Category A fit-out

There is no standard definition for a category A fit out and it can vary from developer to developer. Most often, it describes the level of fit out provided by the developer to the landlord.

Typically, a Cat A fit out includes:

  • Raised floors and suspended ceilings.
  • Basic mechanical and electrical services.
  • Fire detection and protection services.
  • Internal surface finishes.
  • Blinds.

You quite often find that the developer will make a contribution to the tenant for the carpets, floor boxes and grommets, which are then installed as part of the tenants category B fit-out, rather than installing them during the category A works, as they are subject to damage and may not complement the tenants colour scheme.

Category B fit-out

This is the type of fit out that most people are more familiar with. A Category B fit out is conducted on a space where the external walls and basic flooring, ceilings, M&E services and shared toilets and lifts have been installed. It's like moving into a house and then installing your choice of flooring, lighting and decoration to make it your own personal space.

Typically, a Cat B fit out includes:

  • Partitioning.
  • Finishes and branding.
  • Carpeting.
  • Meeting rooms, conference rooms and break-out rooms.
  • Reception area.
  • Lighting.
  • Kitchen facilities.
  • IT and audio visual equipment.
  • Office furniture.

At Trevor Blake we carry out both Cat A fit-outs and Cat B fit-outs. Where a company is required to bring an office back to its Cat A condition for hand over to the landlord, we provide a dilapidations service which typically involves the stripping out of partitioning, flooring, decorating and furniture.
