Reasons why planning applications may become invalid

Validation

Upon submission, and before an application is passed to a planning officer for consideration/determination, it undergoes a stage called 'validation'. This is when the documents supplied are assessed to ensure they are of sufficient quality for a Planning Officer to be able to use them to make the assessments required during the life of the application and ultimately a decision.

The validation process is a qualitative check of the documents submitted as part of the application. things considered are;

  • Details on the application form must match the works shown on the plans  
  • all the plans correspond to show the same proposed works and matching details (for example the floor plans will be compared to the elevation plans to ensure that the windows, doors and other features are correctly located on both plans).

If any documents submitted are not of the required standard then your application will be deemed 'invalid', placed on hold and any necessary amendments or submission of any required documents will be requested. If the documents requested are not supplied within 28 days then your application and all documents submitted in support of it will be returned to you.

Most common reasons why a planning application may become invalid:

Inadequate Elevations Plans / No Elevation Plans Supplied

Inadequate Location Plan / No Location Plan Supplied

Inadequate Block Plan / No Block Plan Supplied

Inadequate Floor Plans / No Floor Plans Supplied

No Fee / Incorrect Fee Supplied

Inadequate Elevation Plans / No Elevation Plans Supplied​

Elevation plans should be scaled to a recognisable scale that must be appropriate to illustrate the works proposed, typically scale 1:50 or 1:100. A larger scale may be appropriate if the structure involved in the application is particularly large. In such an instance a scale of 1:200 may be used.

The elevation plans should match the scale/s stated on the plans. Should the dimensions not match those of other plans (or any measurements provided on the plan itself) when measured using the scales provided, then the application will be invalidated. It is therefore essential that you ensure that elevation plans are drawn as accurately as possible along with any other accompanying plans. Please also remember that if your application involves the physical alteration of an existing structure (e.g. extension to a dwelling, installation of new shop front etc.) both existing elevations (elevation prior to works) and proposed elevations (showing the works detailed as part of the application) must be supplied.

Inadequate Location Plan / No Location Plan Supplied​

The location plan should illustrate the development site in relation to its surroundings and the site of the works. The boundaries of the property must be marked with a red line. Any areas of associated ownership must also be marked with a blue line. The plan MUST be scaled at 1:1250, or if the development site is either too large or in an isolated rural area then it may be more appropriate to use a scale of 1:2500. Location plans must show at least two named roads in relation to the property. Location plans can be purchased from external retailers either in their local outlets or online (see external links).

Inadequate Block Plan / No Block Plan Supplied

Block plans must show the site and its immediate surroundings in more detail and at a closer scale than the location plan. The block plan must show the site, associated parking provision, adjoining roads and properties. Block plans must be provided at a scale of 1:200 or 1:500 depending on the scale required to best show the proposed works to the site as described on the application form. The location of any external alterations that increase the footprint (floor area) of the property MUST be marked on the plan. This plan will be measured using the scale provided and MUST match the floor plans. Should the measurements of the floor plans not match the block plan then the application will be invalidated.

Inadequate Floor Plans / No Floor Plans Supplied

All floor plans submitted must show and be of a recognisable scale. Scales acceptable for floor plans are 1:50 and 1:100. Any measurements marked on floor plans supplied with the application will be checked to measure correctly using the scale provided. Measurements (both annotated and those taken using the scale) must also match the elevations and block plans. Remember to clearly label if they are existing or proposed plans and to put the scale on the plan. Where alterations are proposed which will result in a change to the floor plan of a property either through internal changes (e.g. as part of a change of use application) or through external alterations such as extensions, existing and proposed floor plans MUST be provided.

No Fee / Incorrect Fee Supplied

Most planning applications have an associated fee. The fee will vary depending on the type of planning application you are submitting. If a fee is not supplied the application will be invalidated and the fee will then be requested. If you are submitting an application via the planning portal and paying by cheque, please send the cheque to us as soon as possible following the submission of your application. Until we receive your fee your application will not be validated. Once the fee is received the application will be made valid from that date (so long as all other criteria for other documents have also been met).
