Where they differed most
A decorator's contract contains: 'The Client shall indemnify and hold harmless the Contractor against all claims, losses, damages and expenses howsoever arising in connection with the Works, save to the extent caused by the Contractor's negligence.' In max 80 words of plain English: what this clause makes the customer promise, the one carve-out it contains, and the question to ask before signing.
You promise to pay for any claims, losses, or damages related to the decorator's work. The one carve-out is that the decorator remains responsible for anything caused by their own negligence. Before signing, ask: "Does my home insurance cover this broad financial promise?"
The customer promises to reimburse and protect the contractor from any claims, losses, damage or expenses connected with the work, however they arise. The only exception is where the contractor’s own negligence caused them. Before signing, ask: **What specific risks could this make me responsible for, and does my insurance cover them?**
