Children's homes: C2 or C3 under the Use Classes Order
Small children's homes are often Class C3 dwellinghouses rather than C2 institutions. The head count, the single household test and the statutory meaning of care decide it.
A children's home for up to six young people, run as a single household, is very often a Class C3 dwellinghouse and needs no change of use permission at all. Councils frequently assume the opposite, because the word "home" in the care sense suggests an institution. The Use Classes Order does not work that way. What governs is the number of residents, whether they live together as a single household, and the precise statutory meaning of care, which for children is narrower than most people expect.
Getting this right matters because the alternative to a correct reading is an unnecessary application, an avoidable refusal, or an enforcement notice that could have been answered with a certificate.
How the Use Classes Order treats care
The Town and Country Planning (Use Classes) Order 1987 splits residential care across two classes.
Class C2 covers the provision of residential accommodation and care to people in need of care, other than a use within Class C3. It also covers hospitals, nursing homes and residential schools, colleges and training centres.
Class C3 covers dwellinghouses. It has three limbs. C3(a) is use by a single person or by people living together as a family. C3(b) is use by not more than six residents living together as a single household where care is provided to residents. C3(c) is use by not more than six people living together as a single household where no care is provided, which picks up religious communities and some small supported arrangements.
Two numbers do the heavy lifting. Six residents is the ceiling for C3(b) and C3(c). And the single household requirement is a test in its own right, separate from the head count, which means seven residents living as one household is still outside C3 and five residents in five self-contained units is also outside it.
The definition of care and why it matters for children
Article 2 of the Order defines care as personal care for people in need of it by reason of old age, disablement, past or present dependence on alcohol or drugs, or past or present mental disorder. It then adds that in Class C2 care also includes the personal care of children and medical care and treatment.
Read that twice. The personal care of children is written into the C2 definition and is not written into the general definition that C3(b) relies on. So a child who is looked after because of family circumstances rather than disability or mental disorder is not necessarily receiving care within the C3(b) meaning at all.
The practical consequence is counterintuitive but well established in appeal decisions. A small children's home is frequently analysed as falling within C3(a) or C3(b) depending on how the household operates, and inspectors have repeatedly found that a household of up to six young people with resident or shift carers, sharing meals, living space and a front door, is a single household in planning terms. Where that is the position, there is no material change of use from a family dwelling and no permission is needed.
Where the children do have disabilities or diagnosed mental disorder, the general definition of care is engaged and C3(b) applies directly, still subject to the six-resident ceiling and the single household test.
Where a small home stays in C3
The single household question is the one that gets argued, and it turns on how the property actually operates rather than on the label above the door.
| Indicator | Points towards a single household | Points away from it |
|---|---|---|
| Front door and circulation | One shared entrance, shared hall and stairs | Separate entrances or lockable self-contained units |
| Kitchen and dining | Shared kitchen, meals taken together | Individual kitchenettes, no communal meal |
| Living space | Shared sitting room in regular use | Bedsit arrangement with no communal room |
| Staff presence | Carers living or sleeping in, integrated into the household | Staff base or office visited in shifts with no household role |
| Length of stay | Months or years, the young person's home | Short assessment placements measured in days |
| External appearance | Indistinguishable from a family house | Signage, staff parking bays, institutional fit-out |
Solo placements are the difficult case. A single young person with two or three staff on rotating shifts can look more like a staffed unit than a household, and several inspectors have said so. If that is the model, take a certificate rather than assuming the answer.
Section 192 of the Town and Country Planning Act 1990 allows an application for a lawful development certificate for a proposed use. It is the only formal route to confirm that a use is lawful, and on a children's home it often costs less than a change of use application, because the question is legal rather than a matter of planning judgement.
When the use tips into C2 or sui generis
Three changes move the use out of C3. Taking a seventh resident. Reconfiguring the house so residents no longer live as a single household. And introducing a level of medical care and treatment that takes the use towards a residential institution.
Where the use is neither C3 nor a comfortable fit with C2, it can end up outside the classes altogether, which brings the flexibility and the limits described in sui generis uses that belong to no class at all. The same boundary comes up in adult provision, and the reasoning is set out at more length in supported living, care homes and the C2 to C3 line.
