011 SAP, EPCs & Building Regulations Explained
Most property projects don’t fail on bricks and mortar — they fail on compliance, energy performance, and details developers underestimate.
In this episode, we sit down with Productive Energy founder Nate to demystify SAP, EPCs, ventilation, airtightness, and sound testing — and show you how to get them right first time.
What we cover:
What SAP assessments really are — and why they matter more than most developers think
The biggest EPC killers in refurbishments, HMOs, and conversions
SAP Design vs SAP As-Built (and why missing documents can cost you money)
Easy, low-cost upgrades that have the biggest EPC impact
Ventilation mistakes that lead to mould, complaints, and failed inspections
Airtightness tests explained simply (and how not to overdo it)
Why sound tests fail — and proven acoustic build-ups that pass
What’s unique (and risky) about commercial-to-residential compliance
How poor early design decisions massively increase costs later
How to avoid retests, delays, and Building Control nightmares
The paperwork every developer must collect during a project
The biggest EPC myths developers still believe
