Skylight replacement in Horley: what is involved?
Skylight replacement in Horley means replacing tired domes and failed glass with a modern rooflight. We cover the RH6 district and the rest of Surrey, with a survey before any price is fixed.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Horley, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
We work across Surrey, including Horley, and in neighbouring towns such as Crawley and Redhill. 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
- Fixed to electric opening
- Misted glass unit replacement only
- Dome to flat glass upgrade
- Like-for-like size replacement
- Often reuses the existing opening
- Usually done in a day
What to check first
- Upstand and roof condition decide the scope
- Enlarging the opening changes the structure and may need approval
Planning and building rules for Horley
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. 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. 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
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
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.
Will I need planning permission in Horley?
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.
Do I need to be at home for the survey in Horley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
