A single Velux window installed into an existing pitched roof in Llandudno typically costs £800–£1,400 depending on window size, roof covering type, and lead flashing specification. Multiple windows on the same visit reduce per-unit cost. We supply at trade prices and include all flashings and surrounding tile/slate redressing.
In most cases, Velux windows are permitted development as long as they don't protrude more than 150mm from the existing roof plane. Properties within Llandudno conservation area, listed buildings, or designated areas may require Conwy County Borough Council consent. We advise before quoting.
