What Mccann & Partners does

McCann & Partners is a UK building services engineering consultancy specializing in the design of mechanical, electrical, and public health (MEP) systems for new and existing buildings. Founded in 1955 and headquartered in Cardiff with offices in Bristol and Swansea, the firm operates across ten vertical sectors including commercial, education, healthcare, residential, heritage, aviation, public sector, arts, sports and leisure, and hotels. Its service portfolio is anchored in MEP design and extends into Building Information Modelling (BIM) under PAS 1192-2:2013, Dynamic Thermal Simulation using IES-VE, Energy Performance Certification (EPC) via iSBEM and SAP, Part L carbon compliance via SBEM, BREEAM Advisory Professional services, the Code for Sustainable Homes, and Net Zero Carbon advisory including embodied and whole-life carbon assessments. The firm's technical stack is built around widely adopted engineering and compliance software rather than proprietary platforms, with BIM-level interoperability and 3D design production treated as standard practice.

The firm operates a project-based professional services model, generating revenue through fees for engineering design, sustainability assessments, and compliance certification delivered directly to construction companies, property developers, architects, and building owners. Pricing is scope- and complexity-based and is not publicly disclosed. The go-to-market motion is sales-led and relationship-driven, relying on sector reputation, repeat engagement, and referrals within the UK construction and property development ecosystem rather than digital or transactional channels. The firm holds multiple regulated accreditations (BREEAM AP, SAP assessor) that gate entry to specific compliance-driven engagements. The firm employs approximately 40-60 staff (sources disagree between the team page and home page), is privately held as a partnership under UK law, and has no disclosed external investment, parent company, subsidiaries, or M&A activity. No patents, trademarks, awards, or third-party alliances are referenced in available sources.

Products and services

• Mechanical, Electrical & Public Health (MEP) Engineering Design Core building services consulting offering covering the design of mechanical, electrical, and public health engineering systems for buildings of all types, including heating, ventilation, air-conditioning, power distribution, lighting design, fire alarms, renewable energy systems, building management controls, and specialist ventilation. Serves construction companies, property developers, architects, and building owners across commercial, education, healthcare, residential, and other sectors.
• Building Information Modelling (BIM) A process for creating and managing information on construction projects across the project lifecycle, with all design information produced in 3D as standard practice. Working to PAS 1192-2:2013 and producing Employer Information Requirements (EIR) and BIM Execution Plans (BEP) for construction project teams.
• Dynamic Thermal Simulation Uses market-leading thermal simulation software (IES-VE) to model the thermal performance of buildings, optimizing design to achieve required thermal comfort levels while minimising energy consumption. Used to demonstrate Part L Building Regulations compliance.
• Energy Performance Certification (EPC) Accredited service producing Energy Performance Certificates (EPCs) for both domestic and non-domestic buildings, using iSBEM software for non-domestic buildings and approved SAP software for domestic buildings.
• Net Zero Carbon Services Full range of net zero carbon design services including low carbon technology assessments, renewable energy strategies, embodied carbon calculations, and whole life carbon assessments. Develops bespoke net zero carbon roadmaps and strategies for clients.
• Part L Carbon Compliance Provides Part L carbon compliance calculations for new and existing non-domestic buildings using SBEM (Simplified Building Energy Model) software, producing compliance reports for both Part L2A (new non-domestic) and Part L2B (existing non-domestic) buildings.
• BREEAM Advisory Professional BREEAM AP service providing expert advice on built environment sustainability, environmental design and environmental assessment. Facilitates design team efforts to achieve target BREEAM ratings with up to three credits available for early engagement.
• Code for Sustainable Homes Environmental assessment rating standard for measuring sustainability of new homes with levels 1-6, where Level 6 represents zero carbon homes. Provides two-stage certification process for design and as-built assessment.
• Green Support (BREEAM ancillary services) Sustainability support services including Building User Guides, Travel Plans, Recycled Content Assessment, Climate Change Adaptation Strategies, and Indoor Air Quality Plans for BREEAM compliance.

Broad incumbents

• WSP: Global professional services firm with a major UK building-services practice covering MEP, sustainability, BIM and net-zero carbon advisory. Competes with McCann on larger UK frameworks where scale, multi-discipline capability and international reach are decision drivers.
• BDP (Building Design Partnership): Large UK-headquartered interdisciplinary design practice covering architecture, MEP engineering, lighting and sustainability. Substantially larger and broader than McCann, but competes for the same building-services scopes on large commercial, healthcare and education projects.
• Mott MacDonald: Global engineering, management and development consultancy with a sizeable UK buildings MEP practice. Significant overlap on healthcare, education and commercial sectors as a tier-one framework competitor.
• AECOM: Global infrastructure consultancy with UK building engineering (MEP) and sustainability capabilities. Competes for large-scale UK projects and framework appointments that McCann cannot resource at its current size.
• Sweco UK: European engineering consultancy with a UK building services and sustainability practice. Competes for MEP and energy/sustainability advisory on commercial and public-sector projects across the UK.

Direct peers

• Cundall: Independent multi-disciplinary engineering consultancy with strong MEP, sustainability and BIM practices. Competes for similar architects/developers and offers comparable BREEAM and net-zero advisory services.
• Hoare Lea: UK-based MEP engineering consultancy delivering mechanical, electrical and public-health design across commercial, healthcare, education and heritage sectors. Direct competitor for the same client-base of architects, developers and contractors on building-services scopes.
• Waterman Group: UK engineering consultancy offering building services (MEP), structural and environmental design alongside sustainability advisory. Overlaps with McCann on multi-sector building-services design and BREEAM/energy compliance work.
• Ridge and Partners LLP: UK property and construction consultancy offering building services (MEP) engineering alongside project management and surveying. Comparable in scale and sector mix, with multi-office UK presence and a similarly broad vertical focus.
• Hilson Moran: Independent UK building-services consultancy providing MEP engineering, sustainability, BREEAM and energy consultancy. Closely comparable on service mix (MEP design + BREEAM advisory + Part L/EPC) and UK regional footprint.
