Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos from Horsham (RH12) and we'll tell you which it is — with the price agreed in writing before any work.

About Horsham and the RH12 area
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Horsham is around 25 miles from Chichester, and both are within our West Sussex coverage.
We also cover nearby Crawley (7 miles), Horley (11 miles), Haywards Heath (11 miles).
What should you expect to pay in Horsham?
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
