The Escalation Ladder — Where Is Your Letter?
- Payment demand / reminder — the debt exists and is unpaid. Easiest stage to fix.
- Warning letters — increasingly firm, may mention enforcement or debt collection agencies acting for HMRC.
- Notice of Enforcement — the formal legal warning that enforcement agents may visit after the notice period. Still fixable by arrangement — but the clock is now real.
Whatever the stage: don't ignore it, and don't wait for the next letter. Every step up adds cost and stress that a phone call would have avoided.
