Business Phone and Broadband Bundles UK 2026: Compare and Save

If you’re running a small or medium-sized business in the UK, your phone and internet bills are probably two of your biggest recurring costs. Buying them separately means two contracts, two providers and two sets of price rises to deal with every year.

Business phone and broadband bundles solve that problem by combining both services under one roof. But with the PSTN switch-off approaching in 2027, the bundle landscape has changed dramatically. Traditional copper-based packages are disappearing, and modern fibre-plus-VoIP bundles are taking their place.

This guide compares every type of business phone and internet bundle available in 2026, breaks down real-world costs, and shows you exactly how to find the right package for your company.

What Is a Business Phone and Broadband Bundle?

A business phone and broadband bundle is a single package that includes both your internet connection and your telephone service. Instead of paying one provider for broadband and another for phone lines, you get everything on one bill with one contract.

Bundles have existed for years, but the technology behind them has shifted. In the past, bundles meant a copper phone line with ADSL broadband running over the same wire. Today, the best bundles pair fibre broadband (FTTP or FTTC) with a VoIP phone system that runs over your internet connection.

This matters because VoIP-based bundles are significantly cheaper to deliver, which means providers can pass on genuine savings rather than just repackaging the same old services at a slight discount.

Types of Business Phone and Broadband Bundles

1. Traditional Copper Bundles (Being Phased Out)

These combine an analogue phone line with ADSL or FTTC broadband. BT Business, Sky Business and TalkTalk Business have offered these for years. However, with Openreach retiring the copper network by 2027, these bundles are no longer available in many areas and will disappear entirely within the next 18 months.

Typical cost: £35–£55/month for one line plus broadband.
Best for: Businesses in areas without fibre who need a short-term solution.

2. Fibre Broadband + VoIP Bundles

The modern standard. You get a full-fibre (FTTP) or part-fibre (FTTC) broadband connection, and your phone system runs as a VoIP service over that connection. This is what most providers now recommend, and it’s where the real savings are.

Typical cost: £25–£45/month for broadband plus 1–5 VoIP users.
Best for: Most small and medium businesses. Scales easily as you grow.

3. Leased Line + SIP Trunk Bundles

For larger businesses or those needing guaranteed bandwidth, a leased line provides a dedicated internet connection with symmetrical speeds. Paired with SIP trunks connecting to your on-site PBX, this is the premium option.

Typical cost: £200–£500/month depending on speed and channels.
Best for: Businesses with 20+ employees, call centres, or those needing guaranteed uptime.

4. Mobile-Inclusive Bundles

Some providers now bundle broadband, VoIP and mobile SIMs into a single package. This is particularly useful for businesses with field-based staff who need seamless handoff between desk phones and mobiles.

Typical cost: £35–£60/month per user including mobile.
Best for: Businesses with remote or mobile workers.

Business Phone and Broadband Bundle Comparison Table

How Much Do Business Phone and Broadband Bundles Cost?

Costs vary significantly depending on the type of bundle, your broadband speed requirements and the number of phone users. Here’s what you can realistically expect to pay in 2026:

Small Business (1–5 Employees)

A fibre broadband connection (80–300 Mbps) with 1–5 VoIP extensions will typically cost £25–£45/month. At the lower end, you’re looking at a basic fibre connection with a simple cloud phone system. At the higher end, you’ll get faster speeds and more inclusive call minutes.

Medium Business (5–20 Employees)

You’ll likely need faster broadband (300+ Mbps) and a more feature-rich phone system with auto-attendant, call queues and CRM integration. Expect to pay £45–£120/month depending on the number of users and features required.

Larger Business (20+ Employees)

At this scale, a leased line or dedicated fibre connection paired with SIP trunking or an enterprise hosted VoIP platform is the norm. Costs range from £200–£500+/month, but the per-user cost actually decreases as you scale.

What Affects the Price?

• Broadband speed and type – FTTP is cheaper than leased line but less predictable
• Number of phone users – Most VoIP providers charge per user per month
• Call packages – Inclusive UK calls vs pay-as-you-go vs international bundles
• Contract length – Longer contracts usually mean lower monthly costs
• Hardware – Some bundles include desk phones; others require you to buy or rent them

Why VoIP + Fibre Is the Best Business Phone and Internet Bundle in 2026

The combination of full-fibre broadband and a cloud-hosted VoIP phone system has become the default recommendation for UK businesses, and for good reason:

Cost savings of 30–40%: VoIP calls cost a fraction of traditional line rental. There’s no per-line charge from Openreach, no ISDN channel fees, and calls between extensions are free. When you bundle VoIP with fibre from the same provider or a partner, the savings compound.

Future-proof technology: With the PSTN switch-off in 2027, every business will need an IP-based phone system. Switching now means you avoid the last-minute rush and potential service disruptions.

Flexibility and scalability: Adding a new user to a VoIP system takes minutes, not weeks. There’s no engineer visit, no new wiring, and no additional line rental. If you hire five new staff next month, you simply add five licences.

