The enactment of the Building Safety Act 2022 represents a pivotal transformation within the UK’s construction landscape, fundamentally redefining the responsibilities of the Principal Designer. With the Building etc (Amendment) (England) Regulations 2023 having taken effect on 1 October, a new regulatory framework mandates the appointment of both a Principal Designer and a Principal Contractor for any project necessitating a Building Regulations application. This comprehensive requirement applies across the board, from modest domestic house extensions to the more complex and demanding higher-risk buildings (HRBs). The implications of these changes are substantial, prompting a reassessment of roles and the industry’s readiness to adapt.

The Principal Designer role, while not entirely novel, has evolved significantly from its original conception under the Construction (Design and Management) Regulations 2015 (CDM 2015). Initially, the focus for Principal Designers was on managing health and safety risks during the pre-construction phase. However, the Building Safety Act shifts this emphasis towards ensuring compliance with building regulations. This transition underscores a broader strategic intent to guarantee that buildings are not only constructed safely but are also compliant right from the planning stages. In this new paradigm, Principal Designers must now oversee the design process to ensure adherence to the Building Regulations 2010, which encompass a wide range of considerations, from structural safety to environmental sustainability features like electric vehicle charging infrastructure.
One of the most significant divergences between the CDM 2015 framework and the Building Safety Act is the shift in primary objectives. Under CDM 2015, health and safety was paramount, while the Building Safety Act prioritises regulatory compliance. This evolution reflects a growing recognition of the importance of initial design integrity in the lifecycle of a building’s safety and functionality. Principal Designers are now tasked with planning, managing, and monitoring the design work to ensure it meets regulatory criteria. They must coordinate every aspect of design to confirm that the completed construction aligns with statutory standards. This expanded role demands a deep and nuanced understanding of the Building Regulations 2010, as well as the capacity to integrate compliance into the design seamlessly.
However, this regulatory evolution presents several challenges. A critical concern is whether architects and designers are prepared to embrace these expanded responsibilities. Traditionally, architects have been seen as natural candidates for the Principal Designer role due to their central involvement in the design process. Yet, many in the profession have been hesitant to take on the role, often perceiving health and safety as predominantly within the contractor’s domain. A Health and Safety Executive (HSE) research report from June 2023 indicated that health and safety consultants, client advisors, and project managers frequently assumed the Principal Designer responsibilities under the CDM framework, with only 18% of survey respondents being members of the Royal Institute of British Architects (RIBA). This statistic points to a reluctance among architects to fully engage with the Principal Designer role, which could stem from the increased liabilities now associated with it.
The implications for the construction industry are profound. The introduction of the Principal Designer role under the Building Safety Act is one of the most significant regulatory shifts since the 1980s, entailing stricter liabilities and potentially severe sanctions for non-compliance. Nonetheless, it also offers a substantial opportunity for architects and designers to reclaim and expand their influence over the design phase. To effectively discharge the duties of a Principal Designer, professionals must exhibit a robust set of skills, comprehensive knowledge, and relevant experience, combined with the right behaviours to navigate this complex landscape. An intricate understanding of building regulations is essential, as is the ability to manage and coordinate the design process effectively.
As the construction industry acclimatises to these regulatory changes, the role of the Principal Designer stands as a testament to the sector’s commitment to fostering a culture of accountability and regulatory adherence. The challenges are undeniable, yet they also present a unique opportunity for industry professionals to redefine their roles and contribute meaningfully to the creation of safer, more compliant buildings. For architects and designers willing to rise to the occasion, this is a chance to enhance their professional scope and impact. Embracing the responsibilities bestowed by the Principal Designer role will be crucial for those aiming to thrive in this new regulatory environment, ultimately leading to a more resilient and compliant construction industry.
