Does my EPD become invalid the moment its PCR is updated?

No. Your existing EPD remains valid until its normal expiry date, yet any renewal must follow the new PCR version and its updated rules.

Can I extend an EPD without running a new LCA?

Some operators offer a 6–12 month extension if impact changes stay below set thresholds (often 10 %). You still need to submit evidence and secure verifier sign-off.

When should I issue a brand-new EPD instead of an addendum?

Introduce a new plant, alter core chemistry, or see impact shifts above operator limits, and you’ll need a completely re-verified EPD.

What happens if my EPD expires while a renewal is in progress?

Program operators usually delist the EPD until the new version passes review, so sales teams could lose specs in that gap.

Does my EPD become invalid the moment its PCR is revised?

No. The current EPD stays valid until its own five-year expiry. Only the next update must follow the new PCR.

How long does a renewal review usually take?

Well-prepared files often clear verification in four to six weeks, while poorly organized data can stretch the process past three months (Fraunhofer, 2024).

Keep Your EPD Alive: Validity & Updates

Why “five years” isn’t always five years

EN 15804-based PCRs typically set a five-year validity window; programme operators then layer on their own conditions. Skim the fine print before you lock your launch date.

The clock starts with the publication date

Your EPD’s validity runs from the publication date, not the reference-year data window. If your declaration goes live in February 2024, a five-year window would typically close in February 2029—operator rules vary. Misreading this start line can still cost months of shelf life.

PCR revisions: friend, foe, or both?

Most construction materials lean on generic PCRs that are reviewed about every five years, though schedules vary by operator (UL Solutions, 2025). Publishing a new PCR doesn’t cancel existing declarations; they stay valid until their stated expiry. The next renewal must follow the then-current PCR—operators publish transition windows, such as the phase-out of PCR 2019:14 v1.3.4 on 20 June 2025 (Environdec, 2025).

Minor tweaks vs full re-issue

Program operators split changes into three buckets:

Editorial adjustments—typos, branding tweaks—often require no new verification.
Minor technical updates that leave impacts largely unchanged may be handled through an addendum and keep the original expiry.
Substantive changes—new plants, major process or material shifts—can demand re-verification or an entirely new EPD. Requirements differ by scheme (BRE, 2024; SCS Global Services, 2025).

Data drift: when to update early

Energy markets, supply chains, and scoped carbon targets rarely sit still for half a decade. Several programmes treat a cradle-to-gate impact movement of roughly 10 % as a trigger for an early update (EPD Australasia, 2024). Refreshing sooner keeps scores competitive and stops a rival from waving a greener sheet at the bid table.

Who signs off on extensions?

Extension rules are programme-specific. Some allow a short grace period when changes stay within minor-amendment thresholds, while others require full re-verification at expiry. Either way, assemble QA memos, utility invoices, and a concise variance analysis before you ask. Missing docs invite delays.

Smart renewal checklist

Mark the PCR and publication-date expiry in one shared calendar.
Pull production data annually to spot shifts earlier than auditors do.
Track competitor PCR adoption so your spec stays apples-to-apples.
Block six weeks for verification; summer holidays still happen.
Update sales collateral the same week the refreshed EPD posts. Don’t let the field team roam with stale PDFs.

Keep the stopwatch in sight

Treat an EPD like a software license: valuable, but only if current. Build renewal milestones into product roadmaps, watch PCR bulletins, and keep data flowing so the next update feels routine, not a fire drill. Nobody wants that last-minute panic.
