Bromley: uPVC windows
In England, Approved Document L sets the standard for a replacement window in an existing home: a U-value of 1.4 W/m²K or better, or a Window Energy Rating of band B or above. The new window should also be no worse than the one it replaces. The other UK nations set their own figures.
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.
uPVC frames need washing a few times a year with warm soapy water and a drop of light oil on hinges and locking points. Drainage slots along the bottom of the outer frame let rainwater escape, so keep them clear of dirt and leaves to stop water collecting in the cill.
Bay windows need extra care. Some older bays carry load from the wall or roof above, so the glazier checks the support before removal and may fit bay poles or ask for structural advice. Replacing a window in the same opening is different from widening it, which needs a new lintel.
Included as standard
- Survey and measurement of every opening
- Removal and disposal of the old windows
- Made-to-measure frames with sealed double glazed units
- Written guarantee terms and advice on building regulations sign-off

- Coast
- Bromley is well inland, around 25 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Bromley the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. uPVC frames are bulkier than aluminium, so they take a little more glass area from small windows. On south and west elevations, solar-control or neutral low-E glass limits overheating, while north-facing rooms benefit from high light-transmission glass and warm-edge spacers that reduce condensation.
- Access and setting
- 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.
- Rules in England
- 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 B covers escape windows. Where an existing window is an escape route, typically in first-floor bedrooms, its replacement should give at least the same escape opening as before.
Options to choose between
uPVC sliding sash
Vertical sliders that mimic traditional box sashes, using spring balances instead of weights, where planning rules allow uPVC.
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 Bromley: questions
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.
How long does it take to fit uPVC windows?
Most single windows are changed within a day, and a typical house usually takes a few days. Bays, large picture windows and openings that need a tower or scaffold take longer. Manufacturing comes first, because every frame is made to the survey measurements, and the lead time is confirmed with your quote.
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.
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.
