How a project moves from appointing a licensed assessor through registration, assessment and quality assurance to a certification decision, and why the order matters.
BREEAM, a registered trade mark of BRE, follows a staged assessment and certification process rather than allowing a project to declare its own rating. The scheme presents five published steps: find a licensed assessor, register the project, undertake the assessment, undergo a quality assurance check and receive certification. Each stage has a different purpose, and the responsibilities of the project team, the assessor and the certification body remain distinct throughout.
The first stage is the appointment of a licensed assessor. The assessor establishes the applicable standard, version, territory, building sector and lifecycle stage, then manages the formal assessment route. Appointment does not transfer responsibility for designing or constructing the asset to the assessor. It establishes the qualified and licensed person who will interpret the method, review the evidence and submit the assessment for certification.
The second stage is registration. Registration creates the formal assessment record and links the asset to a defined scheme, version, scope and organisation. The third stage is the assessment itself, during which the project team produces the relevant design, construction or operational evidence and the assessor decides whether that evidence demonstrates the applicable requirements.
The fourth stage is quality assurance. The assessment submission is reviewed through the certification body's audit process rather than accepted solely on the assessor's declaration. The fifth stage is certification, which follows a successful quality assurance outcome. These stages are sequential because each depends on information and decisions established earlier in the process.
Registration is more than the allocation of a reference number. For a current new-construction registration, the required asset details include the country, the first address line, the town or city, the asset name, the asset lifecycle stage and the organisation associated with the asset. Those details establish what is being assessed, where it is located and which organisational record holds the asset.
The country is material because the international method may apply country-specific weightings and recognised local standards. The address and asset name distinguish the project from other developments and later appear in the assessment record. The lifecycle stage identifies whether the assessment concerns design, construction, operation or another defined point within the applicable standard.
The organisation field establishes the owner or organisational context within the assessment platform. It does not by itself prove ownership in a wider legal sense, but it determines how the asset is held and managed within the scheme's administrative system. Incomplete or inaccurate registration information can create confusion later when the assessment boundary, certificate wording or public listing is checked.
The project team creates the building and generates most of the underlying evidence. The client sets the project brief and rating objective. Designers prepare drawings, specifications, calculations and strategies. Contractors provide installation records, product information, site evidence and commissioning documentation. Specialists contribute reports in their own technical fields, while facilities personnel may provide operational information and handover records.
The project team is also responsible for making the decisions on which credits depend. The assessor can explain the method and identify the evidence expected, but cannot substitute for a missing design decision, an omitted survey, an unperformed calculation or an unrecorded construction activity. The assessment follows the project; it does not recreate the project after the event.
This division is particularly important when sustainability is treated as a separate reporting exercise. The scheme is integrated into design and delivery because many assessment outcomes arise from decisions about form, systems, materials, commissioning, management and operation. Evidence can demonstrate those decisions, but it cannot manufacture them where they never occurred.
The assessor manages the formal assessment and applies the relevant technical method. This involves confirming the appropriate scheme and version, reviewing the scope, advising on the assessment process, examining evidence, determining whether claimed performance is demonstrated and preparing the submission for quality assurance.
The assessor does not award the final certificate. The assessor reaches professional assessment judgements and submits the evidence and report through the controlled process. Those judgements must be supported by clear references, assessor commentary and records showing how the applicable requirements have been met.
The assessor also acts as the main formal link between the project and the certification process. Questions about interpretation, applicability and evidence are channelled through the assessor, who is responsible for presenting a coherent assessment. This role requires independence of judgement even where the assessor has been appointed and paid by the project client.
The certification decision belongs to BRE Global Ltd, not to the assessor. The certification body uses the licensed assessor's submission and supporting evidence to determine whether the assessment has successfully passed quality assurance and whether a certificate can be issued.
This separation protects the distinction between assessment and certification. The assessor evaluates the project against the method and submits the result. The certification body audits that work and makes the certification decision. A project team cannot convert an assessor's preliminary score, design review or internal forecast into a certified rating without completing the quality assurance stage.
