Roof lanterns in Flitwick: what is involved?
Thinking about roof lanterns in Flitwick? 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. Roof lanterns suit orangeries, kitchen-diners and single-storey extensions.
Neighbouring towns include Ampthill (3 km) and Dunstable (13 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Flitwick?
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about roof lanterns in Flitwick
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
Do I need to be at home for the survey in Flitwick?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Flitwick free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
