Normal (ish) process if you want a like for like replacement car. Other options would be to 1-pay for a car yourself and reclaim from the third party 2- use the policy and get a small courtesy car (not checked the DLM policy but this is a usual benefit and subject to availability).
Option 1 and 2 would normally be subject to payment of policy excess and temporary reduction of NCD.
From experience credit hire would be the route to use if wanting the claim to be settled non-fault. The reason is that costs are far higher and a greater effort is made to fight liability.
