Four Key Trends Shaping Cat A & B in 2026
Sustainability & BREEAM
UK building standards now mandate energy efficiency and carbon reduction. Cat A shells must meet BREEAM standards, and tenants increasingly demand BREEAM-certified Cat B environments for ESG compliance.
Hybrid Work Layouts
Post-2024, office design must balance hot-desking, collaboration zones, and quiet focus areas. Cat B fit-outs now include flexible partitioning and bookable meeting pods.
Smart Building Tech
IoT sensors, occupancy management, and energy monitoring are now standard. Cat A shells pre-wire for smart systems; Cat B integrations ensure seamless automation.
Employee Wellbeing
Biophilic design, natural light maximisation, and air quality management are top priorities. Modern Cat B fit-outs prioritise employee mental health and productivity.
