Commercial Client FAQs

Common questions

What is the difference between a Cat A and Cat B office fit-out?

A Cat A fit-out delivers a functional, open-plan commercial shell — including raised flooring, ceilings, basic lighting and HVAC — ready for a tenant to rent. A Cat B fit-out customises that interior for the occupant: adding private offices, meeting rooms, IT cabling, kitchen breakout areas, branding and furniture.

Can work take place outside normal office hours?

Yes. In occupied multi-tenant office buildings, we regularly schedule heavy drilling, structural modifications and deliveries during evenings and weekends to comply with building management noise restrictions.

Do you supply building regulation and fire safety sign-off?

Yes. We coordinate directly with Building Control to ensure all partitions, emergency routes, disabled accessibility (Doc M) and electrical/HVAC installations meet statutory commercial standards.
