How we approach skylight replacement in Nelson
For Nelson homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Skylight replacement suits older extensions due a modern rooflight.
We work across Lancashire, including Nelson, and in neighbouring towns such as Colne and Burnley. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Roof window replacement in pitched roofs
- Upstand rebuild and insulation
- Fixed to electric opening
- Like-for-like size replacement
- Dome to flat glass upgrade
- Better thermal performance
- Clearer view and more light
What to check first
- A replacement is a chance to meet current thermal standards
- Upstand and roof condition decide the scope
Do you need permission in Nelson?
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. 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.
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. 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.

Skylight replacement in Nelson: questions
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.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Is the survey in Nelson 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 Nelson?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
