How we approach sliding rooflights in Crowthorne
Sliding rooflights in Crowthorne means box rooflights whose glass lid slides back for walk-out roof access. We cover the RG45 district and the rest of Berkshire, with a survey before any price is fixed.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of sliding rooflights for walk-out access where a hatch would feel cramped.
Crowthorne is around 16 km from Reading, and we survey and fit throughout that part of Berkshire, including the RG45 district.

Do you need permission in Crowthorne?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
Do I need to be at home for the survey in Crowthorne?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Crowthorne free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
