UK Sustainability Consultancy for Whole Life Carbon, BREEAM & Net Zero Buildings

We deliver BREEAM assessments across all major building types, from commercial and education buildings to residential schemes and large mixed‑use developments. Our team has extensive experience achieving BREEAM Outstanding and Excellent ratings, leveraging early‑stage feasibility work, pre‑assessments and strategic design input to secure cost‑effective, regulatory‑aligned outcomes.

We assess the environmental impact of buildings, products, and processes from cradle to grave. Our Life Cycle Assessment work forms the backbone of Environmental Product Declarations (EPDs), supporting both manufacturers and project teams with clean, defensible numbers for low‑carbon specification. We provide full LCA modelling, supply‑chain data capture, and alignment with EN 15804, ISO 14025, and ISO 21930 standards.

CarbonCentric is our proprietary carbon‑management platform designed to deliver real‑time embodied‑carbon insight across construction supply chains. Used on live projects, CarbonCentric has achieved:

• 323 kg CO₂e/m² average carbon saved across completed projects

• Real‑time dashboarding, interactive A4 emissions maps, subcontractor logins and transparent data capture
  

This allows smarter, earlier carbon reductions and stronger project compliance.

Mainer creates, verifies and publishes EPDs for manufacturers and product suppliers. Our team manages LCA modelling, data onboarding, background reporting, third‑party verification and programme‑operator publication - ensuring full compliance and market credibility. EPDs are supported by strong supply‑chain engagement and manufacturing data capture to ensure robust, high‑quality results.

We help organisations embed environmental and social governance into their operations and development strategies. Our ESG support aligns businesses with modern sustainability expectations - strengthening resilience, stakeholder confidence and long‑term value creation.

Mainer assesses and guides developments towards Fitwel certification - enhancing occupant health, wellbeing and social value through evidence‑based design and operational strategies. Our expertise supports clients aiming to build healthier, future‑ready environments.

We assess potential environmental impacts of development proposals and support clients through the planning process. Our EIA work ensures developments minimise environmental harm and meet regulatory expectations for responsible, sustainable delivery.

We prepare robust planning statements that communicate a development’s sustainability credentials - supporting approval, compliance and stakeholder engagement. Our team ensures sustainability is integrated meaningfully into planning submissions and supported with the required evidence.
