About Diagrama Fostering

A charitable agency delivering a personalised, meaningful fostering experience that isn't focused on profits

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.”

Chris and Nic Kimmance 

Our Values

Fostering a child can have a life-long impact on everyone involved. As we support our foster carers on that journey we adopt the following values:

  • We’re committed - Our foster carers receive excellent training and we ensure they are fully prepared for their role, with realistic expectations, able to offer a positive, stable and nurturing environment. Our committed approach extends to our foster carers who stick by their foster children, even when times are tough.
  • We offer support every step of the way – We know fostering can be challenging - that’s why we provide comprehensive, round-the-clock support. No problem is ever too small and our foster carers never need feel on their own.
  • We’re passionate – We aim to achieve the best outcomes for children, with our team often going beyond the call of duty. This is reflected in our retention rates, our Ofsted report and our impressive educational achievement record.
  • We strive for excellence – We know that to offer a service of excellence, with outstanding outcomes, our learning is never done. We believe in working collaboratively, sharing best practice and investing in the development of our exceptional team, providing expert training and support, with quality and safeguarding at the forefront of our minds.
  • We invest our funds responsibly - As part of the charity Diagrama Foundation, we ensure our funds are used where it matters the most – directing any ‘surplus’ into supporting our foster carers and ensuring the child or young person receives excellent care.
  • We only recruit the best - Our robust vetting process ensures we recruit the most dedicated foster carers for society’s most vulnerable children. After all, it’s the least they deserve. We welcome enquiries from people from all walks of life and with a wide range of experiences.

“After looking at various agencies we chose the charity Diagrama and dipped our toe into fostering by  attending one of their information evenings, where we were able to ask as many questions as we wanted.”
