A Cat A specification would include a floor (where a raised floor is provided), ceiling, lighting, air conditioning (where provided) and items installed such as lifts and WC’s.

Commonly abbreviated to “Cat B” – This is the technical name given to an occupier fit-out/build-out. This would include divisional walls, meeting rooms, reception area, kitchen area and any other modification required as part of the built-out.

At the end of a Lease the Tenant is usually obliged to reinstate the premises into the condition, either as they took it or as described in the Lease. Any building works to achieve this are known as dilapidations.

Also abbreviated to FR&I – This is a typical lease structure for a self-contained building or an “effective Full Repairing Lease” by way of the Service Charge in a multi-occupied building. This means that the Tenant is responsible, either solely or collectively (where multi-tenanted), for the exterior repairs to the building.

It is common for rents to be described as a flat monetary value. Example: £40.00psf. This means the rental is £40.00 per square foot per annum, exclusive of rates and service charge. Despite the introduction of metric sizes, the office leasing market still works on an imperial basis.

This is a document which is used to demonstrate the state of repair at the start of the Lease. It is common for it to be photographically based and is used at the end of the Lease when agreeing dilapidations with the Landlord.

This is the term given to offices which have not received a Category A finish by the Developer. The units typically will have concrete floors, walls and ceiling with no lighting, electricity, air conditioning or services installed.
