The Key Difference

The fundamental difference between fostering and adoption is legal responsibility. When you foster a child, the local authority retains legal parental responsibility. When you adopt, that responsibility transfers permanently to you — the child becomes a legal member of your family, just as if they had been born to you.

Fostering can be short-term or long-term, and the aim is often for children to return to their birth family when it is safe to do so. Adoption is permanent and irreversible — once an adoption order is granted, the legal relationship with the birth parents ends and you become the child’s parent in every legal sense.

Both routes are vital. Some children need the stability of a permanent adoptive family; others need the safety and care of a foster home while their long-term plan is decided. Many people start by fostering and later go on to adopt, but they are separate legal processes.

Why Choose Fostering?

Fostering offers unique benefits and the chance to help multiple children over your career

💰

Financial Support

Foster carers receive a weekly allowance plus a skills-based fee, typically £450–£860 per week from IFAs. Most income is tax-free under Qualifying Care Relief. Adoptive parents do not receive ongoing fees.

Why Choose Adoption?

Adoption is the right choice for people who want to build a permanent family. When you adopt, the child becomes yours in every legal and emotional sense. You make all the decisions about their upbringing, education, health and future — just as any parent would.

Adoption is particularly suited to people who want to be a parent permanently and are ready for the lifelong commitment that comes with it. Many children who are adopted are younger, though older children and sibling groups are also waiting for adoptive families.

Adoptive parents are entitled to statutory adoption leave and pay (up to 52 weeks, similar to maternity leave). An Adoption Support Fund is available to help with therapeutic services if needed after placement.

Can I Foster and Adopt?

Yes. Many people start by fostering and later go on to adopt a child they have been caring for. This is sometimes called “fostering to adopt” or “concurrent planning.” It allows you to provide early permanence for a child while their care plan is being finalised.

If a child’s plan changes to adoption and you have been their foster carer, you may be considered as the adoptive parent. This is not guaranteed, but courts recognise the value of stability and existing attachments when making placement decisions.

Some people foster for years before deciding adoption is right for them. Others know from the start that they want to adopt. There is no wrong path — both make an extraordinary difference to children’s lives.

Fostering vs Adoption: Common Questions

Answers to the most frequently asked questions about the differences between fostering and adoption.

The main difference is legal responsibility. In fostering, the local authority retains legal parental responsibility for the child. In adoption, full legal parental responsibility transfers permanently to the adoptive parents. Fostering can be temporary or long-term, while adoption is permanent and irreversible.

Foster carers work as part of a professional team alongside social workers and receive ongoing support, training and a weekly allowance. Adoptive parents take on full independent parental responsibility, similar to having a birth child.

  • fostering temporary adoption permanentFostering can be temporary; adoption is permanent
  • fostering support ongoingFoster carers receive ongoing professional support and allowances
  • adoption parental rightsAdoptive parents have full independent parental responsibility

Yes, generally. Foster carers receive a weekly fostering allowance plus a skills-based fee throughout the placement. From independent agencies, this typically totals £450 to £860 per week per child, and most of this income is tax-free under Qualifying Care Relief.

Adoptive parents may receive an adoption allowance in some cases, particularly where the child has additional needs, but this is means-tested and typically lower than fostering payments. There is no ongoing fee for adoptive parents. However, adoptive parents are entitled to statutory adoption leave and pay.

Yes, this is possible and does happen. If a child’s care plan changes from foster care to adoption, the foster carer may be considered as the adoptive parent, particularly where a strong bond has formed. This is sometimes called “fostering to adopt” or concurrent planning.

However, it is important to understand that not every foster placement leads to adoption. The decision depends on the child’s care plan, the court’s assessment of what is in the child’s best interests, and whether adoption is the right permanent arrangement for that child.

Becoming a foster carer typically takes 4 to 8 months from initial enquiry to panel approval. This includes a preparation course and a Form F assessment carried out by a social worker. If you are an experienced carer transferring agencies, it can be fast-tracked to around 12 weeks.

The adoption process generally takes longer, typically 6 to 12 months or more. It includes a two-stage process: Stage 1 involves checks and references (about 2 months), and Stage 2 is the detailed assessment and Prospective Adopter’s Report (about 4 months), followed by matching with a child which can take additional months.

Foster carers receive a comprehensive, ongoing support package that continues throughout every placement. This typically includes a dedicated supervising social worker, 24/7 out-of-hours helpline, regular supervision meetings, ongoing training and professional development, peer support groups, and planned respite care.

Adoptive parents can access the Adoption Support Fund for therapeutic services, and some adoption agencies offer post-adoption support. However, the level of ongoing, day-to-day professional support is generally less than in fostering, because the adoptive parents have full independent parental responsibility.

It depends on the individual case. Many adopted children have “letterbox contact” — exchanging letters or updates with birth family members once or twice a year, managed through the adoption agency. Direct face-to-face contact is less common in adoption but is increasingly being considered where it is in the child’s interests.

In foster care, contact with birth family is more frequent and is usually a structured part of the care plan. Foster carers are expected to support and facilitate regular contact visits, which may be supervised by social workers. This is one of the practical differences between fostering and adoption.

  • fostering contact birth familyFoster care usually includes regular supervised contact visits

  • fostering contact supportFoster carers support and facilitate contact as part of the care plan

Both fostering and adoption involve a thorough assessment process, but neither is designed to be unnecessarily difficult. The assessments are there to ensure children are placed with safe, capable and well-prepared families. Most people who start either process go on to be approved.

The fostering assessment (Form F) typically takes 4–6 months. The adoption assessment (Prospective Adopter’s Report) follows a two-stage structure over 6 months or more. Both involve home visits, interviews, references, health checks and DBS checks. The key difference is that adoption also involves a court process to grant the adoption order.
