What is the 'usual fostering limit'?

Schedule 7 of the Children Act 1989 limits the number of children who may be fostered by a foster carer. The “usual fostering limit” is set at 3. This means that no one may foster more than 3 children unless: 

  • The foster children are all siblings in relation to each other
  • Exemptions can only be granted by the local authority within whose area the foster carer lives, and only in relation to specific foster children who are currently living with the foster carer (in which case they must set out the terms as detailed below), and
  • The foster carer’s terms of approval allow it (any terms of approval must be compatible with the number of children the foster carer is caring for even if an exemption to the usual fostering limit has been granted, unless it is an emergency and for less than 6 days)
  • A local authority cannot grant an exemption to the usual fostering limit to a foster carer living outside of its area 

The local authority must have regard to a number of factors when considering an exemption from the usual fostering limit. When a local authority does exempt a person from the usual fostering limit, it must notify the carer in writing.  

An exemption is not time limited unless a time limit is set as a condition of the exemption being granted. A local authority may vary, cancel, or amend the exemption at any time, by giving notice in writing.

Granting an exemption

The local authority should nominate an officer with delegated powers to grant exemptions from the usual fostering limit. They should ensure that fostering services and independent fostering agencies operating within the area are aware of the procedures to be followed in requesting such exemptions.

A person who either exceeds the usual fostering limit, or if exempted fosters a child who is not named in that exemption, is regarded as carrying on a children’s home for the purposes of the 1989 Act and the Care Standards Act 2000, and so needs to be registered as such with Ofsted.

A child who is not looked after does not count towards the usual fostering limited (e.g. a birth child, an adopted child, or a child on a Special Guardianship Order (SGO). Nevertheless, the needs of all children in the household must be considered in deciding whether to grant an exemption from the usual fostering limit.

Exemptions with an Independent Fostering Agency

If you are fostering with an Independent Fostering Agency (IFA), the local authority in whose area you live is responsible for granting any exemption. This is despite a different local authority making the placement with the foster carer through the IFA.

Sibling groups

An exemption is always required when more than 3 unrelated children are being placed in one household. All children, whether part of a sibling group or not, count as individual children. 

For example, a sibling group of 4 children who are not living with any other foster children would not require an exemption, as they are all related to each other. However, two sibling groups of 2 children would require an exemption, because they are not all related.
