How we approach skylight replacement in Widnes
Our skylight replacement service in Widnes covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Think of skylight replacement for older extensions due a modern rooflight.
We work across Cheshire, including Widnes, and in neighbouring towns such as Runcorn and Halewood. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Widnes?
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.
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. 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.
Read the planning permission guide before you commit to a design.

Questions about skylight replacement in Widnes
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
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.
Do I need to be at home for the survey in Widnes?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Widnes?
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.
