Peterborough HMO Planning Permission and Article 4 Direction
Planning Permission and Licensing Are Separate Systems
A common mistake among Peterborough landlords is assuming that holding an HMO licence means the property has planning permission to operate as an HMO. These are two completely separate legal regimes. The Housing Act 2004 governs licensing, while the Town and Country Planning Act 1990 governs planning permission. You may need both, and having one does not grant or replace the other.
In planning terms, residential properties fall into use classes. A standard family home is Class C3. A small HMO with three to six unrelated occupants is Class C4. A large HMO with seven or more occupants is classified as Sui Generis — outside any defined use class entirely.
The National Default: Permitted Development
Under the Town and Country Planning (General Permitted Development) (England) Order 2015, converting a property from Class C3 to Class C4 is normally Permitted Development across England. That means you do not need to apply for planning permission to house three to six unrelated people in what was previously a family dwelling — the national rules allow it automatically.
However, local councils can remove this permitted development right by issuing an Article 4 Direction, which forces landlords to apply for full planning permission before converting a home into a small HMO.
Peterborough's Article 4 Direction: Expired
Between January 2024 and January 2026, Peterborough City Council operated a trial Article 4 Direction covering four specific areas: Fletton, Woodston, Hampton, and Park. During that period, landlords in those areas needed full planning permission to convert a C3 dwelling into a C4 HMO.
As of 2026, that trial direction has expired and is no longer in force. This means national Permitted Development rights apply across Peterborough — converting a family home into a small HMO (three to six occupants) does not require a planning application unless property-specific conditions or building alterations trigger planning controls.
The council is evaluating evidence regarding possible reinstatement. Check the current position with the council before changing a property's use.

When You Still Need Full Planning Permission
Even without an active Article 4 Direction, full planning permission is mandatory whenever you are converting a property to house seven or more unrelated occupants. The move from C3 or C4 to Sui Generis is never covered by Permitted Development, regardless of where the property sits in Peterborough.
You may also need planning permission if the physical conversion involves external alterations — adding fire escapes, new windows, or changing the building's appearance — since those alterations can trigger planning controls independently of the use class change.
Licensing Still Applies
Whether or not you need planning permission, you almost certainly need a property licence. Three to four occupants from two or more households sharing facilities triggers the Additional HMO Licensing scheme (city-wide, £1,100 total fee). Five or more occupants triggers Mandatory HMO Licensing (also city-wide, £1,100). Single-family lets in a designated part of one of the ten wards need a Selective Licence (£908); check the exact address with the council.
Our Peterborough Landlord Licensing Guide walks through every scheme — which licence your property needs, the Home Safe portal application, documents required, and the fee structure — so you can handle the licensing side while sorting out the planning position separately.
Frequently Asked Questions
Does an HMO licence give me planning permission?
No. An HMO licence under the Housing Act 2004 and planning permission under the Town and Country Planning Act 1990 are separate legal requirements. You may need both, and holding one does not satisfy the other.
Is the Peterborough Article 4 Direction still in force?
No. The trial Article 4 Direction covering Fletton, Woodston, Hampton, and Park expired in January 2026. As of November 2026, national Permitted Development rights apply — you can convert a C3 dwelling to a C4 small HMO without a planning application unless property-specific conditions or other planning controls apply.
Do I need planning permission for a large HMO in Peterborough?
Yes. Any property housing seven or more unrelated occupants is classified as Sui Generis, and the change of use from C3 or C4 to Sui Generis always requires full planning permission regardless of the Article 4 position.
