UK VoIP comparison: Virgin Media £15–£29/user, BT £13–£23/user, TalkTalk £7–£12/user. Features, migration, support models, and expert selection framework for business phone systems.
VoIP (Voice over Internet Protocol) enables businesses to run phone systems over internet connections rather than traditional PSTN/ISDN lines—reducing costs 40–70%, enabling remote work flexibility, and integrating communications with business applications (CRM, Microsoft Teams, Slack). UK market leaders—Virgin Media (£15–£29/user/month), BT (£13–£23/user), TalkTalk (£7–£12/user)—offer cloud-based systems with varying feature sets, support models, and integration capabilities. However, choosing based on headline pricing alone overlooks critical decision factors: implementation complexity (migration timelines 2–8 weeks), support quality (automated queues vs. direct expert access), feature alignment with actual business workflows (do you need video conferencing, mobile integration, CRM sync?), and total cost of ownership (setup fees, hardware costs, call packages). This guide compares major UK VoIP providers by pricing tiers, feature breakdowns, support models, explains decision criteria for small businesses vs. mid-market enterprises, addresses common migration concerns (number portability, downtime risk, staff training), and highlights why expert-led providers like AMVIA deliver superior outcomes through personalized implementation, ongoing optimization, and direct UK support rather than automated corporate systems prioritizing volume over business success.
VoIP converts voice into digital data packets transmitted over internet connections—bypassing traditional copper phone lines. Instead of separate "phone" and "data" infrastructure, VoIP unifies communications over single broadband connection, reducing costs and enabling advanced features impossible with legacy systems.
Key advantages: 40–70% cost reduction versus traditional phone lines (no per-line rental, cheaper call rates, bundled packages). Remote work enablement—employees take business number on mobile, laptop, any device. Integration with business apps—call logs attach to CRM records automatically, voicemail transcribes to email, video + phone unified in Teams. Scalability—add new users instantly versus weeks for traditional line installation.
Openreach is retiring traditional PSTN/ISDN phone networks by December 2027, forcing all UK businesses to migrate to IP-based systems. This creates urgency—businesses delaying VoIP migration will face rushed last-minute transitions, higher costs, and limited provider choice as 2027 approaches. Early movers secure better pricing, more implementation time, and proactive migration control.
Virgin Media offers two VoIP product lines: Enterprise Cloud Voice (large businesses 50+ users) and SME Cloud Voice (small/mid-market 5–50 users). Four pricing tiers with increasing feature complexity.
Functional: £15/user/month. Includes inclusive call package, standard on-site features (call directing, hunt groups, reporting), call management (waiting, hold, caller ID, blocking, pickup, transfer), voicemail, call forwarding.
Fixed: £18/user/month. Adds instant messaging and presence (see colleague availability status).
Collaborate: £21/user/month. Adds voice and video applications, softphone for smartphones/tablets.
Complete: £29/user/month. Full unified communications suite with advanced collaboration tools.
Virgin Media positioning: Mid-tier pricing, feature-rich at higher tiers, cable network dependency (availability limited to Virgin infrastructure areas—check coverage before committing). Support follows corporate queue model (8am–9pm weekdays, limited weekend availability).
BT offers three VoIP systems: BT Cloud Phone (small businesses up to 9 users), BT Cloud Voice (feature-rich for 5+ users), BT One Phone (mobile-first for businesses without central premises).
BT Cloud Phone Basic: £13/user/month. Entry-level hosted VoIP for up to 9 users. Includes core features (voicemail, call forwarding, basic reporting). Suitable for micro-businesses with simple phone needs.
BT Cloud Phone Connect: £23/user/month. Adds advanced collaboration features, mobile integration, enhanced reporting.
BT positioning: Broad UK coverage (largest infrastructure footprint), established brand trust, but premium pricing versus competitors. Support 24/7 for business customers, but escalation through multiple departments typical. Installation timelines 3–6 weeks standard.
