Sliding rooflights in Ashton-in-Makerfield: what is involved?
Our sliding rooflights service in Ashton-in-Makerfield 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. In Ashton-in-Makerfield, as anywhere, sliding rooflights are the usual choice for staircases that rise to a roof terrace.

Planning and building rules for Ashton-in-Makerfield
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

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.
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.
