Offices – definitions of Cat A & Cat B fit outs
There is no universal or absolute definition of ‘Shell and Core’, ‘Category A’ or ‘Category B’ fit outs. However the following definitions describe what can be assumed to be included:
Shell and Core
The building is completed to the following specification: Complete fit out of reception / entrance halls, staircases, communal areas, toilets, lifts and core. To include Base Services’ plant and equipment terminated at breakout points to floors. Basic safety infrastructure – sprinkler systems, tanks and risers, fire alarm panel and emergency standby generator.
The above Shell & Core works are usually completed before Select Interiors are employed.
Reception – PZ Cousins Manchester reception & core fit out. Select Interiors carried out high specification joinery, finishing and management works on this project for Main Contractor Preferred Office Environments. Managing Director Carl was tasked with liaising directly with Chief Architect and designer of the £2 million scheme to final completion of finishes.
PZ Cousins – Manchester Airport Site
Category ‘A’
These works include the completion of the base building works to the shell and core. Works also usually include a level of fitting out between the shell and core to the point at which internal components must be designed to a specification for the end user, (known as Category ‘B’).
Category A Fitting out elements will usually include: Suspended ceilings, raised floors, basic mechanical and electrical services – lighting, heating, ventilation, cooling and associated control systems. All wall and floor finishes to cores, fully fitted out WCs; sprinklers, fire alarms, safety signage and distributed power small power to each floor

Category B Fitting out elements will usually include: suspended ceiling upgrades and modifications, internal partitioning, floor finishes (other than office carpet). Completion of mechanical and electrical services to tenant’s specification. Specific items of systems plant and equipment – ventilation and lighting to suit tenant’s requirements. Alterations to raised access floors, installation of containment, small power and data cabling.

I hope the explanation above will help you the reader a better understanding of Landlord terms. It can be confusing looking at lease arrangements and the associated paperwork, what will and what won’t be included in Cat A. The pie chart and images are a snap shot of how costs were apportioned on a recently completed project. All contracts differ, I hope this barometer of costs and the accompanying images will help demystify the fit out process and where the money is spent
