What Is a Householder Planning Application?

A householder planning application is for works to an existing house - extensions, loft conversions, outbuildings, and other alterations.

What is a householder application?

A householder planning application is a specific type of planning application used for works to an existing single dwelling house. It covers alterations, extensions, and improvements to a house and its grounds - but not the creation of a new separate home.

This is the most common type of planning application in England, accounting for roughly 40% of all applications submitted each year.

What does it cover?

Householder applications are used for:

• Extensions - rear, side, two-storey, wraparound
• Loft conversions with dormers or raised ridgelines
• Detached outbuildings (garages, garden rooms, annexes that aren't separate dwellings)
• Changes to the roof (adding dormers, changing materials)
• Porches larger than permitted development allows
• New or altered vehicular access
• Walls, fences, and gates above PD limits

When do you NOT use a householder application?

You'd need a different type of application if you're:

• Building a new, separate dwelling (use full planning application)
• Subdividing a house into flats (change of use)
• Working on a flat or maisonette (full application)
• The work falls within permitted development rights (no application needed)

How to apply

1. Check if you need permission - some works are permitted development
2. Prepare drawings - you'll need existing and proposed plans, elevations, and a site plan
3. Submit online - via the Planning Portal or your council's website
4. Pay the fee - currently £258 in England (2024)
5. Wait for a decision - the target is 8 weeks

What does the council consider?

The planning officer will assess your proposal against:

• Impact on neighbours (overlooking, overshadowing, loss of light)
• Scale and design relative to the existing house and street scene
• Materials and appearance
• Impact on parking and highway safety
• Impact on trees, wildlife, or heritage assets
• Compliance with local plan policies and supplementary planning guidance

Key facts

• Householder applications are for works to a single existing house
• They're the most common type of planning application in England
• The fee is £258 (England, 2024)
• Councils aim to decide within 8 weeks
• Always check permitted development first - you may not need to apply at all
