Planning Permission Refused in London: Your Options and How to Appeal

Receiving a planning refusal is discouraging — but it is rarely the end of the story. Many of London's most successful residential projects started with a refused application. Understanding your options and how to respond makes all the difference.

Step 1: Read the Refusal Notice Carefully

The decision notice contains the reasons for refusal. These are the planning officer's stated grounds. Read them carefully and distinguish:

• Policy-based refusals: The proposal conflicts with a specific policy in the Local Plan or the London Plan. These are more fundamental and harder to overcome without design changes.
• Impact-based refusals: The specific design proposal is considered to have unacceptable impacts (on character, on neighbours, on heritage). These can often be addressed with a revised design.
• Procedural or information-based refusals: The application was incomplete or lacked required supporting information. Resubmission with complete information resolves these.

Option 1: Revised Application (Resubmission)

The simplest route is to address the grounds of refusal in a revised design and resubmit. If your original application was a householder application, the first resubmission within 12 months of a refusal is typically free (no additional planning fee).

Before resubmitting:

• Discuss the proposed design changes informally with the planning officer who determined the application. This is not always possible but can clarify whether the revised approach would be acceptable.
• Engage an architect who understands the local planning authority's expectations for the area.
• Commission any supporting information identified as missing (daylight assessment, heritage statement, arboricultural survey).

Success rate: Revised applications that genuinely address the grounds of refusal have a good success rate. Applications that resubmit a nearly identical scheme with only token changes are usually refused again.

Option 2: Appeal to the Planning Inspectorate

If you believe the refusal was wrong in planning law — either because the grounds cited are not genuine material planning considerations, or because the balance of considerations should have favoured approval — you can appeal.

Who decides: The Planning Inspectorate (an independent government body). The appeal is determined by a Planning Inspector, not the original planning authority.

Types of appeal procedure for householder applications:

• Written representations (most common for householder applications): Both parties submit written statements; the Inspector visits the site and issues a written decision. No hearing.
• Hearing: A more formal process where the Inspector chairs a discussion between the parties.
• Inquiry: A formal quasi-judicial process with legal representation. Not typical for householder applications.

Timescales: Householder appeals determined by written representations typically take 20–26 weeks from submission to decision (as of 2026). Planning Inspectorate wait times have extended significantly in recent years.

Costs: The appeal itself is free. However, if you instruct an architect or planning consultant to prepare and submit your appeal (strongly recommended for all but the simplest cases), their fees will apply. Typical planning consultant fee for a householder written representations appeal: £1,500–£4,000.

Success rate: Nationally, approximately 30–35% of householder planning appeals succeed. Success rates vary by authority and reason for refusal — appeals against refusals on design grounds tend to have lower success rates than appeals against refusals based on disputed impact assessments.

Costs awards: In exceptional cases, the Inspectorate can award costs against a party who has behaved unreasonably. If the council refused your application for unsustainable reasons, a costs award in your favour is possible — but this is the exception, not the rule.

Option 3: Pre-Application Consultation

Before committing to either route, consider requesting a formal or informal pre-application consultation with the planning authority. Many London boroughs offer a paid pre-application advice service where a planning officer will review a revised proposal and give informal feedback on its acceptability.

This service (typically £200–£600 for a householder application) can:

• Identify whether a revised proposal would likely be approved before the cost of a full application
• Give a steer on specific design changes that would make the proposal acceptable
• Confirm whether the refusal grounds reflect a fundamental policy conflict or a specific design issue

Pre-application advice is not binding — the planning authority can refuse a scheme they said was likely acceptable in pre-application discussions — but it significantly reduces the risk of a second refusal.

Option 4: Lawful Development Certificate (for Permitted Development)

If your refused proposal could be redesigned to fall within Permitted Development limits, you may be able to achieve a similar outcome without planning permission at all. Consider whether a scaled-back version of your proposal — different depth, height, or position — qualifies as PD and achieves most of your objectives.

An LDC (approximately £206 fee) confirms that the PD proposal is lawful.

When to Accept the Refusal

Some refusals reflect a genuine and consistent policy position that will not be overturned by appeal or revision. Signs that the refusal may be insurmountable:

• The grounds cite a specific, clear policy that your proposal unambiguously conflicts with
• The same type of proposal has been refused consistently in your area
• Pre-application advice (if sought) confirms the authority will refuse similar schemes
• An experienced planning consultant advises against appeal

In these cases, redesigning the project within what is acceptable — perhaps a smaller extension, a different dormer type, or a revised layout — produces a better outcome than pursuing a difficult appeal.
