Cat B Fit Out Delivery for Operational Offices in London
Cat B fit out delivery requires close coordination between design, landlord requirements, and on-site installation. We manage this process carefully, aligning approved layouts with existing building systems, programme constraints, and final finishes to ensure a smooth transition into occupation.
Each project is developed in line with landlord approvals and compliance requirements. This includes working to the landlord’s design pack, managing the Licence to Alter process, and securing sign-off on mechanical and electrical proposals before works begin. Early alignment reduces the risk of delays, redesign, or disruption once the programme is underway.
We coordinate all elements of the fit out, including partitioning, joinery, MEP integration, furniture installation, and finishes. Particular attention is given to how Cat B works connect with base build systems, such as chilled water, ventilation, and life safety infrastructure, where strict building protocols must be followed.
Works only proceed once approvals are in place and sequencing is clearly defined. This keeps the programme controlled and ensures the space is complete, compliant, and ready for immediate use.
What Does a Cat B Fit Out Include?
The scope of a Cat B fit out will vary depending on the building, lease obligations, and how the workspace is intended to function.
Usually Cat B works include:
- Partitioning to form meeting rooms, offices, and breakout areas
- Bespoke joinery, including tea points, storage, and reception areas
- Floor finishes, wall treatments, and ceiling installations
- Mechanical and electrical works, including power distribution and lighting
- Furniture installation and workspace setup
- Branding and signage elements where required
We deliver elements in line with approved layouts, coordinating with any existing building systems. Our contractors take extra care to ensure installations align with landlord requirements, particularly where works connect into central plant, life safety systems, or shared infrastructure.
Early coordination allows the design, approvals, and installation to move forward without conflict, keeping the programme on track as works progress on site.
Managing Programme Risk Across Cat B Fit Outs
Our Cat B fit outs bring together landlord approvals, MEP coordination, procurement, and on-site installation within a single programme. Without careful alignment, these dependencies can affect timelines and introduce disruption during delivery.
We manage programme risk by aligning design, approvals, and construction sequencing from the outset. Key stages such as Licence to Alter approval, design sign-off, and MEP validation are addressed early, reducing the likelihood of late changes once works are underway.
Close coordination is maintained across landlords, consultants, and specialist contractors throughout the project. This allows issues to be identified and resolved early, before they impact progress on site.
By maintaining control over sequencing, access, and integration with base build systems, Cat B fit out delivery remains on programme, with the completed space ready for occupation as planned.

Cat B Office Fit Out FAQs
What is included in a Cat B office fit out?
A Cat B office fit out includes the installation of partitions, meeting rooms, joinery, finishes, and mechanical and electrical services required to create a fully operational workspace. This also involves integrating these elements with existing building systems and ensuring all works align with approved designs and landlord requirements.
Do I need landlord approval for a Cat B fit out?
Yes, landlord approval is typically required before any Cat B fit out works can begin. This is usually formalised through a Licence to Alter (LTA), alongside compliance with the landlord’s fit-out guide and lease conditions. Works cannot proceed until these approvals are fully agreed and documented.
What is a Licence to Alter (LTA)?
A Licence to Alter is a formal agreement between the tenant and landlord that sets out the scope of proposed works and the conditions under which they can be carried out. It forms a critical part of the approval process and must be completed before construction starts.
Can works start before approvals are in place?
No. Cat B fit out works should not begin until all required approvals are secured, including landlord consent and any relevant statutory approvals. Starting early can lead to delays, additional costs, or the need for rework if designs are not fully approved.
What statutory approvals may be required for a Cat B fit out?
Depending on the building, this may include Building Control approval, Planning Permission, or Listed Building Consent. Listed Building Consent can take around 12 weeks to obtain, so these requirements should be identified early and built into the programme.
Why is MEP coordination important in a Cat B fit out?
Mechanical and electrical systems must integrate with the base build infrastructure, including services such as chilled water, ventilation, and fire safety systems. Poor coordination can lead to delays, system conflicts, or compliance issues, particularly in complex commercial buildings.
