Statutory Rules for the 100% Self-Build Exemption (Form 7)
To qualify as a genuine self-builder under Regulation 54A, the development must satisfy strict legal conditions:
1. Sole or Main Residence: The home must be built by or commissioned by an individual for occupation as their principal home.
2. Two-Stage Certification: Form 7 Part 1 (Claiming Exemption) is submitted before commencement. Within 6 months of completion, Form 7 Part 2 must be submitted alongside proof of occupancy (utility bills, council tax bill, electoral roll entry, and building control certificate).
3. Disqualifying Events (Clawback): If the property is sold, let, or transferred within 3 years of the building control completion certificate, it triggers a 'disqualifying event' under Regulation 54C. The full original CIL charge immediately becomes due and payable with statutory late-payment interest.
