How to Become a Foster Carer in the UK: Full 2025 Guide

Deciding to become a foster carer is a meaningful way to help children who need a safe and supportive home. This guide explains every step you need to know, from eligibility and assessment to support, payments and local opportunities in London and surrounding areas.

What fostering is and who it helps

Fostering is a form of temporary care where a child is placed in a family that is not their own. The child remains the property of the local authority and is supported by a social worker. Foster carers provide a stable, nurturing environment while the child’s legal and emotional needs are addressed.

Children who are fostered may have experienced neglect, abuse or family breakdown. Some are awaiting adoption, while others may stay for a short period during an emergency. In London, the demand for foster placements is high, especially in East and South East London where many children are waiting for a permanent home.

Benefits and responsibilities of foster carers

Emotional rewards

Foster carers often report a deep sense of fulfilment. They help children build confidence and resilience, and they create lasting bonds that can transform both the child’s and the carer’s life.

Practical responsibilities

Foster carers are expected to:

• Provide food, clothing and accommodation that meet the child’s needs.
• Ensure the child’s safety and well‑being at all times.
• Support the child’s education, health and social development.
• Communicate regularly with the social worker and any other professionals involved.

Eligibility and assessment process

Who can apply

There are no strict age limits, but most local authorities prefer carers who are at least 21 years old. Applicants must be fit and suitable, meaning they have no serious criminal convictions, no history of domestic abuse and no ongoing health issues that would compromise the child’s safety.

Initial application

To begin, you must complete a brief application form available from your local authority or an independent fostering agency. The form asks about your background, family situation, and motivation for fostering.

Assessment stages

The assessment process typically involves:

1. Pre‑assessment interview with a social worker.
2. Home visit to check the suitability of your environment.
3. Background checks, including DBS, health checks and financial assessment.
4. Reference checks from employers, neighbours or community leaders.

During this period, you may be asked to attend an information session about what fostering involves.

Support, training and supervision provided

Training programmes

All new foster carers receive initial training covering child protection, health and safety, and the legal framework of fostering. In London, the local authority often offers a mandatory 20‑hour induction, followed by ongoing training modules.

Ongoing supervision

Once a child is placed in your home, a social worker will conduct regular visits. These visits are designed to support you, discuss any challenges and ensure the child’s welfare is protected. Many agencies also provide a peer support network where carers can share experiences and advice.

Allowances and payment structure explanation

According to official UK fostering guidance and local authority policies, foster carers receive a monthly allowance that covers the cost of living the child. The amount is not fixed; it is calculated based on the child’s age, special needs and the length of the placement. In addition to the basic allowance, carers may receive extra payments for:

• Special educational requirements.
• Health or medical support.
• Travel and transport costs.
• Holiday and leisure activities.

All payments are made directly to the carer’s bank account and are subject to a review by the local authority.

How to apply for fostering in London

Step 1 – Find a local authority or agency

In London, you can choose between the borough council’s fostering service or an independent fostering agency. Both offer similar support, but the application process may differ slightly. For example, the latest foster care shortage in the UK report highlights that many London boroughs have waiting lists, so early application is advisable.

Step 2 – Complete the application form

Download the form from the council’s website or the agency’s portal. Fill it out accurately and return it with any supporting documents such as proof of address and identity.

Step 3 – Attend an information session

Most councils hold a mandatory session where you learn about fostering responsibilities, the support available and the assessment process. This is also a good opportunity to ask questions.

Step 4 – Undergo the assessment

Once your application is accepted, a social worker will schedule the assessment stages outlined earlier. Be prepared to provide references and to discuss how you would support a child’s emotional and educational needs.

Step 5 – Receive approval and begin training

After a successful assessment, you will receive a formal approval letter. You will then enrol in the induction training programme, which can take a few weeks.

Local fostering context and agencies including nearby areas

London boroughs

Each London borough operates its own fostering service. For instance, the borough of Hackney has a dedicated fostering team that focuses on supporting children with complex needs. Meanwhile, Southwark offers a range of placements, from short‑term to long‑term, and specialises in therapeutic fostering.

Independent fostering agencies

There are several reputable agencies that operate across London and its outskirts. They often provide more flexibility in placement types and can offer specialist placements such as for children with autism or for those who need intensive care.

Nearby areas

Foster carers based in London can also apply to agencies covering East London, North London and South East London. These regions often have a high demand for foster placements and may offer additional training or support for carers who work across borough boundaries.

Common challenges and realistic expectations

Time management

Balancing work, family and fostering duties can be demanding. Many carers find that they need to adjust their schedule or seek flexible working arrangements.

Emotional resilience

Children in care often carry complex histories. Carers may experience emotional fatigue, especially during the initial weeks of a placement. Ongoing supervision and peer support are vital to manage stress.

Financial planning

While allowances cover many costs, carers may still face unexpected expenses such as medical supplies or educational materials. It is wise to budget for these possibilities.

Legal responsibilities

Foster carers must adhere to child protection laws and the safeguarding framework. Failure to do so can result in the removal of the child or legal action.
