Top 10 UK Virtual Phone Providers for Small Businesses in 2026

Best UK virtual number providers for SMBs: 1. CloudTalk, 2. RingCentral, 3. Dialpad, 4. CallHippo & more. Scored on features, integrations, and price.                                                  

Which UK Virtual Phone Number Provider Is Best for SMBs? 10 Options Ranked for 2026

The optimal UK virtual phone number provider for a small or medium-sized business depends entirely on how the company utilizes its telephone lines: whether it requires a single number diverted to a mobile device, a shared line for a compact staff, or a comprehensive calling suite for outbound sales and customer service operations. Utilizing a UK virtual phone number provides enterprises with local (01/02), national (03), freephone (0800/0808), or mobile (07) digits that connect directly through software applications, IP desk handsets, or mobile devices rather than traditional copper wire infrastructure.

A multitude of UK small businesses must transition their telephony setups promptly due to the ongoing retirement of the traditional analogue landline network, with the complete Digital Voice migration deadline scheduled for January 2027. Cloud-based communications providers offering UK virtual numbers effectively replace legacy copper infrastructure entirely without requiring new physical cabling.

What are the best UK virtual phone number providers for SMBs?

CloudTalk holds the position of the top-ranked UK virtual phone number provider for SMBs, achieving an overall score of 9.5 out of 10, followed closely by RingCentral at 8.5 and Dialpad at 8.0. The complete ranking list is as follows:

• CloudTalk (9.5/10): best for SMB sales and support teams, with all four UK number types, IVR on every plan and 100+ integrations including HubSpot and Salesforce

• RingCentral (8.5/10): best for multi-site calls, meetings and fax, from £12.99 per user/month

• Dialpad (8.0/10): best for unlimited UK calling with AI transcripts, from £12 per user/month

• CallHippo (7.6/10): best for an omnichannel inbox covering SMS, WhatsApp and social messages

• Vonage (6.5/10): best for a landline number and a 07 business mobile on one eSIM

• 8×8 (6.5/10): best for multi-site and regulated organisations that need enterprise PBX controls

• bOnline (6.4/10): best for a first business line, from £7 per user/month

• AVOXI (6.4/10): best for adding UK numbers to Microsoft Teams or a contact centre platform

• SwitchboardFREE (6.0/10): best for contract-free number diversion with call whisper

• Virtual Landline (5.6/10): best for the cheapest single-user divert, from £3.75 per number ex VAT

How were these UK virtual phone number providers ranked?

Every individual provider is evaluated on a scale from 1 to 10 across five distinct criteria based explicitly on details published on their official websites. These weighted scores are tallied to generate an aggregate score out of 10, with ties automatically resolved in favor of the vendor possessing the superior pricing score.

• UK number types (20%): local 01/02, national 03, freephone 0800/0808 and mobile 07. A 10 means all four plus international numbers; a 6 means local and one other type. Only 07 numbers support SMS and WhatsApp.

• Calling features (25%): IVR, queues, recording, routing and AI tools on the plan an SMB actually buys. A 10 means all of them on the entry plan; a 4 means divert only. This is weighted highest because routing decides whether a call reaches the right person.

• Integrations (20%): named CRM and helpdesk integrations and the total count. A 10 means 100+ included in the plan; a 2 means none published.

• Pricing (20%): published prices, the entry cost and add-ons such as per-number fees or per-minute diversion. A 9 means published GBP tiers; a 3 means quote only.

• Setup and flexibility (15%): free trial, card requirement, billing options and minimum contract. A 9 means a no-card trial or no contract; a 4 means a quote with no trial.

Worked example: CloudTalk scores (10 × 20%) + (10 × 25%) + (10 × 20%) + (8 × 20%) + (9 × 15%) = 9.45, shown as 9.5.

How do UK virtual phone number providers compare on price and number types?

Published entry prices reflect costs per user per month based on annual commitments unless noted otherwise, and exclude Value Added Tax (VAT).

CloudTalk, CallHippo, and AVOXI do not display their UK tariffs in British Pounds; consequently, their figures are presented in United States Dollars exactly as specified on their respective corporate sites. The actual amount incurred in pounds by a UK enterprise utilizing these three platforms will fluctuate depending on the prevailing currency exchange rate at the time of billing.

Which are the 10 best UK virtual phone number providers for SMBs?

