BT Business Phone and Broadband: Plans & Pricing Guide

For small businesses looking to consolidate their internet and phone services under a single provider, BT Business phone and broadband bundles are among the most widely available options in the UK. They combine a business broadband connection with line rental and, in most cases, a calls package — delivered over either FTTC, FTTP or older ADSL technology depending on what is available at your premises.

What Does a BT Business Phone and Broadband Bundle Include?

The exact contents of BT Business bundles vary by product tier, but a typical package includes:

• A business broadband connection (FTTC or FTTP depending on availability)
• A business line rental (or WLR — Wholesale Line Rental — provided over the Openreach network)
• An inclusive calls allowance — usually unlimited UK landline calls and sometimes mobile calls
• A static IP address
• A BT SmartHub business router
• Technical support via BT Business

BT Business Bundle Pricing

Indicative pricing for BT Business phone and broadband bundles on 24-month contracts:

• Essential (FTTC up to 76Mbps + line + calls): £35–£50/month
• Fibre 150 (FTTP 150Mbps + line + calls): £45–£60/month
• Fibre 500 (FTTP 500Mbps + line + calls): £55–£70/month
• Fibre 900 (FTTP 900Mbps + line + calls): £65–£80/month

These are guide prices. BT regularly runs promotional offers that reduce the upfront or monthly cost, and negotiated pricing is often available for businesses taking multiple lines or managing their contract renewal proactively.

The Phone Component: Traditional Line vs VoIP

BT Business bundles have traditionally included a physical phone line (PSTN or ISDN). However, the UK telephony network is undergoing a significant transition. BT is retiring the PSTN and ISDN network by January 2027, meaning all voice services will move to IP-based (VoIP) delivery.

This transition affects how BT's phone bundles work. Newer BT Business packages deliver voice over Digital Voice (an IP-based service using the broadband connection), rather than over a separate copper phone line. For businesses still on traditional PSTN lines, this is an important consideration — and a good prompt to review whether a hosted VoIP system might be a more capable and cost-effective solution than a like-for-like replacement.

Is a Bundle the Right Approach?

Bundles offer simplicity — one provider, one bill, one point of contact for faults. For very small businesses with straightforward requirements, this convenience has real value. However, there are trade-offs:

• Price: Provider bundles are rarely the cheapest option when you compare the individual components separately
• Flexibility: Bundles tie broadband and phone to the same contract, so switching one service typically means switching both
• VoIP sophistication: BT's Digital Voice offering is relatively basic. Businesses with multiple lines, remote workers, or more complex call handling requirements will find a purpose-built hosted VoIP system more capable

When to Consider an Alternative

Businesses with more than 5–10 staff, multiple phone extensions, or remote workers are worth evaluating a hosted VoIP system separately from their broadband provider. A dedicated VoIP platform (such as a Microsoft Teams Calling or hosted PBX solution) paired with a standalone business broadband connection often delivers better capability and better value than an all-in-one bundle from BT.

AMVIA provides both business connectivity and hosted VoIP services, so we can look at your phone and broadband requirements together and recommend the combination that makes most sense for your size and budget.
