Velux roof windows transform dark loft spaces and enable natural light into converted attics. The correct specification depends on the property type, the planning position, and the roof construction. Conservation specification windows for heritage properties; standard range for residential outside designated areas.

📞 Call Now: 01243 278085The planning position for roof windows varies significantly across the Chichester area. Standard residential properties outside conservation areas have broad permitted development rights. Listed buildings require Listed Building Consent for any addition. Conservation area properties need to consider the visibility of the installation. We assess the consent position at the survey before any installation is committed to.
The conservation Velux range — flush-glazed with minimal visible frame — is the expected specification for Chichester's conservation area properties and listed buildings. At distance the window is barely visible against the tile surface. For standard residential properties outside conservation areas, the standard raised-frame profile is appropriate and significantly cheaper. We stock both ranges and advise on which is correct for your property.
A single Velux on a rear slope not projecting above the ridge is generally permitted development on a standard unlisted property. Front elevation windows, those on listed buildings, those in conservation areas visible from a public road, and any window projecting above the ridge require assessment. We advise specifically on the consent position for your property and position before any installation proceeds.
A standard single Velux installation takes one working day. We open the roof, fit a trimming frame, install the window, fit the tile-specific flashing kit around the outside, and line the internal reveal. At day end the roof is completely weathertight. We never leave an open roof section overnight. For conservation specification windows or multiple-window installations, allow two days.

"Called for double velux installation in loft conversion after another contractor let me down. Professional from first call to completion. Recommend unreservedly."
Bosham is a tidal harbour village with quayside properties within metres of the water. For roofing work in Bosham, this means Salt aerosol concentration here is the highest in the coverage area — marine-spec lead and patination oil are mandatory on all harbour-edge properties. Conservation area around the quay and the historic church. We factor all of this into our survey, specification and material choice on every Bosham job.
We carry patination oil and marine-spec fixings on all vehicles attending Bosham jobs as standard — not as ordered-in extras. The quayside access constraints are familiar and we plan attendance and material delivery around the tidal schedule when required.

The consent position for roof windows in Bosham depends on the property type and location. Standard residential properties in Bosham outside conservation areas have broad permitted development rights for rear slope installations that do not project above the ridge line. For listed buildings — which are present throughout Bosham in various forms depending on the specific area — Listed Building Consent is required for any Velux installation regardless of position. For conservation area properties, the visibility of the installation from a public road and the profile of the window both matter. We confirm the consent position at the survey before any installation is committed to. An installation that requires consent and proceeds without it creates a disclosure obligation when the property is sold.
In Bosham, where tidal harbour quayside properties with maximum salt aerosol, we encounter both conservation area and standard residential properties that require different Velux specifications. The conservation range — flush-glazed with minimal visible frame — is appropriate for heritage properties and any installation where visual impact is a consideration. The standard raised-frame range is appropriate for modern and post-war residential. We stock both and advise on the correct specification at the survey. We also advise on the thermal performance implications of each — modern double and triple-glazed Velux units have centre pane U-values comparable to high-quality vertical windows, but the peripheral frame insulation varies between specification levels.
Standard Velux installation in Bosham costs £450 to £850 for a single window, including the tile-specific flashing kit and internal reveal lining. Conservation specification adds 30 to 50 per cent to the window cost. Replacement of an existing failed Velux unit in the same aperture costs £350 to £700. Written quotes after a free survey. We never leave an open roof section overnight regardless of installation timescale.
