How we approach sliding rooflights in Daventry
Our sliding rooflights service in Daventry 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.
Midlands housing is a mix of Victorian terraces, inter-war semis and newer estates, and rear kitchen extensions with flat rooflights are a common upgrade. In Daventry, as anywhere, sliding rooflights are the usual choice for staircases that rise to a roof terrace.
We work across Northamptonshire, including Daventry, and in neighbouring towns such as Rugby and Towcester. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Daventry
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.
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.
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 the survey in Daventry free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Daventry?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
