In Daventry, as everywhere, opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos and we'll tell you what we think has failed.

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

How much should it cost?
Most opening vent and actuator repairs jobs come in between £195 and £545 ex VAT (£234–£654 including VAT), per vent. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
