, link servers, and carry phone calls.What’s the difference between fibre and ADSL?While fibre broadband is delivered through fibre optic cable, ADSL (Asymmetric Digital Subscriber Line, is delivered through the standard copper phone line. Fibre is faster and more reliable than ADSL, and is now the preferred choice for households and businesses despite being more expensive than ADSL.Generally, with ADSL the further away you live from the telephone exchange, the slower and less reliable your connection. However, with fibre, fibre-optic cable delivers data from the telephone exchange to a local cabinet. The data journey then finishes along a copper phone line from the cabinet to your premise, so it has less far to travel at a slower speed. What’s the difference between FTTC and FTTP?FTTC stands for Fibre to the Cabinet, while FTTP stands for Fibre to the Premises. FTTC means data is delivered from the telephone exchange to the local cabinet, where it then continues its journey along a standard copper line. FTTP means the fibre connection continues straight to your business premises from the exchange, which means you benefit from much faster download and upload speeds. What is VoIP?VoIP stands for Voice over Internet Protocol. It means that your voice data is turned into digital data and is sent over the internet, rather than the traditional telephone line. Because VoIP is a digital telephone service, businesses can invest in software that gives you greater control over your calls, including call recording, call forwarding, and the option to record an auto-attendant.What is a PBX?PBX stands for Private Branch Exchange. It’s a piece of technology that allows you to direct calls to a specific phone or department phone network. A PBX can either be cloud-based or on-premise. A cloud-based PBX manages your calls on an off-site server, while an on-premise PBX directs your calls once the call has reached your on-site server. What is a virtual phone number?A virtual number isn’t directly associated with a phone line. Instead, it’s a cloud-based number that acts as a getaway to a forwarding network. When a person calls the number, it forwards the call to a pre-set phone number, and from that point, uses either the digital or traditional phone line to manage the call. A virtual number enables a business to appear in a specific location. For example, a business can appear to have a London number. When a person calls the number, the call is then automatically forwarded to the business’ fixed number.You can find out more about the best virtual landlines and how they work on our dedicated virtual landlines page.
