Will office refurbishment require building control approval?

Building control approval depends on the work, the existing building and how the refurbished space will be used. A straightforward decorative refresh may not need an application, while changes affecting the building’s structure, escape arrangements or services may require formal approval.

Building regulations can apply to more than construction work. They may cover:

• Structural alterations, including changes to load-bearing walls, floors or supporting elements.
• Mezzanine floors, where the structure, loading, stairs, guarding and fire arrangements need consideration.
• Partitioning that changes protected routes, fire compartments, room layouts or escape paths.
• Alterations to fire detection, alarm arrangements, emergency lighting or other life-safety provisions.
• Changes affecting access, ventilation, heating, sanitation, drainage or energy performance.
• Changes in how the premises are occupied, particularly where the new use creates different fire, access or occupancy requirements.

Approval is separate from planning permission. Planning may control the building’s use, external appearance or structural changes, while building control considers whether the work meets applicable building regulations. A project may need one, both or neither. Landlord, freeholder or lease requirements can also apply independently.

Do not assume that removing an internal wall, adding offices or installing partitioning is automatically exempt. The impact on escape routes, fire separation, accessibility and ventilation can determine whether building control input is needed. The same applies to an office fit-out within an existing warehouse or commercial unit.

For a mezzanine floor, building control will generally need clear information about the proposed structure and its use. This can include imposed loads, supporting arrangements, stairs, guarding, fire protection and the relationship with existing services. Storage use may create different requirements from light office accommodation.

Before work starts, establish the project scope and check available information about the premises. Existing drawings, previous approvals, structural details, fire strategies and service layouts can help reveal constraints. A site survey can then compare those records with actual conditions.

We can review the proposed office fit-outs, partitioning, mezzanine floors and related layout changes with you. A no-obligation consultation may include a site meeting and survey, followed by written proposals and working drawings. This process helps identify where building control input may be needed before installation planning advances.

Working drawings should show the intended layout clearly, including partitions, access routes, stairs, doors, storage areas and relevant safety features. Where structural or fire-related information is required, the appropriate competent professional or building control body may need to review it. We do not present a drawing package as approval in itself.

Building control may request further information, inspect work at specific stages or require changes before issuing completion documentation. The exact process depends on the project and the building control route selected. Keep approval records and completion documents with the premises information for future alterations, occupation or sale.

Project management can be included where required, from proposal and tender stages through installation and final commissioning. This can give you one coordinated route for layout decisions, drawings, contractors and site work. It does not remove the need for approvals or decisions that sit with you, the landlord or the relevant authorities.

For a clear view of the likely requirements, provide the existing layout, intended use, proposed changes and any landlord information. We can then assess the scope with you and identify which elements need further building control discussion before work proceeds.
