Mills & Reeve system for employees.
Seamless, cradle to grave claims handling combining SiS’ specialist claims management expertise with Mills & Reeve’s legal insight, delivering smarter, scalable solutions for insurers.
SiS Claims, now part of Mills & Reeve, offers a complete claims handling solution from first notification to resolution. Our integrated approach combines technical claims expertise with legal insight, helping clients manage risk, control costs and protect and enhance relationships.
With tailored services, centralised coordination and bespoke MI reporting, we deliver consistency and commercial value. Whether supporting underwriting strategy or resolving complex disputes, our team works collaboratively to achieve better outcomes. Our proprietary claims management platform, Minerva, gives clients 24/7 access to real-time data, documents and MI. It is flexible, fully compliant with Lloyd’s V5, Solvency II, and supports robust performance monitoring.
Each client receives tailored MI packs, typically on a monthly basis, covering claim progression, reserving, trends, and service-level performance. Regular review meetings are held to ensure alignment with underwriting goals and operational targets.
We also capture underwriting information to provide analysis on the performance from individual risks to entire portfolios.
Minerva ensures transparency and performance monitoring, giving clients real-time access to data and all relevant documents to a claim.

We have received an average audit score of 98% on all audits undertaken by our clients on us last year.
Below is a collection of our bite-sized legal webinars delivered regularly by our legal experts to help you keep up to date with our insights on topical subjects in the sector.
In short, straight away! We have a core team of claims managers that can be supported by a large team of lawyers as and when the need arises. Therefore if an insurer wished to transfer a large portfolio of claims to us we can ‘hit the ground running’ and have claims reviewed and uploaded onto Minerva in a short space of time.
Yes. Whilst SiS is now part of a large law firm, we have kept our service flexible and adaptable to an insurer’s requirements. Our preferred MO is to meet with an insurer prior to instruction, so we can identify requirements and respond accordingly. We can of course offer our own suggestions to what claims service the business will require given our extensive experience!
Yes. As part of our service an insurer (and MGA) will be provided access to Minerva which will enable you to view all relevant financial and claim related data. You will also be able to view all correspondence pertaining to a claim on a ‘real time’ basis.
Yes. We appreciate that an insurer might want to operate a panel of solicitors. We have experience of working with most major insurance law firms because for many years we acted as an independent claims TPA prior to our acquisition by Mills & Reeve in April 2025. We have deliberately maintained the SiS brand so a panel can be operated smoothly and without confusion.
We deliberately make the decision to instruct a panel solicitor a point of referral to an insurer client. This way an insurer can be assured that a solicitor appointment is only made on those claims that genuinely need one.
Yes. We are incorporated in Ireland and have trading name of SiS Claims (Europe). In addition, we currently manage claims for insurers in Hong Kong, Singapore, Australia and Kenya.