Advanced features included: Most VoIP bundles include features that would cost extra on a traditional system – call recording, voicemail-to-email, auto-attendant, mobile apps, video conferencing and detailed call analytics.

Work-from-anywhere capability: VoIP works on desk phones, laptops, tablets and smartphones. Your team can make and receive calls on their business number from anywhere with an internet connection, which is essential for hybrid working.

How to Compare Business Phone and Broadband Bundles

Not all bundles are created equal. Here’s what to check before signing up:

1. Check the Total Cost of Ownership

The headline monthly price rarely tells the full story. Ask about setup fees, hardware costs, call charges outside any inclusive package, and what happens to the price after any introductory period. A bundle that looks cheap at £30/month can easily cost £50+ once you add per-minute call charges and phone rental.

2. Verify Broadband Speeds at Your Premises

The speed advertised is the maximum, not what you’ll necessarily get. Ask the provider to run a line check for your specific postcode. If full fibre (FTTP) isn’t available, check whether Openreach has plans to roll it out to your area soon – it may be worth waiting a few months rather than locking into a long FTTC contract.

3. Understand the Phone System

Some bundles include a basic single-line VoIP service that’s little more than a digital replacement for your old analogue line. Others include a full cloud PBX with auto-attendant, call queues, ring groups and CRM integration. Make sure the phone element of the bundle actually meets your needs.

4. Check Contract Length and Exit Terms

Business broadband contracts typically run for 24 or 36 months. Some VoIP providers offer monthly rolling contracts, which gives you flexibility but may cost slightly more per month. Always check the early termination charges – some providers charge the remaining contract value in full.

5. Ask About Support and SLAs

When your phone and internet go down, your business stops. Check what support is included – is it UK-based? What are the response times? Is there a guaranteed fix time? Business-grade bundles should include at minimum next-business-day fault resolution.

How to Switch Your Business Phone and Broadband Bundle

Switching is simpler than most businesses expect. Here’s the process step by step:

Step 1: Audit Your Current Setup

List every phone line, broadband connection and associated cost. Note your contract end dates and any early termination fees. Check how many phone numbers you have and which ones you need to keep.

Step 2: Get Quotes from Multiple Providers

Don’t just compare headline prices. Ask for fully itemised quotes that include all setup fees, hardware, call charges and any price increases built into the contract. Getting three to five quotes gives you a solid basis for comparison.

Step 3: Choose Your Bundle and Place the Order

Once you’ve selected a provider, they’ll handle most of the technical work. If you’re porting existing phone numbers, this typically takes 5–10 working days. Broadband installation depends on whether you need a new fibre connection – existing connections can be switched in 10–14 days, while new FTTP installations may take 2–4 weeks.

Step 4: Set Up and Test

Before going live, test your new phone system thoroughly. Check call quality, test all features (voicemail, call forwarding, auto-attendant), and make sure every team member can log in and make calls. Most providers offer a parallel running period where both old and new systems work simultaneously.

Step 5: Cancel Your Old Services

Once everything is working, cancel your old phone and broadband contracts. Make sure all number ports have completed before doing this, and keep your old service active until you’ve confirmed everything works on the new system.

Frequently Asked Questions

Can I bundle business phone and broadband from different providers?

Yes, and sometimes this is the best approach. You can pair a fibre broadband deal from one provider with a VoIP phone system from another. The downside is managing two contracts and two support teams, but the upside is you can pick the best of each. Many VoIP providers are provider-agnostic and work over any broadband connection.

Is it worth bundling or should I buy separately?

For most businesses, bundling saves money and simplifies management. The exception is if you’ve found a particularly good deal on one service – for example, a very cheap fibre deal that doesn’t include phone. In that case, adding a standalone VoIP service on top may work out cheaper than a combined bundle from a more expensive provider.

What happens to my bundle during the PSTN switch-off?

If your current bundle includes a traditional copper phone line, it will need to be replaced before 2027. Your provider should contact you about migration options. If you’re already on a VoIP + fibre bundle, the switch-off won’t affect you at all – you’re already on the technology that’s replacing the old network.

Do I need special broadband for VoIP?

VoIP works over any broadband connection, but it performs best on fibre with at least 10 Mbps download and 1 Mbps upload per concurrent call. For a business with 5–10 simultaneous calls, a 100 Mbps fibre connection provides plenty of headroom. Quality of Service (QoS) settings on your router can prioritise voice traffic to ensure crystal-clear calls even when the connection is busy.

The Bottom Line

Business phone and broadband bundles are the smartest way to manage your communications costs in 2026. With the PSTN switch-off looming, now is the ideal time to move to a modern VoIP + fibre bundle that saves money, adds features and future-proofs your business.

The key is comparing like for like. Look beyond the headline price, check the total cost including calls and hardware, and make sure the phone system actually has the features your team needs. Whether you choose a big-name provider like BT or Virgin, or a specialist VoIP provider, bundling your business phone and internet together will almost always save you money.
