Will your new build pass its Part O Overheating Assessment?
A failed overheating assessment found late is always the expensive kind.
At design stage, most issues can be fixed with a quick specification tweak.
Mid-build or at completion, your fabric may already be locked in. That means fewer options, bigger bills, and potential delays to completion certificates or plot sales.
That’s why UK Building Compliance has launched the 60-Second Overheating Pass Check.
A free online tool that gives you an instant traffic-light risk rating and helps you understand whether your project may qualify for the Simplified Method or need a full TM59 assessment.
✅ 5 quick questions
✅ No technical jargon
✅ Takes less than a minute
✅ Instant pass-risk verdict
✅ No sign-up required for the headline result
✅ Option to unlock a full report showing what to fix first
Built by our experienced Part O assessors, it gives you a fast indicator of your project’s compliance health before small issues become expensive fixes.
Don’t risk your completion certificates.
