Question 1

In the UK, what is involved in a CAT A Fit-Out?

Accepted Answer

At 4construct, we define a CAT A fit-out as the process of bringing a commercial or industrial space up to a basic, functional landlord standard, creating a clean, blank canvas for incoming tenants. It typically involves installing core Mechanical and Electrical (M&E) services like primary HVAC systems and electrical wiring; implementing fire safety compliance including fire alarms, smoke detectors, and sprinkler coverage; completing internal finishes such as raised flooring, suspended ceilings, and basic lighting grids; and finishing common structural areas like core plumbing and restroom facilities.

Question 2

In the UK, how much do CAT A Fit-Outs cost?

Accepted Answer

At 4construct, we find that CAT A fit-out costs in the UK typically range from £35 to £80 per square foot (£375 to £850 per square meter). Budgets generally fall into three tiers: Standard CAT A (£35 to £55 per sq ft) for modern spaces requiring standard floors, ceilings, and lighting extensions; Premium or Complex CAT A (£55 to £80 per sq ft) for older buildings requiring a complete overhaul of central mechanical and electrical infrastructure; and Turnkey / Landlord Plug-and-Play (£80+ per sq ft) which introduces enhanced specifications like basic partitioning and kitchenettes.

Question 3

How long can a CAT A Fit-Out take in the UK?

Accepted Answer

The on-site construction phase for a UK CAT A fit-out typically ranges from 4 to 14 weeks on average. Small to medium spaces up to 5,000 sq ft take roughly 4 to 8 weeks. Larger commercial floorplates between 5,000 and 20,000 sq ft generally require 8 to 14 weeks to manage extensive M&E zoning. Complex or multi-floor projects over 20,000 sq ft can span 4 to 6+ months, especially if a complete central plant overhaul is required. We also advise factoring in 3 to 5 weeks for pre-construction planning and building control approvals.
