How to Become a BREEAM Assessor in the UK
BREEAM Assessors check how a building performs against BREEAM, the environmental rating scheme run by BRE. You collect evidence from design teams and contractors on energy, water, materials, ecology and wellbeing, score it against the scheme criteria, and submit the assessment to BRE for certification.
Most assessors come from a building services, architecture, surveying, energy assessment or environmental background. You then train with BRE for a specific scheme, such as New Construction or In-Use, pass the exam and hold a licence, usually while working for a sustainability or engineering consultancy.

How to become a BREEAM assessor in the UK
There is no school-leaver route straight into this job. You first need a grounding in construction or sustainability, often through a degree in building services engineering, architecture, environmental science or surveying, or several years in energy assessment or construction. You then complete BRE's assessor training for the scheme you want to work in, pass the exam and take out a licence. Check BRE's current entry criteria before booking, as they vary by scheme. Membership of a body such as CIBSE or CIOB helps your credibility.
- Build a construction or sustainability base first, for example a degree in building services, architecture or environmental science, or experience as an energy assessor or site engineer.
- Learn how BREEAM credits work by reading the free technical manuals on the BREEAM website for New Construction and In-Use.
- Look for assistant or graduate sustainability roles at consultancies that run BREEAM assessments, where you can support licensed assessors and learn evidence gathering.
- Check BRE's entry criteria for your chosen scheme, then book the assessor training and pass the exam.
- Take out your licence and complete your first assessments under a senior assessor's review, keeping tidy evidence trails for BRE quality checks.
- Add a second scheme, such as Refurbishment and Fit-out or Communities, or pair BREEAM with energy modelling to widen the work you can take on.
