Loft conversion skylights for Sherborne: the essentials
For Sherborne homes and buildings we offer loft conversion skylights: roof windows planned for loft rooms — light, headroom and escape. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Loft conversion skylights suit loft conversions and rooms in the roof.
Sherborne sits about 8 km from Yeovil and 26 km from Dorchester, and we cover the whole DT9 postcode district and the roads in between.

Planning, building control and Sherborne
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. 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. 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.
Our planning guide covers each nation in more detail.

Common questions
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
Will I need planning permission in Sherborne?
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.
Is the survey in Sherborne free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
