Products and services

• M&E Services Design Full mechanical and electrical (M&E) services design from concept through construction to commissioning and handover, covering residential, commercial, educational, healthcare, leisure, sport, and transportation sectors. Delivered for property developers and contractors as the firm's core engineering consultancy offering.
• Sustainability Services Energy Audits, Energy Statements, EPC, SAP, and SBEM calculations with a focus on air source and ground source heat pumps for energy-efficient building design. Supports regulatory compliance and sustainability outcomes for construction projects.
• REVIT 3D Modeling 3D BIM modeling using Autodesk Revit for services coordination, clash detection, pressure drop calculations on pipes and ducts, and cable sizing, designed to reduce abortive work and construction costs. Provided at every stage of design.
• IES Virtual Environment Thermal Modeling Dynamic simulations, peak load calculations, energy consumption estimation, overheating analysis, and Part L compliance checks (SBEM) using IES Virtual Environment software for accurate plant sizing based on realistic diversity factors, occupancy levels, and weather conditions.
• Digital Twin and Building Scanning Services Detailed 3D laser scanning (digital twin) of existing buildings combined with Building Management System (BMS) and CMMS software integration for building maintenance and management, designed to reduce operational costs over the building lifecycle.
• Commissioning Validation Commissioning validation and supervision services for building services systems, following industry standards and guidance such as CIBSE Commissioning Code A and Code M.
• Condition Surveys and Building Evaluation Condition surveys, pre-acquisition surveys, and building evaluation services for existing structures to inform renovation, refurbishment, or acquisition decisions.
• Acoustic Engineering Acoustic engineering and testing services for building projects to address sound insulation, noise control, and acoustic performance requirements.
• AI-Assisted Design Artificial intelligence integration for spatial planning, data collection, design library access, and automatic modification of standard system configurations based on multiple parameters in the design and construction process.

Broad incumbents

• WSP Global: Global professional services consultancy with extensive building services/MEP engineering practice; competes across the same UK and European sectors as PIRSA but at vastly larger scale and broader service scope.
• AECOM: Global infrastructure consulting firm with major building engineering practice; competes with PIRSA on UK commercial, healthcare, and rail/transportation MEP design engagements as a large multi-discipline incumbent.
• Buro Happold: Global engineering consultancy with significant MEP/building services practice alongside structural and specialist engineering; competes with PIRSA on UK commercial and infrastructure projects but offers much broader service portfolio.
• Arup: Global engineering consultancy with established building services design practice; overlaps with PIRSA in MEP design for high-profile London and European projects but operates at vastly greater scale and discipline breadth.
• Mott MacDonald: Global engineering consultancy with significant UK building services and MEP design capability; competes for large-scale commercial, healthcare, and transportation projects alongside PIRSA but as a multi-discipline incumbent.

Direct peers

• Hoare Lea: UK-based M&E/building services engineering consultancy with deep BIM and sustainability expertise, comparable to PIRSA in offering MEP design from concept through commissioning across commercial, residential, healthcare, and education sectors.
• Hilson Moran: London-based building services engineering consultancy providing MEP design, sustainability, and digital engineering services to commercial, residential, and mixed-use developers — a UK boutique directly comparable to PIRSA.
• Cundall: International multi-disciplinary engineering consultancy with strong UK presence in building services (MEP) design, sustainability, and BIM — directly comparable in service offering and client base to PIRSA.

Emerging players

• Atelier Ten: Specialist building services and sustainability engineering consultancy with strong BIM and environmental design focus; comparable boutique positioning to PIRSA in MEP and energy/sustainability design for high-performance buildings.

Regional players

• Meinhardt Group: International engineering consultancy with building services/MEP design capability across Asia, Middle East, and Europe; comparable in core service offering though primary footprint is outside PIRSA's UK/Europe focus.
