As a charity, we're not here to profit from fostering
Tough decisions have to be made when profits are on the line and there are shareholders to please. That's where Diagrama Fostering is different from other foster agencies. As a not-for-profit organisation any ‘profit’ from our fostering service is ploughed straight back into ensuring our foster carers and the children in our care are supported in the best way possible. So we can genuinely, hand on heart, say we put children at the heart of everything we do and every decision we make, without commercial distractions.
"Children have positive and secure relationships with the adults who care for them.
Foster carers demonstrate a high level of care and commitment to children who they view as part of the family".
Ofsted inspection, 2023
Why foster carers choose to work with Diagrama
Finding the right foster agency to suit your needs is important. You want a team that will be solution-focused and there to support you 24/7. As a progressive, genuinely caring and completely child-focused agency, Diagrama foster carers are highly valued members of our team who receive dedicated support and comprehensive training. Our carers are assigned a dedicated supporting social worker who is there to guide them through every step of their placement.
Many local authorities across the UK request foster care placements from Diagrama Fostering, which means we are able to identify placement matches that work for you and your family needs. That way we know you will have the best chance of having a positive impact on the child’s future. We are particularly interested in carers who can consider long-term and parent and child placements.

“We chose to foster so that we could make a difference. Inviting another child into your home and allowing them to find some stability, come alive and begin to really thrive is the best family decision we have made, and I couldn’t recommend it highly enough.”
