Avoiding the “Late Appointment Trap” – Why Early Principal Designer Appointment Matters Under the Building Safety Act

Delaying the appointment of a Principal Designer to save on initial costs can often lead to what we call the “Late Appointment Trap” — a situation that ends up costing developers significantly more time and money.

Under the Building Safety Act, the Principal Designer plays a critical role that must begin early in the design process. Appointing too late — such as just before construction starts or during the building control submission stage — can create serious challenges for your project.

The Risks of Late Principal Designer Appointment

Waiting too long before appointing a qualified Principal Designer often results in:

  • Abortive Work & Redesign Costs — Fundamental design decisions made without Building Safety Act compliance input may need to be reworked.

  • Significant Programme Delays — Late changes can push back construction timelines and affect overall project delivery.

  • Unexpected Additional Fees — Rushed compliance work and variations often increase professional fees.

  • Increased Risk — Potential gaps in duty holder responsibilities and safety oversight.

Why Early Involvement is Essential

Appointing a Principal Designer at the earliest feasible stage (ideally during concept or feasibility) brings major advantages:

  • Early identification of compliance issues

  • Integration of Building Safety Act requirements into the core design

  • Smoother planning and building control processes

  • Better risk management and cost control

  • A more coordinated project team from the outset
