London loft: Roof windows replaced in an afternoon

See how this London loft was transformed in less than four hours with a VELUX roof window replacement. The space is now futureproofed for another generation, and ready to take on all seasons, with the addition of new external shutters.

Time to replace

Meet James who lives in Raynes Park, South West London. He’s lived here for almost 20 years in the family home. The loft conversion was first built in 2008 and designed with two VELUX roof windows to bring an abundance of daylight to the new space.

Fast forward to 2026. While their old VELUX roof windows have lasted well, the family felt it was time to use the Replacement Supply & Fit Service to upgrade them with two new VELUX top-hung, white maintenance-free roof windows.

Why have new roof windows when the old ones were fine?

The roof windows were almost 20 years old, and the family had outgrown the look and functionality of the old roof windows. They wanted to modernise the interior, improve insulation and indoor comfort, while bringing more convenience to the home.

"The VELUX roof windows we had were really solid and did a good job for us over the years, so it made sense to stay with VELUX. Especially when the sizes match and the range of choices are really good."

With a whole host of options available, the family decided to change their old pine centre-pivot roof windows to white-maintenance-free with top-hung functionality. This now allows them to open the roof windows outwards, so they can enjoy an unobstructed view with plenty of daylight. Their choice of white maintenance-free finish now fits seamlessly with the décor of the home and brightens the room.

"Having top-hung roof windows will be a lot better for us, you get a better view when you open the window and it will let plenty of air through. The white finish matches a lot better to the rest of the white paintwork in the room."
James

Reassured from the moment of enquiry

The family liked the idea of adding VELUX anti-heat blackout shutters to keep out unwanted heat in the summer months - and add further insulation in the winter. To understand the shutter options available, they reached out to the VELUX Replacement Supply & Fit Service team with their query.

James: "The replacement team gave me a call back and reassured me it’s possible and that we could do that - so it was great to go ahead."

Using VELUX Certified Installers for the best result

James: "Having Ross and the team - the VELUX Certified Installers - was the best choice for us. They did a really clean job and everything matched perfectly. They were in quickly, did the work, tidied up and it was all done much faster than I expected."

The new VELUX roof windows were able to fit into existing roof openings, which meant no structural work or redecoration was required. The replacement transformation took place in just a few hours, ensuring the bedroom space was restored by the afternoon.

Would they recommend replacing? Without hesitation

James: "If someone asked me, would I recommend the VELUX Supply and Fit Service? I’d say absolutely.

"It’s one of those bits of the house that you can’t take a chance on because it gets so much exposure to the weather. Getting something that is technically competent and not taking the cheap option is the best way forward."

"My favourite part of the whole thing is seeing the new windows in place because it makes a bigger difference to the room than I thought it would."
