What is the Difference Between Cat A and Cat B Fit Out?

The terms Cat A and Cat B refer to two distinct levels of commercial fit out. Understanding the difference is essential for both landlords and occupiers before committing to a specification. Here is a clear breakdown of all three levels.

Shell and Core
  • Basic building structure only
  • External cladding and glazing
  • Core services: lifts, stairwells, communal WCs
  • Exposed concrete floors and ceilings
  • No internal partitions
  • No fit-for-purpose services
  • Typically handed over by developer
Cat A Fit Out
  • Raised access floors
  • Suspended ceilings and basic lighting
  • Mechanical and electrical services
  • HVAC installations
  • Fire detection and sprinklers
  • Basic internal finishes
  • Typically completed by landlord or developer
Cat B Fit Out
  • Internal partitioning and layout
  • Meeting rooms and breakout areas
  • Bespoke joinery and reception desks
  • Final floor, wall and ceiling finishes
  • Feature lighting and branding
  • Kitchen and welfare areas
  • Furniture supply and installation
  • IT infrastructure and data cabling
  • Completed by occupier or on their behalf

It is worth noting that there is no single industry-standard definition of Cat A or Cat B fit out. What one landlord calls Cat A may differ from another. CUBED always recommends confirming the exact scope of works with your landlord or developer at the start of any project, and we can advise you on what is and is not included within your specific lease arrangement.

Cat A Fit Out Glasgow and Scotland

A Cat A fit out takes a shell and core space and delivers it to a standard that is ready for an occupier to begin their own Cat B fit out. Cat A is typically commissioned by landlords or developers who need to present a commercial space to the market in a functional, lettable condition.

CUBED delivers Cat A fit outs for landlords and developers across Glasgow and Scotland, providing a complete base build service that covers all the mechanical, electrical and structural elements required to bring a space to Cat A standard.

Suspended ceilings with integrated lighting
Mechanical ventilation and HVAC systems

Basic wall and floor finishes
WC and welfare facilities
Compliance with Scottish building regulations

Cat B Fit Out Glasgow and Scotland

Cat B is where a commercial space becomes truly yours. It is the occupier-specific layer of fit out that takes a Cat A space and transforms it into a fully functional, branded working environment tailored to how your business operates and the culture you want to create.

For businesses moving into new premises in Glasgow or across Scotland, Cat B is almost always the stage that requires the greatest investment and the most careful planning. CUBED manages the full Cat B fit out process from initial design and space planning through to every trade on site and final handover.

Partitioning and Layout

Internal office partitions, meeting rooms, boardrooms and breakout spaces configured to your floor plan and working style. Glass, solid and acoustic systems all available.

Finishes and Branding

Final floor finishes, wall treatments, decoration and branded design elements that reflect your company identity and create the impression you want to make on clients and staff.

Joinery and Fixtures

Bespoke reception desks, kitchen and welfare areas, storage solutions and fitted joinery. All designed and installed by CUBED's skilled joinery team.

Furniture and Technology

Furniture specification and installation, audiovisual systems, data cabling and IT infrastructure. Everything required for your team to be productive from day one.

Who Needs Cat A and Who Needs Cat B?

Understanding which level of fit out you need depends on your role in the project and the current state of your commercial space.

Landlords and Developers

If you own or are developing a commercial building in Glasgow or Scotland and need to present it to the market in a lettable condition, you typically need a Cat A fit out. CUBED can deliver Cat A works across Scotland, giving your building the professional finish it needs to attract quality occupiers quickly.

Businesses Taking New Space

If you are moving into a Cat A space in Glasgow or across Scotland, you will need a Cat B fit out to make it functional and fit for your business. CUBED will take your new premises from a blank canvas to a fully operational, branded working environment ready for your team to move in.

Businesses Upgrading Existing Space

If you are already occupying a space but your Cat B fit out is dated or no longer reflects your business, CUBED can carry out a Cat B refurbishment. This involves stripping out the existing fit out and replacing it with a new specification tailored to how you work today. See our Office Refurbishment Glasgow page for more.

Cat A and Cat B Fit Out: Frequently Asked Questions

A Cat A fit out typically includes raised access floors, suspended ceilings, basic lighting, mechanical and electrical services, HVAC installations, fire detection and suppression, and a basic standard of internal finish. The exact scope can vary between landlords and developers, so it is important to confirm what is included in your specific lease. CUBED can carry out a survey of any Cat A space and advise you on what additional works are required to bring it to the standard you need.

A Cat B fit out covers all the occupier-specific elements that turn a Cat A space into a fully functional, branded working environment. This includes internal partitioning and layout, meeting rooms, bespoke joinery and reception desks, final floor and wall finishes, decoration, kitchen and welfare areas, furniture and IT infrastructure. Essentially, everything that makes the space reflect your business and enables your team to work in it from day one.

Yes. CUBED can manage Cat A and Cat B fit out as a combined programme, which is often more efficient and cost-effective than using separate contractors for each stage. This is particularly common where a developer is fitting out a space for a pre-agreed occupier, or where a business is taking a shell and core space and requires the full journey from base build to finished workplace. Contact us to discuss your specific requirements.

Timescales depend on the size and complexity of the project. A straightforward Cat B fit out of a small commercial space can be completed in a few weeks. A full Cat B fit out of a large multi-floor office will typically take several months. CUBED will agree a realistic programme with you at the specification stage and manage the delivery against it. We also have experience of delivering Cat B fit outs under tight lease-driven deadlines where a fast turnaround is required.

In many cases, Cat B fit out works do not require a building warrant from your local authority in Scotland. However, structural alterations, significant changes of use, alterations to fire escape routes or certain mechanical and electrical installations may require formal consent. CUBED will advise you on this during the consultation stage. We also offer a dedicated Building Warrant and Listed Building applications service where formal consent is required.
