Fit-Out Types

CAT A & CAT B Fit-Outs
Explained

Understanding which type of office fit-out you need is the first step. Here's how the two main categories differ — and how we can help with both.

CAT A

Landlord's Base Build

A CAT A fit-out brings a shell-and-core space up to a basic lettable standard. It provides all the fundamental building services without any occupier-specific fit-out. Typically delivered by landlords before a tenant takes occupation.

✓Suspended ceilings and ceiling grid
✓Raised access flooring
✓Basic mechanical and electrical services
✓HVAC distribution
✓Perimeter trunking and power
✓Internal surface finishes (painted walls)

CAT B

Complete Occupier Fit-Out

A CAT B fit-out takes a CAT A space and transforms it into a fully functional, branded office tailored to the occupier's needs. This is the fit-out that takes you from an empty shell to a space you can move straight into.

✓Partition walls, meeting rooms & breakout areas
✓Bespoke joinery and reception features
✓Flooring finishes (carpet, LVT, tiles)
✓Data cabling and AV infrastructure
✓Decoration, branding and graphics
✓Kitchen, welfare and breakout facilities

FAQ

Office Fit-Out
Frequently Asked Questions

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

A CAT A fit-out is the landlord's base build — providing ceilings, lighting, flooring, HVAC and electrics to a blank canvas standard. A CAT B fit-out goes further, adding partitions, joinery, branding and finishes to make the space fully ready for occupation. Most occupiers require a CAT B fit-out to move in.

How much does an office fit-out cost? ▼

Office fit-out costs vary depending on specification and scope. As a guide, basic fit-outs typically range from £40–£55 per sq ft, mid-range from £55–£85 per sq ft, and high-specification fit-outs from £85+ per sq ft. We provide transparent, itemised quotes after a free no-obligation site visit — call us on 020 3393 9600 to get started.

How long does an office fit-out take? ▼

Timelines depend on the size and complexity of the project. A smaller CAT B fit-out can be completed in a matter of weeks, while larger or phased projects may take several months. We provide a detailed programme at the outset so you can plan your move with confidence.

Can you work around our existing office operations? ▼

Yes. We offer phased delivery, out-of-hours and weekend working to keep your business running throughout the fit-out. Our project managers carefully plan work sequences to minimise any disruption to your team and ensure active areas remain safe and accessible at all times.

Which areas do you cover for office fit-out? ▼

Our primary coverage area is London, Kent, Surrey, Essex and the wider South East. We also take on selected projects nationally for established clients. Get in touch to discuss your specific location.
