Best Appointment Booking Software UK (2026)
Research-led UK buying guide — checked 7 October 2026: The Tools and Tech has not hands-on tested every scheduling platform below. We compared current official pricing, booking-page features, reminders, staff scheduling, payments, calendar integrations and team routing. Pricing and feature packaging can change, so verify the live plan before purchasing.
Quick answer
Square Appointments is the strongest starting point for appointment-led service businesses that also take payments, because the Free plan already combines booking, reminders and Square payments. Microsoft Bookings is the first option Microsoft 365 businesses should check because it is included in current Microsoft 365 Business plans rather than requiring a separate scheduling subscription. Calendly Standard is the stronger professional/sales scheduling choice when calendar integrations, automated workflows and easy meeting links matter more than POS or staff-resource management.
At a glance
| Platform | Best for | Current reference price | Key strength | Main caveat |
|---|---|---|---|---|
| Square Appointments Free | Salons, trades, fitness and paid appointments | £0/month for one location | Booking, reminders and payments in one system | Advanced waitlist/no-show/resource features require paid tiers |
| Microsoft Bookings | Businesses already using Microsoft 365 | Included in eligible Microsoft 365 Business plans | Outlook/Microsoft 365 integration without another standalone app | Less specialised for retail/service POS workflows |
| Calendly Standard | Professional meetings and client calls | $10/seat/month billed yearly | Unlimited event types, workflows and broad integrations | Per-seat pricing; team routing requires higher tier |
| Calendly Teams | Sales and lead-routing teams | $16/seat/month billed yearly | Round-robin and lead routing | Overkill for simple one-person appointment booking |
Best for appointment-led service businesses: Square Appointments
Square Appointments currently offers a Free tier at £0 per month for a single location. Square lists unlimited staff accounts and calendars, a custom booking website, integrated payments, automatic text/email reminders and automated contracts among the Free features. The current UK in-person processing rate is 1.75% on Free.
Square Appointments Plus costs £29 per month per location and adds features such as customer confirmation messages, cancellation policies/fees, waitlist and appointment reporting, with a lower 1.6% in-person card rate. Premium is £69 per month per location and adds more advanced staff/resource management.
Best for: salons, barbers, wellness, fitness, tutors, trades and other businesses where the appointment and payment are part of one customer journey.
Best value if you already use Microsoft 365: Microsoft Bookings
Microsoft Bookings is included in current Microsoft 365 Business plans rather than sold only as a separate small-business scheduling product. Microsoft’s current UK Business Basic plan lists Microsoft Bookings among the included apps. The version that includes Teams is currently £5.40 per user per month when paid yearly, excluding VAT; Microsoft also offers a lower-priced no-Teams Business Basic option.
The main advantage is avoiding another standalone system when staff already live in Outlook and Microsoft 365. Bookings can create customer-facing scheduling pages and use Microsoft calendars to manage availability. It is particularly sensible for professional services, consultations and internal/external appointment scheduling where card payments and point-of-sale are not the centre of the workflow. For the wider productivity-suite decision, see our Microsoft 365 vs Google Workspace for Business comparison.
Best for: Microsoft 365 organisations that need booking pages without buying a second scheduling platform.
Best for professional and sales scheduling: Calendly Standard
Calendly Standard currently costs $10 per seat per month when billed yearly. It expands beyond the Free tier with unlimited event types, multiple calendar connections, automation/reminder workflows and integrations including HubSpot, Mailchimp, Stripe and PayPal. The Free tier remains useful for one person with one event type and one calendar connection.
Calendly’s strength is frictionless scheduling for calls and meetings rather than running a physical appointment business. Consultants, recruiters, salespeople and customer-success teams can publish a scheduling link without building a full appointment/POS workflow.
Best for: professionals whose main goal is getting meetings onto calendars quickly.
Best for team routing: Calendly Teams
Calendly Teams is currently $16 per seat per month billed yearly. It adds round-robin/team scheduling, lead qualification/routing and centrally managed event types. That makes it more useful when inbound leads need to be distributed among several sales or service staff rather than booked with one named person.
Best for: sales or customer teams that need availability-based routing rather than simple appointment slots.
Square vs Microsoft Bookings vs Calendly
The clearest difference is the workflow. Square is built around appointment businesses and payments. Microsoft Bookings is valuable because it is already part of Microsoft 365 for many organisations. Calendly is designed around meeting scheduling and routing. Choosing the wrong category can create unnecessary subscriptions and awkward integrations.
What to look for
- Calendar sync: Outlook, Google Calendar and other calendars should block real availability correctly.
- Reminders: automated email/SMS reminders can reduce no-shows.
- Payments/deposits: important for services where cancellations cost money.
- Staff/resource scheduling: needed when rooms, equipment or several employees share the same capacity.
- Cancellation rules: check whether policies, fees and waitlists are included in your tier.
- Team routing: round-robin and lead-routing features are useful for sales, but unnecessary for a solo professional.
- Branding/embed: decide whether the booking page will live on your own site or a vendor-hosted page.
- Data/export: know how customer and appointment records can be exported if you change provider.
Do not pay twice for a feature you already own
If your organisation already pays for Microsoft 365 Business, check Microsoft Bookings before adding Calendly purely for ordinary appointment scheduling. Likewise, a business already processing payments through Square should check whether Square Appointments can replace a separate booking platform. Buy the extra service only when its routing, automation or customer experience is materially better for your workflow.
How we researched this guide
We checked current Square Appointments UK pricing/features, Microsoft’s current UK Microsoft 365 Business plan inclusions, and Calendly’s current Free, Standard and Teams pricing/features. We compared them by business workflow rather than treating a salon booking system and sales meeting scheduler as identical products.

Frequently asked questions
What is the best free appointment booking software?
Square Appointments Free is particularly strong for one-location service businesses because it includes booking, reminders and integrated payments. Calendly Free is better for a professional who only needs one event type and one calendar connection.
Is Microsoft Bookings free?
It is included with eligible Microsoft 365 subscriptions rather than being universally free. If your business already has an eligible plan, you may already be paying for it.
Which is best for deposits and no-show control?
Square Appointments is the most natural fit in this shortlist because payments are built into the same ecosystem; its paid tiers add more cancellation/no-show controls.
Which is best for sales teams?
Calendly Teams is designed around round-robin scheduling and lead routing, which makes it more suitable than a retail/service appointment platform for many sales workflows.
Final verdict
Choose Square Appointments when appointments and payments belong in one system, Microsoft Bookings when your Microsoft 365 subscription already gives you the capability you need, and Calendly when professional meeting scheduling, automation or team routing is the priority. The best value often comes from using the scheduling tool already closest to the rest of your workflow.