A change from C3 to C2 is a material change of use requiring permission. There is no permitted development right for it. And a change from C2 back to C3 is also development, so a property that has operated lawfully as a C2 home for years does not automatically revert.
Amenity, staffing and vehicle movements
Where an application is needed, the objections follow a familiar pattern and none of them is about the children.
Parking and shift changes come first. A home with three staff on days, two on nights and a handover period generates more vehicle movements than a family house, concentrated at the same times each day. Set out the staffing rota, the number of staff vehicles expected on site at once, and where they park. A short Transport Statement is proportionate for most of these schemes and heads off the highway objection.
Then comes noise and disturbance, usually raised by neighbours in general terms. The planning answer is that the use is residential and the relevant comparison is a family household of the same size, not an institution. Deliveries, waste collection and any minibus should still be addressed, because those are real differences.
Finally, external alterations. Wheelchair ramps, additional hardstanding, fencing and a garden building are each separately assessable, and a scheme that keeps the exterior indistinguishable from neighbouring houses removes most of the visual objection at a stroke.
Ofsted registration is a separate regime
Children's homes in England are registered and inspected by Ofsted under the Care Standards Act 2000 and the Children's Homes (England) Regulations 2015. That regime sets standards for accommodation, staffing ratios, the statement of purpose and safeguarding.
It has no bearing on the use class. Registration does not create a need for planning permission, and planning permission does not satisfy registration. Councils occasionally suggest that a registered home must be C2 because it is regulated, which confuses two separate statutory schemes. Say so politely and in writing.
What registration does give you is useful evidence. The statement of purpose describes the number of places, the staffing model and the length of placements, which is exactly the material a planning officer needs to assess the single household question.
Evidence to submit and conditions to expect
Whether you are applying for a certificate or for permission, put the same material in front of the officer. A floor plan showing shared kitchen, dining and living space and the absence of self-contained units. The proposed maximum number of young people. The staffing rota with numbers on site at each point in the day. The expected length of placement. The parking arrangement with a swept path if access is tight. And a short management plan covering deliveries, waste and external maintenance.
A Planning Statement that walks through the Use Classes Order definitions in order, applies them to the actual operating model and states the conclusion is worth more than a long document about need. Officers respond to structure here.
Expect conditions limiting the number of residents, tying the use to the submitted management plan and sometimes restricting external alterations. A condition capping resident numbers at six is reasonable and normal. A condition naming a specific operator usually is not, since conditions should regulate the use of land rather than its occupier, and that is worth challenging at the draft stage rather than after grant.

Frequently asked questions
Is a children's home automatically Class C2?
No. Class C3(b) covers up to six residents living together as a single household where care is provided, and C3(a) covers people living together as a family. Many small children's homes operate as a single household and fall within C3, meaning no change of use permission is needed. The head count and the household arrangement decide it, not the label.
What does care mean in the Use Classes Order?
Article 2 defines care as personal care for people in need of it by reason of old age, disablement, dependence on alcohol or drugs, or mental disorder. It adds that in Class C2 only, care also covers the personal care of children and medical care and treatment. That difference is why the C3 analysis of a children's home is not as obvious as it looks.
How do I prove the use is lawful without applying for permission?
Apply for a lawful development certificate for a proposed use under section 192 of the Town and Country Planning Act 1990. It is the only formal way to confirm lawfulness. Submit floor plans showing shared living space, the proposed maximum number of young people, the staffing rota and the expected length of placements.
Does Ofsted registration affect the use class?
No. Registration under the Care Standards Act 2000 and the Children's Homes (England) Regulations 2015 is a separate regime with its own standards. It neither creates nor removes a need for planning permission. The statement of purpose is useful planning evidence, because it sets out places, staffing and placement length in one document.
Are solo placements treated differently?
Often, yes. One young person supported by two or three staff on rotating shifts can look more like a staffed unit than a household, and inspectors have taken that view on the facts. Where that is the operating model, apply for a certificate rather than assuming the C3 position holds.
