What do commercial & industrial rooflights in Llanelli involve?
Commercial & industrial rooflights in Llanelli means rooflights for warehouses, schools, offices and retail units. We cover the SA15 district and the rest of Dyfed, with a survey before any price is fixed.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Typical uses for commercial & industrial rooflights include warehouses, schools, offices and retail units.
We cover all of Llanelli and the SA15 district, and nearby Gorseinon and Swansea.

Building control and safety duties in Llanelli
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.
