Why Mundus exists
Mundus was founded to fill a gap: practical, compassionate support that sits between clinical services and traditional care — help with the everyday things that make life feel manageable again.
Too many people fall through the cracks when they need help with their home environment, routines, confidence or community connection but do not need (or cannot access) clinical or personal care. Mundus offers something different: a calm, person-centred approach that starts from where the person is and works at their pace.
Kayleigh’s vision is for a service that treats people as individuals, not cases — one that builds confidence, independence and community connection through practical, respectful support.
Founder’s Personal Experience
Kayleigh’s own experience of post-natal depression and marriage breakdown gave her a first-hand understanding of how quickly life can change direction. When life enters a period of despair or uncertainty, priorities can change almost overnight. The things that once felt manageable — the home, routines, responsibilities and everyday decisions — can suddenly feel impossible to keep on top of.
There was emotional and psychological support available, but Kayleigh came to recognise that another part of the journey was often left behind. When the door closes and the conversation ends, life is still waiting on the other side. The home still needs managing. Children still need caring for. Routines still need rebuilding. Decisions still need making. And sometimes, the person simply does not have the capacity to know where to begin.
For Kayleigh, that was one of the hardest parts: not necessarily the absence of emotional support, but the gap between receiving support and being able to translate that support into everyday life.
It was through this experience that the idea for Mundus began to take shape.
Mundus was created around the belief that this experience is not unique to one circumstance. It can affect people during marriage or relationship breakdown, parenthood, caring responsibilities, bereavement, periods of poor wellbeing, major life transitions or times when circumstances simply become too much to manage alone.
Mundus looks towards the person’s outward world — their home, routines, organisation and everyday environment — and asks: what practical support could help make life feel manageable again?
The aim is not to take away a person's independence or to replace emotional, psychological, health or social-care services. It is to provide practical, compassionate support alongside them, helping create the foundations from which they can begin to move forward.
Kayleigh studied Child Psychology, Health and Nutrition, and Health and Social Care at Barry College in 2004, later continuing her education with Psychology and Social Science through the Open University, alongside Health and Social Legislation and Business Management. She also ran a cleaning company, building more than 20 years of practical experience across a range of roles.
Having faced mental health difficulties herself, Kayleigh feels the time is right to give back to the community as one of their own. Mundus is her way of turning lived experience, practical know-how and formal learning into respectful, person-centred support for others.
Mundus is registered as a Community Interest Company, meaning its purpose is community benefit first. That purpose drives everything from the way support is delivered to the way income is reinvested.
What drives Mundus
Person-centred from the start
Mundus was built around the belief that people do best when support is shaped around their own goals, values and circumstances.
Practical, not clinical
The focus is on everyday life: home environments, routines, confidence, independence and community connection — without clinical labels or time-pressured visits.
A social-enterprise vision
As a Community Interest Company, Mundus reinvests surplus back into community benefit, training and subsidised support where funding allows.
Rooted in Cardiff and the Vale
Support is offered across Cardiff and the Vale of Glamorgan, with an emphasis on local knowledge, accessibility and genuine relationships.
