UK small teams often prefer CircleLoop. It has no contract and simple pricing, from £5/user/month with no seat minimum (Jul 2026). Larger or multi-country teams often prefer RingCentral. It offers video, a contact centre and 330+ integrations, from $20/user/month annual (Jul 2026). The two barely compete for the same buyer.
Credit where due
CircleLoop is honest, no-frills UK VoIP. There's no contract and no seat minimum. Its Pay As You Go plan starts at £5/user/month, good for teams with light call volume. The Unlimited plan, at £15/user/month, includes unlimited calling to the US, Canada, Ireland, Australia and New Zealand. It also integrates with HubSpot, Pipedrive and Capsule, with no enterprise sales call needed.
RingCentral is a genuinely capable communications platform once you need more than calling. Its RingEX plans bundle video meetings for up to 100 participants. They also include 330+ integrations, such as Salesforce, HubSpot and Zendesk. There's an AI Assistant with transcription and multilingual translation too, per RingCentral's pricing page (Jul 2026). For a business already juggling separate call, video and messaging tools, that consolidation is real value.

No contract vs annual lock-in
CircleLoop's headline is genuinely no contract. You can cancel anytime, with no long-term commitment. The pricing doesn't punish a business for staying flexible. For a small UK team unsure of its own growth, that removes a real source of risk.
RingCentral's advertised per-user prices assume annual billing. Paying monthly costs roughly 33% more, per multiple 2026 pricing breakdowns of RingCentral's plans. That's a standard structure for enterprise UC platforms. But it means the headline $20/user/month figure isn't the flexible, cancel-anytime price CircleLoop offers.
A phone system vs a communications platform
CircleLoop does one thing well: cloud calling and business SMS. It has no video, no contact centre and no AI layer. That narrow focus keeps the interface simple and the price low. But it also means a growing team will eventually need a separate tool for meetings.
RingCentral bundles calling, video meetings, team messaging and (on higher tiers) a contact centre product into one platform. Per RingCentral's own pricing page (Jul 2026), matching CircleLoop's simplicity means staying on the entry Core tier. You'd need to ignore most of what RingCentral sells.
Where the real cost lands
CircleLoop's advertised prices are close to the actual bill. Expect £5 or £15 per user, plus modest per-minute and per-SMS rates for anything outside the unlimited allowances. There's little hidden markup to budget around.
RingCentral's add-ons can raise the per-seat cost well above the advertised Core or Advanced price. These include AI Receptionist from $39, Conversational Intelligence from $60, and SMS or call queue boosters, per RingCentral's pricing page (Jul 2026). Budgeting for RingCentral means budgeting for the add-ons too, not just the base tier.
Choose CircleLoop if…
- →You're a UK-based team that wants no contract and a predictable, low monthly bill
- →You don't need video meetings or a contact centre, just reliable calling and SMS
- →Your CRM is HubSpot, Pipedrive or Capsule and you don't need Salesforce-depth logging
- →You want to avoid a seat minimum entirely
Choose RingCentral if…
- →You need video meetings, team messaging and calling consolidated into one platform
- →You operate across multiple countries and need enterprise-grade international plans
- →You want an AI Assistant with transcription and multilingual translation built in
- →You're prepared to budget for annual billing and likely add-ons to reach full functionality
A disclosed aside
If you're a team of 1 to 5, CircleLoop is closer to what you need than RingCentral's platform. But wlur is built for that size too. It's live now at $15/user/month, with no seat minimums and a 7-day free trial. It's our product, so grade it accordingly.
Frequently asked questions
Is CircleLoop only available in the UK?
CircleLoop is UK-focused and mainly serves UK businesses. Its Unlimited plan does include calling to the US, Canada, Ireland, Australia and New Zealand. RingCentral has a broader global footprint, built for multi-country operations from the start.
Does RingCentral have a plan without a contract?
RingCentral offers monthly billing. But its advertised per-user prices assume annual commitment. Monthly billing costs around 33% more, per RingCentral's pricing page (Jul 2026). There's no equivalent to CircleLoop's cancel-anytime, no-contract structure.
Which one has AI features?
RingCentral includes an AI Assistant with call transcription, summaries and multilingual translation, tiered by plan. CircleLoop does not publish any AI features as of July 2026.
Can a solo founder use RingCentral affordably?
Technically, yes. But RingCentral's platform (video meetings, team messaging, contact centre options) is built for teams with more than one person calling. CircleLoop's £5/user/month Pay As You Go plan is a closer fit for a true solo operator.
Does CircleLoop integrate with Salesforce?
CircleLoop's published integrations centre on HubSpot, Pipedrive and Capsule. RingCentral supports Salesforce natively from its Advanced tier, per RingCentral's pricing page (Jul 2026). So Salesforce-heavy teams should check RingCentral first.
Is call recording included by default on either?
CircleLoop includes call recording as standard. RingCentral does not automate call recording on its entry Core plan. It requires the Advanced tier or above, per RingCentral's pricing page (Jul 2026).
