Planning policy

Article 4 Directions

Article 4 Directions are issued to require planning permission for certain types of development where permission is not normally required.

Certain works that would normally require planning permission are permitted by the General Permitted Development Order (GPDO) 2015. 

The GPDO enables councils to issue an Article 4 Direction, which restricts the scope of permitted development rights either in relation to a particular area or site, or a particular type of development anywhere in the authority's area. Article 4 Directions are issued where evidence suggests that undertaking certain types of development (where planning permission is not normally required) would harm local amenities or the proper planning of an area. 

The council introduces each Article 4 Direction under the The Town and Country Planning GPDO 1995 . Where an Article 4 Direction is in effect, a planning application may be required for development that would otherwise have been permitted development. 

Please note: An Article 4 Direction does not prevent the development but instead requires planning permission to be obtained first from the council. This does not imply that the council will either approve or refuse the planning applications.


Changes of use from commercial, business and service uses to dwellinghouses 

On 14 July 2022, the council confirmed a non-immediate Article 4 Direction to remove permitted development rights to change from commercial, business and service uses to dwellinghouses.  This is the permitted development right covered by Class MA of Part 3 of Schedule 2 of the Town and Country Planning (General Permitted Development) Order.  The Article 4 direction will come into force on 24 September 2022. 

The Article 4 Direction in relation to Class MA applies in the following areas of the borough:  

  • office and hotel growth location
  • locally significant employment locations
  • Hayes opportunity area
  • strategic industrial locations
  • locally significant industrial sites
  • primary and secondary shopping areas in metropolitan town centres
  • primary and secondary shopping areas in district town centre
  • primary and secondary shopping areas in minor town centres
  • local centres
  • local parades.

This type of development in these areas will require full planning permission. This is to ensure we can control and protect important areas of economic activity within the borough, including industrial areas and high streets. Where new residential development is proposed, it will continue to be subject to consideration against the policies in the Local Plan.

Houses of Multiple Occupation (HMOs)

From March 2013, Hillingdon Council has made changes to the planning rules for houses of multiple occupation.

What's changed?

It's necessary to obtain planning permission to convert a family dwelling (Use Class C3) to a HMO with between 3 and 6 unrelated people sharing (Use Class C4) throughout the wards of Brunel and Uxbridge South.

Please note: Planning permission is already required for properties shared by 7 or more unrelated people. 

Why the change?

The council is concerned about the effects of high concentrations of student housing in certain areas.

What properties are covered by the Article 4 Direction?

The Direction relates to development changing the use of a building to a Class C4 (houses in multiple occupation) from a use falling within Class C3 (dwelling houses). It removes permitted development rights for this type of development.


Protection of strategic employment land

What's changed?

The Direction relates to development comprising the change of use of employment buildings to a residential use.

The Article 4(1) Direction removes permitted development rights B1(a) and B1(c) to C3 (Class O of the 2015 GPDO and Class PA of the 2016 GPDO, respectively) in specific parts of the borough to protect strategic employment land.

Planning permission is required for change of use to residential from 22 November 2017 in the strategic locations identified under the Article 4(1) Direction below.
