Conservation rooflights in Southampton: what is involved?
Thinking about conservation rooflights in Southampton? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. 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. Conservation rooflights suit slate and plain-tile roofs where a quiet roofline matters.
Southampton is the main town we list in Hampshire; we also cover nearby Hythe and Totton.
Options we can specify in Southampton
- Central vertical glazing bar
- Flashings for slate or plain tile
- Manual or electric opening
- Toughened or laminated double glazing
- Blinds
- Steel or aluminium frame in black or grey
- Traditional slim profile, sits low in the roof
Things we check at survey
- Listed building consent is needed for listed buildings
- Projection above the roof line is limited — usually as flush as possible
Do you need permission in Southampton?
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
