The Scope of BREEAM Consultancy in London
In London, BREEAM consultants are typically involved from early project stages, where sustainability targets must be aligned with site constraints, planning policy, and cost planning. Early engagement is particularly important for refurbishment projects, high-density sites, and developments with ambitious carbon and energy performance objectives.
Throughout design and construction, BREEAM consultants coordinate with multidisciplinary teams to manage energy and water strategies, materials and responsible sourcing credits, construction environmental management, and post-completion evidence submission. Strong familiarity with local authority expectations and complex stakeholder coordination is essential for successful BREEAM delivery in the London market.
