Children’s home planning: C2 or C3?

Understand why the operation of a children’s home matters when choosing between a planning application and a lawful development certificate.

General guidance for England. The route depends on your property and proposal. Preparation checklists are our suggested starting points, not exhaustive legal requirements.

Start with the operation, not a bedroom count

A children’s home is not classified solely by how many bedrooms it has. C2 and C3 describe different planning uses; whether a proposal involves a material change is a separate, fact-sensitive question. National guidance on changes of use explains the general framework.

Sandwell’s children’s home guidance illustrates why resident numbers, staffing arrangements, movements and effects on neighbours matter. Its local examples are not national thresholds or guarantees.

Describe a normal week

Our suggested starting point is a short operating brief. Set out the intended maximum number of children, who provides care, where staff live, shift handovers and expected visitor arrangements. Explain the proposed use of every room and any changes to the building.

Keep the description consistent across the operator’s brief, drawings and application documents. If the operating model is still changing, identify what remains undecided rather than presenting assumptions as fixed facts.

Choose the application that answers the question

A lawful development certificate considers lawfulness, not whether a proposal is desirable. A proposed-use application needs a precise description and supporting evidence. A full planning application addresses a different question: whether permission should be granted. See government guidance on lawful development certificates.

Prepare for an initial discussion

  • Property address and any planning decisions or conditions.
  • An outline operating brief with staffing and occupancy.
  • Existing plans, proposed alterations and parking arrangements.

Ask for advice on the proposed operation as a whole. A statement that another two-child home was accepted elsewhere does not establish the position for your property.
