Best Phone and Broadband Deals for Business: 2025 Guide

How Business Phone and Broadband Has Changed

The landscape for business communications packages changed significantly with the completion of the ISDN switch-off in December 2025. Businesses can no longer order traditional ISDN or PSTN phone lines from any UK provider. All new business phone provision is now VoIP-based — delivered over an internet connection.

This shift has created a cleaner market. Rather than separate copper phone lines and broadband, businesses now need one reliable internet connection and a VoIP-based telephony service sitting on top of it. Providers have responded with various bundle structures, though the economics of bundling versus buying separately are worth evaluating carefully.

What to Look for in a Business Phone and Broadband Deal

A genuinely good business communications deal should deliver:

• Fast, reliable broadband: FTTP (full fibre) is the right baseline for any business running VoIP, with at least 100Mbps recommended
• Business SLA: Fault repair within hours, not days — VoIP call quality depends on broadband availability
• Full VoIP feature set: Hunt groups, auto-attendant, voicemail-to-email, call recording, mobile app for remote workers
• Number portability: Ability to bring existing business numbers to the new system
• Per-user pricing: Telephony costs that scale with headcount rather than fixed capacity

Leading Business Phone and Broadband Bundle Options

BT Business (Broadband + BT Cloud Voice)

BT offers combined FTTC/FTTP broadband with BT Cloud Voice, their hosted VoIP platform. BT's bundle is competitively priced for the brand but premium compared to specialist VoIP providers. BT Cloud Voice delivers standard business VoIP features. Pricing starts from approximately £45/month for a small office with one broadband and 2-3 VoIP users.

Virgin Media Business (Broadband + Phone)

Virgin's bundled packages combine their cable/fibre broadband with a VoIP-based phone line. The independent network is a genuine advantage where available. Phone features on Virgin's standard bundle are more basic than dedicated VoIP platforms — suitable for businesses with simple telephony requirements. Pricing from approximately £45-£70/month depending on speed tier.

TalkTalk Business

TalkTalk Business offers broadband and hosted voice bundles targeting SMEs on cost. Pricing is competitive but support quality has historically been mixed. Suitable for cost-sensitive businesses with straightforward requirements.

AMVIA: Separate Best-of-Breed (Recommended Approach)

Rather than a pre-packaged bundle from a single provider, AMVIA's approach is to source the best available broadband for your address from any carrier — and pair it with a full-featured hosted VoIP system. This typically delivers:

• Better broadband pricing than any single provider's bundle
• A more capable VoIP system with more features than bundled phone lines
• Independent SLAs for broadband and telephony
• Full flexibility to change either component independently at contract renewal

Pricing Benchmarks

For a small business of 5-10 staff:

• Business FTTP 100-300Mbps: £40-£70/month
• Hosted VoIP for 5 users (including full feature set): £35-£75/month
• Combined total: approximately £75-£145/month

This compares favourably to the pre-ISDN-switch-off landscape where businesses were often paying similar amounts for FTTC broadband plus ISDN lines with fewer features and no remote working capability.

Teams Calling as an Alternative

For businesses already paying for Microsoft 365 Business or E-series licences, Microsoft Teams Calling adds PSTN capability directly within Teams. Monthly per-user costs are typically £7-£15 for the Teams Phone add-on. If your team already uses Teams for meetings and messaging, this is the most integrated approach and often the best value for the telephony component.
