Budgeting a BREEAM assessment across both stages

BREEAM is two assessments, not one, and budgets that treat it as a single line fail at the second. The breeam assessment cost stages are the design stage, which produces an interim certificate on the drawings and specifications, and the post-construction stage, which produces the final certificate on what was actually built. A planning condition usually requires both: the interim certificate before work starts and the final one within a set period after occupation.

Four cost heads sit behind that. Registration and certification charges paid to the scheme operator, the licensed assessor's fees, design team time to earn the credits, and sub-consultant work for credits that need a specialist. The fourth is the one appraisals miss.

Registration and certification charges

The scheme is operated by the Building Research Establishment, which charges to register a project and to certify it at each stage. Those charges scale with floor area and building type, and they are published as fee scales that change, so take the current figures from the scheme's own schedule rather than from a previous project.

Two things to note when you budget them.

Registration happens once, early, and it has to be done before certain credits can be claimed. Certification is charged separately at design stage and at post-construction stage, so the certification line appears twice in the cash flow, often two or three years apart.

Where a project changes substantially between stages, re-registration or a revised assessment can be needed, which is a cost nobody allows for.

Assessor fees at each stage

Only a licensed assessor can carry out the assessment, and the fee is quoted for the scheme rather than from a rate card. It depends on floor area, the number of building types, the complexity of the credits targeted and how organised the design team is.

Expect the fee to be structured in two parts matching the two stages, with the design stage normally the larger because that is where the evidence framework is built. Ask specifically what the quote includes.

• Pre-assessment and the credit strategy workshop.
• Design stage evidence collation, submission and the quality assurance queries that come back.
• Site visits during construction and the record keeping that supports them.
• Post-construction submission, including as-built evidence and commissioning records.
• Responding to a second round of queries, which is common.
• Any re-submission if a credit fails.

Appoint the assessor before the design is fixed. Several credits reward actions taken at a particular stage, such as the project brief and design process credits and the low and zero carbon feasibility study, and they cannot be earned retrospectively. An assessor brought in at technical design will tell you which credits you have already lost.

Design team time the credits demand

This is the largest cost and it rarely appears as a BREEAM line at all, because it is hidden inside the architect's and engineers' fees.

Two practical consequences. If the design team's appointments were priced without reference to a target rating, the additional work will come back as a variation. And where the target rating is set by a planning condition rather than by the client, that variation is unavoidable.

Write the target rating into the design team appointments at the outset, and name the credits each discipline is responsible for. A credit with no owner is a credit that is lost.

Evidence collection on site

The post-construction stage is an evidence exercise rather than a design one, and it fails for documentary reasons more often than technical ones.

What has to be captured during construction includes material certificates and responsible sourcing documentation, waste transfer records with the recovery figures, commissioning records for services, site monitoring data for energy and water use during the build, and photographic records of elements that will be covered up.

That is a contractor task, so it belongs in the preliminaries and the employer's requirements, with a named person responsible. A contractor appointed on a contract that says nothing about BREEAM will treat the evidence as somebody else's problem, and the cost of reconstructing it afterwards is substantial.

Allow for the assessor's site visits too, since attendance at key stages is part of how the as-built position is verified.

Specialist sub-consultant credits

Some credits need a discipline the core team does not have, and each one is a separate fee.

An ecologist for the land use and ecology credits, who must meet the scheme's definition of a suitably qualified professional. An acoustician for the internal and external noise credits, with design stage calculations and post-construction testing. A security specialist for the security needs assessment, often involving the police designing out crime officer. A life cycle assessment specialist where the materials credits are being pushed. And an accessibility consultant where inclusive design credits are targeted.

The post-construction acoustic testing is the one most often forgotten. It is a site test with a cost and a programme implication, and it can only be done once the building is substantially complete, which is exactly when the programme has no slack.

These overlap with documents you need for planning anyway. A BREEAM Pre-Assessment submitted with the application establishes the target and the credit strategy, and the modelling behind an Energy Statement feeds the energy credits directly. Where the authority also wants a Sustainability Statement, the three should share one set of figures.

The cost of a rating lost at completion

If the condition requires Excellent and the final certificate says Very Good, you are in breach of a planning condition.

The practical consequences run in this order. The authority may require an explanation and remedial measures. It may serve a breach of condition notice, against which there is no appeal. An application under section 73 to vary the condition is possible but is a fresh application with publicity, and an authority that imposed the rating as policy will resist varying it. And where funding is tied to certification, the lender or purchaser may hold retentions or refuse to complete.

The gap between stages is usually caused by three things: value engineering that removed a specified product, missing evidence for a credit that was designed in, and a commissioning or testing result that fell short.

So carry a credit buffer. Targeting two or three credits above the threshold costs design effort at the start and removes the risk of a shortfall at the end, which is the trade most experienced clients make.

Where targeting a higher rating pays

Going above the required rating is worth considering in three situations.

Where the planning condition or local policy sets a floor and the marginal credits come easily for this building type, for example where a well-insulated form already earns most of the energy credits.

Where funding, lettings or an institutional purchaser requires a particular rating, in which case the certification is a sales document rather than a compliance one.

And where the alternative is a buffer-free strategy on a long programme, since the cost of the extra credits is usually less than the cost of a failed condition.

Where it does not pay is at the top of the scale. The highest rating carries mandatory minimum standards across several credit areas that drive specification decisions well beyond the assessment itself, and that should be a client decision taken with the cost consultant rather than a sustainability aspiration.

The honest uncertainty is fee prediction. Assessor and sub-consultant fees vary widely with building type, and the published scheme charges are revised, so treat any figure in an old appraisal as indicative only and get three quotes.

PlanScope pricing gives a fixed figure per report, which helps when you are separating the drafting cost of the planning stage documents from the assessment fees that follow. Comparing it against the scope in what a planning agent's fixed fee usually includes is a useful cross-check on where the boundaries sit.
