Roof lanterns in Thatcham: what is involved?
Our roof lanterns service in Thatcham covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Roof lanterns suit orangeries, kitchen-diners and single-storey extensions.
Neighbouring towns include Newbury (4 km) and Basingstoke (20 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Thatcham
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. 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.
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.

Common questions
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.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Do I need to be at home for the survey in Thatcham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Thatcham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
