Velux Windows in London

A Velux window is a brand of roof window, but the brand is so popular that people often use the name to describe the entire type of window. They are windows that are installed at the same orientation and ‘in plane’ with the surrounding roof, and they’re usually installed at a minimum of a 15-degree pitch. You can buy roof windows that offer completely frameless internal views for a really clean look in your loft conversion, while some come with built-in shutters.

Velux windows aren’t to be confused with rooflights which usually refers to a glazed unit that’s installed on a flat roof. It might also mean a window that’s been installed on a pitched roof out of plane with the level of the tiling.

People also confuse roof windows with skylights, which normally can’t be opened or closed and are usually smaller than Velux windows. Skylights, therefore, only let daylight into the room whereas roof windows also help with ventilation.

If you’re using your loft as a room in your home rather than simply for storage, you must have a roof window installed. Skylights won’t be enough as they don’t allow for ventilation. It doesn’t have to be a Velux window – it can be any type of roof window. Luckily, they tend to come in standard sizes and they must be CE marked if they’re sold as a roof window, so they should be easy to find.

While it sounds like it could be difficult to plasterboard around a Velux window, it needn’t be. As long as you have the right tools and materials, you should be able to plasterboard around your roof window easily and make good ready to be skimmed. When you or a tradesperson has fitted your Velux window into your roof, you’ll probably need to plasterboard over it to create a good ceiling. To do this, you’ll need:

• Plasterboard sheets – make sure you measure your room so you know how much you’ll need
• Screws to secure the board in place
• Drill
• Hammer
• Straight edge and pen knife to score the board before trimming
• Fine toothed saw the cut the plasterboard

When you’re ready to plasterboard around your roof window, make sure you’ve cleared enough space to work in. Then you can begin by cutting your plasterboard to size using your straight edge and pen knife to score, then your saw to get a clean cut. A common way of plasterboarding around your Velux window is to use the groove on the window frame to hold one edge of the board, then screw the other edge to the battens on the ceiling. People often use drywall screws these days as they have a better grip of the plasterboard as they drive through. You’ll need to use a drill to screw these in. However, you could use plasterboard nails, which are galvanised to stop rusting. When you’ve done this, you can then skim the walls or ask a plasterer to do it for you. Plastering, while it looks easy, is a tricky skill so it’s always best to ask a professional to do it.

If you’ve never had Velux windows before, you might be wondering how to open them. If you’ve got very high ceilings and your roof windows are set high up in the pitch of the roof, you might not even be able to reach them. So how do you open them in this case?

When Velux windows are installed so high that they’re out of reach, the installers will often recommend that they install an electric switch for you to open and close your windows. They often come with a rain sensor, so you don’t need to rush up to the top of the house if there’s a sudden downpour – they will close automatically. You can also choose to have a remote so you can open and close your roof windows wherever you are in the room.

If you don’t have an electric switch, but you still can’t reach to open and close your Velux windows, you should be supplied with a telescopic pole when they’re installed. If you weren’t or you’ve moved into a home with roof windows and there isn’t one, you can buy them online. They have a hook on the end and can be extended to the correct length so you can hook it over the handle of the window and pull or push to open it.

If you’ve got a top-hung Velux window that can also be opened in a centre-pivot position, it’s easy to switch between the two. Simply ensure the window is completely closed before you start, then open the handle up – but don’t push it out. Then pull the vent bar down until the sash is rotated 180 degrees. Then secure the position by sliding the barrel bolts into the holes at either side of the bottom of the frame. Easy!

In general, no – you don’t need planning permission for a Velux window. The Planning Portal says that you don’t need to apply for planning permission to install a roof window if the following conditions are met:

• A roof window must not protrude more than 150 millimetres above the existing roof plane
No roof window or any other alteration can be higher than the highest part of the roof or stand out above the roof ridge
• Side-facing windows must have obscure glazing to protect privacy of neighbours and, if they open, they must be 1.7 metres above the floor of the room in which they are installed

You don’t need to apply for planning permission for a roof window because they are covered under permitted development rights. However, if you’re a leaseholder or you live in a building where your local authority has made an Article 4 Direction, you will have to apply. Usually, an Article 4 Direction is made when you live in a conservation area where any external home improvements could affect the character and look of the area. Luckily, there are special Velux windows that are designed to be more likely to be accepted by your local planning authority. They’re called conservation windows and, although there’s still no guarantee that they will be accepted, they are designed to look more traditional. Even if you don’t need planning permission for your roof window, you still need to follow any relevant building regulations for your local authority. The most important parts for Velux windows are section J and section L of building regulations, which refer to energy efficiency, thermal insulation and fire protection.
