What a BREEAM pre-assessment costs and what it commits you to

A planning condition requiring BREEAM Excellent is a commitment to spend money for the next three years, not a line in a planning statement. The breeam pre assessment cost itself is modest: a licensed assessor reviews the design, completes the pre-assessment estimator and reports a predicted rating. What follows, design stage certification, evidence gathering through construction and a post-construction review, is where the budget actually goes.

So the decision worth getting right at application stage is which rating you offer, because the condition will hold you to it.

What a pre-assessment is for at planning stage

Many adopted local plans require non-residential development above a floorspace threshold to achieve a stated BREEAM rating, and ask for a pre-assessment with the application to show the rating is achievable. The pre-assessment is a prediction, prepared by a licensed assessor using the scheme's own estimator tool, listing the credits targeted and the resulting score.

It is not a certificate. Nothing is registered with the Building Research Establishment at this point and no rating has been awarded. What the council gets is a credible statement that the design can reach the rating, with the credits identified.

The ratings run Pass, Good, Very Good, Excellent and Outstanding. Scheme versions are updated periodically, so confirm with the assessor which version applies to your project and say so in the submission, because the credit structure differs between versions.

Councils expect a suitably qualified author for this work, and a BREEAM Pre-Assessment prepared by someone who is not a licensed assessor is likely to be challenged. Professional review is strongly advised.

Assessor fees against certification fees

Two separate costs, often conflated in a budget.

The assessor's fee is professional time: reviewing the design, running the estimator, advising the design team, assembling evidence, submitting to quality assurance and responding to queries. It scales with the complexity of the building and the number of credits being chased, not with the floor area alone.

The certification fee is paid to the Building Research Establishment for registration and for the issue of certificates, and it is set by published schedules that vary with the scheme and the project. Those schedules change, so take the current figures rather than a number from a previous job.

Credits that require design team input to evidence

The score is assembled from ten categories: management, health and wellbeing, energy, transport, water, materials, waste, land use and ecology, pollution, and innovation. Each credit needs evidence, and the evidence usually comes from someone other than the assessor.

That is the part developers underestimate. An energy credit needs a model from the energy consultant. An ecology credit needs input from a suitably qualified ecologist. An acoustics credit needs measurement and a report. Health and wellbeing credits need daylight modelling. Materials credits need responsible sourcing certification tracked through procurement. Waste credits need site records kept week by week by the contractor.

Each of those is a fee or an hours allowance in someone's appointment, and if the appointments were written before the BREEAM target was fixed, they are variations. Fix the target before the consultant appointments are signed and the credits cost a fraction of what they cost retrospectively.

Three practical savings are available. Appoint a BREEAM accredited professional early to steer credit selection rather than chasing credits at the end. Select credits that the building needs anyway, such as energy and daylight, in preference to bolt-ons. And decide which innovation credits you are not pursuing, explicitly, so nobody prices them.

Post-construction review costs

The post-construction stage is where projects lose credits they thought they had. The assessor has to evidence what was actually built and procured, and if the contractor did not keep the records, the credit goes.

Common losses: responsible sourcing evidence missing for a substituted product, commissioning records incomplete, air tightness or acoustic testing not done at the right stage, waste records not maintained, and a specification change made under value engineering that removed the basis of a credit.

Each lost credit has to be replaced from somewhere else or the rating drops. Replacing credits late is the most expensive way to buy them, and on a conditioned rating there may be no alternative. Budget a contingency for exactly this, in the same way that construction management plan conditions carry their own cost once the site is running.

Where a conditioned rating locks in cost

Read the condition wording carefully, because the variants behave differently.

A condition requiring a pre-assessment to be submitted and approved is light. A condition requiring the development to achieve a stated rating, evidenced by a design stage certificate before commencement and a post-construction certificate before occupation, is a hard commitment with two gates in the programme.

The occupation gate is the one that bites. A final certificate that has not issued can hold up occupation of a completed building, which is a cost measured in rent rather than in fees. Where that risk is real, negotiate the condition at application stage to allow occupation on submission of the post-construction evidence, with the certificate to follow.

And resist offering a rating above the policy requirement to improve the planning case. An offered rating becomes a conditioned rating, and the extra credits are paid for by the project rather than by the goodwill they bought.

Interaction with energy and carbon work

The energy category draws on the same modelling that supports the Energy Statement, so commission them together and make sure the assumptions match. A pre-assessment claiming an energy credit that the energy statement's model does not support is an inconsistency an officer will find.

Materials and waste credits overlap with life cycle work, and where a Whole Life Carbon Assessment is required, the data gathering serves both. The RICS whole life carbon methodology and the BREEAM materials credits ask related questions about embodied impact, and running them as one exercise is substantially less work than running them twice.

In London the picture is denser again, with energy, whole life carbon and circular economy reporting all requested, and the sequencing of those documents affects the fee more than their individual scope does.

Budgeting from pre-assessment to certificate

Build the budget in five lines rather than one: pre-assessment, registration and design stage certification, specialist inputs needed to evidence the selected credits, contractor record keeping allowance, and post-construction assessment with a credit contingency.

Then ask three questions before submitting the application. What rating does the policy actually require, as opposed to what the officer has suggested. Which credits are we relying on, and whose fee covers the evidence for each. And what does the condition wording allow us to do if a credit is lost in construction.

Answering those three at application stage is the difference between a conditioned rating that costs what you expected and one that does not. A draft can set out the structure, the policy references and the credit schedule headings, with the credit scoring left to the licensed assessor, and the professional directory is the route to that sign-off.
