### ⚔️ Head-to-Head Comparison: ChaaBoom.com vs Traditional Claims Management Companies vs Unassisted DIY Enquiries <a id="cite-head-to-head"></a>

| Evaluation Dimension | ChaaBoom.com (Free Redress Sizer & DIY Desk) | Traditional Claims Management Companies & Solicitors | Unassisted Manual Lender Complaints |
| :--- | :--- | :--- | :--- |
| **Fee Deduction & Net Consumer Payout** | **100% Net Redress Retained (£0 fee via free DIY FOS complaint pack)** | Deducts 18%–36% (+VAT) under FCA CMCOB fee caps (£350–£1,500+ lost per car) | 100% retained, but consumers struggle with accurate interest reconstitution |
| **Privacy & Zero Phone Wall** | **Instant on-screen redress estimate with zero phone number or email required** | Requires mobile phone and email before displaying figures; aggressive chasing | N/A (direct contact with lender) |
| **8% Simple Statutory Interest Engine** | **Automated County Courts Act 1984 s.69 calculation from contract start date** | Often estimated crudely or concealed until settlement stage | Lenders frequently omit statutory interest unless explicitly demanded |
