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. It essentially creates a clean, blank canvas, ready for a tenant to move in and implement their own bespoke interior design (known as a CAT B fit-out).When our team delivers a CAT A project in the UK, it typically involves:Core Mechanical and Electrical (M&E) Services: Installing main HVAC (heating, ventilation, and air conditioning) systems, primary electrical wiring, and distribution boards.Fire Safety Compliance: Fitting primary fire alarm systems, smoke detectors, and essential sprinkler coverage to meet UK building regulations.Internal Finishes: Installing standard raised flooring, suspended ceilings, and basic lighting grids.Common Areas: Finishing essential structural elements, core plumbing, and basic restroom facilities.For landlords, a high-quality CAT A fit-out by 4construct is vital to maximizing asset value and making the property instantly marketable to prospective commercial tenants. We focus on delivering energy-efficient infrastructure that lowers future operational overheads, ensuring your property is future-proofed against tightening UK efficiency standards. Contact our team to discuss your property's fit-out requirements.

At 4construct, we find that CAT A fit-out costs in the UK typically range from £35 to £80 per square foot (approximately £375 to £850 per square meter). Because commercial properties vary drastically in structural condition and mechanical complexity, the final investment is heavily driven by the building's baseline infrastructure.We generally categorize these project budgets into three main scopes:Standard CAT A (£35 to £55 per sq ft): Best for modern, structurally sound spaces. This covers basic installations of standard raised flooring, suspended ceilings, basic grid LED lighting, and extensions of existing HVAC ducting.Premium or Complex CAT A (£55 to £80 per sq ft): Common for older commercial buildings, heritage sites, or projects requiring an entire overhaul of the primary Mechanical and Electrical (M&E) infrastructure. This includes installing brand-new, energy-efficient central plant systems to comply with current UK efficiency laws.Turnkey / Landlord Plug-and-Play (£80+ per sq ft): An emerging UK trend where landlords request an enhanced CAT A spec that includes basic partitioning and kitchenettes to attract tenants wanting immediate move-in capabilities.Partnering with 4construct ensures an optimized baseline that appeals to incoming tenants while controlling your capital expenditure.

At 4construct, we find that the timeline for a CAT A fit-out in the UK depends heavily on the total floor area and the baseline condition of the building's services. On average, the on-site construction phase ranges anywhere from 4 to 14 weeks.Here is how we typically break down the project duration:Small to Medium Spaces (up to 5,000 sq ft): Typically takes 4 to 8 weeks. This scope usually involves straightforward installations of raised flooring, suspended ceilings, standard LED lighting grids, and extending existing HVAC and fire alarm systems.Larger Commercial Floorplates (5,000 to 20,000 sq ft): Generally requires 8 to 14 weeks. The extended timeline accounts for more extensive distribution of primary M&E services across larger zones, alongside testing and balancing complex ventilation networks.Complex or Multi-Floor Projects (20,000+ sq ft): Can span 4 to 6+ months, particularly if the building requires a complete central plant overhaul or major structural remediation.Remember to factor in an additional 3 to 5 weeks for pre-construction, which covers spatial planning, material procurement, and building control approvals. At 4construct, we prioritize strict programming to ensure your property hits the market on schedule. Contact us to build your precise timeline.
