How It Works
Two services, sometimes the same car
A body shop compiles an Audatex estimate and sends it for approval. From that estimate we can also compile an engineer’s report — but each has a different customer. Here’s how we sit between both sides.
Body Shop
Estimate compiled
SJM · Estimate
We negotiate & authorise
We review and negotiate the costs with the insurer, authorising the job at the best fair rate for the garage.
SJM · Report
Engineer report compiled
From that same estimate we can compile an independent engineer’s report built to withstand scrutiny
Claims Pro
Report delivered
The report goes to the accident management company, broker or insurer who can rely on its findings.
FAQs
Frequently asked questions
Questions we’re asked most often by body shops and claims professionals across the UK. Can’t find what you need? Get in touch.
What Service Do You Provide ?
We provide two core services: an estimating service — Audatex estimates plus dealing with the insurance companies to get jobs authorised — for body shops, and independent engineer reports for accident management companies, insurance brokers and insurers.
Are you only working for body shops?
No. We sit impartially between both sides. We negotiate the best fair rate on a body shop’s estimate, and we provide firm, fair engineer reports that insurers and claims professionals can rely on. Independence is the whole point.
Do you work across the whole UK?
Yes. We support body shops and claims professionals across the entire UK, with a strong focus on Scotland. Every assessment is carried out digitally, so location is never a barrier.
How does the digital assessment process work?
What if a body shop doesn’t have Audatex?
Are your assessors accredited?
Yes. Our assessors hold CAE, AMIMI, ATA, VDA and AQP accreditations and bring years of hands-on experience to every assessment.

What people say about us
Quick, accurate estimates and they handle the insurer back-and-forth for us. Feels like having an in-house assessor without the overhead.
Body Shop Manager
The engineer reports are thorough and stand up to scrutiny. Exactly the kind of independent assessment we need to settle claims with confidence.
Claims Manager
Fast turnaround and genuinely fair. They negotiate hard for the garage but the reports we receive are firm and balanced.