The top 10 virtual number solutions for smaller companies are examined below in sequential order, ranging from CloudTalk (9.5/10) down to Virtual Landline (5.6/10). Each review maintains a consistent layout covering an overview, rationale for the assigned ranking, supported UK number types, core capabilities, integrations, ideal use cases, relevant industries, target audiences, and structured pricing details.

1. CloudTalk: best UK virtual phone number provider for sales and support teams

CloudTalk operates as the leading UK virtual phone number service for SMB sales and support groups requiring advanced functionality beyond simple call forwarding—such as local UK presence, intelligent routing, and CRM-integrated telephony managed inside a singular cloud environment or via an AI voice agent. It proves equally useful for domestic British organizations and international enterprises targeting the UK market, as all regional and national number variations are accessible through a single dashboard operating across computers and mobile handsets.

The factor separating CloudTalk from basic number-forwarding services is its automated workflow processing after a call establishes connection. Calls route intelligently according to employee expertise or predefined schedules, synchronize customer interactions directly to CRM platforms, and can even be handled autonomously by CloudTalk’s round-the-clock AI voice agent outside standard working hours, enabling compact teams to handle call volumes comparable to much larger departments.

Why CloudTalk ranks #1 (9.5/10): CloudTalk is the only provider in this ranking that publishes all four UK number types (local, 03, 0800/0808 and 07) plus numbers in 160+ countries, includes IVR and skill-based routing on every plan, and connects to 100+ tools, naming HubSpot, Salesforce and Pipedrive. It runs at 99.999% platform availability. CloudTalk loses points only on pricing, because UK numbers ($6 each) are billed on top of the user plan.

UK number types

• Local geographic numbers (London 020, Manchester 0161, Edinburgh 0131 and other area codes)

• National 03 numbers

• Freephone 0800 and 0808 numbers (reachable from within the UK)

• Mobile +44 7 numbers with two-way SMS and WhatsApp eligibility

• Local numbers in 160+ other countries from the same account

Key features

• IVR, call flow designer and skill-based routing on every plan

• Ring groups, call queues and queue callback

• Call recording, with unlimited storage from the Essential plan

• Power and parallel dialers for outbound sales teams

• AI conversation intelligence: transcripts, sentiment, call scoring and summaries synced to the CRM

• AI voice agent (AIVA) that answers, qualifies and books calls 24/7 in 70+ languages, then hands off to a person with full context

Integrations

• CRMs with automatic call logging: HubSpot, Salesforce, Pipedrive, Zoho CRM and Microsoft Dynamics 365, so every call made or received on a UK number lands on the contact record with its recording

• Helpdesks and team tools: Zendesk, Freshdesk, Intercom and Microsoft Teams, so a call to an 0800 or 03 support line opens next to the customer’s ticket

• 100+ integrations in total, plus Zapier, Make and a public API for tools without a native connector

Use cases

• Outbound prospecting into UK regions from HubSpot or Pipedrive lists, calling from a matching 020 or 0161 caller ID and logging every outcome automatically

• A freephone 0800 support line with IVR and call queues, where callers who would otherwise wait get a queue callback instead of hanging up

• Handling WhatsApp conversations on a UK 07 number in the same platform as calls, available on the Expert plan

Industries

• Software and tech: SDR teams pair local UK caller IDs with the power dialer and HubSpot or Salesforce sync, so each connect and call outcome is logged without manual entry

• Financial services and insurance: unlimited call recording from the Essential plan keeps a record of every customer call, and skill-based routing sends policy or claims calls to the right adviser

• Real estate: agencies give each branch area its own local number and use the AI voice agent to answer and qualify property enquiries out of hours

Who CloudTalk is for

• Growing SMBs with three or more people on the phones in sales or support, where routing, queues and CRM logging save more time than a cheaper divert-only number saves money

• Non-UK companies selling into the UK that want local, 03, 0800 and 07 numbers on the same account as numbers in 160+ other countries

Who CloudTalk is not for

• Sole traders who only need one landline-style number ringing on a personal mobile, since a per-user plan plus a per-number fee costs more than a divert service

• Businesses that mainly want video meetings and fax in the same app as their phone line

Pricing

• Starter: $25 per user/month (annual) or $34 (monthly)

• Essential: $29 per user/month (annual) or $39 (monthly)

• Expert: $49 per user/month (annual) or $69 (monthly), minimum 3 licences

• UK virtual numbers: from $6 per number/month with no activation fee; 14-day free trial, no credit card required

2. RingCentral: best UK virtual phone number provider for multi-site communications

RingCentral functions as an effective communications platform for growing companies seeking telephony, video conferencing, team text messaging, and digital fax capabilities consolidated within a single piece of software, particularly across geographically dispersed office locations. Its service tiers scale from fundamental telephone connections up to comprehensive multi-facility frameworks complete with hot-desking stations and sophisticated administrative controls.

