Our CDM and Building Regulations Principal Designer services ensure your project complies with the Building Regulations and Gateways applications for High Risk Buildings (HRBs).
Our experienced team of qualified professionals help you mitigate risk and ensure regulatory compliance.
The Construction Design and Management (CDM) Regulations provide construction legislation around health and safety, from the initial stages of a project through to completion. The Building Safety Act (BSA) introduced a gateway regime for higher risk buildings in 2022 to raise safety standards of all buildings.
The Building Regulations Principal Designer (BRPD) is a statutory appointment, mandatory when there is more than one contractor. The BRPD ensures that the building is designed and constructed in accordance with the current legislation to ensure the safety of future occupants. LRA Retinue has a dedicated and experienced CDM team to fulfil the CDMPD and BRPD roles, and drive your project’s success in health and safety and building regulations compliance.

What is a Building Regulations Principal Designer?
In an era of heightened regulation and safety requirements, understanding your legal duties under the Building Safety Act 2022 is no longer optional, it’s essential. One of the most significant changes is the introduction of the Building Regulations Principal Designer (BRPD) role.
At LRA Retinue, we help clients navigate these regulatory shifts with confidence. This article explains what a BRPD is, what they do, and why your project (no matter the size or complexity)can benefit from our expert BRPD services.
A Building Regulations Principal Designer is a statutory dutyholder under the Building Regulations 2010 (as amended by the Building Safety Act). Their core responsibility? Ensuring compliance with building regulations throughout the design phase, particularly for Higher-Risk Buildings (HRBs) such as high-rise residential developments, hospitals, and care homes.
Unlike the CDM Principal Designer (who focuses on health and safety), the BRPD ensures that the design aligns with fire safety, structural integrity, and other technical regulations—right from the drawing board.
Why does your project need a BRPD
If you’re working on an HRB project in England, appointing a BRPD is now a legal requirement. But even on projects that fall outside the HRB definition, early BRPD involvement offers major advantages:
- Early Compliance Assurance - Avoid costly redesigns and planning delays
- Golden Thread Accountability - Ensure robust, transparent information flow from concept to occupation
- Design Coordination - Seamless alignment of architects, engineers and specialists under one compliance umbrella
Core Duties of a BRPD
At LRA Retinue, our BRPD consultants lead from the front—combining deep technical knowledge with practical site experience. We speak the language of design, regulation, and risk. Appointing LRA Retinue as your BRPD means you’ll benefit from:
