West Sussex: uPVC double glazed windows
When windows are replaced in England, Approved Document F expects the room's ventilation to be no worse than before. That usually means trickle vents in the head of the new frames, sized to the room, so the glazier records whether the old windows had vents and specifies the new ones to suit.
Windows are replaced room by room, so each opening is only exposed for a short spell. A single window is usually changed within a day, and a typical house takes a few days depending on the number of windows, bays and access. Inside, reveals are finished with trims, sealant or filler.
Modern uPVC casements use multi-point espagnolette locks that engage keeps along the frame, internally beaded glass so units cannot be removed from outside, and key-locking handles. PAS 24 is the security standard expected for easily accessible windows in new homes in England, and it is a sensible benchmark for ground-floor replacements.
In England, replacement windows on a house that look similar to the originals usually do not need planning permission. Flats and maisonettes do not have permitted development rights for replacing windows, and listed buildings, conservation areas and homes under an Article 4 direction may need consent, so check before ordering.

What applies in West Sussex
Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.
Approved Document Q applies to new homes in England, where doors and windows are expected to meet PAS 24 or an equivalent standard. It does not apply to replacements in existing homes, but PAS 24 products are still a sensible choice.
West Sussex has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Near the coast, salt spray and wind-driven rain test seals, drainage and hardware. uPVC itself does not corrode, but stainless or coated locking parts, well-sealed joints around the frame and clear drainage slots matter, and exposed elevations may need frames with higher weather ratings.
Older rural cottages often have irregular openings, thick walls and timber lintels, so every frame is measured individually and the support above each opening is checked. Exposed hillside and open-field sites benefit from reinforced frames and careful sealing against driving rain.

Choosing your uPVC windows
uPVC sliding sash
Vertical sliders that mimic traditional box sashes, using spring balances instead of weights, where planning rules allow uPVC.
Georgian or astragal bars
Bars set between the panes or applied to the faces of the glass for a traditional divided-pane look.
Tilt and turn
Opens inwards from the side for cleaning or escape, or tilts from the top for secure ventilation; practical for flats and upper floors.
Woodgrain and colour foils
Grey, black, cream or woodgrain foils on one or both faces, so the frames can match a door or suit an older house.
uPVC Windows in West Sussex: questions
Can uPVC windows be fitted in a conservation area or listed building?
Sometimes, but consent may be needed first. Listed buildings need listed building consent for significant works, and conservation areas or Article 4 directions often restrict changes to front windows. Woodgrain foils or uPVC sliding sashes can occasionally satisfy a planning officer. Check with your council before ordering; the council can tell you what an application needs, and we can provide product details and specifications to support it.
Can I fit uPVC windows myself?
You can, but the work still has to meet building regulations. In England and Wales, without an installer registered with a competent person scheme you need building control approval and inspection. Accurate measuring, correct packing, fixing and sealing all affect weather performance and how the locks work, and mistakes are hard to put right because frames are made to size and cannot be returned.
Are uPVC windows secure?
Modern uPVC windows can be very secure when they have multi-point locks, internal glazing beads, key-locking handles and laminated glass where needed. PAS 24 is the security standard expected for easily accessible windows in new homes in England. Ask for ground-floor windows tested to it, and avoid frames where the glass is beaded from outside.
How much do uPVC windows cost?
The cost of uPVC windows depends on the size and number of windows, how many sashes open, the frame colour, the glass and the access. White casements with standard double glazing sit at the lower end, while foiled colours, triple glazing and bay windows cost more. See the guide prices for typical ranges; the written quote fixes the price for your specification.
