What do loft conversion skylights in Hitchin involve?
Thinking about loft conversion skylights in Hitchin? The short answer: roof windows planned for loft rooms — light, headroom and escape. The longer answer depends on your roof, which is why we survey before we price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for loft conversion skylights include loft conversions and rooms in the roof.
Hitchin is around 34 km from Watford, and we survey and fit throughout that part of Hertfordshire, including the SG4 district.

Planning, building control and Hitchin
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Common questions
Will the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
Do I need to be at home for the survey in Hitchin?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Hitchin?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
