What does skylight replacement in Dulwich involve?
We handle skylight replacement across Greater London, including Dulwich. 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. In Dulwich, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
From Dulwich to Brixton, Peckham and Lewisham, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Dulwich
- Dome to flat glass upgrade
- Misted glass unit replacement only
- Upstand rebuild and insulation
- Roof window replacement in pitched roofs
- Fixed to electric opening
- Clearer view and more light
- Better thermal performance
Things we check at survey
- Enlarging the opening changes the structure and may need approval
- Upstand and roof condition decide the scope
Planning and building rules for Dulwich
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
