Electric Velux Windows Fitted in a Surbiton Loft

New electric Velux roof window fitted into the pitched roof of a Surbiton loft, with blue sky and neighbouring rooftops beyond

A homeowner in Surbiton wanted to bring natural light and ventilation to a dark loft space. The answer was two new electric Velux roof windows, fitted into the pitched roof, turning a space lit by a single bulb into one with daylight and fresh air on demand.

A loft in the dark

Before we started, the loft was exactly what you would expect: bare rafters, roofing membrane, and no natural light at all. Any time spent up there meant working by torchlight or a single bulb, with no way to let fresh air through the space.

Opening up the roof

Working from inside the loft, we stripped back the membrane, cut the openings, and trimmed the rafters to form two structural openings ready to take the new windows. Each opening was framed out so the Velux units would sit square, supported, and perfectly in line with the roof.

Windows in, light on

With the frames secured, flashed, and weatherproofed, the glazed units went in and the tiles were dressed back around each window. The change inside was immediate: two big rectangles of sky where there had only been darkness, and with the electric motors and remote control, fresh air through the loft at the touch of a button. The integrated rain sensor closes each window automatically if the weather turns.

Frequently asked questions

What is the difference between electric and solar Velux windows?

Both are motorised and remote controlled. Electric Velux windows are powered from the mains, while solar versions run on a battery charged by a small integrated solar panel. Electric models suit lofts where a power supply is available, and both include a rain sensor that closes the window automatically in wet weather.

Do Velux roof windows need planning permission?

In most cases, no. Roof windows on a house usually fall under permitted development, provided they do not protrude significantly above the roof plane. Homes in conservation areas or listed buildings are the exception, so it is always worth checking with your local authority first.

Why add roof windows to an unconverted loft?

Natural light and ventilation transform how usable a loft is, whether it is a storage space, hobby room, or a future conversion project. Roof windows let daylight flood in, release trapped heat in summer, and let you air the space out, all of which help keep a loft dry and pleasant.
