Why Fire Dampers Will Matter More Than Ever in 2026

The Building Safety Act is reshaping expectations across design, construction and building management — and one component that is receiving unprecedented scrutiny: fire and smoke control dampers.

Once considered a routine part of HVAC design, dampers are now recognised as critical life-safety devices essential to compartmentation, smoke control and a building’s overall fire strategy. As competency requirements increase and accountability becomes more transparent, correct specification, installation and maintenance have never been more important.

Causes of Damper Failure in Fire Safety

Raising the Bar on Competency & Compliance

Under the Act, duty holders, designers and contractors must now demonstrate competence when selecting and integrating life-safety products. Fire and smoke control dampers fall firmly into this category, because a non-compliant or poorly installed damper can:

  • Compromise compartmentation
  • Allow smoke to spread
  • Undermine the fire strategy
  • Jeopardise the building’s safety case
  • Lead to costly remediation

This places new pressure on project teams to ensure damper decisions are informed, appropriate and traceable.

The Golden Thread: Traceability and Verification

The Golden Thread requires clear, accurate and accessible information through a building’s lifecycle. For dampers, this includes:

  • 3rd party Verified certification and BS EN classification
  • Test evidence
  • Installation and as-tested details
  • Access provision for maintenance
  • Control strategy and actuator configuration aligned with Fire strategy cause & effect

Poor or incomplete documentation or incorrect installation is no longer a minor oversight — it is a compliance failure.

Why Dampers Are Under Greater Scrutiny

  1. Performance Matters to Life Safety

Dampers directly influence fire containment, smoke movement and escape route protection.

  1. “Compliant” Products Can Still Fail

Incorrect installation — such as formation of the aperture, incorrect fixing, unsuitable fire-stopping, or missing access — prevents a certified damper from performing as tested and prevents the required maintenance during the life-time of the building, often resulting in additional remedial cost for the building owner/occupier.

  1. Wrong Damper Type = Wrong Outcome

Mis-specifying a fire damper, motorised or mechanical or where a smoke control damper is required (or vice versa) remains a common and high-risk error.

Accountability for Contractors & Consultants

Project teams must now evidence:

  • Competent specification
  • Correct product selection
  • Installation in line with test evidence
  • Adequate access for inspection
  • Complete Golden Thread documentation

When competency or documentation is lacking, responsibility sits firmly with the project team.
