How to Review Motor Insurance Repair Estimates

A useful review explains whether the work is supported, how the costs were calculated and what still needs clarification. This guide provides a practical approach for insurers, assessors and assessment companies.

Before checking prices, confirm that the quotation and assessment relate to the same vehicle and claim. Check the reference, vehicle details, inspection date and estimate version. A comparison is unreliable when one reviewer uses the original quotation and another uses an updated submission.

Identify the repairer’s quotation, the assessor’s proposed estimate and any amounts recorded after review. These documents serve different purposes. A proposal should remain identifiable as a proposal until the relevant reviewer has made and recorded a decision.

Two estimates with different totals may describe different work. One may include a replacement part where another proposes repair. One may include additional paint preparation or an operation needed to remove and refit a component.

Read the line items before judging the total. Identify the part or operation, the proposed action and the evidence behind it. Where repair or replacement depends on technical judgement, ask for the reason and any inspection limits to be recorded.

The lowest estimate is not automatically the most appropriate estimate. The review should establish whether the proposed work is supported and whether the costs have been explained.

For each item, check the quantity, unit price and line total. For labour, check the hours or other stated basis and the rate used. Review paint and materials charges in the form supplied, rather than assuming that every repairer uses the same calculation method.

Check for repeated operations or charges that appear in more than one line. A repeated description may be valid, but it should be understandable. Confirm how discounts, taxes and other adjustments have been applied where relevant to the quotation.

Arithmetic checks cannot establish whether work is necessary. Combine them with the inspection findings, supporting documents and the relevant reviewer’s judgement.

A note saying “estimate reduced” does not tell the next person what changed. Record the original item, the proposed change and the reason for that change. Reference the photograph, inspection finding, quotation or other support where available.

For example, consider a fictional estimate that proposes replacing a bumper while the assessor recommends a repair. The useful review question is whether the inspection supports that repair, what work it includes and how the revised cost was calculated. Simply replacing the total with a smaller number leaves those questions unanswered.

If the evidence is insufficient, request clarification. Distinguish an unsupported item from an item that has been reviewed and declined, so the record accurately reflects the decision.

Make questions precise enough for the assessor or repairer to answer. Instead of “please revise labour,” identify the operation and ask how the quoted time was determined. Instead of “provide evidence,” name the component and the condition the reviewer needs to understand.

Keep requests and responses connected to the estimate version under review. If a response introduces new work or a changed price, identify the revision and show what changed. This helps reviewers avoid repeating questions already answered on an earlier version.

Separate acceptance of the assessment report from approval of individual costs and from the final claim decision. Those steps may belong to different roles and may follow different internal procedures.

Record which items were accepted, adjusted or left pending, together with the reason and the relevant evidence. Make outstanding questions visible. Avoid presenting a partially reviewed estimate as fully approved.

When a revised package is submitted, retain an understandable history. The team should be able to see the current version and trace significant changes without searching across unrelated emails.

Before completing the review, ask:

• Does the estimate belong to the correct claim and vehicle?

• Are the current quotation and assessment versions clearly identified?

• Is the proposed work connected to relevant findings or evidence?

• Have quantities, rates and calculations been checked?

• Are significant differences explained at item level?

• Are pending questions and review decisions recorded clearly?

The applicable policy, insurer’s instructions and your organization’s procedures determine the requirements for a particular claim. This checklist supports a clear review record; it does not determine coverage or settlement.

A clear estimate review connects proposed work, costs, evidence and decisions. When those pieces are separated, even a straightforward question can require another round of messages.