TalkTalk offers Hosted Voice (VoIP cloud system routing calls through internet) and Mitel solutions (manufacturer-specific systems for larger deployments needing bespoke features).
TalkTalk Hosted Voice: £7/user/month (entry), £9/user/month (mid), £12/user/month (premium). Lowest pricing among major carriers. Integrates office and mobile handsets, low-cost pay-monthly model, no installation fees (promotional periods).
TalkTalk positioning: Budget leader—ideal for cost-conscious SMEs. Feature set less comprehensive than Virgin or BT at equivalent tiers but sufficient for standard business phone needs. Support standard business hours; limited 24/7 availability. Installation 2–4 weeks typical.
AMVIA is specialist VoIP provider trusted by Oracle, eHarmony, Holiday Inn, and hundreds of UK SMEs. Unlike volume-focused carriers, AMVIA matches solutions to specific business needs through consultative approach, expert implementation, and ongoing optimization.
AMVIA approach: Understand your operations first (call volume, remote work requirements, CRM integration needs, growth trajectory). Recommend optimal system and tier (not highest price, but best fit). Handle end-to-end migration (number portability, testing, staff training). Provide direct UK expert support (0333 733 8050, 90-second response guarantee, no voicemail). Optimize continuously based on actual usage patterns.
Pricing: Competitive with major carriers but includes expert implementation, migration support, and ongoing optimization versus DIY setup. Typical range £10–£25/user/month depending on feature requirements and call volume.
Voicemail, call forwarding, caller ID, call waiting, hold music, basic reporting. These are table stakes—every provider includes them. Not decision differentiators.
Hunt groups (incoming calls distributed across team automatically). Auto-attendant (professional greeting menu directing callers). Call recording (compliance-critical for financial services, healthcare). Instant messaging and presence (see colleague availability). Video conferencing integration. Mobile softphone apps (take business number on smartphone). CRM integration (call logs attach to customer records in Salesforce, HubSpot). Voicemail-to-email transcription. Analytics and reporting (call volume trends, average handle time, missed calls).
Decision criterion: Identify which advanced features your business actually needs (not "might use someday"). Financial services firm needs call recording for compliance; creative agency doesn't. Remote-heavy business needs mobile softphone; office-based doesn't. Match tier to actual requirements, not marketing feature lists.
VoIP systems integrating with Microsoft Teams, Salesforce, Slack, HubSpot, or other business apps deliver productivity multipliers—call history automatically logged, voicemails transcribed and attached to customer records, presence synced across platforms. Virgin Media and BT offer native Teams integration at higher tiers. TalkTalk integration is more limited. AMVIA configures deep integrations customized to your specific tech stack.
Virgin Media £15/user × 10 users = £150/month appears cheaper than AMVIA £18/user × 10 = £180/month. However, total cost includes: Setup/installation fees (Virgin/BT: £500–£1,500 depending on complexity; AMVIA often waives for annual contracts). Hardware costs (desk phones £50–£200 each; headsets £30–£100; some providers bundle, others charge separately). Call packages (inclusive minutes vary; overage charges £0.05–£0.15/minute add up fast). Support costs (automated systems create productivity loss waiting in queues; expert support prevents downtime).
10-person business, Virgin Media Functional (£15/user): £150/month + £1,000 setup + 10 desk phones @ £80 = £800 + £50/month call overages = Total year 1: £1,800 + £600 overages = £2,400. AMVIA equivalent (£18/user, setup waived, phones included): £180/month × 12 = £2,160. AMVIA saves £240 year 1 despite higher monthly rate.
DIY migration with Virgin/BT/TalkTalk: 1–2 days staff productivity loss during cutover (learning new system, troubleshooting configuration issues) × 10 staff × £25/hour × 8 hours = £2,000 productivity cost. Expert-led migration (AMVIA): handles cutover evenings/weekends, provides pre-migration training, validates testing before go-live = zero productivity loss. £2,000 saved.
Automated phone systems, 8–15 minute hold times typical, escalation through multiple departments, limited 24/7 availability. When VoIP system fails at 2pm Monday during peak call volume, you're in queue with hundreds of other customers. Resolution time: 4–8 hours best case.
