UK-Based Dedicated Support
A small business phone system is a communication platform that allows your team to make and receive calls professionally across desk phones, mobiles, laptops, and office devices. Today, most UK SMEs choose VoIP (Voice over Internet Protocol) because it’s cheaper, more flexible, and future‑proof compared to traditional landlines.
What Is a Small Business Phone System?
Types of Office Phone Systems
VoIP phone systems – cloud‑based, flexible, low‑cost, ideal for small businesses
Hosted PBX systems – managed externally, great for teams without IT staff
On‑premise PBX – physical hardware in your office (rare for small offices today)
Hybrid systems – mix of VoIP + existing hardware
“Finding the right modern telephony architecture is critical for growth. At Stride, we’ve designed our small business solutions to be a “force multiplier,” replacing inadequate traditional plans with VoIP technology that eliminates high costs.
Stride Insight: We’ve found that 40% of UK startups over-spend on complex systems they don’t yet need; we recommend starting with a ‘Features-First’ approach rather than paying for excess user capacity.”

Quick Comparison: Top 7 Small Business Phone Systems (2026)
When comparing the best small business phone system options in the UK, it is vital to look beyond just the monthly cost. With the PSTN switch-off approaching, your choice should balance ease of use with local technical reliability.
In our experience with UK business networks, many global providers offer great software but lack the “on-the-ground” support needed during complex migrations. The table below highlights how the leading platforms stack up for SME requirements.
| Provider | Starting Price | Best For | UK Support Level | PSTN Ready? | Rating |
|---|---|---|---|---|---|
| Stride Communications | £11.95/user | UK SMEs (Simplicity) | 24/7 UK-Based Humans | Yes (Full Audit) | |
| RingCentral | £12.99/user | Global Scalability | Ticket-based / Global | Automated | |
| Vonage | £9.99/user | Micro-Startups | App-based | Automated | |
| 8x8 | £10.00/user | Remote Teams | Tiered / Online | Yes | |
| Mitel MiCloud | £10.50/user | Hybrid Work | Dealer Network | Yes | |
| Gamma Horizon | £11.00/user | Enterprises | Channel Partner Only | Yes | |
| BT Cloud Voice | £12.00/user | BT Customers | Call Centre | Included |
Why These Ratings Matter for Your Business
Choosing a provider is about more than a feature list. For most firms with 1–10 users, the “Ease of Use” and “Growth” factors are the highest priority.
Stride Communications: Positioned as the specialist for those who want a managed UK VoIP provider experience without the enterprise complexity.
Global Brands: While excellent for international scale, brands like RingCentral or Vonage often utilize automated migration tools which may not account for local UK hardware quirks.
Why UK Small Businesses Are Switching to VoIP
The needs of a startup or small to medium enterprise (SME) are distinct from those of a large corporation. You need maximum functionality for a minimal budget, and critically, the solution must be ready to use today. This section addresses the core pain points: high costs, complexity, and a lack of mobility.
Comparison: Traditional Landline vs. Stride Hosted VoIP
Traditional phone systems (analogue lines, on-premise PBXs) involve expensive capital expenditure (CAPEX), complicated installation, and long maintenance contracts. Cloud VoIP (Voice over IP) eliminates all these barriers, delivering the solution via the internet using your existing broadband package, providing essential operational flexibility.
To understand the core technology and full feature set, explore our main pillar page on the Cloud Phone System.
| Feature | Legacy Phone System | Cloud VoIP (Stride) | Small Business Benefit |
|---|---|---|---|
| Setup Speed | Weeks (Engineer required) | Minutes (Self-Service/Instant) | Zero Downtime; Start trading immediately. |
| Initial Cost | High (CAPEX for hardware) | Zero Upfront Cost (Subscription based) | Protect Working Capital; Use OPEX model. |
| Scalability | Fixed capacity, expensive to upgrade | Instant (Add users via an app) | Grow without Penalty; Pay only for what you need. |
| Mobility | Requires diverting calls | Full Mobile/Desktop App | Work From Anywhere (WFA); Ideal for hybrid or home workers. |
| 2027 Ready? | NO (Being switched off) | YES (Fully Future-Proof) | Stay compliant and operational long‑term |
Benefits of Office Phone Systems for Small Businesses
The shift to a per-user, per-month operational expenditure (OPEX) model is essential for small businesses managing cash flow. Our small business plans start from just £11.95 per user/month, providing a professional UK phone number and core features for less than the cost of a typical mobile contract.
- Eliminate Line Rental: Stop paying high monthly fees for traditional copper lines. The system uses your existing internet connection.
- Affordable Call Bundles: Choose a plan with Unlimited UK Mobile and Landline Calls for a fixed price, eliminating bill shock and allowing for easy budgeting.
- No Engineer Fees: Since the system is hosted in the cloud, all updates and repairs are managed remotely by the provider, delivering measurable ROI instantly.
- Professional Image: Auto‑attendants, call queues, and business numbers make even micro‑teams look established.
- Work Anywhere: Staff can answer calls from mobiles, laptops, or desk phones.
- Future‑Proofing: VoIP ensures your business is ready for the 2027 landline shutdown.
- Advanced Features: Analytics, call recording, and integrations help small teams operate like large enterprises.
🛑 The "Why Now?" Urgency: The 2027 PSTN Switch-Off
If your business currently relies on a traditional copper landline, you are running on borrowed time. Openreach is actively retiring the Public Switched Telephone Network (PSTN), meaning analogue phone lines will cease to work by January 2027.
What this means for your business:
Stop-Sell is Active: In many areas across the UK, you can no longer buy new traditional phone lines.
Forced Migration: Businesses that wait until late 2026 will face a “migration bottleneck,” risking downtime and higher costs.
Digital Upgrade: Modern office telephone systems use your internet connection to make calls, offering superior quality and flexibility.
Stride Insight: Don’t panic—upgrade. Switching to our hosted solution instantly future-proofs your business. You keep your number, but you lose the old copper wire maintenance costs.

