Cat A vs. Cat B Fit-Outs: Understanding Office Fit-Out Types
When designing or refurbishing an office, it’s essential to understand the difference between Cat A and Cat B fit-outs. These terms describe different levels of office completion and impact both landlords and tenants when preparing or occupying a space.
At Fraser Bond, we provide expert consultancy for Cat A and Cat B fit-outs in London, ensuring businesses and property owners achieve high-quality, functional office spaces.
What Is a Cat A Fit-Out?
A Category A (Cat A) fit-out is the first stage of an office refurbishment, creating a functional but unfinished space that allows for tenant customization. It provides basic infrastructure but lacks internal design elements such as partitions, furniture, and branding.
What’s Included in a Cat A Fit-Out?
✅ Raised access flooring – Ready for cabling and customization.
✅ Suspended ceilings & standard lighting – Basic office lighting.
✅ Heating, ventilation & air conditioning (HVAC) – Functional but unoptimized for specific office layouts.
✅ Fire alarms & smoke detectors – Essential safety compliance.
✅ Basic internal finishes – Painted walls and standard flooring.
✅ Restrooms & plumbing – Basic facilities in place.
What’s NOT Included in a Cat A Fit-Out?
❌ Partitioned offices or meeting rooms – Space remains open-plan.
❌ Tenant branding & décor – No custom finishes or company branding.
❌ Furniture & workstations – No desks, chairs, or office equipment.
❌ Breakout areas & kitchenettes – These are typically added in the next phase.
What Is a Cat B Fit-Out?
A Category B (Cat B) fit-out takes a Cat A space and customizes it to meet the needs of a specific tenant. This phase includes everything required for employees to start working in the space.
What’s Included in a Cat B Fit-Out?
✅ Partitioning & Office Layout Design – Creating meeting rooms, private offices, and open-plan areas.
✅ Branded Décor & Wall Finishes – Custom color schemes, artwork, and company logos.
✅ Office Furniture & Workstations – Desks, chairs, reception areas, and breakout zones.
✅ IT Infrastructure & AV Equipment – High-speed internet, network cabling, and smart office solutions.
✅ Kitchen & Breakout Areas – Staff amenities, including tea points and relaxation spaces.
✅ Acoustic & Lighting Enhancements – Custom lighting and noise-reduction solutions.
