Class V: flexible planning permission explained

 

Is this just a full planning application?

 

At the first stage, yes. An owner who does not already have the necessary permission can make a full planning application for flexible use. The application must identify the alternatives clearly, and the decision-maker considers whether the proposed flexibility is acceptable on its planning merits.

This is not an application for Class V prior approval. Mentioning Class V does not create an entitlement to permission or remove the need to address the development plan and other material considerations.

Class V matters at the second stage. Where its requirements are met, it grants permitted development for a later change from one authorised use to another. A fresh full application is not required simply to repeat that assessment for each qualifying switch.

Where a suitable express permission already exists, the owner may be able to use Class V without a new application. But a permission for one use alone is not automatically a permission for flexible use.

 

Why two Durham flexible-use applications split

 

Our comparison of two Durham HMO appeals shows both stages in practice. The same Inspector allowed express C3/C4 permission at 55 Bradford Crescent on 10th September 2026, but dismissed a similar application at No. 119 on 16th September 2026.

At No. 55, the new permission provides the basis for later qualifying changes under Class V. No separate, older flexible-use permission was needed. Obtaining one was the purpose of the application and appeal.

At No. 119, updated student-accommodation evidence and cumulative harm meant the HMO element failed on its planning merits. Retaining C3 as an alternative did not remove that harm. Both applications needed express permission because the ordinary C3-to-C4 route had been withdrawn by Article 4.

Class V therefore helps explain what can happen after an appropriate permission is granted. It does not decide whether the application should succeed in the first place.

 

The ten years run forwards, not backwards

 

Class V cannot authorise a change carried out more than ten years after the express permission was granted. The clock starts with the grant, not the first tenant, first occupation or first switch.

It is not a ten-year look-back for old permitted-development rights. It does not revive a C3-to-C4 right withdrawn by Article 4, and there is no requirement to wait ten years.

For example, a flexible permission granted in September 2026 could support qualifying changes in 2030 and 2033. A change in 2037 could not rely on Class V through that permission. Each switch does not restart the clock.

The Class V period is separate from a condition requiring development to begin within three years. The commencement conditions and other requirements of the express permission still need to be met.

 

What happens when the ten years end?

 

The Class V time limit does not, by itself, require an existing lawful use to stop or the property to revert to its former use. It restricts further changes relying on Class V through that permission.

For a later change, check the exact wording of the express permission and whether another permitted-development right or a new permission provides a lawful basis. Do not assume a permission labelled flexible guarantees unlimited switching for ever.

 

Class V is different from Class L

 

Class L itself grants specified changes between C3 and C4, subject to its limitations and any relevant withdrawal of those rights. Class V instead depends on an express planning permission specifically authorising the alternative uses.

That difference can matter in an Article 4 area. An owner with only a C4 permission should not assume that changing the property back to C3 guarantees a later return to C4 under Class L.

A properly drafted C3/C4 permission can provide the basis for Class V flexibility. The actual Article 4 Direction and the permission’s conditions must still be checked: Class V is not immune from a direction or restriction which applies to it.

Nor is Class V limited to HMOs. It can apply to other uses of buildings or land where the same express permission specifically authorised the alternatives and its restrictions are met.

 

What restrictions apply to Class V?

 

In addition to the need for the relevant express permission, Class V excludes:

• Permissions based on applications made before 5th December 1988
• Changes carried out more than ten years after the grant of permission
• A change of a building to use as a betting office or payday loan shop
• A change which would breach a condition, limitation or specification in that permission relating to the use

The general provisions of the GPDO remain relevant. Article 3 prevents reliance on permitted development contrary to relevant conditions and where the relevant existing building operations or use are unlawful.

Class V is a change-of-use right. It does not itself authorise an extension, a new building or every physical alteration needed for the proposed use. Those works need their own planning basis. At 55 Bradford Crescent, the extension was included in the full permission.

 

Do I have to notify the council before each change?

 

Class V itself contains no prior-approval application or notification requirement. Paragraph W, which follows it in Part 3, provides procedures where a permitted-development class requires prior approval. It does not impose that requirement on Class V.

Paragraph 41 of appeal 6006352 at 55 Bradford Crescent refers to notification requirements under separate statutory provisions, but does not identify the provision. That sentence should not be turned into an invented Class V notice form or deadline.

Any separate obligation must be considered on its own terms. This includes the express permission’s conditions and applicable HMO licensing, Council Tax or Building Regulations requirements. Those regimes are not a Class V notification procedure.

Keep the permission, approved plans, condition approvals and evidence of the dates of changes together. Where certainty matters, consider a certificate of lawfulness of proposed use or development. This is not a mandatory stage of Class V.

 

What should the application ask for?

 

The proposal should make clear that permission is sought for alternative uses, rather than simply one change from the existing use to a new one. The description, plans and proposed conditions need to work together.

For example, a request for flexible C3 dwellinghouse or C4 HMO use asks the authority to consider both alternatives. This differs from asking only for a change from C3 to C4, or for a mixed use in which different activities operate together.