Converter Box Option: For businesses that rely on a single analogue device (e.g., a credit card terminal or old fax machine), the Foundation License offers an optional BT Analogue to VoIP Converter box (£69 one-off), allowing the device to work over the internet during the transition phase.
Next-Gen AI VoIP for SMEs: Transcripts, Summaries, and CRM Automation

Expert FAQ: Small Business Phone System
How can a purpose-built phone system solve the communication challenges of a small business?
A purpose-built phone system solves small business challenges by replacing expensive, inadequate traditional plans with VoIP technology that acts as a “force multiplier.” This upgrade addresses three critical areas:
Budget & Scale: It eliminates the drain of traditional phone costs, providing enterprise-grade features without the high price tag.
Operational Efficiency: It prevents missed calls and client confusion by ensuring a professional presence regardless of team location.
Strategic Growth: By selecting an “appropriately featured” system—rather than just the most complex one—businesses gain a scalable, straightforward tool that turns a daily utility into a competitive edge.
What is the best phone system for a small business?
The best phone system for most small businesses is a cloud-hosted VoIP system. It offers the best balance of low upfront costs, advanced features (like IVR and call recording), and the flexibility to work from anywhere. Popular choices often include platforms that integrate voice, video, and messaging into one app.
Which is the best small business phone system for remote working?
Systems built on a “Mobile-First” architecture are best for remote work. These allow employees to use their business identity on personal devices via secure apps. Features like “Presence” (seeing who is online) and seamless call flipping between devices are essential for distributed teams.
How can a small business save money on a business telephone system?
Small businesses save money by switching from traditional BT lines to VoIP, which typically reduces monthly bills by 30-50%. Costs are further lowered by eliminating maintenance contracts for physical hardware and utilizing “inclusive minute” bundles that cover UK landline and mobile calls.
Are small business phone systems reliable?
Yes, modern cloud systems boast “five-nines” (99.999%) uptime. Because the “brain” of the phone system lives in redundant data centers rather than a box on your office wall, your system stays active even if your office suffers a power cut or local internet outage.
How to set up a small business phone system?
Setting up a modern system involves four streamlined steps:
- Run a bandwidth test: Ensure your internet connection is stable and capable of handling voice data. For high-density teams or offices with heavy data usage, we recommend reviewing our VoIP Connectivity & QoS Guide to understand how to prioritize voice traffic and eliminate jitter.
- Choose your provider and numbers: Pick a provider that aligns with your growth plans. You can select new virtual numbers or port your existing UK geographic (01/02) numbers to the cloud.
- Configure your call flow: Design your “digital reception.” Decide how incoming calls should ring—whether through automated IVR menus, specific ring groups, or time-of-day routing.
- Set up your devices: Simply install the mobile or desktop apps, or connect pre-configured IP phones to your router. If you prefer a hands-off approach, Stride offers a professional VoIP Phone System Installation service where our UK-based engineers handle the entire technical migration for you.
What is the main difference between Cloud VoIP and a traditional landline for a small business?
Cloud VoIP replaces the high capital expenditure (CAPEX) of hardware and the monthly cost of physical line rental with a flexible, low-cost operational expenditure (OPEX) subscription. It also provides essential mobility, allowing staff to use their business number on mobile apps from any location.
Is a fast, dedicated internet connection required for Small Business VoIP?
VoIP requires a stable broadband connection, but the bandwidth requirement is surprisingly low—approximately 0.1 Mbps per simultaneous call. Most standard UK fibre broadband connections are more than sufficient for a small business of up to 10 users, as long as the connection is reliable.
Will I lose my existing business phone number when I switch to Stride?
No, absolutely not. We manage the entire, free process of number porting your existing geographic (01/02) or national (03) number to our cloud platform, ensuring zero downtime or interruption to your service. We handle the process start-to-finish.
What happens to my calls if the office loses power or the internet goes down?
Because the entire system is hosted in the cloud, it remains active. We automatically configure disaster recovery to instantly forward all incoming calls to a designated mobile number or a team member’s mobile app, guaranteeing you never miss a critical lead, even during a local outage.
Can I integrate my Small Business Phone System with my CRM?
Yes. Our Standard and Enterprise licenses offer robust integration options, including Click-to-Dial functionality with popular CRM platforms, saving your sales and support teams significant time on a daily basis.
How secure is the UK's best small business phone system?
Leading UK systems are highly secure, utilizing end-to-end encryption (SRTP/TLS) and multi-factor authentication (MFA). Since the UK is phasing out the PSTN (landline) network by 2027, modern digital systems are also more resilient against physical line tampering and fraud.
Can I use my personal mobile for business calls?
Yes! Our mobile app lets you make and receive calls using your professional business number, keeping your personal number private.
How long does setup take?
Most small business systems are live within 24 hours. There is no need for an engineer to visit your premises.
Can I add users later?
Yes, instantly. You can add a new user in our portal, and they can be live with a new extension in minutes. This is perfect for seasonal businesses or rapidly growing startups.
