Business Phone & Broadband Bundles UK 2026: How to Save 15-30%
Business Phone & Broadband Bundles UK 2026: How to Save 15-30%
Last updated: March 2026
If your business is paying for mobile phones, a landline system, and broadband from three different providers, you are almost certainly overpaying. Bundling these services together, either through a single network provider or by combining mobile and VoIP packages, can reduce your total telecoms bill by 15-30%, while simplifying your account management and giving you a single point of contact when something goes wrong.
The UK business telecoms market has shifted dramatically in the last two years. The PSTN switch-off, the rise of hosted VoIP, and aggressive bundle pricing from all four major networks mean that 2026 is the best time in a decade to consolidate your business communications. Whether you are a sole trader working from home or a growing company with fifty employees across multiple sites, there is a bundle that will save you money.
This guide breaks down every option, compares the real costs with detailed tables, and helps you work out exactly how much your business could save. As an OFCOM-regulated comparison service with a 4.3/5 Trustpilot rating, we have been helping UK businesses cut their telecoms costs since 2008. We have no affiliation with any single network, our job is to find you the best deal.
What Are Business Phone and Broadband Bundles?
A business phone and broadband bundle combines two or more of your core communication services into a single package from one provider. Instead of paying separately for your mobile phones, business broadband, and office phone system, you pay a single monthly fee that covers everything, usually at a significant discount compared to buying each service individually.
The most common bundle types in 2026 are:
- Mobile + broadband: Your business SIMs and your office internet from the same network
- Mobile + VoIP: Your mobile phones and a hosted VoIP phone system from a single provider
- Triple bundle (mobile + broadband + VoIP): Everything together, mobile, internet, and office phone system
- Mobile + broadband + cloud services: Some providers now bundle Microsoft 365 or Google Workspace alongside connectivity
The savings come from two places. First, providers offer genuine discounts for bundling, typically 10-20% off the combined retail price. Second, bundling eliminates duplication. Many businesses pay for a traditional landline they barely use alongside a VoIP system that already handles calls. Consolidating removes that wasted spend.
Bundle Options by Network (March 2026)
Each of the four major UK networks now offers some form of business bundle. Here is what each provides and where they are strongest.
EE Business Bundles
EE, backed by BT Group, offers the most comprehensive bundling options of any UK network. This is largely because BT provides business broadband and Openreach supplies the underlying infrastructure, giving EE a genuine end-to-end proposition.
What EE bundles include:
- Business mobile SIMs (5G included on all plans)
- BT Business broadband (fibre, full fibre, and 5G broadband)
- Business phone lines and hosted VoIP through BT
- Optional Microsoft 365 licensing
EE's key advantage is their integrated billing and support. One account manager, one bill, one support line. For businesses that have struggled with finger-pointing between different providers when something goes wrong, this simplicity is worth a premium. Their business mobile plans are already competitively priced, and bundling with BT broadband brings additional per-line discounts.
Vodafone Business Bundles
Vodafone has invested heavily in their converged business offering, and the Three merger has expanded their capabilities. Vodafone One Net is their integrated communications platform that combines mobile, fixed-line, and broadband into a unified system.
What Vodafone bundles include:
- Business mobile SIMs with 5G
- Vodafone Business broadband (full fibre available in many areas)
- Vodafone One Net Express (hosted VoIP for small businesses)
- Optional cloud and security services
Vodafone's strength is in their One Net platform, which genuinely integrates mobile and desk phones so that a call to your office number can ring on both your desk phone and your mobile simultaneously. For businesses that want a professional phone system without the complexity, Vodafone's bundle is compelling. Explore their business mobile deals as a starting point.
Three Business Bundles
Three's bundle offering is more focused. Their core strength remains mobile and mobile broadband, and they offer competitive bundles combining mobile SIMs with 5G broadband, particularly attractive for businesses that can use 5G as their primary internet connection.
What Three bundles include:
- Business mobile SIMs with 5G
- 5G broadband (home and business routers)
- Limited VoIP integration through partners
Three's bundle sweet spot is businesses in 5G coverage areas that can replace their fixed-line broadband entirely. A 5G business broadband router from Three, combined with their mobile plans, can eliminate your broadband bill while providing speeds that match or exceed fibre. Check their business mobile deals for the latest bundle pricing.
O2 Business Bundles
O2 offers business bundles through their partnership ecosystem. While O2 does not provide broadband directly, they bundle mobile with VoIP services and have partnerships with broadband providers to offer consolidated packages.