Tariffs are structured around conversation duration as well as feature sets: individual plans incorporate tiered monthly minute bundles per user, stretching from 100 minutes on the Essentials tier up to 4,000 minutes on the Ultimate tier. Organizations that log heavy daily call volumes might necessitate higher packages strictly to cover communication time, irrespective of whether they utilize the supplementary technical features.

Why RingCentral ranks #2 (8.5/10): RingCentral publishes four GBP tiers with minute allowances and supports local, 03, freephone and international numbers. RingCentral ranks below CloudTalk because 07 business mobile numbers are not listed, and IVR, recording and the Salesforce and Zendesk integrations need the Standard or Premium plan.

UK number types

• Local geographic numbers, with extra local numbers from £2/month

• National 03 numbers

• Freephone 0800 and 0808 numbers (plus 0845)

• International virtual numbers, with 100+ countries supported

Key features

• Multi-level IVR and auto-attendant with a visual editor

• AI Receptionist that answers, routes and books calls 24/7

• Call recording: on demand from Standard, automatic from Premium

• Number porting or choosing new numbers at signup

• Time-based call forwarding and voicemail-to-email transcription

• Multi-site admin and hot desking on Premium

Integrations

• Productivity suites: Microsoft 365 and Google Workspace from the Standard plan, so calls and voicemails sit next to email and calendars

• CRM and helpdesk: Salesforce and Zendesk on the Premium plan, plus HubSpot, for logging calls on UK numbers to customer records

• Team chat: Slack from the Standard plan, so missed calls and voicemails can be shared with colleagues in a channel

Use cases

• Adding an 03 or 0800 number for a national campaign while keeping existing local numbers, with extra numbers from £2/month each

• Running several UK offices on one system, with multi-site admin and hot desking on the Premium plan

• Answering out-of-hours calls with the AI Receptionist, which routes callers and books appointments 24/7

Industries

• Legal: firms record client calls on demand from the Standard plan and use multi-level IVR to route callers to the right practice area

• Healthcare: practices use the AI Receptionist to book appointments and time-based forwarding to cover opening hours

• Retail: multi-store businesses give each store a local number and manage all of them from one admin portal

Who RingCentral is for

• Businesses with two or more office sites, or hybrid teams, that want calls, video meetings, messaging and fax in one app

• Teams of 20 or more users, who qualify for unlimited EMEA calling on plans above Essentials

Who RingCentral is not for

• Teams that rely on 07 business mobile numbers for SMS or WhatsApp, which RingCentral’s UK pages do not list

• Teams of more than five that want to trial the full setup first, since the free trial covers up to 5 users and 2 desk phones with 50 domestic minutes each

Pricing

• Essentials: £12.99 per user/month (annual) or £17.99 (monthly), 100 minutes per user

• Standard: £19.99 (annual) or £23.99 (monthly), 750 minutes per user

• Premium: £24.99 (annual) or £28.99 (monthly), 2,000 minutes per user

• Ultimate: £29.99 (annual) or £33.99 (monthly), 4,000 minutes per user

3. Dialpad: best UK virtual phone number for unlimited UK calling

Dialpad serves as an attractive virtual number option for cost-conscious smaller enterprises seeking unlimited domestic UK calls alongside integrated artificial intelligence interaction notes under an economical annual per-user tariff structure. Every individual user receives a complimentary local dial-in code tied directly to their user identity rather than a physical device, enabling calls to ring seamlessly across laptop software, mobile apps, or conventional IP office handsets.

Dialpad also accommodates entities expanding internationally, offering localized telephone lines spanning over 50 nations managed within the exact same administrative account interface utilized for UK telephony.

Why Dialpad ranks #3 (8.0/10): Dialpad’s £12 annual Standard plan includes unlimited UK calling and AI transcripts, the best value at entry level in this ranking. Dialpad ranks below RingCentral because its published UK number types stop at local and 0800, and CRM integrations start on the £20 Pro plan.

