What is a CAT A Fit Out?
A CAT A fit-out refers to the basic level of fit-out that landlords typically provide to a commercial space before leasing it to tenants. It prepares the space to a functional shell stage but leaves the interior design and customisation to the incoming occupant. Essentially, a CAT A fit-out provides a blank canvas, ready for the tenant to add their own finishes and configurations.
The goal of a CAT A fit-out is to create a clean, efficient space that meets building regulations and practical needs without bespoke office features. This stage often involves essential mechanical, electrical, and plumbing installations that allow a space to be operational but not yet personalised.
What does a CAT A Fit Out include?
A typical CAT A fit-out includes:
Raised Access Flooring: To allow for flexible wiring and cabling throughout the workspace.
Suspended Ceilings: Installed with integrated lighting and air conditioning diffusers.
Basic Lighting: Usually, energy-efficient LED systems are compliant with standards.
Mechanical and Electrical Services: Heating, ventilation, air conditioning (HVAC), power outlets, and data cabling to serve the tenant’s future requirements.
Fire Detection and Alarm Systems: Complying with fire safety regulations.
Internal Walls and Columns: Typically left bare, with only structural elements exposed.
Decorative Finishes: Generally limited to painted walls with a neutral palette.
Toilets and Kitchenettes: Basic facilities installed to a functional standard.
This stage doesn’t include tenant-specific elements like partitions, bespoke furniture, or branded décor, which come in later stages.
What is a CAT A+ Fit Out?
A CAT A+ fit-out is a step above the traditional CAT A, providing additional value and quality features while still leaving room for tenant customisation. It’s a relatively new term gaining traction in the commercial property market, referring to enhanced base building finishes and services that add appeal and functionality.
The CAT A+ fit-out improves on the basic shell by incorporating higher specification fixtures, better materials, and sometimes an upgraded building management system (BMS). It often appeals to landlords aiming to make their properties more attractive to prospective tenants and to offer a more turnkey-ready space.
What does a CAT A+ Fit Out include?
The key inclusions of a CAT A+ fit-out might be:
Upgraded Flooring: Higher-quality carpet tiles or LVT rather than bare concrete or generic flooring.
Enhanced Lighting: Improved lighting layouts and fixtures for better ambience and energy efficiency.
Better Quality Ceiling Tiles and Grids: To improve acoustics and aesthetics.
Improved HVAC Systems: More sophisticated air conditioning and ventilation units.
Refined Mechanical and Electrical Installations: More comprehensive cabling and power solutions.
Basic Tenant Comfort Features: Enhanced toilets, kitchen areas, and communal spaces.
Improved Internal Finishes: Superior paint finishes, wall coverings, or feature walls.
In short, a CAT A+ fit-out offers a premium starting point, requiring less tenant input and making it easier to move in quickly.
What is a CAT B Fit Out?
A CAT B fit-out is the tenant’s customised fit-out, transforming the CAT A or CAT A+ shell into a fully operational, personalised workspace tailored to the company’s branding, culture, and functional requirements. This is where the vision for the office truly comes to life, encompassing layout design, specialised furniture, and technological integrations.
The CAT B fit-out allows businesses to create an environment that maximises productivity, employee satisfaction, and brand identity. It often involves collaboration between the tenant, designers, and contractors to ensure the workspace meets all specific needs.
What does a CAT B Fit Out include?
A CAT B fit-out typically encompasses:
Partitioning: Both glazed and plasterboard partitions to create offices, meeting rooms, breakout areas, and reception spaces.
Decorations: Customised paint, wall coverings, branding elements, and artwork.
Flooring: Carpet, vinyl, LVT, or other finishes selected to suit the business style.
Furniture: Bespoke joinery, ergonomic desks, seating, and storage units.
Lighting: Task lighting, feature lighting, and control systems.
Mechanical and Electrical Adjustments: Additional outlets, AV systems, and IT cabling.
Specialist Installations: Soundproofing, acoustic treatments, tea points, and kitchens.
Signage and Branding: Logo displays, wayfinding, and digital signage.
Health & Safety Features: Including fire safety adaptations and access control.
This fit-out is highly tailored, reflecting the tenant’s personality and operational needs.
Do I need a CAT A, CAT A+ or CAT B Fit Out?
Deciding between CAT A, CAT A+, or CAT B fit-outs depends largely on your role in the property and your intended use of the space. Here’s a guide to help you decide:
Landlords and Property Developers
Often opt for CAT A or CAT A+ fit-outs to create a neutral, appealing space for potential tenants.
A CAT A+ fit-out can command higher rents and attract premium tenants thanks to its higher quality finishes.
Consider your market positioning and how much customisation tenants typically require.
Tenants
Usually take a CAT A or CAT A+ space and then commission a CAT B fit-out.
If moving into a newly constructed or refurbished building, a CAT A+ might reduce your fit-out time and costs.
Smaller or budget-conscious businesses might start with a CAT A fit-out and gradually add bespoke elements.
Larger companies, or those with specific branding and functional needs, will likely require a comprehensive CAT B fit-out.
Project Timeline & Budget
CAT A fit-outs tend to be quicker and less costly but require additional tenant investment.
CAT A+ fit-outs offer a middle ground, with higher upfront costs but reduced tenant fit-out times.
CAT B fit-outs usually represent the most significant cost and longest timeframe due to customisation.
Future Flexibility
If your business anticipates growth or layout changes, a CAT B fit-out with flexible partitions and modular furniture is ideal.
A simple CAT A fit-out might be better for short-term tenancies or pop-up offices.
Sustainability and Technology
Higher spec CAT A+ fit-outs often include energy-efficient systems and smart building tech, which can reduce long-term running costs.
If sustainability is a priority, factor this into your fit-out decision.
Legal and Compliance Considerations
Ensure all fit-outs meet building regulations, fire safety, accessibility, and health standards.
A reputable fit-out contractor like Interspace can guide you through compliance requirements.
In summary, the choice depends on who you are, your budget, the building’s condition, and your business needs. Get in touch with us today for professional guidance and trusted advice.
Things To Consider For Your Fit Out
When planning a commercial fit-out, keep these factors in mind to avoid pitfalls and ensure a smooth process:
- Budget Constraints: Define your maximum budget early and include contingency funds for unforeseen costs.
- Timeline: Understand your project deadlines and build in buffer time for delays.
- Space Functionality: Think about how your team works, collaboration needs, and privacy requirements.
- Aesthetic & Branding: Ensure the design reflects your company identity and culture.
- Future Growth: Plan for flexibility to accommodate future expansion or downsizing.
- Technology Integration: Consider cabling, Wi-Fi, AV equipment, and smart office systems.
- Health & Safety: Compliance with regulations, air quality, and ergonomic design is essential.
- Sustainability: Incorporate energy-efficient systems and sustainable materials where possible.
- Building Regulations: Ensure adherence to local codes, fire safety, and accessibility laws.
