How we approach skylight replacement in New Milton
For New Milton homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In New Milton, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
New Milton is around 25 km from Southampton, and we survey and fit throughout that part of Hampshire, including the BH25 district.
What you can choose
- Like-for-like size replacement
- Roof window replacement in pitched roofs
- Upstand rebuild and insulation
- Misted glass unit replacement only
- Dome to flat glass upgrade
- Better thermal performance
- Cures most chronic leaks
Before you order: points to check
- Upstand and roof condition decide the scope
- Enlarging the opening changes the structure and may need approval
Planning, building control and New Milton
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. 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. 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.

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.
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.
Do I need to be at home for the survey in New Milton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in New Milton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
