Sliding rooflights in Powys: the essentials
Sliding rooflights in Powys means box rooflights whose glass lid slides back for walk-out roof access. Every quote follows a survey of the roof and the room below.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere.

Planning and building rules in Wales
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Common questions
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 a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Do you fit sliding rooflights across Powys?
Yes. We survey and fit sliding rooflights across Powys, including Brecon, Llandrindod Wells, Machynlleth.
