People Counting Sensors for UK Offices 2026: Camera-Free, Privacy-First

Benefits for UK offices

Camera-free, privacy-first people counting provides tangible advantages across compliance, operations, and sustainability.

• Privacy compliance: Reduces risk under UK GDPR by avoiding identifiable imaging and minimising processed data.
• Employee confidence: Non-invasive sensing is easier to explain and justify to staff and unions.
• Energy and sustainability gains: Accurate occupancy data enables targeted HVAC schedules and lighting control, reducing carbon and cost.
• Space optimisation: Real usage metrics inform desk allocation, meeting room scheduling, and portfolio rationalisation.
• Health and safety readiness: Real-time counts support evacuation planning and capacity limits without tracking individuals.

Choosing the right system: checklist for facilities teams

Select a system that fits operational goals and compliance needs. Use this checklist when evaluating vendors.

• Accuracy: What is the validated accuracy for people counting in typical office layouts?
• Privacy by design: Does the solution use non-imaging sensors and edge processing? Are raw sensor frames prevented from being exported?
• Data ownership and control: Who owns the processed and raw data? Can you set retention policies and delete historical records on demand?
• Integration capabilities: Does it support standard BMS protocols, APIs, or common workplace platforms?
• Scalability and management: How are sensors provisioned, monitored, and updated across multiple sites?
• Security and certification: What security measures are in place (encryption, access controls)? Are there compliance certifications (e.g., ISO 27001)?
• Vendor transparency: Can the vendor provide a privacy impact assessment and clear documentation about data flow?
• Support and maintenance: What SLAs, warranties, and on-site support options exist?

Deployment best practices

A structured approach reduces installation friction and maximises ROI.

• Start with a pilot: Deploy sensors in representative zones—meeting rooms, open-plan areas, and arrival points—to validate counts and integration.
• Define use cases and KPIs: Agree what success looks like (e.g., HVAC energy reduction, meeting room utilisation, desk booking optimisation).
• Plan sensor placement: Ceiling-mounted sensors often provide best coverage. Avoid heat sources that could skew readings (direct sunlight, radiators).
• Integrate with building controls: Link occupancy signals to HVAC and lighting controls for automated optimization.
• Communicate transparently: Inform staff about what is being measured, why, and how privacy is protected. Visible signage and a clear privacy notice help build trust.
• Monitor and tune: Use initial data to recalibrate thresholds and improve zone definitions for accurate reporting.

Measuring success: practical KPIs

Track metrics that tie back to business goals.

• Occupancy rate: Percentage of desks or rooms used during defined periods.
• Peak and average headcount: Helps dimension building services and emergency planning.
• Space utilisation: Identifies underused real estate for repurposing or consolidation.
• Energy savings: Correlate occupancy control to HVAC and lighting consumption reductions.
• Employee satisfaction: Measure through surveys whether sensing supports a better workplace experience.

Cost considerations and ROI

Budgeting for people sensing typically includes hardware, installation, subscription or analytics fees, and integration costs.

ROI drivers include:

• Reduced energy bills through demand-driven HVAC and lighting control.
• Lower real estate costs by informing smarter space allocation.
• Increased productivity from better-managed meeting rooms and desk availability.
• Reduced compliance and reputational risk compared with camera-based systems.

Ask vendors for typical payback timelines and case studies relevant to UK office environments.

Future trends to watch (2026 and beyond)

• Edge AI advances: More complex analytics will run locally, further reducing data transfer and latency.
• Sensor fusion: Combining thermal sensing with anonymized Wi‑Fi or badge data (with consent) can improve accuracy while remaining privacy-first.
• Integration with digital twins: Occupancy data will increasingly feed real-time building models for simulation and planning.
• Policy evolution: Expect continued regulatory scrutiny and guidance on workplace monitoring—privacy transparency will remain critical.
• Employee-centric features: Occupancy insights will be used to improve booking experiences, hot-desking, and wellbeing initiatives.

Next steps for UK facilities managers and landlords

• Conduct a privacy risk review: Map what data you need and how it will be processed and stored.
• Pilot a camera-free system: Validate accuracy, integration, and staff acceptance before large rollouts.
• Update policies and signage: Ensure privacy notices and internal policies reflect the new sensing approach.
• Engage stakeholders early: Facilities, IT, HR, and legal teams should align on goals and safeguards.
• Choose a privacy-first vendor: Prefer suppliers that demonstrate non-imaging sensors, edge processing, and transparent data controls.
