Fire safety in 2025 is under more scrutiny than ever. With new legislation and increased enforcement, developers, contractors, and clients must take greater responsibility for ensuring their buildings are safe. Whether it’s a multi-storey block in London or a small commercial unit in Sussex, every build must be compliant, and fire safety is a major part of that.
 
This is where building control plays a vital role. At every stage of a project, from the drawing board to final inspection, a Registered Building Control Approver (RBCA) like All Building Control ensures your fire safety measures aren’t just in place—but properly designed, installed, and maintained. So, what exactly are your responsibilities, and how can you ensure you meet them?

Why Fire Safety Can’t Be an Afterthought

Since the introduction of the Building Safety Act, fire safety is no longer considered a final checklist item. It must be embedded into the design and construction process from the start. There is now a clear, legal expectation that everyone involved in a build—clients, contractors, designers—has a defined role in ensuring fire safety standards are met.
 
Failing to meet those duties doesn’t just slow down a project; it also undermines its effectiveness. It can lead to stop notices, failed inspections, removal of unsafe work, or even prosecution. In a regulatory environment that continues to tighten, early-stage fire risk planning is no longer optional—it’s essential.

What Fire Safety Elements Are Assessed?

Fire safety isn’t limited to sprinklers or alarms. It influences everything from a building’s layout to its materials. As part of building control, fire provisions are assessed through plan reviews and on-site inspections.
 
Two key areas where fire safety is scrutinised include:

Compartmentation: Internal walls, floors, and ceilings must be constructed to delay the spread of fire and smoke between rooms and levels. This is especially critical in blocks of flats, commercial buildings, or multi-use spaces.

Means of escape: Buildings must provide safe, protected routes out of the premises for all occupants. This includes clear signage, proper door configurations, and emergency lighting where needed.

Inspectors also assess elements such as fire door installation, cladding safety, alarm systems, and evacuation strategies, depending on the building’s complexity and use.

Understanding the Legal Roles: Who Is Responsible?

A major change in how fire safety is handled is the introduction of clearly defined roles for duty holders. This structure clarifies legal responsibility across the project lifecycle, ensuring that no one can shift blame or ignore their obligations.
Those roles include:
 
  • The client is responsible for ensuring that competent professionals are appointed and safety is considered from the outset.
  • Principal designer – accountable for fire safety during the design phase, including layout and material choices.
  • Principal contractor – ensures fire precautions are implemented on-site and that workers follow approved plans.
  • Designers and contractors are responsible for ensuring that their individual contributions comply with regulations.
  • Building Control Approvers – verify that everything meets the standards outlined in the building regulations, including fire protection.
When these roles work together, risk is reduced, and sign-off is smoother. When they don’t, projects stall, and serious fire hazards can go unnoticed until it’s too late.
Early Engagement Prevents Fire Safety Failures
One of the most common causes of non-compliance is engaging building control too late in the process. When fire strategy isn’t discussed until construction is well underway, retrofitting solutions become expensive, time-consuming, and sometimes impossible without structural changes.
 
Working with a Registered Building Control Approver at the design stage allows problems to be identified early, before they affect the build. You’ll also receive support in selecting compliant materials, planning safe evacuation routes, and avoiding common pitfalls that lead to failed inspections. It’s an approach that saves time, avoids rework, and, most importantly, ensures a safer outcome for end users.
How All Building Control Supports Fire Safety Compliance

  • Inspections timed with critical fire safety elements (e.g., compartmentation or fire stopping)
  • Collaboration with design and contractor teams to close any compliance gaps
  • Verification of key fire safety products and systems
  • Support for high-risk building types under the Building Safety Act
Whether you’re a developer, architect, or contractor, we ensure that every decision you make around fire safety is backed by expert oversight and clear guidance.
