Frequently asked questions
The following questions reflect those most commonly raised by clients and design teams when appointing a Principal Designer.
When is a Principal Designer required?
A Principal Designer is required on projects that fall within the scope of the Building Regulations where more than one designer
is involved, or is reasonably foreseeable.
The role exists to plan, manage, and coordinate design work in relation to building safety and regulatory compliance.
Does every project need a Principal Designer?
No. The requirement depends on the nature, scale, and regulatory scope of the project.
Early discussion is often helpful to confirm whether the role applies and, if so, what level of involvement is proportionate.
Can the architect act as Principal Designer?
In some cases, yes. However, the Principal Designer role brings specific statutory duties and accountability.
Where the architect is already carrying significant design responsibility, appointing an independent Principal Designer can provide
clarity, support compliance, and avoid conflicts of role.
Do you take over design responsibilities?
No. Designers retain responsibility for their own design work.
Our role is to coordinate, oversee, and support the management of design risk and compliance, not to replace or duplicate the work
of architects, engineers, or specialist designers.
How do you work with existing design teams?
We work alongside established design teams, embedding the Principal Designer role within the design process.
This allows other professionals to continue working within their traditional roles, while ensuring that coordination, information flow,
and regulatory oversight are maintained.
What if we are close to starting work on site but still need to appoint a Principal Designer?
Yes, we can help.
Where a Principal Designer is appointed late in the process, we will need to review the relevant design information and documentation
to understand how design risk and regulatory requirements have been addressed to date, and to identify any gaps that may need to be resolved.
This review is necessary to allow the Principal Designer role to be discharged properly and will be approached in the same structured way
as if we had been instructed earlier in the project.
The scope and programme of this work will be agreed proportionately, taking into account the stage the project has reached and the information available.
When should a Principal Designer be appointed?
Appointment should be made as early as possible in the design process.
Early involvement supports proportionate planning, avoids late-stage compliance issues, and provides continuity as the design develops.
Do you work on small projects?
Yes. The Principal Designer role is scalable and should always be proportionate to the size and complexity of the project.
Our involvement is tailored accordingly, ensuring appropriate oversight without unnecessary burden.
Is the Building Regulations Principal Designer the same as the CDM Principal Designer?
No. Although the role titles are similar, they arise from different legislation and have different focuses.
The CDM Principal Designer role is concerned with health and safety during construction, while the Building Regulations Principal Designer role
focuses on planning, managing, and coordinating design work in relation to building safety and regulatory compliance.
In some cases, the same organisation may undertake both roles, but each role must be considered and appointed separately.
What does “competence” mean for a Principal Designer?
Competence relates to having the appropriate skills, knowledge, experience and behaviours to carry out the role, as well as sufficient
organisational capability and capacity.
Where the Principal Designer is an organisation, a suitably competent individual must be designated to manage and discharge the function.
What happens if a Principal Designer ceases to be competent or leaves the project?
If a Principal Designer ceases to satisfy the competence requirements during a project, or is replaced, they must inform the client.
The client and any newly appointed Principal Designer would then review the existing arrangements and agree the appropriate steps to ensure
the role continues to be discharged in accordance with regulatory requirements.
What documentation does a Principal Designer provide?
A Principal Designer keeps records of how they plan, manage, and coordinate design work, and how reasonable steps have been taken to support
compliance with the Building Regulations.
There is no single prescribed format for this documentation, but it supports transparency and assists clients, design teams, and regulators
in understanding how the Principal Designer duties have been discharged.
What if there is only one designer or one contractor on a project?
Where there is only one designer involved in a project, that designer is treated as fulfilling the Principal Designer duties unless a separate
written appointment is made.
Similarly, where there is only one contractor, that contractor is treated as fulfilling the Principal Contractor duties. These provisions help
ensure that responsibilities remain clear even on small or simple projects.
Do you use artificial intelligence (AI)?
Yes. We use AI as a support tool for activities such as research, drafting, administration, and general communications.
AI does not make decisions affecting Building Regulations compliance or replace professional judgment. Where AI language models are used, this is
done in private or controlled modes and in accordance with UK GDPR and data protection obligations, with appropriate safeguards in place to protect
confidentiality and data security.
Further details are set out in our AI Use Policy.
