Building Regulations Principal Designer
Compliance made clear, co-ordinated and confident.
The Building Regulations Principal Designer (BRPD) role was introduced under the Building Safety Act to strengthen accountability and ensure that every building project is safe and compliant by design. OSG has embraced this responsibility from the start. Based in Kent and working across London and the South East, we provide BRPD services that give clients, contractors and design teams complete confidence that compliance is being managed by experienced professionals.
Whether appointed as lead designer or as a stand-alone BRPD, our role is to plan, manage and monitor design work so that the finished building meets every requirement of the Building Regulations, efficiently, transparently and without delay.
What our BRPD service offers
Our BRPD team combines technical expertise with practical understanding. We work as part of your project team, helping to maintain compliance, reduce risk and keep programmes on track.
■ Full compliance with the latest Building Regulations.
■ Independent BRPD appointments where the lead designer is unavailable or unwilling.
■ Rapid mobilisation for fast-start or complex projects.
■ Co-ordination with contractors, QSs and project managers to de-risk approvals.
■ Proven capability on high-risk buildings, refurbishments and mixed-use developments.
How clients benefit
Appointing OSG as your BRPD gives you a partner who brings structure and assurance to the design process.
■ Reduced risk – proactive management avoids compliance issues before they arise.
■ Time and cost efficiency – early involvement keeps projects moving smoothly through approval.
■ Flexible integration – we work seamlessly alongside existing design teams.
■ Confidence in delivery – every decision and document is backed by technical expertise and accountability.
■ Exceptional value – our fees are typically 15–25% lower than equivalent London practices.