BRE Global Ltd is accredited by the United Kingdom Accreditation Service against BS EN ISO/IEC 17065:2012 for the relevant certification activities and aligns its scheme-related activities to ISO 9001. The certification decision therefore sits within a formal third-party assurance framework rather than within the commercial relationship between the project and its assessor.
Quality assurance checks whether the assessment has been carried out in accordance with the applicable method and whether the claimed result is supported by suitable evidence. The audit can examine the assessor's interpretation, evidence references, calculations, scope and treatment of the rating requirements.
An audit may identify non-conformities, requests for clarification or evidence gaps. The assessor then coordinates the response, drawing on the project team where additional information is available. The presence of an audit query does not automatically mean that the project has failed, but the issue must be resolved before the relevant claim can be accepted.
The quality assurance stage is not intended to redesign the project. It tests the submitted assessment. If a design choice was not made, a product was not installed or a required activity did not occur, the audit cannot turn a later explanation into the missing outcome. The strength of the submission depends on the strength and timing of the project evidence.
Many assessment requirements are tied to particular project stages. An early strategy may need to influence the brief. A survey may have to occur before site work disturbs existing conditions. A design analysis may need to inform options before one solution is fixed. Construction records may need to be produced while work is visible. Commissioning evidence must relate to the installed systems.
A decision made late in design cannot always be evidenced as though it had informed the earlier process. A retrospective minute cannot prove that an option was considered at the required time, and a post-completion photograph cannot necessarily demonstrate concealed construction. The evidence must correspond to the real sequence of project decisions and activities.
This is why late appointment creates risk. The assessor may identify credits that remain achievable, but cannot guarantee recovery of opportunities that depended on an earlier stage. A project can still be assessed, yet its available evidence and final rating may be constrained by decisions already taken.
A design-stage assessment reviews the proposed building and the commitments made through the design information available at that time. It can produce an interim certificate where the applicable process permits, but it remains dependent on later delivery.
The post-construction or final assessment examines the completed asset and confirms whether the design commitments were implemented. Specifications may need to be matched to installed products, proposed systems to commissioning results and management commitments to completed handover information.
The final outcome can differ from the design-stage forecast. Some credits may be secured through stronger final evidence, while others may be lost through substitutions, omitted records or changes in scope. The later assessment is not a clerical update; it is a review of what was actually delivered.
The registered asset details and assessment scope influence the eventual certificate. Country, address, asset name, lifecycle stage and organisation help identify the subject of certification. The standard, version and boundary determine what the rating covers.
A certificate for one tenant area does not certify an entire building. A certificate at design stage does not state that construction has been completed in accordance with every commitment. A certificate for an existing asset does not automatically extend to later refurbishment. Accurate registration and scope control are therefore essential to accurate public claims.
Changes to the project name, address, owner, boundary or lifecycle stage should be managed through the appropriate scheme process. Informal changes within project documents do not automatically alter the formal assessment record.
Certification is the final step, not the starting assumption. The certificate records the outcome reached after registration, assessment and quality assurance. It states the defined asset and assessment information and presents the rating achieved under the applicable method.
The process does not allow a project team to self-certify, and it does not allow an assessor to issue the certification mark independently. The project team supplies and creates the evidence, the licensed assessor validates and submits the assessment, and BRE Global Ltd makes the certification decision.
The sequence is therefore both administrative and technical. Early decisions create the potential for performance, records preserve the evidence, assessment tests the claims, quality assurance checks the assessment and certification confirms the accepted result. Where a necessary decision was not taken at the required stage, the process cannot safely treat a later reconstruction as equivalent to contemporaneous evidence.
The project team creates the evidence, the licensed assessor validates and submits the assessment, and the certification body decides.
Country, address, asset name, lifecycle stage and organisation together establish exactly what is being assessed.
Each stage depends on information settled earlier, so retrospective records rarely substitute for contemporaneous ones.
BRE publishes five steps: find a licensed assessor, register the project, undertake the assessment, undergo a quality assurance check, and receive certification.
The certification decision belongs to BRE Global Ltd. A licensed assessor prepares and submits the assessment, and the certification mark is issued by BRE Global Ltd after the quality audit.
Registration requires the country, the address, the asset name, the asset lifecycle stage and the organisation associated with the asset.
