Planning and building rules in England
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.

Skylight questions: Lancaster
Is the survey in Lancaster free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Lancaster?
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 Lancaster?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Lancaster?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do you take a deposit?
Nothing is paid until you accept a written quote. Made-to-measure products are ordered after you accept, we tell you in writing when the order is placed, and the quote states the payment stages.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