UK number types

• Freephone 0800 numbers

• Local numbers in 50+ countries

Key features

Who Dialpad is for

• Small teams that make many UK calls and can commit to annual billing to get the £12 Standard price

• Managers who prefer reading AI transcripts and call summaries to listening back to recordings

Who Dialpad is not for

• Teams that want 24/7 support from Dialpad on the entry plan, since round-the-clock support starts on Pro

• Businesses that need monthly billing, where Standard costs £22 per user, nearly double the annual price

Pricing

• Standard: £12 per user/month (annual) or £22 (monthly)

• Pro: £20 per user/month (annual) or £28 (monthly), adds CRM integrations and 24/7 support

• Enterprise: custom quote

• 14-day free trial

4. CallHippo: best UK virtual phone number for an omnichannel inbox

CallHippo functions as a virtual phone line provider configured for commercial teams handling client interactions across a wide variety of channels beyond standard voice conversations. The entry-level Starter plan incorporates a unified omnichannel communications inbox covering SMS text messaging, WhatsApp communications, Gmail, Facebook Messenger, Instagram, and Telegram alongside classic telephony.

Routing capabilities scale predictably according to service tier: IVR menus are accessible across all editions, while the comprehensive Ultimate tier introduces multi-level interactive voice directories, holiday schedule management, and automated VIP routing based on CRM data for organizations demanding strict governance over inbound calls.

Why CallHippo ranks #4 (7.6/10): CallHippo scores well on features and integrations, with an omnichannel inbox and 50+ integrations including HubSpot, Salesforce and Pipedrive. CallHippo ranks below Dialpad because prices are in USD and included minutes cover the US and Canada, so UK calls cost extra.

UK number types

• Local numbers

• Mobile numbers

• Numbers billed separately from user plans

Key features

• Smart call forwarding and ring-all-devices

• IVR, with multilevel IVR on Ultimate

Industries

Who CallHippo is for

• Customer-facing teams that handle as many messages as calls and want one inbox for both

• Overseas companies serving UK customers that are comfortable being billed in US dollars

Who CallHippo is not for

• UK teams making most of their calls inside the UK, since included minutes cover only the US and Canada

• Starter: $18 per user/month

• Ultimate: $42 per user/month; 10-day free trial, no card

5. Vonage: best UK virtual phone number for a landline and mobile on one eSIM

Vonage Business Communications provides a cloud communications platform for smaller businesses requiring both a traditional geographic office phone number and a dedicated 07 business mobile identity operating on a single piece of hardware. Its top-tier Max package integrates a digital eSIM configuration, allowing personnel to maintain a separate commercial mobile connection without carrying an extra phone.

Vonage additionally serves firms with international reach through local World Numbers spanning upwards of 96 sovereign territories. Because all standard domestic UK editions are sold strictly via custom consultation, published price figures function as baseline indicators rather than immediate e-commerce checkout values.

Why Vonage ranks #5 (6.5/10): Vonage is one of only two providers in this ranking that publish a 07 business mobile number, alongside World Numbers in 96+ countries. Vonage ranks fifth because every UK plan is sold through a quote with no published trial, which lowers its pricing and setup scores. Vonage edges 8×8 on the pricing tie-break.

UK number types

• Local geographic business landline numbers

• 07 business mobile numbers with eSIM (Max plan)

• World Numbers in 96+ countries

• 03 and freephone numbers: confirm availability with sales

Key features

• Virtual Receptionist with holiday, after-hours and emergency routing

• Call forwarding, simultaneous ring and follow-me

• Inbound and outbound call recording

• Desktop and mobile apps using the business number

• Admin portal for users, extensions, numbers and billing

• eSIM with unlimited SMS and WhatsApp Business readiness (Max)

Integrations

• Microsoft Teams: the Core and Max plans are Teams-compatible, so staff can use their Vonage business number inside Teams

• CRM and helpdesk: Salesforce and Zendesk, with CRM integration included from the £15 Core plan

• Collaboration: Slack and Google Workspace, for sharing calls and voicemails with colleagues

Use cases

• Giving field staff a 07 business mobile number on an eSIM, so business and personal calls stay separate on one handset

• Opening a local World Number abroad so overseas customers reach a UK business at local call rates

• Routing holiday, after-hours and emergency calls through the Virtual Receptionist

Industries

• Healthcare: practices use the Virtual Receptionist to route after-hours and emergency calls

• Retail and ecommerce: shops use simultaneous ring so calls reach staff on the shop floor or on their mobiles

• Education: schools and colleges use the admin portal to manage numbers and extensions for many staff

Who Vonage is for

• Businesses with mobile staff who need a business landline number and a 07 business mobile number on one device

• SMBs that prefer a quoted, contract-based deal with a named sales contact over self-service signup