What O2 bundles include:
- Business mobile SIMs with 5G and Starlink satellite backup
- O2 Business VoIP solutions
- Partner broadband through selected ISPs
- Microsoft Teams Phone integration
O2's Starlink satellite connectivity makes their bundles uniquely attractive for rural businesses that struggle with broadband speeds. Combining an O2 mobile plan with a 5G or satellite-enabled router can solve connectivity challenges that no other provider can match. See O2's business offerings for current bundle options.
Cost Comparison: Bundled vs Separate (2026 Prices)
This is where the numbers tell the story. We have compared the cost of buying services separately versus bundling them together for three typical business sizes.
Sole Trader / Micro Business (1-2 people)
| Service | Separate Cost | Bundled Cost | Saving |
|---|---|---|---|
| 1 business mobile SIM (20GB) | £18/mo | Included | , |
| Business broadband (fibre, 80Mbps) | £30/mo | Included | , |
| VoIP phone line (1 user) | £12/mo | Included | , |
| Total monthly cost | £60/mo | £45-50/mo | £10-15/mo (17-25%) |
| Annual cost | £720 | £540-600 | £120-180/year |
Small Business (5-10 people)
| Service | Separate Cost | Bundled Cost | Saving |
|---|---|---|---|
| 5 business mobile SIMs (20GB each) | £75/mo | Included | , |
| Business broadband (full fibre, 300Mbps) | £45/mo | Included | , |
| VoIP phone system (5 users) | £50/mo | Included | , |
| Total monthly cost | £170/mo | £125-140/mo | £30-45/mo (18-26%) |
| Annual cost | £2,040 | £1,500-1,680 | £360-540/year |
Medium Business (20-50 people)
| Service | Separate Cost | Bundled Cost | Saving |
|---|---|---|---|
| 20 business mobile SIMs (30GB each) | £260/mo | Included | , |
| Business broadband (leased line, 500Mbps) | £200/mo | Included | , |
| VoIP phone system (20 users) | £180/mo | Included | , |
| Total monthly cost | £640/mo | £450-540/mo | £100-190/mo (16-30%) |
| Annual cost | £7,680 | £5,400-6,480 | £1,200-2,280/year |
Prices are indicative based on published rates as of March 2026. Actual pricing varies by provider, location, and negotiation. Multi-year contracts typically offer deeper discounts.
The pattern is clear: the more services you bundle and the larger your team, the greater the absolute saving. For a 20-person business, bundling can save over £2,000 per year, money that goes straight to your bottom line.
Who Benefits Most from Bundling?
Bundling is not the right move for every business. Here is an honest assessment of who benefits most and who should be cautious.
Best Candidates for Bundling
Growing businesses that are adding staff regularly benefit from having a single provider who can add mobile lines, VoIP extensions, and broadband capacity without coordinating between multiple companies.
Businesses with expiring contracts have the perfect opportunity to consolidate. If your broadband, mobile, and phone contracts all renew at different times, negotiate with your chosen bundle provider to buy out any remaining contract terms, the long-term savings usually justify the early exit fees.
Companies frustrated with multiple providers often find that the biggest benefit of bundling is not the cost saving but the operational simplicity. One bill, one support number, one account manager.
Businesses in 5G coverage areas can save the most by replacing fixed-line broadband with 5G mobile broadband, eliminating one entire service from the bill.
When Bundling Might Not Be Right
Businesses with a recently signed long-term broadband contract may face early termination fees that eat into the bundle savings. In these cases, it may be worth waiting until the contract expires.
Companies with specialist requirements. such as a leased line for hosting servers on-premises, may find that bundle providers cannot match the specification they need for every service.
Very large enterprises (100+ employees) often get better pricing by negotiating each service independently with specialist providers, as the volume discounts at that scale can exceed bundle savings.
VoIP and Mobile Bundles: The Smart Combination
With the PSTN switch-off in 2027, every UK business that currently uses a traditional landline will need to move to a VoIP-based phone system. This creates a natural bundling opportunity.
Why VoIP + Mobile Makes Sense
A hosted VoIP system replaces your traditional phone lines with internet-based calling. When you bundle this with your business mobiles, you get features that are impossible with separate systems:
- Single number reach: Calls to your business number ring on both your desk phone and your mobile. No more missed calls.
- Unified voicemail: One voicemail box accessible from any device.
- Seamless transfers: Transfer a call from your desk phone to your mobile mid-conversation, with no interruption.
- Single directory: One contact list shared across all devices.
- Consolidated billing: One bill for all voice services.
