Zen VoIP Review 2026: Business Phone Costs, Features & Call Quality
Quick Answer
Zen VoIP is a UK business phone solution best suited to SMEs that want reliable call quality, clear pricing and strong customer support rather than the cheapest possible VoIP deal.
Zen offers business voice services through Zen Digital Voice and more advanced communications options such as CloudComms, making it a good fit for businesses moving away from traditional landlines before the UK PSTN switch-off.
Zen’s business Digital Voice pricing currently starts from £6.25 per month ex VAT for 1,000 minutes to UK landlines and mobiles, with an unlimited UK calls option from £12.50 per month ex VAT.
However, Zen may not be the best choice if you need advanced call centre tools, deep PBX customisation or a large multi-site VoIP rollout.

We think that Zen Business VoIP is a strong choice for SMEs looking to transition to digital voice services ahead of the PSTN switch-off because they offer affordable packages with all the essential features businesses need.
However, we do think that businesses in areas with less reliable internet may face challenges with call quality, and larger enterprises with complex telecom requirements should look to explore more advanced options.
