Yes, they will not insure an unlimited liability.
Hmmm - it really is a commercial decision for you.
Clearly if you accept an unlimited liability and there is a claim, your insurers will only allow those costs to their insured limit, you would have to pay for the difference.
There is simply no way to mitigate this.
This is an unreasonable term to insist on and you should refuse.
I can't see how many insurance company would allow this unlimited basis and therefore the client should not accept that either
But sadly there is no legal way to mitigate this, but it will be a commercial decision for you.
Investigate what losses they think they could suffer and see if that is within your insurance limits
Can I clarify anything for you about this today please?
Hmm, I assume an unlimited liability clause would actually be enforceable?
If this is a business agreement then yes
You dont have the same rights as a consumer
OK, I see.
Can I clarify anything about this for you today please?
No that is fine.
