Important: Additional Restrictions May Apply in Isle of Wight

What About Building Regulations?
Building regulations approval is not usually required
Greenhouses are normally exempt from Building Regulations as single-storey outbuildings under 30 square metres with no sleeping accommodation. Any electrical installation must comply with Part P.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Isle of Wight building control or use an approved inspector.
How to Apply in Isle of Wight
If you need planning permission for your greenhouse, you can apply through Isle of Wight's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Isle of Wight. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Very low risk for domestic greenhouses within PD limits. Enforcement is rare unless the greenhouse is unusually large or used for commercial purposes.
