Bolton HMO Article 4: what landlords need to know

What an Article 4 direction actually does

Permitted development rights allow certain changes to happen without a planning application. One of them has long been the change from a dwellinghouse — use class C3 — to a small house in multiple occupation for up to six residents, use class C4. Where that right applies, a landlord can convert without asking anyone.

An Article 4 direction is the mechanism a local planning authority uses to withdraw a permitted development right across a defined area. Where one is in force, the conversion is not prohibited. It stops being automatic. It becomes a planning application, which the authority then determines on its merits against its own policies.

That distinction matters commercially, and Bolton Council makes it explicitly: an Article 4 direction does not mean a planning application for a small HMO would be automatically refused.

Bolton’s position

Bolton Council introduced a borough-wide immediate Article 4 direction on Friday 13 June 2025, removing the permitted development right to convert a dwellinghouse (class C3) into a house in multiple occupation (class C4) for up to six residents. The direction was confirmed in November 2025.

Three things follow from how that was done.

• It is borough-wide. There is no part of Bolton where the old permitted development route still applies, and no ward map to check.
• It was made as an immediate direction. It took effect on the day it was introduced rather than after the usual period of notice, so 13 June 2025 is the date that matters when establishing when an existing use began.
• It covers the whole of the C4 class. The previous position, under which a conversion for up to six residents needed no application at all, has gone.

Planning permission and an HMO licence are not the same thing

This is the single most common confusion we meet at viewings, and it is an expensive one.

Planning permission concerns the lawful use of a building. Licensing concerns the standard to which it is run, the condition it is kept in and the fitness of the person running it. They sit with different parts of the council, under different legislation, and are decided on different tests.

Holding one does not imply the other. A property can hold a current HMO licence and still have no planning permission for its use. It can have permission and be unlicensed. Neither passes automatically to a buyer on completion, and a previous owner having operated the building a certain way for years is evidence of something, but it is not consent. The licensing side is covered in the Bolton HMO licensing guide.

What to establish before you convert, buy or hand over a building

• What the building’s lawful planning use is now, and what evidence supports that.
• If it is already in shared occupation, when that use began — and specifically whether it began before 13 June 2025.
• Whether planning permission has been granted for the current or intended use, and on what conditions.
• What the council’s planning policy says about HMO concentration in that location. The direction makes that policy the deciding factor rather than a background consideration.
• What happens to your numbers if permission is refused, or granted with conditions you had not priced — and whether you are committed to a purchase or a spend before you know the answer.

Why an operator asks all of this

We decline buildings where the lawful position on planning and licensing cannot be established from the outset. That is not caution for its own sake. An operator who takes on a building with an unresolved planning position takes on the enforcement risk attached to it, and so, in practice, does the owner who handed it over. Establishing the position first is materially cheaper than establishing it afterwards.

It is also why the question comes up at the viewing rather than at the contract stage. It is the fastest way to find out whether there is a deal here at all.
