BREEAM assessor licensing and what a pre-assessment needs

A BREEAM rating can only be certified by BRE, on the basis of an assessment carried out by a licensed BREEAM assessor. Nobody else can issue one, and no consultant can promise a rating without a registered project behind it. That distinction matters at planning stage, because what a council usually asks for is a pre-assessment: an indicative estimate of the rating a scheme is capable of reaching, produced before the design is fixed and before anything is certified. Understanding what that document is, and what it is not, saves a great deal of trouble at condition discharge.

Why only a licensed assessor can certify

BRE trains and licenses assessors for each scheme, and licences are scheme-specific rather than general. An assessor licensed for new construction is not automatically licensed for refurbishment and fit-out, and licences are subject to continuing requirements including quality audits of submitted assessments.

The assessor prepares the evidence, scores the credits and submits to BRE. BRE carries out quality assurance and issues the certificate. So the assessor is not the certifying body, which is why an assessor cannot guarantee an outcome and why a scored assessment can come back with credits questioned.

For a developer, the practical consequence is that the person you appoint has to hold the right licence for the right scheme, and has to be willing to put their name to the evidence. Ask for the licence details at fee proposal stage. It is a reasonable question and any assessor will expect it.

What a pre-assessment can and cannot say

A pre-assessment estimates the credits a scheme is likely to achieve, given the design as it stands and the commitments the client is prepared to make. It is not registered with BRE, it produces no certificate, and it binds nobody.

What it can do is give the local planning authority a reasoned basis for believing the scheme will reach the rating the local plan asks for. A well-made pre-assessment sets out each credit as achieved, targeted or not sought, states the evidence that will be needed for the targeted ones, and identifies who has to do something and when.

What it cannot do is turn an aspiration into a commitment. A pre-assessment that scores every borderline credit as achieved, with no note on how, is a document that will be contradicted at design stage.

Scheme versions and choosing the right one

BREEAM schemes are versioned and are periodically replaced, with transition periods during which either version may be used. The version applicable to a project is fixed at registration, and credits, weightings and minimum standards differ between versions.

That has two consequences. A pre-assessment prepared under one version and a design stage assessment registered under another will not reconcile, and the difference will show up as an apparent drop in score that nobody can explain. And a project that sits unregistered for a long period between planning permission and start on site may find the version it was assessed against has been withdrawn.

So state the scheme and version explicitly in the pre-assessment, and register the project as soon as the design is far enough advanced to make the version choice deliberate rather than accidental.

How the planning condition is usually worded

Most authorities use a two-stage condition. The first requires a design stage assessment and interim certificate demonstrating the stated rating, submitted before development begins or before superstructure works. The second requires the post-construction certificate within a set period of first occupation.

Two points are worth negotiating when the condition is drafted. The trigger for the first stage should be a point at which the design is actually fixed, because a condition requiring an interim certificate before any operation on site forces the design team to complete work they would normally do later. And the rating should be expressed as the rating targeted in the pre-assessment, not as a higher one that appeared in a policy aspiration.

Where the condition names a specific scheme version, ask for wording that allows the successor version to be used, since the version in force at registration may not be the one in force at the date of permission.

Timing the appointment

Credits are lost by sequence more often than by cost. Several categories require action at defined points in the design and construction programme, and they cannot be claimed retrospectively.

1. Appoint the assessor at concept design, before the structural strategy and the site layout are settled.
2. Hold a credit workshop with the design team to allocate responsibility for each targeted credit.
3. Confirm the specialist appointments the scheme depends on, including any ecologist working to the scheme's definition of a suitably qualified professional.
4. Register the project with BRE and confirm the scheme version.
5. Build the evidence requirements into the design team's information release schedule.
6. Track the score at each design stage rather than discovering it at the end.

The credits most often lost are the ones requiring something to have happened before it was thought about: a site survey completed before clearance, a consultation carried out at the right stage, a commissioning strategy agreed before the services design was finished.

Reading a score realistically

When a pre-assessment lands on your desk, work through it in a fixed order.

Check the rating claimed against the minimum standards for that rating, because BREEAM sets mandatory minimum credits at each level and a scheme can hold enough points overall while failing a minimum standard. Check how many credits sit within two or three points of the threshold, since a rating achieved with a margin of one credit is not achieved at all in practice. Check whether innovation credits are counted in the headline figure. Check which credits depend on a client commitment that has not yet been made, such as a travel plan, a post-occupancy evaluation or a commitment to third-party certified materials.

Then ask the awkward question: which three credits are most likely to fall away, and what happens to the rating if they do. An assessor who has already thought about that will answer immediately. One who has to go away and model it has not tested the score.

Where a scheme is close to a rating threshold, the honest position is to say so in the planning submission and to explain the contingency. Officers deal with sustainability evidence constantly and they can tell the difference between a score with headroom and a score built on optimism. Declaring the margin costs nothing at application stage. Discovering it at condition discharge, two years later and with the design frozen, costs a redesign.

A BREEAM Pre-Assessment sits alongside the other sustainability documents rather than replacing them. The Energy Statement carries the energy hierarchy and the Part L position, and the Sustainability Statement covers the wider policy commitments, and the three should agree on the same design assumptions.

Certification requires a licensed assessor, and professional review of any draft is strongly advised before it is submitted. PlanScope's professional directory is one route to a reviewer for a draft document.
