Licensed BREEAM assessors and what the licence covers

A BREEAM rating can only be awarded through an assessment carried out by an assessor licensed by BRE for the relevant scheme and version, and certified by BRE afterwards. No amount of design work by the project team produces a rating on its own. That is the whole point of the licence: BREEAM is a certification scheme, and the certificate comes from the scheme operator rather than from the design team or the council.

For an architect this has a practical consequence. If a planning condition says the development shall achieve BREEAM Excellent, the client is signed up to a certification process with its own timetable, its own evidence requirements and its own fees, running from early design through to twelve months after practical completion in some schemes.

Why BREEAM work requires a licensed assessor

Assessors train on a specific scheme, sit an examination, and hold a licence tied to that scheme and version. BREEAM UK New Construction, Refurbishment and Fit-Out, and In-Use are separate schemes with separate licences, so an assessor licensed for one is not automatically able to certify under another.

The assessor gathers the evidence, applies the technical manual, scores the credits and submits the assessment to BRE for quality assurance. BRE checks a sample of the evidence and issues the certificate. That external check is what gives a BREEAM rating its currency with planning authorities, and it is why councils write conditions requiring a certificate rather than a report.

There is a second role worth knowing about. A BREEAM Accredited Professional is a separate accreditation held by a member of the design team whose involvement in setting and tracking performance targets can itself earn credits. The two roles are distinct, and one person can hold both.

What a pre-assessment can and cannot say

A pre-assessment estimates the credits the scheme is likely to achieve, identifies which are at risk, and shows whether the target rating is realistic. It is a planning and design tool. It does not confer a rating and cannot be quoted as one.

Councils know this. A well-drafted condition asks for a design stage certificate before commencement or before a specified stage, and a post-construction certificate before occupation, with the pre-assessment merely demonstrating at application stage that the target is achievable. A BREEAM Pre-Assessment submitted with the application should therefore be honest about the credits that depend on decisions not yet made.

The useful content in a pre-assessment is the risk register: which credits are secure, which are contingent on a specification the client has not yet agreed, and which are unavailable because of the site. Ecology credits on a hard-surfaced urban plot, transport credits on a site with poor public transport access, and land use credits on greenfield are the usual casualties.

Because certification depends on a licensed assessor, a pre-assessment drafted from structured project data should be treated as a starting point for that assessor rather than as the assessment itself. Councils expect a suitably qualified author, and professional review is strongly advised before anything is submitted.

Design stage against post-construction certification

Two certificates, two moments, two sets of evidence.

The design stage assessment is based on drawings, specifications, calculations and commitments. It produces an interim certificate showing the rating the design is expected to achieve. It is usually the certificate a pre-commencement planning condition asks for.

The post-construction assessment verifies what was actually built. Site records, commissioning results, as-built drawings, product data sheets and photographic evidence all feed in, and credits claimed at design stage can be lost if the specification changed on site. Value engineering after the design stage certificate is the single most common cause of a dropped rating.

Between the two, the assessor needs a route to the information. Agree at the outset who collects site evidence, in what format, and when. Chasing a subcontractor for commissioning records eighteen months after they left site is a poor use of anyone's time.

Where planning conditions reference a rating

Many adopted local plans require a BREEAM rating for non-residential development above a floorspace threshold, and London boroughs apply the sustainable design policies in the London Plan alongside their own. The thresholds and the required rating vary, so read the adopted plan and any supplementary planning document rather than assuming Excellent is the standard everywhere.

Read the condition wording closely too. There is a real difference between a condition requiring the development to achieve a rating, one requiring evidence that it has been designed to achieve it, and one requiring a certificate to be submitted. The first is the hardest to discharge and the one most likely to cause a problem at sale, because the certificate has to exist before the condition is satisfied.

Where the local plan requires an energy hierarchy calculation as well, that sits in the Energy Statement rather than in the BREEAM assessment, though the two share inputs and should be prepared by teams talking to each other.

Appointing early enough to influence credits

Some credits are only available if the assessor is involved from the start. Credits relating to the project brief and design process depend on stakeholder consultation and performance targets being set at the right RIBA stages, with evidence of when it happened. Appoint the assessor at stage 4 and those credits are gone, permanently, whatever the building turns out to be like.

A workable sequence:

1. Appoint the assessor at concept design and register the project on the relevant scheme.
2. Run a credit workshop with the full design team to agree the target rating and the credit strategy.
3. Set the mandatory minimum standards for the target rating as fixed requirements in the specification.
4. Track the credit position at each design stage and re-test after any value engineering exercise.
5. Submit for design stage certification in time to discharge the planning condition.
6. Collect site evidence continuously through construction for the post-construction assessment.

Mandatory minimum standards are the trap in step three. Higher ratings carry compulsory minimum performance in specific issues, so a scheme can hold enough credits on paper and still fail to reach the rating because one mandatory item was missed.

Evidence the assessor will ask you for

Expect requests for the energy model outputs and the compliance calculation, drainage and flood risk information, an ecology report and the ecologist's recommendations, acoustic testing results or a design-stage acoustic report, water consumption calculations, responsible sourcing certificates for the main materials, construction site waste records, commissioning plans, and a thermal comfort analysis.

Most of that already exists somewhere in the project. The assessor's difficulty is usually not that the evidence is missing but that it is scattered, undated, or in a form that does not show what the technical manual requires. Setting up a single evidence folder at registration, named by credit reference, saves a great deal of time later.

If you need a reviewer with the right licence to check a draft before it goes anywhere near a planning submission, the professional directory is the route to a sign-off, and the report pages set out which documents typically sit alongside a sustainability submission.
