Householder full application

The Householder Application for Works or Extension to a Dwelling form should be used for proposals to change or enlarge a single house, including works within the curtilage of a house. Proposals to alter or enlarge more than one house will need a full planning application.

The decision-making period allowed for this type of application is 8 weeks from the date the application is validated.

Minor works do not always need planning permission, please refer to the Planning Portal Guide Do you need permission? before you apply.

Supporting documents that may be needed to go with your application:

Current national fees can be found on the Planning Portal. Guidance: GOV.UK: Fees for planning applications

To support you please use the Planning Portal fee calculator.

Use an up-to-date Ordnance Survey-based location plan at an appropriate scale, usually 1:1250 or 1:2500. In the case of large sites other scales may be appropriate.

The site boundary must be edged clearly with a red line. It should include all land necessary to carry out the proposed development - for example, land needed for access to the site from a public highway, visibility displays, landscape, car parking and open areas around the building. A blue line should be drawn around any other land owned by the applicant, close to or adjoining the application site.

When is it required?

One may be required if:

  • the proposed development involves the demolition of any existing structures
  • there are trees on site that may be affected by the proposed development.

What is needed

Existing site layout plans for a recognised scale (1:100, 1:200 or 1:500 as appropriate) should show:

Roof lights should be indicated on floor plan.

Is it required?

  • for major development (defined as development of 10 or more dwellings (or 0.5 hectares for residential development where the number of dwellings is unknown) for the creation of more than a 1,000 square metres of floor space and where the site is greater than 1 hectare).
  • for development in a designated area (World Heritage Site or conservation area) where the proposed development consists of either one or more dwellings or a building or buildings with floor space of 100 square metres or more.
  • for applications involving listed building consent.

What is required?

A design and access statement should:

  • state what, if any, consultation has been undertaken on issues relating to access to the development and what account has been taken of the outcome of any such consultation
  • explain how specific issues which might affect access to the development have been addressed.

Statements accompanying applications for Listed Building Consent should, in addition to the above, show how they have taken account of:

  • the special architectural or historic importance of the building
  • the particular physical features of the building that justify its designation as a listed building
  • the building's setting.

When is it required?

A site specific Flood Risk Assessment (FRA) is required if the site is:

  • In flood zone 2 or 3 including minor development and change of use
  • More than 1 hectare in flood zone 1
  • Less than 1 hectare in flood zone 1, including a change of use in development type to a more vulnerable class (for example from commercial to residential), where they could be affected by other sources of flooding such as surface water.

What is required?

If a development is proposed in an area of flood risk (either fluvial or surface water), a site specific FRA should be undertaken. This should:

  • Include evidence that the Sequential Test and where necessary the Exception Test have been applied in the selection of the site for the development type. 
  • Take into account different types of flooding: for example, fluvial, surface water and groundwater.
  • Consider the risk of flooding arising from the proposed development as well as to the development site.
  • Take into account the effect of climate change.

When is it required?

Development affecting a heritage asset. Heritage assets are buildings, monuments, sites, places, areas or landscapes which are significant because of their historic interest.

Designated heritage assets include:

  • World Heritage Site
  • Scheduled Monument
  • Listed Building
  • Registered Park and Garden
  • Conservation Area

For new development, consideration should be given to the potential of archaeological assets.

What is required?

The level of information or investigation required to support a proposal that could impact on a heritage asset needs to be proportionate to the significance of the heritage asset and the potential impact of the works proposed. Pre-application meetings are strongly recommended.

As a minimum, statements will be required to identify heritage assets and demonstrate how proposals have preserved or enhanced their significance.

When is it required?

Noise / Vibration Generation

Where a proposed new development would generate noise or vibration including delivery and servicing and vehicle movements / traffic changes on local roads which may have a negative impact on existing or planned uses (in particular noise sensitive uses such as residential, hospitals, nursing homes, schools etc.).

Applications which involve the installation of mechanical and electrical building services plant / equipment such as flues, air handling units / air conditioning, extraction, air source heat pumps, combustion appliances etc.

New Noise Sensitive Premises

Proposals for residential and other noise sensitive development close to existing sources of noise such as transport (road, rail and air) and industrial, commercial or business premises.

Where the operation of an existing / established business or community facility generating noise could have an unacceptable significant adverse effect on proposed new development (including changes of use) in its vicinity such as the introduction of new noise sensitive premises into an area e.g. residential ('agent of change principle').

What is required?

Where necessary an acoustic (noise and vibration) assessment will be undertaken by a suitably qualified and competent acoustician / person, in accordance with the latest industry and/or Government best practice guidance and relevant British Standards publications.

The assessment shall detail the existing noise environment, the potential noise sources / activities associated with the development and /or the noise sources likely to affect any noise sensitive development. Details of the number of deliveries and the times when deliveries and servicing takes place.

The duration, scope / remit and content of the assessment or supporting information should be discussed and agreed in advance with the local planning authority before it is commissioned, but in any event must comply with relevant and up-to-date UK guidance and standards.
