Reduce Carbon. Achieve Compliance. Optimise Building Performance.
Life Cycle Assessments (LCA) & Whole Life Carbon (WLC) Assessments
We deliver Life Cycle Assessment (LCA) and Whole Life Carbon (WLC) Assessments for developments across the UK, helping clients meet planning requirements, achieve BREEAM credits, and reduce embodied carbon from concept to completion.
What is Life Cycle Assessment (LCA)?
A Life Cycle Assessment (LCA) in construction measures the total environmental impact of a building across its entire lifespan - from raw material extraction to demolition.
This includes:
A1–A3: Material production (embodied carbon)
A4–A5: Transport and construction
B1–B7: Use phase (maintenance, energy, water)
C1–C4: End-of-life (demolition, disposal)
LCA provides a data-driven understanding of carbon hotspots, enabling better design decisions and lower environmental impact.
What is Whole Life Carbon (WLC)?
Whole Life Carbon (WLC) expands LCA to focus specifically on carbon emissions across all life cycle stages.
It is now a core requirement for planning in London and increasingly across the UK.
When Do You Need an LCA?
You may require an LCA or WLC assessment for:
Planning applications (GLA / London Plan)
BREEAM certification (Mat 01 credits)
Net zero carbon strategies
Sustainability reporting and ESG targets
Material optimisation and cost reduction
Early-stage LCA delivers the greatest value by identifying high-impact carbon reductions before design is fixed.

Frequently Asked Questions
-
Costs vary depending on project size and stage, but early-stage assessments are typically more cost-effective and deliver greater savings.
-
Yes - particularly in London, where Whole Life Carbon assessments are required under the London Plan.
-
LCA measures environmental impacts broadly, while WLC focuses specifically on carbon emissions across the life cycle.
-
Most assessments take between 2-6 weeks depending on project complexity and available data.
