How we approach skylight replacement in St Ives
Thinking about skylight replacement in St Ives? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. In St Ives, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
St Ives sits about 8 km from Huntingdon and 18 km from St Neots, and we cover the whole PE27 postcode district and the roads in between.

What to check first
- A replacement is a chance to meet current thermal standards
- Enlarging the opening changes the structure and may need approval
Planning, building control and St Ives
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.
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. 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.
Read the planning permission guide before you commit to a design.
