Where is the VELUX window code and why does it matter?

If you contact AR Windows about a VELUX repair, replacement part, blind, glazing issue or maintenance visit, one of the most useful pieces of information you can provide is the VELUX window code.

This code helps identify the roof window model, size and type. It can make it much easier to advise on the right next step, whether that is repair, maintenance, replacement parts, blinds or a full replacement roof window.

What is a VELUX window code?

The VELUX window code is a product identification code linked to the roof window. It usually includes information about the window type and size. This helps distinguish one model from another, especially when several roof windows look similar from inside the room.

The code is particularly useful because small differences in model, age or size can affect which parts, blinds, glazing or replacement options are suitable.

The code can help identify:

• the VELUX window model
• the size of the roof window
• the type of operation
• possible compatible blinds
• possible replacement parts
• whether repair or replacement advice is likely to be more suitable

Where do you find the VELUX code?

The code is usually found on the window itself, often on a data plate or identification plate. The exact position can vary depending on the window model and age.

On many VELUX roof windows, the plate can be found when the window is opened or rotated. However, you should only look for it if the window is safe and easy to operate.

Before checking the code:

• make sure the window is safe to reach
• do not lean out of the opening
• do not force a stiff or stuck window
• do not climb or work at height
• take a photo if the plate is visible
• stop if the window feels unsafe or unstable

If the window is high, stuck, damaged or difficult to open, do not attempt to access the plate. Send general photos instead and ask AR Windows for advice.

Why does the VELUX code matter for repairs?

When a VELUX window develops a fault, the code can help identify the window more accurately. This can be useful when considering whether replacement parts may be available or whether the issue is likely to need a broader repair assessment.

The code can help with repair advice for:

• stiff or difficult-to-operate windows
• broken handles or locking issues
• worn seals or hinges
• misted or failed glazing
• blind compatibility
• older windows where parts may be harder to identify

The code does not replace a proper inspection, but it gives a much stronger starting point.

What if you cannot find the code?

Do not worry if you cannot find the VELUX window code. It is helpful, but it is not the only way to begin an enquiry. Good photos and a clear description can still help AR Windows understand the issue.

Never force a window open just to find the code. If the window is stiff, stuck or damaged, forcing it can make the problem worse.

Why the code matters for VELUX blinds

VELUX blinds are model and size dependent. The correct blind needs to match the roof window properly. This is one of the reasons the window code can be very helpful.

If you are asking about VELUX blinds, send the code if you can. This helps avoid guesswork and makes it easier to advise on suitable options.

Why the code matters for replacement windows

If your roof window is old, leaking, misted, draughty or difficult to use, replacement may be worth considering. The VELUX code can help identify the existing window and support a more informed replacement discussion.

Replacement may be worth discussing if:

• the window has repeated leaks
• the glazing has failed or misted
• the window is very stiff or unreliable
• the frame, seals or components are worn
• repair costs are becoming poor value
• you want improved comfort, usability and reliability

You can learn more on the replacement windows page.

What should you send with a VELUX enquiry?

Whether or not you have the code, clear information makes it easier to advise on the next step.

Helpful information includes:

• a photo of the VELUX product code or plate if safe to access
• photos of the full window from inside the room
• close-up photos of any damage, leak, misting or worn part
• a short description of the problem
• whether the issue happens during rain, cold weather or normal use
• the approximate age of the window if known
• details of access if the window is high or difficult to reach

Can AR Windows help if the code is missing or unreadable?

Yes. If the code is missing, worn, painted over or impossible to access safely, AR Windows can still start with photos and a description.

Depending on the issue, the team may be able to advise on likely next steps or recommend a maintenance, repair or replacement assessment.

Final thoughts

The VELUX window code is a small detail that can make a big difference. It helps identify the roof window more accurately and can support better advice on repairs, parts, blinds, glazing, maintenance and replacement.

If you can find it safely, take a clear photo and send it with your enquiry. If you cannot, do not force the window. Send photos and details instead, and AR Windows can help guide you from there.
