FAQs

What is the difference between CAT A, CAT A plus and CAT B?

CAT A is the landlord's base-build finish: raised floors, suspended ceilings, perimeter heating/cooling and emergency lighting. CAT A plus adds meeting rooms, kitchen, and sometimes furniture to let to occupiers immediately. CAT B is the tenant's full occupational fit-out: partitioning, branding, joinery, AV and finishes.

How quickly can you mobilise a fit-out?

For a standard CAT B of 5,000–15,000 sqft we can mobilise within 3–4 weeks of instruction, subject to licence-to-alter. A full CAT B programme typically runs 10–16 weeks.

Do you self-deliver M&E or subcontract it?

We self-deliver electrical and small-works mechanical through our in-house team, with specialist subcontractors on chillers, VRF and BMS. All works are covered by the main contract.

Can you handle BREEAM or WELL certification input?

Yes — we work with the project assessor, supply tracked submittals for materials, air-quality data for paints and adhesives, and commissioning reports for M&E.

Will you manage the licence-to-alter with our landlord?

Yes. We prepare the drawings, M&E schedules, method statements and condition schedule required by the landlord's surveyor, and manage the approval process to completion.

How do you price — per sqft or open-book?

Fixed lump-sum against an agreed specification. Variations are priced per item before issue. No percentage preliminaries markups.
