Roof lanterns in New Milton: what is involved?
Thinking about roof lanterns in New Milton? The short answer: hipped glass lanterns that lift the ceiling of orangeries and extensions. The longer answer depends on your roof, which is why we survey before we price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of roof lanterns for orangeries, kitchen-diners and single-storey extensions.
From New Milton to Christchurch, Bournemouth and Hythe, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in New Milton?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about roof lanterns in New Milton
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Will I need planning permission in New Milton?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
How do I book a survey in New Milton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
