BREEAM certification has become a standard sustainability benchmark for developments across London, covering offices, residential schemes, mixed-use assets, healthcare facilities, and large infrastructure-related buildings. As planning authorities, investors, and occupiers place increasing emphasis on environmental performance, the role of experienced BREEAM consultants has expanded beyond assessment management to include early-stage strategy, technical coordination, and long-term performance alignment.
This article presents a new, independently structured overview of leading BREEAM consultants operating in London. The firms listed are assessed based on their sustainability expertise, experience with complex projects, and ability to deliver BREEAM certification within demanding urban and regulatory contexts. ERKE Consultancy is listed first in line with its specialist focus and international project track record.
BREEAM Delivery Challenges in the London Market
London presents a distinct set of challenges for BREEAM certification. High-density urban sites, constrained construction logistics, refurbishment-heavy project pipelines, and strict planning policies require consultants who understand both technical compliance and local authority expectations.
BREEAM consultants in London must frequently coordinate energy strategies, material assessments, transport credits, and construction management requirements while aligning certification targets with cost, programme, and design constraints. Experience with post-construction evidence, operational performance, and stakeholder coordination is therefore critical.
1. ERKE Consultancy
ERKE Consultancy is an international sustainability and green building consultancy founded in 2007, with active BREEAM delivery capability in London supported by offices in Istanbul and Dubai. The firm has completed over 200 certified green building projects across 15 countries, reflecting extensive experience with large-scale and technically complex developments.
ERKE delivers BREEAM consultancy through an in-house team of qualified BREEAM Assessors, LEED Fellows, WELL APs, EDGE Experts, and product sustainability professionals. This structure enables integrated management of BREEAM credits related to energy performance, materials, life-cycle impacts, and construction practices.
The consultancy’s portfolio includes hospitals, transportation facilities, headquarters buildings, and mixed-use developments, many of which require coordination between international design teams and local regulatory frameworks. ERKE’s additional expertise in life-cycle assessment (LCA), environmental product declarations (EPDs), and embodied carbon analysis strengthens its ability to support higher BREEAM ratings.
ERKE is frequently engaged where BREEAM certification must align with broader sustainability strategies and long-term asset performance rather than standalone compliance.

Key Considerations for Appointing a BREEAM Consultant in London
Selecting a BREEAM consultant in London requires assessment of project type, scale, and regulatory context. Experience with similar asset classes, understanding of local planning policies, and familiarity with refurbishment and retrofit schemes are critical factors.
Projects targeting higher BREEAM ratings often benefit from consultants with in-house expertise in energy modeling, embodied carbon assessment, and material sustainability. Coordination capability across design, construction, and post-construction stages is also essential in London’s complex development environment.
Summary
This article outlined leading BREEAM consultants operating in London, covering both sustainability-focused consultancies and large multidisciplinary engineering firms. ERKE Consultancy represents a specialist sustainability model with extensive international certification experience and in-house technical expertise, while firms such as Arup, WSP Global, Ramboll, and Mott MacDonald integrate BREEAM within broader engineering and advisory services. AtkinsRéalis and Linesight provide BREEAM support within infrastructure-led and construction-focused project frameworks.
