| Bundling your business broadband and phone reduces costs, simplifies billing, and gives you a single point of contact when things go wrong. In 2026, with BT's copper-to-digital switchover accelerating, now is an important time to review your business phone and broadband setup together. | ||||||||||||||||||||||||||||||
|
Our Verdict
The best business broadband and phone bundle depends on whether you prioritise fixed-line voice (BT Digital Voice), mobile integration (Vodafone Business), or VoIP flexibility (third-party providers like 8x8 or RingCentral). Most businesses switching in 2026 should move to VoIP-based phone systems — they are cheaper, more flexible, and future-proof.

The BT Digital Voice Switchover: What Businesses Need to Know | ||||||||||||||||||||||||||||||
| BT is replacing the UK's copper phone network with Digital Voice (VoIP) by 2027. For businesses, this means any existing analogue phone lines will be migrated to digital. Key impacts include: alarm systems and EPOS machines may need upgrading, fax machines will no longer work on digital lines, and any device relying on a traditional phone line signal will need review. | ||||||||||||||||||||||||||||||
| ⚠️ Important: If your business uses alarm systems, payment terminals, or any device connected to a traditional phone line, check compatibility before switching to Digital Voice. Your new provider should assist with this assessment. | ||||||||||||||||||||||||||||||

Frequently Asked QuestionsWhat is the best business broadband and phone deal in the UK? BT Business offers one of the most complete broadband and phone bundles, including Digital Voice (VoIP) and access to BT's Wi-Fi network. Vodafone Business is best for bundling broadband with mobile lines under one bill. What is Digital Voice and how does it affect my business? Digital Voice is BT's VoIP-based phone service replacing traditional copper landlines. BT plans to complete the UK's switchover to digital phone lines by 2027. New phone line deals from most providers are now Digital Voice/VoIP-based rather than traditional PSTN lines. Can I keep my existing business phone number when switching? Yes. UK business phone numbers are portable. When switching providers, request number portability — your new provider will manage the transfer. Expect the transfer to take 5–10 working days. Is VoIP reliable enough for business use? Yes. Modern VoIP systems are highly reliable and feature-rich. They require a stable broadband connection (minimum 1Mbps per concurrent call). Providers like BT and Vodafone include built-in resilience and 4G backup to maintain phone service during broadband outages. Are business phone and broadband bundles cheaper than buying separately? Usually yes. Bundling can save £5–£15/month compared to separate contracts. The bigger saving is often administrative — one provider, one bill, one point of contact for faults. | ||||||||||||||||||||||||||||||
