Rectangular roof lanterns for Heston homes
The classic double-hipped lantern: a ridge, four sloping sides and the most size choice.
In midsummer the noon sun stands about 62.0° high over Heston, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Ridge along the long axis, four glazed slopes
- Standard sizes or made to your kerb
- Stock anthracite, black or white, or any RAL

Planning and building regulations for Heston
England's Approved Document L caps the U-value of new or replacement rooflights in existing homes at 2.2 W/m²K, calculated with the glass horizontal.
On a permitted development extension the lantern counts towards the extension's height; on an existing roof, a rooflight projecting more than 150 mm may need planning permission.
Building regulations in Heston are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Heston
Which way should the ridge run?
The ridge runs along the longer side. On a square opening there is no ridge and the lantern becomes a pyramid.
Can a rectangular lantern be made to an exact size?
Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.
How quickly can I get a roof lantern in Heston?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for TW5.
Who checks building regulations for a lantern in Heston?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