Call 0333 733 8050, speak to live UK engineer within 90 seconds. No voicemail, no phone trees, no offshore routing. Engineer has full system access and decision authority—diagnoses root cause, implements fix immediately. Resolution time: 10–30 minutes typical. For revenue-dependent businesses (customer service centers, sales teams), this difference is material.
Can you keep existing business phone numbers when switching to VoIP? Yes—all UK providers support number portability. Process: submit porting request with current provider details, new VoIP provider coordinates transfer with Openreach, numbers migrate within 10–15 business days. No service interruption during transfer (old system stays active until new VoIP live, then automatic switchover).
VoIP requires reliable internet. If broadband fails, phone system becomes unavailable. Mitigation: deploy 4G backup (automatic failover to mobile network if broadband drops, ~£60–£95/month). For mission-critical phone operations (customer support centers), 4G backup is non-negotiable insurance.
New phone system = learning curve. DIY providers (Virgin, BT, TalkTalk) provide online documentation and webinars. Expert providers (AMVIA) conduct on-site or remote training sessions customized to your team, plus post-migration support ensuring staff comfortable with new features. Training investment prevents productivity loss and feature under-utilization.
You're in Virgin Media coverage area, need mid-tier features (video, collaboration), have IT expertise to handle DIY setup, prefer established brand, and can tolerate corporate support model.
You prioritize broad UK coverage, established brand trust, need 24/7 support availability, have budget for premium pricing, and require integration with BT's broader connectivity/security portfolio.
Budget is primary constraint, needs are basic (voice calls, voicemail, forwarding), business operates standard hours (limited 24/7 requirement), and DIY setup acceptable.
You value expert guidance over DIY, need migration handled end-to-end with zero downtime, require direct UK support (90-second response), want system optimized to actual workflows, prefer partnership approach over transactional vendor relationship, or operate in revenue-critical environment where phone system failure is unacceptable.
Depends on phone model. VoIP requires IP-capable phones (SIP protocol support). Older analog phones don't work directly but can connect via ATA (analog telephone adapter, ~£50–£100). Most businesses find upgrading to modern IP phones (£50–£200 each) more cost-effective than adapters.
Minimum 2Mbps per concurrent call. 10-person business with max 5 concurrent calls needs 10Mbps dedicated VoIP bandwidth. Recommended: 5–10Mbps per concurrent call to ensure quality during peak broadband usage. If broadband also handles cloud apps and video conferencing, add 30% buffer.
DIY providers (Virgin, BT, TalkTalk): 3–6 weeks from order to go-live. Expert providers (AMVIA): 2–4 weeks for standard deployments, 1–2 weeks for urgent migrations. Timeline includes number porting, hardware delivery, configuration, testing, and staff training.
VoIP becomes unavailable unless you have 4G backup (automatic failover to mobile network within seconds, maintaining phone connectivity during broadband outage). For mission-critical phone operations, 4G backup is essential—adds £60–£95/month but prevents revenue-killing phone downtime.
Audit current phone costs (line rental, call charges, maintenance). Calculate total annual spend. Identify must-have features (mobile integration? CRM sync? Call recording?). Call AMVIA at 0333 733 8050 for assessment: discuss requirements, receive personalized recommendations, understand migration roadmap. Most businesses move from assessment to implementation within 4 weeks.
UK VoIP market offers competitive pricing (£7–£29/user/month) and feature-rich systems from multiple providers. However, choosing based on headline pricing ignores critical success factors: implementation quality (preventing downtime during migration), support responsiveness (automated queues vs. direct expert access), feature alignment (matching tier to actual needs), and total cost of ownership (setup, hardware, training, ongoing optimization).
For businesses treating VoIP as strategic infrastructure—not commodity purchase—expert-led providers like AMVIA deliver measurably better outcomes through consultative approach, zero-downtime migration, and ongoing optimization ensuring system matches evolving business requirements.
