Sliding rooflights for Welshpool: the essentials
We handle sliding rooflights across Powys, including Welshpool. In short: box rooflights whose glass lid slides back for walk-out roof access. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Sliding rooflights suit walk-out access where a hatch would feel cramped.
Welshpool sits about 19 km from Newtown and 39 km from Rhosllannerchrugog, and we cover the whole SY21 postcode district and the roads in between.
Specification options
- Box (glazed sides) or flat sliding lid
- Electric drive with safety edge
- Double or triple glazing
- Integrated balustrade on some ranges
- Anthracite, black or RAL frames
- Replaces a dormer or stair enclosure on some roofs
- Full-width, walk-out access to a roof terrace
Before you order: points to check
- Weight and point loads need a structural check
- Needs space on the roof for the lid to slide clear
Planning and building rules for Welshpool
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. 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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Common questions
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.
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.
Will I need planning permission in Welshpool?
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.
How do I book a survey in Welshpool?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
