Description
Harmony is on a mission to be the best life safety partner to work with and for. Rated an ‘Outstanding Employer’ by Best Companies in 2025, we are only getting bigger and stronger — and we’re looking for A-players to help us get there.
We are passionate about making a difference and obsessed with quality. Our goal is to build a world where every resident can sleep safely at night, knowing their home is 100% safe.
The Building Safety Act 2022 has fundamentally changed the obligations placed on designers and principal designers across the construction industry. Gateway 2 applications, higher-risk building compliance, and the duties placed on design teams demand a level of regulatory oversight that is now a legal requirement — not an optional extra. Harmony Fire’s Consultancy team is a dedicated construction safety, CDM, and Building Safety Act practice with a strong reputation across the residential and NHS estate sectors, and we are looking for a Building Regulations Principal Designer (BRPD) to fulfil this mission-critical function.
Reporting to the Principal Fire Engineer and working closely with our internal pre-construction teams, facade engineers, and fire and structural engineering colleagues, you will provide the technical and regulatory oversight that ensures our clients and their design teams meet their obligations as designers and principal designers under the revised Building Regulations. This is a hands-on, client-facing role at the heart of some of the most significant building safety programmes in the UK.
Key Responsibilities
- Provide guidance and support to internal pre-construction teams, facade engineers, and fire and structural engineering colleagues in fulfilling their designer and principal designer responsibilities under the Building Regulations for both HRB (Higher-Risk Building) and non-HRB projects.
- Lead and manage Gateway 2 applications for higher-risk buildings, ensuring all required documentation, design compliance evidence, and regulatory submissions are accurate, complete, and delivered on time.
- Develop, implement, and manage processes, strategies, and documentation to demonstrate compliance with Building Regulations as amended by the Building Safety Act 2022.
- Address Building Regulations design queries from internal teams and clients, actively contributing to collaborative, solution-focused outcomes where compliance and buildability are both maintained.
- Review design information and technical documentation to identify and flag Building Regulations compliance risks at the earliest possible stage.
- Support pre-construction teams in structuring their design management approach to meet BRPD obligations, providing practical guidance on documentation requirements and compliance evidence.
- Liaise with Building Control Bodies (BCBs), Registered Building Inspectors, and the Building Safety Regulator as required on behalf of clients and internal teams.
- Maintain up-to-date knowledge of Building Regulations, the Building Safety Act 2022, associated secondary legislation, and guidance, ensuring Harmony’s approach remains current and compliant.
- Contribute to the development of Harmony’s BRPD methodology, templates, and standard documentation, supporting the growth of this function across the consultancy.
- Represent Harmony in client-facing meetings, design team reviews, and regulatory discussions, presenting compliance positions clearly and credibly.
