Application for NPPR Exemption / Compliance Certificate

The National Planning Policy Framework (NPPF) requires most development to undergo the National Permit Register (NPPR) process before it can be built. In certain circumstances, an applicant may be eligible for an exemption or a compliance certificate. This page explains the legal basis, eligibility criteria, the steps involved, and bestpractice tips for preparing a successful application.

1. What is an NPPR Exemption?

An NPPR exemption removes the requirement to obtain a formal planning permission for development that falls within a predefined set of minor works. The exemption is automatically granted when the proposed development meets the conditions set out in Schedule 1 of the Town and Country Planning (General Permitted Development) Order (GPDO) and any relevant local planning policies.

Typical exempted developments

• Small extensions (up to 4m for detached houses, 3m for others)
• Installation of satellite dishes, solar panels, or wind turbines within size limits
• Minor alterations to internal walls and doors
• Change of use from residential to homeoffice, provided floorspace does not increase

2. What is a Compliance Certificate?

A compliance certificate is a formal document issued by the local planning authority (LPA) confirming that a development, which has already been carried out, complies with the conditions of the NPPR or an exemption. It is often required when a property is being sold, mortgaged, or when a subsequent development depends on proof of prior compliance.

When you might need one

• After completing an extension that relied on a permitteddevelopment right
• When a neighbour disputes the legality of a recent work
• To satisfy lenders or insurers during a property transaction

3. Eligibility Key Tests

Both exemptions and compliance certificates are subject to the same fundamental tests:

1. Permitted Development Criteria The work must fall within a category listed in the GPDO and respect any size or location limits.
2. Prior Consultation Certain developments (e.g., solar panels on listed buildings) require prior notification to the LPA.
3. Material Change of Use The use change must not constitute a material change as defined by the GPDO.
4. Neighbouring Impact The development must not significantly affect the amenity, privacy or structural safety of neighbouring properties.
5. Local Policy Compatibility The proposed work must not contradict local development plan policies.

4. StepbyStep Application Process

4.1 Determine Eligibility

Use the Planning Portal's Permitted Development Rights checker or consult your LPAs website. Keep a record of the specific paragraph of the GPDO that applies.

4.2 Prepare Supporting Documents

Even though an exemption does not require formal permission, the LPA may request evidence:

4.3 Submit the Application

Most LPAs accept online submissions via their eplanning portal. Required fields usually include:

• Applicant name and contact details
• Property address and title number
• Reference to the specific GPDO paragraph
• Upload of supporting documents (PDF, JPG, or PNG, max 10MB each)

Pay any applicable fee (usually nominal for exemptions, higher for compliance certificates).

4.4 LPA Review

The authority has 21 days to respond to a compliance certificate request and up to 28 days for an exemption notice. They may request additional information; respond promptly to avoid delays.

4.5 Decision & Issuance

• Exemption Granted You will receive a written confirmation that the development is lawful under permitteddevelopment rights.
• Compliance Certificate Issued The certificate will state that the completed work complies with all relevant regulations, often accompanied by a certificate number for future reference.

5. Common Pitfalls and How to Avoid Them

• Assuming Small Means Automatic Even minor works may require prior notification if they affect a listed building or conservation area.
• Incorrect Measurement Measure to the external face of walls; internal measurements can lead to exceeding permitted dimensions.
• Missing Supporting Documents Incomplete applications are rejected, extending the timeline.
• Ignoring Neighbour Objections If a neighbour raises a valid concern, the LPA can refuse the exemption, forcing a full planning application.

6. Frequently Asked Questions

Do I need a professional architect to apply?

No, an architect is not mandatory for most exemptions. However, for complex works (e.g., loft conversions, structural alterations) a qualified professional can produce accurate drawings and calculations, increasing the chance of success.

Can I appeal a refusal?

Yes. If the LPA refuses an exemption or compliance certificate, you have the right to appeal to the Planning Inspectorate within 21 days of the decision. The appeal must include all original submission material and any new evidence.

How long does a compliance certificate remain valid?

Certificates do not expire, but they are only valid for the specific development described. If you later alter the work, a new certificate may be required.

What is the cost?

Fees vary by authority. Typical exemption confirmation fees range from 030. A compliance certificate can cost between 100300, depending on the complexity and required inspections.

8. Final Checklist Before Submission

1. Confirm the development falls within a permitteddevelopment category.
2. Check local plan policies for any additional restrictions.
3. Gather all required documents (plans, photos, calculations, notification evidence).
4. Complete the online form accurately; doublecheck property details.
5. Pay the correct fee and retain the receipt.
6. Save a copy of the submission confirmation and reference number.

Following these steps will help you navigate the NPPR exemption or compliance certificate process efficiently, minimise delays, and avoid unnecessary costs. If you are ever unsure, seeking advice from a planning consultant or an architect experienced with permitteddevelopment applications can save time and give peace of mind.
