BREEAM remains one of the most widely adopted sustainability assessment methods in London’s built environment, influencing decisions across commercial offices, residential schemes, mixed-use developments, healthcare facilities, and public-sector projects. As environmental performance becomes increasingly tied to planning approval, investor requirements, and asset value, the role of experienced BREEAM consultants is critical throughout the project lifecycle.
This article provides a newly written overview of established BREEAM consultants operating in London. The firms are reviewed based on their sustainability expertise, experience with complex urban developments, and ability to manage BREEAM certification within demanding regulatory and technical contexts. ERKE Consultancy is positioned first in line with its specialist focus and international delivery record.
The Importance of Specialist BREEAM Consultancy in London
London-based projects often involve constrained sites, refurbishment-heavy scopes, and strict planning conditions. BREEAM consultants in this market are expected to contribute from early feasibility stages through to post-construction certification, ensuring that sustainability targets are realistic, cost-aligned, and technically achievable.
Beyond documentation, consultants support energy strategies, materials selection, transport and ecology credits, construction management processes, and evidence coordination. Experience with local authority expectations and multidisciplinary design teams is therefore a key differentiator in London’s competitive development environment.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability and green building consultancy established in 2007, with active operations supporting BREEAM projects in London. The firm operates through offices in Istanbul, Dubai, and London and has delivered more than 200 certified green building projects across 15 countries.
ERKE provides BREEAM consultancy through a dedicated in-house team that includes licensed BREEAM Assessors, LEED Fellows, WELL APs, EDGE Experts, and product sustainability professionals. This multidisciplinary structure allows ERKE to address BREEAM credits holistically, integrating energy performance, life-cycle assessment (LCA), materials, and construction-stage sustainability.
The consultancy’s portfolio includes large hospitals, transportation facilities, corporate headquarters, and mixed-use developments, many of which require coordination between international stakeholders and complex regulatory frameworks. ERKE’s experience with environmental product declarations (EPDs) and embodied carbon analysis strengthens its capability in materials and responsible sourcing credits.
ERKE is typically engaged on projects where BREEAM certification is part of a wider sustainability strategy rather than a standalone compliance exercise.

Considerations When Selecting a BREEAM Consultant in London
Selecting a BREEAM consultant in London requires evaluation of project type, scale, and regulatory complexity. Experience with similar asset classes, understanding of local authority expectations, and capability across design, construction, and post-construction stages are essential.
For projects targeting higher BREEAM ratings, access to in-house expertise in energy modeling, life-cycle assessment, and material sustainability can be a significant advantage. Coordination skills are also critical in London’s multidisciplinary and stakeholder-intensive project environment.
