Permitted development rights

You may be able to make minor changes to your property without needing to apply for formal planning permission under a general planning permission granted by Parliament known as ‘permitted development rights’.

These rights are more restricted for properties in conservation areas. There are also different requirements for listed buildings.

For more information, please see the Planning Portal

In 2013, significant amendments were made to permitted development rights affecting houses, schools, offices, shops and other commercial and industrial buildings. You may need to formally notify us or apply for prior approval before the development takes place in order to benefit from these new permitted development rights. Access the forms

Removal of permitted development rights on office to residential change of use

We have made an Article 4 Direction to remove permitted development rights for changes of use from B1(a) (offices) to C3 (dwelling houses) in Westminster’s Central Activities Zone. 

Over 300,000 square metres of office space have been redeveloped or converted to residential properties in Westminster’s Central Activities Zone since 2010. This has led to an under-supply of offices, pushing up rents and affecting business activity and competitiveness.

In 2013 the government changed planning law to allow changes from office to residential use without the need for a planning application. This was subject to an exemption for the Central Activities Zone and was intended to lapse after 3 years. The government has decided to make this permitted development right permanent and to lift the exemption, meaning that to continue the current position the council will have to use its powers under article 4 of the Town and Country Planning (General Permitted Development) (England) Order 2015 to require full a planning application for this kind of development.

This Article 4 Direction is necessary so that the council can use its planning powers to protect mixed uses in the Central Activities Zone, to prevent a continuous loss of office floorspace in the area and to help maintain the zone’s competitiveness, striking a balance between both office and residential uses. Consultation on this Article 4 Direction run from 20 February until 6 April 2018.

It is proposed that the Article 4 Direction will come into force on 1 May 2019. 

Further background is given in the cabinet member report (PDF, 550KB) authorising the making of the direction.

Change of use from shops to financial and professional services

We have made an Article 4 Direction to remove permitted development rights for changes of use from A1 (shops) to A2 (financial and professional services) in the Core Central Activities Zone and the designated shopping centres throughout the city. While financial services like banks provide a valuable local service, this is necessary so that the council can use its planning powers to protect variety and prevent particular industries from dominating retail space in shopping centres. The consultation period on this ended on 14 December 2015. The Article 4 Direction was confirmed on 12 December 2016 and comes into force on 1 January 2017.

Article 4 Directions

An Article 4 Direction is a direction under Article 4 of the General Permitted Development Order which enables the local planning authority to withdraw specified permitted development rights across a defined area. This would bring these types of development within the control of the planning process.
