BREEAM pre-assessment at planning: which credits matter
A BREEAM pre-assessment is a licensed assessor's estimate that the scheme as drawn can hit the required rating. Several credits are locked by the planning drawings and cannot be recovered later.
A BREEAM pre-assessment submitted with a planning application is a licensed assessor's estimate that the scheme as drawn can reach the rating your local plan asks for, usually Excellent for new non-residential floorspace. It is not a certificate and it commits nobody. What makes it worth doing properly is that a handful of credits are decided by choices you lock in before you submit, and those credits cannot be recovered later by specifying better carpet.
The pre-assessment is a design tool disguised as a planning document. Treat it as the second one and you will end up with a condition you cannot discharge.
What the pre-assessment is for
Local plan policies that require BREEAM typically ask for a stated rating and evidence at application stage that it is achievable. The pre-assessment supplies the evidence: a credit-by-credit tracker showing which credits are targeted, which are likely, which are excluded and what the resulting score is, with a margin above the threshold.
Officers read three things. The headline percentage. The margin, because a scheme sitting one credit above a threshold will fall below it during value engineering. And the mandatory minimum standards, because those are pass or fail regardless of the total.
A BREEAM Pre-Assessment has to be prepared or signed by a licensed assessor to carry weight. This is one of the report types where councils expect a suitably qualified author, and professional review is strongly advised before anything is submitted.
Ratings and why minimum standards bite
Recent versions of BREEAM UK New Construction have set the rating benchmarks at 30, 45, 55, 70 and 85 per cent for Pass, Good, Very Good, Excellent and Outstanding. Verify the benchmarks for the version your local plan cites, because BREEAM is revised periodically and policies sometimes name an older scheme version.
The part that catches teams out is the minimum standards. Each rating carries compulsory credits in specific issues, so a scheme cannot assemble Excellent purely from the low-cost credits in easy sections. Energy performance, water consumption, construction waste and commissioning all carry minimum requirements that rise with the rating. A tracker showing 71 per cent with a minimum standard unmet is not an Excellent scheme.
Percentages are also weighted by section, so a credit in energy is worth more than a credit in an unweighted category. When you are trading credits during design, trade by weighted contribution.
Scope matters as well. BREEAM UK New Construction is the usual route for new buildings, with separate schemes for refurbishment and fit-out and for infrastructure. A shell and core office assessed under the wrong scheme produces a tracker that looks fine and satisfies nobody, so state the assessment route and the assessed floorspace on the first page.
Credits fixed before you submit
These are the ones to concentrate on at planning stage, because the planning application fixes them.
Energy performance is driven by form factor, orientation, glazing ratio and fabric. The massing on your drawings sets the ceiling for this section, and it is the heaviest weighted section in the scheme. A deep plan with high glazing on a west elevation costs energy credits and overheating credits at the same time.
Land use and ecology credits reward appointing an ecologist early, surveying before design is fixed, retaining existing features and enhancing the site. Appoint late and the early-appointment credits are simply gone. There is a direct overlap with mandatory biodiversity net gain here, so one ecological appraisal can feed both, provided the brief covers both.
Pollution credits covering surface water run-off depend on the drainage strategy and on attenuation you can actually fit on the site. Once the layout is consented, adding storage is expensive.
Transport credits depend on where the building is and what you provide: public transport accessibility, cycle parking numbers, showers and changing facilities. Cycle store locations belong on the planning drawings.
Health and wellbeing credits for daylight and view out depend on floor-to-ceiling heights, window head heights and plan depth. Again, drawings.
Materials credits reward a life cycle assessment of the structure and envelope carried out early enough to influence options. That is the same exercise as a Whole Life Carbon Assessment, so commission one piece of work rather than two.
Where it meets the energy statement
The BREEAM tracker and the energy strategy have to tell the same story. If the Energy Statement claims a percentage improvement over Part L notional that the BREEAM energy credits do not reflect, an officer or a consultee will notice, and the inconsistency undermines both.
