Introduction: Understanding the Assigned Certifier Role
In the world of construction, extension, and development in Ireland, compliance with Building Regulations is not just a legal requirement — it’s crucial for safety, quality, and protecting long-term investments.
One of the central figures ensuring this compliance is the Assigned Certifier.
At Beacon Building Consulting, we provide professional Assigned Certifier services to guide projects from design through to completion certification. In this comprehensive blog, we explain what an Assigned Certifier is, their role, legal obligations, and how choosing the right professional can make or break your project.
What Is an Assigned Certifier?
An Assigned Certifier is a qualified professional who takes legal responsibility for inspecting and certifying that building works comply with the Building Control (Amendment) Regulations 2014 (BCAR).
The Assigned Certifier is appointed by the building owner and is responsible for:
- Coordinating the inspection plan
- Overseeing inspections during construction
- Collating certificates from designers and builders
- Certifying the building’s compliance upon completion
Typical Assigned Certifiers:
- Chartered Engineers (CEng MIEI)
- Registered Architects (RIAI)
- Chartered Building Surveyors (SCSI)
At Beacon Building Consulting, our Chartered Engineers act as Assigned Certifiers for a wide range of projects across Ireland.
The Legal Basis: Building Control (Amendment) Regulations 2014 (BCAR)
Following high-profile building failures, Ireland introduced BCAR to strengthen compliance and accountability.
Under BCAR, the following must be submitted for certain projects:
- Commencement Notice with additional documentation
- Assigned Certifier appointment
- Design Certificate
- Inspection Plan
- Completion Certificate
Without fulfilling these obligations, works are illegal and can result in refusal of mortgages, insurance, or occupation certificates.
BCAR applies to:
- New dwellings
- Extensions >40 square metres
- Apartments and commercial buildings
BCAR does not apply to:
- Small extensions (<40 sqm)
- Minor alterations and repairs (e.g., window replacements)
Nonetheless, even exempt works must comply with Building Regulations.
The Assigned Certifier’s Main Responsibilities
1. Preparing and Lodging Commencement Notice Documents
- Design Certificates from designers
- Assigned Certifier appointment form
- Inspection Plan for construction stage
2. Coordinating the Inspection Process
- Carrying out site inspections at key stages
- Ensuring inspections by specialist certifiers where necessary (e.g., fire safety, M&E)
- Recording inspections and findings
3. Managing Certificates from Designers and Contractors
- Collecting Ancillary Certificates from:
- Structural engineers
- M&E engineers
- Fire safety consultants
- Contractors and subcontractors
4. Certifying Completion
- Confirming that the building complies with Building Regulations
- Submitting the Certificate of Compliance on Completion to the Building Control Authority
The Assigned Certifier’s name and details are entered on the public Building Control Management System (BCMS).
The Difference Between Assigned Certifier and Design Certifier
It’s common to confuse these roles — but they are distinct:
|
Role |
Responsibilities |
|
Design Certifier |
Certifies that the design complies with Building Regulations |
|
Assigned Certifier |
Certifies that the building was built in accordance with the certified design and Building Regulations |
Often, structural engineers (like Beacon Building Consulting) can act as both Design Certifiers and Assigned Certifiers on appropriate projects.
Projects That Require an Assigned Certifier
|
Project Type |
Assigned Certifier Required? |
|
New single dwelling |
Yes |
|
Extension >40 sqm |
Yes |
|
Apartment development |
Yes |
|
Commercial units |
Yes |
|
Shop fit-out (minor) |
No (if no material alterations) |
|
Minor domestic alterations |
No (but compliance still required) |
Failure to appoint an Assigned Certifier where required is a breach of the Building Control Acts.
Why Appoint an Assigned Certifier Early?
Appointing an Assigned Certifier at the early design stage ensures:
- Proper BCAR documentation is prepared in advance
- Inspection planning is aligned with construction programme
- Coordination with all designers and contractors is seamless
- Avoidance of costly delays at Commencement Notice stage
Beacon Building Consulting works proactively with clients, architects, and contractors from day one.
Typical Inspection Stages
Assigned Certifiers inspect at critical milestones, such as:
- Foundation excavation and formation
- Installation of radon barriers
- Drainage installations
- Superstructure completion (walls, roofs)
- Fire safety measures (compartmentation, detection systems)
- Final completion snagging
The Inspection Plan is tailored to each project’s nature, complexity, and risk profile.
Typical Project Scenarios: When an Assigned Certifier Is Essential
Sample Scenario 1: New Family Home Construction
A family building a new 4-bed home needs an Assigned Certifier to manage compliance documentation, conduct inspections, and certify the home’s completion to secure a mortgage drawdown.
Sample Scenario 2: Large Commercial Extension
An office building adding a 60 sqm rear extension appoints an Assigned Certifier to satisfy BCAR obligations and ensure final insurance coverage.
Sample Scenario 3: Multi-Unit Apartment Development
A developer constructing 12 apartments must submit an Inspection Plan and Completion Certificate via BCMS, coordinated and certified by an Assigned Certifier.
FAQs: Assigned Certifiers in Ireland
Q: Can my architect be my Assigned Certifier?
Yes, if they are registered with the RIAI. Alternatively, a Chartered Engineer or Chartered Building Surveyor can fulfil the role.
Q: Can the builder be the Assigned Certifier?
No. The Assigned Certifier must be a qualified design professional, independent of the contractor.
Q: How much does it cost to appoint an Assigned Certifier?
Fees vary depending on project size, complexity, and inspection scope. Beacon provides clear, tailored quotations.
Q: What happens if I don’t appoint an Assigned Certifier when required?
Your project will be non-compliant with BCAR, risking:
- Planning enforcement action
- Difficulty selling or insuring the building
- Refusal of mortgages
Q: Does the Assigned Certifier design the building?
Not necessarily. They coordinate compliance. Structural, fire, and M&E designs are typically done by specialist consultants.
