Roof windows don’t just let more light in – they can completely transform your home. But sometimes, you might need planning permission depending on where you live and the work you want to do. Get clued up with our guide.
1. Most VELUX roof windows don't need planning permission. If your installation meets exempted development, you could install a roof window without making a planning application.
2. Some homes have different rules. Protected structures, Special Areas of Conservation (SAC) and properties with removed exempted development usually need planning permission before work can begin.
3. Planning permission and building regulations aren't the same. Even if planning permission isn't needed, your installation might still need to comply with building regulations.
What does ‘exempted development’ mean for roof windows?
Certain home improvements don't need planning permission because they're classed as exempted development. These rules are part of the Planning and Development Act and Regulations, and cover smaller projects such as roof windows, garden sheds and minor house extensions with the aim of saving homeowners time and money.
Most VELUX roof windows are designed to sit neatly within existing roof slopes. That means they often fall within the size and projection limits set out under exempted development, making them a popular choice for loft conversions and attic renovations.
Exempted development doesn't mean there are no rules, though. Your roof window still needs to meet certain requirements, and some properties might have extra planning restrictions that you’d need to be aware of.
When doesn't a VELUX roof window need planning permission?
Most VELUX roof windows can be installed without planning permission if they meet the conditions for exempted development. These are in place to make sure the work doesn't drastically alter the appearance of your home or affect your neighbours’ properties.
As a guide, exempted development usually means your roof window should:
- Fit within the conditions for exempted development set out in Irish planning regulations
- Comply with any conditions that apply to your property, particularly if it's a protected structure or located in an Architectural Conservation Area (ACA)
- Meet the relevant building regulations, even when planning permission isn't required
As every property is different, it's always worth checking with your local planning authority before you start any work, especially if your home is in a Special Areas of Conservation (SAC) or is a heritage home.
When do you need planning permission in Ireland?
Some roof window projects fall outside exempted development and will need planning permission. This doesn't necessarily mean your project can't go ahead, but it does mean you'll need approval from your local planning authority first.
Examples of projects needing planning permission include:
- When your home is in Special Areas of Conservation (SAC) or another protected location
- When your property is a protected structure
- When exempted development has been removed or doesn’t apply
- When your installation doesn't meet the standard exempted development conditions
Do SACs and protected structures have different planning rules?
Yes. Homes in Special Areas of Conservation (SAC), national parks, Areas of Outstanding Natural Beauty (AONBs), World Heritage Sites and protected structures often have additional planning restrictions which help preserve their character and appearance.
If your home is a protected structure, you might need additional permissions. The Citizens Information website has a helpful guide for protected structures.
What kinds of projects need planning permission?
For any work on your house, we recommend checking with your builder, installer and local authority to know what applies to your property and the area you’re in. But as a quick guide, here’s when you might need planning permission for.
Situation
Is planning permission needed?
Standard pitched VELUX roof window
Usually no
Protected structure
Almost always
Special Areas of Conservation (SAC)
Almost always
Roof alterations outside exemptions
Usually yes
Do you still need building regulations approval?
You might have come across building regulations approval and wonder how it’s different from planning permission. Building regulations make sure the work meets the standards for things like structural safety, fire safety, ventilation and energy efficiency. Whereas planning permission is about how the work affects your property and the surrounding area.
But don’t worry about having to know everything. Your installer or building team should be able to tell you which regulations apply to your project and whether approval is needed before the work starts.
How can you check before you install a roof window?
If you're unsure whether planning permission is needed, we recommend checking before you start any home improvement project. A quick chat with your local planning authority can give you peace of mind and help avoid delays once your project is underway.
It's also worth speaking to an experienced installer early in the process. They can help you choose the right roof window, explain what's involved and point out any planning or building regulations you need to consider.
For extra confidence, try choosing a VELUX Certified Installer. All of our installers are fully trained, vetted and insured, giving you reassurance that your roof window will be installed to a high standard.

Planning permission for VELUX windows: your questions
Can you put a VELUX roof window in without planning permission?
The good news is yes. Most VELUX roof windows can be installed under exempted development without planning permission if they meet the relevant local conditions and your property doesn't have additional planning restrictions. We recommend checking with your local planning authority before you begin any work.
Does a loft conversion need planning permission if you're installing roof windows?
Not always. Lots of loft conversions using roof windows can be completed under exempted development, as long as the project meets the relevant planning conditions. Larger projects, such as installing a dormer or extending beyond exempted development rules, are more likely to require planning permission. Your builder or installer should be able to advise you on this.
What's the difference between planning permission and building regulations?
Planning permission is concerned with how a development affects the appearance and use of a property or the surrounding area. Building regulations focus on how the work is carried out, covering areas such as structural safety, fire safety, ventilation and energy efficiency. In some projects you'll need both, while others might only need building regulations approval.
What should you do if you’re unsure about planning permission?
If the guidance isn't clear or your property has unusual planning restrictions, we recommend asking your local planning authority before you start anything. They’ll be able to confirm whether planning permission is needed and help you understand the rules that apply to your home.
