Towns we list in Cornwall
Our fitting teams travel across Cornwall, so coverage depends on your address rather than on where an office sits. Most addresses in England are standard cover. Remote and island locations, where they apply, are by arrangement, and we confirm that before quoting so there is no confusion later about dates or travel costs.
The Isles of Scilly are covered by arrangement, with travel priced into the quote before you commit.

Planning and building regulations in England
England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.
Questions about rooflight fitting in Cornwall
Do you cover Cornwall?
Yes, with some addresses by arrangement. Mainland towns are covered in the usual way. Island and remote addresses are taken on case by case, with travel, dates and any ferry costs confirmed in the written quote before you commit.
Do I need planning permission for a rooflight in Cornwall?
Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.
Can you fit a rooflight in winter or when it is raining?
Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
Will my new rooflight leak?
A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
