The result
A high‑volume housing phase required EPCs delivered at pace, without losing accuracy or creating later compliance problems.
ATSPACE implemented a fast‑track EPC workflow built around structured plot tracking, efficient evidence capture, and early identification of variations. EPCs were issued in rhythm with completions, preventing sales delays and removing EPCs as a last‑minute bottleneck.
Project snapshot

Client: National housebuilder regional delivery team
Site address: Greenwood Fields, Phase 5, 1–78 Cedar Way, Huntingdon PE29 1RF
Building type: Mixed houses and apartments
Plots covered: 78
Programme stage: High‑volume completions over a condensed period
Compliance driver: EPC issue aligned to completion and sales progression
ATSPACE delivery: Plot tracker, evidence checklist, SAP/EPC updates, certificate lodgements, handover‑pack coordination
Engineers: ATSPACE energy assessor team + compliance coordinator
Why fast‑track EPC delivery was needed
The risk wasn’t technical — it was commercial.
When completions are high volume, the issue isn’t one missing EPC. It’s the accumulation of small delays that slow down sales progression.
Typical risks on large phases include:
- multiple plot variations not captured early
- repeated evidence requests
- airtightness results arriving late
- last‑minute changes to heating controls or lighting
- plots signed off as “ready” but lacking EPC‑critical information
ATSPACE’s job was to remove friction and keep EPC delivery aligned with completions.
What ATSPACE did
Step 1: A simple EPC workflow the site could actually run
We implemented a clear workflow with responsibility points:
- plot evidence pack complete
- as‑built variations confirmed
- airtightness result logged
- final review + EPC issue
- certificate filed to correct plot pack
This made EPC progress visible and eliminated chasing.
Step 2: A repeatable evidence checklist by house type
Instead of gathering evidence differently for every plot, we created one repeatable checklist per house type.
This ensured consistency and massively reduced admin.
Step 3: Early capture of the variations that cause delays
We prioritised the variations that typically force recalculation:
- heating controls and thermostats
- lighting specification changes
- ventilation‑fan model and performance changes
- glazing changes
- insulation substitutions
Capturing these early prevented late‑stage correction cycles.
Step 4: Certificates issued in line with completion sequence
EPCs were issued to match the completion forecast so that EPC availability never lagged behind handover readiness.
The main problems we prevented
Problem 1: Missing evidence causing last‑minute scrambling
With the plot tracker and evidence checklist, issues were flagged early — not on completion day.
Problem 2: Multiple crews creating inconsistent inputs
The workflow kept assumptions consistent and logged variations rather than letting them slip.
Problem 3: Airtightness results holding up EPC issue
We prepared plots up to the final input, so once the airtightness result arrived, EPCs could be issued immediately.
Outcome
The phase achieved smooth EPC delivery without becoming a completion bottleneck.
Project outcomes
- EPCs issued in step with completions
- reduced sales‑progression delays
- fewer late evidence chases and rework loops
- cleaner compliance and handover packs
- better control over specification drift
Common mistakes this project avoided
- leaving EPCs until the final week
- managing evidence through scattered emails/photos
- missing small spec changes that shift SAP results
- letting plot variations accumulate without logging
- treating airtightness as the only dependency

Frequently asked questions
What causes EPC delays on large sites?
Missing evidence, late spec changes, and poor plot tracking.
Can fast‑track EPC delivery still be accurate?
Yes — speed comes from process control, not rushed assessments.
How early should the EPC workflow be created?
Before first completions. Early setup prevents repeated delays and reduces admin load.