VoIP + Mobile Bundle Pricing
| Provider | VoIP per user/mo | Mobile SIM/mo | Bundle price per user/mo | Bundle saving |
|---|---|---|---|---|
| EE/BT | £12-18 | £12-20 | £20-30 | 15-20% |
| Vodafone One Net | £10-15 | £10-18 | £16-26 | 18-22% |
| O2 + Partner VoIP | £8-14 | £8-16 | £14-24 | 12-18% |
| Three + Partner VoIP | £8-12 | £8-15 | £13-22 | 15-20% |
Pricing varies by data allowance, call minutes, and features selected. Volume discounts apply for larger teams.
Microsoft Teams Phone Integration
Many businesses already use Microsoft Teams for messaging and video calls. Adding Teams Phone (which replaces your traditional phone system entirely) is increasingly available as part of mobile bundles. You keep your existing business number, make and receive external calls through Teams, and manage everything through a single interface your team already knows.
EE and Vodafone both offer Teams Phone as an add-on to their business bundles, typically for an additional £6-10 per user per month. For businesses already paying for Microsoft 365, this can be the most cost-effective VoIP option available.
How to Switch to a Bundle: Step-by-Step Guide
Switching to a bundled package does not have to be complicated, but it does require some planning to avoid service disruptions. Here is the process we recommend.
Step 1: Audit Your Current Telecoms Spend
Before you can calculate savings, you need to know exactly what you are paying now. Gather:
- All mobile phone bills (per line costs, data usage, out-of-plan charges)
- Broadband bills (speed, contract end date, any overage charges)
- Phone system costs (line rental, call charges, maintenance fees)
- Any other telecoms costs (conference call services, fax lines, alarm connections)
Add everything up. This is your baseline, any bundle needs to beat this number.
Step 2: Check Your Contract End Dates
Each service will have its own contract end date. Note these down:
- Mobile contracts (each line may differ)
- Broadband contract
- Phone system contract or lease
Early termination fees vary but are typically the remaining monthly charges for the rest of the contract. Some bundle providers will cover these fees as an incentive to switch.
Step 3: Assess Your Requirements
Before requesting quotes, define what you actually need:
- Number of mobile lines and data per line
- Broadband speed requirements (consider growth over the contract term)
- Number of phone extensions / VoIP users
- Any specific features (call recording, auto-attendant, international calls)
- Geographic coverage requirements
Step 4: Get Quotes from Multiple Providers
This is where we come in. Rather than approaching each network individually, use our free comparison service to get quotes from all major providers simultaneously. We compare like-for-like to ensure you are seeing genuine savings, not just cheaper headline prices with hidden extras.
Step 5: Number Porting
Your business phone numbers are portable. Whether it is your landline number, your mobile numbers, or your VoIP numbers, you can take them with you when you switch. The porting process typically takes 1-5 business days for mobile numbers and 5-10 business days for landline numbers. A good provider will manage this entire process for you.
Step 6: Installation and Switchover
For broadband, the switchover is usually seamless if you are staying on the Openreach network (most fibre and full fibre connections). VoIP systems can typically be set up before your old phone system is disconnected, allowing a period of parallel running. Mobile SIMs can be activated immediately with your existing numbers ported over.
Broadband Options Within Bundles
Not all broadband is equal, and the right choice depends on your business size and usage patterns.
Fibre Broadband (FTTC)
Speeds: 36-80Mbps download, 10-20Mbps upload Best for: Sole traders and micro businesses with light usage Typical bundle cost: £25-35/mo as part of a bundle
Standard fibre broadband uses the existing copper network for the last stretch to your premises. It is widely available and affordable, but speeds are limited and can vary depending on your distance from the cabinet.
Full Fibre Broadband (FTTP)
Speeds: 100Mbps to 1Gbps download, 50-115Mbps upload Best for: Small to medium businesses, especially those using cloud services and VoIP Typical bundle cost: £35-60/mo as part of a bundle
Full fibre runs fibre optic cable directly to your premises, delivering consistent speeds regardless of distance. Availability has expanded rapidly and now covers over 60% of UK premises.
5G Broadband
Speeds: 150-300Mbps download (typical), up to 1Gbps peak Best for: Businesses in 5G coverage areas wanting to avoid installation and fixed contracts Typical bundle cost: £25-40/mo as part of a mobile bundle
5G broadband uses a router with a SIM card instead of a wired connection. No installation required, and you can take it with you if you move premises. The trade-off is that speeds are variable and dependent on network congestion.
