Rule library — August 2026 · 31 Checks · Free to read
The rule library
31 ways UK households leak money.
Each Check is one UK recovery rule: who qualifies, what it is typically worth, how long it takes, the evidence you need, the deadline, and the free official route.
All of it is free to read, including the routes we are not selling. The paid Recovery Pack only exists to tell you which of these apply to you and to write the letters.