In London the energy hierarchy of be lean, be clean, be green and be seen structures the energy case, and the London Plan requires monitoring after completion. Elsewhere the local plan sets its own improvement target. Either way, run the Part L calculation first and let the BREEAM energy credits follow it, not the reverse.
The wider narrative belongs in a Sustainability Statement, which is where the pre-assessment, the energy strategy, water efficiency and circular economy commitments get tied together into something an officer can quote in a report.
Getting the condition wording right
Most BREEAM policies land as a condition. Poorly worded conditions cause more grief than the assessment.
Watch for four things:
- Whether the condition requires a design stage certificate before development starts or merely a report. A certificate takes time to issue, so a requirement tied to the start of works needs programming.
- Whether the post-construction certificate deadline is realistic. Six months after occupation is common and workable. Anything shorter is not.
- Whether the condition names a specific BREEAM version. If it names a version that has been superseded by the time you build, you need a variation.
- Whether the condition applies to the whole development or to defined parts, which matters on mixed-use schemes where residential floorspace is assessed under a different route.
If any of those look wrong, raise them before the decision is issued. Varying a condition afterwards means a section 73 application, a fee and eight weeks.
Ask also who is expected to submit the certificate. On a development sold on after consent, a condition drafted around the applicant rather than the owner for the time being creates an argument nobody needs at the point of occupation.
Where pre-assessments fall over
The recurring failure is optimism about credits that depend on a contractor who has not been appointed. Site management credits, considerate construction, waste diversion rates and commissioning all sit with a builder, and pricing a pre-assessment on best-case contractor performance leaves no margin.
The second is the innovation credits. They are useful for headroom, but they usually require an approved innovation route or an exemplary level performance, and counting them at planning stage to reach a threshold is asking for trouble.
The third is fabric performance assumed at values the specification will not survive. Overheating is the visible symptom, which is why an Overheating Risk Assessment under CIBSE TM59 or the Part O methodology often exposes an energy strategy that only worked on paper.
Illustrative example: a three-storey office of 2,400 m2 targeting Excellent. The tracker shows 71.4 per cent, with two innovation credits and a health credit for daylight in a plan 18 metres deep. Strip out the innovation credits and rerun the daylight modelling honestly, and the scheme sits at Very Good. Better to find that before the condition is drafted than after.
This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
Does a BREEAM pre-assessment have to be done by a licensed assessor?
To carry weight, yes. Councils expect the tracker to be prepared or signed by a licensed BREEAM assessor, because the scoring depends on how each issue is interpreted and evidenced. An unsigned tracker is treated as an aspiration rather than evidence, and it will not satisfy a policy that asks for demonstrated achievability at application stage.
What rating do councils usually require?
Excellent is the common requirement for new non-residential floorspace in adopted local plans, with Very Good sometimes accepted for refurbishment or smaller schemes. The requirement sits in the local plan or a sustainability supplementary planning document, so check the adopted policy wording rather than assuming a standard figure applies.
How much headroom should the tracker show?
Enough to survive value engineering and a change of contractor. A scheme sitting one or two credits above a rating threshold will usually drop below it during design development, particularly where the margin depends on innovation credits or on site management credits that a builder has not yet committed to.
Can BREEAM and biodiversity net gain use the same ecology work?
Largely, provided the ecologist is briefed for both at the outset. The land use and ecology credits reward early appointment, survey before design is fixed and measurable enhancement, which overlaps with the habitat baseline and post-development calculation required under the Environment Act 2021 regime. Two separate late appointments waste money and lose the early credits.
What happens if the BREEAM version is superseded before we build?
If the condition names a specific scheme version, you need it varied, normally by a section 73 application. Ask for wording that refers to the scheme in force at the time of registration, or to the rating rather than the version, before the decision notice is issued. Fixing it afterwards costs a fee and around eight weeks.
