How we approach skylight replacement in Cheltenham
Our skylight replacement service in Cheltenham 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Think of skylight replacement for older extensions due a modern rooflight.
Cheltenham sits about 12 km from Tewkesbury and 12 km from Gloucester, and we cover the whole GL50 postcode district and the roads in between.

Things we check at survey
- Enlarging the opening changes the structure and may need approval
- Upstand and roof condition decide the scope
Planning, building control and Cheltenham
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Questions about skylight replacement in Cheltenham
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 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.
Is the survey in Cheltenham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Cheltenham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
