What a licensed BREEAM assessor is allowed to do

A BREEAM rating cannot be awarded by anyone who has not been licensed to award it. That is the single fact that changes how you plan a project with a BREEAM condition attached. A sustainability consultant can advise on which credits are achievable, model the energy, write the strategy and sit in the design team meetings. Only a licensed assessor, licensed by BRE for the specific scheme and version in use, can carry out the assessment and submit it for certification.

So the question "who writes the BREEAM report" has two different answers depending on which report you mean. The pre-assessment that goes in with the planning application and the certified assessment that discharges the condition are different exercises with different competence requirements.

Why assessment is a licensed activity

BREEAM is a proprietary assessment method operated by BRE, not a statutory standard. The rating has value because the method is applied consistently and because BRE quality-assures the evidence behind every certificate before it is issued. That consistency depends on controlling who performs the assessment.

A licence is therefore a contractual permission from the scheme operator rather than a statutory qualification. An assessor completes training on a specific scheme and version, passes the examination, holds the licence through an organisation registered with BRE, and maintains it through continuing requirements set by the operator. The licence can be withdrawn.

The consequence for a project team is that the assessor has obligations to the scheme operator as well as to the client. They are not free to award a credit because the design team believes it has been met. The evidence has to meet the requirements in the scheme manual, and BRE's quality assurance will test it.

Scheme versions and assessor licences

Licences are specific. An assessor licensed for one scheme is not automatically licensed for another, and an assessor licensed for an earlier version of a scheme is not automatically licensed for the current one.

The scheme families that matter for UK planning work are new construction, refurbishment and fit-out, in-use for existing operational buildings, and the community-scale scheme used on large masterplans. A planning condition requiring "BREEAM Excellent" without naming the scheme and version is ambiguous, and that ambiguity surfaces years later when the condition is discharged against a version that no longer exists.

Two practical steps remove most of that risk. When a condition is drafted, ask for the scheme family and the version in force at the date of the building control application, or wording that allows the version current at the time of registration. And when you appoint, confirm in writing that the individual holds a current licence for that scheme and version, not simply that the firm has assessors.

There is a second, separate role. A BREEAM Accredited Professional is a credit-earning role within some schemes, held by someone trained to facilitate the assessment process from early design. It is not the same as being a licensed assessor, and one person can hold both. The credit is awarded for the process, not for the person's presence on a drawing.

Pre-assessment against formal certification

This is where most planning teams get caught, so it is worth being precise.

A BREEAM Pre-Assessment is the document a planning officer reads. It states the scheme and version, the target rating, a credit-by-credit tracker showing which credits are targeted, which are not, and the resulting score, plus the mandatory credit requirements for the target rating. Councils usually expect a suitably qualified author for it, and professional review is strongly advised even where the authority does not insist.

Formal certification runs in two stages. The design stage assessment is registered with BRE, assessed against the design information, and quality assured, producing an interim certificate. The post-construction stage reviews what was actually built and procured, and produces the final certificate. A design stage certificate is not a final rating, and a condition requiring a final certificate is not discharged by an interim one.

The role of the assessor at design and post construction stages

At design stage the assessor's job is to interrogate the design information against the scheme manual and to tell the team what evidence will be needed. Done properly, that happens early enough to change the design.

At post-construction stage the job changes character entirely. The assessor is auditing: checking that the specified products were installed, that the commissioning took place, that the site monitoring data exists, that the contractor's records support the management credits. Where evidence has not been collected during construction, it cannot be recreated afterwards, and credits are lost.

That asymmetry is the single most expensive feature of the process. A credit targeted at design stage and relied on in the planning score, but unsupported by construction records, drops out at post-construction and can take the rating below the level the planning condition required.

The mitigation is unglamorous. Put the evidence schedule into the contract documents, name the party responsible for each item, and have the assessor review evidence during construction rather than at the end.

Evidence the assessor will ask you for

The requests are consistent across projects, and knowing them in advance saves months.

• as-built drawings and specifications, with product references rather than performance descriptions
• the energy model output in the form the scheme requires, with the input assumptions
• commissioning records and the commissioning plan
• construction site monitoring data for energy, water, transport and waste
• the site waste records showing diversion from landfill by stream
• ecology, transport and acoustic reports where credits depend on them, prepared by the relevant specialists
• manufacturer certification for responsible sourcing of materials
• the building user guide and the aftercare commitments

Several of those depend on reports produced by other specialists, and a credit is only as secure as the specialist report behind it. An acoustic credit needs measurements by an acoustician. An ecology credit needs an ecologist's report and, in many cases, works carried out under their supervision.

Where a sustainability consultant is not an assessor

The distinction is easy to state and easy to blur in practice.

A sustainability consultant can run the options appraisal, model the energy and overheating performance, write the energy and sustainability narrative for the planning application, advise on which credits to target, coordinate the evidence and manage the team. None of that requires a BREEAM licence.

What requires the licence is performing the assessment, registering it, awarding credits, and submitting for certification. If a firm offers to "do your BREEAM" and cannot name the licensed individual and the scheme version, that is the question to ask.

Where a planning condition requires certification, a report written by an unlicensed consultant will not discharge it however good the analysis is. Where a planning policy only requires a pre-assessment demonstrating that a rating is achievable, a well-evidenced pre-assessment by a licensed assessor is the proportionate answer, and the formal registration can wait.

The professional directory is the route for finding a reviewer to check a draft before it goes in, and the report index shows how the pre-assessment sits alongside the energy and sustainability documents in a submission.

Appointing at the right stage

Appoint the assessor at concept design, before the structural grid and the services strategy are fixed.

The reason is specific rather than general. Several BREEAM credits are only available if a study is carried out before design decisions are made, and the manual sets out when. The site ecology and land use credits depend on survey information gathered before ground is disturbed. The management credits depend on stakeholder consultation and a project brief process that has to happen at the start. A commissioning credit depends on a commissioning plan and a named commissioning manager appointed early. These are not credits you can reach backwards for.

The sequence that works is: appoint at concept, pre-assessment at or before planning submission, register for the design stage assessment when the design is substantially fixed, evidence review during construction, post-construction assessment at completion. Where a planning condition sets a trigger point for the design stage certificate, usually before any above-ground works start, build that into the programme.

The practical test of whether you have appointed early enough is whether the assessor's first report changes the drawings. If it only records what has already been decided, the appointment came too late. Comparable competence questions for other specialist authors are covered in acoustician qualifications in planning and lighting designers and the guidance councils cite.

This is general guidance, not legal advice; check the position with your local planning authority, the scheme operator or a qualified professional before relying on it.
