Do I need Planning Permission?

If you are intending to construct a new building, alter the appearance of an existing building or change the use of a building you are likely to require planning permission the Planning Portal provides guidance on use classes (external link)

Some minor alterations and extensions, particularly to houses, are classed as ‘permitted development’ and do not require planning permission.

Common projects which may require Planning Permission

The Planning Portal website (external link) offers general advice on householder extensions and other common projects on when planning permission is required. Additionally, the following alterations and proposals require planning permission:

  • If you live in a flat or maisonette, you are likely to need planning permission for many alterations, including changes to windows and doors
  • Change of use: if you are planning to change the use of a building you may require planning permission
  • If you live in a Conservation area, you may be subject to additional restrictions known as Article 4 Directions. To find out if you live in a conservation area, please consult our Conservation areas page
  • If you intend to carry out works to protected trees (under a tree preservation order), or to trees in a conservation area, you will need the council’s permission. Further guidance can be found on the Tree Preservation Orders pages
  • If you intend to alter Listed buildings internally or externally, you will probably require Listed Building Consent
  • If you intend to display advertisement and signage you will probably require Advertisement Consent
  • If you are carrying out new building work, you will probably have to comply with Building Regulations - please see our Building Control pages for further guidance

Permitted Developments

Legislation categorises buildings into separate ‘use classes’, depending on the purpose that the building is used for. Certain changes from one kind of use class to another are subject to permitted development rights and do not require planning permission. Additionally, a number of minor alterations and extensions made to residential houses can be carried out without planning permission.

Common projects with permitted development rights are outlined in detail on the planning portal. The relevant forms for permitted development requiring prior approval can be found on our Forms and Fees page.

Certificate of Lawfulness

Before carrying out any permitted development works we recommend that you apply for a lawful development certificate (LDC). This is not the same as planning permission but is proof that your building work is lawful. Even if you are sure your project is permitted development it provides formal confirmation which provides peace of mind and if you should later want to sell your property, an LDC may be helpful to answer queries raised by potential buyers or their legal representatives. You can apply using the Planning Portal's secure online application service (external link). The application requires a site location plan, accurate scale plans of the existing and proposed property and an application fee. 

You can also download the application form from our Forms and Fees page

The Council offers a Fast Track service for the assessment and issuing of Lawful Development Certificates.  The fee for this additional service is £621 including VAT.  On submission, your application will be allocated to a dedicated case officer who will make a decision within 5 working days (subject to all relevant information having been provided on submission).  

To request this Fast Track Service please email preapp@haringey.gov.uk
