C2 residential institutions or C3 dwellings: care schemes
Extra care and assisted living schemes sit on the boundary between Class C2 and Class C3. This sets out how councils decide, what evidence they want, and what follows from the answer.
A care scheme falls within Class C2 where residential accommodation and care are provided together to people in need of care, and within Class C3 where the occupants live in dwellings and any care is an add-on rather than the reason the accommodation exists. The Use Classes Order gives no formula. It is a question of fact and degree, decided on the care package, the physical form of the units and the way the scheme is run.
The answer is worth arguing about, because affordable housing policy, levy liability and housing land supply all follow from it.
What separates the two classes in practice
Class C2 covers the provision of residential accommodation and care to people in need of care, other than uses falling within Class C3, along with hospitals, nursing homes and residential schools, colleges and training centres. A care home with shared dining, a staffed base and bedrooms rather than flats is plainly C2.
Class C3 covers dwellinghouses, whether occupied by a single person, by a family, by up to six people living together as a single household where care is provided, or by up to six sharing without care. That third limb is what accommodates small supported living houses.
The difficulty lies between those poles. A development of 70 self-contained one and two bedroom flats, with a restaurant, a residents' lounge, a wellbeing suite and a care team on site, has features of both. The council will look past the marketing brochure to what is actually being sold and how the occupants live.
Extra care and assisted living on the boundary
Officers tend to work through a familiar list of questions.
Are the units self-contained, with their own kitchen, bathroom and lockable front door? Self-contained units point towards C3.
Is there a minimum assessed care need for occupation, and is a care package mandatory rather than optional? A requirement that every resident takes a minimum number of hours of care each week points towards C2.
Is the care provider registered with the Care Quality Commission for that setting, and is the registration for personal care in a residential setting or for domiciliary care delivered to people in their own homes? Registration type is strong evidence, though it is not determinative in planning terms.
Are communal facilities on a scale that only makes sense with an integrated care operation, or are they the sort of shared amenity any retirement flat scheme would offer?
Is the accommodation sold on long leases and freely resaleable, or licensed with occupation tied to continuing care? A freely saleable long lease with no care tie is hard to present as C2.
No single answer decides it. A scheme with self-contained flats, mandatory care of a stated minimum and occupancy conditions tied to assessed need has been accepted as C2 in many authorities. Remove the care tie and the same building is C3.
The care package and the degree of independence
The most useful distinction is whether the accommodation exists so that care can be delivered, or whether care is being delivered to people who happen to live there.
Ask what happens if a resident's care need falls away. In a C2 scheme, they would be expected to leave, because the accommodation is tied to the need. In a C3 scheme they simply stop buying care and stay put. That thought experiment usually settles the classification faster than any amount of policy citation.
Watch the staffing model too. A twenty-four hour on-site care team with a staff base, sleep-in accommodation and a call system in every unit supports C2. A visiting service with a scheme manager working office hours does not.
Why the classification changes what a scheme owes
| Class C2 | Class C3 | |
|---|---|---|
| Affordable housing | Often outside the standard policy, though many plans now apply a specialist policy or a commuted sum | Standard policy applies from the local threshold upwards |
| Levy liability | Charging schedules commonly set a different rate, sometimes nil, for C2 | The residential rate in the charging schedule applies |
| Housing land supply | Counted using a ratio based on average household size, following national guidance | Counted unit for unit |
| Space standards | The nationally described space standard applies to dwellings, so not directly | Applies where the council has adopted it |
| Parking and transport | Assessed on staff and visitor trips as well as residents | Assessed on resident car ownership |
Those consequences pull in opposite directions for applicant and council, which is why C2 claims attract scrutiny. A developer arguing for C2 to avoid an affordable housing contribution should expect the council to test the care evidence hard, and to secure the position by condition or obligation if it accepts the argument. A useful Affordable Housing Statement deals with the classification question head on rather than assuming the answer.
Check the charging schedule rather than assuming. Levy rates and any relief for institutional uses are set locally and revised periodically, so read the current schedule on the council's website.
Evidence councils ask for
Put this in the application rather than waiting to be asked.
- A written description of the care model, including minimum care hours, how needs are assessed and who provides the care.
- The intended registration with the Care Quality Commission, naming the regulated activity.
- Draft heads of terms for the occupancy agreement or lease, showing the care tie.
- A schedule of communal facilities with floor areas, showing what is actually shared.
- Staffing numbers by shift, which also feeds the transport work.
- A statement of local need, drawn from the council's own evidence base on older people's housing where one exists.
That last point matters more than applicants expect. Where a council has identified a shortfall in specialist older people's accommodation in its plan evidence, quoting its own figures back is far stronger than generic demographic argument.
Conditions tying occupation to a care need
Where a council accepts C2, it will normally impose a condition restricting occupation to people meeting a defined care need, often expressed as an assessed need for a minimum number of hours of care per week, sometimes combined with an age threshold. A section 106 obligation may run alongside it where the restriction needs to bind successors in title more securely.
Read the wording carefully before it is imposed. A condition requiring a minimum care package that the operator cannot deliver commercially becomes unenforceable in practice and awkward at sale. Negotiate the number while the application is live, not after.
When a scheme changes character after occupation
Classification is not fixed for ever. Where care ceases and units are sold on the open market, the use may have changed materially, and the council can take enforcement action or invite a fresh application. The related question of what unit of land or building the council assesses is covered in the article on the planning unit and how councils decide what they assess, and the fuller treatment of the two classes in supported housing sits in care homes and supported housing: C2 or C3.
For a scheme being planned now, set out the classification argument in the Planning Statement with the care evidence attached, rather than leaving the officer to infer it from a floor plan.

Frequently asked questions
Are self-contained flats automatically Class C3?
No, though self-containment points that way. Councils weigh the whole picture, including whether care is mandatory, whether occupation is tied to an assessed need, the scale of communal facilities and the staffing model. Extra care schemes of self-contained flats are regularly accepted as C2 where the care tie is real and secured by condition.
Does a C2 scheme pay affordable housing contributions?
It depends on the adopted plan. Many affordable housing policies are framed around C3 dwellings, so a C2 scheme falls outside them, but an increasing number of plans apply a specialist housing policy or seek a commuted sum from C2 development. Read the policy wording and the supporting text rather than assuming an exemption.
How is a care home counted towards housing land supply?
National guidance explains that accommodation providing care can be counted using a ratio based on average household size, rather than unit for unit. Councils apply this differently, and the approach has been tested at appeal. Check the current guidance wording and the council's own housing trajectory methodology before relying on a particular figure.
Is Care Quality Commission registration decisive for the use class?
No. Registration is strong evidence of the care model and the type of setting, and planning officers ask for it, but the use class is determined by planning law on the facts of the case. A scheme can be registered for domiciliary care and still be argued either way depending on the occupancy arrangements.
What happens if care stops being provided after the scheme opens?
The use may have changed materially, which would need permission. Councils guard against this with occupancy conditions or a section 106 obligation tying units to residents with an assessed care need. Where units are sold on without the tie, the authority can investigate and take enforcement action within the statutory time limits.
