On receipt of a referral our experienced team will offer a choice of experts, along with cost estimates and timescales. We ensure that those experts have a skill set tailored to your needs and are local to you. We can do this on the same day, usually within the hour. Most assessments are completed within 6 weeks of instruction, although shorter timescales can often be secured.


All assessments can be completed remotely or in person either on a fixed fee basis or, for assessments within legal proceedings, at legal aid rates.

adult mental capacity assessments

Our nationwide network of experienced Mental Capacity and Deprivation of Liberty Safeguarding [DoLS] assessors are appropriately trained and qualified, all either approved under section 12 of the Mental Health Act 1983 or registered medical practitioners with at least three years’ post-registration experience. Additionally, our Best Interest Assessors [BIA] all have at least two years’ post-qualification experience and have completed approved training to be a BIA.

Our assessors are supported by a team of highly trained, dedicated case handlers who will be responsible for your case from start to finish. This means you will have one point of contact throughout the assessment and reassurance that if any issues arise, they will be dealt with quickly and effectively.
Our adult based assessments include:

  • Deprivation of Liberty Safeguard Assessments (including BIA)
  • Care Act Assessments (including Carers Assessments)
  • Mental Capacity Assessments (including CoP3 for Court of Protection)
  • Safeguarding Adult Reviews (SAR)

We aim for all of our assessments to be completed within a twenty-one-day timescale, meeting the legal requirements for a standard authorisation. However, we may also be able to complete an assessment in as little as 7 days in cases where the applicant is already receiving care and where an urgent authorisation has been requested.

The cost agreements that we provide are all based on a fixed fee framework and are dependent on which sections of the DoLS assessment you have requested.
