Business VoIP costs in the UK typically range from around £8 to £30+ per user per month , depending on the provider, features, call bundle, contract length, support level and whether you choose hosted VoIP, Microsoft Teams Phone, SIP trunking, UCaaS or contact centre software.
Most small UK businesses pay around £10 to £25 per user per month for a hosted VoIP or cloud phone system.
Microsoft Teams Phone can be cost-effective for businesses already using Microsoft 365, but external calling, call queues, Direct Routing, Operator Connect and compliance features can increase the total cost.
SIP trunking is often cheaper per channel, usually around £3 to £10 per channel per month , but it works best for businesses with an existing PBX, predictable call volumes or technical support.
Contact centre VoIP usually costs more, often £40 to £100+ per agent per month , because it includes features such as call queues, call recording, analytics, wallboards, routing, quality monitoring and CRM integration.

PSTN switch-off and VoIP migration costs The UK’s old PSTN landline network is being switched off by January 2027, which means businesses using traditional landlines, ISDN, fax lines, alarm lines, lift lines, payment terminals or other PSTN-reliant services need to check what must be upgraded.
VoIP migration costs can often include:
new VoIP service
number porting
broadband upgrade
router upgrade
new handsets
adapter for some legacy devices
testing alarms or payment lines
failover or backup connection
power backup
staff training
If your business still uses PSTN or ISDN, compare VoIP options early rather than waiting until your provider forces a migration.
When to compare VoIP quotes You should compare VoIP quotes if:
you still use traditional landlines
you still use ISDN
your contract is ending
call quality is poor
your phone bill has increased
you have moved to hybrid working
you need call recording
you need Microsoft Teams Phone
you need SIP trunks
you need multiple sites connected
you want better call reporting
you want to reduce support costs
you are planning for the PSTN switch-off
you want to replace an old PBX
you are adding new staff or offices
Compare VoIP quotes before renewing your phone contract or migrating from old landlines.
