How to Apply for Householder Planning Permission — Step by Step
Most people encounter the planning system only when they want to extend or alter their home. The process can feel opaque, particularly when councils have their own local requirements layered on top of the national framework. This post takes you through a householder planning application from start to finish — what you need, what the council looks for, and what happens after a decision is made.
When Do You Need Householder Planning Permission?
The first question to resolve is whether you need permission at all. A significant range of works to an existing house — rear extensions below certain thresholds, loft conversions with rooflights, outbuildings within limits — are permitted development under the Town and Country Planning (General Permitted Development) (England) Order 2015 (GPDO). Permitted development rights can be restricted by Article 4 Directions, by conditions on previous consents, or by the nature of the property (flats and listed buildings have no householder PD rights).
If your proposed works are outside PD limits, are in an Article 4 area, or if you want a formal confirmation that you do not need permission, you will need either a Lawful Development Certificate (LDC) or a householder planning application.
A householder planning application is the correct route when: - The works exceed PD limits or are in a restricted area - The works involve a material change of use alongside the physical alterations - You are working in a conservation area and the proposed works require CA consent alongside planning
The householder application covers alterations and extensions to an existing dwelling house. It is a simplified form of the full planning application and is available only for proposals affecting a single existing dwelling. If you are splitting a property into two dwellings, creating a new dwelling, or changing the use, you need a full planning application instead.
The Application Portal: Planning Portal
All householder applications in England are submitted through the Planning Portal at planningportal.co.uk. The portal takes you through a structured online form, allows you to upload documents, and routes your submission to the correct LPA. You can also pay the application fee through the portal (currently £258 for most householder applications as of the 2025 fee schedule, though you should confirm the current fee at the time of submission).
Your architect or designer will typically manage the application on your behalf, but you as the applicant are the responsible party. Make sure you understand what is being submitted in your name.
What Documents You Need
Most householder applications require the following:
Site location plan (scale 1:1250). This identifies the application site in context. The application site must be clearly edged in red, and any other land in the applicant's ownership edged in blue. Ordnance Survey-based plans are required. Do not use Google Maps screenshots — they do not meet the required standard.
Block plan / site plan (scale 1:500). This shows the site and its immediate context in more detail — the footprint of the existing building, neighbouring buildings, boundaries, access, and the location of the proposed works.
Existing and proposed floor plans. Plans showing the layout of the building as it currently is and as it would be after the works are complete. Drawn to scale (usually 1:50 or 1:100) and showing dimensions.
Existing and proposed elevations. Drawings showing the external appearance of the building from each relevant direction. Must show materials and finishes where relevant.
Existing and proposed sections — required where there are significant changes in level or where the interior arrangement is relevant to understanding the proposal.
Design and Access Statement. This is required for applications in a conservation area, for listed building consent applications, or for major development. For a straightforward householder application in a non-designated area, it is usually not required — but it is sometimes worth including a brief statement explaining design choices, particularly if the proposal is at the edge of what is acceptable.
Some councils also ask for a Tree Survey or Arboricultural Impact Assessment where trees are present, a flood risk assessment where the site is in Flood Zone 2 or 3, or a heritage statement where the property is adjacent to a listed building.
Validation: What the Council Checks Before Registering Your Application
Once submitted, the council's planning department validates the application — checking that all required documents have been provided and that the fee has been paid. If anything is missing, they will return it as invalid. Under the National Planning Policy Guidance (NPPG), the council should tell you within 15 working days if the application is invalid. If they do not, the application is treated as valid from the date it was received.
Validation does not mean approval. It simply means the council is satisfied they have enough to begin the assessment.
The Statutory Determination Period
The council has 8 weeks from the date of validation to determine a householder application. This is set out in the Town and Country Planning (Development Management Procedure) (England) Order 2015 (DMPO 2015), Schedule 1. For major applications the period is 13 weeks; householder applications fall within the 8-week bracket.
If the council has not issued a decision by week 8, you can appeal to the Planning Inspectorate on grounds of non-determination — but in practice, you should first contact the case officer and ask for an update. Most councils prefer to resolve applications rather than face appeals. The case officer can also ask for an extension of time if they need it, which you can agree to or decline.
If you reach week 10 or 11 with no decision and no communication, exercise your right of appeal. The Planning Inspectorate charges no fee for householder appeals, and the mere act of lodging an appeal often prompts a council to issue a decision quickly.
Pre-Application Advice: Worth It or Not?
Most councils offer a pre-application advice service, typically costing between £75 and £300 or more depending on the scale and location. For a genuinely borderline proposal — one that pushes design standards, is in a sensitive location, or involves an unusual approach — pre-application advice is often worth the time and money. It gives you an officer's informal view before you incur drawing fees and submission costs.
For a straightforward rear extension in a non-designated area that is clearly within acceptable parameters, pre-application advice is usually unnecessary. Experienced designers know what is likely to be acceptable and can advise you accordingly.
Neighbour Objections and Material Considerations
The council notifies neighbours of your application and invites comments for a statutory period (usually 21 days). Objections from neighbours are not a veto on your application. Planning is not a popularity contest; the case officer must weigh material planning considerations — impact on neighbouring amenity, design quality, highway matters, ecological impact — and measure the proposal against development plan policies.
Objections that amount to personal dislike, loss of view (not the same as loss of daylight), or general opposition to development carry very little weight. Relevant, policy-grounded objections about overlooking, overshadowing, or loss of light may carry more. A strong application with a well-argued Design and Access Statement can often rebut neighbour concerns clearly.
After Approval: Conditions and Commencement
Planning permissions are almost always granted subject to conditions. Standard conditions include a three-year commencement condition (you must start work within three years of the date of permission) and pre-commencement conditions (things you must do before any work begins — usually approvals of materials, landscaping, drainage, or details of specific elements).
Read your conditions carefully. Breaching a pre-commencement condition means any work you do before discharging it is potentially in breach of planning control. Conditions must be formally discharged through an application to the council (typically low-cost, around £34 per application).
Once conditions are discharged and work starts, the permission is implemented. If you want formal proof of implementation — useful if you later sell the property or need to demonstrate that the consent is live — you can apply for a Lawful Development Certificate for commenced development.
At RCB, we review planning consents and their conditions as part of our pre-construction process. We want to understand exactly what has been approved, what the conditions require, and what this means for our scope of works and programme before we price a job. Understanding your approval before we start is how we protect both you and ourselves.
