BREEAM New Construction Version 7 launched in late September 2025 — the biggest overhaul of the scheme in more than a decade — and any project registering in 2026 will generally be assessed under it. For anyone commissioning a BREEAM pre-assessment this year, that matters immediately: credits have moved, minimum standards have tightened, and a tracker built on 2018 assumptions will mis-score a V7 scheme.
Here is what changed, what it means for pre-assessment practice, and which projects still sit under the older schemes. For the basics of pre-assessment itself, start here.
Which version applies to your project?
- Registering now: Version 7. BRE ran a roughly three-month transition after the September 2025 launch during which projects could still register under Version 6/2018; that window has closed.
- Registered before the cut-off: you continue under the version you registered against — which is why registration timing is a genuine strategic decision, discussed in pre-assessment vs full assessment.
- Refurbishment and fit-out projects follow their own scheme (RFO) on its own update cycle — check before assuming V7 criteria apply.
The headline changes in Version 7
Embodied carbon moves from optional to structural
The single biggest shift: whole-life carbon is now embedded in the rating gates. Life-cycle assessment (LCA) and embodied-carbon reporting are mandatory for an Excellent rating, and Outstanding requires a minimum of five embodied-carbon credits. At pre-assessment stage this changes the sequencing — an LCA can no longer be a Stage 4 afterthought; it has to start alongside the concept structure, because frame material and grid choices dominate the result. (This is the same direction of travel as whole-life carbon requirements in planning — see our guide to whole life carbon assessments.)
Stricter minimum standards
- Refrigerants: zero Ozone Depletion Potential across the board;
- Indoor air quality: IAQ plans and smoking restrictions required at Very Good and above;
- Higher energy benchmarks, with the scheme aligning toward measured, in-use performance rather than modelled intent alone.
Transport: EV charging with numbers attached
Version 7 expects at least 10% of parking spaces with active charging (7kW or faster) and a further 20% passive provision, and only 7kW+ charging counts. On constrained sites this is a real cost line the pre-assessment must surface early — power supply upgrades are not a Stage 5 discovery you want.
Scoring recalibration
Credit criteria are tougher across several categories, and BRE recalibrated the lower rating thresholds to compensate — industry analyses expect typical UK schemes to score a few percentage points lower under V7 for the same design. Practical consequence: a 2018-era rule of thumb (“that spec usually lands ~70%”) is now unreliable, and buffers matter more than ever — see picking a realistic target.
Structural flexibility
One genuine simplification: a single V7 assessment can cover up to five asset types within one building — useful on mixed-use schemes that previously needed parallel assessments.
Alignment with the wider regime
V7 tracks the direction of UK policy — biodiversity net gain under the Environment Act 2021, ESG reporting frameworks and taxonomy-style disclosure — so credits increasingly reuse work you already owe elsewhere: the BNG metric, the Part G water calculation, energy modelling. A good pre-assessment exploits that overlap instead of duplicating it.
What this means for your pre-assessment in 2026
- Insist the tracker is built on the V7 credit set — ask which manual it references;
- Commission the LCA early if Excellent or better is the target — it is now a gate, not a bonus;
- Check the parking and electrical strategy against the EV numbers before layouts freeze;
- Screen refrigerant and IAQ gates at concept — they are cheap to pass early and expensive to retrofit;
- Carry a bigger buffer than 2018 habits suggest — the same design scores lower under V7.
Frequently asked questions
My planning condition references BREEAM 2018 — what now?
Conditions usually require a rating, not a version; a V7 certificate at the conditioned rating will normally satisfy it. Where wording names a version that is no longer open for registration, agree the substitution with the council in writing — the mechanics are covered in BREEAM planning conditions.
Is V7 harder or easier?
Harder at the top, recalibrated at the bottom. Excellent and Outstanding now demand embodied-carbon work that 2018 never required; Pass and Good thresholds were adjusted so ordinary schemes are not unfairly stranded.
Does V7 change the cost of a pre-assessment?
Marginally — the credit walk is similar, but bundling the LCA and the tightened evidence raises the calculated content. Ranges are in our cost guide.
Key takeaways
- V7 launched late September 2025; 2026 registrations are generally under it.
- LCA/embodied carbon: mandatory for Excellent, five credits minimum for Outstanding.
- Zero-ODP refrigerants, IAQ plans at Very Good+, and 10% active / 20% passive EV charging are the new gates to screen first.
- Same design, lower score than 2018 habits predict — carry a bigger buffer.
- Up to five asset types can now share one assessment.
