Sliding rooflights for Hythe: the essentials
Thinking about sliding rooflights in Hythe? The short answer: box rooflights whose glass lid slides back for walk-out roof access. The longer answer depends on your roof, which is why we survey before we price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for sliding rooflights include walk-out access where a hatch would feel cramped.
Hythe is around 5 km from Southampton, and we survey and fit throughout that part of Hampshire, including the SO45 district.

What to check first

Do you need permission in Hythe?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

Questions about sliding rooflights in Hythe
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
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.
Is the survey in Hythe free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Hythe?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
