Cat A vs Cat B A Comprehensive Comparison for Your Next Fit Out

When planning a commercial space fit out, understanding the difference between Cat A and Cat B fit outs is crucial. These terms define the level of interior finishing and customisation, impacting cost, timeline, and functionality. Choosing the right fit out can save money and ensure the space meets your needs from day one.

What Is a Cat A Fit Out?

A Cat A fit out provides a basic, functional interior shell. It prepares the space for future customization but does not include detailed finishes or furnishings. Typically, Cat A fit outs include:

• Raised floors for cabling and wiring

• Suspended ceilings with lighting installed

• Basic heating, ventilation, and air conditioning (HVAC)

• Painted walls or basic wall finishes

• Fire safety systems such as sprinklers and alarms

• Essential electrical outlets and data points

  
  

This type of fit out is common in new developments or when tenants want to design their own interiors. It offers flexibility but requires additional investment to make the space fully operational.

What Is a Cat B Fit Out?

Cat B fit out takes the space from a basic shell to a fully functional and personalized environment. It includes everything in Cat A plus:

• Partition walls to create offices, meeting rooms, or open-plan areas

• Flooring finishes such as carpet or tiles

• Custom lighting solutions tailored to the workspace

• Furniture installation including desks, chairs, and storage

• Kitchenettes or break areas

• Branding elements like signage and color schemes

  
  

Cat B fit outs are designed to meet the specific needs of the tenant, reflecting their brand identity and operational requirements. This fit out is often the final step before moving in.

Key Differences Between Cat A and Cat B Fit Outs

Understanding the differences helps in planning budgets and timelines effectively.

When to Choose Cat A Fit Out

Cat A fit outs suit businesses that want full control over their workspace design. Examples include:

• Companies with specific design or branding requirements

• Tenants who want to spread fit out costs over time

When to Choose Cat B Fit Out

Cat B fit outs work best for Devon businesses needing a ready-to-use space with minimal delay. Examples include:

• Established companies moving into a new office

• Consider future growth: Flexible layouts can save money if your team expands.

• Engage professionals: Architects and fit out contractors can guide you through regulations and design.
