What do sliding rooflights in Winchester involve?
Our sliding rooflights service in Winchester covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of sliding rooflights for staircases that rise to a roof terrace.
Winchester is around 19 km from Southampton, and we survey and fit throughout that part of Hampshire, including the SO23 district.

Planning and building rules for Winchester
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

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.
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 it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Do you fit sliding rooflights in Winchester?
Yes. We survey and fit sliding rooflights in Winchester and across Hampshire. Send your postcode and we will offer a survey date when we reply.
Is the survey in Winchester free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
