Specialist Cat A Fit-Out Contractors in London
Our Cat A fit out services in London prepare commercial spaces for occupation, combining essential infrastructure, integrated building systems and high-quality finishes aligned with landlord standards.
Cat A Fit Out Delivery for London Workspaces
A Cat A fit out sets the foundation for occupation, putting in place the core systems and finishes required before a space is handed over. We manage this stage of works across London buildings, aligning delivery with landlord standards and the practical realities of each site.
Lighting, ceilings, raised floors, HVAC and power distribution are installed and coordinated as part of a fully integrated package. Where existing mechanical and electrical infrastructure is in place, we assess and adapt it to ensure everything is compliant, tested and ready for use.
Programme planning is shaped by landlord requirements, statutory approvals and building-specific constraints. Fit-out guides, lease obligations and approval processes are built into the delivery strategy from the outset to avoid delays and rework.
On completion, the space is fully prepared for tenant fit out or occupation, with systems commissioned, certified and aligned with building and regulatory requirements.

- Suspended ceilings with integrated lighting

Delivering Cat A Fit Outs in London Commercial Offices
We understand that commercial buildings across London come with their own constraints, requirements and approval processes. Landlord fit-out guides, lease obligations and building regulations all influence how projects are planned and carried out.
Our team plans each programme to reflect these factors. Statutory approvals, including planning and listed building consent where required, must be secured before works can begin. In parallel, landlord approval processes and technical submissions are coordinated to ensure designs align with building standards.
Many projects also involve working within existing mechanical and electrical infrastructure. Systems such as HVAC, sprinklers and power distribution require careful integration, particularly in occupied or operational buildings where access and sequencing must be managed closely.
By aligning delivery with these conditions early, we ensure works can progress in a controlled and coordinated way, reducing the risk of delays, redesigns or compliance issues during construction.

Cat A Office Fit Out FAQs
What is a Cat A fit out?
A Cat A fit out prepares a commercial space for occupation by installing the core building systems and finishes. This typically includes ceilings, lighting, HVAC, raised floors, power distribution and fire safety systems, delivered in line with landlord and building requirements.
How long does a Cat A fit out take in London?
Timescales depend on the size of the space, building constraints and approval processes. In London, programmes are often influenced by landlord approvals and statutory requirements, which can extend timelines if not factored in early.
Do I need landlord approval for a Cat A fit out?
Yes, most Cat A fit outs require landlord approval. This may involve a Licence to Alter, technical submissions and compliance with fit-out guides. Works cannot begin until approvals are fully in place.
What is the difference between Cat A and Cat B fit outs?
A Cat A fit out delivers the base building infrastructure, making the space ready for occupation. Cat B fit outs take this further by adding layouts, finishes and features tailored to the occupier’s specific requirements.
Can works start before approvals are in place?
No. Works shouldn’t begin until all statutory and landlord approvals are secured.
Starting early can lead to delays, compliance issues, and costly rework. In some cases, the risks are more serious. Carrying out work on a listed building without consent is a criminal offence, and proceeding without landlord approval can put you in breach of your lease.
Fit-out projects involve strict legislation, including the Building Safety Act and CDM regulations. Getting approvals right from the outset helps avoid issues and keeps the project moving.
What approvals are required for a Cat A fit out in London?
Approvals may include landlord consent, planning permission, building control approval and, in some cases, listed building consent. Requirements vary depending on the building and its location.
