C2 and C2A: care homes, hostels and secure institutions

Class C2 use covers residential accommodation and care for people in need of care, hospitals and nursing homes, and residential schools, colleges and training centres. Class C2A covers secure residential institutions: prisons, young offenders institutions, detention and custody centres, secure hospitals and military barracks. Both sit apart from Class C3 housing, and moving between them needs planning permission.

The line that matters commercially is not between C2 and C2A. It is between C2 and C3, because that boundary decides whether a scheme is assessed as housing, with everything that follows for affordable housing, and whether it counts towards the council's housing supply.

What Class C2 covers and the care element

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. That definition does the heavy lifting.

Three activities fall within C2. Residential accommodation and care provided together, which is the classic care home. Use as a hospital or nursing home. And use as a residential school, college or training centre, which is why a boarding school is C2 rather than C3.

Personal care means help with the ordinary activities of daily living: washing, dressing, eating, medication. Housekeeping, a warden service, a pull cord and a communal lounge are support rather than personal care, and a scheme offering only those is unlikely to be C2 however it is marketed.

The registration position is evidence but not the answer. A scheme registered with the care regulator for personal care is on strong ground, and a scheme not registered has to explain how care is delivered. Planning classification and regulatory registration are separate systems, and officers know that.

Where a care home becomes C3 supported living

The exclusion in the Order is precise. Class C3 covers not more than six residents living together as a single household where care is provided. A small care home for up to six people who do live as one household is C3, not C2.

Above six residents, the single household analysis usually fails and the use is C2. Below it, the question is whether the residents live as a household: shared meals, shared living space, a communal way of life, some permanence.

Supported living schemes are where the argument bites hardest. Where each resident holds their own tenancy, has their own front door and kitchen, and receives visiting support rather than on-site personal care, the units look like independent flats and the use is closer to C3. Where residents share facilities, staff sleep in, and care is delivered on site around the clock, C2 is the better fit.

Get this wrong in the description of development and the consequences run for years. A scheme consented as C2 that operates as independent flats is vulnerable to enforcement and to a challenge over the affordable housing contribution it avoided.

Class C2A and secure residential institutions

C2A was created to separate secure institutions from ordinary residential institutions, because the planning issues are different.

The class covers prisons, young offenders institutions, detention centres, secure training centres, custody centres, short term holding centres, secure hospitals, secure local authority accommodation and military barracks. Movement between C2 and C2A is a change of use requiring permission in both directions.

Applications in this class are dominated by matters that barely feature elsewhere: perimeter security and its visual effect, staff parking and shift change traffic at times outside the normal peaks, visitor transport, lighting to security standards rather than amenity standards, and emergency access. Community concern is usually the largest single issue, and a Statement of Community Involvement that documents genuine engagement rather than a leaflet drop carries weight at committee.

Custody suites attached to police stations and short term holding facilities at ports are the smaller end of this class and often overlooked in feasibility work.

Student halls and where they sit

Purpose-built student accommodation does not have its own class, and practice varies between authorities.

Where the accommodation is provided by an educational institution as part of a residential college, C2 is arguable. Where it is speculative accommodation let to students of any institution, with cluster flats and a management company, most authorities treat it as sui generis, and many local plans now contain a specific policy for it.

That matters because sui generis means every change needs permission, including a later conversion to conventional housing or to serviced accommodation. It also means the local plan policy on student accommodation applies directly rather than by analogy, including any requirement for a nomination agreement with a named institution.

Check the authority's practice before drafting a description of development. Two neighbouring boroughs commonly classify the same building type differently, and the description you use frames the whole assessment.

Policy tests for loss and gain of C2 floorspace

Councils apply policies in both directions.

Losing a care home to housing engages policies protecting community and health facilities. The usual evidence requirements mirror those for other community uses: marketing at a realistic price for a defined period, evidence that the facility is not viable, and evidence that need is met elsewhere in the area. An ageing population makes that a hard case in most districts.

Gaining C2 floorspace engages a different set of questions. Whether the scheme meets an identified local need, which is set out in the council's older persons housing evidence base. Whether the site is accessible to health services, shops and public transport. Whether the design meets accessibility standards. And how the scheme is treated for housing supply purposes, which is usually done by converting bedspaces into dwelling equivalents using a published ratio.

Affordable housing is the contested point. Whether a C2 scheme contributes depends on the local plan policy and on how the authority treats institutional accommodation, and it is worth resolving at pre-application rather than at the section 106 stage.

Parking, staffing and amenity considerations

Care schemes generate traffic patterns that standard trip rates handle badly.

Staff arrive and leave at shift changes, often at 7am, 2pm and 10pm, which falls outside the network peaks the highway authority usually assesses. Visitor traffic concentrates at weekends and early evenings. Deliveries include laundry, catering and clinical waste, each on its own cycle. And ambulance access has to be designed for, with a route to a covered entrance that does not require reversing.

A Transport Statement for a care scheme should model those patterns rather than applying a generic residential rate, and should set out staff parking based on the actual rota rather than bed numbers.

Amenity works in both directions. Residents need private outdoor space with shelter and level access, and the scheme needs protection from external noise, which on a site near a road or a commercial use means a Noise Impact Assessment addressing internal levels and external amenity space. Plant noise from kitchens, laundries and ventilation is the part most often forgotten, and it is the part neighbours complain about.

Evidence for a C2 change of use application

For a change of use into C2, expect to submit a description of development naming the class and the care model, a Planning Statement addressing local need and the policy tests, a care model statement explaining staffing levels and the personal care provided, a transport statement covering shift patterns and ambulance access, an accessibility statement against the relevant standards, and noise and plant details.

For a change out of C2, add the marketing evidence, viability material and an assessment of need in the area, drawn from the council's own evidence base rather than a general assertion.

Where the classification itself is arguable, put the analysis in writing at pre-application stage and ask for a view. A written response from the authority is not binding, and it is far better than discovering the disagreement after validation.
