What is a Mental Capacity Assessment?
Imagine you have a friend who sometimes struggles to choose the right clothes for the weather. On a cold day, they might wear a T-shirt, and on a hot day, they might wear a thick jacket. You might wonder, "Do they understand how to choose clothes based on the weather?" In the same way, sometimes its necessary to check if someone understands certain important decisions about their life, like managing money or deciding on medical treatments. This check is called an "assessment of mental capacity." Your mental capacity reflects your ability to understand information and make informed decisions. This encompasses decisions across any aspect of your life. The Mental Capacity Act (2005), the key legislation governing mental capacity in the UK, clearly states that capacity is 'decision specific.' This indicates that while you might possess the capacity to make certain decisions, you could lack the capacity for others. As specialist mental capacity assessors, our approach is therapeutic in nature, focusing on assessing your mental capacity for specific decisions that you might find challenging, or in situations where concerns have been raised about a potential lack of capacity. Our mental capacity assessments are tailored to address these individual needs, ensuring a comprehensive understanding of your capabilities in making particular decisions.
Two Services, One Gold Standard

Mental Capacity Assessment
Ideal for routine legal or financial choices, writing a Will, granting a Lasting Power of Attorney, or deciding on health and welfare matters. Delivered by experienced professionals, every assessment is decision-specific, person-centred and fully compliant with the Mental Capacity Act (2005). Whether you’re planning ahead or responding to a solicitor’s request, our streamlined service supplies the clear, courtroom-ready documentation you need, efficiently and with genuine care.

Advanced Mental Capacity Assessment
When the stakes are high, large estates, family disputes, suspected undue influence or rapid cognitive change, our AMCA brings science, structure and courtroom-ready clarity. Following a brief telephone consultation, we blend the MCA 2005 two-stage interview with a bespoke psychometric battery, translating concerns such as grief, anxiety and vulnerability into hard data. You receive a CPR35-compliant report with an easy-to-read Psychometric Summary, offering deeper insight into emotional, cognitive and situational risk factors. Two visits, one robust safeguard.
