White uPVC windows across St Albans
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.
Some upstairs windows are escape routes in a fire. In England, the Approved Document B guidance for an escape window is a clear openable area of at least 0.33 m², at least 450mm high and 450mm wide, with the bottom of the opening no more than 1100mm above the floor.
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 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.
Included as standard
- Removal and disposal of the old windows
- Sealing inside and out, with trims to make good

- Coast
- St Albans is well inland, around 59 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In St Albans 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.

uPVC Windows in St Albans: questions
What guarantee comes with new uPVC windows?
Manufacturer guarantees apply to new frames, sealed units and hardware, and the terms are confirmed in writing. Guarantee terms for the installation are set out in writing with your quote, so you know what is covered and for how long before you commit. Keep this paperwork with your building regulations certificate, because buyers' solicitors usually ask for both.
Should I choose double or triple glazing?
Well-specified double glazing with low-E glass and warm-edge spacers can meet the energy standard for replacement windows, and the certified rating confirms it. Triple glazing adds a third pane, which helps on cold, noisy or north-facing elevations, but the units are heavier and need frames designed for them. We can quote both so you can compare.
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.
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.
