Planning Permission in the UK: A Complete Homeowner's Guide | JG Construction

Whether you're planning a home extension, loft conversion, new build, or major renovation, understanding planning permission in the UK is one of the first and most important steps. At JG Construction, we help homeowners across Rochdale, Greater Manchester and the North West turn their ideas into reality, ensuring projects are planned correctly from the very beginning.

This guide explains what planning permission is, when you need it, how to apply, and what to expect throughout the process.

What Is Planning Permission?

Planning permission is approval from your local planning authority (LPA) allowing you to carry out certain types of building work or changes to land and property. It ensures that developments are appropriate for the surrounding area, neighbouring properties and the wider community.

Not every building project requires planning permission, but it's important to know the difference before work begins.

What Projects Usually Need Planning Permission?

You may need planning permission for:

• Large home extensions

• Two-storey extensions

• New build homes

• Significant alterations to your property's appearance

• Building on designated or protected land

• Converting land for a different use

• Commercial developments

• Some garage conversions

• Outbuildings that exceed permitted development limits

If your property is a listed building or located within a conservation area, additional permissions are often required.

What Is Permitted Development?

Many homeowners are able to carry out improvements under Permitted Development Rights, meaning planning permission isn't required.

Examples can include:

• Certain single-storey rear extensions

• Loft conversions within size limits

• Porches

• Garden buildings

• Some roof alterations

• Replacement windows and doors

However, strict rules apply regarding:

• Overall size

• Height

• Distance from boundaries

• Materials used

• Impact on neighbouring properties

Every property is different, so it's always worth checking before work starts.

How Do You Apply for Planning Permission?

The planning application process is straightforward when managed correctly.

Step 1 – Develop Your Ideas

Decide exactly what you want to achieve. Whether it's more living space, a kitchen extension or a complete renovation, having clear objectives makes the process much smoother.

Step 2 – Prepare Professional Drawings

Scaled architectural drawings are normally required, including:

• Existing floor plans

• Proposed floor plans

• Elevations

• Site location plans

• Block plans

These allow the planning officer to assess your proposal accurately.

Step 3 – Submit Your Application

Applications are submitted online through the Planning Portal or directly to your local council.

You'll usually need:

• Application forms

• Site plans

• Architectural drawings

• Design and Access Statement (where applicable)

• Supporting documents

• Application fee

Step 4 – Consultation Process

Your local authority will consult:

• Immediate neighbours

• Relevant departments

• Statutory consultees (where required)

Comments are usually accepted over a consultation period of around three weeks.

Step 5 – Planning Decision

Most standard householder applications are determined within approximately 8 weeks, although larger or more complex developments can take longer.

The council will either:

• Approve the application

• Approve with conditions

• Refuse the application

If refused, you may amend the plans or appeal the decision.

What Information Will You Need?

To give your application the best chance of success, you'll normally need:

• Accurate property measurements

• Existing site plans

• Proposed drawings

• Property ownership details

• Design information

• Access arrangements

• Drainage information (where applicable)

• Tree surveys (if required)

• Ecological surveys (for certain developments)

Some larger projects may also require structural engineering input.

Building Regulations vs Planning Permission

Many homeowners confuse these two approvals, but they serve different purposes.

Planning Permission considers how your development affects the surrounding area.

Building Regulations ensure your project is built safely and complies with current construction standards covering:

• Structural stability

• Fire safety

• Insulation

• Ventilation

• Drainage

• Electrical work

• Accessibility

Even if planning permission isn't required, Building Regulations approval often still is.

Common Reasons Applications Are Refused

Planning applications are most commonly refused because of:

• Overlooking neighbouring properties

• Loss of privacy

• Excessive size or scale

• Poor design

• Impact on highways or parking

• Flood risk

• Heritage considerations

• Conflict with local planning policies

Careful planning before submission can significantly improve your chances of approval.

Can You Build Without Planning Permission?

Starting work without the correct permissions can result in:

• Enforcement notices

• Legal action

• Expensive alterations

• Demolition orders

• Difficulties when selling your property

Always confirm whether permission is needed before construction begins.
