BREEAM certification consultancy

Design-stage through post-construction

BREEAM is the world's leading sustainability assessment method for master planning, infrastructure, and buildings. Established in 1990 by the Building Research Establishment in the UK, it has certified over 600,000 buildings across more than 90 countries. ISG delivers both BREEAM UK and BREEAM International assessments.

Our London office provides direct access to the UK BREEAM ecosystem — BRE assessor networks, local planning requirements, and the Part L energy compliance landscape. Our Abu Dhabi office extends this capability to Middle Eastern projects where international developers and institutional investors require BREEAM alongside local certification systems.

• Pre-assessment and feasibility — early-stage BREEAM scoring to determine achievable rating and identify design priorities
• Design-stage assessment — interim certification confirming the design meets the target rating before construction begins
• Post-construction assessment — final certification based on as-built evidence, commissioning results, and building performance data
• BREEAM In-Use — operational assessment for existing buildings seeking to demonstrate ongoing sustainability performance

Ten categories, one comprehensive score

BREEAM assesses buildings across ten weighted categories: management, health and wellbeing, energy, transport, water, materials, waste, land use and ecology, pollution, and innovation. Each category is scored and weighted according to regional priorities — energy carries more weight in energy-intensive climates, while ecology is weighted higher in biodiverse regions.

ISG navigates the full BREEAM assessment process, from initial pre-assessment through to the final post-construction certificate. Our assessors coordinate with design teams to maximize credit capture while keeping the certification process aligned with project timelines and budgets. For projects requiring both BREEAM and a local system like Estidama or Al Sa'fat, we manage the overlap to avoid duplicated effort.
