Do I need planning permission?

Planning permission may be required for a wide variety of development, whether it be new building works or changes in the use of land or buildings. However, there are many kinds of alterations and additions to buildings and changes in the use of land or buildings for which you do not need to apply for planning permission.

At present the Planning Department are not offering a service of permitted development or pre application enquiries while the service continues to prioritise planning applications whilst we’re in a position of filling numerous planning officer vacancies.

We appreciate that the permitted development enquiry service has always been valued, providing customers with guidance as to whether their development would likely constitute planning permission. It’s acknowledged that it can be hard to navigate the publicly available information for customers to make their own judgement as to whether planning consent would be required.  

Permitted Development Request

Free advice is available through our self-assessment forms to help you determine whether or not you will need to apply for Planning Permission. The self-assessment forms cover most types of development on your home.

Please follow the steps carefully and answer each question accurately.  If you answer "YES" to any questions or do not comply with any conditions then you will need to submit a planning application. This can be submitted on-line through the Planning Portal. Alternatively, you can visit the Planning Portal website which provides advice in a different way.

Important Disclaimer

The self assessment forms do not provide you with a formal decision and will not confirm whether planning permission would be granted.  If you require a formal decision as to whether a use or development, proposed or existing is lawful then you should submit an application for a certificate of Lawful Development. Further guidance is available Lawful Development Certificates - A User's guide  from GOV.UK and an application can be submitted on-line through the Planning Portal

Building Regulations 

Please remember that even if you do not require planning permission you may still require a separate approval under the Building Regulations. For further information please visit our Building Control website  or contact us by phone on 01302 734848.

In some cases where you do not need to apply for planning permission you will still need to apply for approval to carry out works to protected trees; or some other form of statutory consent. It is the applicant's duty to ensure that all necessary consents are in place before carrying out a development.

Larger home extension scheme (neighbourhood consultation scheme)

The scheme relates to planning and is a method of prior approval, if you wish to build a large extension you must notify the local authority, who will then consult the adjoining neighbours to advise them of your planned development. 

If your neighbours raise any concerns or objections, the local authority will decide if their objections reveal any impact on the amenity of the neighbouring properties and whether your plans can go ahead. 

This scheme only applies to larger single-storey rear extensions. This means that extensions of over four and up to eight metres for detached houses and over three and up to six metres for all other houses, must go through this process. 

Work carried out on trees

Any pruning or felling of a Tree covered by a Tree Preservation Order will require consent. Any works to Trees in a Conservation Area require six weeks notice in writing. For the planning application forms please refer to the

Demolition of a building

Permission is not always needed to demolish a building. However, there are situations where permission is required, so you are advised to check with a Planning Officer before demolition is carried out.

Planning permission may also be required to re-build a demolished or partly demolished building and to demolish buildings and structures within a Conservation Area.  

Change of use

The use of a building or an area of land will fall into a category within the Town and Country Planning (Use Classes) Order 1987. Changing the use from one category to another may require planning permission. You should check with a Planning Officer before changing the use.

The uses classes cover such as Shops, Food and Drink, Financial and Professional Services, Business, General Industry, Storage and Distribution, Dwelling Houses, Residential Institutions, Hotels, Non-residential Institutions, Assembly and Leisure.

Some uses fall into a 'Special Category' called Sui Generis. This category includes any uses not falling into any of the above mentioned categories. Any use changing to a use within this category will require planning permission.

In general, if the proposed use is within the same 'use class' as the existing use, then planning permission is not required to change. However, uses within certain use classes are able to change to other use classes without requiring planning permission.

To find out more about the specific uses within the Use Classes Order visit:

Outdoor advertisements

Express consent is required for the majority of outdoor advertisements, including shop signs and poster boards. For example, all illuminated adverts require consent. There are, however, certain exceptions. You should contact the Planning Department to find out if you will require consent for your proposed adverts.