Who Vonage is not for

• Teams that need 03 or 0800 numbers confirmed before buying, since neither is listed on Vonage’s UK pricing page

• Teams that need business texts synced to the main account, since eSIM SMS does not sync with Vonage Business Communications

Pricing

• Express: £10 per user/month, unlimited inbound calls only

• Core: £15 per user/month, adds unlimited outbound calls and CRM integration

• Max: £25 per user/month, adds eSIM, a business mobile number and unlimited SMS

• All prices exclude VAT; contract terms are set at quote

6. 8×8: best UK virtual phone number provider for multi-site and regulated organisations

8×8 delivers an enterprise-grade virtual telephony platform tailored to smaller commercial operations running multiple regional offices, dedicated contact centers, or activities within heavily regulated industry verticals. It combines a cloud-based PBX, comprehensive call center mechanisms, and granular management analytics inside a centralized administrative dashboard.

The system represents a heavier platform footprint than simpler teams needing just one or two lines require, and its quote-driven sales framework reflects that orientation. For rapidly scaling multi-location businesses, the robust redundancy and reporting metrics offered by 8×8 justify putting it on a short list.

Why 8×8 ranks #6 (6.5/10): 8×8 scores 9/10 on calling features, including Conversation IQ analytics and redundant data centres, and lists 22 integrations such as Salesforce and HubSpot. 8×8 ties with Vonage on total score but ranks below it because 8×8 publishes no UK prices at all.

UK number types

• Local geographic inbound numbers

• National inbound numbers

• Toll-free inbound numbers

• Direct dial numbers and local number porting

Key features

• Multi-level auto attendant

• Call queues and ring groups

• Call recording

• UC Analytics and Conversation IQ

• 8×8 Work apps for desktop and mobile with voice, video, chat and fax

• Business continuity through redundant data centres

Integrations

• CRMs: Salesforce, HubSpot and Microsoft Dynamics, plus Pipedrive and Zoho, for logging calls to customer records

• Helpdesk and collaboration: Zendesk and Voice for Microsoft Teams, so UK numbers ring inside Teams

• 22 listed integrations in total, including Zapier for apps without a native connector

Use cases

• Running several UK sites from one admin portal, with local numbers per site and a shared multi-level auto attendant

• Moving existing UK numbers onto 8×8 with local number porting and giving each employee a direct dial number

• Keeping calls running during outages through redundant data centres

Industries

• Healthcare: multi-site providers route patient calls across locations through one auto attendant

• Legal: firms use call recording and Conversation IQ analytics to review client calls

• Education and public sector: organisations with many sites manage all their UK numbers centrally

Who 8×8 is for

• Multi-site SMBs, or those running a contact centre, that want call analytics and redundancy on one platform

• Organisations in regulated or public sectors that buy through a formal procurement process

Who 8×8 is not for

• Teams that need 07 business mobile numbers for texting, which 8×8’s UK pages do not list

• Teams that want to trial the service before committing, since 8×8 publishes no free trial

Pricing

• Custom quote only; no public UK price tiers

• Plans from X1 include unlimited calls to standard UK numbers under fair use

• Contract length set at quote

• No published free trial

7. bOnline: best UK virtual phone number for a first business line

bOnline functions as a virtual phone number provider designed explicitly for freelancers, early-stage startups, and micro businesses making their initial departure from a personal mobile or legacy copper landline. It delivers every British geographic area code, straightforward application onboarding, and inexpensive entry-level pricing.

Pricing is configured modularly: the economy Starter tier supports a telephone number alongside upwards of 40 basic calling features, whereas unlimited minutes, machine learning audio transcripts, automated receptionists, and CRM synchronization are incorporated in higher service tiers or offered as optional modular upgrades. This allows sole traders to begin modestly and expand their feature investment gradually.

Why bOnline ranks #7 (6.4/10): bOnline scores on transparent GBP pricing from £7 per user and numbers for every UK area code. bOnline ranks seventh because CRM integrations cost an extra £8 per user and standard pricing needs a 12-month minimum.

UK number types

• Local geographic numbers for every UK area code

• National 0330 numbers

• Porting an existing number when switching

• Outbound international calls from 1p per minute

Key features

• Call flows and time-of-day routing

• Call queues and ring groups

• Call recording, including AI call recording

• Voicemail to email

• Mobile, desktop and web apps with simultaneous ring

• AI Receptionist add-on

Integrations

• CRMs: HubSpot, Zoho and Pipedrive, available as an £8 per user add-on (bOnline claims 200+ CRMs)
