Skylight replacement for Witham: the essentials
Our skylight replacement service in Witham 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.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. In Witham, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
From Witham to Maldon, Braintree and Chelmsford, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Upstand rebuild and insulation
- Like-for-like size replacement
- Roof window replacement in pitched roofs
- Fixed to electric opening
- Dome to flat glass upgrade
- Clearer view and more light
- Option to add opening and rain sensor
Things we check at survey
- A replacement is a chance to meet current thermal standards
- Upstand and roof condition decide the scope
Do you need permission in Witham?
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.
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. 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 replacement in Witham: questions
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Is the survey in Witham 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 Witham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
