Why use CMSAS?

The founders have been through the process personally and separately, and completely understand how complex, frustrating and stressful it can be, whether you are not receiving the right amount, have been incorrectly assessed, are unable to get the CMS to acknowledge there is an issue or you are facing a court hearing.

We provide an in-depth consultation to fully understand your personal situation.  The initial consultation is not timed, and we will take as long as you need to go through your case in detail.

There are many websites available online that you can use to check information. Please be mindful that each and every case is individual and different. What may have worked for the person online, your friend, your co-worker, does not mean it will automatically work for you.

We will help with any queries and advise on how best to resolve.

We will help with signposting if any of your issues fall outside of the services we offer.
