White uPVC windows for homes and businesses in Greater London
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.
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.
uPVC no longer means white only. Frames can be foiled in woodgrain or solid colours such as grey, black or cream, often outside only with white inside. Foils are bonded at the factory and should be cleaned with a soft cloth and mild detergent, because abrasive pads and solvents mark the surface.
Low-level glass needs safety glazing. In England, Approved Document K treats any glazed panel within 800mm of the floor as a critical location, so a full-height pane, a low picture window or glass beside a door usually needs toughened or laminated glass, permanently marked to show its classification.

What applies in Greater London
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 F covers ventilation. Replacing windows should not leave a room with worse background ventilation than before, which is why replacement windows often include trickle vents.
Parts of Greater London are within about 15 km of the coast, where exposure to wind and salt air is worth planning for. 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.
In terraced streets and flats, old frames are usually removed and new ones fitted from inside to avoid scaffold. Parking for the van, access through communal areas, leaseholder consent and the lack of permitted development rights for flats all need checking before ordering.

Choosing your uPVC windows
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.
Double or triple glazing
Low-E double glazing suits most homes; triple glazing adds a third pane for lower heat loss and quieter rooms, but units are heavier.
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.
Obscure and acoustic glass
Patterned or satin glass for bathrooms and street-facing rooms, and laminated acoustic glass to reduce traffic noise.
uPVC Windows in Greater London: questions
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.
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.
Do I need building regulations approval for replacement uPVC windows?
Yes. In England, replacement windows are controlled fittings, so the work must meet building regulations. An installer registered with a competent person scheme such as FENSA or Certass can self-certify the work and you receive a certificate; otherwise approval comes from building control. Wales, Scotland and Northern Ireland run their own systems, and we explain which route applies before work starts.
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.
