Roof lanterns for High Wycombe: the essentials
For High Wycombe homes and buildings we offer roof lanterns: hipped glass lanterns that lift the ceiling of orangeries and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In High Wycombe, as anywhere, roof lanterns are the usual choice for orangeries, kitchen-diners and single-storey extensions.
From High Wycombe to Amersham, Maidenhead and Chesham, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Solar-control or self-cleaning glass
- Internal and external colours
- Rectangular, square or bespoke sizes
- LED lighting in the plaster box
- Aluminium or uPVC systems
- Slim aluminium bars, more glass
- Adds visual height to a single-storey room
Before you order: points to check
- Needs a strong, level kerb or upstand
- Some designs project above the roof enough to affect planning on certain houses
Planning, building control and High Wycombe
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
Read the planning permission guide before you commit to a design.

Common questions
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.
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.
Will I need planning permission in High Wycombe?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
Do I need to be at home for the survey in High Wycombe?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
