Skylight replacement in Oxford: what is involved?
We handle skylight replacement across Oxfordshire, including Oxford. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Skylight replacement suits older extensions due a modern rooflight.
We cover all of Oxford and the OX1 district, and nearby Abingdon and Didcot.
Options we can specify in Oxford
- Dome to flat glass upgrade
- Roof window replacement in pitched roofs
- Like-for-like size replacement
- Fixed to electric opening
- Upstand rebuild and insulation
- Better thermal performance
- Option to add opening and rain sensor
Before you order: points to check
- Enlarging the opening changes the structure and may need approval
- Upstand and roof condition decide the scope
Planning, building control and Oxford
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.

Common questions
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
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.
