Self-build homes, garden annexes and big extensions can be exempt from the Community Infrastructure Levy, which is often a five-figure bill. But only if the right forms reach the council in the right order before a spade hits the ground. CIL Guard checks if you qualify, builds your deadline timeline, reminds you, and keeps your evidence safe for the 3-year clawback period.
