A BREEAM pre-assessment is an early, informal scoring exercise that estimates the BREEAM rating a proposed building can realistically achieve — before you register the project for formal assessment and before the design is locked in. It answers one question every developer facing a BREEAM planning condition needs answered: can this scheme actually hit the rating the council is asking for, and what will it take?
This guide explains when a pre-assessment is needed, what it contains, what it does not do, and how it fits into a UK planning application. It is the starting point of our ten-part BREEAM pre-assessment series — the other posts cover costs, planning conditions, the category checklist and more.
What is a BREEAM pre-assessment?
BREEAM (Building Research Establishment Environmental Assessment Method) scores a building across ten categories — management, health and wellbeing, energy, transport, water, materials, waste, land use and ecology, pollution, and innovation — and awards a rating from Pass to Outstanding. The scheme is operated by BRE and certification can only be issued through a licensed assessor.
A pre-assessment sits before all of that. Working from drawings, the site context and the emerging specification, the reviewer walks through the credit list, marks each credit as achieved, achievable or unlikely, and totals a projected score. The output is typically a credit tracker and a short report saying, for example: “the scheme currently projects 58% — Very Good — with a realistic route to 71% if the following six credits are secured.”
When do you need a BREEAM pre-assessment?
Four situations account for nearly all pre-assessments in the UK:
- A planning policy or condition requires a BREEAM rating. Many local plans require major non-residential schemes to achieve BREEAM Very Good or Excellent, and councils increasingly ask for a pre-assessment with the application as evidence the target is deliverable. Our guide to BREEAM in planning covers who asks and why.
- A funder, tenant or public-sector client requires it. Government bodies and institutional investors commonly set BREEAM Excellent as a procurement or ESG requirement.
- You need to fix the target before design freeze. Many credits — ecology, transport, some materials choices — are decided by decisions made at concept stage and cannot be recovered later.
- You want a cost picture early. The gap between Very Good and Excellent can carry real capital cost; a pre-assessment quantifies the cheapest route before contracts are let.
What does a pre-assessment include?
- A credit-by-credit review against the current scheme manual — from 2026 registrations that generally means BREEAM Version 7;
- A projected score and rating, with the buffer above the threshold made explicit;
- A list of mandatory minimum standards for the target rating — credits you cannot trade away;
- Actions by discipline: what the architect, services engineer and landscape designer each need to secure;
- Risks: credits assumed but not yet evidenced.
What a pre-assessment is not
A pre-assessment is not a certificate and carries no formal status with BRE. It does not register the project, and its score is not independently verified — which is why councils usually condition the certified rating, not the pre-assessment. The differences are set out in pre-assessment vs full assessment. Think of it the way a daylight feasibility screen relates to a full BRE 209 report: cheap, fast, and decisive about whether the expensive step will succeed.
How much does it cost and how long does it take?
Indicative UK market figures put a pre-assessment between roughly £500 and £3,000 depending on building size, complexity and the target rating — a small fraction of full certification. Simple schemes are usually turned around in one to two weeks. Full figures and cost drivers are in our BREEAM pre-assessment cost guide.
Frequently asked questions
Is a BREEAM pre-assessment mandatory?
No national rule requires one. It becomes effectively mandatory when a local validation list asks for it with the application, or when a planning condition requires you to demonstrate a deliverable route to the target rating.
Who can carry one out?
Anyone competent in the scheme can produce an informal pre-assessment; only a licensed assessor can register and certify the project. If certification will follow, involving the eventual assessor early avoids re-scoring.
Does a good pre-assessment guarantee the rating?
No. It projects a score from design intent. Credits are only banked when evidence is verified at design stage and post-construction review — which is why a sensible pre-assessment targets a few percentage points above the threshold. See picking a realistic target.
Key takeaways
- A BREEAM pre-assessment is an early, informal estimate of your achievable BREEAM rating — not a certificate.
- Commission one when a council, funder or client sets a BREEAM target, ideally before design freeze — see when to commission.
- Expect a credit tracker, a projected score with buffer, mandatory minimum standards and actions by discipline.
- Indicative cost is roughly £500–£3,000; simple schemes take days, not months.
- Ratings run Pass (30%), Good (45%), Very Good (55%), Excellent (70%), Outstanding (85%).
