If you are reading this, you probably have a draughty, misty, or leaking roof window, and you want a straight answer: How much is this going to cost?
Quick Cost Summary (2026 Estimates)
For a standard Velux window replacement in Yorkshire, prices typically range from £1500 to £2500High Estimate] fully installed.
This price generally covers the new window unit, a new flashing kit, all labour, and waste disposal. However, the final figure depends on three key things: the size, the operation method (manual vs. solar), and your specific roof material.
Now that you have the ballpark figure, let’s break down exactly where your money goes and how hiring Yorkshire Roof Windows specialists & trained professionals can actually cost you less than a general builder.
Breakdown of Supply & Fit Costs
When researching the Velux window replacement cost, it is easy to get confused by “supply only” prices online. Remember, a window in a box won’t keep your house warm. You are paying for a weather-tight installation.
Below is a guide to our pricing based on the most common standard Velux window size configurations we see in homes across Leeds, York, and Hull.

Note: You can usually find your existing Velux window codes on a small metal plate located on the top edge of the sash when the window is open.
Do You Need Scaffolding to Replace Windows?
This is the most common question we get, and the answer might save you a fortune.
If you search “do you need scaffolding to replace windows,” many general construction sites will say “Yes.” If you hire a general builder or a roofer, they will almost certainly charge you an extra £400 to £600 to erect a scaffold tower.
Here is the Yorkshire Roof Windows difference:
Because we are trained specifically in Velux products, we have mastered the technique of installing replacements entirely from the inside of the room.
By avoiding this unnecessary expense, many of our clients find they can afford to upgrade to a white polyurethane finish or a solar-powered model for the same total price they were quoted elsewhere for a basic job.
3 Factors That Influence Your Quote
Every home in Yorkshire is unique. When we provide a fixed quote, we check three critical factors:
1. The “Yorkshire Stone” Factor
Our region is famous for its beautiful stone roofs. However, stone slates are thicker and heavier than standard tiles.
- Standard Tiles: Use a standard flashing kit.
- Yorkshire Stone: Requires a specialized plain tile or slate flashing kit with deeper soakers.
Using the wrong flashing is the #1 cause of leaks we see. We ensure the correct kit is included in your price from day one.
2. The Internal Finish
- White Painted: The standard modern choice for bedrooms.
- White Polyurethane: A maintenance-free, moisture-resistant core. We highly recommend this for bathrooms and kitchens to prevent rot.
3. Repair vs. Replace
Sometimes, you don’t need a whole new window. If your timber frame is in perfect condition but the glass has failed (misty or condensation inside the pane), we can offer replacement glass for velux windows.
This service, often called “reglazing,” is significantly cheaper than a full replacement. However, if your frame is over 20 years old or showing signs of black mould, a full replacement is usually more cost-effective in the long run.
Why Choose a “Trained Professional” vs. a General Builder?
You might see a slightly lower labour rate from a “man in a van” on Facebook. But consider this: Velux windows are complex engineering systems.
An untrained fitter often:
- Over-compresses the insulation collar (causing cold draughts).
- Misses the vapour barrier connection (leading to damp).
- Uses the wrong flashing for the roof pitch.
As dedicated roof window installers in Yorkshire, we carry the correct tools and spare parts to handle unexpected issues on the spot. We don’t just “fit” a window; we protect your roof void from the damp British weather.
