A refusal is frustrating, but it is rarely the end of the project. Most householder refusals come down to a small number of design issues that can often be addressed.
Step 1: Read the reasons for refusal
Your decision notice lists the specific reasons the council refused your application. These are what any next step has to address. Common reasons for extensions and loft conversions include:
- Impact on neighbours — loss of light, an overbearing or overshadowing effect, or overlooking and loss of privacy.
- Design and character — scale, roof form, materials or bulk out of keeping with the house or street.
- Conservation areas — harm to the character or appearance of the area.
- Green Belt — extensions considered disproportionate to the original building.
Also read the case officer's report, usually published alongside the decision on the council's planning website. It often shows what the council might have accepted.
Option 1: Revise the design and resubmit
For most householder refusals this is the quickest and most reliable route. A revised scheme that clearly addresses each reason for refusal — for example reducing depth or height, changing the roof form, moving windows, or stepping the extension away from a boundary — can often be approved.
Tip: in your resubmission, explain briefly how each reason for refusal has been addressed. It helps the case officer and shows the scheme has changed.
Option 2: Appeal to the Planning Inspectorate
If you believe the council got it wrong, you can appeal to the Planning Inspectorate, which is independent of the council.
Key points for householder appeals:
- Deadline: 12 weeks from the date on your decision notice. Miss it and you lose the right to appeal.
- Who can appeal: only the applicant.
- Process: usually written. You submit your case and supporting information at the outset, an inspector visits the site, and a written decision follows.
- The same scheme: an appeal considers the proposal that was refused. You can't use it to submit a different design.
- Timescales vary, and an appeal can take longer than a revised application.
An appeal tends to suit cases where the scheme is reasonable and the refusal reasons are weak or inconsistent with similar approvals nearby.
Option 3: Check the permitted development route
Some extensions, loft conversions and garage conversions can be built under permitted development rights, without a planning application — within strict size and design limits, and not in every location (for example, rights are reduced in conservation areas). A slightly smaller or reshaped scheme may fit.
If you go this route, a Lawful Development Certificate gives you formal confirmation that the work is lawful — useful when you come to sell. In England the application fee for a proposed development is half the equivalent planning fee.
Can I do more than one?
Yes. Some homeowners appeal the original scheme while submitting a revised design at the same time, or build a permitted development scheme while appealing. Each route has its own cost, so it is worth weighing them up before committing.
Which option is right for you?
| Situation | Usually the best first step |
|---|---|
| Refused for neighbour impact or scale | Revise and resubmit |
| Refusal reasons look weak or inconsistent | Consider an appeal (within 12 weeks) |
| Scheme is close to permitted development limits | Check permitted development and apply for an LDC |
| Conservation area or Green Belt | Revise carefully against local policy |

Frequently asked questions
For a householder application in England, 12 weeks from the date on the decision notice.
Not in England any more. The free resubmission was removed from 6 December 2024. A householder application costs £548 from 1 April 2026.
There is no fee to lodge a householder planning appeal with the Planning Inspectorate in England, but you may pay for professional help preparing your case.
No. Only the applicant can appeal a refusal.
Possibly, if the scheme meets all the permitted development limits for your property. A refusal does not remove your permitted development rights, but those rights may already be restricted on your property — check before you start.
This guide reflects the position in England as of October 2026. Planning rules vary by property and location; always check your decision notice and your council's guidance.
