What do loft conversion skylights in Stevenage involve?
We handle loft conversion skylights across Hertfordshire, including Stevenage. In short: roof windows planned for loft rooms — light, headroom and escape. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Stevenage, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
From Stevenage to Hitchin, Letchworth Garden City and Welwyn Garden City, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for loft conversion skylights in Stevenage
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.
