Skylight replacement in Wiltshire: the essentials
Skylight replacement in Wiltshire means replacing tired domes and failed glass with a modern rooflight. Every quote follows a survey of the roof and the room below.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure.

Planning and building rules in England
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Common questions
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Do you offer skylight replacement across Wiltshire?
Yes. We carry out skylight replacement across Wiltshire, including Swindon, Salisbury, Trowbridge.