Leased Lines
Speeds: 100Mbps to 10Gbps, symmetric (same upload and download) Best for: Medium to large businesses with critical connectivity requirements Typical bundle cost: £150-400/mo as part of a bundle
A leased line is a dedicated connection that is not shared with other users. Speeds are guaranteed and symmetric. The cost is significantly higher, but for businesses where connectivity is mission-critical, the reliability justifies the premium.
Broadband Comparison Within Bundles
| Broadband Type | Download Speed | Upload Speed | Availability | Monthly Cost (bundled) |
|---|---|---|---|---|
| Fibre (FTTC) | 36-80 Mbps | 10-20 Mbps | 95%+ of UK | £25-35 |
| Full Fibre (FTTP) | 100-1,000 Mbps | 50-115 Mbps | ~60% of UK | £35-60 |
| 5G Broadband | 150-300 Mbps | 30-70 Mbps | ~45% of UK | £25-40 |
| Leased Line | 100-10,000 Mbps | Same as download | Most business areas | £150-400 |
Hidden Costs to Watch Out For
Bundles save money, but only if you understand the full pricing. Watch for these common traps:
Installation fees: Some bundles have upfront installation costs for broadband or VoIP equipment. These should be clearly stated in the quote. Ask if they can be waived or spread across the contract term.
Out-of-bundle charges: Check what happens when you exceed your data allowance or call minutes. Some bundles charge premium rates for out-of-plan usage.
Price increases during contract: Most UK telecoms providers increase prices annually by CPI + a fixed percentage (typically 3.9%). Check the price increase clause in any contract. A £40/mo bundle today could be £46/mo by year two of a 24-month contract.
Equipment costs: VoIP desk phones, routers, and other equipment may be included, leased, or charged separately. Clarify this before signing.
Early termination fees: If you need to downsize or switch during the contract, early exit fees can be substantial. Understand the terms before committing.
Frequently Asked Questions
How much can I realistically save by bundling business phone and broadband?
Most businesses save between 15% and 30% compared to buying each service separately. The exact saving depends on your current spend, the number of services you consolidate, and the size of your team. A typical five-person business saves £360-540 per year. Larger businesses with 20+ employees can save over £2,000 annually.
Can I keep my existing phone numbers when switching to a bundle?
Yes. All UK business phone numbers (mobile, landline, and VoIP) are portable. Your new provider will manage the porting process, which typically takes 1-5 business days for mobile numbers and 5-10 business days for landline numbers. There should be no period where your numbers are unavailable.
Do I need to switch all services at once, or can I phase the transition?
You can phase the transition. Many businesses start by bundling mobile and broadband, then add VoIP when their existing phone contract expires. A good provider will work with your existing contract timelines to create a migration plan that avoids early termination fees wherever possible.
What happens if the broadband in my bundle goes down? Does the phone system stop working too?
If your VoIP phone system runs over your bundled broadband, a broadband outage will affect your phones. However, most VoIP systems include automatic failover to mobile, calls are redirected to your mobile phones until broadband is restored. Some bundles include 4G/5G backup routers that activate automatically during a broadband outage.
Are bundle contracts longer than individual service contracts?
Bundle contracts are typically 24 months, which is the same as most individual broadband and mobile contracts. Some providers offer 12-month or even 30-day rolling bundle contracts, but these come at a higher monthly cost. The 24-month commitment is usually where the best value lies.
Is VoIP reliable enough to replace my traditional phone line?
Yes. Modern hosted VoIP systems deliver call quality that is indistinguishable from traditional landlines when running over a stable broadband connection. With the PSTN switch-off in 2027, every UK business will need to move to VoIP regardless, bundling it now means you get ahead of the curve. Read our complete VoIP guide for more detail.
Can I add or remove lines during a bundle contract?
Most bundle contracts allow you to add lines at any time, with new lines matching the remaining contract term. Removing lines is more restricted, some providers allow you to reduce by a small number without penalty, while others treat each line as a separate commitment. Always check the flexibility terms before signing.
Should I choose the same provider for everything, or mix and match?
For maximum savings and simplicity, a single provider is usually best. However, if you have a specific requirement that one provider handles significantly better than others, such as a particular broadband speed or a specialist VoIP feature, mixing can make sense. The trade-off is managing multiple bills and support contacts.
How does 5G broadband compare to fibre in a bundle?
5G broadband typically delivers speeds comparable to fibre (150-300Mbps download) without requiring installation or a fixed line. It works well for businesses in good 5G coverage areas and offers more flexibility, you can move it to new premises instantly. The downsides are speed variability during peak congestion and dependence on 5G coverage at your location.
